Abstract:

The project proposes the enhancement of security system for secret data communication through video file using adaptive data hiding with cryptographic technique. A given input video file is converted into frame sequences and one of frame will be selected to conceal the secret data for secured data communication. The proposed technique uses public key cryptography for encrypting a secret text data into cipher text to avoid data hacking issues. After data encryption, the data hider will conceal the secret encrypted data into the selected frame using adaptive embedding algorithm. Although encryption achieves certain security effects, they make the secret messages unreadable and unnatural or meaningless. These unnatural messages usually attract some unintended observers’ attention. The data hiding technique uses the LSB replacement algorithm for concealing the secret message bits into the image in frequency domain. An Integer wavelet transform is used to determine the high frequency components for effective data concealing for preserving image quality. In the data extraction module, the secret data will be extracted by using relevant key for choosing the pixel coefficient sand it will be decrypted to get original data using private key. Finally the performance of this proposal in data encryption and hiding will be analyzed based on image and data recovery.
