Query: StegHash: New Method for Information Hiding in Open Social Networks   In this paper a new method for information hiding in open social networks is
introduced. The method, called StegHash, is based on the use of hashtags in
various open social networks to connect multimedia files (like images, movies,
songs) with embedded hidden messages. The evaluation of the system was
performed on two social media services (Twitter and Instagram) with a simple
environment as a proof of concept. The experiments proved that the initial idea
was correct, thus the proposed system could create a completely new area of
threats in social networks.
