Abstract
Watermarking is one of the effective measures for copyright protection and the integrityof the relational database in the Internet environment. In this paper, we propose a watermarking scheme fortamper detection and localization for renational database. This scheme generates a watermark from the vowels, consonants and special characters of the text attributes then embeds it into low impact attributes. The embedded watermark do not affect much for these attributes but can help for detection and localization of any tempering in the watermarked renational databaseReferences
