What’s New in Precise Logon 2.1

Three new main features are introduced with the Precise 100 Logon 2.1 software:

1. To enable biometric logon to a network, the installation of Precise 100 Logon

2.1 software is only needed on the client PCs. There is no need for any

additional software installation on the domain server.

2. The domain administrator has the possibility to remotely administrate user accounts on the domain server by using the BioManager for Domains application, i.e. administration can be done from any workstation in the network having the Precise 100 Logon 2.1 installed. The BioManager for Domains application is included in the Precise 100 Logon 2.1 software.

3. The user has the possibility to remotely (i.e. from his own PC) enrol and re-enrol fingerprints, changing primary logon finger etc. for his own user account, called personal enrolment.

Introduction

Chapter 1 Introduction

Precise 100 A

The Fingerprint Reader

The fingerprint reader includes a sensor for reading fingerprints. When you place your finger on the fingerprint reader, the part of the finger that touches the sensor is read. The sensor measures the capacitance in the finger pad, which reveals the pattern of the fingerprint. Thus, a paper copy with a picture of a fingerprint can not grant access to the system.

The Precise 100 A fingerprint reader

The Fingerprint Identification Process

When logging into a system, your fingerprint is compared to a fingerprint template, i.e. a data file containing information about the fingerprint, stored on a hard disk.

The fingerprint template is a set of characteristics which are unique for one specific fingerprint and not an image of your fingerprint. Your actual fingerprints cannot be recreated using the data from the fingerprint template.

If your fingerprint matches the fingerprint template, the system will grant you access. If the match is not successful, the system will deny access. It takes less than one second for the system to compare a read fingerprint with the information in the database. All information sent between the fingerprint reader and computer is encrypted for maximum security.

At logon, you simply enter your username and place your finger on the fingerprint reader to log into the system!

Chapter 1 Introduction6

Why Use Fingerprint Technology?

In modern society, there is a vast need for secure identification, for instance when logging into computer network. An unauthorised person who obtains access to computer files constitutes a major risk to many companies. In order to prevent unauthorised access, network users have previously identified themselves with a password entered together with the username when logging into a network.

The disadvantages of passwords:

• Unreliable identification. An unauthorised person who knows your password

can easily access your user account.

• A complicated system. In order to increase security, users are regularly asked to

change their passwords. This makes it difficult to remember a password.

• Users forget their passwords, this increase the administration workload.

• Users write down their passwords on notes and store them close to their

applications. This can be a serious security hazard.

The advantages of fingerprint identification:

• Secure identification. By identifying yourself with your fingerprint, you use a

unique “key” to access your user account. All your fingerprints are unique – no person has identical fingerprints.

• Simplicity. It is simple to use fingerprints for identification. You do not have

to worry about changing or memorising passwords anymore – your fingerprint provides secure identification, year after year.

Simply put, with Precise 100 A, you are identified by who you are, not by what you know!

Chapter 2 Installation

Preparing Installation

The Precise 100 A fingerprint reader comes in two versions: Precise 100 A PAR and Precise 100 A USB. The Precise 100 A PAR communicates with the computer through the computer’s parallel port, and the keyboard port or mouse port is used to power the fingerprint reader. The Precise 100 A USB communicates with the computer through the computer’s USB port and does not need additional power.

In the following a picture of a parallel connector indicates a section relevant only to Precise 100 A PAR readers while a picture of a USB connector indicates a section relevant only to Precise 100 A USB readers.

If you are a using a Precise 100 A USB reader you should skip the following two sections and continue with the Installing the Fingerprint Identification Software section. However, if you are using a Precise 100 A PAR reader, follow the instruction below prior to starting the installation.

Setting the Parallel Port

Before connecting the fingerprint reader, ensure that the parallel port is set to ECP mode. It is very important that the parallel port is set to ECP mode before using the fingerprint reader. Otherwise, the fingerprint reader will not function properly. If you do not know whether your computer is in ECP mode (most new computers are), please see the computer manual for additional information, or follow the instructions below.

1. Access the system setup utility. On most computers, this is done by pressing the

F1, F10, Delete or Esc key during system booting – i.e. immediately after the power switch on your computer has been turned on. Keep pressing the key until the system setup, sometimes called the BIOS, appears.

2. Find the parallel port mode. Set the port mode to ECP (sometimes called

Flexible mode). If you are unable to find the port mode, your computer is probably already in ECP mode.

3. Save your changes and exit the system setup utility. If you have problems with

the ECP settings, please contact your computer retailer.

Start the Precise Demo by clicking Start > Programs > Precise Biometrics > Demo.

