New SignWise™ Module for ViewWise 5.6
The Digital / Electronic Signature Solution with Biometric verification
Chicago, IL, August 1, 2005 – “The ability to hand / digitally sign electronic documents and transactions, then be able to authenticate and audit the signatures at any given time is central to a state-of-the-art, enterprise-wide Document Management system,” said Joe Wharram, President of Computhink, “and Computhink, in partnership with Topaz Systems, Inc., makes this possible.”
The new SignWise module provides a complete digital signature software solution for the capture, encryption, storage, and verification of electronic signatures in all types of electronic documents. They are secured, validated, controlled, tracked and audited within ViewWise.
“Topaz is pleased to assist Computhink by providing the signature component of their SignWise document solution,” said Anthony Zank, President of Topaz Systems, Inc. “Coupled with the SignWise application, our electronic signature technology helps deliver the benefits of paperless transactions to a new set of users and business environments.”
Signatures can be added to any document, and once applied, should the document be subsequently edited and or modified in any way, then the document signatures are revoked, dissolved and an audit trail record triggered. On output from ViewWise the option to generate a Certified Document is provided. This certification generates a Global Unique Identifier (GUID) that is appended to each page, regardless of the file format. The GUID validates the pages of the document to the signatures shown on the certification page. At any time signatures and GUID can be validated within the issuing system.
There are two signature options dependant on the level of authenticity required, both fully tracked and audited by ViewWise:- Certified Signatures – (Electronic) utilizing a Topaz (SignWise) signature pad, signatures are first registered in AdminWise and a biometric template is compiled. Then when a subsequent signature is to be applied to a Document, via a signature pad available on a ViewWise client, a verification of user ID and password is required followed by a biometric validation of the actual signature in real time. When authenticity is confirmed only then is the signature applied together with a text confirmation of the User and a date/time stamp. When applied the process binds the signature to the document using secure Hash and Encryption. Provided a signature pad is utilized, a registered Certified signature can be applied from any ViewWise station on the network that has a SignWise signature pad available.
- Authorized Signatures – (Digital) again, utilizing a SignWise signature pad, signatures are first registered in AdminWise against registered users. When the registered user, on any given document, requests a signature, then subject to verification of User name and password and confirmation that a valid Authorized signature is available for that user on the system, an Authorized signature is automatically applied together with a text confirmation of the User and a date/time stamp (no signature pad required). When applied the process binds the signature to the document using secure Hash and Encryption.
Visual Representation
ViewWise Documents that have Certified and/or Authorized signatures are clearly marked with icon representations at the document level. Access to view all applicable signatures is available and if subsequently those signatures are revoked, this action is clearly designated. At any time the list of both active and revoked signatures for any document can be viewed.Verification and Validation of Document Signatures
On document output from the system i.e. print, fax and or email, the Certified Document option details the identification of the document, number of pages, index information together with a full listing and display of all active signatures in a cover page together with the GUID which is appended to each page regardless of the file format to validate the pages of the document to the signatures listed.
Signature/Document Security and Authentication
SignWise makes use of Topaz’s powerful SigPlus tools and methods for signature and document security. The signature is saved as raw, unaltered data encrypted to the document itself. If the document’s contents change, the signature is invalidated and revoked. Later, this raw pen data can be examined by forensic experts with SigAnalyze, a tool that Topaz provides free of charge to licensed document examiners to support the authentication of electronic signatures.About Computhink
