ENCRYPTED TRIGGER AND ASSOCIATED METHODS |
摘要 |
An apparatus, systems and methods control access to an enhancement within a trigger. A portion of a trigger is encrypted and included within the trigger. The trigger with the encrypted portion is then included within a signal. When it is determined that a signal is received with the trigger, the encrypted portion is decrypted and compared to predetermined criteria. If the decrypted portion meets the predetermined criteria, display of an enhancement within the trigger is allowed. |
