(54) Title: SECURELY PERFORMING CRYPTOGRAPHIC OPERATIONS 
(57) Abstract: Disclosed herein are methods, systems, and apparatus, including 
computer programs encoded on computer storage media, for securely performing 
/ cryptographic operations. One of the methods includes receiving biometric infor
RECEIVE CRYPTOGRAPHIC 202 mation associated with a user and a request to perform one or more cryptograph
OPERATIONREQUEST ic operations based on one or more cryptographic keys stored in a memory of an 
identity cryptographic chip (ICC); comparing the biometric information associated 
RECEIVEIDENTITYI NFOI204 with the user with biometric information pre-stored in the memory of the ICC as pre-stored biometric information; and in response to determining that the biometric 
information matches the pre-stored biometric information, authorizing the one or 
206 more cryptographic operations to be performed.
