Verification that a user attempting to access content is a human user
Abstract:
An easier and less frustrating way of verifying that a user attempting to access content is a human user is provided. For example, data indicative of a request by a user to access content from a content server is received. An output of geographic data associated with a geographic region is generated. A task to be performed by the user to access the content is provided as a function of the generated output. The output and the task are transmitted to the content server for presentation to the user. Performance of the task by the user is substantially indicative of the user being a human user.
