Abstract

Problem Solved By This Invention: IBM has recently developed an integrated RFID (Radio Frequency Identification) interface for PCs and other intelligent electronic devices. This subsystem consists of a dual ported non-volatile memory element with both a digital serial (I2C) and Radio Frequency interface. The two major building blocks of the subsystem consist of the RF capable EEPROM and a cabled antenna through which it receives and transmits the RF signal.

Software License Authentication through the PCID Interface

   Problem Solved By This Invention:

   IBM has recently developed an integrated RFID (Radio
Frequency Identification) interface for PCs and other intelligent
electronic devices.  This subsystem consists of a dual ported
non-volatile memory element with both a digital serial (I2C) and
Radio Frequency interface.  The two major building blocks of the
subsystem consist of the RF capable EEPROM and a cabled antenna
through which it receives and transmits the RF signal.

   This invention describes a method for providing a
software license authentication mechanism by using the common
non-volatile memory in the PCID subsystem.  Current license control
mechanisms such as parallel port dongles are awkward to configure and
can be easily lost.  This invention provides a way through which the
source manufacturer installing the preloaded software can include the
license information in a secure area of the PCID EEPROM.  The
application can then verify that a valid license is present each time
it is loaded.  Since the PCID interface is accessible through both
the PC and through a wireless link a corporate user can initialize
their specific license information to the systems during deployment
without ever powering on the PC.

   Description of Invention:

   The PCID EEPROM merges a standard serial EEPROM bus
connectivity and package with a RFID tag function to produce a dual
ported non volatile management area.  The ...
