Abstract
To protect access to information recorded on a light-readable disc, a light-readable disc player provides the user with a unique key each time the user attempts to play the disc. After the user communicates the unique key to a transaction service and satisfies certain preconditions, such as providing payment or account information, the transaction service provides the user with an unlock key. The user communicates the unlock key to the light-readable disc player, which plays the disc only if the user has provided the correct unlock key.
