Please help me understand this paragraph under e-commerce law RA 8792 Sec.11
The person seeking to introduce an electronic data message and electronic document in any legal proceeding has the burden of proving its authenticity by evidence capable of supporting a finding that the electronic data message and electronic document is what the person claims it to be.
How can someone prove the authenticity of an electronic data, if anything and everything is possible in a computer. (This is why we have so called virus that can alter or delete any files in the computer)
Does it mean also that if someone disagree or argue that the electronic data is not authenticated, the person that disagree must also prove his argument?
Thanks in advance
