Systems and methods for verifying a watermark of an AI model for a data processing accelerator

Embodiments of the disclosure relate to verifying a watermark of an artificial intelligence (AI) model for a data processing (DP) accelerator. In one embodiment, a system receives an inference request from an application. The system extracts the watermark from an AI model having the watermark. The system verifies the extracted watermark based on a policy. The system applies the AI model having a watermark to a set of inference inputs to generate inference results. The system sends a verification proof and the inference results to the application.

The processor, based on receiving first ID information and first password information from the external electronic device, is configured to control the electronic device to: acquire at least one candidate ID information from the memory based on the first ID information, compare password information corresponding to each of the acquired at least one candidate ID information with the first password information to identify one of the candidate ID information, and perform user authentication based on the identified candidate ID information and corresponding password information.

Data content chain of custody and integrity validation

A device obtains previously created data content. The device unmasks and extracts one or more chain of custody blocks stored in association with the data content. The one or more chain of custody blocks includes chain of custody data identifying who, when, where, and, with what hardware and/or software, created or edited the data content. The device analyzes the one or more chain of custody blocks and validates an origination of the data content based on the analysis of the one or more chain of custody blocks.

Key-derivation verification in telecommunications network
11582231 · 2023-02-14 · ·

A telecommunications network includes a serving network and a home network. In some examples the serving network receives, from the home network, identity data associated with a network terminal. The serving network determines a tied key using a tying key derivation function (TKDF) based on the identity data, then prepares an authentication request based on the tied key and sends the request to the terminal. In some examples, the home network receives the identity data from the access network and determines a tied key using a TKDF. The home network then determines a confirmation message based on the first tied key. In some examples, the serving network receives the identity data from the home network, and receives a network-slice selector associated with the network terminal. The serving network determines a tied key using a TKDF based on the identity data and the network-slice selector.

Systems and methods to secure searchable data having personally identifiable information

A method implemented in a computing system hosting a three-dimensional virtual reality world. The computer system stores a set of searchable records, each having: a searchable hash of at least a portion of personally identifiable information; and an encrypted identity, decryptable using an encryption key generated based at least in part on the searchable hash and a global key. In response to a search request identifying at least a portion of personally identifiable information as a search criterion, the computer system generates a hash of the search criterion, and finds a matching searchable record that has a searchable hash equal to the hash computed from the search criterion. An encryption key is computed based on the global key and the matched searchable record to decrypt an encrypted identity of a user having at least the portion of personally identifiable information that is the search criterion in the search request.

Vehicle information communication system

A vehicle information communication system includes a center apparatus and a vehicle apparatus that includes a group of electronic control units (ECUs) and that sends vehicle configuration information including configuration information on the group of ECUs mounted in the vehicle to the center apparatus via wireless communications. The center apparatus performs a first determination of whether the vehicle configuration information received from the vehicle apparatus matches approved-configuration information registered in an approved-configuration database, and performs a second determination of whether software update data for at least one ECU of the group of ECUs mounted in the vehicle exists in an update database. When both the first and second determinations are true, the center apparatus sends the software update data for at least one ECU of the group of ECUs mounted in the vehicle to the vehicle apparatus via the wireless communications.

Apparatus and methods for secure distributed communications and data access
11582037 · 2023-02-14 · ·

A secure access control system configured to control access to sensitive data stored on disparate systems is disclosed. A first entity is designated to control access to second entity data. An authentication token, generated using a key derivation function, is used to authenticate the first entity. The authenticated first entity is granted access to second entity data. An access control interface is generated configured to selectively grant or withdraw access to second entity data. The access control interface identifies entities associated with respective access controls. The access control interface is instantiated on a first entity device. Activation indications of access controls is received over a network. Access to second entity data is accordingly granted or withdrawn. Access control transition event rules and/or access control transition time rules are retrieved. Using monitored events and the access control transition event rules, and/or a monitored current time and the access control transition time rules, a determination is made as to transition access control of the second entity data first entity to the second entity.
