1. A computer system providing for selectively secure communications between tier participants in execution of a multi-tier, multi-program incentive rewards management system, said computer system comprising:
a) a computer server system operative to concurrently implement a plurality of defined incentive reward programs, wherein each said defined incentive reward program is defined with respect to a plurality of tier participants wherein each said tier participant is a participant in a supply chain defined relative to predetermined purchasable items, wherein said supply chain is associated with a plurality of tiers defined by cooperative functions in the implementation of said supply chain, wherein each said tier participant is associated with a corresponding one of said plurality of tiers, wherein said computer server system is further operative to transmit incentive reward program messages to said plurality of tier participants through a communications network; and a) a plurality of client computer systems associated respectively with said plurality of tier participants and operative to receive incentive reward program messages from said computer server system, wherein each said client computer system includes a key store providing persistent storage of a plurality of encryption keys including first and second encryption keys, wherein each said c client computer system executes an application program operative to apply said first encryption key to first decrypt incentive reward program messages having first and second parts, wherein said first decryption of said first part provides first part clear text, and wherein said first decryption of said second part provides second part encrypted text, wherein said application program is further operative to apply said second encryption key to said second part encrypted text to provide second part clear text provided said second encryption key corresponds to said second part encrypted text, wherein said second encryption key corresponding to said second part encrypted text is selectively distributed to said plurality of client computer systems dependent on a defined association of said tier participants with said plurality of defined incentive reward programs. |
