Patent ID: 8533793

Claim:
A system for providing security for a protected network resource, comprising: a network access apparatus in communication with a receiver, wherein the receiver receives signals from a remote source, and wherein the network access apparatus is capable of collecting current microprint data for the receiver, the current microprint data being a plurality of values based on data values received at the receiver over a predefined period of time; and an authentication computer in communication with the network access apparatus, the authentication computer having access to an Location Specific Digital Fingerprint (LSDF) for the receiver, wherein the LSDF is a plurality of values based on data values received at the receiver over a predefined period of time, wherein the network access apparatus provides current microprint data for the receiver to the authentication computer, and wherein the authentication computer compares the current microprint data to the LSDF for the receiver to authenticate an access request; wherein the network access apparatus is in communication with a plurality of receivers, each receiver having an associated LSDF accessible to the authentication server; wherein the network access apparatus provides current microprint data for a random sampling of selected receivers of the plurality of receivers to the authentication computer, and wherein the authentication computer compares the current microprint data for each selected receiver to the LSDF associated with each receiver to authenticate an access request.
