Background
The personnel management comprises affair work, and also comprises thought construction, political construction, organization construction, wind making construction, system construction and the like of personnel. All levels of organizations need to be responsible for development and management of personnel, develop learning and education work of the personnel, develop activities, supervise and investigate and evaluate the cadres of the personnel, and thus, a powerful basic staff team is built.
The traditional management is based on paper documents, information is scattered, and storage, tracing, auditing and analyzing are difficult. An organization may have thousands of people, each of whom has several related activities each month, and if all people are stored in the form of paper documents, the cost and the workload are huge, and the follow-up tracing and auditing of the complete authenticity of the information are difficult. When the assessment and evaluation are carried out on personnel and basic level organization afterwards, the completeness and reality of information cannot be determined, and whether the situation that documents are scattered or supplemented afterwards exists or not can not be determined.
A cloud platform based digitizing system, such as patent CN110347677A, digitizes information recorded on paper documents and stores the information in a centralized database. This approach can solve the problem of difficult information storage, but centralized management still has drawbacks. Especially when a plurality of units are involved, each unit adopts different digitalization systems, the information formats are not uniform, and the record verification, the record tracing and the record auditing are still inconvenient.
The block chain technology has the characteristics of multi-party cooperation, verifiability, auditability, traceability, non-tampering and the like. Through the technologies of digital signature, consensus algorithm and the like, a trust mechanism can be established and the confirmation and consensus of information can be achieved in an information system involving multi-party participation without depending on a specific central agency or a third party agency. Compared with the traditional centralized information system based on a centralized database, in the information system based on the block chain, once the data is uplinked, the data cannot be tampered and deleted, the data can be traced and audited more easily, and the centralized information system based on the block chain has more public trust. By means of characteristics of decentralized, non-tampering, clear tracing, easy auditing and the like of the block chain, information management can be improved to a new height.
