User permission data encryption and decryption method for construction engineering material management system

Abstract

The invention relates to a user permission data encryption and decryption method for a construction engineering material management system, and solves shortages in the prior art. The technical scheme comprises the steps of: (1), establishing the construction engineering material management system composed of a foreground website, a permission management system, a real name authentication module, a credit extension module and an accounting module, wherein the foreground website, the permission management system, the real name authentication module, the credit extension module and the accounting module are connected through a network; and a unique identifier is given to web layer interfaces of the foreground website, the permission management system, the real name authentication module, the credit extension module and the accounting module in a unified manner; and (2), defining a request access permission item of resources in the construction engineering material management system as a job role, and defining multiple job roles as a high-permission job, so that nested permission definition satisfying service requests of various jobs is formed. By means of the user permission data encryption and decryption method for the construction engineering material management system disclosed by the invention, the fact that visitors at various key nodes have own permissions can be ensured; and thus, falsification of data is difficult.

Description

technical field [0001] The invention relates to a method for encrypting and decrypting authority data in a construction engineering material management system, in particular to a method for encrypting and decrypting user authority data in a construction engineering material management system. Background technique [0002] At present, in China, the construction industry is a pillar industry. The process management of the construction industry is a difficult point in my country's construction management. In the construction industry, the required construction project funds are high, the construction cycle is long and the capital recovery is slow, and construction material suppliers are involved. The degree is high, and in the whole project practice, advance payment is a common phenomenon. The current capital market only assists in lending for investment in construction projects as a whole, but cannot provide reasonable and effective assistance to the material vendors involved i...
