Voice Signature, Real Digital Signing

One of the biggest problems on the internet is trying to determine whether one is dealing with a real person or their dog, child or someone else. Current technologies tend to tie a transaction or interaction to a single device/workstation/smartphone, but do not actually connect a real person. This is because the device can be hijacked by other people. The obvious solution is a biometric identifier that ties to a person's unique attributes. Most biometrics aren't particularly well suited for the internet: iris and thumbprint scans require special equipment and aren't particularly hard to replicate. By contrast a voice signature system, when appropriately deployed, is very hard to replicate and can be deployed from any telephone or workstation. Here is a simple demonstration of how one would give their voice signature. Simply type your telephone number and email into the fields, the system will call you and capture your voice signature. This signature can be easily attached to any document and once captured can be used to authenticate that the person you are dealing with online is in fact the right person.

Cool technology, now in implementation.
