(a) Even altering a parameter once in the address could be considered illegal under the current laws.
(b) The access of information in and of itself would not be illegal alone. Say I kept a bunch of people's information in paper files in file cabinets. Then I gave you access to retrieve yours from the file drawer yourself. It is sleazy, but not necessarily illegal to look at other files in the drawer, as I have given you access to their container.
(c) Even if you want to make the action in (b) illegal, the reasonable punishment is almost certainly not a double digit prison sentence.
