Integrity protection for relation databases with text data by digital watermarking

Lưu Bích Hương, Bùi Thế Hồng

Abstract


The paper proposes a new watermarking scheme for integrity protection of relational databases with text data. This scheme generates a watermark from the vowels, consonants and special characters of the text attributes then embeds into attributes which are low impact. The embedded characters do not affect much for these attributes but can help for detection any tempering in the relation database.


Keywords


Watermark, non-numeric attribute.
