Lattice-based access control

Lattice-based access control is a way of controlling who can see or use certain things, like documents or websites. It works by setting up a "lattice" of different levels or types of permission. For example, you might have three or four levels - like an adult (level 3), a teenager (level 2) and a child (level 1). The level of permission someone has depends on how old they are. A child might only be able to access websites labelled as level 1, while an adult might be able to access everything. This lattice lets people control who can see what, making sure they can trust that the right people are getting the right information.
