TLDR
Experimental results show that a hardware-based video authentication system using this watermarking technique features minimum video quality degradation and can withstand certain potential attacks, i.e., cover-up attacks, cropping, and segment removal on video sequences.Abstract:
This paper presents a hardware implementation of a digital watermarking system that can insert invisible, semifragile watermark information into compressed video streams in real time. The watermark embedding is processed in the discrete cosine transform domain. To achieve high performance, the proposed system architecture employs pipeline structure and uses parallelism. Hardware implementation using field programmable gate array has been done, and an experiment was carried out using a custom versatile breadboard for overall performance evaluation. Experimental results show that a hardware-based video authentication system using this watermarking technique features minimum video quality degradation and can withstand certain potential attacks, i.e., cover-up attacks, cropping, and segment removal on video sequences. Furthermore, the proposed hardware-based watermarking system features low power consumption, low cost implementation, high processing speed, and reliability.read more

Robust Image Hashing Based Efficient Authentication for Smart Industrial Environment
TL;DR: A novel feature extraction strategy is employed in the proposed image hashing approach for authentication by extracting two important features: the positions of rich and nonzero low edge blocks and the dominant discrete cosine transform coefficients of the corresponding rich edge blocks, keeping the computational cost at minimum.

Blind reliable invisible watermarking method in wavelet domain for face image watermark
TL;DR: It is observed that DWT based watermarking method coupled with weighted binary coding has the best performance without attacks; peak signal to noise ratio value of watermarked image is greater than 50 dB and normalized correlation coefficient value of extracted watermark is 1 at the watermark embedding strength of 1.

TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.

TL;DR: The proposed method is robust and of much lower complexity than a complete decoding process followed by watermarking in the pixel domain and re-encoding, and is also applicable to other hybrid transform coding schemes like MPEG-1, MPEG-4, H.263.
