Abstract: Systems and methods for a multiple value packing scheme for homomorphic encryption are described, including at a server, generating a plurality of encrypted payloads, each having a plurality of data values; and at a client, receiving each of the encrypted payloads having the plurality of data values; and multiplying one or more of the data values of one of the encrypted payloads by one or more other data values in one or more of the other encrypted payloads, to generate a product that represents the summation of data values corresponding to the multiplied one or more data values of the encrypted payloads and the one or more of the other data values in the one or more other encrypted payloads.

Abstract: A computing device receives voice input that includes first voice input from a first user and second voice input from a second user. The computing device may determine, based at least in part on the received voice input, a change in possession of the computing device. The computing device may determine, based at least in part on the first voice input and the second voice input, delegation of the computing device from the first user to the second user. The computing device may, in response to determining the change in possession of the computing device and the delegation of the computing device, change at least a level of access to functionality of the computing device from a first level of access to a second level of access.

Abstract: Methods and systems are provided for concealing identifying data that may be used to identify a beacon or device in broadcasts unless an observer device is able to directly or indirectly, via an authorized resolver device, translate an encrypted broadcast into the identifiable information. The wireless security scheme disclosed herein also pertains to resolving the concealed data messages to obtain the identifiable information.
