Unique document Protection
Fast. Simple. Secure.
Whether it's the forgery of identities, travel documents or vaccination certificates: Document fraud is on the rise. Visible Digital Seals (VDS) protect your paper-based or digital documents and make them impossible for criminals to misuse.
A Visible Digital Seal (VDS) is a cryptographically signed data structure encoded in a two-dimensional barcode, usually a QR code. The code contains the essential information of the respective document as well as a digital signature that protects against data manipulation.
Visible Digital Seals (VDS) serve the purpose of ensuring the authenticity and integrity of documents in a cost-effective but secure manner using asymmetric cryptography.
Possible applications for VDS include travel documents, visitor badges, vaccination certificates or any other document whose authenticity and integrity need to be ensured.
Advantages
As complex and secure as the technology behind Visible Digital Seal is, the way it works is simple, fast and cost-effective.
Unlike elaborate security solutions such as rfid chips, you can print Visible Digital Seals on your document to be protected within seconds using a regular printer of your choice. The code can then be easily and conveniently verified with any conventional smartphone anywhere in the world.
Easy and cheap to produce
Save time and production effort. VDS could be printed with any regular b/w printer.
100% Secure
Due to the underlying ECDSA (Elliptic Curve Digital Signature Algorithm) signature it is impossible to falsify the data
Economical
Easily verifiable with any normal smartphone. No special hardware required.
USE CASES
Possible applications include travel documents, visitor badges or any other document whose authenticity and integrity need to be ensured. Typically, such a visible digital seal is created as a QR code or DataMatrix code.
Because the technology and structure is publicly described in so called "VDS profiles", it is possible that different parties (e.g. countries, organisations) will agree to mutually recognise and integrate these profiles into their existing processes.
Examples for VDS Profiles
● Arrival Attestation Document (Germany)
● Social Insurance Card
● Residence Permit Document
● ICAO Visa Document
● ICAO Emergency Travel
● ICAO VDS-NC (used in Australia's COVID-19 Vaccination Certificate)
If you have the need for your own purpose VDS profile, please don't hesitate to contact us.
Integrated Biometrics
A special feature of our VDS solution is the VisibleDigitalSeal BIO, which can contain biometric data of the user.
Thanks to our patented technology, this biometric information can be integrated into the security structure of the VDS. This innovation makes it impossible to alter or tamper the holder image on the document.
It can also be verified with a regular smartphone whether the person who wants to use the document is actually the rightful owner.
This function enables precise digital verification of individuals using a regular smartphone app and thus offers an additional layer of security.
Code Scan App
The Code Scan App (available for iOS & Android) from KURZ Digital Solutions can be used to read and verify visible digital seals in accordance with
- BSI TR-03137 specification
- ICAO TR "VDS for Non-Electronic Documents"
- ICAO Visible Digital Seals (“VDS-NC”) for Travel- Related Public Health Proofs
- and others
