Design And Implementation Of Privacy Information Masking Algorithm

Privacy information masking plays an indispensable role in solving the privacy problem in today's society,but the traditional masking methods still have problems,and new methods will be adopted to solve this problem in the paper.The privacy information masking system introduced in this paper is an ink privacy information masking system based on nocenter password.This system is designed to solve the problem of fixed and centralized rules in traditional privacy information masking system,and to solve the problem of modeling the traditional privacy information masking system through primary and external keys.Cost of data consistency after masking.The core of the system is to replace the traditional strong consistency algorithm with the block chain idea "consensus",and to construct the corresponding ink code book by referring to the relevant cryptography and security technology.The purpose of the system is to realize the design defects of data consistency after the traditional privacy information masking algorithm can not guarantee the data consistency in a single library.The ink privacy information masking system can support multitask parallel masking,multidatabase channel,multithreading privacy information masking conversion and automatic batch management of multiple privacy information masking conversion tasks in the process of privacy information masking.A unified management platform for source privacy information data and a privacy information masking system composed of multiple task nodes support multiple systems to share a set of ink code book for consistency masking of privacy information data.Furthermore,the privacy information masking system supports incremental masking and records the last incremental operation.It can carry out corresponding masking incremental regression,and realize automatic scanning,automatic identification and automatic matching of the privacy information masking system.The ink system can not only ensure the efficient use of information data,but also ensure the privacy and security of information data.The main work of this paper is as follows: Firstly,an ink algorithm is designed and implemented,which can maintain the data consistency of masked information in a single database without the help of corresponding data modeling,and solve the design problem of traditional privacy information masking.Secondly,a distributed masking algorithm is designed and implemented.In the early stage,load balancing analysis is carried out on data allocation to determine the partition of masking tasks,and crossdomain resource database is built to form a distributed node which can perform masking operation independently.Thirdly,a masking system of ink privacy information based on ink algorithm is designed and implemented,which realizes the masking function of basic privacy information and verifies the effectiveness of ink algorithm and distributed masking algorithm.
