A distribution control system is provided to support the controlled and
selective changing of utility for a target. The target with controlled
utility may be an electronic device, or alternatively, may be a tangible
media, such as an optical disc. The distribution control system has a
target with a change effecting device and a restricted access key. An
activation device retrieves or generates an authorization key, and sends
the authorization key to the target. The authorization key may be sent to
the target wirelessly, for example, using a radio frequency signal. The
target has logic that uses the restricted access key and the
authorization key to change the utility of the target. In one example,
the activation device retrieves the authorization key from a network
operation center (NOC) by sending a target identifier to the NOC, and the
NOC retrieves the authorization key for the identified target. The
activation device may also connect to other systems for obtaining
approval to change the utility of the target. For example, the
authorization key may be sent to the target upon receiving payment,
password, or other confirmation.