Chapter 2 Installation

Port Configuration

If you are using Windows NT (only) and your system is equipped with multiple parallel ports, you can specify which parallel port the fingerprint reader is connected to. This is done in the Precise Biometrics Registry Settings. In the rare case you should experience compatibility problems with other software, you may also need to turn interrupts on or off.

1. Click Start > Settings > Control Panel. The Control Panel screen appears.

2. Double-click on the Precise Biometrics logo. The Precise Biometrics Registry Settings screen appears.

3. Make the desired changes and click OK.

Chapter 2 Installation

Attaching the Fingerprint Reader

If preferable, the fingerprint reader can be attached to, for example the side of your monitor. Simply use the adhesive tape at the back of the fingerprint reader. The adhesive tape is very durable and will keep the fingerprint reader attached for many years. The fingerprint reader can be removed and attached again. If the adhesive tape loses its stickiness, replace it with one of the enclosed adhesive tapes.

Before attaching the fingerprint reader, make sure that it will be comfortable for you to use the fingerprint reader in its new place. Try some different positions to find out which is the best before removing the adhesive tape cover strip. If you are right-handed, the right side of your monitor will probably work best, and vice versa.

1. Make sure the surface on which you want to attach the fingerprint reader is perfectly clean.

2. Remove the cover strip from the adhesive tape at the back of the fingerprint reader.

3. Attach the fingerprint reader by pressing it to the surface.

Replacing the Adhesive Tape

If the adhesive tape has lost its stickiness, use the enclosed adhesive tapes. The enclosed adhesive tapes have a cover strip on both sides.

1. Remove the old tape from the fingerprint reader before attaching the new adhesive tape.

2. Remove one cover strip from the new tape and press the sticky side to the fingerprint reader.

3. Finally remove the remaining cover strip and attach the fingerprint reader to the desired surface.

Chapter 2 Installation

Chapter 3

As with most new technology, it might take some training to feel at home logging on using your fingerprint. When you log on and verify your fingerprint, it is important that you place your finger on the fingerprint reader in a proper way. The following chapter contains some examples of good and bad ways of placing your finger on the fingerprint reader.

It is highly recommended that you practice by using the Precise Demo for a few minutes (see Precise Demo in the previous chapter for details).

This chapter includes the following information:

• Placing your finger correctly on the fingerprint reader

• Fingerprint reader maintenance

Using the Fingerprint Reader

Chapter 3 Using the Fingerprint Reader

Placing Your Finger Correctly on the Fingerprint Reader

When you place your finger on the fingerprint reader sensor to identify yourself, please remember two things:

1. It is important that you use the correct finger. For example, if you place your left index finger on the sensor, you will not be granted access if the system expects you to use your left middle finger. When logging on, a screen shows you which finger you are expected to use – it is marked with a dot.

2. Your finger should be properly positioned on the sensor. Poor positioning and too much or too little pressure could result in an erroneous reading – which may prevent you from gaining access to the system.

Correct Finger Placement

Most of the information in a fingerprint is located in the middle of the finger pad. Therefore, it is important that the middle of the finger pad is placed in the sensor centre at enrolment and logon.

• Press your finger pad flat to the sensor.

• Let the top of your finger pad touch the top of the sensor on your fingerprint reader.

• Use medium pressure and avoid rotating your finger.

The following graphics show some examples of different fingerprint images:

Chapter 3 Using the Fingerprint Reader

Rotated finger

Poor image: rotated fingerprint.

Skew finger – too far to the right.

Poor image: off-centre fingerprint.

Chapter 3 Using the Fingerprint Reader

Finger placed too far down on the sensor

Poor image: off-centre fingerprint.

Perfectly placed finger

Good image: fingerprint in the middle, medium pressure to the sensor.

Chapter 3 Using the Fingerprint Reader

When you are placing your finger on the fingerprint reader sensor, it is important that you use the finger marked in the Verify Fingerprint window.

Above is a good fingerprint, which will result in a perfect match and system access.

If the placement is correct, but too much or too little pressure is used, the images will look like this:

Poor image: too dark fingerprint caused by excessive pressure. The finger may also be wet.

Good image from the sensor

Poor image: faint fingerprint caused by insufficient pressure. The finger may also be very dry.

Chapter 3 Using the Fingerprint ReaderChapter 3 Using the Fingerprint Reader

Above is a good fingerprint, which will not result in a match since the fingerprint is not matched with its corresponding template. You may have placed the wrong finger on the sensor, or it could be an unauthorised person trying to log into your account. The system will deny access.

To learn more about how to position your finger on the fingerprint reader, use the Precise Demo. To start the Precise Demo, click Start > Programs > Precise Biometrics > Demo.

