Research And Implementation Of Secrecy Inspection And Monitoring System For Android Platform

With the rapid development of mobile internet,smartphones have become an indispensable tool in today's life,and gradually become a platform of mobile office.For this reason,larger and larger amounts of documents are stored in mobile phones just like computers.However,smartphones are becoming the second source of leak following computers and mobile storage media.Therfore,the current form of secrecy is facing a severe challenge.Secrecy inspection is an important measure to strengthen the screcy work.As an effective mean to carry out the inspection of secrecy,secrecy technical inspection uses computer technology to carry out the secrecy inspection task automatically.For now,the research of computer secrecy technical inspection has developed a lot,and there are already many tools for computer secrecy technical inspection.However,the research of the secrecy technical inspection of mobile phones and related products are still in urgent needed.Secrecy departments are urgently need a secrecy technical inspection tool for mobile phones to reduce the hidden risk of smartphone leak and making the secrecy work smoothly.To solve this problem,a solution on secrecy inspection and monitoring system for Android platform is researched and implemented in this paper.This system could conduct secrecy inspection on the Android phone,as well as monitoring installed applications and image files in the Android phone.This system is a C/S architecture,divided into two parts:inspection-client and server management-side.Inspection-client is an Android application,and management-side is a B/S architecture.Inspection-clients should register the device on the management-side at the first installation.Then each subsequent secrecy technical inspection generates a report and uploads it to the server,and administrators can easily manage the devices and inspection reports in the server management-side.In this paper,the technology of mobile phone forensics,file format recognition,document parsing,full-text retrieval,word segmentation and data storage technology of Android system are researched.What's more,the feature of secrecy technical inspection for documents,contacts,SMS,browser records and so on were implemented,and the features of application monitoring and image file monitoring are implemented,the former feature is based on the whitelist and Accessibility Service in Android,the latter feature is based on the broadcast mechanism in Android and OCR technology.The final test results show that the secrecy inspection feature and monitoring feature for Android phone are successfully implemented,and the performance is consistent with routine secrecy insection.
