In recent times, the application of deoxyribonucleic acid (DNA) has diversified with the emergence of fields such as DNA computing and DNA data embedding. DNA data embedding, also known as DNA watermarking or DNA steganography, aims to develop robust algorithms for encoding non-genetic information in DNA. Inherently DNA is a digital medium whereby the(More)

—Slepian's variant I permutation coding has been recently shown to be a fundamental steganographic tool, as it implements optimum perfect steganography of memoryless sources. Although real host signals are not memoryless, a decorrelating energy-preserving transform can always be applied before a method that assumes a memoryless source, as is usually done in(More)
—A theoretical analysis and a practical solution to the fundamental problem of optimum perfect universal steganog-raphy of finite memoryless sources with a passive warden are provided. The theoretical analysis rests on the fact that Slepian's Variant I permutation coding implements first-order perfect universal steganography with maximum embedding rate. The(More)
