Houping Xiao has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10305921
    Abstract: A network security apparatus includes a packet detector detecting transmission of data packets between a plurality of hosts and a plurality of domains and defining a plurality of links therefrom. A model builder circuit receives the plurality of links from the packet detector, receives ground truth information labeling one or more of the plurality of hosts or one or more of the plurality of domains as benign or malicious, generates predictive models from the received links and ground truth information, and stores generated predictive models in a predictive model database. An anomaly detector circuit retrieves the generated predictive models from the predictive model database and uses the predictive models to label each of the plurality of hosts and plurality of domains, that have not previously been labeled by the ground truth information, as benign or malicious.

  • Publication number: 20170060652
    Abstract: In one embodiment, a computer-implemented method includes observing one or more entities by way of two or more data sources. A plurality of detection scores are computed by one or more detectors. Each detection score corresponds to an entity of the one or more entities, a detector of the one or more detectors, and a time. The plurality of detection scores are compiled into two or more tensors, where each tensor corresponds to a data source of the two or more data sources. The two or more tensors are compared to one another, by a computer processor. An inconsistency score is calculated for each of the one or more entities, based on comparing the two or more tensors to one another.
