Description / Abstract:
This part of ISO/IEC 19794 specifies data interchange formats
for signature/sign behavioural data captured in the form of a
multi-dimensional time series using devices such as digitizing
tablets or advanced pen systems. The data interchange formats are
generic, in that they may be applied and used in a wide range of
application areas where handwritten signs or signatures are
involved. No application-specific requirements or features are
addressed in this part of ISO/IEC 19794.
This part of ISO/IEC 19794 contains
– a description of what data may be captured,
– three data formats for containing the data: a full format for
general use, a compression format capable of holding the same
amount of information as the full format but in compressed form,
and a compact format for use with smart cards and other tokens that
does not require compression/decompression but conveys less
information than the full format, and
– examples of data record contents and best practices in
capture.
Specifying which of the format types and which options defined
in this part of ISO/IEC 19794 are to be applied in a particular
application is out of scope; this needs to be defined in
application-specific requirements specifications or application
profiles.
It is advisable that cryptographic techniques be used to protect
the authenticity, integrity, and confidentiality of stored and
transmitted biometric data; yet such provisions are beyond the
scope of this part of ISO/IEC 19794.
This part of ISO/IEC 19794 also specifies elements of
conformance testing methodology, test assertions, and test
procedures as applicable to this part of ISO/IEC 19794. It
establishes test assertions on the structure and internal
consistency of the signature/sign time series data formats defined
in this part of ISO/IEC 19794 (type A level 1 and 2 as defined in
ISO/IEC 19794-1:2011/AMD 1), and semantic test assertions (type A
level 3 as defined in ISO/IEC 19794-1:2011/AMD 1).
The conformance testing methodology specified in this part of
ISO/IEC 19794 does not establish:
– tests of other characteristics of biometric products or other
types of testing of biometric products (e.g. acceptance,
performance, robustness, security),
– tests of conformance of systems that do not produce data
records claimed to conform to the requirements of this part of
ISO/IEC 19794.
