Apparatus, method and computer program product for authentication

A method for authentication comprising:

• receiving an authentication request from a user apparatus;
• sending a verification code to the user apparatus, wherein the verification code comprises a combination of pattern codes and the pattern codes are associated with encrypted bio-patterns that the user has registered respectively;
• receiving first encrypted bio-information of the user corresponding to the verification code;
• and
• calculating a first encrypted deviation between the registered encrypted bio-patterns corresponding to the combination of pattern codes and the first encrypted bio-information.

An apparatus comprising

• at least one processor;
• and
• at least one memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
• receive an encrypted-deviation from an identity provider;
• operate on the encrypted-deviation;
• and
• determine authentication result based on the operation result.
