US Patent 10333707 Systems and methods for user authentication

Systems and methods for authenticating an electronic transaction are described. A request to complete an electronic transaction is initiated using a third party application installed on a computing device. The third party application receives, from a remote server, a temporary URL including a token. A background application installed on the computing device decrypts the token. The computing device displays details of the request provided by a user of the computing device and prompts the user to provide biometric information to verify the request. A biometric hardware device in communication with the computing device receives biometric information and passes it to a hardware abstraction layer of the computing device, which maps the biometric information to generate a key. The background application encrypts the key and sends the encrypted key to the remote server. The computing device receives a verification result for the request, e.g., via the third party application.
