Image data privacy protection technology based on reversible information hiding and robust secret sharing

In the digital age, image data security and privacy issues are critical challenges for society, commerce, and technology. By dividing images into multiple copies and distributing them among participants, highly secure sharing of secret information is achieved. Reversible information hiding technology is then used to embed secret information, enhancing privacy protection. Experimental analysis confirms the robustness and performance of this method under different noise and tampering conditions. Results demonstrate the method's effectiveness, maintaining an average peak signal-to-noise ratio of 31.26 dB even under heavy tampering. Despite a noise intensity of 0.005 and a 50 % tampering area, the peak signal-to-noise ratio remains at 46.57 and 31.78, respectively, preserving image quality. Compared to existing schemes, the method improves embedding rates by 2.99bpp and 3.0bpp. This study expands the field and finds practical applications in safeguarding different types of data with optimized algorithm performance.
