Biometric Security Through Visual Encryption for Fog Edge Computing

Fog and mobile edge computing have gained considerable attention from the research and development community. The problems related to security and privacy of biometric content are simpler to solve through edge computing resulting in improved security and privacy of biometric and other critically private information. Zero-watermarking has been proposed as a solution to help protect the ownership of multimedia content that is easy to copy and distribute. Visual cryptography is another approach to secure data that is to be shared through generating multiple shares. This paper is concerned with developing a biometric security solution for face images, using visual cryptography and zero-watermarking, that does not adversely impact the visual quality of the image. The original face image is not modified through the zero-watermarking and visual encryption procedures and this in turn does not adversely impact the recognition rate

A Novel Approch for Digital Image Watermarking Using Cryptography

Medicinal images can be made more secure by using enhanced watermarking technique; it allows us to embed the related information with the image, which provides secrecy, integrity and validation by embedding encrypted digital signature with the image. The diverse characteristics of watermarking algorithms are discussed in this paper. The performance evaluation of embedding the watermark in DWT domains is analyzed taking PSNR and MSE as the evaluation parameters. In this paper, data hiding and cryptographic techniques are combined into one secure simple algorithm. So, the original image is not mandatory at the time of watermark recovery. Because we insert final watermark in DWT domain, so this procedure is robust against many attacks

A Study on Invisible Digital Image and Video Watermarking Techniques

Digital watermarking was introduced as a result of rapid advancement of networked multimedia systems. It had been developed to enforce copyright technologies for cover of copyright possession. This technology is first used for still images however recently they need been developed for different multimedia objects like audio, video etc. Watermarking, that belong to the information hiding field, has seen plenty of research interest. There's a lot of work begin conducted in numerous branches in this field. The image watermarking techniques might divide on the idea of domain like spatial domain or transform domain or on the basis of wavelets. The copyright protection, capacity, security, strength etc are a number of the necessary factors that are taken in account whereas the watermarking system is intended. This paper aims to produce a detailed survey of all watermarking techniques specially focuses on image watermarking types and its applications in today’s world
