ANONYMIZATION OF DATA USING BLOCKCHAIN TECHNOLOGY: A MODEL FOR DATA LIFECYCLE MANAGEMENT TO ENSURE TRANSPARENCY AND COMPLIANCE WITH GDPR

The rapid growth in the volume of personal data collected and processed by various organizations poses significant challenges for ensuring information privacy and security. The General Data Protection Regulation (GDPR) of the European Union sets strict requirements for the processing, storage, and deletion of personal data, including the right to be forgotten, which entails the complete and irreversible deletion of information upon user request. This creates problems for traditional data management systems that cannot provide automated deletion and reliable compliance monitoring.This article proposes a new model for data anonymization based on blockchain technologies that combines smart contracts to automate data operations while using cryptographic methods to create a system resilient to de-anonymization. The model ensures control and compliance with regulatory requirements while maintaining transparency and security for all transactions. Keywords: blockchain, data anonymization, data management, offchain, right to be forgotten, smart contracts.
