Title
(EN) SYSTEMS AND METHODS FOR USING NATURAL PSEUDONYMIZED TEXT
(FR) SYSTÈMES ET PROCÉDÉS D'UTILISATION DE TEXTE À PSEUDONYMISATION NATURELLE
Abstract
(EN)
The present disclosure directs to systems and methods for natural pseudonymization used in downstream processing. A natural pseudonym has at least one information attribute that is the same as a piece of sensitive text information. The systems and methods can identify sensitive text information, select a natural pseudonym, modify a data stream of text data by replacing the piece of sensitive text information with the natural pseudonym, and provide the data stream for downstream processing. Further, after downstream processing, some systems and methods can receive the downstream output and reidentify the downstream output.

La présente invention concerne des systèmes et des procédés de pseudonymisation naturelle utilisés dans le traitement aval. Un pseudonyme naturel a au moins un attribut d'informations qui est le même qu'une information textuelle sensible. Les systèmes et les procédés peuvent identifier des informations textuelles sensibles, sélectionner un pseudonyme naturel, modifier un flux de données constitué de données textuelles en remplaçant les informations textuelles sensibles par le pseudonyme naturel, et fournir le flux de données pour le traitement en aval. En outre, après le traitement en aval, certains systèmes et procédés peuvent recevoir la sortie en aval et réidentifier la sortie en aval.
