Abstract: Systems and methods for device-to-account anomaly detection are disclosed. For example, device information associated with user account data is queried from a user registry and from an external system. The device information from both sources is hashed or otherwise formatted and compared to determine whether a dissimilarity is present. A difference value may be generated and utilized to determine whether an anomaly is present for device-to-account associations as between the user registry and the external system. Utilizing the difference value and/or historical difference values associated with the external system, one or more actions for correcting the anomaly may be selected and performed.
