Adaptive steganography algorithm based on binary image

Abstract

The invention discloses an adaptive steganography algorithm based on a binary image. The adaptive steganography algorithm based on the binary image comprises the following steps: calculating perturbation of a carrier image according to image texture features, dividing the carrier image into blocks, scrambling image blocks, encrypting secret information, performing STC encoding embedding, reverselyscrambling the encrypted image blocks, and restoring the encrypted image to obtain the encrypted image having the complete texture and the embedded secret information. According to the invention, a novel carrier scrambling algorithm having high security performance and capable of effectively resisting exhaustion cracking is used; through combination of a high-detection resistance measurement method and STC encoding, a designed binary image information hiding method has very high security performance and detection resistance and plays a very important role in secure covert communication.

Description

technical field [0001] The invention belongs to image information hiding in the field of information hiding, and in particular relates to an adaptive information steganography algorithm based on a binary image. Background technique [0002] Traditional secret communication adopts the method of encrypting the message, without the key, the third party cannot read the effective secret information. However, the fact of secret communication is easily exposed. Tracking, destruction or modification of secret information will destroy the communication behavior and cause communication failure. Information hiding technology is relatively more concealed. It hides the encrypted information in the carrier. The difference between the carrier after hiding the secret information and the original carrier is very small, and it cannot be found within the normal range of human senses. The existence of secret communication. Information hiding has been a technology to achieve secure communicati...
