Detecting cloaking of websites using content model executing on a mobile device

Abstract:

A mobile device generates a first representation, based on a model, of a first content received by the mobile device from a website. An online system receives the representation of the content from the mobile device. The online system receives a second content from the website and generates a representation of the second content using the model. The online system compares the representation of the first content with the representation of the second content to determine a distance between the two representations. The distance indicates a level of similarity between the first content and the second content. The online system compares the distance between the representation of the first content and representation of the second content to determine if the distance exceeds a threshold distance. If the distance exceeds the threshold distance, the online system prevents other mobile devices from accessing the website.
