  • Patent number: 10074089
    Abstract: The systems and methods described herein allow an electronic transaction to be performed upon determining, via biometric data, that an authorized individual is conducting the transaction. This may involve receiving, by a computer system, a request to authorize an electronic transaction for an account. The computer system is configured to access a phone number, which is stored in computer memory and associated with the enrolled user of the account. An automated and outward call to the phone number is performed by the computer system. The computer system is configured to capture a voiceprint in association with voice data received from the automated call. The captured voiceprint is compared to a registered voiceprint, which is stored in the computer memory in association with the enrolled user. The computer system responds to the request to authorize the secure electronic transaction based on said comparison.
