Is biometric signature safe?

Standards are the way to create secure solutions in the IT sector. Techsign's biometric signature follows these standards:
- ISO/IEC 19794
- PAdES (PDF Advanced Electronic Signature ETSI TS 102 778 and EN 319 142-1&2)

How can I be sure that my signature will not be transferred to another document?

Biometric data and document summaries are kept encrypted in the shared documents. Since the data is encrypted, malicious users can not open or steal the data. When they use the encrypted biometric data the document summary will not match, and the forgery will be easily detected.

Can I use biometric signature in different countries?

PAdES standard is valid on Europe. Techsign's biometric signature solution has this standard, so it can be used in Europe securely.

Which devices can I use?

You can use the biometric signature solution on all devices with touchscreens. Smartphones, tablets, and pc with touchscreen. The biometric signature needs the factors such as pressure, speed, and angle. So it can not be created by a mouse.

Can I see the signed documents with all pdf readers?

Techsign biometric signature follows the  ISO PDF standards. You don't need any other technology to see the signed documents. All pdf readers will work smoothly.
