There is a real problem that people aren’t yet opting-in, in large enough numbers, to donate their organs after (brain)death.
Today’s invention is a web-based mechanism which makes it easy for a person to assert online that they’d like to donate in this way.
The website would also make it a very easy requirement for the recipient to change their name to include that of the donor. So Joe Smith who lives on after a donation by John Doe would be immediately and officially converted, in all official documentation and correspondence, to Joe [John, Doe] Smith.
In this way, a donor and his/her family could feel that their memory lived on and was fully appreciated by the recipient.
