Pretty damn generic patent.
The one little part I like is the part about deleting the data stored in
memory then retransmitting it. Or, I guess if you read it really
literally, the secure server cuts its own throat by clearing DRAM then
continues to operate properly. Even cutting them lots of slack you'd
probably want to verify that the information reached its destination
intact before cleaning house locally. Sounds like the sort of guys who
will free a buffer then continue to use it and be mystified for weeks by
their system's behavior.
The abstract is not the heart of a patent but they could have done
better. I'd fire Patnaude Videbeck & Marsh.
