Patent number: 11316838Abstract: 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.Type: GrantFiled: March 30, 2020Date of Patent: April 26, 2022Assignee: BEIJING XIAOMI MOBILE SOFTWARE CO., LTD.Inventors: Guizhen Yang, Yufang Li, Daokuan Liu, Dian Fan

Publication number: 20170126586Abstract: 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.Type: ApplicationFiled: July 6, 2016Publication date: May 4, 2017Applicant: Xiaomi Inc.Inventors: Yong Chen, Yincheng Xu, Guizhen Yang, Weiyang Chen

Patent number: 9582587Abstract: 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.Type: GrantFiled: September 6, 2016Date of Patent: February 28, 2017Assignee: Facebook, Inc.Inventors: Akhil Wable, Hong Yan, Spencer G. Ahrens, Yofay Kari Lee, Guizhen Yang
