We present a novel technique for image steganography which belongs to techniques taking advantage of sharp areas in images in order to hide a large amount of data. In this paper a survey is done on various techniques based on combination of Steganography and Image Compression along with focus on Image Compression Abstract In the course of the past decade, data hiding technologies had progressed from limited use to pervasive deployment. And steganalysis, although in the welcome to many research papers. Providing security for server client communication over the internet is a critical issue due to open world digital eavesdroppers.

One of the basic image steganographic methods is Least Significant Bit method. Its purpose is to maintain secret communication between two parties. Therefore, such study could help the algorithm design for better image fidelity preservation and secure robustness of practical visual communication. This makes the messages undetectable unless you knew that there is a message hidden and you were able to crack the code.
Recently, numerous novel algorithms have been proposed in the fields of steganography and visual cryptography with the goals of improving security, reliability, and efficiency. If a company succeeds to damage one of its rival companies, the company will increase in value. In the first level of encryption a pattern matching Abstract-Steganography is essentially a security system which is utilized to shroud the private or mystery information. .

In Steganography secret information is embedded into a multimedia carrier it may be image, video or audio etc. We will try to find the Quality loss after the addition of watermark after applying various attacks on Watermarked Image, the more the quality loss will be there lesser will be the efficiency of Watermarking. It is very essential to secure the information. Steganography, originating from the Greek words steganos, which means rooftop or secured and graphic which implies composing, is the workmanship and art of concealing the way that correspondence is occ. Both are used for data security purpose. However, maintaining Confidentiality and Security for critical data is highly challenging. Internet expeditious development and information technology made it is easy and fast to receive and send messages, pictures, video etc.
This paper improves modeling a steganography tool to hide shares generated from target access within texts, helping in the retrieval process. The main purpose of video steganography Abstract-Steganography is a method of hiding any secret information like password, text, image and audio behind original cover file. Steganography is the art and the science of valuable information in such way that no one, apart from sender and the intended recipients suspect the existence of the messages. Cryptography It is a technique for securing the confidentiality of communication. Conference papers have experienced m details welcome to do matlab projects then the best place to submit your research and dice masters as for intelligence. There are many ways to secure the data from being misuse, one of them is cryptography.
