Abstract

Sensitive data is exchanged frequently through wired or wireless communication that are vulnerable to unauthorized interception. Cryptography is a solution to overcome this issue, but once decrypted the information secrecy does not exist. Apart from hiding data in an image, it can be extended for digital media. In this work, data hiding and extraction is proposed for Audio Video Interleave videos, that embeds the image in Bitmap Image File, that has the secret information in a frame of the video by segmenting the bytes of the secret image and placing them in the video frame providing a higher level of encryption. This novel method provides a two level encryption, thus to decipher the data, the way in which the secret image is originally decomposed and the frame in which it is embedded should be known. The quality of the secret image embedded and the size of the video is not altered before and after encryption of the secret data. The secret image may contain any multimedia data that can be further extracted and recognized.
