A data anonymization technique for datasets including personal identifiable information (PII) such as utility datasets may primarily include assigning anonymous identifiers to nodes in the dataset and swapping or otherwise moving portions of information between nodes of the dataset. The methodology of the swapping or moving operation may vary optionally based on a number of parameters, and may include swapping endpoints under a single parent, swapping endpoints between similar parents, and / or swapping similar endpoints between parents. The anonymization technique may output an anonymized dataset which reflects a topology of the original dataset and may optionally be updatable and modifiable to include additional data about existing or new nodes.

Identity nodes within bidirectional dual node hashchain (BDNH) bundles generate hash keys by processing partial metadata and linking them through identity graphs. Translation nodes perform identity resolution, data anonymization, and re-keying by transforming original identifiers into anonymous IDs and re-key IDs. Laplace noise enabler capsules introduce Laplace noise into translation layer logs for differential privacy. BDNHs share metadata between adjacent bundles for secure and efficient data transmission. A cognitive analytics layer shared among all bundles verifies hashed encrypted data packets using a gossip protocol for real-time validation. An analytics workspace layer activates re-key IDs and creates digital tags for datasets using BERT transformers, linking data through knowledge graphs. The system manages parallel processing and includes machine learning modules, homomorphic encryption, federated learning, zero-knowledge proofs, attribute-based encryption, and anomaly detection. Bundles' AI engines work with the Laplace noise enablers to analyze data, optimize noise, and enhance the data clean room functionality.
