“…Hence, the main advantage of this arrangement is eliminating the highly noise-affected bits from the string. This method is proven successful against JPEG-2000 in single quality layer scenario [19], which grabbed our interest in choosing this algorithm for compression. The proposed algorithm is intended to reduce the effect of noise in the compressed domain using DWT.…”

“…We have taken these issues into consideration in our proposed work. A discrete wavelet transform (DWT)-based encoding mechanism is used to embed the watermark [17,18] and the noise-resilient compression technique of the independent pass coding (INPAC) algorithm [19] is used for compressing the data.…”

This paper introduces a robust and noise-resilient compressed domain video watermarking technique for data authentication and copyright protection. In recent years, watermarking has emerged as an essential technique to be equipped with data transmission. The main challenge pertaining to transmission is to protect the watermark from noise introduced by the channel. Here, we address this issue by watermark replication and by using the independent pass coding (INPAC) algorithm for compression. A replicated watermark is embedded into the video by the proposed blind video watermarking algorithm and then the watermarked video is compressed by the INPAC algorithm. The compressed video is transmitted through binary symmetric channels and tested under various bit error rates to evaluate the proposed algorithm in noisy environments. The results obtained suggest that the proposed algorithm is capable of handling noise efficiently and the overhead due to key embedding is observed to be only about 3%.
