Two-party distributed SM9 digital signature generation method and system

The invention discloses a two-party distributed SM9 digital signature generation method and a two-party distributed SM9 digital signature generation system. In the method, a KGC generates a corresponding private key for two communication parties A and B participating in an SM9 digital signature, and the party A sends a signing request to the party B after a signing key is received. The party B selects random numbers k1, k2 which belong to [1, q-1], computes [mu]1=g1<k1> and [mu]2=g<k2>, and returns [mu]1 and [mu]2 to the party A. At the moment, the party A randomly selects k3 and k4, computesa first part h of the signature, and returns h'=k4-h(modq) to the party B. The party B computes s1 and s2 by using the own private key and sends s1 and s2 to the party A. After receiving s1 and s2, the party A uses the own private key to compute a second part S of the signature, and after verification of the signature is passed, the party A publishes the complete SM9 digital signature (h, S). Themethod and the system provided by the invention have the advantages of being high in security and execution efficiency and prone to verify; during a digital signature generation process, the SM9 digital signature can only be generated in a distributed manner under the condition that the two communication parties participate in jointly, the signature sub-key can be effectively prevented from beingstolen by external attackers and counterfeiting of internal participators can be effectively avoided, and generation security and fairness of the SM9 digital signature the two parties participate in are improved.

Online safe payment system based on handwriting authentication

Provided is an online safe payment system based on handwriting authentication. The system comprises a 101 user registration module; a 102 reception module; a 103 learning and training module; a 104 authentication module, and a 105 payment module. The 102 reception module is used to receive any to-be-identified signature sample input by a user, perform multi-feature fusion to use various attribute characteristic values as the characteristic values of the sample, excavate contribution degree of each attribute characteristic value on correct identification of the signature, perform descending sort, and select a group of optimal weights according to contribution value rank ordering to fuse various characteristics. The 103 learning and training module converts the combined multi-feature set to data of 1 to 8, and the data is used as input based on a neighbourhood-hypernetwork sorter, so as to perform training and tests. A user inputs a signature, and the 104 authentication module compares a to-be-identified hyperedge with hyperedges in a hyperedge library to authenticate authenticity of user handwriting. The 105 payment module applies the handwriting authentication to online safe payment. The system has higher stability, security, and convenience. The system combines with a multi-feature fusion technology, and can improve identification efficiency and accuracy of signature samples.

Payment method, payment system, novel POS machine and payment core system

The invention provides a payment method and a payment system which support payment verification of a virtual account. According to the invention, a user does not need to carry an IC card, the user is prompted to adopt different payment verification modes according to the amount money to be paid, payment verification data inputted by the user and a serial number of the current payment are sent to a payment core system, and the payment core system is enabled to perform verification according to account opening information inputted by the user when the account is opened. For large-amount payment, the user is prompted to sequentially input fingerprint data, a password and head portrait information, and the payment security of the user is improved; and for small-amount virtual account payment verification, the user is prompted to sequentially input fingerprint data and a password, and small-amount fast payment is realized. The invention further discloses a novel POS machine which further provides a fingerprint input function and a picture taking function while supporting traditional password input, takes a picture for the user when the user performs payment so as to be used for large-amount payment verification or act as a payment record of virtual account payment verification, thereby being convenient for acting as unauthorized payment evidence when unauthorized payment occurs in a later period.

Method for controlling access to visual media in a social network

A method for controlling access to a visual medium in a social network comprising user units connected to a social network site server associated to a database and a to a distorted visual medium server storing visual media posted by users of the social network. A visual medium is selected by a posting user on a user unit and made available to at least one entitled user of said social network. The posting user defines a list of entitled users to be entitled to access the visual medium, said list of entitled users comprising at least one identifier identifying at least one entitled user, said identifier being associated to a parameter defining an access level to the selected visual medium. The selected visual medium is uploaded to the distorted visual medium server in association with the list of entitled users. The distorted visual medium server stores the visual medium in a memory and applies a distortion effect so as to obtain at least one distorted visual medium degraded according to a predefined degradation level. An entitled user iden tified on the list receives, from the distorted visual medium server, the visual medium distorted according to a degradation level corresponding to the parameter defining the access level associated to the identifier of the entitled user. The distortion effect applied on the original visual medium preferably consists of a scrambling operation performed on the original visual medium to obtain a scrambled visual medium. The access level defines the rights of a user for descrambling the scrambled visual medium into a reconstructed visual medium. Depending on the user access level, the reconstructed visual medium can be a partially descrambled visual medium or a fully descrambled visual medium according to the user access level.

Non-motor vehicle parking and fetching system based on human face identification

The invention discloses a non-motor vehicle parking and fetching system based on human face identification. During non-motor vehicle parking, a human face identification module collects human face information and storing the information to a storage module; a control module controls a parking pile to open; after a user parks the non-motor vehicle and confirms the state, the control module controls the parking pile to close; a charging module starts to charge according to time; during non-motor vehicle fetching, the control module gives a signal collection order to the human face identification module; the human face identification module collects human face information and transmits the information to a comparison module; the comparison module and the storage module conduct information matching and then send the matching result to the control module; if the information is matched, the charging module displays charge fares and charges; and after the user pay the charge, the control module controls the parking pile to open and non-motor vehicle parking and fetching service is finished. Each system operates independently and a server is unnecessary, so low cost is required and safe and convenient vehicle parking and fetching service can be provided for non-motor vehicles of a user; and problems of casual parking and loss of non-motor vehicle can be solved.
