Digital Signatures
Trust mechanisms on Web are poor:
www.macdonalds.com Is it really?
www.usedcars.co.uk Can I trust them?
www.bath.ac.uk/courses/ Are these course details legally binding?
Digital Signature Initiative (DSig) aims to provide a trust architecture:
Signatures This page really is from x
Assertions This assertion is legally binding
DSig will be implemented in PICS
