Filed:

Sep 29, 1998

Appl. No.:

09/163087

Inventors:

James Weldon - Boulder CO
Hilary S. Lackritz - Cupertino CA
Jerry Smith - Littleton CO
Mark McLaughlin - Baton Rouge LA
J. Bradford Merry - Annapolis MD

Assignee:

Hide Seek Technologies, Inc. - Akron CO

International Classification:

G11B 700

US Classification:

369 5321, 369 471, 369 84

Abstract:

A method and system is disclosed for purposefully modifying the accessibility of information encoded upon an optical medium for indicating a state or history of the optical medium and/or a state or history of an item associated therewith. In one embodiment, the optical medium is purposefully damaged when the information is initially accessed so that upon subsequent access attempts of the information on the optical medium, a previous access of the information is detected by the purposefully induced errors. Thus, there is provided an effective technique for limiting illegal duplication and/or use of, e. g. , software, movies, and music on compact disks and digital versatile disks. The present invention provides verification of persons and/or financial transaction cards during financial transactions. In another embodiment, a compact data storage device is disclosed having the approximate dimensions of a credit card that is capable of storing large amounts of data (e. g. , 50-100 Megabytes).

International Classification:

G06F 17/50

US Classification:

716 18, 717140

Abstract:

A method of integrating a High-level Language (HLL) function with a Hardware Description Language (HDL) representation of a circuit design can include identifying an attribute of the HDL representation of the circuit design that is resolved at compile time and determining a value for the attribute using an HLL function when compiling the HDL representation of the circuit design.

Assignee:

Hide and Seek Technologies L.L.C. - Nederland CO

International Classification:

G11B 700

US Classification:

3692751

Abstract:

Data storage media for use with optical scanning machines are adapted to limit access to information stored thereon. Optical disks are used in an optical readout system of a computer to limit continual access to stored data by the optical readout system. A method is provided for limiting access to data stored in an optical media environment.
