The present workproposes to perform an analysis of the similarities between the least significant two bits of the cover image and multiple series of two-bit-length encrypted frames, all of them from the crypto-message. After finding the most similar frame, we proceed to substitute it into the cover image; nevertheless, to provide a proof of the improvement from using itor the least similar one, the statistics from both cases are obtained.Providing information that the more similar the frame is, the better statistics the stego-image has. Moreover, the statistics obtained from our work are also compared with other works, finding that we provide a good scheme for hiding information.

Abstract

After finding the most similar frame, we proceed to substitute it into the cover image; nevertheless, to provide a proof of the improvement from using itor the least similar one, the statistics from both cases are obtained.Providing information that the more similar the frame is, the better statistics the stego-image has. Moreover, the statistics obtained from our work are also compared with other works, finding that we provide a good scheme for hiding information.
