A light weight and secure video conferencing scheme utilizing public network



Security of video encryption schemes is an issue yet to be addressed to the satisfaction of all parties concerned. In the one end of the spectrum, there are applications which require highest level of security and they use conventional encryption schemes which are neither bandwidth efficient nor format preserving. Thus limit their application to a large extent. Other end of the spectrum is occupied by selective encryption schemes which are used by most of the commercial applications. These schemes though bandwidth efficient are not secure as these schemes are designed to degrade the video quality but overall content remain intelligible. Thus a scheme which is highly secure yet bandwidth efficient is the need of the hour. In this paper, we propose a new format preserving selective encryption scheme for JPEG and MPEG which is compression friendly as well as highly secure. We choose the quantized DCT coefficients of the I-frame for encryption. The resultant image/video is completely obscure and is suitable for high end security applications. Also there is no reduction in the performance of compression algorithms applied later in the standard JPEG/MPEG pipeline. Experiments show that the encrypted image/video file is almost of the same size as that of un-encrypted version. Thus the scheme is suitable for applications like tele-medicine, on-the-go video conferencing using low bandwidth cellular networks, etc..
