kasutustugi

Kasutustugi is a digital signature format developed in Estonia, which has been in use since the 2000s. It was initially created to facilitate secure online identification for Estonian citizens. The format allows individuals to create and use their own digital signatures, which are equivalent to a physical handwritten signature.

This signature can then be used on various online documents, contracts, and transactions. The digital signature is tamper-proof and cannot be forged or altered.

It allows citizens to access online public services, such as taxes, bills, and employment information, securely and conveniently. Additionally, Kasutustugi signature can be used to authenticate online transactions and sign electronic contracts.

These efforts have enabled Estonia to become one of the most digitally advanced countries in the world. Today, Kasutustugi signature has been recognized as an example of innovative digital government solutions, demonstrating the potential benefits of secure online identification and digital signature technology.
