The invention discloses a secret key lock making method, which comprises the following steps: in order to collect multiple stable biological characteristics, biological characteristics and stability of a code mapping and stored as sets of code on biological characteristics; input multiple stable biological characteristics on biological characteristics of the cipher code input key system to compile, generate passwords and the corresponding key lock. The stable biometric feature may be a fingerprint information. The confidentiality of confidential performance, biological characteristics and biological characteristics of fingerprint code through the stable only set the code string key with biological characteristic and uniqueness of the default mapping confidentiality and code string combination, also has three security so as to obtain high security performance. The invention also discloses a key with high confidentiality, which comprises a code string, a stable biometric information corresponding to each code of the code string, and a mapping array for stabilizing the biometric information and the code. The invention also discloses a security system with high secrecy performance.
