Abstract: Systems and methods for identifying fraudulent Internet traffic are provided. A tracking script is provided that generates a unique URL encoding an IP address of a client device. In order to find an IP address associated with the unique URL, a request for the IP address associated with the unique URL is received at a DNS resolver server from a DNS server upstream from the client device. The IP address of the client device, the DNS server upstream from the client device and the DNS resolver server in a database are correlated to obtain information about the Internet traffic to determine the likelihood that the traffic is fraudulently generated.

Abstract: Systems and methods for evaluating trustworthiness for an online transaction are provided. The methods may include providing a detection script to a user device alongside content requested by the user device. The detection script is executable on a web browser or web-based application of the user device and configured to cause the user device to send feedback from at least one sensor on the user device that is accessible by the web browser or web-based application. The system receives the feedback from the user device at a server and evaluates the feedback from the at least one sensor on the user device. The script further allows the server to obtain location information for the user device. The server calculates a trustworthiness factor for the user device based on the obtained feedback and location for the user device.
