Latest Patents

Yeager holds a patent for "Systems and methods for authorizing a transaction with an unexpected cryptogram." This patent describes methods for performing timely authorization of digital credential data delivered from a mobile device that lacks access to a local persistently stored permanent cryptographic key. The application executable in the operating system of a mobile device receives a first non-permanent cryptographic key associated with the account from a remote computer system. It stores this key as a local cryptographic key associated with the account. The system generates a response cryptogram using the local cryptographic key without accessing the permanent cryptographic key. It then sends a device response communication from the mobile device to an electronic reader of a POS terminal. This communication comprises an application data protocol unit containing the response cryptogram and an account identifier for the account. Yeager's innovative work in this area has the potential to enhance the security and efficiency of digital transactions.