High electrostatic discharges might damage the fingerprint sensor. If your Precise 100 Reader is used in an environment where there is a high risk of electrostatic discharges when putting the finger on the sensor, it is important to follow the instructions below.

We recommended to always use the Precise 100 Reader as described here. When putting the finger on the sensor, let your finger slide via the finger guide towards the sensor (see picture).

When putting the finger on the sensor multiple times in a short time period, e.g. during enrolment, you only have to slide via the finger guide the first time you put your finger on the sensor.

Chapter 3 Using the Fingerprint Reader

Fingerprint Reader Maintenance

It is very important that the sensor surface is kept clean. If the sensor is dirty or scratched, there is an increased risk that a fingerprint can not be successfully matched with its corresponding template stored in the database.

• Protect the fingerprint reader from any kind of physical damage.

• If necessary, clean the surface with a clean cotton cloth. You can dampen the cloth slightly with a cleaner.

• Do not use paper tissue for cleaning purposes, since it may scratch the surface.

• Do not spray cleaner directly onto the fingerprint reader.

Personal Enrolment

– Administrating Your Own User Account

Chapter 4

This chapter addresses the process of remotely enrolling a user into the fingerprint database system and registering a user’s fingerprint data.

This chapter includes the following information:

• Administrating your own user account.

• Biometric and non-biometric users.

• Enrolment via the Windows Security screen.

Administrating Your Own User Account

A user can remotely administrate user accounts on a domain server. This includes enrolling and re-enrolling fingerprints, changing the password and changing the primary logon finger. Administration of the currently logged-on user is initiated via the Windows Security screen (or by an administrator using the BioManager for Domains – see The BioManager for Domains chapter for details).

Biometric and Non-Biometric Users

There are two types of user. A biometric user is a user who has been enrolled into the system and who can log on using fingerprints. A non-biometric user is a user who has not been enrolled into the system and can not use fingerprint logon.

Chapter 4 Personal Enrolment

Enrolment via the Windows Security Screen

When the enrolment wizard is started via the Windows Security screen, the user account of the currently logged-on user is pre-selected.

To start the enrolment wizard via the Windows Security screen:

1. Press Ctrl + Alt + Delete.

The Windows Security screen appears.

2. Click Enrolment.

If you are a biometric user the Verify Fingerprint screen appears (see 2.1 below). Otherwise the Verify Password screen appears (see 2.2 below).

2.1. Place your finger on the fingerprint reader.

2.1.1 If you have a password you can choose to log on using this password even

if you are a biometric user. Click Password and the Verify Password screen appears.

2.2. Enter your password and click OK.

The enrolment wizard starts and the User information screen appears.

3. Here you can view your username, your full name and your description.

4. Click Next.

The Reading fingerprints dialog appears.

Chapter 4 Personal Enrolment Chapter 4 Personal Enrolment

In the Reading fingerprints dialog you can register your fingerprints.

6. To register a fingerprint, follow the instructions below:

6.1. Select the finger to register by clicking in one of the checkboxes. Follow the instructions on the screen. Make sure the selected finger is placed on the fingerprint reader sensor.

NOTE: Place the middle of the finger pad on the sensor, to ensure an image rich in fingerprint information.

6.2. After collecting three images of the fingerprint, the best image is automati cally selected and verified against a fourth image. This is done to ensure that the best image is of sufficient quality. Registered fingers will be marked with grey check boxes containing a checkmark.

NOTE: It is recommended that more than one fingerprint is registered, in case a finger gets scratched, etc. To register additional fingerprints, just click in a new checkbox.

7. Click Next when as many fingers as desired have been registered.

The Logon information dialog appears.

In the Logon information dialog you select the primary logon finger. The primary logon finger is the finger that usually will be used to log on or unlock a workstation.

Depending on the administrator’s settings for your account (see The Biomanager for Domains chapter for details), there will also be one of the following choices for the use of passwords:

Chapter 4 Personal Enrolment Chapter 4 Personal Enrolment

7.1 If the administrator has turned off the possibility for users to change pass words in the Windows User Manager, the dialog will look like the one above and there will be no further choices.

7.2 If users are allowed to change passwords, you can enter your new pass word in the Password and Confirm Password fields.

Chapter 4 Personal Enrolment Chapter 4 Personal Enrolment

7.3 If the checkbox Possibility to log on using password appears, you can leave it unchecked to get a random, auto-generated password, which will not be available to you. This means that the only way you can log on is to use your fingerprint.

7.4 If you check the Possibility to log on using password checkbox you will be able to choose your own new password which you will then have to enter twice.

