Summary

After a decade of deployment experience, the time has come to re-evaluate some core assumptions about how and when to use electronic signatures. Relying on public-key infrastructure (PKI)-based technology has its risks and drawbacks, but those risks can be reduced and managed, and some of the drawbacks can be overcome by the judicious use of alternative technologies and specialist service providers. Two of the dominant technologies of recent years -- mobile devices and cloud-based services -- can be exploited to materially change the picture and should prompt organizations to check whether their current thinking about electronic signature is still valid.
