Watermarking Analysis of Digital Image Using Various Approaches: A Review
Abstract: AbstractFor present security to the digital media on the net the very beneficial generation is, virtual watermarking (DW). Watermark is an image or pattern in document which is used to identify data authentication and data integrity. The user can check the watermarked records with the watermark key and watermarking extraction system. The different techniques of watermarking reviewed in this paper are: least significant bit (LSB), robust, discrete cosine transform (DCT), …

Analysis of Invisible Image Watermarking Based on Spatial and Frequency Domain Techniques (LSB, Patchwork, DCT, DWT, DFT)
Abstract: AbstractWith rapid development, seed technology, secure transmission of information is very intricate. For harmless and protected transmission of information, digital watermarking can be utilized. Watermarking of advanced images is a system of concealing information; likewise, it gives security of information or distinguishing data in the computerized information. The computerized watermarking process implants a sign into the media without altogether debasing its visual quality. We additionally talk about a portion of …

Robust Color Image Watermarking using Biometric Protection and Image Authentication Key
Abstract: In recent days, it becomes difficult to provide protection to color images which were captured by modern capturing devices. This paper presents a novel work on copyright protection by providing authentication process for extraction of watermark of color still images. New blind frequency domain non-correlation based watermarking algorithm using one dimensional Walsh coding technique is introduced to improve the robustness. The developed algorithms do not required the original image for …

Providing Biometric Protection for Iris using Watermark and Visual Cryptography
Abstract: This paper presents a novel security architecture which protects the iris using watermarking and visual cryptography techniques. The iris region is protected using watermarking technique where we are using DCT to embed the watermarked text image into the iris image in the low frequency band. After performing watermarking, the watermarked image is further processed to generate a template using Daugmans method and Gabor filter. The generated template is then gone …
