Capture biometric data such as pressure and timing

STU SDK - Windows and Linux

Using our low-level STU SDK you can capture pen data directly from the signature pad.
For all our pads this includes x and y co-ordinates plus pressure and timing information.
With our latest pads there is also a sequence number and a date/time stamp.

Signature SDK - Windows, iOS and Android

Using our Signature SDK you can encode the biometric data of the captured signature within the signature image - we provide samples illustrating how to do this on Github
The Enterprise (paid) version of the Signature SDK allows the export of the biometric information in one of the following two standard ISO formats:

• ISO 19785 - XML
• ISO 19794-7 - binary data

For details of costs for the Enterprise version please contact your regional Wacom Business Development Manager.  If you don't know who this is please use the "Submit a request" link at the top of this page.,
If you are using the "Lite" version of the SDK the only way to access the biometric data is to transfer the signature into one of our analysis tools (see below) for examination.

 Signature SDK for JavaScript

The JavaScript Signature SDK is charged on a transaction basis and includes within the fee the ability to use the ISO import and export functionality mentioned above.

DTU Tablets

If you are using DTU tablets to capture signatures you can access the biometric data using the Signature SDK as explained above, subject to the limitations described.
Alternatively you can use the Wintab API (supplied with the tablet driver) to access the pen data in real time, i.e. as it is being generated by the tablet..

iOS Devices

Using our Signature SDK for iOS you can encode biometric data captured with one of our Bluetooth Styluses within the signature image - we provide both objective C and Swift examples of how to achieve this.

ANALYSIS TOOLS

GSV (General Signature Verification) SDK

This tool allows you build up a template of six signatures or more against which future signatures are to be compared. A new candidate signature is compared against the six existing ones and a score is given indicating its compatibility.

Signatures can be captured dynamically from a pad or imported from an existing file; FSS files can be dragged and dropped onto the sample app.
For more information please see Github  

SignatureScope

This comprehensive analysis tool allows you to examine in detail the biometric data of a signature which has been captured using either sign pro PDF or one of our Signature SDKs.
Two versions are available - the demo version is available on request and enables a signature to be analysed which is captured directly from the user; it does not allow signatures to be opened from other sources such as a file or the clipboard.

The full (FDE) version of SignatureScope allows the user to analyse in detail a signature from any of the following sources:

1. Dynamic input by the user
2. A file created by our Signature SDK
3. Copy/pasting from sign pro PDF or the Signature SDK.

Please note that this full version is only issued to qualified Forensic Document Examiners (FDEs) after signing of a non-disclosure agreement.

MiniScope

MiniScope provides summary information about the biometric data contained within a signature.
