Abstract - Watermarking technology has attracted more and more attention in various research fields Like information security. At this time, we protect the remote sensing data by using watermarking technology. As remote sensing data is delicate, it is necessary to enforce some management for authenticity and ownership. Particularly for the copyright protection, illegal use, and legitimacy identification of remote sensing image data. Therefore, this project proposes to use image watermarking technology to achieve comprehensive security protection of remote sensing image data, although the use of cryptography technology rises the applicability and security of watermarking technology. The remote sensing data is a representation of parts of the earth’s surface as seen from space. The watermarking process is used for hiding digital information. A watermarking is a logo, text, or pattern. That is purposely covered in another image. Its purpose is to make it tougher for the original image to be imitative or used without authorization. Cryptography is the process of protecting information by transforming it into a secure format. Which provides an alternative solution for ensuring tamper resistance, and the ownership of intellectual property. And the tamper recognition will aware you when your device is being restricted by employees or other individual seeks. The untried results show that the arrangement of remote sensing image digital watermarking technology has good performance in the faintness and robustness of watermarking

2.2.1 HISTORY

The tenure "Digital Watermark" was created by Andrew Terkel and Charles Osborne inDecember 1992.Thefirstsuccessfulembeddingand extraction of a steganographic spread spectrum watermark were demonstratedin1993byAndrewTerkel,CharlesOsborne

Watermarksareidentificationmarksproducedduringthe papermakingprocess.The firstwatermarks appeared in Italy during the 13th century, but their use rapidly spread acrossEurope. They stayed used as a resource to recognizethe papermaker or the craft league that industrial the paper.The symbols often werecreated by a wire seamed onto the paper Mildew.Watermarks linger to be used today as producer's symbols and to avoid forgery.

2.2.2 General model for digital image watermark

detected using a watermark detector. During the developmentofembeddingandnoticingwatermarks,apiece called a watermark significant is used. With the advancement of satellite remote sensing technology in recent years, remote sensing images have increasingly reflected their features of fast and easy access. Floating picturesandsatellitepicturesarethemostcommontypesof remotesensingimages,whichgenerallyrecordgeographic, environmental, resource, military, and other information vitaltothenationaleconomyandpeople'sconfrontation.In rapports of land administration, figures show that by engaging satellite images, the time necessary for land mergingiscutinhalfassociatedwithoutdatedmethods,and thecostistensoftimeslesser.

As per the outcome, remote detecting images will play an importantroleinmerging.Currently,remotesensingimages are only employed as a spatial data input system for processing.Theanalysisandprocessingdataarejustsaved as photos to complete the basic electrification.

At the same time, watermarking technology can identify manipulationbyremotelysensingdata.Theaxiom"Digital watermarking" was designed by the inquiry labs, that invented this advanced technology. However, as photographershavebeenutilizing"watermarking"foralong time, this wording causes a lot of confusion in the digital photographyworld.Thesetwotypesof"watermarking"are notsubstitutable

the signal where the watermark will be inserted. Watermarkingsystemsareusuallybrokendownintothree stages:embedding,attack,anddetection.Whenanalgorithm accepts the host and data to be embedded, it creates a watermarkedsignal.

At thatpoint the watermarked fundamental signal is transmitted or kept, usually spread to another person. If this separate modifies, this is called an occurrence Although themodification may notbe mean, the tenure enchantment gets up from copyright protection applications, where tertiaryrevels may try to eliminate the digital watermark complete modification. There are numerous imaginable modifications, for example, a lossyfirmness of the data (in which resolution isdiminished), cropping an image or video, orintentionallyaddingnoise.

Detection (also known as extraction) is a method that attemptstoextractthewatermarkfromtheassaultedsignal. The watermark is still present and can be recovered provided the signal was not altered during transmission.

3.1 EMBEDDING

The way of watermark creation is using a watermarking critical and the watermarking algorithm, to yield the watermarkeddigitalimage.Theinsertingprocessvarybased on which image domain is being processed, e.g., the terrestrial,incidencefield,orthewavelets.Dependingonthe embedding method measurable (single bit) or readable (multi bit) watermarks are being incorporated into the digital images. A watermark implanting technique is a procedure for inserting a watermark into a coverup document.

communication of the information conveyed by the watermark. There are various types of attacks on watermarkingschemes:Basicattacks,RemovalAttacks,legal attacks, Geometric attacks, Protocol Attacks, and CryptographicAttacks.

3.3 BASIC ATTACKS

3.5 REMOVAL ATTACKS

Removal sessions purpose at the complete elimination of thewatermark data from the watermarked datawithout instant the security of the watermarkingalgorithm (e.g., without the crucial used for watermarkembedding).That is, no allowance, even exorbitantly multifaceted, can recuperate the watermark information from the attacked data. This grouping contains denoising,quantization (e.g., for firmness), demodulation,and collusionfits.Not allof these approaches always come close to their goal of complete watermark removal, but they may damage thewatermarkinformationmeaningfully.

3.6 COPYRIGHT ATTACK

Cryptographic attacks aim to break the security methods used in watermarking schemes, allowing the embedded watermark information to be removed or misleading watermarkstobeembedded.
