| Twenty-first Century is an era of rapid development of mobile Internet,smart phones are indispensable in people's daily life,and even become mobile office tools.This makes it possible for mobile phones to store large amounts of document files.Smart phones are becoming the next major hidden danger after computers and mobile storage media.It is because of the powerful function of the smart phone that more and more high-tech crimes are used,and the present form of secrecy is facing a severe test.The use of computer technology to carry out security check tasks is one of the important measures to enhance confidentiality.At present,the research on computer security technology check has matured and there are many computer security check tools on the market.However,the research on privacy check of mobile phones is still in its infancy,and there is no mature product for the time being.In order to make the secrecy work smoothly,the secrecy department urgently needs a confidential technical check tool for the mobile terminal,thus reducing the hidden danger of the smart phone.In this paper,the security check and monitoring system of the Android platform is studied and implemented.The system can check the security technology of the Android mobile phone,and monitor the application and image files installed in the Android phone.In this paper:(1)First we studied the technology of mobile phone forensics,file format recognition,file parsing and Android system data storage,and the confidential technical check functions of document files,address records,SMS,browser records and other data in the Android mobile phone are realized.(2)Based on the white list and the Accessibility Service in the Android system,the monitoring function of the application program is realized.Based on the broadcasting mechanism of the Android system and the OCR technology,the real-time monitoring function of the image file is realized.The final test results show that the security check function and real-time monitoring function of Android mobile phone are realized. |
