Problems solved by technology

Taking numerical data in relational databases as an example, watermark information is hidden in numerical data, so the redundant space that can be used to hide watermark information is very limited, so multimedia watermarking technology is not suitable for protecting database data copyright

Embodiment Construction

[0031] The invention provides copyright protection by embedding watermarks in electronic maps in geographic databases. The attributes of the electronic map are divided into non-geographic attributes and geographic attributes. Geographic attribute values ​​represent the coordinate positions of features in a specific coordinate system, and watermark information is hidden in these coordinate values. The non-geographical attributes are mainly the descriptive information of the feature object, which will not be paid special attention here.

[0032] The invention relates to a method and application for protecting database data copyright with digital watermark technology. As shown in Figure 1, the method includes the steps of designing a database watermarking mechanism and implementing the database watermarking mechanism. The invention is widely used, for example, it is used to protect the copyright of geographic databases.

[0033] The present invention will be further described ...

Abstract

This invention relates to digital water print technique protective database authorization method and its application. The method comprises database mode as R(p,A0,A1 to At) plus water print design ad realizes the geography database water print mechanism step on PostgreSQL platform. This invention points to database characteristics to evenly distribute water print information into database under original data.

Description

technical field [0001] The invention relates to the technical field of database security, in particular to a method for protecting database data copyright with digital watermark technology and its application. Background technique [0002] With the increasing popularity of the Internet, the exchange of information has reached an unprecedented depth and breadth, and its release forms have become more abundant, but the problems that have emerged are also very serious, such as the infringement of electronic products is easier, and tampering is also more convenient. As an electronic product, database data has attracted more and more attention to its copyright protection. [0003] The creation process of the database is very complicated, but the copying is extremely simple. If the copyright is not protected, other people directly use the database, and the creator will have nothing to do. In this way, the investment enthusiasm of database creators will be severely frustrated, and...
