1.0 SCOPE

This document is intended to provide guidance to the end user of the Personal

Identification Credential System (PICS) for normal operations. It is intended to cover only the Proof of Concept iteration of the PICS. It describes typical operation of the

Personal Identification Credential (PIC), the PICS Enrollment Station, and the PICS

Reader.

In general, the roles discussed within this document cover the PIC user, the PICS

Enrollment Station operator, and the PICS maintainer. The PIC user need only be concerned with the operation of the PIC itself. The PICS Enrollment Station operator will need to be familiar with both the PIC operation and the PICS Enrollment Station operation. The PICS maintainer will need to be familiar with all three roles.

3.0 DESCRIPTIONS

The Personal Identification Credential System (PICS) is intended to provide access control using a Personal Identification Credential (PIC), which can be issued to individual users. The PIC will be a small, handheld, wireless biometric device small enough to fit in a shirt pocket. In the initial application, users will operate the PIC from within a vehicle in order to gain access to a facility.

In addition to the PIC, the system will include a PICS Enrollment Station, which consists of a MS Windows based PC software application with an RF interface attached to a serial port. The Enrollment Station software will run under the MS Windows environment and provide enrollment capability and enrollment database maintenance.

Lastly, the PICS Reader is used to control access of users to the system. The PICS

Reader provides interrogation of PIC units and validation of PIC enrollment. The PIC is responsible for validating the fingerprint, but the Reader is responsible for insuring that a given PIC is to be allowed in the system.

The operation of the PIC is straightforward, but the nature of the biometric fingerprint sensor is such that the user will need to become well practiced in using it. The guidelines given here may not work for everyone. Some users may find that a different approach to using the sensor will yield better results. Unfortunately, the typical user will have little time to experiment with using the PIC before being permanently enrolled in it.

The PIC automatically turns itself off after approximately 5 to 10 seconds. The act of sliding open the fingerprint sensor activates the electronics inside. The PIC will emit a short high pitch beep and briefly flash the LED yellow to indicate that it is alive. If the batteries are getting low, the PIC will emit three short low pitch beeps and briefly flash the LED red. If the batteries are too low, the PIC may not have enough power to function correctly. The batteries should be replaced immediately upon receiving a low battery indication.

Once the PIC is turned on, it will immediately start scanning for a valid fingerprint. It is important for the user to be consistent in applying the finger to be tested. In order to facilitate the correct application of the fingertip, the user should place the fingertip in the indented portion of the slide cover, then slide the cover open and place the flat part of the

fingertip on the sensor. Figure 1 shows correct and incorrect placements of the fingertip

on the sensor.

PICS POC User’s Manual 13 January 2003

Correct Incorrect

Figure 1 PIC Fingertip Placement

Once the finger is placed on the sensor, the LED should light indicating the status of the verification. If the LED does not light, the most probable cause is dry skin. In this case, moisten the fingertip and start over. If the LED does illuminate, the color of the LED

will represent the current state of the verification process, as shown in Table 1.

Table 1 PIC LED Status

The PIC is still processing the image or the image is of poor quality. If the

LED remains amber for more than a few seconds, remove the finger and reapply.

Red indicates that the PIC was unable to match the finger to one of its stored templates. This could be due to changes in the fingertip, such as damage to the skin or varying skin conditions. It could also be due to improper positioning of the fingertip on the sensor. Removing the finger and reapplying it will frequently solve this problem.

PICS POC User’s Manual 13 January 2003

Green indicates that the fingerprint was matched successfully. A green LED should be accompanied by a single, short, low pitch beep. Initially, the LED should blink green. Once the PIC has received confirmation from the PICS

Reader that the PIC has been validated, the LED will remain on continuously and another short, high pitched beep will be emitted. If the PIC fails to receive validation from the Reader by the time the timeout occurs, three short high pitched beeps will be emitted prior to the PIC shutting itself down.

The PIC will generally time out between 5 to 10 seconds after being turned on, depending on the status of the PIC and other factors.

3.2 Enrollment Station Operation

The Enrollment Station operator is responsible for enrolling users into the PICS system.

This task is accomplished via the PICS Manager software package running on the

Enrollment Station PC. The Enrollment Station operator must be familiar with most of the PICS Manager software and the operation of the PIC units. The Enrollment Station operator most likely will be required to train PIC users during the enrollment process.

