Abstract
A payment system determines a required level of authentication for a payment transaction by a candidate consumer, based on a correlation with transactions by other consumers related to the candidate consumer, identified for example from one or more social networks. The correlation may be based on geographical location, time and/or type of transaction. A high correlation may indicate a group activity which requires a lower level of authentication.
