Latest Patents
One of Qiu's latest patents is titled "Method and system for detecting fraudulent user-content provider pairs." This invention relates to identifying fraudulent content provider-user device pairs. In this system, an initial user risk value and an initial content provider risk value are determined. A first functional representation of a user risk value is generated based on the initial user risk value and relational data. Additionally, a second functional representation of a content provider risk value is created based on the initial content provider risk value and the relational data. The system then determines a converged user risk value and a converged content provider risk value associated with the first and second representations converging. Ultimately, a pair risk value is established based on these converged values, allowing for the application of a fraudulent label to interaction events detected by the content provider from the user when the risk pair value meets certain conditions.
Another significant patent by Qiu is "Method and system for detecting fraudulent advertisement activity." This invention provides a fraud detection system and method aimed at protecting against fraudulent advertisement requests. Upon receiving an advertisement request, the system extracts an identifier associated with the source of the request. It then checks whether this identifier is included in a list of designated identifiers. If the identifier is found in the list, the system denies the advertisement request. Conversely, if the identifier is not included, the system provides the advertisement and extracts a set of features from the request to determine if the identifier should be added to the designated identifiers list based on these features.
