Wacom Ink SDK for verification
Signatures you can trust
Real-time fraud prevention
Banking staff need to be confident that a signatory is authorized to confirm important decisions like large cash withdrawals. But this can be tricky when the employee and the customer don’t know each other by sight. So, how do you catch an imposter trying to forge a handwritten eSignature?
You integrate a signature verification engine into your document management system: one that can confirm the authenticity of handwritten eSignatures at the point of signing, in real time. Wacom Ink SDK for verification is the most accurate and reliable solution available.
Image-based signature checks
Some decisions, such as voting by post in an election, are authorized with a paper and ink signature without any in-person interaction, making signature authentication more difficult. The comparison engine within Wacom Ink SDK for verification also enables the accurate authentication of signatures after they have been created, by comparing them with known genuine examples.
Protecting process integrity
Handwritten signatures are often crucial for organizational workflows, e.g., within hospitals. People in positions of authority need to know their authorization maintains its power after they have signed a document. And employees involved in authentication processes need to be confident that signatures provided by decision-makers are genuine, especially when they don’t know each other by sight.
Wacom Ink SDK for verification provides this confidence in real-time, wherever handwritten eSignatures on digital documents are integrated into important decision-making processes.
Ensuring restricted access
Modern digital verification techniques such as fingerprints and retinal scans used for system or building entry can actually be insecure because they rely on static images, which can be faked. Handwritten eSignatures, authenticated in real time by Wacom Ink SDK for verification, provide a dynamic alternative that is harder for imposters to beat.
What it is
Wacom Ink SDK for verification is a set of software tools that enable organizations to verify the authenticity of signatures accurately and with less effort than humans can achieve on their own.
The SDK contains a verification engine that enables two types of integration: dynamic (real-time) and static (image-based). It is the only solution on the market that enables both these types of signature verification within a single product. They can be used either independently or in combination.
How it works
After a lightweight integration with an organization’s document management system, the SDK’s verification engine can be used to compare new handwritten eSignatures (in real time or based on signature images) with up to 6 reference examples stored by the organization. The engine then generates a simple, highly accurate and instant accept/reject score on each signature between 0 and 1, where 0 represents no similarity and 1 represents an exact match. The workflow owner can decide the score that must be achieved to justify acceptance. In addition, the engine is built in favor of a low false acceptance rate to ensure maximum security.Importantly, the software does not store any of the signature data it captures, eliminating the potential compliance problems that affect alternative server-based solutions.
Real-time signature verification
Real-time verification accurately validates the biometric data and visual characteristics of a handwritten eSignature as it is created. It does this by comparing it with up to 6 reference signatures collected over time and stored on the company’s servers. These biometric data include specific aspects of the signature’s shape but also, for example, the speed and pressure applied in creating it.
Image-based signature verification
Image-based verification compares a static image of a signature against up to 6 known reference signatures by comparing the proportion of linked visual features in the signature, and their similarity.
The SDK supports a wide range of image types (png, bmp, tif, jpeg, etc.) and provides options to:
- Clean image speckle
- Adjust contrast and brightness
- Remove fold lines
- Normalize signature sizes
