Introduction

BiometricID, the leader in fingerprint identification and verification systems, presents the Veriprox Fingerprint Verification System. Technology by BiometricID has been applied in various unique applications including Access Security, Time and Attendance, Political Polling, Computer Logon, and other applications where an individual must be clearly identified as being solely responsible for specific actions.

BiometricID was founded in 1996 with a mission to provide fingerprint recognition technology with the highest degree of accuracy at a reasonable cost while still being easy to use. BiometricID has successfully migrated technology once found only in government or military applications, toward private industry and small businesses around the globe.

It has been known for years that each person has unique fingerprints. Using fingerprints as a means of identification ensures a unique id entifier for each tracked user, and protects users from the vulnerabilities associated with lost keys or identification cards. After installing BiometricID’s product in your application, your company will be able to accurately identify, track, and automatically act according to each individual’s identification and permi ssi ons.

About the Veriprox

BiometricID’s Veriprox combines patented fingerprint verification technology with an industry-standard proximity card reader in a mullion-mountable case. This ensures greater security for the card issuer and the card user. Requiring that the fingerprint of the person seeking entry matches the identity of the cardholder eliminates access via lost or stolen proximity cards. Suitable for both standalone and network use, the system works with existing 26-bit proximity card infrastructures.

The unit operates in conjunction with administration software hosted on a PC. Once installed users simply present their identification cards when entering the secure area and then touch a fingertip to the recessed area on top of the unit. The system validates their fingerprint against a previously enrolled template stored in flash memory.

The Veriprox system provides security features that can minimize fraud and can tolerate changes to the user’s finger like scarring or swelling. The Veriprox returns accurate pass and fail decisions in 99.99% of all cases.

Each Veriprox unit stores thousands of fingerprint templates, in a non-volatile memory. Response time is less than five seconds for fingerprint enrollment and less than

1.5 seconds for fingerprint verification. The system is compact, versatile, and configured

to allow standalone, PC-connected, and multiple-unit operation.

Concepts of Operations

The Veriprox

The Veriprox integrates an industry-standard proximity card reader with BiometricID’s MV1100 fingerprint verification technology. A user waves the proximity card near the front of the Veriprox. The LED on the top of the reader will glow amber; indicating the user should place their finger on the sensor on the top of the reader. The ID number is read from the proximity card while the fingerprint is scanned. The amber light will turn off, signaling the finger can be removed. The scanned image is compared with the data that is stored under the ID number in the memory of the Veriprox. If the verificatio n is positive, the top LED will glow green and the unit will emit an audible beep. If the authentication fails, the LED will glow red and no beep will be generated. When authentication is successful a Wiegand string that contains the site code and ID number read from the proximity card is sent out for use by a standard door controller. Optionally, the Veriprox can be configured to send out a pre-determined “failure” ID whenever an unsuccessful verification occurs. An additional option allows the site code to be replaced with another number.

C ONCEPTS OF O PERATIONS

The Veriprox has several communication options. It is equipped with both a Host port and an auxiliary port. The Host port may be configured to operated in RS-232 mode or RS-485 mode. The auxiliary port is always set to RS-232. The Host port connections are made through the wiring pigtail on the back of the reader. The auxiliary port is accessed from an RJ-11 jack that is hidden under a door on the bottom of the Veriprox. This door is held shut with a security screw.

The Veriprox can be used as a stand-alone reader or multiple units can be configured on an RS-485 network. The manner in which you choose to install the Veriprox will determine which commun ications settings are most convenient for your configuration. Certain administrative functions are common to any installation. You must have a way to “enroll” users into the system, that is, you must be able to associate their fingerprint data with a specific proximity card ID number. You must have a way to distribute this user information to all other readers in your installation. The Veriprox Administrative Software is provided for this purpose.

The Proximity Card

There are three types of proximity cards split into two basic categories:

• User Cards

• Enroll Command Cards

• Delete Command Cards

Veriprox Card

Figure 6: Veriprox Card

User Cards

The Veriprox can be programmed to use a given card ID number as a standard “user card”. The majority of your cards will be of this type.

Command Cards

Command Cards can be created to add and remove users from a Veriprox reader without using the PC based Administrative Software. These can be useful for creating and removing temporary visitor’s badges or administering the system when your PC is down or unavailable. There are two types of Command Cards associated with the Veriprox:

• Enroll Command Cards

• Delete Command Cards

Note: The command cards must be created using the Administration Software.

