Capability machines and tagged architectures have an interesting history. The first I know of is the Burroughs 6600 from the mid to late '60s: https://en.wikipedia.org/wiki/... Then there's the Intel 432 https://en.wikipedia.org/wiki/... and the short-lived BiiN system that was a successor to the 432: https://en.wikipedia.org/wiki/... But a lot of this dates back (like so much of computing) to Multics and its mandatory access control mechanisms.
