Objective:-
The purpose of the project is
à To add the watermarks to the image inside to hide the data from the unauthorized persons.
à To Provide copy right Protection for the Documents.
Introduction :-
Watermarking can be defined as an act of embedding a message i.e. a text or an image into a existing work .
(or)
Watermarking can also be defined as an invisible signature.
More recently, different watermarking techniques and strategies have been proposed in order to solve a number of problems, ranging from the detection of content manipulations, to information hiding (steganography), to document usage tracing.
Why Watermarking ?
Security of multi media communications is regarded by both academy and industrial research as one of the most important and urgent problems of last decades.
Watermarking is the art of imperceptibly embedding a message into a work. More recently, different watermarking techniques and strategies have been proposed in order to solve a number of problems, ranging from the detection of content manipulations, to information hiding (steganography), to document usage tracing.
The possibility of adding several watermarks to the same image would enable many interesting applications such as multimedia document tracing, data usage monitoring, multiple property management.
Existing System :-
In the existing system we used single watermarking concept. In this concept overwriting applied only one time. So, it has some low security. In the Traditional (and Conventional) method of Watermarking, the Watermark is made during the paper manufacturing process. Once the water marking has been applied to the paper then we cannot change it or overwrite it, which makes insecure in the water marking technique.
Existing System Disadvantages :-
Minimum Order Quantity is HUGE (Typically Larger Than 30 Tons of Paper)
Paper Mill has to recover the cost of the Dandy Roll, which is very expensive to make
INCONSISTENT Positioning of the Watermark across all the Sheets
Proposed System :-
Here we are providing multiple watermarking concepts, such as the sample image overwrite more than one time on the original image. Its robustness against standard image degradation operations has been extensively tested and its security under projection attack has also been proven even though the envisaged application refers to a collaborative environment, in which malicious attacks are not a critical aspect.
Proposed System Advantages :-
• In this scheme we use multiple watermarking.
• We can implement text based, image based, passcode based.
• We can watermark even after manufacturing of paper.
• The encryption is done by symmetric key cryptographic algorithm that is fast and inexpensive.
Modules :-
This project contains four modules. They are:
Preprocessing
Resolution Hiding
Watermarking
Security providing
Briefly about Modules :-
Preprocessing :-
Preprocessing is nothing but the color enhancement where the quality of the picture is increased. The quality can be varied by using the parameters like contrast, Brightness/Gamma, Saturation, etc
