the identity information updating module is used for receiving a student identity information updating instruction, wherein the student identity information updating instruction comprises updating content, calling the student identity information in the target block, generating an updating target block according to the student identity information and the updating content, and covering the target block by the updating target block;
wherein, the identity information block screening module comprises: the real information first judgment unit is used for calling the real information which is automatically bound by the generation management node, the real information is a school institution name, whether the real information belongs to school information or not is judged, and if not, verification is not passed; if yes, executing the step in the second real information judging unit; the second real information judgment unit is used for judging whether the called real information is subjected to credit authorization of a registration authentication mechanism, and the registration authentication mechanism is used for performing credit authorization on the real information bound to the nodes in the block chain; the identity information block retaining unit is used for passing the verification when the real information is authenticated by the credit granting unit, or not passing the verification, and retaining the identity information block passing the verification;
wherein the target block generation module comprises: the identity information classification unit is used for classifying all the called student identity information according to respective generation management nodes; the generating time marking unit is used for calling the generating time of the identity information block corresponding to each student identity information and marking the generating time on each student identity information; and the target block generation unit is used for reserving the student identity information with the latest generation time in each class, integrating the reserved student identity information and then generating a target block, wherein the target block records the learning information of each stage of the student.
5. The system of claim 4, further comprising an information authentication module, wherein the information authentication module specifically comprises:
the information key sending unit is used for sending the information and the key in the target block to the generation management node passing the verification;
and the authentication recording unit is used for receiving the authentication passing information of the generation management node and recording the real information corresponding to the authenticated node in the target block.
6. The student identity information processing system in the blockchain network according to claim 4, wherein the system further includes a verification module, when the generation management node receives the blockchain information retrieval request, the verification module verifies the real information of the sending node of the blockchain information retrieval request and the basic information of the target user, and sends the retrieval key after the verification is passed.
