Research on Voice Characteristic of Instant Messaging

随着全球信息化的飞速发展，互联网违法犯罪不断增长。电子数据取证技术作为一个新兴的研究领域，将计算机调查和分析技术应用于犯罪侦查，并收集适合呈现在法庭上的电子证据。本文结合电子数据取证鉴定实务的需求，在分析国内外现有的电子数据取证标准的基础上，结合最新发布的国际标准ISO／IEC27037，提出电子数据取证标准体系的整体框架，并分析了在数据加密、云计算和大数据背景下电子数据取证标准面临的挑战。

With the development of Internet and information technology, the digital crimes are also on the rise. Digital forensics is an emerging research area that applies computer investigation and analysis techniques to help detection of these crimes and gathering of digital evidence suitable for presentation in courts. Combining the needs of digital forensics practice,on the basis of analysis of the domestic and international standards, combining the latest release of ISO/ IEC 27037, this paper proposed standard system of digital forensics. In conclusion, the challenges under the back ground of data encryption,cloud computing and big data were analyzed.
