Digital watermarking is a technique for hiding identification data for copyright authentication. The study adapts digital watermarking to interleave patient information with medical images, aiming to reduce storage and transmission overheads. The approach encrypts patient text, compresses graphical signals, and interleaves them with the image using DPCM and ADPCM compression techniques. The technique’s compression and encryption performance were demonstrated in a specific example, with results tabulated.
Digital watermarking is a technique of hiding specific identification data for copyright authentication. This technique is adapted here for interleaving patient information with medical images to reduce storage and transmission overheads. The text data are encrypted before interleaving with images to ensure greater security. The graphical signals are compressed and subsequently interleaved with the image. Differential pulse-code-modulation and adaptive-delta-modulation techniques are employed for data compression, and encryption and results are tabulated for a specific example.
