Abstract: Systems and methods are provided for detecting potentially fraudulent online behavior, and for assessing advanced user patterns by the detection of the use of multiple windows or tabs. The method includes collecting behavioral data of a user across windows and/or tabs of a browser of a user device running on or accessing a website, determining the use of multiple browser tabs and/or windows running on the website by associating a foreground process of the browser to a background process of the browser, comparing the collected behavioral data and the determined use of the multiple browser tabs and/or windows running on the website to normal use patterns and fraudulent use patterns, and authorizing the online session based on the comparing indicating a match with normal use patterns or denying the online session based on the comparing indicating a match with one or more fraudulent use patterns.

Abstract: System and methods are provided for client-side web page tampering assessment and fraud prevention by detection of one or more events that are uncharacteristic of user-specific behavior. A method is provided for monitoring a web page Document associated with a Document Object Model (DOM) of a browsing session of a user, capturing one or more event-based mutations of the web page Document, and retrieving, from a profile repository, user behaviometric history data. Responsive to comparing the one or more event-based mutations to the user behaviometric history data, the method can include denying continuation of the browsing session based on a predetermined similarity mismatch of the one or more event-based mutations to entries in the user behaviometric history data and output one or more indications of potential fraud.
