Abstract (in Japanese) (See Japanese page) 
(in English) In the field of online biometric authentication, there are some issues for convenience and security, for example, biometric feature data reduction, speedy identification, and safety of registered biometric data. To solve these issues, it is expected to be used biometric template protection schemes.
These schemes use biometric bit-strings feature generated by biometric feature data to authenticate, therefore, in terms of security, there is a new problem that it is insufficient of information entropy to use cryptographic primitives.
In this work, we evaluate the statistical test for bit-strings generated by face image, and additional test of pseudo-randomness.
In the results of tests, we reveal that the biometric bit-strings feature includes the deviation of Bit-aliasing caused by biometric bias.
