WATERMARKING SCHEME BASED ON MOST SIGNIFICANT BIT FOR PUBLIC COPYRIGHT PROTECTION FOR RELATIONAL DATABASES

Abstract

The paper presents a watermarked scheme based on the most significant bit for public copyright protection for relational databases. A Watermark scheme could openly prove data copyright as often as desired. This watermark scheme is stable against common attacks such as adding, editing, and deleting data values randomly or selectively.
