Computer-implemented method and system for checking data anonymization

The invention relates to a computer-implemented method and system for checking anonymization of data. The anonymized data (D2) is analyzed by an intelligent contract process based on data privacy rules (PR), thereby automatically generating flags in the event of anomalies. The intelligent contracts may be managed in a decentralized manner, where anodes of a distributed database (DB) may verify rules specified in the intelligent contracts and/or evaluate anomalies. To this end, test data (D3) is generated at the data source by applying a data privacy rule (PR) to the raw data (D1). The test data (D3) is checked against the anonymized data (D2), and metadata (MD) is generated on the basis of the check result. Metadata (MD) is provided to nodes of the distributed database for further verification. 本发明涉及用于检查数据的匿名化的计算机实现的方法和系统。匿名化数据(D2)通过基于数据隐私规则(PR)的智能合同过程来分析，从而在异常的情况下自动产生标志。智能合同可以以分散的方式管理，其中分布式数据库(DB)的阳极可以验证智能合同中指定的规则和/或评估异常情况。为此，通过将数据隐私规则(PR)应用于原始数据(D1)，在数据源处生成测试数据(D3)。对照匿名化数据(D2)检查测试数据(D3)，并根据检查结果生成元数据(MD)。元数据
