  ABSTRACT: The popularity of the Internet today and its complex junction of wires, connections, delivery mechanisms and addresses could not have possibly reached the outer limits of the imaginations of the Internet’s forefathers. Nor could they have imagined the associated commercial and social phenomena they were unleashing. The Internet has essentially changed the way that both individuals and businesses operate and communicate, especially in the developed world. This enormous growth in Internet use has not only led to increased demand for better, faster technology, but has also increased the demand for addresses from which to send and receive information. IP enables data to be sent from one computer to another in a network and is known as a connectionless protocol because there is no continuous connection between the two communicating devices. Internet Protocol version 6 or IPv6 is an improved version of the current and most widely used Internet Protocol IPv4. In this paper we discuss some of the security issues related to IPV6 and also compare the performance of IPV4 and IPV6. Versions.

  ABSTRACT: Steganography which is the idea of embedding secret data in different media has emerged as an important regulation of methods for data integration. Although it generally applied to still images in the past, is very popular in recent years for the video. The techniques of video data hide recent attention on features generated by video compression standard, a safer method for steganography uses MPEG-4 Bit Plane Complexity Segmentation (BPCS) algorithm is proposed in this framework. The reason for choosing such cover video in this approach is the enormous amount of data that can be hidden in every frame of MPEG-4 video standards. In other words, MPEG-4 has three types of pictures: I-frame, P-frames and B- frame that can give more flexibility to hide data at the higher security level. Unlike other techniques used for hiding data such as LSB algorithm, BPCS can achieve better results in both mathematics expression and Vision Human System since they are used as quality factors measurements. In this scheme, information security is built into the home videos of I-frame until the BPCS can reach high levels of integration with low distortion based on the theory that regions of low noise-levels as in a picture can be replaced by noise without a significant loss of image quality. This approach invents data hidden in high-security environments. Experimental results show the success of hidden data in the selected and data extracted from the sequence of frames and also indicate the effectiveness of the implementation plan of steganography compressed video with high security features.
