Methods and systems for multi-factor authentication

A system for multi-factor authentication, the system associated with a device, comprising:

• at least one memory;
• and
• one or more hardware processors, the at least one memory coupled to the at least one processor, wherein the at least one processor is capable of executing programmed instructions stored in the at least one memory to:
• facilitate a receipt of an audio input at the device, the audio input being one of a speech utterance and a pre-recorded audio content;
• facilitate a receipt of a plurality of authentication parameters at the device, an authentication parameter from the plurality of authentication parameters being received from one of the device and a server communicably coupled to the device;
• encrypt the plurality of authentication parameters to generate a plurality of encrypted authentication parameters;
• embed the plurality of encrypted authentication parameters as watermarks into the audio input to generate a watermarked audio signal;
• and
• encrypt the watermarked audio signal to generate an authentication audio signal,
• wherein, the authentication audio signal being transmitted to an authentication server over an audio communication channel to authenticate the access at the device.

A non-transitory computer-readable medium having embodied thereon a computer program for executing a method for multi-factor authentication to authenticate an access at a device, the method comprising:

• facilitating a receipt of an audio input at the device, the audio input being one of a speech utterance and a pre-recorded audio content;
• facilitating a receipt of a plurality of authentication parameters at the device, an authentication parameter from the plurality of authentication parameters being received from one of the device and a server communicably coupled to the device;
• encrypting the plurality of authentication parameters to generate a plurality of encrypted authentication parameters;
• embedding the plurality of encrypted authentication parameters as watermarks into the audio input to generate a watermarked audio signal;
• and
• encrypting the watermarked audio signal to generate an authentication audio signal, wherein, the authentication audio signal being transmitted to an authentication server over an audio communication channel to authenticate the access at the device.

A processor-implemented system for multi-factor authentication, the system associated with an authentication server, comprising:

• at least one memory;
• and
• one or more hardware processors, the at least one memory coupled to the at least one processor, wherein the at least one processor is capable of executing programmed instructions stored in the at least one memory to:
• receive, at the authentication server, an authentication audio signal data from the device, the authentication audio signal data comprising an encrypted watermarked audio signal;
• decrypt the encrypted watermarked audio signal to obtain a watermarked audio signal, the watermarked audio signal comprising an audio input watermarked with a plurality of encrypted authentication parameters, the audio signal being associated with a user of the device:
• perform speaker verification on the watermarked audio signal to verify the user of he device;
• extract, upon verification of the user of the device, a watermark comprising the plurality of encrypted authentication parameters, from the watermarked audio signal;
• and
• verify the plurality of encrypted authentication parameters based on a comparison of the plurality of encrypted authentication parameters with corresponding pre-stored plurality of authentication parameters, wherein verifying the plurality of encrypted authentication parameters facilities authentication of the access at the device.
