ABSTRACT:
The invention includes systems and methods for maintaining control of an electronic record, which may have transferable value, wherein a user may add digital signature information to a single unique authoritative copy of the electronic record held in a repository without compromising the uniqueness of the authoritative electronic record. Provided the digital signature information is valid, an authoritative electronic record may be amended to include multiple digital signatures, while continuing to be a single unique authoritative electronic record.
