  • Patent number: 6603857
    Abstract: A method and apparatus for controlling release of time-sensitive information is accomplished by a server that establishes access information for a specific future time which only becomes active once the specific future time has passed. When the specific future time has passed, the server releases the access information such that an end-user or end-users may utilize the access information to obtain time-sensitive information. The access information may be a random number which can be used to calculate a decryption key and an encryption key. The encryption key can be released by the server at any time such that an end-user may encrypt time sensitive information for release at the specific future time, but the random number is not released until the specific future time has passed. When the random number is released, end-users may generate the decryption key and subsequently decrypt the time-sensitive information.
