Volatile memory-based data-transfer device with automatic and user-initiated anti-tamper penalties

摘要

A USB-style data-transfer device employs volatile memory that is connected to an onboard power-storage device for data storage. Through this design, any data stored on the memory can be physically cleared by interrupting the supply of electrical power from the onboard power-storage device to the memory. Enhanced security relative to conventional USB flash devices is provided by the volatile memory-based USB-style data-transfer device as the memory can be physically cleared without being plugged into a computer system either automatically when the onboard power storage device runs out of electrical power to supply to the volatile memory, or by user initiation through either a programmed instruction to interrupt the supply of electric power after a set time period or the operation of a manual switch which interrupts the supply of electric power.
