Authentication using sound based monitor detection

A system comprising:

• at least one hardware processor, and
• a physical memory communicatively coupled to the at least one processor, the memory storing instructions which, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• obtaining an image of a user of a computing device as part of an image-based authentication process of the computing device;
• accessing sound data that is generated by at least one microphone of the computing device, the sound data describing sound that is detected by the at least one microphone;
• generating, based on frequency characteristics of the detected sound indicating presence of sound emitted by a display monitor, prediction information that describes a probability that the display monitor is operating in proximity to the computing device during the image-based authentication process;
• determining, based on the prediction information, that the image of the user is a spoofed image displayed by the display monitor;
• and
• determining, based on determining that the image of the user is a spoofed image, that the image-based authentication process is to be aborted.

One or more non-transitory, computer-readable storage media storing instructions which, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• obtaining an image of a user of a computing device as part of an image-based authentication process of the computing device;
• accessing sound data that is generated by at least one microphone of the computing device, the sound data describing sound that is detected by the at least one microphone;
• generating, based on frequency characteristics of the detected sound indicating presence of sound emitted by a display monitor, prediction information that describes a probability that the display monitor is operating in proximity to the computing device during the image-based authentication process;
• determining, based on the prediction information, that the image of the user is a spoofed image displayed by the display monitor;
• and
• determining, based on determining that the image of the user is a spoofed image, that the image-based authentication process is to be aborted.
