Hypothetically, if you have memory problems and need to write down events, is there a system which you can verify that its not tampered with? (Like a digital checksum, but for a journal)
if you are able to remember the method to create the signatures then you can do many things e.g a simplified digital signature. but if you can't remember a method then you can't ensure that someone else has forged a signature, because if you forget everything then you have the same information as anyone else and anything you can do, they can also do
