- How so? Database design always has to deal with security issues. Signature
- digitization doesn't change that. Before UPS had the signature, all they
- had, most likely, was a flag field called "signed/received" or something
- similar. How is that any more difficult to tamper with? There will always
- be the possibility of dishonest operators. The system design has to
- anticipate this, and combat the possible damage with audit trails, passwords,
- authorization levels, etc. Maybe even digitized signatures? :-)