NOTE: Fore more information on passwords see section About Passwords in The BioManager for Domains chapter.

8. Click Next.

The saving screen appears.

About Primary Logon Fingers

The primary logon finger is the finger normally used to log on. The system assumes that the selected primary logon finger is placed on the fingerprint reader when a user logs into or unlocks a workstation. The fingerprint on the sensor is then compared to the primary logon fingerprint template in the database. The user can choose to verify another registered finger when logging on.

The primary logon finger is chosen during enrolment, in the Fingerprint registration wizard. The wizard is accessed by clicking User > New User or User > Properties at the BioManager screen. Any registered finger can be chosen as primary logon finger. To change the primary logon finger, see Checking and Changing a User’s Properties at the end of this chapter.

NOTE: The user can change the primary logon finger using Personal Enrolment. See the Personal Enrolment chapter for details.

About Passwords

It is possible to let a fingerprint user log on with a backup password, if this option is chosen during enrolment. It is not recommended, however, as passwords make it easier for an unauthorised person to log into the user’s account.

NOTE: Only use the password option if the user really needs an alternative to fingerprints for logon.

If the user uses a laptop computer at work and uses the same laptop at home or when travelling, a password could be very useful. At logon, the user can choose to log on using a fingerprint reader or by writing a password.

NOTE: If the password logon possibility is not chosen, the user can only log on using a fingerprint. If a current password user is enrolled into the fingerprint database system, the current password will no longer be valid.

Chapter 5 The BioManager for Domains

Auto-generated Passwords

You can specify whether or not users should be allowed to choose to use passwords.

1. Click Start > Programs > Precise Biometrics > BioManager for Domains.

The BioManager screen appears.

About the Security Level

The security level is an important part of the identification system. A higher security level reduces the risk of an unauthorised person logging into an account. An administrator can set the security level for biometric users. The security level is set globally; i.e. the set security level affects all biometric users in the domain.

The False Acceptance Rate, FAR, is a parameter used to indicate the probability that an unauthorised user is given access to an account. The False Rejection Rate, FRR, indicates the probability that an authorised user is denied access to an account.

A secure system, i.e. a system with a high security level, means a low false acceptance rate.

• Higher security levels = an excellent match between the fingerprint on the sensor

and the fingerprint template in the database is required. The FAR is very low; the FRR is comparatively high.

• Lower security levels = a less perfect match between the fingerprint on the

sensor and the equivalent fingerprint template in the database is required. The FAR is comparatively high; the FRR is low.

Higher security levels (level 6 or 7) result in:

• A very secure system. It will be virtually impossible for an unauthorised person to

log into a user account.

• A system which sometimes rejects an authorised user trying to log into an

account. A small scratch, a distorted fingerprint or poor finger positioning on the fingerprint reader may produce a fingerprint that the system does not accept as a satisfactory match to the fingerprint template stored in the database.

Lower security levels (level 1or 2) result in:

• A less secure system. At lower security levels, the risk of an unauthorised user

logging into an account increases.

• A system which very rarely rejects an authorised user who wants to log into

an account.

Security level 4 is recommended to guarantee a reliable system that grants easy access to authorised users while barring unauthorised users.

When should the higher and lower levels be selected? A lower security level is selected when there is little risk of an unauthorised user attempting to log on, and a very fast verification process is desirable. A higher security level is selected when security is the main concern. In this case, the verification process may take a little longer.

NOTE: An experienced biometric user is less likely to be falsely rejected than a novice biometric user. The FRR decreases as a user gets more used to biometric logon and learns a proper finger placement.

Setting the Security Level

The security level is accessed from the BioManager.

1. Click Start > Programs > Precise Biometrics > BioManager for Domains.

The BioManager screen appears.

2. Click Policies > Account. The Account Policy screen appears.

Passwords and Security Level

If an administrator allows users to log on with a password, a high security level loses part of its function. Even if the system is very restrictive when fingerprints are verified, the security might suffer from users who write down passwords on notepads or choose a very simple password, which can easily be cracked.

Fingerprint Troubleshooting

If the fingerprint verification fails, the red light on the fingerprint reader is turned on.

• Lift your finger and put it back on the sensor. Try to slightly adjust the positioning

of your finger.

• Make sure you placed the right finger on the sensor, i.e. the finger marked

with a dot on the Verify Fingerprint screen.

• Try to log on using another registered fingerprint.

• Place your finger flat on the sensor – not rotated in any direction. See Placing

Your Finger Correctly on the Fingerprint Reader in the Using the Fingerprint Reader chapter for more information.

• Place the centre of your finger pad in the sensor centre.

