ePassport Security Mechanisms
The Document Security Object (SOD) is a digital signature of the contents of the ePassport (or MRTD)
and is generated by the issuance agency. The SOD is stored within the ePassport and can be authenticated
to prove that the document is authentic and unaltered. There are several levels of security mechanisms
available:
•
Passive Authentication
(mandatory): Proves that the contents of SOD and stored information are
authentic and not changed. It cannot protect against perfect duplications of the IC or IC
substitution.
•
Active Authentication
(optional): Prevents copying SOD, authenticates IC, and proves that IC
and physical passport belong together. It can ensure that the IC is legitimate and issued by the
country claimed.
•
Basic Access Control
(optional): Prevents skimming, eavesdropping, and misuse. The e-
Passport cannot be read by an electronic reader until the machine-readable zone is read first.

ICAO Viewer Operation
After opening the application, follow the instructions in the
dialog box at the bottom of the main screen, and wait for the
Scanner and ICAO engine to activate. The initialization is
complete when the dialog box reads, “
Please Insert Card
(Scan Manual Mode)
”. Shown in the adjacent figure is the
main screen.
Note that the
ICAO Viewer
application has a tab driven user
interface. By selecting various tabs, a user can access different
information, or can change various configuration options.
Insert an ePassport to be scanned and decoded. You may need
to press “F4” to restart the scanner module if it has time out
and powered down. The power down mode is indicated by the
status bar at the bottom of the display being colored orange.
After the passport is inserted, an optical scan is initiated. The
first operation that is performed is to decode and display the
MRZ data. Once this is successfully performed, the unit beeps
once and the MRZ data is displayed at the top of the main
window.
The next step is to begin reading the smart card IC. A dialog
box will display the incremental status, and show a progress
bar as the data is being read.
