Background technology
Identity real name certification is the process utilizing the proprietary Verification System having information of registered users the individuality wanting to conduct interviews to be carried out to the judgement process of identity.System of real name authentication is to provide the certification to system access person true identity, is mainly used in stoping unauthorized user to the access of system resource.Generally with electronic technology, biotechnology or electronic technology and the authenticity of biotechnology in conjunction with Certificate Authority user identity.Divide from the relation of certification voucher used and user, authentication can be divided three classes: certification known to user, user hold mark certification and user biological feature verification.
Conventional identity real name authentication techniques mainly contain the combination of following a few class or wherein a few class:
1. carry out certification by known things
Knowledge based engineering method determines one's identity.Such as: password and PIN code, the password of user's use and the confidentiality of PIN code are the necessary guarantees carrying out authentication that can be safe.
2. carry out certification with the article had
Method based on password board determines one's identity.Such as: user various can prove the certificate of identity, passport, smart card (Static and dynamic), digital certificate, USBKey certification or identity card etc.The shortcoming of this method is when accidentally losing when token or copied by malicious person and usurp, just cannot the stability of guarantee information system and fail safe.
3. the certification of identity is carried out by itself distinctive feature biological
Method based on biological characteristic determines one's identity.Biological characteristic for certification generally has palmmprint, fingerprint, face and iris etc.The generality of biological characteristic, consistency and irreplaceability all make the system utilizing biological characteristic to carry out certification have high security and high security.
