The method of the preferred embodiment can further include combining the first portion of the digital signature and the second portion of the digital signature; and delivering the digital signature to the first user device. The method of the preferred embodiment can function to secure the digital signature process by splitting or dividing the user's private key into two or more portions, each of which require independent authorization from the user in order to create the digital signature.
