"There are certainly many applications for simple e-signatures such as what some of our competitor's do, but there are many applications, markets and industries which will accept nothing less than the enhanced trust and security of a PKI-based digital signature. The legal requirement, or at least preference, for digital signatures in many countries would limit Adobe's acceptability in those markets if they turned away from their long commitment to digital signatures, and leading U.S. solutions which have dramatically reduced the complexity of PKI make it accessible here as well."
Pem's right. PKI-based digital signatures are well-respected across many countries' borders and to insure secure signatures, they're definitely needed. What are your thoughts?
