(continued...) This enables a package of files to be created in much the same way as a Zip file, that can then be secured by password or biometrics like CADsign.
Similarly any tampering with the contents of the package instantly removes all signatures.
A version is also being developed specifically for Word.
Once a secure signature has been inserted a banner is placed across it instructing recipients to run the Wordsign verifier to ensure that no changes have occurred.
Document Flow offer a range of finger print scanning devices.
The Biolink mouse is a is a standard two-button computer mouse with a small fingerprint scanning device embedded while the Siemens ID Mouse combines an ergonomic scroll wheel with their capacitive as opposed to optical FingerTIP Sensor.
For users who do not want to change their input device, the Cherry keyboard offers an integrated fingerprint sensor and smartcard reader.
This allows users biometric data to be stored locally on the smartcard rather than in a database.
Most importantly, the fingerprint is never captured.
Instead, the BioLink technology creates a 500 byte mathematical algorithm of reference points that cannot be replicated into a user fingerprint.
In my limited trial period this worked rapidly and reliably.
The Document Flow Securesuite products address issues familiar to most users of electronic documents.
Full integration of CADsign within AutoCAD addresses the shortcomings of most current work rounds involving combinations of electronic and hard copy versions.
The extension of the range to Filesign and Wordsign provides a possible solution for users of other CAD systems and the prospect of package specific solutions in future.
The Enrolment package costs £840 including the Wacom digitiser for initial signature capture and can be used as the basis for all of the secure products.
The CADsign authenticator costs £195 with bulk discounts available and the verifier being free.
For biometric security the mouse costs £95 and the keyboard £155 with an additional digitiser at £70.
All in this represents a modest cost compared to the time that can be spent plotting, resigning, collating and posting traditional hard copies.
A fully functional non-biometric password version of CADsign is available from www.documentflow.co.uk complete with three example signatures.
