Abstract: In order to control the taking of luggage from an airport baggage claim area, a hand-held electronic luggage match device is disclosed. The device reads barcode information attached to luggage and barcode information attached ticket stubs and automatically detects when a passenger has presented all the matching ticket stubs for retrieving the claimed luggage. When a passenger presents all the necessary stubs for all the luggage pieces claimed, a green light and a beep indicate proper verification. The event of luggage pick-up is then logged and time-stamped by the device for future reference.

Abstract: The present invention is a secure data entry and visual authentication system that allows a user to securely input and communicate data, including passwords. The system includes a client subsystem (100), a server subsystem (200) and a communication subsystem (300). Server subsystem (200) generates a pseudorandomly arranged display image (250) including a plurality of icons associated with data, and transmits said display image to client subsystem (100) for display on a display device (104). A user consecutively selects at least one said icons corresponding to data desired to be input. Selected icon location information for those selected icons is communicated by client subsystem (100) to server subsystem (200), which then compares that selected icon location information to icon location information and associated data stored in memory (210) to ascertain the data input by the user.

Abstract: A computer server program is disclosed that can execute object code provided by one or more clients even though the server was not previously programmed to execute specific code. The server executes the client code without re-compiling or re-linking. Clients provide the server with executable object code along with information about the code that allows the server to register the code object. By manipulating the registration information stored on the server, the clients can make various requests of the server which affect the execution of the code. Using the registration and request functions of the server, clients direct the server when, if, and how often to run object code or parts of object code called functions.
