Dongle secures software distribution

An economical security dongle comes preprogrammed with a unique, unalterable identification number readable from any USB port

The DLP-D is a new, very economical security dongle that comes preprogrammed with a unique, unalterable identification number readable from any USB port.

Software Guardian provides a simple way for developers to restrict software to a specific individual or PC, and contains a whole library of functions usable with any Windows-based software language using ActiveX controls.

A more sophisticated version Software Guardian Pro 2 provides additional easy-to-use capabilities, invaluable to software authors.

These include the ability to validate user identity without requiring any network or internet connection, attach software to a LAN, WAN, or corporate network, detect software tampering, enable/disable software features, meter software usage, enforce periodic software renewal, reactivate expired software licenses etc.
