Abstract

The current digital era is full of digital devices and to ensure the safety of their data, users utilize the protective armor of passwords using the fingerprints lock, face lock, pin codes and password locks. The trial-and-error method possesses an infinite possibility of passwords in patterns/ pin locks for unlocking the devices. The levels of security ensure that only a limited number of trials are possible before any device blocks itself or makes unlocking harder. In these circumstances, especially when a victim is a deceased person (e. g. an abetment in suicide case), the password is practically impossible to attain through the authorities. However, the data can be retrieved with the unique and distinctive method of Chip-off analysis. In this study, a password protected mobile phone was retrieved from a deceased individual and only the analysis of his/her mobile could lead to investigative insights for catching the perpetrator. The Chip-off method has several difficulties and a password/ pin protected device increases the difficulties for analysis several folds. This study highlights the significance of chip-off analysis in achieving accurate importing and extraction of maximum data along with the use of the hardware/software, MSAB, XRY and other software.
用芯片法从密码保护的手机中提取数据——一个法医案例研究
当前的数字时代充斥着数字设备,为了确保数据的安全,用户使用指纹锁、人脸锁、pin码和密码锁等密码作为保护盔甲。这种试错法拥有无限可能的密码模式/ pin锁解锁设备。安全级别确保在任何设备阻塞或解锁困难之前,只能进行有限次数的试验。在这些情况下,特别是当受害者是死者时(例如自杀案件中的教唆),密码实际上是不可能通过当局获得的。然而,数据可以用独特的和独特的方法来检索。在这项研究中,一个密码保护的手机从一个死者身上找回,只有对他/她的手机进行分析,才能找到抓捕肇事者的调查见解。芯片脱落方法有几个困难,密码/ pin保护装置增加了分析的难度几倍。本研究强调了芯片分析在实现准确导入和提取最大数据以及使用硬件/软件、MSAB、XRY和其他软件方面的重要性。
