Optimal Path Construction for Fragmented File Carving
Fragmented File carving is an important technique in Digital Forensics to recover files from their fragments in the absence of the file system allocation information. In this paper, the fragmented file carving problem is formulated as a graph theoretic problem. Using this model, we describe two algorithms, “Optimal Carve” and “Probabilistic-based Carve”, to perform file reconstruction and recov...
متن کاملImplementation of Greedy Sequential Unique Path
Digital Forensic Analyst encounters a mixed file fragments in the absence of File Table information i.e., files‟ metadata. File Carving is a process of reconstructing files from mixed file fragments without using files‟ metadata. File Carving is an interesting and challenging problem in digital forensics and Data Recovery. Recently there have been number of research papers in the area of File C...
متن کاملAdvanced File Carving Approaches for Multimedia Files
File carving is a recovery technique that recovers files based on information about their structure and content without matching file system information. As files can be recovered from their content and/or file structure this technique is indispensable during digital forensics investigations. So far many approaches for the recovery of digital images have been proposed. The main contribution of ...
متن کاملClassification and Recovery of Fragmented Multimedia Files using the File Carving Approach
File carving is a recovery technique which does not consider file tables or other meta-data which is used to organize data on storage media. As files can be recovered based only on their content and/or structure, this technique is an indispensable task during digital investigations. The main contribution of this paper is the description of procedures that allow for successful content-based reco...
متن کاملCarving Contiguous and Fragmented Files with Object Validation
‘‘File carving’’ reconstructs files based on their content, rather than using metadata that points to the content. Carving is widely used for forensics and data recovery, but no file carvers can automatically reassemble fragmented files. We survey files from more than 300 hard drives acquired on the secondary market and show that the ability to reassemble fragmented files is an important requir...
