Abstract: Systems and methods are disclosed for protecting data. A device requesting access to the data is required to correctly respond to a challenge embedded in the data provided responsive to a request for the data. If the device that receives the data is able to generate the correct response to the challenge, the device can be validated as the device that was intended to receive the data. When the device is able to generate the correct response to the challenge, the correct response can indicate that the requested data is being used as intended. That is, the challenge can ensure that the context specified in the request, which was deemed an appropriate environment for use of the data by the server that triggered distribution of the data responsive to the request, is, in fact, the context in which the data is actually going to be used.
