Technologies for authenticated audio login by a user of a computing device include generating a security token having a plurality of token characters. The computing device renders the generated security token to a current user of the computing device on an output device of the computing device. The computing device, receives security token audio input from the current user and retrieves, based on the rendered security token, voice profile data of an authorized user of the computing device from a voice profile database. The voice profile database includes voice data based on the authorized user's prior recitation of each token character of a set of token characters from which the security token may be composed. The computing device compares the received security token audio input and the retrieved voice profile data to verify that the current user is the authenticated user and the current user recited the rendered security token.

Techniques for preventing voice replay attacks

A method, device, and system for secure end-to-end audio recognition is disclosed. A client device launches an application that connects with a server. The client device and server exchange cryptographic keys and establish a secure connection and a shared cryptographic key. The server transmits an encrypted audio prompt to the client device. The client device decrypts the encrypted audio prompt and stores the decrypted audio prompt in secure memory inaccessible to the operating system using an audio engine of the client device. The audio engine then retrieves the audio and renders it for the user through the speakers of the client device. The client device captures the user's audio response with a microphone and stores the audio response in the secure memory. The stored audio response is encrypted and transmitted to the server.

System, device, and method for securing voice authentication and end-to-end speech interaction

A method of adjusting intensity of illumination of a device based on change in ambient light, the method comprising: measuring a first level of ambient light for a device, in response to detecting a change in ambient light; adjusting intensity of illumination for the device to a first illumination level, if an association between the first illumination level and the first level of ambient light is recorded in a data structure; monitoring user interaction with the device within a threshold period after detecting the change in ambient light to determine whether the user adjusts the intensity of illumination for the device to a second illumination level; and recording an association between the second illumination level and the first level of ambient light in the data structure.
