問題文

A release board reviews two picks for a banking client. The first pick decides which construction the scheme that hides stored text is built on, given that the scheme must also make any later alteration of that text visible. The second pick decides which second factor the sign-in flow asks for, given that a proof gathered by a look-alike site must be of no use anywhere else. Which option names both picks?
