BS ISO/IEC 19794-3:2006

The BS ISO/IEC 19794 standards are applicable to all identity management systems including:

• Identity document delivery and access management systems – such as border controls, corporate identity and access cards
• Prison access/egress
• Forensic identification - to identify casualties or suspects at the scene of a crime
• Citizens' rights - including voting, national health, unemployment benefits, driving licences
• Privileges associated with a particular employment category - including access to highly secure areas such as ports, airports, military establishments, company buildings, information systems
• Access to services - including banking services, financial services, and online purchases.

BS ISO/IEC 19794 will be used in access control and identification systems such as those based on smart cards or other recognition tools, and also applies to the storage of biometric identification data in corporate databases.

In the interest of implementing interoperable personal biometric recognition systems, this part of BS ISO/IEC 19794 establishes a data interchange format for finger pattern spectral data. The goal of this part of BS ISO/IEC 19794 is to allow the exchange of local or global spectral data derived from a fingerprint image without the exchange of the entire image. This will allow more compact data representations.

BS ISO/IEC 19794-3:2006 allows for representation of spectral components, such as Discrete Fourier Transform and (single-scale) Gabor Filter components, extracted from global or stationary (not image dependent and not varying over the image) local overlapping or non-overlapping uniform-sized regions of the original intensity (non-color) image. Some or all of the extracted spectral components will be stored in the data format, depending upon the implementation.

This part of BS ISO/IEC 19794 does not accommodate multi-scale (wavelet) decompositions.
