Problems solved by technology

Due to the fact that the police system has been using dedicated line communication and the degree of business informatization is low, the foundation in network and information security management is very weak, there is no mature security structure as a whole, there is a lack of security standards and norms in management, and there is a lack of practice in application. Experience, the loss and disclosure of information is difficult to guarantee in practice or technology

Abstract

The embodiment of the invention discloses a block chain-based police information management method, a device, equipment and a medium. The method is executed by a blockchain node, and comprises the following steps: obtaining an operation record transaction request of police service data; executing the operation record transaction request based on a police affair intelligent contract deployed by a block chain so as to write the operation record of the police affair data into the block as transaction data; and updating the police affair knowledge graph according to the operation record of the police affair data written into the block. Through the technical scheme provided by the embodiment of the invention, systematic management of police information can be realized, and the accuracy and security of data are improved.

Description

technical field [0001] The embodiment of the present invention relates to blockchain data processing technology, and in particular to a blockchain-based police information management method, device, equipment and medium. Background technique [0002] With the development of computer and Internet technology, all walks of life are gradually realizing the management of electronic information, and the field of public security, or the field of police work, also has this demand. [0003] The existing informatization of the police field has the following problems: [0004] Information sharing is low. The information in the field of policing is characterized by various types, strong complementarities, and complex correlations. At present, most of the business application systems are operating independently and storing data independently, and the information system is networked and the degree of integration is low. [0005] Information accuracy cannot be guaranteed. Most of the e...
