Abstract:

High-definition videos lose hidden information when compressed by lossy channels during transmission. Concurrently, efficient video steganography algorithms require hardware implementation to achieve low-power, high-speed, and reliable real-time processing. To ensure real-time and reliable transmission of secret data, the steganography algorithm requires low complexity and high robustness. Therefore, this study proposes an efficient and robust steganography algorithm for hardware platform implementations. The algorithm employs the generation principle and distribution characteristics of DC (Direct Current) coefficients to modify the pixel values directly in the spatial domain rather than in the discrete cosine transform domain. Therefore, the proposed algorithm exhibits both the simplicity of the spatial-domain steganography algorithm and the high robustness of the transform-domain steganography algorithm. Experimental results show that the proposed algorithm has low computational complexity and exhibits excellent robustness and visual quality in local lossy channel compression.
