Keyless, Robust and Cost-Effective Privacy Protection Algorithm for Videos Using Steganography

In this paper, a novel reversible keyless steganography algorithm for video piracy protection which uses randomized pixel for hiding authentic information is proposed. Randomization at two different levels is considered which is not in any of the existing algorithms. It increases the security with low cost. This proposed approach enhances the andomization of the specific pixels where authentication information will be stored in a frame and the location of such modified pixels is stored in an immediate next frame. Each pair is identified with an embedded random number. Modified least significant bit (mLSB) is used to insert the authentication information bits which is cost effective due to simplicity and can withstand statistical attacks. During extraction, frame with pixel locations is used. The extracted information will be compared. Different quality metrics values proved that it can withstand visual attacks, whereas StirMark test proved its high robustness. © 2020, Springer Nature Singapore Pte Ltd.
