- W4367011767 abstract "The COVID-19 scenario, there was a massive increase of medical imaging data. Designing an authentication technique for safeguarding medical photographs is a difficult task. This research intended to create a hybrid authentication system that combines image encryption with a durable watermarking mechanism. The invisibility of the watermark and its resistance to attacks are the two most important requirements for watermarking. The sensitivity of encryption algorithms in the presence of noise is also discussed in the paper. For watermark embedding, the paper presented edge detection (ED) of the discrete wavelet transform (DWT) coefficient. The first-level DWT coefficients are deconstructed from the enlarged medical image. To maintain invisibility, the edge coefficients are calculated over the high-frequency DWT sub-band. Objective of this paper is to safeguard the watermark image with quick and simple image encryption. For image encryption, a random key is created. The efficiency of encryption is also tested over noisy attack for the PSNR and NC." @default.
