Abstract:
1. A security apparatus system comprising: a verifier apparatus configured to determine an authorization to process protected material to facilitate an assessment of physical proximity of a source of a response based on an assessment of response times associated with one or more responses received from an unknown second source to one or more requests issued from a first source to the unknown second source; a timer apparatus, operably coupled to the verifier apparatus, configured to measure response times between a request for content from a first source and a response from the unknown second source; a memory to store the response times for limiting subsequent access of unauthorized users or notifying an external source of the unauthorized users; wherein each of the one or more requests issued from the first source comprise a request for access to randomly selected source information from the unknown second source; wherein the assessment of the response times forms an assessment of whether the one or more responses were communicated locally to the verifier apparatus or via a network connection; and wherein the assessment of the one or more responses performed by the verifier apparatus comprises: continuously requesting randomly selected source information from the unknown second source unit until a statistically observable difference from an expected response time of a local source is detected; and wherein the one or more responses are stored for limiting subsequent access of the unauthorized users or notifying an external source of the unauthorized users.
