In this paper, the proposed method hides the secret message based on searching about the identical bits between the secret messages and image pixels values. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the internet. For hiding secret information in images, there exists a large variety of steganography techniques some are more complex than others and all of them have respective strong and weak points The first to employ hidden communications techniques -with radio transmissions- were the armies, because of the strategic importance of secure communication and the need to conceal the source as much as possible. Nowadays, new constraints in using strong encryption for messages are added by international laws, so if two peers want to use it, they can resort in hiding the communication into casual looking data. This problem has become more and more important just in these days, with which around thirty of the major - with respect to technology - countries in the world methods are discussed and analyzed based on the ratio between the number of the identical and the non identical bits between the pixel color values and the secret message values This property is used for proposed image encryption and for steganography to increase the security level of the encoded image and to make it less visible.Keywords

In this paper, intelligent (smart) surveillance systems, which are now watching the video and providing alerts and content based search capabilities, make the video monitoring and investigation process scalable and effective. The programmed that analyze the video and provide alerts are commonly referred to as video analytics. These are responsible for turning video cameras from a mere data gathering tool into smart surveillance systems for proactive security. Smart surveillance systems have been enabled by the advances in computer vision, video analysis, pattern recognition and multimedia indexing technologies over the past decade. Additional video cameras are necessary to complement the surveillance information, especially for large scale applications. We aim to investigate new techniques and design new intelligent algorithms, which have to make use of partial information from several video sources. One of those is robustness of these techniques to changes in the environment: illumination, size of the objects and many others. Sometimes, additional video cameras are necessary to complement the surveillance information, especially for large scale applications. We aim to investigate new techniques and design new intelligent algorithms, which have to make use of partial information from several video sources.

In watermark embedding database is embedded into image. Here first we store binary data of image in one data structure (suppose array) and database content in other array. Then copy content of image and database in third array. Watermarking algorithm which is used to recover a database from updated value. This is a web based watermarking technique, in which if software is stored in server then we can access it from client system. Digital watermarking can be used to embed various types of data, depending on the particular application and intended use. For example, a watermark in a digital movie file might simply identify the name or version of the movie. Alternatively, it might convey copyright or licensing information from the movie's creator. Or it might embed a customer or transaction number that could be used to identify individual payment or transaction data relating to that particular copy of the movie. But the number of bits that can be contained in a watermark itself today is typically modest enough to provide some basic codes or identifiers.Keywords

A study on the quantitative estimation of diversity in 32 selected grids in the bryophyte-rich localities of Assam, North East India has been carried out. Assessment was done in 160 macroplots of 10 m * 10 m, randomly established in the forest and within each macroplot, five microquadrats (10 cm * 10 cm) were placed at different habitats, viz. saxicolous, terricolous and epiphytic. A total of 80 taxa belonging to 29 species of liverworts under 18 genera and 10 families, and about 51 species of mosses belonging to 27 genera and 13 families were assessed. In the study area, Lejeuneaceae and Fissidentaceae as well as Cololejeunea latilobula (Herzog.) Tixier and Entodontopsis tavoyensis (Hook ex Harv.) W. R. Buck & R. R. Ireland were the dominant families and taxa respectively. Four species were new additions to NE India, and seven taxa were reported for the Assam region. The present study elucidates the bryophyte species diversity and the species richness, and evenness of the region, which can further define their importance in the community.Keywords

Routing of data packets is a critical process on the internet, and routing protocols play a vital role in enabling routers to connect to internetworks using Internet protocols. Internet applications use various routing protocols, such as RIPng, OSPFv3, EIGRPv6, etc., each with its own approach to routing packets. This study presents a basic comparative analysis of as RIPng, OSPFv3, EIGRPv6 protocols. RIPng is an IPv6 routing protocol that allows routers to exchange routing information and calculate the shortest path to a destination based on the number of hops required. OSPFv3 is an IPv6 routing protocol that allows routers to exchange routing information and calculate the shortest path to a destination based on the state of the network links and EIGRPv6 is an IPv6 routing protocol that allows routers to exchange routing information and calculate the shortest path to a destination using both distance-vector and link-state algorithms. The paper "A Comparative Study on Routing Protocols: RIPng, OSPFv3 and EIGRPv6 and Their Analysis Using GNS-3" presents a comparative study on the performance of RIPng, OSPFv3, and EIGRPv6, which are the IPv6 routing protocols equivalent to RIP, OSPF, and EIGRP in IPv4 networks.Keywords
