Biometric key generation based on generated intervals and two-layer error correcting technique

作者：

Highlights：

• The bio-key is generated based on the feature distances between the minutiae and it will ensure a better security of the fingerprint data or template.

• The generated intervals can decrease the influence of the fingerprint intra-variation and improve the bio-key regeneration rate.

• The codewords obtained from the encoding of the generated intervals can implement the cancellability of the bio-key.

• The generated bio-key by our approach can be updated by changing the interval codewords.

• The two-layer error correction technique can detect and correct the random or unexpected errors and it will improve the reliability of the bio-key.

• Our bio-key generation approach has been practically experimented.
