Abstract:

Techniques and systems for optimizing and cleaning rules for network-based authentication transactions are provided herein. A network-based authentication system may determine a plurality of rules that were previously used to evaluate a plurality of transactions. The network-based authentication system may also generate a false positive rate for one or more of the plurality of rules, A cleaning coefficient for a first rule of the plurality of rules may be generated by the network-based authentication system. Based on the cleaning coefficient and the false positive rate, the network-based authentication system may identify one or more rules from the plurality of rules to eliminate from the plurality of rules. The network-based authentication system may eliminate the one or more rules to generate a modified set of rules. Using the modified set of rules, the network-based authentication system may authenticate a network transaction.
