Abstract
Technology for providing risk-based authentication, in which a location N-gram is generated for each historical transaction, the location N-gram indicating both a location from which the historical transaction originated and at least one location from which at least one previous transaction performed by the user that performed the historical transaction originated. A counter corresponding to the location N-gram is identified and incremented in a behavior profile for the user. An anomalousness risk score for a current user transaction having the same location N-gram may be calculated based on a value of the counter. If the risk score exceeds a threshold, an alert may be issued or other action taken with regard to the current transaction. Techniques are provided that limit complexity resulting from using a series of locations to detect anomalous user behavior, and that reduce the sparseness of the generated historical behavior data.
