Overview

The creation of the electronic signature records the image of the signature and the biometric data in PDF/A format, and links it to the document through HASH algorithms (recommended by Germany´s Federal Office of Information Security) and asymmetric encryption, preventing manipulation and theft. The latest StepOver signature pads link and encrypt the data directly in the hardware of the device, and with the help of the Signature API and the free device API, it is possible to create basic and advanced applications for electronic signing. The Signatur-API is an OCX component that can be integrated into your application. Licences are issued per workplace.

An Signature API is highly suitable for the setup of a system for simple and advanced e-signatures.

Features

The signature in the document

In addition to the static signature image, which is visibly inserted into the document by the API signature, encrypted and compressed dynamic biometric data is embedded into the document. This includes vertical, horizontal and pressure components, as well as temporal evolution, including acceleration, that the device API outputs after encryption (4 dimensional data of the signature). This biometric data can be used in the event of a legal dispute at a later stage or confirmed in real time in an identity check is required. Verification based on a signature reproduced on paper is also possible.

Secure e-signing

The Signature API combines the security of the HASH algorithms recommended by the Federal Office of Information Security (Germany), such as SHA256, with a 2048 Bit RSA encryption, based on two asymmetric key pairs. The Signature API offers the highest level of security possible when combined with StepOver signature pads, as the encryption takes place in the hardware itself. Therefore, it is not possible to change a document after signing it without this being detected by a verification process. It is also impossible to insert the signature into another document, since the biometric data is embedded within the document and encoded with the document content using an asymmetric encryption algorithm (public key). The second key pair of the procedure allows you to identify the user digitally if desired.
