Digital preservation is the active management of digital information over time to ensure ongoing access to the data. It is the management and maintenance of digital objects (the files, or groups of files, that contain information in digital form) so they can be accessed and used in future. It is error-free storage of digital information, with means for retrieval and interpretation, for the comp...

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 ...

This paper introduces the write-once/read-many XMLtape/ARC storage approach for Digital Objects and their constituent datastreams. The approach combines two interconnected file-based storage mechanisms that are made accessible in a protocol-based manner. First, XMLbased representations of multiple Digital Objects are concatenated into a single file named an XMLtape. An XMLtape is a valid XML fi...

Computer Forensics is a process of using scientific knowledge to collect, analyze and present digital evidence to court or tribunals. Since files are the standard persistent form of data on computers, the collection, analysis and presentation of computer files as digital evidence is of utmost essential in Computer Forensics. However, data can be hidden behind files and can be enough to trick th...

The paper describes the problem of using digital filters on the DICOM graphic files. An attempt has been made to improve the process of extracting information from graphic files generated by medical measuring instruments.

What if someone stopped you from accessing your files or even using your computer? What if they demanded an amount to get the access back to you? With most financial and social interactions revolving around three critical aspects – firstly the use of digital data and files, secondly computer systems and last the unsecure internet. This is where Ransomware using Bitcoin has become a major cause ...

The Arts and Humanities Data Service (AHDS) was established in 1996 to collect, preserve and encouraging the reuse of digital resources created during scholarly research in the arts and humanities. The AHDS is now responsible for the preservation of over 3,000 digital resources and holds a wide range of data types, from plain text and image files to datasets (spreadsheets, databases, statistica...

This paper seeks to advance digital preservation theory and practice by presenting an evidence-based model for identifying barriers to digital content rendering within a bit-level preservation repository. It details the results of an experiment at the University of Illinois at Urbana-Champaign library, where the authors procured a random sample of files from their institution’s digital preserva...
