Design And Implementation Of Examinee Certification System Based On The Watermarking Technology

At present, in the various social exam, the examinee information audit existenceviolate compasses operation behavior happens frequently, how accurate the examineeidentity certification and to prevent their stead, the phenomena of examinationmanagement departments at all levels need to carefully think about and is an urgentneed to solve the problem. The traditional examination authentication method is toverify the candidate’s id card and admission ticket, with the development of thecounterfeiting technology, the credibility of this authentication has become more andmore low, seriously affect the justice and fairness of the exam.Is feasible for using image authentication technology to solve these problems, byidentifying the integrity and authenticity of the image to ensure the safety of imagetransmission and storage has obtained rapid development in recent years, among them,the commonly used image authentication technology is the watermark technology.Watermark technology, in the examinee certification system, the examinee imageacquisition process, the use of image watermark anti-counterfeiting watermarktechnology, to ensure that the candidate’s information will not be tampered with.This study accords with the demand of the social exam examinee certificationmanagement, analyzes the development of examinee certification system based onwatermark technology background and significance, this paper expounds the necessityof system development. Papers on B/S architecture and C/S system structurecomparison, analyze the advantages and disadvantages of two kinds of architecture,and choose C/S system structure for the research and development architecture of thesystem. Papers on the concept, classification of watermark technology and basictheory has carried on the detailed introduction, put forward is applicable to theexaminee certification system of watermarking technology. At the same time, thepaper analyses the system development technology, determine the using c++andMFC framework for design and implementation of the system. Paper by adopting themethod of structured analysis and design, combining the actual demand of theexaminee certification management, the system has carried on the demand analysis,demand analysis, including feasibility analysis, watermarking authenticationalgorithm analysis, system function analysis and the data flow graph analysis and soon. On the basis of demand analysis, has carried on the detailed database design tosystem design and function, and by using the symmetric cryptographic technology toencrypt sensitive data in the database, to ensure data integrity, authenticity, andconfidentiality.Examinee certification system based on watermark technology provides examination management departments at all levels to provide a test platform for theeffective management ensures the fairness and justice. Designed and developed theexaminee of authentication system after testing, interface aesthetics, function perfect,basic has reached the expected goal.
