Abstract
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.
