Robust Medical Image Authentication using 2-D Stationary Wavelet Transform and Edge Detection

Secure Watermarking Schemes and Their Approaches in the IoT Technology: An Overview

“…The exploration and development of the Edge Detection Technique (EDT) represent an integral part of algorithms, which are based on object detection as the EDT introduces the object outline [42]. The EDT hides data, which represents an efficient approach that should be taken into account since it assures perceptual transparency when the embedding capacity is found sufficiently huge [43].…”

“…In this classification, watermarking techniques are categorized into invisible and visible watermark techniques [60]. In invisible watermarking techniques, information is hidden inside the object [42]. The hidden process can be performed based on three techniques, which are: robust, fragile and semi-fragile techniques [61].…”

“…The DWT and DCT techniques are two of the most commonly used techniques for watermark conversions. In practice, higher object imperceptibility is provided by these two techniques, which in turn demonstrate a robust action against watermark attacks and object manipulation [42].…”

“…The reason behind this effectiveness refers to the invisible watermarking property, which is accompanied by the content. The significance of this application is based on tracing copies, which are illegally published [42,75].…”

“…In this application, the watermarking method is created based on the negotiation on several needs such as the capacity, robustness, privacy and imperceptibility [42]. A patient can obtain some benefits and the right for a cure according to some significant tasks, which are derived by particular reports.…”
