The invention provides an identity authentication method, device and system. The method comprises the steps: that an interaction end receives an interaction instruction initiated for a user, and obtains the identity information of the user; the interaction terminal sends an identity recognition request to the server; wherein the identity recognition request comprises the identity information; wherein the identity recognition request is used for indicating the server to match the identity information with standard identity information of candidate users corresponding to the interaction terminalso as to determine a user account corresponding to the user, and the user account is used for responding to an interaction operation corresponding to the interaction instruction; wherein the user near the interaction terminal is marked as a corresponding candidate user by the server. According to the technical scheme, the identity recognition efficiency and recognition accuracy of the user can beimproved, and the interaction efficiency and safety can be improved.

The present invention provides a message sending method for an application server, which includes: receiving a locally sent message; obtaining an interactive user identifier corresponding to the local user identifier according to a local user identifier corresponding to the locally sent message; In the group information, the group unique identifier of the corresponding message interaction group is acquired; based on the group unique identifier and the interaction user identifier, the local sending message is sent to other users in the message interaction group. The invention also provides an application server message receiving and interaction method and an application server message sending, receiving and interaction device. The application server message sending, receiving, and interaction method and device of the present invention realize instant message interaction between application terminals of the heterogeneous application servers by setting a common message interaction group among the heterogeneous application servers.

The invention discloses a method for enhancing human-computer interaction security, which comprises the following steps of: packaging user input messages into messages of a uniform format according to types and parameters of the user input messages; adding the packaged messages into a globally unique message queue and processing the messages one by one with message loops; checking the validity and legality of the messages in the processing; and making different security decisions according to checking results and performing journal recording on the checking process and the checking results. The invention also discloses a system for enhancing the human-computer interaction security, which comprises a uniform message format module, a message loop module, a message checking module and a message decision-making module. The method and the system have the advantages of effectively putting an end to malicious or illegal operation in a human-computer interaction process and enhancing the human-computer interaction security.

The invention discloses a method for verifying interaction. The first interaction password may be generated by the first device using information about the first party to the interaction and the second party to the interaction. The second interaction password may be generated by the second device also using information about the first party to the interaction and the second party to the interaction. Verifying each password verifies that the details of the interaction have not been altered and that both the first and second parties have legitimately authorized the interaction.

A serially reconfigurable variable stiffness robot joint structure based on permanent magnet springs, comprising a base, a rope, and a variable stiffness motor; one end of the vertical base of the base is processed into a waist-shaped blind hole, and the other end is processed with a waist-shaped blind hole. The upper through hole and the lower through hole are connected by the blind hole. The shaft I is installed in the lower through hole through the bearing. One end of the shaft I is connected with the reducer and the position servo motor in turn, and the other end is located in the waist-shaped blind hole. A small pulley is installed. ;In the upper through hole, the cross roller bearing I and the shaft body of the output disc are rotated and installed, and the end face of the cross roller bearing I is fixedly connected with one end of the disc of the output disc, and the shaft body of the output disc is located in the waist-shaped blind. A large pulley is installed in the hole, a synchronous belt is installed between the large pulley and the small pulley, and the disk of the output disk is connected with the connecting rod disk and the variable stiffness device in turn through the crossed roller bearing II. The variable stiffness device changes the stiffness adjustment range by quickly adjusting the permanent magnet spring and rope arrangement, and has a wider range of applications.

The present application relates to a method, device, computer equipment and storage medium for determining the distribution of data tags. The method includes: obtaining the tag ciphertext information sent by the tag side device after performing homomorphic encryption processing on the sample tags corresponding to multiple sample IDs; obtaining The initial binning information corresponding to the sample feature set, the sample feature set includes the sample features corresponding to multiple sample identifiers, the initial binning information includes the initial binning corresponding to each sample feature; each initial binning information is obtained based on the tag ciphertext information and the initial binning information Initial ciphertext statistical information corresponding to binning; obfuscate each initial ciphertext statistical information to obtain the target ciphertext statistical information sequence; obtain the target decryption statistics returned after the label device performs homomorphic decryption on the target ciphertext statistical information sequence The information sequence restores the target decryption statistical information sequence to obtain the initial label distribution information corresponding to each initial binning. By adopting the method, the security of data interaction can be improved.
