CPC Class H04W

A request message requesting a service is received from a terminal device. Computer code is transmitted to the terminal device, and a communication connection request is received from the terminal device in response to running the computer code on the terminal device. In response to receiving the communication connection request, a communication connection is established to the terminal device. A first IP address associated with the terminal device is determined based on one or more communications transmitted through the communication connection.

Techniques are described for generating semi-random private transaction identifiers for users that are meaningful to data providers and can be used by data providers to perform internal queries for user data. A user provides input to an identity management service indicating the user's consent to link their user account at the identity management service to one or more data providers. The identity management service stores a group blinded transaction identifier (GBTI) based on transaction identifiers generated by one or more data providers. When the user desires to obtain a service from a service provider, the user obtains GBTI-derived value from the identity management service and sends it to the service provider. The service provider sends the GBTI-derived value (and possibly other information) to the data provider to prove that it has the user's consent to obtain desired data or insights about the user but without infringing the user's privacy.

Example computing devices described herein enable computation of a machine learning model on distributed multi-party data that is vertically partitioned, in a privacy preserving fashion. The computing device computes at a party a sum of local data owned by the party, wherein the local data is vertically partitioned into a plurality of data segments, each data segment representing a non-overlapping subset of data features; transforms a cost function of a data analytics task to a gradient descent function, wherein the cost function comprises a summation of a plurality of cost function values; anonymizes aggregated data shards received from a mediator; updating local model parameters based on the aggregated data shards; and performs privacy-preserving multi-party analytics on the vertically partitioned local data based on a learned global analytic model. It leverages a secure-sum protocol that provides strong security guarantees against collusion and prior-knowledge attacks.

Embodiments include apparatuses, methods, and systems including a wireless display system with a secure back channel to transmit an input from an input device coupled to a display receiver device to a display transmitter device. An input from an input device may be captured by a display receiver device in a secure execution environment. Furthermore, the captured input may be transmitted through a back channel to a display transmitter device in a secured form based on one or more secure parameters negotiated with the display transmitter device. The display transmitter device may receive the input in the secured form, decrypt the input in the secured form based on the one or more secure parameters to obtain the input, and further supply the input to an operating system or an application to operate on the display transmitter device. Other embodiments may also be described and claimed.

A method, an apparatus, and a device for managing authentication data of a station (STA), where the method includes determining, by a first wireless local area network (WLAN) controller, that a first access point (AP) is an edge AP when a first STA associates with the first AP, where the edge AP is an AP neighboring to another AP, and the other AP and the edge AP are respectively managed by different WLAN controllers, and sending, by the first WLAN controller, authentication data of the first STA to at least one WLAN controller in order to resolve a problem that system performance is affected because relatively much signaling is required by processing when a WLAN controller synchronizes authentication data of a STA when the STA associates with an AP.