• Apply enough pressure – the fingerprint reader must be able to detect the

fingerprint contours.

• Your finger must not be wet.

• If your finger pad is too dry try breathing on your finger before verification.

• The sensor must be clean. If necessary, gently wipe the sensor with a soft cotton

cloth dampened with a mild ammonia-based cleaner.

• If using the parallel port, the parallel port must be set to ECP mode. See Setting

the Parallel Port in the Installation chapter for more information.

• Check that the computer and fingerprint readers are properly connected.

See Connecting the Fingerprint Reader in the Installation chapter for more information.

Glossary

Biometric

A biometric is a measurable, unique, physical characteristic. For example, the patterns on your retinas and your fingerprints are biometrics.

Biometric/Non-Biometric User

ECP/Enhanced Capabilities Port

The Precise 100 A PAR and Precise 100 SC PAR readers communicates with the computer via the computer’s parallel port. To make the fingerprint reader and computer communicate properly via the parallel port, the parallel port must be set to a mode called ECP – Enhanced Capabilities Port. Most new computers are set to ECP by default, but not all. See the Installation chapter for details. This does not apply for USB readers.

Enrolment

The process of registering your fingerprints is sometimes referred to as enrolment, as you are enrolled into the system as a biometric user. See Registration for more details.

Finger Pad

The finger pad is the part of your finger containing the fingerprint. If you take a closer look on your finger pad, you will find that most of the information in the fingerprint comes from the middle of the finger pad. That is the part, which should be placed in the middle of the sensor when you register or log on.

Glossary

Fingerprint Reader

The fingerprint reader is used to read a finger placed on the sensor. The sensor measures the capacitance of the finger pad, which reveals the pattern of the fingerprint. Thus, a paper copy with a picture of a fingerprint can not grant access to the system.

The fingerprint reader is used both to enrol a fingerprint to store it in a database, and to verify a fingerprint during logon.

Fingerprint Registration

See Registration

Fingerprint Template

A fingerprint template is a data file containing information about the fingerprint. The fingerprint template is a set of characteristics which are unique for one specific fingerprint and is not an image of your fingerprint. Your actual fingerprints cannot be recreated using the data from the fingerprint template.

Fingerprints

Your fingerprint can be described as a pattern of lines or ridges with valleys in between. The lines form specific patterns that are observable to the naked eye. Loops, arches and whirls are examples of patterns found in a fingerprint.

Some finger print structures

GlossaryGlossary

Guiding bumps

Diode

Sensor

Ending ridge

Ridge

Bifurcation or fork

The fingerprints also include so-called minutiae points. Minutiae points are the points, where a ridge begins, ends or splits. Precise Biometrics’ system identifies a person by looking at loops, arches, whirls and minutiae points, and by measuring global features such as line thickness and curve. These features make every fingerprint unique.

Plug-n-Play

Plug and Play is a technology that supports automatic configuration of PC hardware and external devices. A user can just attach a new device such as sound card or peripheral devices (”plug it in”) and start working (”begin playing”) without having to configure the device manually. Plug and Play technology is implemented in hardware, in operating systems, and in supporting software such as drivers and BIOS.

Primary Logon finger

The primary logon finger is the finger normally used when logging into the system. The system assumes that you place your selected primary logon finger on the fingerprint reader when you log on or unlock a workstation. The fingerprint on the sensor is then compared to the primary logon fingerprint template in the database. For example, if your right index finger has been selected as the primary logon finger, the right index finger is marked on the Verify Fingerprint screen, which appears when you log on or unlock a workstation.

Reader

See Fingerprint Reader

Registration

When you are enrolled into the fingerprint database system, your fingerprints will be registered. You will have to place each finger pad on the fingerprint reader sensor four times. The best image will be saved in a database. Registered fingerprints are used when you log into the system. For example, if your right index finger has been registered, you can place your right finger on the fingerprint reader sensor to verify your identity when you log on. The fingerprint on the sensor will be compared to the registered fingerprint. If your fingerprint on the sensor matches the fingerprint in the database, you are granted access to the system.

GlossaryGlossary

Sensor

The sensor is the black window on the fingerprint reader. The sensor is used to read your fingerprint. Do not “roll” your finger pad when you log on or register a fingerprint. Just press it flat to the sensor.

Template

See Fingerprint Template

Verification

When you register a fingerprint, log on or unlock a system, your fingerprint is verified. During verification, the finger on the sensor is compared to a template of a registered fingerprint from the fingerprint database. In other words, you verify that you indeed are who you claim you are and that the fingerprint on the sensor matches the fingerprint template in the database.