Some portions of the PICS Manager software are intended for maintenance and troubleshooting operations, and as such will pertain only to the PICS maintainer. In addition to the PICS Manager software itself, the Enrollment Station must have access to an Interbase SQL database (either on the local PC or a remote PC connected via Ethernet)

with tables configured as described in paragraph 3.2.2. When the PICS Manager

software starts, the operator will be prompted to enter a username and password for the database. The user name and password must be created by the maintainer. Some operations at the Enrollment Station can be performed without the Ethernet connection to the Reader being established. However, some operations, including everything which can be accessed via the Reader screens and Reader database updates, will require the

Ethernet connection to be established.

The first tab on the PICS Manager screen selects the Users

screen, shown in Figure 2.

This screen is used to add and remove users from the PICS database. A set of buttons at the top left of the Users screen allows the operator to navigate and edit the database. This includes buttons to add and delete records, edit existing records, and post or cancel current edits. The operator will need to fill in the Name , User ID , and Duress ID for each user entered in the database. The Name is for the convenience of the operator only, and is not used by the rest of the system. The User ID is the string which the Reader will output upon a successful match with the PIC when the user uses any of the enrolled fingers except the designated duress finger. If the user uses the designated duress finger, the Reader will output the Duress ID string. The only other field which the operator will be interested in is the PIC ID field, which is set when the user is properly enrolled in the system. If the PIC ID field is blank, the user has not been enrolled in the system. If a

7

PICS POC User’s Manual 13 January 2003

PIC which has already been used is re-enrolled with a new user, the original user will no longer be enrolled on the PIC. However, he may not automatically be removed from the database. To remove a user from the database, the operator will be required to manually remove the user from the database.

Figure 2 PICS Manager Users Screen

The ENROLL button is used to enroll the currently selected user. It is only available if the user is not currently enrolled ( PIC ID must be blank). Pressing this button will activate the Enroll screen and select the current user for enrollment. It will not actually start the enrollment process.

The Enroll

screen, shown in Figure 3, is used to actually enroll a user into the system.

This screen can also be used to test a PIC once a user has been enrolled, or to allow the user to practice using the PIC. The Enroll screen is divided into four parts. The enrollment operator should be certain that one and only one PIC is activated near the

Enrollment Station during the time when enrollment or testing is occurring, as the

Enrollment Station may not be able to distinguish one PIC from another.

8

PICS POC User’s Manual 13 January 2003

Figure 3 PICS Manager Enrollment Screen

3.2.1.2.1 Enroll

This section provides the controls to actually perform the enrollment. The first field is a drop down list of the available User ID s to be enrolled. If the Include Previously

Enrolled IDs checkbox is checked, the list will include all User ID s currently in the database. If it is unchecked, only the disenrolled users (users with a blank PIC ID in the database) will be in the list. If this screen was activated by pressing the ENROLL button on the Users screen, the user selected on that screen will be in the User ID field. The

Name and PIC ID fields are retrieved from the database for the User ID in the User ID field. This section also contains the Enroll , Enroll Finger , Enroll Duress and Disenroll buttons, which will be discussed later.

3.2.1.2.2 PIC Status

This section displays the status of the PIC that the Enrollment Station is in current communication. The Status field will display the last received status from the current

PIC and will clear whenever a communication timeout occurs. Just below the Status field is a bar graph which gives a visual indication of the time since the last valid status was received. The end of the bar graph represents approximately 10 seconds, after which a communication timeout is assumed. The Last ID field will display the PIC ID of the last status received. The # of Templates field shows the number of templates currently enrolled in the PIC from which the last status was received. Enroll Mode indicates that the PIC is currently in Enroll Mode, and Duress Enrolled indicates whether the PIC has a designated duress fingerprint enrolled. Enable Log turns on a log display in the lower portion of the screen for diagnostic purposes. Clear Log clears that log display. The log display is generally only used by the maintainer for troubleshooting purposes.

9

PICS POC User’s Manual 13 January 2003

3.2.1.2.3 Test

This section contains four buttons which are used for testing only. The first button,

Local Test , is useful for the enrollment operator to allow the PIC user to practice using the PIC. It allows the Enrollment Station to act like the Reader and provide validation of user access. With the Local Test enabled, the enrollment operator will be able to see if a match occurs, if a duress match occurs, if no match occurs, or if the fingerprint image quality is poor. This gives the PIC user a chance to practice using the PIC in a controlled environment. If the PIC user is unable to operate the PIC properly at this point, the enrollment operator may need to re-enroll the user.

The Version button will cause an activated PIC to send its identification and version information. This information will be displayed on the log display only if it is enabled.

This is primarily intended as a diagnostic tool for the maintainer and should not generally be used by the enrollment operator.

