Abstract: A method and system for providing real-time encrypted data alerts over secure networks. The method and system detect the improper duplicate data records and generate alerts that indicate the improper duplication. The systems encrypt the data alerts and transmit them to remote devices over private, secure networks to protect sensitive data contained in the alerts.

Abstract: A method and system for reducing fraud by detecting duplicate financial transactions in a financial transaction processing system. In various embodiments, financial institutions can be alerted when a financial instrument such as a check is being tendered for deposit, wherein a previous deposit for that same instrument had previously been submitted at the same or a different financial institution. The system and method provide for detection of deposits of checks after remote deposit of the same check had been previously performed (for example by submitting a digital image of the check). Deposit of duplicate counterfeit paper checks issued to multiple parties can also be detected and mitigated.