Once a card has been designated as one of the three types, it will remain that type unless it is deleted and re-enrolled (see Edit Templates on page 28 ).

Page 16

Basic System Administration

Enrollment

New users are entered into the system through the process of “enrollment”. This procedure scans the users fingerprint and produces a fingerprint template, a collection of data that is stored in memory on the Veriprox. This includes:

• User Name

• User Finger Identifier

• Template Security Threshold

• Template ID

• Template Index Number

• A mathematical model of the fingerprint ridge pattern

Templates

Every template on a Veriprox unit is unique. Each time a fingerprint is enrolled a new template is generated using the number from the proximity card as the Template ID number. The system automatically increments and assigns an index value to each template.

1. The ID number of the card to which the template is being assigned.

2. The index number of the template; this is assigned automatically by the software. Index numbers differentiate between fingerprints assigned to the same Template ID number (i.e., card number).

Please see Appendix A – Quality and Content on page 48 for a technical description of what constitutes a good enrollment. A quality enrollment will ensure peak performance from the Veriprox fingerprint recognition alg or ithm.

Page 17

C ONCEPTS OF O PERATIONS

Multiple Readers

If your installation includes multiple Veriprox readers that are used by a common population of users, you will need to distribute the fingerprint template of each user to all the Veriprox readers.

Note: It is recommended that you designate one

Veriprox as the “administration reader” and enroll all new users on this unit.

After a new user is enrolled on the administration unit, the template can be copied to the other readers. If the units are networked, you can broadcast the new template to the other readers over the RS- 485 lines using the Administrative Software. If the readers are not interconnected, a laptop can be used to download the templates from the ad mini str ati o n reader and then uploaded to each reader through its Aux Port.

Backing-Up Templates

Templates can be “backed-up” by downloading them to a PC. On the PC, template files are of the type “.tem”. The name of the file is derived from the Template ID Number and the Template Index Number. For example, the first file (1_4.tem) in Figure 8 below is of Template 1 4.

Please note that when the template is uploaded from the PC to a Veriprox reader, the Template ID Number and Index Number is taken from data within the file, not from the file name. Therefore, even if you change the name of the file on your PC, the Template ID and index will remain the same.

V ERIPROX A DMINISTRATIVE S OFTWARE

V eriprox A dministrative Software

The administrative software that comes with the Veriprox unit is designed to run on Windows NT™ 4.0 or Windows 98™ (Note: it is possible to run the software on Windows 95™, however, this is not recommended).

Use the Veriprox Administrative software to perform the following functions:

• Enroll new users and assign them a proximity card ID.

• Distribute the user templates from the administration reader to other Veriprox readers in

the installation.

• Create “command cards”; proximity cards with the privilege to enroll or delete other user cards.

• Adjust the parameters (baud rate, security level, port configuration) of individual Veriprox units, or of all readers connected on an RS-485 network.

• Select specific readers in a networked environment and view and/or edit the templates on those readers.

Concepts of Operation

Transmit ID

On the tool bar of the Administration Software, there is a drop-down list titled Transmit ID (see Figure 10 below). The ID number that appears in the field is the Veriprox reader with which the software currently is communicating. For this reason, each Veriprox reader must be assigned a Network ID, even if your installation consists of a single Veriprox (the default setting is 0).

A special transmit ID number, “-1”, is assigned as a broadcast ID. All Veriprox units will respond to this broadcast ID. For functions labeled “broadcast” the software uses the broadcast ID and all readers on the network will process these commands.

If the transmit ID is set to a number that is not assigned to any Veriprox unit, the software will report that there is no communication.

Figure 10: Transmit ID Drop-down

If two units on the network have the same ID assigned, there also will be communication problems, because both units would respond to commands sent

Page 20

V ERIPROX A DMINISTRATIVE S OFTWARE

to that ID. This causes the information packets to “collide” and become jumbled, resulting in communication losses.

It is important that commands that are broadcast to all readers do not ask for a confirmation reply because all units would respond at the same time jumbling communications.