RF Test will place the Enrollment Station in a test mode which will cause any activated

PIC to constantly respond with a message. This mode is primarily used for Reader checkout, but using it on the Enrollment Station can help diagnose a PIC which is not communicating properly. With RF Test enabled, the PIC should have a solid red LED as long as it is receiving data from the Enrollment Station. It also will continuously respond with an ID message, which the Enrollment Station should indicate on the timeout bargraph in the Status section. This is primarily intended as a diagnostic tool for the maintainer and should not generally be used by the enrollment operator.

Reader RF Disable is used to disable the RF from the Reader for a period of 60 seconds. This is only necessary if the Enrollment Station is in close proximity to the

Reader and experiences RF interference during enrollment and testing. For this function to work, the Ethernet connection between the Enrollment Station and Reader must be established.

3.2.1.2.4 Display Log

The display log, as described previously, can be used by the maintainer to troubleshoot problems with the Enrollment Station or a PIC. This display will generally show the status messages from a PIC, along with the PIC ID. It gives the maintainer the ability to see the history of the status messages.

3.2.1.3.1 Beginning Enrollment

If the user is not enrolled, the Enroll button will be enabled. If the user is enrolled, the

Disenroll button will be enabled. To actually perform an enrollment, the user must activate the PIC by sliding the sensor cover up (the finger does not need to be on the sensor at this time) prior to pressing the Enroll button. If the PIC was not activated prior to pressing the Enroll button, the operator must press the Enroll button again to deactivate the enrollment mode, and then activate the PIC. If the PIC is activated when the Enroll button is selected, the LED on the PIC should blink amber for approximately 5

10

PICS POC User’s Manual 13 January 2003 to 10 seconds while it prepares for enrollment. Note that once the PIC has started this enrollment process, any previous enrollment information will have been removed and is no longer accessible.

Once the PIC has finished preparing for enrollment, the

PIC LED will turn off and a short beep will be emitted by the PIC, and the PIC status on the enrollment screen will indicate IDLE .

3.2.1.3.2 Enrolling a Finger

Once the PIC is in the enrollment mode, the operator should press the Enroll Finger button to allow the user to enroll a finger into the PIC. When the Enroll Finger button is pressed, the PIC will respond with a PLACE FINGER status. At this time, the user should place a finger on the sensor in the correct position. Once the PIC has acquired that image, the status will change to REMOVE FINGER . The user should then remove the finger from the sensor. The process will be repeated two more times. After the third image is acquired, the PIC will attempt to create a template using the three images. If the three images fail to correlate, the finger enrollment will fail and the Enroll Finger button will turn red. If the enrollment is successful, the button will turn green. The user can then test the template by applying the finger again. The user should be able to get a match using that finger.

It is recommended that the user enroll several fingers to allow for problems which may occur with a particular finger.

3.2.1.3.3 Enrolling a Duress Finger

The user may enroll a particular finger as a duress finger. The process is exactly the same, except the enrollment operator must press the Enroll Duress button instead of the

Enroll Finger button. The Enroll Duress button may be used multiple times during the enrollment, but only the last fingerprint enrolled as a duress finger will be designated as such. All the previously enrolled fingerprints will be normal fingerprints. The purpose of the duress fingerprint is to allow the PIC user a means of activating the system correctly, but alerting the system operator that something is wrong. For this reason, it is very important that the user be able to remember which finger is the duress finger.

3.2.1.3.4 Finishing the Enrollment

Once the user has enrolled all the desired fingerprints, the enrollment operator should click the Enroll button again to deactivate the enrollment mode. This action will cause the PIC to send some enrollment data back to the enrollment station for placing in the database. If this process does not complete, the PIC will NOT be enrolled in the database, and the user will not be able to access the system. If the enrollment completes correctly, the user’s PIC ID in the database should go from blank to having a valid ID, in the form xx.xx.xx.xx.xx.xx.xx.xx. This can be verified by observing the user’s entry in the database on the Users screen.

The Reader screens (there are three of them) are typically used by the maintainer only.

11

PICS POC User’s Manual 13 January 2003

3.2.1.4.1 Monitor Screen

The Monitor screen provides a means for the maintainer to view status messages from the

Reader. In this screen, the maintainer can also enable the RF Test mode, which causes the Reader to begin sending RF test messages. Any activated PIC which receives an RF test message will immediately respond with an ID message. This allows the maintainer to verify the Reader RF radiation pattern, as well as troubleshoot general RF problems.

Figure 4 shows the

Monitor screen.

Figure 4 PICS Manager Reader Monitor Screen

3.2.1.4.2 Database Screen

The Database screen can be used by the maintainer to verify the contents of the Reader database, clear it out, and force a new download of the database. Under normal circumstances, the Auto Update button should always be selected. After using this screen, the maintainer/operator should ensure that this button is selected. If this button is not selected, the database in the Reader will not be kept up to date. The Reader

Database

screen is shown in Figure 5.

