Abstract
A digital signal processing apparatus, a digital signal processing method, an information center, and a data delivery system are capable of judging reliably whether digital signals such as music data signals recorded on a storage medium have been legally purchased by a customer from a legitimate vendor, so that only when the digital signals are judged to be legitimately purchased data, will a new service be offered to the customer.
