Authentication method and system

A method of authenticating users to reduce transaction risks includes indicating a desire to conduct a transaction and determining whether the transaction requires access to protected resources. Moreover, the method determines whether inputted information is known, determines a state of a communications device when the inputted information is known, and transmits a biometric authentication request from a server to an authentication system when the state of the communications device is enrolled. Additionally, the method includes validating the communications device, capturing biometric authentication data in accordance with a biometric authentication data capture request with the communications device, biometrically authenticating the user, generating a one-time pass-phrase and storing the one-time pass-phrase on the authentication system when the user is authenticated, comparing the transmitted one-time pass-phrase against the stored one-time pass-phrase, and granting access to the protected resources when the transmitted and stored one-time pass-phrases match.

Methods and systems for authenticating users

Encryption-based data access management may include a variety of processes. In one example, a device may transmit a user authentication request for decrypting encrypted data to a data storage server storing the encrypted data. The computing device may then receive a validation token associated with the user's authentication request, the validation token indicating that the user is authenticated to a domain. Subsequently, the computing device may transmit the validation token to a first key server different from the data storage server. Then, in response to transmitting the validation token the computing device may receive, from the first key server, a key required for decrypting the encrypted data. The device may then decrypt at least a portion of the encrypted data using the key.

Encryption-based data access management

A wear leveling method for non-volatile memory is provided, by which the non-volatile memory is substantially divided into a plurality of blocks and the blocks are grouped into a data area and a spare area. The method includes selecting a block based on an erased sequence when getting the block from the spare area. The method also includes performing a wear leveling procedure.

Wear leveling method and controller using the same

The invention discloses an access control system generated and verified on the basis of dynamic password and an identity verification method, belonging to the field of security certificate. The system comprises a user terminal for generating dynamic password and a certificate terminal for verifying dynamic password, wherein, the user terminal comprises a storage module which is used for storing arithmetic, keys and dynamic factors, and the certificate terminal comprises a reading module, a locker module and a certificate server module. The method of the invention comprises the following steps: after receiving an order sent by the certificate terminal, the user terminal generates dynamic password, the certificate terminal generates verified password according to stored arithmetic and key which are identical to the user terminal and corresponding dynamic factors, and the dynamic password and the verified password are compared to verify the validity and availability of the dynamic password of the user terminal.

Access control system generated and verified on the basis of dynamic password and authentication method thereof

The invention discloses a method and a system for identity authentication based on a dynamic password, belonging to the field of information security. The method comprises the steps that: when binding, a service terminal authenticates an account and a static password of a user, a third party authentication terminal authenticates the dynamic password of the user, if the dynamic password is correct, the binding between the account and a dynamic password token is successful, the service terminal establishes and stores the corresponding relationship of personal information, the account and the number of the dynamic password token, the third party authentication terminal establishes and stores the corresponding relationship of the personal information and the number of the dynamic password token; when the user logs in the service terminal, the service terminal authenticates the account and the static password of the user, the third party authentication terminal authenticates the personal information and the dynamic password of the user respectively, if the personal information and the dynamic password pass the authentication, the logging in is successful; otherwise, the logging in is failed. The system comprises: clients, the service terminal and the third party authentication terminal. The invention reduces cost and complexity of identity authentication performed by the user with the dynamic password and is easy to realize and convenient for operation and maintenance.

Method and system for identity authentication based on dynamic password

The invention is to solve issues: not security of transferring authentication cipher key through network by using plaintext; and managing bother, and high cost by using cryptograph format to transfer authentication cipher (AC). The disclosed method for updating AC remotely includes steps: server end calculates random seed and random number to generate verification data; server end carries out encryption operation for original AC and verification data, and transfers random seed and result of encryption operation to client end; information security equipment validates correctness of random seed; carrying out same encryption operation for random seed and original AC inside the information security equipment, and at server end so as to generate new AC, which is in use for updating AC inside the information security equipment, and database in server. The invention also discloses system for updating AC.

Method and system for updating certification key

The system includes interface at client end, authentication server, database, management server, and dynamic token containing individual information of user The method includes steps: dynamic token authenticates user ID; after authentication of user ID is passed, dynamic token generates dynamic cipher based on time/event factors and built-in individual information of user as well as combination with cipher key calculation; through interface at client end, user transfers dynamic cipher to authentication server; after receiving dynamic cipher, and obtaining individual information of user through calculation, the authentication server authenticates dynamic cipher In the invention, user only needs to input current generated dynamic cipher to carry out log on authentication so as to raise performance of easy to use in dynamic cipher authentication mode The invention also protects privacy of individual information of user

Dynamic cipher certifying system and method

The invention discloses an authenticating method and a system thereof, which relates to information security field and solves the problem that the user information is not safe in transaction process. The embodiment of the invention comprises that the server side receives user data information and a first dynamic password sent from the user side; the server side generates the first authenticating dynamic password according to the user data information; server side verifies the first dynamic password according to the first authenticating dynamic password and generates the second authenticating dynamic password after successful verification; the server side sends the second authenticating dynamic or the first password to the user side; the server side executes the transaction data in the user data information or permits the user to log on after using a third authenticating dynamic password generated by the server side to verify the user data information or the third dynamic password sent from the user side successfully. The invention enhances the safety of transaction for the user and prevents the user from loss caused by logging on phishing website by the user.
