In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.
With the development of scientific technology and social economy, quick and effective automatic identity verification becomes more and more urgent in the field of security protection. Because the intrinsic attribute characteristics of the biological objects have strong self-stability and individual difference, the intrinsic attribute characteristics of the biological objects are ideal bases for identity authentication.
