SECURE ACCESS MODULES FOR IDENTITY PROTECTION OVER THE EAP-TLS - Smartcard Benefits for User Anonymity in Wireless Infrastructures

A recording medium for laser writing and a method of making same wherein a silver-halide emulsion coating disposed on a substrate is strongly exposed to actinic radiation and then developed, or otherwise processed for maximum blackness. The black opaque emulsion is converted to a reflective recording medium by heating at least to 270 DEG C. in an oxygen containing environment until the emulsion coating assumes a shiny reflective appearance and the gelatin partially pyrolyzes creating a carbon containing absorptive matrix. Prior to developing, patterns may be photographically imposed on the medium to provide control indicia for the recording system or data base information to a playback system or to provide a means of replicating master recordings.
