The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention. In the drawings:
FIG. 1 is a schematic diagram of a public security data management architecture;

Detailed Description
As shown in fig. 1, a block chain-based public security data management platform and method are provided, the block chain-based public security data management schematic diagram includes modules for scene construction, policy construction, data system ecological construction, and pain point difficulty solving. Are all built on the basis of block chains.
The blockchain technology is defined to be capable of transmitting trust in a digital world and ensuring information security in the network era. The decentralized and distributed network structure of the block chain improves the anti-attack capability of the network, but the block chain technology is not necessarily suitable for all public security data management. Some data resources of the public security department are suitable for adopting a central database, such as news information, notification and the like, but some data resources are more meaningful by utilizing a distributed block chain storage structure. Information management of the public security department can establish a alliance chain mode of the public security related department for realizing safe sharing of a plurality of departments, and can register members of a block chain by limiting and set read-write permission of member nodes on the block chain. The allowed nodes can participate and view the chained data, and all nodes cannot tamper the chained data, so that the data consistency and the secure exchange are effectively guaranteed.
As shown in fig. 2, the public security data management platform includes a service layer, a management layer and a network layer; the service layer comprises an information sharing query, an associated query, an access control, a data maintenance, a data synchronization and registration block chain, and is used for providing a data operation interface for a user and realizing the functions of data sharing, query and data maintenance; the management layer comprises a consensus mechanism, an encryption algorithm, a mining module and an intelligent contract and is used for achieving consensus through mining in the peer-to-peer network through encryption, verification and signature and meeting the requirement of the contract for realizing linkage of blocks of citizen information management; the network layer includes distributed storage and databases for information dissemination over the P2P network.
As shown in fig. 3, the information management related to citizens by the public security department involves multiple departments, which require information sharing and also perform dynamic update. And through the form of a alliance chain, related departments are allowed to register in the blockchain, corresponding authorities of the departments are authorized, a consensus process for blockchain calculation is participated, and each piece of block data generation is completed by the specified budget nodes together. And other nodes which are not authorized to write data can perform information query, but do not need to participate in the consensus process, so that data sharing can be met, and data can be prevented from being tampered. The selection of the advanced nodes can comprise relevant departments such as entry and exit management, key personnel management, social security management, case and event management and the like, and can provide more perfect, accurate and safe population files for citizen information management.
The service of the public security integrated information management system is divided and coded according to three levels of service domain, service activity and service operation, the service domain refers to the division of basic service types and ranges of an organization, the service activity is the whole of one type of closely-related management activity in the service domain, and the service operation is the basic and irreparable minimum functional unit in the service activity. The structure is shown in fig. 4. The 1 st to 2 nd bits are service domain codes; the 3 rd to 4 th bits are service activity codes; bits 5 to 6 are the service operation code. For example, the following steps are carried out: the business operation name 010206,01 is population management, 02 is resident identification card management, and 06 is resident identification card issuance.
The recording and verification process of the information data of the public security is shown in fig. 5. The method comprises the following steps:
the method comprises the following steps: generating a new data record;
step two: data record transactions are propagated through a public security P2P network;
step three: verifying the data;
step four: propagating the verification result through the network;
step five: new data is written into the blockchain.
In the system, the recording of the blocks is performed by a specific node in a polling mode. And other nodes verify the newly recorded data through local data records of the other nodes, and the verified data is propagated in the whole network.
The invention analyzes the pain point of the public security data management from the angle of the data information chain, and how to solve the pain point by the block chain technology is finally applied to the public security data management.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