3.2.1.4.3 File Transfer Screen

This screen provides the ability to send and receive files to/from the Reader. This screen should only be used by qualified personnel, as changing the wrong file could prevent the

Reader from booting. The File Xfer

3.2.1.5.1 Communication Port

This field sets the comm. port to be used for the Enrollment Station RF Interface Unit.

Note that the baud rate, parity, etc. are all fixed and cannot be changed by the maintainer.

3.2.1.5.2 Database Location

This field specifies the location for the Interbase database file. This location is determined during the initial setup of the database. To specify a database on the local machine, just type in the location as specified in the Interbase database definition. To specify a remote database, enter <computer name>:<database location> , where computer name is the name windows networking uses, and the location is the path of the file, excluding the drive specifier (e.g. ‘ PICS_ENROLL:\PICS\Database\PICS ’).

3.2.1.5.3 Reader IP Address

This field sets the Reader’s IP Address. The Reader must use a fixed IP address, which should be entered into this field. Changing the Reader’s IP address is discussed later in this document.

3.2.2 Interbase SQL Database Configuration

This operation should be completed only by the PICS maintainer. Once the Interbase setup is complete (refer to Interbase documentation), create a database and execute the

14

PICS POC User’s Manual 13 January 2003 following SQL script. This will create the database with the required tables and fields.

Make note of the physical location of the database to set in the configuration screen.

The PICS Reader contains an embedded PC running an embedded operating system. The

Reader software uses an initialization file called reader.ini, which is located in the root directory. A keyboard and monitor may be attached to the Reader for troubleshooting purposes and configuration management. In addition, the reader.ini file may be updated via the File Transfer screen in the PICS Manager software (assuming the Ethernet connection to the Reader has been established) or by placing a new file on a floppy in the floppy drive during the first 30 seconds after the Reader software has started to run.

The Reader takes about 35 to 40 seconds to begin operating after power is applied. Once the Reader has booted, the LED on the OPTO-22 module in position 5 should start to blink. This is an indication that the Reader is operating normally. In addition, during the first 30 seconds after starting, the LED on the OPTO-22 module in position 2 will blink, indicating that the Reader is looking for new files in the floppy disk drive. Within that 30 second window, placing a floppy with a new reader.ini file in the drive will cause the

Reader to copy the new file to the hard disk. The Reader must then be rebooted in order for the new file to take effect. If the new file loaded has incorrect settings, it is possible that the Reader will not function correctly. In this case, it will be necessary to reload a correct file. A sample listing of the reader.ini file is shown below.

Refer to EG&G Drawings 126764-10, PICS Installation and 126762-10, Assy, PICS

Reader Terminal Unit.

CAUTION

This unit is powered by 120 VAC. This voltage can be extremely dangerous and can cause death. Always use an insulated probe when attempting to measure 120 VAC and be extremely careful not to touch places where this voltage is present.

The PICS Reader Terminal Unit is contained in a 16” x 16” x 8” NEMA 4X enclosure.

This enclosure may be mounted on a wall by using the tab mounts or pole mounted on a

3 or 4 “ pole by using Unistrut cross channels and U-bolts. There are two ¾” conduit entrances in the bottom of the enclosure, the right-hand entrance is for the 120vac power and the left-hand entrance is for the data communications cables (RS-232 three wire and

100BaseT). Liquid tight flexible ¾” conduit is recommended for these connections.

Follow NEC and local electrical codes. The AC power is connected to the right hand terminal block on the back panel of the unit. The AC ground wire is connected to the ground terminal in above the AC terminal block. The RS-232 cable should be terminated with a DE-9S female connector and connected to the RS-232 transient protector. The

100BaseT cable should be terminated with a Category 5 RJ-45 connector and connected to the 100BaseT transient protector.

WARNING

Installation of antenna near power lines is extremely dangerous and can result in death. Follow installation instructions packed with antenna .

This description assumes that the Enrollment Station PC has been set up and configured prior to installing the Enrollment Station hardware and software. Place the Enrollment

Station RF Interface box in a convenient location for use during PIC enrollment. The location should provide a clear path to the PIC which enrolling users will be holding.

Connect the Enrollment Station RF Interface RS-232 9 pin connector to an unused COM port on the PC via a straight through, male to female cable. Connect the Enrollment

Station RF Interface AC adaptor to the power input and plug it into an available AC outlet. When the Enrollment Station RF Interface is turned on, the LED should light.

When the Enrollment Station sends data to the Enrollment Station RF Interface, the LED will momentarily turn off.
