近几十年来，我们见证了信息技术的发展，从超大规模集成电路技术的发展，到通信和网络基础设施，再到多媒体压缩和编码方案的标准化，再到有效的多媒体内容搜索和检索。因此，多媒体设备和数字内容变得无处不在。这条技术发展的道路自然导致了下一步必须解决的关键问题，即确保内容、设备和知识产权被授权用户用于合法目的，并在其他情况下能够高度自信地进行取证证明。当安全受到损害、知识产权受到侵犯或真实性被伪造时，法医方法和工具被用来重建数字内容发生了什么，以便回答谁做了什么，何时，在哪里，以及如何做。本文的目的是概述过去十年来在新的和新兴的信息取证领域在理论、方法、最新技术和主要应用方面所做的工作，并对未来进行展望。
In recent decades, we have witnessed the evolution of information technologies from the development of VLSI technologies, to communication and networking infrastructure, to the standardization of multimedia compression and coding schemes, to effective multimedia content search and retrieval. As a result, multimedia devices and digital content have become ubiquitous. This path of technological evolution has naturally led to a critical issue that must be addressed next, namely, to ensure that content, devices, and intellectual property are being used by authorized users for legitimate purposes, and to be able to forensically prove with high confidence when otherwise. When security is compromised, intellectual rights are violated, or authenticity is forged, forensic methodologies and tools are employed to reconstruct what has happened to digital content in order to answer who has done what, when, where, and how. The goal of this paper is to provide an overview on what has been done over the last decade in the new and emerging field of information forensics regarding theories, methodologies, state-of-the-art techniques, major applications, and to provide an outlook of the future.
