Abstract: The disclosed computer-implemented methods and systems provide solutions for mitigating misdetection of display devices in connection with a subscription service. In some examples, the described methods and systems receive a content request from a display device, where the content request is correlated with a particular subscription service account. In some examples, the systems and methods further determine that the display device is not associated with the particular subscription service account. To verify the display device, the systems and methods utilize display timings and scan timings associated with a verification token to prove that the display device is validly located and can therefore be trusted in connection with the subscription service account. Various other methods, systems, and computer-readable media are also disclosed.
