Design And Implementation Of Moblie Digit Evidence Manage System Base On Android

With the development of information technology,the mobile device can generate different types of multimedia which can be used as evidence in some cases.But digital content is vulnerable to tampering and attacks,therefore,to design a collection and management system of electronic judicial evidence can be used to provide strong protection and support.This system is designed and implemented based on B/S and Android electronic judicial evidence management system in integrated mode.This thesis first researched currently situation of electronic evidence using and studying,then analyzed the insufficient in electronic evidence processing technology;secondly for the key problem existing in electronic evidence collection process and comparing process,this thesis proposed has based on intelligent points block of break-point continued biography program,to adapted mobile end of complex network situation,proposed a chaos sequence encryption of watermark embedded and detection algorithm to solve the electronic evidence information fixed and using of compare problem;then analysis of electronic evidence management system based on Android’s business needs and design and build database systems,on a demand basis,description of major sections of the system module design and realization method after the final completion of the project,according to the theory of software test in software engineering,designing various inputs to test total software modules which contains some functions of the system.The procedure of mobile electronic evidence management system research and development using parallel development of Web front-end based on Android platform,and the whole Android application were tested in various mobile devices and the results testified the correctness,the Service applications were programmed based on ASP.net Framework which make the service robust.Test results with the actual operation of the show that better meet the actual needs of the project,improving the efficiency and reliability of electronic evidence.
