A modem and secure communications method for the modem is disclosed in which the modem is capable of storing identifying indicia unique to the modem. The identifying indicia may include graphics data such as an image of a credit card, a signature, and/or an account holder to assist in user authentication. Software stored in the modem enables transmission of the identifying indicia to a communication line. Additional embodiments and variations are also disclosed.

Secure transaction modem storing unique indicia

A portable computer or a similar electronic device having a wireless data communication device such as a Bluetooth transceiver is provided with a power down procedure activated by a remote control device. For example, a single key remote control device emits a radio frequency signal bearing a power down control signal that is transmitted to the portable computer. The control signal is received by a receiver separate from the wireless communication device and initiates a power down process that first causes the portable computer to wake up from a sleep state, if the computer is in a sleep or similar state. The communication device or the computer then invokes a driver that either directly initiates a power down sequence or that invokes another program that initiates a power down sequence. A log file is written during power down that indicates the state of the computer at the time that the power down control signal was received.

Apparatus and method for remotely powering-down a wireless transceiver

The present invention is embodied in a system and method for protecting an electronic device connected to a telephone line. The system includes a detector, sensor and protector. The detector determines a resistance built-in to the telephone line, the sensor utilizes the resistance of the telephone line to determine if the telephone line is a digital line and the protector prevents the electronic device from prolonged connection with the telephone line if it is a digital line.