Ports

The Veriprox “talks to the Administrative Software using either the Host or Auxiliary (Aux) port. The Host port may be configured to use RS-232 or RS-485 protocol. The Host port is connected through the pigtail-wiring bundle at the back of the unit. Different wires are used for RS-485 versus RS-232. The Aux port is accessed using the RJ11 jack at the bottom of the Veriprox. Please refer to the Veriprox Installation Manual (included on this CD) for details.

Serial Port Settings and Baud Rates

Once you have connected the PC to the Veriprox reader(s), you have to identify which ports on the PC are talking with which readers.

As usual, the serial ports on the host PC are designated as COM1, COM2, etc. You may connect up to 31 Veriprox readers to each COM line (using RS-485). You must provide the Administration Software with the information as to which Network ID has been assigned to which COM line.

This information is stored in an initialization file that is read by the software on application startup. The file is labeled “UnitIDs.dat” and is located at the following path:

<Install Dir>\UnitIDs.dat

where <Install Dir> indicates the directory where the Veriprox Administrative Software was installed). The default installation path is:

C:\Program Files\BioID\Veriprox Please refer to the Setting up the ID File section on page 21 for details. In addition the baud rate may be set on each Veriprox reader. It is essential that

the baud rate used by the PC match the baud rate setting on the reader and that all readers on the network are set to the same baud rate.

The following settings are the factory defaults. Your Veriprox should arrive with these settings in place:

Network ID: 0 Host Port baud rate: 9600 baud Aux Port baud rate: 9600 baud Host Port protocol: RS 485

Page 21

Installing the Software

To install the software, run the setup.exe file on the Veriprox Admin CD. You may accept the default path or choose an alternate directory in which to install the software. The default path is:

Like most Windows based installations, you will step through a number of windows (approximately 5) that will request basic installation information, such as, file name and directory location. It is recommended that you use the default settings for these, however, you can change them.

Once the installation is complete, a short-cut icon for the Administration Software will appear on your desktop.

V ERIPROX A DMINISTRATIVE S OFTWARE

C:\Program Files\BioID\Veriprox

Page 22

Setting up the ID File

Once you have installed the software on your PC, you will need to set up a communications port ID file. The software will use the information in this file to communicate with the Veriprox reader(s) connected to the Host Port.

You can create and edit the file using the “Notebook” program provided with Microsoft Windows.

Access the file, UnitIDs.dat located in the Install Directory . The default path is:

C:\Program Files\BioID\Veriprox\UnitIDs.dat

ID File Format

The file format is as follows:

Line 1: Name the comm port on the PC Line 2: List the IDs for all units on this port. Separate each ID by a space. Line 3: Type a % to end the comm port.

Example:

V ERIPROX A DMINISTRATIVE S OFTWARE

COM#: 1 UnitIDs: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 % COM#: 2 UnitIDs: 31 32 33 %

Notice how the line for the Unit IDs for Comm 1 wraps; the software will continue to read the line until the %. A space should appear after each colon (:) and between each reader ID number.

Once you have completed editing the file, save it under the same name and to the same location.

Note: It is essential that this file be located in the

same directory as the Veriprox Administration

software. The default UnitIDs.dat file looks like this: COM#: 1

UnitIDs: 0 %

Thus the software will initialize expecting to find only one reader on the host port with an assigned ID number of “0”. There will be no communication problems if there are other readers on the network unless those readers are also set to ID “0”.

Page 23

V ERIPROX A DMINISTRATIVE S OFTWARE

Communication Settings file

There is a second initialization file that is used by the Administrative Software. This is the CommParameters.cfg file. The program automatically writes this file when it is closed. The next time the program is opened, this file is read and the communication parameters are set to match their state when the program was last shut down.

The first time you run the Veriprox Administrative software this file does not exist. You will see the following dialog appea r. Fill out the desired parameters.

Page 24

Setting up a Network

As described above, when setting up a network you will need to assign unique ID numbers to each Veriprox and confirm the communication settings. The easiest way to do this is to cycle through each reader, setting the parameters by plugging into the Aux port. When using the Aux port you can set the transmit ID to –1 (broadcast). Since you are plugged into only one reader, you are assured that no other Veriprox units will be responding to your commands. If the ID on the Veriprox has been changed from its default you can still be confident it will respond to the Broadcast ID. After you set the parameters for each Veriprox through the Aux Port you can connect them to your 485 network. To review, the recommended steps are:

1 Supply power to the proper wires in the pigtail on the back of the

Veriprox (Consult the Installation Manual for a wiring diagram). When power is applied, the unit will beep, the front LED will glow

green, and the top LED will blink amber, then turn off.

