Abstract

A system may obtain a first group of information when an advertising link is requested and a second group of information when the advertising link is selected. The system may further detect illegitimate advertising-related activity based on the first group of information and the second group of information.

Claims

1. A method, performed by a server including one or more computers on a network, comprising:

receiving, by the server, an advertisement query request for an advertising link;

obtaining, by the server, and in response to the advertisement query request, a first group of information related to at least one of;

a browser associated with a client device, a client device to which the advertising link is to be provided, or a user to which the advertising link is to be provided, where the first group of information is obtained before the server receives an indication that the advertising link has been selected;

receiving, by the server, the indication that the advertising link has been selected;

obtaining, by the server, and in response to the receiving the indication, a second group of information related to at least one of;

a browser associated with a client device, a client device to which the advertising link is to be provided, or a user to which the advertising link is to be provided; and

determining a presence of illegitimate activity based on a comparison of the first group of information and the second group of information.

2. The method, performed by the server of claim 1, where the information relating to the browser associated with the client device includes:

at least one of a browser type, a browser version, information identifying whether java is enabled for the browser, information relating to a plugin installed on the browser, a history length associated with the browser, a number of Multipurpose Internet Mail Extensions (MIMEs) associated with the browser, a window width associated with the browser, a window height associated with the browser, a language associated with the browser, a javascript version associated with the browser, or an order of a header of messages transmitted by the browser.

3. The method, performed by the server of claim 1, where the information relating to the client device includes:

at least one of an Internet Protocol (IP) address associated with the client device, a screen size associated with the client device, a screen width associated with the client device, a screen depth associated with the client device, a color resolution associated with the client device, a clock time associated with the client device, a time zone in which client device is located, or a type of operating system running on the client device.

4. The method, performed by the server of claim 1, where the information relating to the user includes cookie information.

5. The method, performed by the server of claim 1, where the first group of information and the second group of information include at least two of:

comparing the first group of information to the second group of information.

7. The method, performed by the server of claim 6, where the comparing further comprises:

determining that illegitimate activity is present when the second group of information does not match the first group of information.

8. The method, performed by the server of claim 1 further comprising:

providing the advertising link in response to receiving the request, the advertising link being provided in association with a document.

9. The method, performed by the server of claim 8, where the advertising link is provided based on a keyword.

10. The method, performed by the server of claim 9, where the document is identified based on the keyword.
