  • Patent number: 11316838
    Abstract: A method for transmitting router security information, applied in a router, includes: transmitting, to a terminal requesting to acquire router security information, a generated link of a local area network for transmitting the router security information; receiving an access request initiated by the terminal through a network address to which the link of the local area network is pointed; and, returning, through the local area network, a response to the access request to the terminal, the response containing encrypted router security information. The encrypted router security information can therefore be transmitted by a local network established for transmitting security information by a router. In this security information transmission mode, the possibility of remotely acquiring router security information is eliminated. Moreover, the situation where the router security information is transmitted on the cloud is also avoided, and the security of privacy information of terminal devices is improved.

  • Patent number: 10554760
    Abstract: The present disclosure provides a method and networking equipment for acquiring feature information. It relates to a field of computer and communication technology to acquire the device information using the networking equipment such as a router and to send the device information to other users. The method may include: receiving a network connection request sent from a first terminal device; acquiring device information of the first terminal device in response to the received network connection request; determining the feature information of the first terminal device based on the acquired device information; and outputting the determined feature information.

  • Patent number: 9686819
    Abstract: A method for controlling access to a router is provided. The method includes: transmitting a first connection request for establishing a connection using a visitor identity to a router, wherein the first connection request comprises a user identification of a first terminal device; receiving indication information which is transmitted from a second terminal device, the indication information indicating that access to the router is permitted; and transmitting a second connection request for establishing a connection to the router, wherein the second connection request comprises the received indication information.

  • Publication number: 20170126586
    Abstract: A network control system for controlling a visitor network and a network access security protocol for allowing client devices from accessing the visitor network is provided. The network control system relies on a combination of information retrieved from the client device requesting access to the visitor network and information retrieved from network components that make up the network control system to implement the network access security protocol in an efficient manner that minimizes the need for a user to input a password to access the visitor network.

  • Patent number: 9582587
    Abstract: Indexing and retrieving real time content in a social networking system is disclosed. A user-term index includes user-term partitions, each user-term partition comprising temporal databases. As a post is received from a user, a user identifier, a post identifier, and a post is extracted. An object store communicatively coupled to a temporal database for recently received content is queried to determine whether terms in the post has already been stored. A term identifier is stored in the user-term index with the user and post identifiers. A forward index stores the post by post identifier. Responsive to a search query, the user-term index is searched by the user's connections and the terms. A real time search engine compiles the results of the user-term index query and retrieves the stored posts from the forward index. The search results may then be ranked and cached before presentation to the searching user.

  • Publication number: 20050055365
    Abstract: A method for extracting an attribute occurrence from template generated semi-structured document comprising multi-attribute data records comprises identifying a first set of attribute occurrences in the template generated semi-structured document using an ontology. The method further comprises determining a boundary of each multi-attribute data record in the template generated semi-structured document, learning a pattern for an attribute corresponding to an identified attribute occurrence of the first set in the template generated semi-structured document, and applying the pattern within the boundary of each multi-attribute data record in the template generated semi-structured document to extract a second set of attribute occurrences.
