US Patent 10097583 Non-blocking automated agent detection

Online retailers may operate one or more services configured to detect requests generated by automated agents. A CAPTCHA may be transmitted in response to requests generated by automated agents. The CAPTCHAs may be included in a modal pop-up box configured to be displayed by a client application displaying a webpage to a customer of the online retailer. Automated agents receiving the CAPTCHAs may not be blocked or otherwise restricted from the resources requested and therefore may not be configured to interact with the CAPTCHAs contained in the modal pop-up box.
