SocialStegDisc: Application of steganography in social networks to create a file system

摘要

In this paper, the concept named SocialStegDisc was introduced. This concept is as an application of the original idea of StegHash method which uses multimedia files as a carrier of hidden information and connects them logically with a mechanism of hashtags. SocialStegDisc is a new kind of mass-storage characterized by unlimited space and provides the set of operations on files: creation, reading, deletion and modification. Furthermore, the attempts to improve the operation of StegHash by trade-off between memory requirements and computation time are presented: a) an application of linked list structure; b) introduction of a dynamic verification of free addresses to the multimedia objects. The features, limitations and opportunities of the design were discussed.
