For existing business applications, the mandatory
hardware confirming was not considered in their design and
development. If it is needed now, the MHCC filter module
will be used to intercept the application’s accessing some
data or performing critical operations, and determine whether
the hardware confirming is needed. If it does, the MHCC
user module will display the confirmation request interface.
The operation of application will be released if a normal
hardware signal appears in a certain period of time,
otherwise be refused.
