  • Encrypting financial account numbers such that every decryption attempt results in valid account numbers
    Patent number: 10275766
    Abstract: A decryption module is enabled on one or more authorized devices. A user's financial account information is encrypted using a card verification number, or some secret known to the user and replicated onto the authorized devices. The user requests processing of a financial transaction using the previously-encrypted financial account information. The authorized device retrieves the encrypted financial account information and prompts the user to enter the card verification number (or other secret known to the user that was used to encrypt the financial account information). The decryption module decrypts the financial account information using the card verification number entered by the user, and the decrypted financial account information resembles a valid credit card or debit card number and will pass a Luhn test. The decrypted financial account information is transmitted to process the financial transaction initiated by the user.
