I have the following case scenario: One document that needs to be sign digitaly (using an external signing service) by 4 different people. The 4 people must be present while signing the document at the same place.
How can I create a situation where "digitally speaking" is ensure that the 4 people were signing while being together?
I thought that if each one of them uses the same computer (each of them logging in the signing service) that would be a way since it is the same datamachine (same IP). Is there any others?
Thanks a lot !!
