The signature is captured as precisely as possible via your smartphone, inseparably linked with the document and transferred to the signature software eSignatureSuite, which then links your typeface and highly encrypted biometric data with the document.

The biometric signature data is securely encrypted in the smartphone and linked to the document in such a way that it cannot be misused with another document. A public RSA key (4096 bit) ensures that the biometric data cannot be decrypted without accessing the relevant private RSA key.  However, this is stored with a notary, who has also generated the key pair. In case of doubt, only this process enables the operator to prove that he himself was unable to decrypt the biometric data and misuse it in different or changed documents.

In addition, every signature is provided with a digital signature by the software so that each recipient can check the integrity of the document e.g. with the aid of Adobe Reader.
