Invisible Video Watermarking for Data Integrity and Security based on Discrete Wavelet Transform – A Review

Abstract

To maintain the data integrity of transmitted video is very essential to secure any web-based system. Implementation of the invisible video watermarking is the best solution by using discrete wavelet transform gives us secured transformation in image processing applications. This method is also implemented as a 2-factor authentication (2FA) to secure the system. To protect the piracy of important data we implemented the above method.

The major issue of illegal manipulation and sending/receiving of digital video becomes a big problem. To resolve this kind of issue, a latest and new technology has been suggested or we can say that proposed. Basically, it is a mechanism of implant copyrights information into a bit streams of any kind of video, the video may be any type i.e. it will be study purposed, presentation purposed, organization purposed and entertainment purposed. In this kind of scheme, the random segmentation and reconstruction of implants secrete data is done without having or knowing the original provider video. Throughout this process, confidential data or sensitive data is implanted in separate video frames using the DWT’s frequency territory. DWT means Discrete Wavelet Transform. In the DWT’s i.e. discrete wavelet transforms video watermark mechanism has been inaugurated for securing the confidential or sensitive data. We proposed a Haar wavelet ground (based) digital watermark mechanism to secure confidential or sensitive data.
