1. An apparatus, comprising:
a communications interface;
a memory storing instructions; and
at least one processor coupled to the communications interface and to the memory, the at least one processor being configured to execute the instructions to:
receive, via the communications interface, encrypted command data from a computing system, the computing system being configured to generate the encrypted command data based on encrypted coefficient data associated with first audio content;
decrypt the encrypted command data using a homomorphic private key; and
transmit, to a device via the communications interface, an encrypted message that includes an element of data associated with the decrypted command data, the device being configured to decrypt the encrypted message and perform operations that present second audio content representative of the data element through an acoustic interface.
