案件侦办中手机电子数据取证难点及解决方法

On the Difficulties in Mobile Phone Electronic Data Forensics in Case Investigation and the Solutions

手机电子数据对于部分公安机关案件侦办而言,既是重要的情报来源,也是事关侦办效果的关键证据。但在案件侦办实践中,存在着手机电子数据提取难、手机解锁难、数据恢复难以及手机权限root难等取证难点。经过反复试验与数据提炼,可以通过视频资料转换、JTAG方式提取、芯片剥离提取、物理绕过解锁、开机密码漏洞解锁等方式解决这些问题,从而助力公安基层技术人员的执法取证工作。

] In the case of case investigation conducted by the public security organs, mobile phone electronic data is both important sources of information and critical evidence of the investigation effects. There exist in case investigation practice difficulties in mobile phone electronic data forensics, mobile phone unlocking, data restoration, mobile phone permission root. After repeated experiments and data extraction, those problems can be successfully handled through conversion of video data, extraction in JTAG mode, chip stripping-based extraction, physical bypass unlocking, and power-on password loopholes unlocking, which, in turn, contributes to law enforcement forensics.of the technical personnel at the grassroots level of public security.[
