langchain_experimental.data_anonymizer.presidio.PresidioAnonymizer¶

class langchain_experimental.data_anonymizer.presidio.PresidioAnonymizer(analyzed_fields: Optional[List[str]] = None, operators: Optional[Dict[str, OperatorConfig]] = None, languages_config: Dict = {'models': [{'lang_code': 'en', 'model_name': 'en_core_web_lg'}], 'nlp_engine_name': 'spacy'}, add_default_faker_operators: bool = True, faker_seed: Optional[int] = None)[source]¶
Parameters

  • analyzed_fields – List of fields to detect and then anonymize. Defaults to all entities supported by Microsoft Presidio.

  • operators – Operators to use for anonymization. Operators allow for custom anonymization of detected PII. Learn more: https://microsoft.github.io/presidio/tutorial/10_simple_anonymization/

  • languages_config – Configuration for the NLP engine. First language in the list will be used as the main language in self.anonymize(…) when no language is specified. Learn more: https://microsoft.github.io/presidio/analyzer/customizing_nlp_models/

  • faker_seed – Seed used to initialize faker. Defaults to None, in which case faker will be seeded randomly and provide random values.
