Crypto watermarking
WebThe first lattice-based construction of secret-key watermarking due to Kim and Wu (CRYPTO 2024) only ensures mark-unremovability against an adversary who does not have access to the mark-extraction oracle. The construction of Quach et al. (TCC 2024) achieves the stronger notion of mark-unremovability even if the adversary can make extraction ... WebSep 1, 2016 · Basically, when it is applied to images, watermarking modifies or modulates the image pixels’ gray level values in an imperceptible way in order to encode or insert a message (i.e. the watermark). The message can be a set of security attributes [3] that will protect the image while it is accessed.

WebDigital watermarking is a concept intimately related to 1) Least Significant Bit Coding (LSB): steganography, in that they both hide a message inside a The LSB of the carrier signal is substituted with the digital signal. … WebWatermarking is a useful tool both for protecting ownership and for preventing unauthorized distribution of digital media. Software watermarking. In this work, we focus on software watermarking for cryptographic functionalities.
WebSep 1, 2016 · The jointly watermarking/decryption process is similar to the encryption. Using Ke, the set of indices t j is generated. The s entries of Dk are summed and the result is added to X e giving access to the watermarked vector Xw (7) X w = X e + ∑ j = 1 s D k [ t j] = X + ∑ j = 1 s W k [ t j] = X + M t k where M t k = ∑ j = 1 s W k [ t j]. WebAug 25, 2016 · In this paper, we describe a region-based, crypto-watermarking algorithm capable of providing confidentiality, authenticity, and integrity for medical images of …
WebWatermarking is a strategy that is broadly utilized and ceaselessly created by utilizing different strategies and executions [ 7, 8 ]. In the proposed method, discrete wavelet transform (DWT) and singular value decomposition (SVD) techniques are combined to accomplish the vigor and imperceptibility of the watermark.
WebApr 25, 2024 · In order to contribute to safe sharing, transfer and indexing of 3D multiresolution meshes, a new crypto-watermarking approach is proposed based on spherical harmonics and AES encryption algorithm. Data to be inserted, in this case, is a grayscale image already encrypted using AES256 algorithm.
