  • System for transforming user data in accordance with an algorithm defined by design data and for evaluating the transformed data against logical criteria
    Patent number: 5179698
    Abstract: A computer system for processing complex information representative of business transactions. Specifically, the system stores transaction data, which is then reversibly transformed in accordance with predetermined processing algorithms, while it is externally inaccessible. In this static state, the transformed transaction data is evaluated against predetermined logical criteria. The evaluation produces either successful or unsuccessful results. If successful, the transformed data is then made externally accessible. If unsuccessful, the original transaction data is made externally accessible.
