BS ISO/IEC 19794-7:2021

What is ISO/IEC 19794-7 about?  

ISO/IEC 19794-7 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.  

ISO/IEC 19794-7 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 convey less information than the full format 
• An XML schema definition 
• Examples of data record contents and best practices in capture 

Who is ISO/IEC 19794-7 for? 

ISO/IEC 19794-7 on biometric data interchange formats is useful for: 

• Forensic laboratories 
• Criminal Police Institutions 
• Law enforcement department 
• Healthcare department 
• Civil identification department 

Why should you use ISO/IEC 19794-7?  

 ISO/IEC 19794-7 is advisable that cryptographic techniques be used to protect the authenticity, integrity, and confidentiality of stored and transmitted biometric data. 

ISO/IEC 19794-7 specifies elements of conformance testing methodology, test assertions and test procedures as applicable. 

ISO/IEC 19794-7 establishes test assertions on the structure and internal consistency of the signature/sign time series data formats.
