Abstract: An improved search operation includes receiving, by a server computing device, an encrypted search query and cleartext metadata associated with the encrypted search query from a client computing device; performing a search using the encrypted search query to generate encrypted search results; and sending the encrypted search results to the client computing device.

Abstract: An improved AR/VR operation includes receiving, by a server computing device, encrypted AR/VR user data and cleartext metadata associated with the encrypted AR/VR user data from a client computing device; getting server data based at least in part on cleartext metadata; encoding the server data; performing an AR/VR process on the encrypted AR/VR user data and the encoded server data to generate encrypted AR/VR results; and sending the encrypted AR/VR results to the client computing device.

Abstract: A method comprises receiving, from a remote device, an audio/video input signal, identifying one or more objects in the audio/video input signal tagged as a sensitive object, evaluating a set of workload requirements for a set of processing workloads comprising portions of the audio/video input signal, selecting one or more heavy processing workloads in the set of processing workloads to send to a compute service provider, in response to a determination that the one or more heavy processing workloads comprises one or more objects tagged as a sensitive object, encrypting the one or more objects tagged as a sensitive object using a homomorphic encryption protocol to generate a first homomorphically encrypted string, and sending the first homomorphically encrypted string to the compute service provider via a privacy protected communication channel.

Abstract: A method comprises receiving, from an input device, an input speech signal, encoding the input speech signal to generate a first homomorphically encrypted string, sending the homomorphically encrypted string to a remote device via communication link, receiving, from the remote device, a reply comprising a second homomorphically encrypted string, decoding the second homomorphically encrypted string into an output speech signal, and outputting the output speech signal on an audio output device.

Abstract: A method comprises receiving, from a remote device, a first encrypted data set encrypted using a first encryption scheme, performing a set of computations on the first encrypted data set to generate a first set of encrypted results, encrypting the first set of encrypted results using a second encryption scheme to generate a second set of encrypted results, sending the second set of encrypted results to the remote device, receiving, from the remote device, third set of encrypted results in which the first encryption scheme has been decrypted, and generating a set of decrypted results by applying a decryption algorithm to the third set of encrypted results to decrypt the second encryption scheme.
