Abstract

The disclosed exemplary embodiments include computer-implemented systems, devices, apparatuses, and processes that maintain data confidentiality in communications involving voice-enabled devices in a distributed computing environment using homomorphic encryption. By way of example, an apparatus may receive encrypted command data from a computing system, decrypt the encrypted command data using a homomorphic private key, and perform operations that associate the decrypted command data with a request for an element of data. Using a public cryptographic key associated with a device, the apparatus generate an encrypted response that includes the requested data element, and transmit the encrypted response to the device. The device may decrypt the encrypted response using a private cryptographic key and to perform operations that present first audio content representative of the requested data element through an acoustic interface.
