Information technology - Biometric data interchange formats - Part 7: Signature/sign time series data

ISO/IEC 19794-7:2021 This document 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 can 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 document.

This document contains:

- a description of what data can be captured;

- three binary 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;

- an XML schema definition; and

- examples of data record contents and best practices in capture.

Specifying which of the format types and which options defined in this document are to be applied in a particular application is out of scope; this needs to be defined in application-speci
