Abstract: A digital watermarking for relational databases algorithm  based on nonnumeric field is proposed.This algorithm is good at embedding much more information and doesn’t  need original database in the recover progress.Experimental results show that this algorithm is safe and effective to prevent subset-attack and add-attack.

Key words: digital watermarking, digital watermarking for database, nonnumeric field
