Identification and Recovery of JPEG Files with Missing Fragments
Recovery of fragmented files proves to be a challenging task for encoded files like JPEG. In this paper, we consider techniques for addressing two issues related to fragmented JPEG file recovery. First issue concerns more efficient identification of the next fragment of a file undergoing recovery. Second issue concerns the recovery of file fragments which cannot be linked to an existing image h...
متن کاملImproved Redundancy Reduction for Jpeg Files
In this paper several methods are presented that allow improved compression of JPEG image files. This is mainly achieved through segmented entropy coding in reference to the EOBs (End-of-Block) of the 8x8 DCT transformed macroblocks. All of the algorithms discussed here are implemented in the freely available JPEG compression software 'packJPG' [9]. Our approach reduces baseline JPEG image file...
متن کاملReconstructing Fragmented YAFFS2 Files for Forensic Analysis
Data recovery from captured intelligent mobile devices such as smartphones plays a significant role in digital forensic analysis. In this paper, we study the main characteristics of NAND flash and YAFFS2 file systems and explore the method for recovering YAFFS2 files for forensic analysis based on Tnode tree that can save a lot of time compared to other data recovery methods. For any broken fil...
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...
