Reconstructing corrupt DEFLATEd files
We present a method by which to determine a synchronzation point within a DEFLATEcompressed bit stream (as used in Zip and gzip archives) for which the beginning is unknown or damaged. Decompressing from the synchronization point forward yields a mixed stream of literal bytes and co-indexed unknown bytes. Language modeling in the form of byte trigrams and word unigrams is then applied to the re...
متن کاملImproved recovery and reconstruction of DEFLATEd files
This paper presents a method for recovering data from files compressed with the DEFLATE algorithm where short segments in the middle of the file have been corrupted, yielding a mix of literal bytes, bytes aligned with literals across the corrupted segment, and coindexed unknown bytes. An improved reconstruction algorithm based on long byte ngrams increases the proportion of reconstructed bytes ...
متن کاملConfessions that corrupt: evidence from the DNA exoneration case files.
Basic psychology research suggests the possibility that confessions-a potent form of incrimination-may taint other evidence, thereby creating an appearance of corroboration. To determine if this laboratory-based phenomenon is supported in the high-stakes world of actual cases, we conducted an archival analysis of DNA exoneration cases from the Innocence Project case files. Results were consiste...
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 کاملReconstructing fragmented gel files created by Model 377 DNA Sequencers.
To our knowledge, the most widely used automated DNA sequencers are manufactured by PE Applied Biosystems (Foster City, CA, USA). Our laboratory uses Model 377 Sequencers equipped with the XL upgrade (i.e., collection software Version 2.0 and analysis software Version 3.0). Power transients, network noise, an excessively fragmented hard disk or other such incidents can cause a sequencer to prem...
