eSign with Click2Sign

July 4th, 2010

Signing documents does not take place just in Retail locations anymore; the online channel is used more and more to sell of products and services. (E.g. handset upgrades membership application, etc.).

Click2Sign requires to identify the signatory, and to keep track of the signing process in an audit trail. SIGNificant Click2Sign is taking care of these challenges by various ways of identifying the signatory, as well as keeping the audit trail with the signed document, which makes these documents legally binding. Click2Sign offers various ways to identify a signatory. From a simple „I agree“ checkbox to a sophisticated challenge/response protocol using different channels.

PIN by SMS
The most sophisticated identification method is the PIN by SMS functionality. The user signs on the web using a PIN code. This PIN is sent to a cell number the user has to specify. Logging all the steps („SMS was sent to at with PIN code “ and „PIN was entered at from “) into an embedded audit trail, it can be assured, that the signatory is the holder of this particular cell phone. This is e.g. used today by wireless providers, who know their customer’s cell number.

PIN by E-Mail
The PIN by E-Mail method works the same way as PIN by SMS; the PIN is delivered to an E-Mail account instead. Useful if e-mail addresses are known upfront. A blacklist for e-mail domains is configurable, so known SPAM e-mail domains can be avoided.

Sign by Name
The User signs by entering his Name instead of a PIN. Optionally the name can be provided to the system by a backed system, and be compared when signing. The audit trail will show „User entered at from “

Sign by Click
The User signs by clicking an „I agree“ checkbox.The audit trail will show „User clicked I ‚agree’ at from “

External audit trail
The system can take external audit trail data. For example a calling application could first authenticate users by having them enter their credit card information, and provide the response from the clearing house to Click2Sign.
