Geolocation error tracking in transaction processing

An improved technique tracks errors in collecting geolocation data associated with a transaction. Along these lines, an adaptive authentication engine stores information indicative of a failure to collect geolocation data associated with the transaction. In particular, this information takes the form of a geolocation collection state; the adaptive authentication engine stores such a state in a field of a database that contains historical transaction information. If a service provider failed to collect geolocation information for a transaction, the adaptive authentication engine stores a "Fail" value in the geolocation collection state field of the database entry associated with the transaction. Adaptive authentication techniques may then correlate such "Fail" values with other field values such as time of submission and device type. The result of such a correlation is to build a risk model based on geolocation collection error which the risk engine may then use to compute risk score.
