US Patent:

6728881, Apr 27, 2004

Filed:

Oct 1, 1999

Appl. No.:

09/413061

Inventors:

Somayajulu Karamchetty - Columbia MD

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

G06F 126

US Classification:

713186, 713182, 713185, 713189, 713193, 713200, 713201

Abstract:

An authorization system uses card and signature devices to provide access to a machine. The devices include capacitance grids positioned on different surface regions of the devices to convert fingerprint images of at least two fingers into electrical signals. An images processor in the device processes the electrical signals detected from the fingerprints to produce electrical images of the users fingerprints. The devices store fingerprint and encrypted user identification data. An authenticating processor compares the users fingerprints detected on the capacitance grids with authorized users previously recorded fingerprints and the users name and identification data to produce an authenticating signal if there is a match of the fingerprint images. Signature storage and identification can be provided to store and authenticate the usess electronic signature.

International Classification:

G06F 12/14

US Classification:

711115, 711102, 711103, 711104, 711163, 711164

Abstract:

A computer system and method for securely storing data are provided. A Radio Frequency Identification Device (RFID) tag is applied to a removable data storage device that is able to be inserted and removed from the computer system. An identification code is assigned to respective removable data storage devices in which the identification code and other information associated with the removable data storage devices are stored at the computer system upon insertion and retrieval of the removable data storage devices to and from the computer system.

International Classification:

G06F 314

US Classification:

395334

Abstract:

A natural computational system and environment replaces domain-specific centional application programs by allowing the juxtaposition of text, graphs, tables, equations, and sketches while concurrently permitting the use of these computational features in calculations and other problem-solving procedures, allowing non-programmers to develop computational schemes and obtain solutions to domain problems in a natural manner, with little or no code development, using familiar representational schemes presented to the user with the same functionality as is provided by a textbook or handbook. Each of the features is made up of a plurality of objects in a hierarchical scheme which permits development and use of the features in a completely natural and flexible manner. The system and environment thus permits the development of electronic textbooks, handbooks, and catalogs in which the text and features are simultaneously displayed, but which permits interactive use of the features.
