A New Technique for Relational Database Protection Using Digital Watermarking

Tarun Dhar Diwan, Vinay Sahu

Abstract


In watermark embedding database is embedded into image. Here first we store binary data of image in one data structure (suppose array) and database content in other array. Then copy content of image and database in third array. Watermarking algorithm which is used to recover a database from updated value. This is a web based watermarking technique, in which if software is stored in server then we can access it from client system. Digital watermarking can be used to embed various types of data, depending on the particular application and intended use. For example, a watermark in a digital movie file might simply identify the name or version of the movie. Alternatively, it might convey copyright or licensing information from the movie’s creator. Or it might embed a customer or transaction number that could be used to identify individual payment or transaction data relating to that particular copy of the movie. But the number of bits that can be contained in a watermark itself today is typically modest enough to provide some basic codes or identifiers.

Keywords


Binary Data, Transaction Number, Parser, Hybrid Methods, Automatically.
