Abstract:
A data access system is provided including a processor, an IC card reader and writer coupled to the processor and including an IC card receptacle, and an IC card which is insertable into the IC card receptacle and which has a memory which includes video data to be accessed by the processor. The processor includes security level data determining the level of encryption of said video data. In another embodiment of the invention, one IC card with two separate integrated circuits embodied within is provided, each of the separate integrated circuits being separately accessible by an IC card reader and writer.
