Abstract
Systems and methods for multi-dimensional voice-based digital authentication are provided. Methods include receiving, at a central server from a remote user device, a request to access a protected digital resource; displaying a prompt, at the device, requesting a spoken password expression; capturing, at the device, an expression spoken in response to the prompt; determining that the expression satisfies predetermined attributes of the password expression; calculating a voice pattern representation of the expression; determining that the voice pattern representation of the expression satisfies a threshold similarity to a voice pattern representation of the user that is stored in a database at the central server; and, in response to the expression satisfying the predetermined attributes of the password expression and satisfying the threshold similarity to the voice pattern representation of the user that is stored in the database at the central server, authorizing the device to access the protected digital resource.
