Documents can be signed using electronic signatures. Key factor here is authentication of both parties, signing the document.
Companies, such as Adobe Sign, offer knowledge-based, social and phone verification of ID and lastly using digital certificate.
Knowledge-based authentication is only possible in US and therefore useless in international business. Having a digital certificate seems unlikely in the small business owners and is "killing" business. Therefore, social and phone verification seem to be the fastest and most business friendly option.
Does social and phone verification stand a chance at the court of law?
I can see many potential exploits. In the case of phone verification, signer of the document may buy a fake SIM card and try to prove that he/she didn't agree to the the terms of contract, because the phone number does not belong to him. In the case of social verification -> the signer of the document may create a fake social account. So does these two authentication offer any reliability? Can they successfully be used on the court?
To put things into practical terms. 2 parties who never met and do not know each other want to make a copyright licence agreement. Client sends the contract to the copyright owner, who signs it using social or phone authentication. Is such a contract of any value? What can be done if the copyright owner fakes its social or phone ID and later files a copyright lawsuit?
