DigSig Decoding and verification SDK

Several countries worldwide are now utilising the power of ISO/IEC 20248 DigSig to protect their high integrity documents. DigSigs are being used to safeguard number plates, Wind Shield Labels (WSL) for motor vehicles, Head Lamp Tags (HLT) for motorcycles, and many other electronic vehicle identification industry solutions.

TrueVolve Technologies has been intimately involved in designing, developing, and implementing these technologies in several countries. We are making a set of Software Development Kits (SDKs) available which will enable developers in these countries to reap the benefits of this technology.

The IDOffline SDK is an ISO/IEC 20248 DigSig decoding and verification library which will enable third-party OEM developers to decode and verify DigSigs completely offline. This can potentially be very useful in the security industry in access control, e-tolling, and gate automation.
