Abstract
The widespread use of digital technologies
increases the size of data stored in digital media. The increased amount of
stored data also brings along data security risks. One of the most important
risks in personal data security is the unauthorized or accidental data
deletion. There are file recovery and carving software for recovering deleted
files from the storage devices. Files must be loaded into RAM to be used in the
operating system. These files are stored in RAM for a certain amount of time by
the memory manager. Therefore, a file opened or deleted by the user in the
operating system can be found in the RAM. File carving techniques must be
applied to RAM to access these files.
In this study, the file carving and the performance
values of the multimedia files carved by using different signature structures
with file carving software from the RAM image were compared. In the study,
carving has been performed with the header and footer signatures of the used
and terminated multimedia files (JPG, PNG, GIF, BMP) used in Windows 10
operating system. In the carving process, file carving durations and carving
success rates are extracted using different signature structures of the same
file type. In the light of these results, the performance data of multimedia
file types are evaluated according to the signature structures used. The RAM
image retrieval and file carving software used in the study has been developed
by us as a part of the Ph.D. project.
