Hiding Color Image within a video file using Discrete Wavelets Transform and Artificial Neural Networks

Abstract

Growing up technology services and the needing to exchange various information lead to accumulating a large amount of data across computer networks. Internet and private networks are examples of such networks. Transferring the data between computers increases the risk of un-authorizing access of unauthorized people. Protecting data is so important to be safe from unexpected and invisible threats, which are difficult to detect as most notably intrusion and infiltration.The aim of this paper is to hide a digital color image inside a digital video file using the Discrete Wavelets Transform (DWT) and Artificial Neural Networks (ANNs). The digital video file, which represents the cover, is splitted into a set of frames and partitioned into three colored layers (red, green and blue). The discrete wavelets transform technique is applied to each one of the three layers.To hide the colored image (watermark), it is firstly partitioned into the three colored layers (red, green and blue). Then, it is layered into a set of clusters. The ANNs are used as artificial hiding techniques to hide each cluster in the digital video file.The results showed that the use of the DWT and ANNs are effective and encourage in hiding data. After applying this work algorithms to a set of samples, the results also showed harmony and compatibility in the process of concealment with the treated samples.
