Eutron Smartkey Software Protect

SmartKey from Eutron is a compact sized hardware key to be plugged into the PC parallel port or USB port (depending on the model). Every Smartkey electronically holds its own unique identity number, which is recognized by the software to be protected and enables it to run properly.

During its execution, the software first verifies the key's presence and its internal code; when a correspondence is established, the software keeps on running, otherwise it is stopped. The software may be protected either by automatically encrypting executable files or integrating specific software drivers.

SmartKey is easy to install, secure and discreet: after plugging the key into the PC, the user can forget all about it, because its presence is fully transparent. But if the key is removed, the software stops running.

SmartKey limits the use of the software to one copy at a time, without preventing the execution of archive or back-up copies. Used by over 5,000 software houses the world over, SmartKey represents the state of the art in software protection being based on ASIC (Application-Specific Integrated Circuit) chips specifically designed for its security functions.
