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 finger-
print 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 log-
ging 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!

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 sec-
tions and continue with the Installing the Fingerprint Identification Software section. How-
ever, 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.

Continue with the next step – Installing the Fingerprint Identification Software.
Installing the Fingerprint
Identification Software
NOTE: Only users with administrator rights can install the software.
The fingerprint identification software, Precise 100 Logon 2.1, is needed to read your fin-
gerprints and to save and retrieve information about your fingerprints, accessible
domains, etc.
During installation you may be instructed to restart your computer before continuing to the
next step in the installation procedure. If the Master Setup screen does not appear auto-
matically after restart, start the CD from your desktop by double-clicking My Computer >
CD > MasterSetup.exe icon.
NOTE: Once the software is installed, you will be able to register fingerprints using the
BioManager for Domains (see The BioManager for Domains chapter for details) and store
them locally if you log on as administrator on your local workstation. However, that will
not grant access to domain server accounts. To be able to log into a domain server
account using your fingerprint, your fingerprint will have to be registered and stored on
the domain server.
When the fingerprint identification software is installed on your local computer, you can
use Personal Enrolment to register your fingerprints on the domain server. See the Personal
Enrolment chapter for details.

Attaching the Fingerprint Reader
If preferable, the fingerprint reader can be attached to, for example the side of your mon-
itor. 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 finger-
print 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 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. There-
fore, 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

Skew finger
– too far to the right.

Finger placed too far down on the sensor
Poor image:

Perfectly placed finger
Good image:

Chapter 3 Using the Fingerprint Reader
23
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 exces-
sive 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
24
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 put-
ting 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.

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.

– Administrating Your Own User Account
Chapter 4
This chapter addresses the process of remotely enrolling a user into the fingerprint data-
base 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.

Introduction to the
BioManager for Domains
Using the Biomanager Administrators can:
• Choose which domain and user account to administrate
• Add and delete users
• Register fingerprints
• Turn password users into biometric users
• Decide whether a biometric user is allowed to use a password as backup
• Change properties for users
• Set the security level for the system
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
Users are listed in the BioManager with a symbol next to each username. The following
symbols are used to define a user’s current status:
Biometric user, with fingerprint information stored on the hard drive.
Biometric user with fingerprint information stored on smart card.
Non-biometric user. Can not log on using a fingerprint yet, must use a password

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 cho-
sen 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.

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.
2. Click Policies > Account. The Account Policy screen appears.
If Allow users to use auto-generated passwords is checked (default) users will have the
possibility to choose whether or not they want to have a random auto-generated pass-
word. If the user chooses to use an auto-generated password he will not to be able to
log on using a password.
If you uncheck Allow users to use auto-generated passwords users cannot choose to use
auto-generated passwords. The user may however still type in a password that can be
used for logon.

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 secu-
rity 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 verifi-
cation 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.
Set the security level and click OK. Security level 4 is recommended for most purposes.
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 secu-
rity might suffer from users who write down passwords on notepads or choose a very sim-
ple password, which can easily be cracked.

Fingerprint Registration
In order for a user to use a fingerprint to log on, the fingerprint must be read and stored
in a database – i.e. it has to be registered. The fingerprint data will be stored on a hard
drive.
Only an administrator can register fingerprints using the BioManager. To enrol a user,
whose username is not on the username list, see Beginning Fingerprint Registration of a
New User in this chapter. To enrol a user listed in the BioManager, see Beginning Finger-
print Registration of an Existing User in this chapter.

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.

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
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.
ECP/Enhanced Capabilities Port
The Precise 100 A PAR and Precise 100 SC PAR readers communicates with the comput-
er via the computer’s parallel port. To make the fingerprint reader and computer communi-
cate 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
60
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 fin-
gerprint 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 sys-
tems, 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 reg-
istered. 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 fin-
gerprint on the sensor matches the fingerprint in the database, you are granted access to
the system.
61 GlossaryGlossary
62
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.
