käsivivun

Käsivivun refers to a method of data protection used in Finland, specifically in the context of the Public Sector Information Act. It is designed to provide a secure means of communication and data exchange between government agencies and private sector companies.

Under the Käsivivun system, data is encrypted and transmitted securely using a public key infrastructure (PKI). Only authorized parties with the corresponding private key can decrypt and access the data. This ensures confidentiality, integrity, and authenticity of the data exchanged.

The system is based on the use of digital certificates, which are issued by trusted certification authorities. These certificates contain the sender's and receiver's public keys, as well as a digital signature. When a user initiates a secure data transfer, the system checks the sender's and receiver's digital certificates to verify their identities.

Käsivivun is used extensively in Finland's public sector, particularly in the areas of healthcare, social security, and taxation. It ensures that sensitive data remains confidential and within the boundaries of authorized parties. While the system primarily focuses on secure data exchange, some of its features are also used for electronic signatures.

The Käsivivun system is designed to be compatible with various standards and regulations, such as the European Union's legislative and regulatory framework for the protection of personal data. It remains a vital component of Finland's data protection and cybersecurity landscape.
