Byte embeddings for file fragment classification
Future Generation Computer Systems, 2022Abstract In digital forensics, file carving is the process of recovering files on a storage media in part or in whole without any file system information. An important problem in file carving is the identification of fragment types. Many fragment classification studies in the literature employ inflexible and indiscernible feature selection methods ...

Carving Orphaned JPEG File Fragments
IEEE Transactions on Information Forensics and Security, 2015File carving techniques allow for recovery of files from storage devices in the absence of any file system metadata. When data are encoded and compressed, the current paradigm of carving requires the knowledge of the compression and encoding settings to succeed.

Resurrection: A Carver for Fragmented Files
2014The recovery of deleted files is an important task frequently carried out by professionals in digital forensics and data recovery. When carried out without information from the file system, this process is called file carving. The techniques implemented in today’s file carvers are mostly sufficient for non-fragmented files.

Neural Networks for File Fragment Classification
2019 42nd International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO), 2019Abstract - File fragment classification is an important step in file forensics in which filetypes are assumed based on their available content fragments. Methods typically used for this task utilize machine learning techniques on features like byte frequency distributions and fragment entropy measures.

Identification of image fragments for file carving
World Congress on Internet Security (WorldCIS-2013), 2013Recovering images intact is an important process in digital forensics, as they may represent primary evidences in crime cases such as child pornography. Due to file syetems' fragmentation mechanisms, images may be split into several fragments on a physical storage.

Belief Fragments and Mental Files
2021Belief fragments and mental files are based on the same idea: that information in people’s minds is compartmentalized rather than lumped all together. Philosophers mostly use the two notions differently, though the exact relationship between fragments and files has yet to be examined in detail. This chapter has three main goals.

Fragmentation in Data Deduplication Systems II: The Jump Metric
International Symposium on Information TheoryData deduplication refers to a collection of data processing strategies that aim to remove repeated data chunks stored by different users. Despite providing excellent storage savings, deduplication can lead to severe file fragmentation issues: data ...