2 Plug into the Aux Port using the RJ-11 jack on the bottom of the unit

and connect the cable to one of the serial ports on your PC

V ERIPROX A DMINISTRATIVE S OFTWARE

3 Access the Communication Settings window by clicking on the icon

or using the menu.

5 Click the Modify button.

Set the Transmit ID to –1. Set the Comm Port setting to match the

designation for the port you are using on the PC (e.g. COM1, COM2) 6 Set the baud rate setting to 9600 baud (the factory default). 7 Press the test button. 8 If necessary, use the Baud Search button to have the software test

different baud rate settings and report which baud setting works. (For

this function to succeed a valid transmit ID and valid COMM port must

be set. 9 Click the Accept button to change the settings. 10 You can now set Network ID on the reader. Click the Veriprox button

on the Modify Communications Settings dialog. 11

Type the desired ID number in the Assign Veriprox Network ID field.

Press the “Set” button to make the change. Note this will change the

ID in flash on the reader. It will not modify the transmit ID that is being

used by the PC. The lower right corner of this dialog box shows the

current communication settings. Since you are using the broadcast ID

(-1) and only connected to one Veriprox (over the AUX port) you will

continue to communicate without problems.

Page 25

V ERIPROX A DMINISTRATIVE S OFTWARE

Select the appropriate baud rate from the Host Port Baud Rate drop

down list (9600 is recommended). Keep in mind that you are currently

talking over the AUX port, but you are changing the Host Port settings

that will be used when you connect to the Veriprox through the Host

Port wires on the back of the unit. 13

Set the Host Port Protocol to RS-485 if you will be using a networked

environment. Alternatively you may choose RS 232 if you will not be

networking the Veriprox. Remember that the RS 232 and RS485

connections are made through different wires on the pigtail. (Consult

the installation manual.)

Make sure that the Network IDs in the UnitIDs.dat file match those assigned to the readers. If not, update accordingly.

Global Security Threshold

There are two types of security settings: the local security level associated with the individual template; and, the global security level associated with the individual Veriprox unit. You may recall that the system will authorize using the lower of the two. See the appendix for a discussion of security settings and algorithm performance.

Example: If the template is set for Very High, and the unit is set

for Medium, the authorization will be performed at the Medium setting.

Because of Veriprox’s high accuracy rate which practically negat es the possibility of a false read, the above affords the unit a high rate of true authorization.

Appendix A – Quality and Content

Section A.1 - Basic Biometric Concepts

Biometric Definitions

Enrollment is the operation of scanning a fingerprint, determining the quality of the fingerprint scan, and storing a good template with associated data within the memory of the Veriprox.

Verification is the operation of presenting the user ID, either by waving a proximity card or typing the ID into the Verify dialog box, requesting the user to place their finger on the Veriprox, scanning the finger, comparing the current scan against stored fingerprint templates for that user, and then notification of a successful validation or a failure.

Fingerprint Template is the term used to describe the data stored on the Veriprox that mathematically represents the ridge pattern of an enrolled fingerprint. This data is not the raw image of the fingerprint, but the result of processing a raw image through our unique algorithmic process, preparing the data for later comparisons, and compressing the data for maximum storage. An image of the uncompressed template data does resemble the raw image, but whereas a raw image is 90K bytes, the compressed template is only 348 bytes.

Fingerprint Core is the term used to describe distinguishing print characteristics usually found in the area of the print where the topography shows the tightest curvature. Although the entire fingerprint has significant data, the “core” is the most data-intensive area and therefore very important.

Scanning an Image

When the Veriprox properly reads a fingerprint, it looks for image quality and fingerprint content. When a raw image is collected from the sensor, the Veriprox searches for the fingerprint core.

Page 50

A PPENDIX A – Q UALITY AND C ONTENT

Content scores are based upon the amount of non-ambiguous data in the region of the core. The higher the content, the greater the degree of useful information. See Section B.3 for a thorough discussion of content

Quality scores are based on how well the ridge pattern is defined within the image. For best image quality, be sure that the sensor window is clear of dirt, residue, or other material that can block the Veriprox’s view of the fingerprint. See Section B.3 for a thorough discussion on quality.

