a multiple audio watermarking algorithm for database based on blind source separation is presented.The watermarking
a mixture of the speech signals of multiple copyright owners is inserted into database.After multiple watermarking is extracted
the speech signals of copyright owners will be separated by blind source separation algorithm based on maximum signal noise ratio.The speeches are matched by speech recognition technology based on DWT algorithm in order to prove that speeches are owned by multiple copyright owners.
