  • Patent number: 11343273
    Abstract: The invention discloses a method of reducing Denial of Service (DoS) attack in an Internet of Things (IoT) system. The method provides real time communication between a sender node and receiver node by multiplexing control channel (that uses voice traffic) and data channel (that uses internet protocol traffic). Further an IoT system is disclosed. The communication channel between the sender node and the receiver node is configured to divide into a control channel to perform a handshake to the receiver node and data channel to carry data. Also to prevent DoS attack ports are changed periodically using the control channel. The advantages include reduced DoS attack in the network, low memory footprint of less than 2 KB and the communication is real time. The system and method may be used in commercial IoT deployments like environmental monitoring, smart grid, smart cities and health care.

  • Publication number: 20070130347
    Abstract: A system for harvesting information from network-based sources for a user has a network-connected server with software stored on and operable from a data repository accessible to the server, a user profile stored in the repository, comprising identification of network information sites storing information personal to the user, user ID for enabling the server to log in to the sites on behalf of the user, and one or more report algorithms associated with pre-defined user requests. The server, executing the software, upon receiving one of the pre-defined requests from the user, visits and gathers information from one or more sites indicated in the user profile, and presents a report to the user comprising the information gathered, formatted according to the report algorithm associated with the user's request.

  • Publication number: 20050034055
    Abstract: An Internet-connected portal system has a data repository, a data-gathering system, a request processor, a plurality of report algorithms, and a report processor. The request processor receives a request from a user and matches the request to an individual one of the report algorithms. The data-gathering subsystem accesses plural Internet sites associated with the user and extracts raw data therefrom according to needs of the report algorithm. The report processor processes the raw data according to the report algorithm into metasummarized information defined by the report algorithm, and the portal system transmits the metasummarized information as a report to a destination associated with the report request.
