RG_LSB

Implementation and Performance Analysis of LSB Steganography Algorithm. The test shows that it has excellent imperceptibility (PSNR value all above 50), and the visual observation of the embedded graph is no different from the original graph. In the case of no attack, the error rate of watermark extraction is 0%, indicating an excellent extraction effect.

RG_SM3hmac

Fast Realization of HMAC based on SM3 Algorithm. Written in pure C and run in Linux environment, the HMAC calculation is basically maintained at the level of milliseconds, and the calculation rate is maintained at around 72MBps. The calculation delay can be ignored for processing messages below 10MB, and the calculation rate is the best for hundred KB level messages.

RG_DCT

Implementation and Performance Analysis of DCT Steganography Algorithm. Tests found that it has excellent imperceptibility (PSNR all above 40). When encountering noised images, the error rate of watermark extraction is low, indicating certain robustness. By introducing the scaling factor, the best embedding effect can be obtained for the specific carrier and watermark.
