A dongle is a hardware-based security device that attaches to the USB or parallel printer port of a computer. It is a hardware key that uses codes and passwords embedded inside the key to control access to software applications. A software program intergrated with a dongle will only run when that dongle is attached to the computer. |
Most dongles are fully transparent, which means a printer cable or other dongles can be attached together in a "daisy-chain", without interfering with the dongles functionality or information exchange. Dongles can be used to protect valuable source codes, sensitive text information, and data files.
