Webside effect that yields longer cryptographic signatures and watermarks is produced. Such an obstacle discourages [1] from being a robust watermarking method in resisting geo-metric attacks [6, 10]. On the other hand, it can also be observed that the ex-isting methods that were proposed to deal with the proto- WebJul 8, 2024 · Cryptography can also show that you are the legitimate owner of the data. Here we come into the area of secure time stamping, digital ledger and blockchain systems, a topic that will fill yet another conversation. Also, digital watermarking can be considered, but the ‘graveyard of broken watermark schemes’ has quite a large body count.

WebDigital images are transferred with ease through the network. Many users are using the images without the knowledge of the owners. Therefore, a novel watermarking scheme is proposed to ensure copyright protection and authentication of images using cryptography techniques. Here, a quick response (QR) image is generated for a watermark image that …
WebDigital image authentication is an extremely significant concern for the digital revolution, as it is easy to tamper with any image. In the last few decades, it has been an urgent concern for researchers to ensure the authenticity of digital images. Based on the desired applications, several suitable watermarking techniques have been developed to mitigate …

Lattice-based cryptography is one of the leading candidates for post-quantum cryptography. A major focus of my work has been on constructing new cryptographic primitives such as zero-knowledge proof systems, watermarking, and more, from standard lattice assumptions. campwareWebwatermark in this case is called blind watermark extraction. The inability to access the original signal limits the amount of data that can be embedded in a given host signal. It also renders data extraction more difficult.