Once the image is scanned, the Veriprox then creates and stores the resulting fingerprint template.

Storing User Templates on the Veriprox

The Veriprox recognizes users by matching current images to stored templates of previously enrolled fingerprints. Along with the fingerprint, the Veriprox requires a proximity card with a unique user ID number.

The Veriprox allows associating multiple fingerprints with a single proximity card. Each instance of a template with a specific Id has a unique index (up to 256 indices possible (0-255)). This allows a user to have a single proximity card, but be able to enroll multiple fingers. During VERIFICATION, a user waves their card at the Veriprox reader and places their finger on the sensor. The Veriprox then will scan the current fingerprint and compare it against all enrolled templates for that specific card. If there are multiple templates enrolled under one card, then the Veriprox will check templates in the numerical order based on their index.

Example: On Card # 123, a person ENROLLs both their left and right index

fingers. The next time that user goes to verify, they wave Card # 123 and place a finger on the sensor. The Veriprox scans the current finger and compares it against the first template (the right index finger, Template ID 123 0). If a match is found, the VERIFICATION is PASSED and the operation ends. If a match is not found, the Veriprox will check the second print (the left index finger, Template ID 123 1). If a match is found, the VERIFICATION is PASSED and the operation ends. If the match is not found and since all templates have been compared, the VERIFICATION is FAILED.

NOTE: The initial finger scan takes ~0.5 seconds and each comparison

takes ~0.5 seconds. So if the first template results in a successful verification, the total time is ~1.0 seconds. Successful verification on the second templates requires ~1.5 seconds, and so on.

Page 51

A PPENDIX A – Q UALITY AND C ONTENT

Section A.2 - Proper Finger Placement

The basics for successful operation of the Veriprox are simple but important. System performance improves dramatically with consistent finger placement. It is important to make sure that the position of the finger allows the Veriprox to record the unique features of the print. Here are the steps to follow for trouble-free fingerprint recognition.

• BII has designed the Ridge-Lock to create “simple user instruction” and

“consistent” finger position. With the fingertip raised, position the finger so that the Ridge-Lock rests comfortably within the first indentation of the finger. Next, lower the finger onto the sensor and apply moderate pressure.

Common mistakes

Correct finger placement is a significant component for reliable fingerprint imaging. The following list some common mistakes to avoid.

• Sliding the fingertip into place instead of lowering it onto the sensor will cause distortion of the fingerprint and will degrade image quality. Keep the fingertip raised while locating the Ridge-Lock, then lower the fingertip.

• Rotating the finger into position also will cause distortion of the fingerprint, subsequently making verification less reliable.

• Positioning the finger to one side and leaving a portion of the sensor exposed will degrade image quality.

• Placing the finger at an angle to the finger guide is another common mistake. Rotation of the fingertip will not provide a reliable image of the fingerprint.

Image quality

Dry skin is another factor that can contribute to an unreliable image of a fingerprint. A normal amount of moisture on the skin makes the ridges and valleys of the fingerprint stand out to the sensor. Too little moisture makes the image “noisy” and will “cause Veriprox to reject the image during processing. Lightly moisturizing the finger will enhance the contrast of the print and provide more reliable verification. The increased sensitivity of the silicon sensor is dramatically reducing problems in this area.

Page 52

A PPENDIX A – Q UALITY AND C ONTENT

Image consistency

Once a user’s fingerprint template has been enrolled, the best performance in the candidate matching process depends on consistency. Obviously, the user must use the same finger for ID verification as was used to form the original template. It also is important to position the finger correctly for each verification, as was done when the template was enrolled, so the Veriprox “sees” approximately the same information each time.

Page 53

A PPENDIX A – Q UALITY AND C ONTENT

Section A.3 - Using Content and Quality during Enrollments

As described in section A.1, Quality and Content scores are returned in the enrollment process. These scores give an indication of the performance of the template enrolled. To a large degree, the verification algorithm compensates for deficiencies in image quality and loss of information content. Nonetheless, knowledge of these parameters and what they mean helps ensure optimal performance of the Veriprox.

False Acceptance and False Rejection

In order to understand the effects of poor image quality and poor information content it is necessary to understand how to measure performance. Performance of the Veriprox is presented in terms of False Rejection and False Acceptance.

