Signing using GrIDsure authentication & authorisation

This demo uses unique signing keys held on the trusted server to sign PDF documents. The user is authenticated using GrIDsure grid. Later the user can authorise a document by responding to another challenge grid.
 
 
Step 1: Registered (Required once only)
New users: Fill in a simple registration form which will generate your signing keys on the server: 
 
Step 2: Login
Registered users:   Challenge Grid:
Your ID:
Your PIP:
  Enter the numbers from the challenge grid which match your chosen pattern.
   
Enter some sample data into the fields below.  This data will be placed into a final agreement PDF. You will be asked to sign using a digital certificate created for you during the registration process. The PDF document will be pre-signed by Ascertia so that a dual-signed agreement can be created and saved.

Notes
The advantage of this solution is that any type of web form can be signed by first converting it to a PDF form, and then signing it using locally-held keys (smartcard/token or soft signing keys).
The web form can be in any language.
In this demo we also apply a company signature before asking the user to apply a counter signature. The order of signing is fully configurable.
Signature’s can be applied within specific blank signature fields or stamped anywhere on the document, depending on business need.
The signature appearance is fully configurable and can also support multiple languages.
Strong user authentication is provided using GrIDsure grids, which changes every time ensuring the user’s security credentials cannot be captured and replayed.
