ABSTRACT: This paper demonstrates an information covering technique that utilizations lifting arrangements to effectively cover information in shading pictures. Productive information stowing without end should achieve the extraction of the hid data from the photo with abnormal state of data uprightness. Current examples bolster using electronic picture records as the cover archive to hide another propelled report that contains the secret message or information. Particular surges of cutting edge media can be used as a cover stream for a riddle message. Stenography is the strength of forming secret messages so that selective the sender and the proposed recipient think about the hid message. This paper introduces a method for riddle message encoding that makes use of wavelets. Wavelets isolate the stream into high and low repeat section parts called purposes of intrigue and examples. 1. INTRODUCTION: Steganography is the specialty of creating riddle messages or covering puzzle pictures so that selective the sender and the arranged recipient think about the covered information. The word steganography is gotten from the Greek words "stegos" implying "cover" and "reasonable" meaning "expressing" describing it as "secured arrangement". Steganography is an information covering framework that utilizations lifting arrangements to suitably cover information (may be a substance or a photo) in shading pictures. Propelled steganography is fundamentally about hiding a record in, or adding a report to, another archive, called the transporter record, to such a degree, to the point that the carrier archive is not adequately changed in accordance with raise question that something may be concealed inside it or appended to it. Steganography changes from cryptography as in where cryptography focuses on keeping the substance of a message secret, steganography focuses on keeping the nearness of a message riddle. Steganography and cryptography are both ways to deal with shield information from undesirable social occasions yet
neither development alone is impeccable and can be exchanged off. Once the proximity of covered information is revealed or even suspected, the purpose behind steganography is not entirely vanquished. The nature of steganography can in this manner be expanded by combining it with cryptography. Steganography is the craftsmanship and investigation of vague correspondence. This is capable through hiding information in other information, thusly hiding the nearness of the conferred information. In picture steganography the information is covered exclusively in pictures. To an incredible degree difficult to perceive, a common cover message was sent over a flimsy channel with one of the periods on the paper containing hid information. Today steganography is generally used on PCs with mechanized data being the bearers and frameworks being the fast movement channels. The steganographic system on hardware arrange exhibits huge potential by techniques for various purposes of enthusiasm, for instance, quick embedding, specific gear dependence and low power use et cetera. Current examples bolster using propelled picture archives as the cover record to cover another electronic record that contains the riddle message information as either substance or picture. Hardware steganographic modules executed in a processor organize like PSoC offer some key increases to the present occasion of programming based steganography structures. In like manner it gives the Introducing rate which is high when appeared differently in relation to the systems in programming range. NECESSITY: In the present day world, information is changed over from paper sort to electronic information. Appropriately, security change in data saving and exchanging is crucial. Unmistakable methods of cryptography are used for data encryption however these strategies can be seen by trespassers. In case the information can be embedded in a medium with the end goal that it can't be recognizable easily, it won't raise the uncertainty of trespassers. This is the crucial considered steganography.

NOVATEUR PUBLICATIONS International Journal of Research Publications in Engineering and Technology [IJRPET] ISSN: 2454-7875 VOLUME 3, ISSUE 6, Jun.-2017 OBJECTIVE: B. DECRYPTION METHOD: In our wander estimation is proposed to hide a puzzle picture inside CVR picture to guarantee the insurance of the photo. Steganography Imaging System (SIS) is a structure that is fit for covering the data inside the photo. The structure is using two layers of security with a particular true objective to keep up data assurance. Using LSB algorithm we are replacing the list significant bit of cover image with a secret image. Fig 3.3: Block diagram of decryption of an image. MOTIVATION: As the technologies have advanced so much. Hence it is very important to take data security into consideration & fast transmission of data as well as any image. Therefore in our proposed system, we are hiding a secret image over a cover image (bmp format) using steganographic algorithm LSB through PSoC kit. PROBLEM DEFINITION: The purpose of our wander is to scramble and unscramble the stego picture. The stego picture is the photo which covers the secret picture over a cover picture using LSB computation and PSoC hardware.
BLOCK DIAGRAM EXPLANATION: Block diagram of steganography isshown in above Fig. advanced pictures, sound documents, video records, content records, executable records and even voice can be utilized as transporter. How much data can be hidden in the carrier depends on thesize of the carrier and the steganography method used to hide the message. PSOC ARCHITECTURE:

Hiding a message with steganography methodologies decreases the likelihood of a message being perceived. After the implementation of this project, it can be concluded that the steganography can be effectively used to hide data or image into another image without any loss. The main advantage of our project is that any size of image can be hided through LSB algorithm with high speed of transmission by using PSoC kit.
