VERIRICATION
What do you think what is verirication?
Our electronic definitions web site has answer for that as well:



verirication
is the act of checking transferred data usually at the stage of input to a
computer by comparing copies of the data before and after transfer (e.g.
repeating the keyboard operations to check that the data has been correctly
transferred in a keytodisk system or when punching paper tape). Where a
separate device performs this task it is called a verifier.
