1.0 Collection of electronic evidence from computers 从计算机收集电子证据
从计算机上专业地获取证据有几种方法。首先是破译。它是通过使用一定的技术手段对加密信息进行解密，以获取和理解作为电子证据的信息。其次是测试。在收集电子证据的过程中，如果涉及到与软件设计或使用有关的问题，专业人员应使用预先制作的测试文件对特定软件进行现场测试。本测试的基本目的是验证软件的正确性、完整性和安全性。第三是复苏。对于硬盘、服务器硬盘和软盘、移动硬盘、USB或可存储光存储设备中丢失的电子数据，需要利用电子数据恢复技术进行抢救和恢复。四是拦截。计算机系统在使用过程中也可能发生电磁泄漏，这些泄漏的电磁信号可能包含一些重要信息，因此相关的电子数据也可能被某些技术手段截获。
There are several ways to professionally obtain evidence from computers. First is deciphering. It is by using certain technical means to decrypt encrypted information to obtain and understand the information as electronic evidence. Second is testing. In the process of collecting electronic evidence, if it involves problems related to the design or use of software, professional should use pre-produced test files to test specific software on-site. The fundamental purpose of this test is to verify the correctness, completeness and security of the software. Third is recovery. It needs to use electronic data recovery technology to rescue and recover the lost electronic data in hard disk, server hard disk and floppy disk, mobile hard disk, USB or storable optical storage device. Fourth is interception. Electromagnetic leakage may also occur during the use of computer systems, and these leaked electromagnetic signals may contain some important information, so the relevant electronic data may also be intercepted by certain technical means.

In terms of collection of electronic chat records, the core content when collecting electronic chat evidence is the chat record itself, which can be provided by the network service provider; if the network service provider does not save it, it can be retrieved from the computer system used by the participant, by printing or copying to make it fixed.