False Rejection indicates that the Veriprox incorrectly rejected a fingerprint that corresponds to the person’s template. False Rejections rarely occur and primarily result from the inability to get a good image of the finger.

False Acceptance indicates that the Veriprox accepted a fingerprint that does not correspond to the template it was compared against. False Acceptances also are rare and primarily result when a fingerprint template is characterized by low information in the enrolled print.

The algorithm on the Veriprox has been tuned so that the false acceptance and false rejection rates are equal at the medium security level (level 3), delivering the industry leading accuracy. This is known as the Equal Error Rate. Increasing the security (e.g., changing the security level from 3 to 1) will decrease the chance for false acceptance at the expense of increased false rejection. Reducing the security (e.g., changing the security level from 3 to 5) will decrease the chance of a false rejection at the expense of false acceptance. The table below indicates the expected error rates at the different security levels.

Security Level False Rejection Rate False Acceptance Rate

Very Low (5) 1 / 10,000 1 / 100

Low (4) 1 / 5000 1 / 200

Medium (3) 1 / 1000 1 / 1000

High (2) 1 / 200 1 / 5000

Very High (1) 1 / 100 1 / 20,000

Page 54

A PPENDIX A – Q UALITY AND C ONTENT

Quality

The quality score is based on how well the ridge pattern is defined within the fingerprint image that was enrolled. In other words, quality measures how clearly the Veriprox imaged the fingerprint. Poor quality enrollments can result in an elevated rate of false rejection making it difficult for the user to verify reliably.

The score is given in stars () and ranges from zero to five stars, with five being the best quality (rarely obtained) and zero being the worst. Quality scores of three stars and higher perform well with the BII verification algorithm. In this range, the algorithm readily compensates for differences in fingerprint quality. It statistically is still true that the larger the quality score the better the performance of an enrollment.

As a general rule of thumb, quality scores less than three stars require intervention on the part of the enroller or ad mini str ative software. Sources of low scores include dry fingers and dirty sensors.

Very Low Very High

If the quality score falls below three stars, BII recommends the following options:

• Ensure that the sensor and finger are clean.

• If the finger and sensor are clean and a dry finger is suspected, try re-enrolling

one more time, leaving the finger on the sensor for several seconds prior to enrollment. Frequently finger moisture accumulates over time to provide a good image.

• Fingerprint quality can vary among individual fingers for the same person. Try

enrolling an alternate finger to see if the score improves.

• Alter the security level for that particular template by decreasing the threshold

a minimum of 1 level (e.g., change the value from medium [3] to low [4]). This will offset the false rejection for that template by making it easier to match. If use of that template indicates that raising the threshold one level still produces false rejections, try setting the value to its lowest security (level 5).

Warning: Decreasing a template’s security may increase the risk of a

false acceptance for that template.

A thorough enrollment procedure will ensure streamlined and reliable verification for users. It is recommended that all four options be performed in the order listed above to maximize the performance of the device.

Page 55

A PPENDIX A – Q UALITY AND C ONTENT

Content

The Content score is based upon the amount of usable information the Veriprox sees in the fingerprint. Templates that are characterized by low content scores may result in elevated rates of false acceptance.

Again, the score is given in stars () and ranges from zero to five stars, with five being the most content and zero being the least. Content scores of three stars and higher perform well with the BII Algorithm. In this range the algorithm has enough information to distinguish between different fingerprints with a high level of accuracy. Templates with content scores above two stars do not vary in terms of the error rate s.

Content scores less than three stars require intervention on the part of the enroller or administrative software. Sources of poor content include improper finger positioning and extremely bland fingerprints.

Very High Low Content

If the content score falls below three stars, BII recommends the following options:

• Try re-enrolling the same finger if finge r po sitioning seems to be the issue (see section A.2). Ensure that the user can comfortably place the finger on the sensor while maintaining the core region in the image.

• Fingerprint content can vary among individual fingers for the same person. Try enrolling an alternate finger to see if the score improves.

• Alter the security level for that particular template by increasing the threshold a minimum of 1 level (e.g ., change the v alue fro m medium [3] to high [2]). This will offset the false acceptance for that template by making it more difficult to match. If use of that template indicates that raising the threshold one level still produces false rejections, try setting the value to its highest security (level 1).

Warning: Increasing a template’s security may increase the risk of a false

rejection for that template.
