Research on cryptographic medical image information hiding method based on chaotic system
Zilong Liu · 2024
With the continuous advancement of internet technology, the transmission and storage of medical images in the network environment are becoming increasingly frequent. Ensuring the security of these image data has become an urgent and critical task in the field of medical information management today. This paper proposed a medical image encryption method with "numerical invariance" using the Kent chaotic system. Additionally, the paper explores methods for embedding text information within encrypted medical images. Experimental results indicated that the encryption scheme proposed in this study could restore the original medical images and their sensitive information without any damage during the decryption process, and effectively embedded and extracted text information within the encrypted medical images.
