Identification and recovery of video fragments for forensics file carving

In digital forensics, file carving of video files is an important process in the recovery of video evidence needed for many criminal cases. Traditional carving techniques recover video files based on their file structure. However, these techniques fail in cases where the file is split into several fragments, especially if some of the fragments were overwritten. In this paper, we present a method for identification and recovery process of video fragments if the video Codec specifications were overwritten. It consists of two parts which are detector and validators. The detector looks for sequences of bytes that could be video fragments in forensics image. The validator decides to accept or reject that a given fragment is a part of a video file. Based on the proposed method we implement a prototype which is called VidCarve. We have conducted several experiments to evaluate the proposed method with current video carving tools. Experimental results show that the discussed method can identify video fragments with high rates of precision and recall. The overall performance rate can produce forensically sound evidence and play a vital role in the process of recovery of digital evidence in many criminal cases

Cybersieves

This Article offers a process-based method to assess Internet censorship that is compatible with different value sets about what content should be blocked. Whereas China\u27s Internet censorship receives considerable attention, censorship in the United States and other democratic countries is largely ignored. The Internet is increasingly fragmented by nations\u27 different value judgments about what content is unacceptable. Countries differ not in their intent to censor material-from political dissent in Iran to copyrighted songs in America-but in the content they target, how precisely they block it, and how involved their citizens are in these choices. Previous scholars have analyzed Internet censorship from values-based perspectives, sporadically addressing key principles such as openness, transparency, narrowness, and accountability. This Article is the first to unite these principles into a coherent methodology. Drawing upon scholarship in deliberative democracy, health policy, labor standards, and cyberlaw, this Article applies this new framework to contentious debates about sales of censorship technology by Western companies, public law regulation of these transactions, and third-party analysis of Internet censorship

The Dual-System Problem in Complex Conflicts

Conflict and fragile environments are increasingly complex and unpredictable, but the U.S. policy system itself is much more complex and unpredictable than most leaders appreciate. In this monograph, the authors argue that until we get a grasp on this “dual-system problem,” the United States will fall further and further behind in its strategic ambitions.https://press.armywarcollege.edu/monographs/1393/thumbnail.jp
