Kontaktkinnitust

Kontaktkinnitust is a term used in Estonian to describe the process of confirming and validating a contact method, such as an email address or phone number, and obtaining the user’s consent to be contacted through that channel. The goal is to ensure that communications reach the intended recipient, to improve data quality, and to support regulatory compliance and fraud prevention.

Common forms include explicit verification, where the user must perform a task (click a link, enter a code) to prove ownership, and implicit verification, where a successful transmission is considered confirmation. Typical workflow involves data collection, selection of a verification method, sending a verification message, user action to prove ownership, updating the verification status, and ongoing use with periodic re-verification when data changes. Verification records are often retained to demonstrate consent and data accuracy.

Methods and technologies used for kontaktkinnitust include email verification with a confirmation link or code, SMS or voice verification with a one-time code, and push notifications or in-app confirmations. In sensitive contexts, a multi-factor approach may combine several channels. Codes are usually time-limited and tied to a specific device or session. Practices emphasize data minimization, secure transmission, and auditable logs to support accountability.

Security and privacy considerations address risks such as phishing, SIM swapping, social engineering, and stale or incorrect data. Mitigations include rate limiting, anti-phishing measures, strict verification workflows, device binding, robust authentication, and clear opt-out options. Regulatory context varies by jurisdiction but commonly involves data protection and communications laws (for example, GDPR and ePrivacy in the EU) requiring consent records and the ability to withdraw consent. Applications include banking, e-commerce, telecommunications, and government services, where reliable contact data is essential for communications and security.
