3.Voice print and speech password: some specific person speak a specific pass instruction sentence
And a non-biological authentication like Time limited password to your mobile phone
Which and how many authentications should be taken depends on how important the document is!
Once the document was authenticated and signed by both sides it will be sealed and unable to edit by both side! Public documents could be accessible to any people like a administrative decree. And private documents could only be viewed when you input the password or biologically authenticated.
When both parties have arbitration or litigation, the court has the right to access public documents for inspection as court evidence. At this time, office public documents could charge the parties for its credibility!
