Abstract: Disclosed are systems and methods for verifying data containing user-submitted information. Information entered into a form may be transmitted to a service provider associated with a transaction involving the user. The service provider may use a verification service implementing various data review and verification techniques described herein. Devices of the verification service may obtain public and private records about the user from one or more external databases. The devices of the verification service may identify which portions of information pertain to the user and the submitted data elements, and then determine whether the information in those submitted data elements matches with the records of the external databases. The devices of the verification service may generate a response in real-time (i.e., as the user is entering data in the capture form) or after the user completes the data element capture form.
