Abstract :
In widespread system the number of set of
connections technology enhance rapidly. Sometimes the illegal activity also gets increased. That means the not permitted persons can cut the information in which the hackers may be from inside and outside. The costly information is always attack by the invader in the network. Attacks may occur in many ways. These attacks are otherwise called as threat. Using multiple methodologies the attackers may combine many hacks. So an well-organized security system is desired in networking system to avoid hacking. Therefore, an proficient security model is necessary to save from harm undisclosed information over the network system. However, many security systems have been introduced for the protection purpose. Here we use two the latest thing security techniques, cryptography and steganography, which performs better in contrast of other existing regular and mechanical safety methods.
