An input device capable of optically communicating with an electronic apparatus is provided. The input device includes a light source, a force sensor, and a controller. The force sensor is configured to sense a force applied to a tip of the input device and generate a first sensing signal corresponding to the sensed force. The controller is electrically connected to the light source and the force sensor, and configured to receive the first sensing signal and control the light source to generate light pulses in response to the first sensing signal according to a predefined protocol.

Input device and display system having the same

A method for preventing unauthorized use of a software program on a computing device includes updating a state of a software program on a computing device to an updated state. Transmitting an update signal from the software program to a hardware token coupled to the computing device and updating a state of the hardware token to an updated state in response to the received update signal. Performing a first cryptographic check using the updated state of the software program and the updated state of the hardware token with the hardware token. Transmitting the first cryptographic check from the hardware token to the software program and performing a second cryptographic check using the state of the hardware token and the state of the software program with the computing device. Comparing the second cryptographic check to the first cryptographic check with the computing device, and preventing the software program from running on the computing device if the first cryptographic check does not match the second cryptographic check.

Locking changing hard disk content to a hardware token

A method for distributing data over a network includes the steps of establishing a secure connection between a client and a server; issuing a certificate and a private key to the client for identifying the client in a transaction; storing the certificate and the private key in a portable token of the client and used by the client during a transaction, the portable token including a unique distinguishing number and being a physical device removeably coupleable to a client computer; and generating a message linking the data being distributed to the client with at least part of the distinguishing number for the token used by the client during a transaction.

Method and system for secure distribution and utilization of data over a network

A method of securely utilizing downloaded data includes the steps of opening a media player; opening a data file; requesting a portable token from and used by a client, the portable token being a physical device removeably coupleable to a client computer; reading a distinguishing number from the token; and verifying a digital message linking the data file to the token using the media player, the distinguishing number, and a private key in the token. The digital message is required to access the data.

A method and apparatus for booting a computer. The method comprises the steps of emulating a floppy disk drive communicatively coupled to a computer in a token via a USB-compatible interface, and booting the computer using the token. The apparatus comprises means for performing these functions, including a token with a processor having one or more memories storing processor instructions and data for performing the method steps. The memory may also securely store sensitive data.
