Correlating personal IDs to online digital IDs

A method, comprising the steps of:

• at a computer, obtaining records of multiple digital events from multiple vendors of digital event records, each digital event record having a digital ID of a user that initiated the respective digital event;
• at the computer, obtaining at least one list of professional registry numbers of professionals in a profession;
• by the computer, classifying at least some portion of the digital event records and at least some internet web pages based on a standard taxonomical index;
• and
• by the computer, identifying correlated identification data points among the digital event records and the professional registry records, and based on the taxonomic classification of pages and digital events, to infer a correlation between digital IDs from digital event records and actual physical identities of physical persons, and computing a parameter reflecting a degree of certainty of the inference.

A apparatus, comprising:

• one or more processors;
• a machine readable, nontransitory memory, having stored therein instructions programmed to cause the one or more processors to:
• obtain records of multiple digital events from multiple vendors of digital event records, each digital event record having a digital ID of a user that initiated the respective digital event;
• obtain at least one list of professional registry numbers of professionals in a profession;
• classify at least some portion of the digital event records and at least some internet web pages based on a standard taxonomical index;
• and
• identify correlated identification data points among the digital event records and the professional registry records, and based on the taxonomic classification of pages and digital events, to infer a correlation between digital IDs from digital event records and actual physical identities of physical persons, and computing a parameter reflecting a degree of certainty of the inference.
