Gedam Lecturer in Computer Engineering Department, AISSMS Polytechnic, Pune, Maharastra, India ---------------------------------------------------------------------***---------------------------------------------------------------------- Abstract - Digital image security and integrity are the top prioritized issue in today’s information World. Watermarking is a famous technique that is used for copyright protection and authentication. Watermark Should be robust and imperceptible. Digital image watermarking process is to embed information of digital such as an image into digital signal using a strong media QR code. It is very difficult to identify that digital image watermarking has applied to the data This is a competent way to restrict illegal copyrights of Information from interactive multimedia networks.With advanced technology in printing and scanning, creating imitate documents have become an Uncomplicated task, making it very difficult to understand between original and the artificial. So, it is a very big challenge for providing Security and verification of digital data. This paper put forward an idea or intimation to provide an innovative method to verify the digital documents. An advanced method of QR code is bring here, which allow us to embed digital data such as image in QR code. In this paper, we bring up a new technique, where the image is encoded in QR i.e. [Quick Response] Code in encrypted form, so that if a hacker tries to modify or tries to tamper with the data the data then he will be unsuccessful to do that. This is due to; the encryption key is unknown to him except from the authorized person. It is impossible to scan or have access to the encrypted QR code as QR codes are robust.

With developing network and internet technologies and connecting computers into the World Wide Web, databases become available not only for authorize access but for illegal access also.Much more digital data can be accessed to via network now a days.The problem of data protection is one of the most important .The methods of coding and hiding information are well known from ancient times as a cryptography and stegnography. 1. INTRODUCTION A digital watermark is a kind of marker secretly embedded in a noise-permit signal such as an image data. It is typically used to identify proprietorship of the copyright of such signal. "Watermarking" is the process of hiding digital information in a carrier signal the hidden information should, but doesn't need to, contain a relation to the carrier signal. Digital watermarks may be used to prove the authenticity or integrity of the carrier signal or to show the identity of its proprietor. The information to be embedded in a signal is called a digital watermark, although in some condition the term digital watermark means the dissimilarity between the watermarked signal and the cover signal. The signal where the watermark is to be embedded is called the host signal. A watermarking system is usually divided into three prominent steps, embedding, attack, and perception. In embedding, an algorithm obtain the host and the data to be submerged, and produces a watermarked signal. this paper contain QR code and steganography is used to furnish the security to important data. 1.1 QR Code QR codes are 2 dimensional matrix. It allows to store a large volume of unique data. Bar-codes are one dimensional vector. So compare to bar-codes QR codes are having more storage size. QR codes can hold up to 7,089 numeric characters and up to 4,296 alphanumerical letter values as an information. The following figure shows the structure of a QR code.
