c|net - It used to be that music fans believed cryptic messages about Satan or the death of a band member were hidden within rock albums. Nowadays, the secrets buried in digital music are way too easy to find, according to the Electronic Frontier Foundation (EFF). The consumer watchdog group, which focuses on the Web, claims Apple has left information belonging to customers of the new iTunes Plus service exposed. Music purchased from iTunes Plus is embedded with unencrypted customer names and e-mail addresses. An Apple spokesman declined to comment.
