Quantum Video Information Hiding Based on Improved LSQb and Motion Vector

Abstract

Quantum information hiding will have important researching value in quantum computer era. It is more appropriate for videos to be carriers for information hiding than images because of its bigger information content. A novel quantum video information hiding algorithm is proposed based on improved LSQb and motion vector of quantum video. Based on quantum color video representation QVNEQR, the improved LSQb information hiding algorithm is implemented on the original quantum video domain. Then, the improved LSQb is selected to embed the secret information into the motion vector to make the steganography more secure. Experimental simulations conducted on a simple video demonstrate the efficiency of the proposed approach.
