    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.

    Abstract translation: 在一个或多个授权设备上启用解密模块。 使用卡验证号码或用户已知的一些秘密来加密用户的财务帐户信息,并将其复制到授权设备上。 用户使用先前加密的金融账户信息请求处理金融交易。 授权设备检索加密的金融账户信息,并提示用户输入卡验证号码(或用于加密金融账户信息的用户已知的其他秘密)。 解密模块使用用户输入的卡片验证码对金融账户信息进行解密,解密的金融账户信息类似于有效的信用卡或借记卡号码,并通过Luhn测试。 发送解密的金融账户信息以处理由用户发起的金融交易。
