Abstract

Aiming at the problem that the embedded capacity and security of the single-carrier information hiding algorithm can not be further improved because of the number of carriers, the carrier pre-processing and the embedding of secret information are combined with the image angle structure descriptor, and a multi-carrier information hiding algorithm based on the angle structure descriptor (ASD) is proposed. Firstly, the angle structure descriptors of the extracted image are used to classify the carrier set, and the image angle structure descriptor direction field coding is obtained. Secondly, the secret information is segmented according to the carrier classification number and the preprocessing such as scrambling and optimization is performed. Finally, based on the angle structure the coded data of the feature direction field performs information hiding on a plurality of types of carriers according to the information hiding rule. In particular, the “judgment selection” option is designed during secret information extraction to further improve the performance of the algorithm. The experimental analysis shows that the algorithm has good concealment, strong anti-analysis ability and robustness, and is suitable for applications such as large-capacity secret information covert communication with high security requirements.

Summary

INTRODUCTION

With the rapid development of the Internet and multimedia technology, the transmission and sharing of multimedia information have become increasingly simple and convenient, which is convenient for people’s lives and cause a lot of information security hidden danger. The above information hiding algorithm based on single-carrier can complete the transmission of secret information, the algorithm cannot further improve the embedding capacity and security due to the limitation of the number of carriers. The carrier classification and the secret information are embedded by the image angle structure descriptor, and fully considering the influence of inter-pixel embedding, and a multi-carrier information hiding algorithm based on image angle structural feature is proposed. When the secret information is extracted, because the ASD feature vector includes the magnitude relationship of the image HSV color space quantization value, the consideration of the case where the color quantization difference value is 1 increases the difficulty of information hiding analysis. This paper defines the angle structure in 2 × 2 image blocks based on three directions and provides an operational space for the information hiding carrier preprocessing while significantly describing the image features. We optimize the secret information hiding by the scrambling and optimization algorithm to complete the information hiding
