Due to the advanced network technology, security of data transformation is a big problem in this society. The usage of cryptography secret key method along with watermarking provides the security of data transmission. Cryptography is a tool that can be used to keep information confidential and to ensure its integrity and authenticity. Cryptography is a method of encryption and decryption. The encryption is used to securely transmit the data in open network. Each type of data has its own features; therefore different technique should be used to protect confidential data from an unauthorized access. The proposed technique is simple to implement and has high encryption rate of security and this method embed the data into the image. The image is encrypted using secret key method and then watermarked into video signal. This encrypted image is transmitted through video signal and the security analysis is measured using some parameters. The comparison between the different file formats of the video signal.
