US Classification:

385147, 370216, 370248, 370254, 398 1, 398 9, 710104

Abstract:

A method and a system for re-establishing the connection of a network device with a network, using viral communication, are provided. According to the various embodiments, a disconnected network device acts as a simple wireless device and contacts a neighboring network device to obtain configuration information. The request can be forwarded to a network management station (NMS) through one or more neighbors of the disconnected network device. Connectivity is obtained by executing the configuration instructions obtained from the NMS.

Abstract:

A policy-based network security management system is disclosed. In one embodiment, the system comprises a security management controller comprising one or more processors; a computer-readable medium carrying one or more sequences of instructions for policy-based network security management, wherein execution of the one or more sequences of instructions by the one or more processors causes the one or more processors to perform the steps of receiving a set of data regarding a user of a computer network; automatically deciding on a course of action based on the set of data, wherein the course of action may be adverse to the user although the set of data is insufficient to establish whether the user is performing a malicious action; and sending signals to one or more network elements in the computer network to implement the decision.

G06F 11/30

US Classification:

713188, 726 24

Abstract:

An isolation approach for network users associated with elevated risk is disclosed for protecting networks. In one approach a method comprises the computer-implemented steps of determining a user identifier associated with a network device that has caused a security event in a network; causing the network device to receive a network address that is selected from a subset of addresses within a specified pool associated with suspected malicious network users; and configuring one or more security restrictions with respect to the selected network address.

Abstract:

A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.

International Classification:

G06Q 30/06
G06Q 10/08
H04L 9/32

Abstract:

A physical storage vault for physical items of digital twin NFTs is described. A combined listing for a physical item and an NET of the physical item is generated, and the combined listing is output in a user interface at a client device. The user interface includes an option to store the physical item in a physical storage vault. A request is received from the client device to transfer ownership of the physical item and the NFT of the combined listing to a user account. The request indicates that the option to store the physical item in the physical storage vault is accepted. Responsive to the request, transfer of ownership of the NET to the user account is initiated by encoding metadata of the NFT on a blockchain with an identifier associated with the user account and by storing the physical item in the physical storage vault.
