Abstract
Methods, systems and computer program products are provided for controlling the disclosure time of information by a publisher to one or more recipients. A trusted body generates an asymmetrical key pair for a specified date and time of disclosure with an encryption key and a decryption key. The trusted body provides a digital certificate signed with a private key of the trusted body providing the publisher with the encryption key prior to the specified date and time. The publisher uses the encryption key to encrypt data and a recipient obtains the encrypted data at any time prior to the specified date and time. The trusted body then makes the decryption key available to the recipient at or after the specified date and time.
