Transform Your Smartphone Into a Signature Pad

Typical Use Cases

  • To capture signatures on smartphones or tablets in-store, in a branch, or in the office
  • For field agents to get documents signed in person

Forensically Identifiable Signatures on Smartphones

  • A signature captured with SIGNificant is much more than just an electronic image of a digitized signature. We record - the handwritten signature of a person using all available parameters, such as acceleration, speed, and rhythm. This makes the digitized signature forensically identifiable.
  • If there is a dispute about a captured signature, we offer an expert tool that forensically analyzes the biometric characteristics of the captured signature.
  • To make the signature forensically identifiable it has to be captured using a native pen or a stylus. Signing with the finger does typically not lead to forensically identifiable signatures.
  • We also provide a signature verification that authenticates a signature against a pre-enrolled signature profile database in real-time.

How it Works

  • You can review documents or complete form fields and add attachments on any computer and use your smartphone as a signature-capturing device
  • When you are ready to sign a document a secure communication between the smartphone and the host computer is established
  • A native app turns a smartphone into a signature-capturing device
  • Supports Android, iOS and Windows
  • Bank-grade Security

    • The biometrical signature data is encrypted asymmetrically using a public key directly while the signature is being record.
    • The signature is always securely bound to a unique document.
    • To prevent sniffing of the captured biometric data encrypt the communication between the smartphone and the server.
    • We show the relevant part of the document as the background image on smartphones to provide a visual link between the signature and the document for the signer.

    No Vendor Lock-In

    • SIGNificant is device-independent it can be used with a broad range of signature capturing devices from various manufacturers.
    • Some processes require basic signature pads, while others require more advanced devices.
    • SIGNificant addresses this issue with a modular architecture that enables the introduction of new devices by developing small device drivers that do not change the core solution itself. 
    • This solution ensures easy support and upgrades - even the complete exchange of devices with other vendors.
    • Biometric signatures can be exported according to the ISO/IEC 19794-7:2007 standard for biometric signature exchange, providing full vendor independence of the signed documents.
