Cryptographic watermarking

WebCryptography and image watermarking are domains that provide multiple security services, such as authenticity, integrity, and privacy. In this paper, a digital image watermarking technique is proposed that employs the least significant bit (LSB) and canny edge detection method. The proposed method provides better security services and it is ... WebDec 30, 2024 · Cryptographic Watermark A watermark is a semi-transparent mark (a logo or text) that is embedded onto an image.

Webwatermark 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. In this paper, a cryptographic watermark embedding tech-nique based on discrete logarithm is proposed. The proposed WebA cryptographic watermarking technique for multimedia signals 269 potentially detectable. While in frequency domain approaches, the watermark signal is embedded into the spectrum of the host image generated through the Fourier transform. The embedded watermark is therefore distributed to the entire host image following the inverse Fourier ... 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].

A cryptographic watermarking scheme embeds a message into a program while preserving its functionality. Recently, a number of watermarking schemes have been proposed, which are proven secure in the sense that given one marked program, any attempt to remove the embedded message will substantially change its functionality.
