Identity information authentication method, server, client and system

The invention provides an identity information authentication method, a server, a client and a system, and the method comprises the steps: enabling the server to determine whether a login request passes the authentication or not according to a second public key, a user name, a first client timestamp and a first short-time token of the client after receiving the login request of the client; if thelogin request passes the authentication, feeding back a newly generated second short-time token to the client, and generating the first short-time token and the second short-time token according to the user identity information, the equipment fingerprint information and the corresponding random number, wherein the client carries the second short-time token when the client sends the service request; if the server determines that the service request passes the authentication, determining the operation authority of the client according to the predetermined security trust degree of the client, andprocessing the service request according to the operation authority. In the scheme, the server generates the short-time token through the equipment fingerprint information, the short-time token is refreshed after login authentication is passed, and the operation authority of the client is determined through the security trust degree, so the communication security is improved.

Secure communication method based on multichannel signal fragmentization transmission technology

The invention discloses a secure communication method based on multichannel signal fragmentization transmission technology. The secure communication method comprises the following steps: dispersing communication data into small fragments in an information transmitting terminal, and then transmitting the small fragments by multiple information channels according to a certain rule; and receiving fragmentization data transmitted by the multiple channels in an information receiving terminal, and integrating the fragmentization data according to the fragmentization rule when the information is sent to obtain complete data transmitted by the transmitting terminal. The dispersion and integration rules of the fragments are determined by keys in the transmission process. By adoption of the secure communication method provided by the invention, on one hand, the difficulty of a third party to intercept complete information from the communication data can be greatly increased, so that the third party is difficult to crack signals via ultrahigh performance calculation; and on the other hand, even if enough information is intercepted by the multiple channels, complete effective data is difficult to be extracted from the encrypted fragmentization information, and it is difficult to recombine and recover the original data, therefore the security is improved.

Document encryption/decryption method and apparatus based on iris recognition and authentication

The present invention proposes a document encryption/decryption method and apparatus based on iris recognition and authentication. The method comprises: collecting an iris image of a user, generating iris feature data after analyzing and processing the iris image, and registering the iris feature data into an iris information feature library; encrypting a document by using the iris feature data as a key; and after it is detected that the document is requested to be decrypted, determining whether a living body iris image is collected, if so, carrying out feature extraction on the living body iris image, acquiring iris feature data corresponding to the living body iris image, comparing the iris feature data of the living body iris image with the iris feature data corresponding to the document in the iris information feature library, and if iris feature data of the living body iris image are consistent with the iris feature data corresponding to the document, then decrypting the document, otherwise, prompting that the decryption fails. According to the document encryption/decryption method and apparatus based on iris recognition and authentication, the iris image with uniqueness can be used to carry out identity recognition, thereby triggering an encryption and decryption algorithm to realize security management for the document.
