Introduction
On-card biometric comparison provides a more secure biometric verification method than off-card biometric
comparison, as the comparison is executed inside the integrated circuit card (ICC) and the biometric
reference is never revealed outside the ICC. ISO/IEC 24787-1 specifies a set of requirements for implementing
biometric comparison inside the ICC. An ICC application that claims conformance to ISO/IEC 24787-1 fulfils
a set of requirements outlined in this document. The requirements are established for on-card biometric
comparison in both a sensor-off card and a Biometric System-on-Card, as defined in ISO/IEC 24787-1.

General principles and specifications
1 Scope
This document establishes conformance testing for the requirements described in ISO/IEC 24787-1, which are:

System-on-Card;
— security policies for on-card biometric comparison.
Measuring the performance of on-card biometric comparison algorithms such as error rates or speed is not

5 Test methodology
5.1 Test environment
Figure 1 and Figure 2 illustrate a typical test environment, which comprises a DUT and a test apparatus.
DUT is an ICC that is either a sensor-off-card device or a BSoC. Test apparatus is an IFD that sends command
messages to the DUT and receives response messages from the DUT. A DUT and a test apparatus are
connected by a physical interface that exchanges the messages. When a sensor-off-card device is evaluated
as a DUT, biometric samples are presented from a card holder to the test apparatus (see Figure 1). On the
other hand, when a BSoC is evaluated as a DUT, biometric samples are presented from a card holder to the
DUT (see Figure 2).

5.2 Test case
Each test case is introduced with the following information.
ID Introduces a unique test case identifier.
Version Specifies version number of the test case.
Purpose Specifies functionalities to be evaluated by this test.
Reference Introduces the references to the base requirements that bring this test case.
Introduces an ICC configuration profile to be tested, which is a set of specific features
Profile to be supported by the ICC. When the ICC does not support any of the features, this test
case is out of scope for evaluation of the ICC.
Precondition Specifies an internal state of the ICC to be transited before the scenario is performed.
Scenario Specifies test steps to be performed.
Expected result Specifies pass criteria for each test step of the test scenario.
Postcondition Specifies an internal state of the ICC to be transited after the scenario is performed.
An ID of each test case has a prefix label of test category which forms three digits of alphabet or number.
Test category is a set of test cases that is grouped by the same subject to be evaluated.
5.3 Test report
A test report shall be provided to analyse the detail of evaluation. The test report captures all test cases by
recording its ID. When a test case is applied to an evaluation, result of the test case is also recorded. Test
results are categorized into either "Pass" or "Fail". "Pass" is applied if the expected result of the test case
matches with all actual behaviours of the DUT and if the postcondition of the test case is fulfilled by the
actual internal state of the DUT after the scenario performed. "Fail" is applied if the expected result of the
test case does not match with any actual behaviour of the DUT or if the postcondition of the test case is not
fulfilled by the actual internal state of the DUT after the scenario is performed. The method to verify each
postcondition is not specified in this document since it depends on the specification of the DUT. If a test case
is not applied during evaluation because a DUT does not meet the profile of the test case, the test report will
record that the test case was not applicable.
6 ICC configuration profile
Each test case introduces an ICC configuration profile, which requires a specific feature list to be supported
by the ICC. All specific features to be used in this document are listed below:

8 Common test requirement
To avoid redundancy of description in relevant tests, the common test requirements are listed as below.
These requirements are referenced from the following relevant sections:
(1) Value of a biometric data DO is in a format as defined in ISO/IEC 7816-11.
(See ISO/IEC 24787-1:2024, 8.3.2)
(2) If PBO command is used for enrolment, re-enrolment, or verification with externally-
captured biometric data, the command data field forms either DO'7F2E' (see
Table 4), DO'7F60' (see Table 3), or DO'7F61' (see Table 2) to transfer the biometric data.
(See ISO/IEC 24787-1:2024, 8.4.1, 8.4.2)
(3) Regardless of the command, the biometric data is encapsulated in either a DO'5F2E' or DO'7F2E' if the
biometric data is transferred in a biometric information template DO'7F60' (see Table 3).
(See ISO/IEC 24787-1:2024, 8.3.1 Table 2, 8.3.2)
(4) All biometric data are enciphered for transmission to the ICC unless the trusted environment is
established to keep confidentiality including guaranteeing cardholders' privacy.
