Double-interface portable memory devices for keeping secrecy

Abstract

The invention relates to a double dielectric sides portable secret storage device, which comprises double dielectric sides portable secret storage device and host machine end double dielectric sides connecter which has two different dielectric sides: data transmitting dielectric side and identification dielectric side used to ascertain the transmitting of user's identification. The invention increases a dielectric side on transmitting process and uses the dielectric side to ascertain user's identification to bring down the rate of non-user stealing inner data.

Description

technical field [0001] The invention relates to a dual-interface portable security storage device, which utilizes a double-interface confirmation method to carry out security measures on the portable storage device. Background technique [0002] USB is the abbreviation of Universal Series Bus (Universal Bus), which is a serial standard interface for information products that is commonly used around the world. It is currently mainly used for the connection between PCs and their peripheral devices. In addition to supporting slow data transmission (such as mouse, keyboard, joystick, etc.), USB also supports fast digital compression audio and video information transmission. It has two pairs of wires (4 wires), which are used to transmit data signals and provide them to peripherals. The power supply required by the device can form a star network through the USB hub (Hub) and the root hub (Root Hub) inside the computer, and as the number of hubs increases, the size of the network ...
