Automated removal of personally identifiable information

摘要

A natural language system may receive user-input. The user-input may include personal or restrictable information. The natural language system may provide a dual processing system. The natural language system may store a true copy of the user-input, which may include the personal or restrictable information. The natural language system may also generate an obfuscated copy of the user-input that does not contain personal or restricted information. The true copy of the user-input may be stored in a secure storage system and may be retrieved by authorized personnel, which may include the user who provided the user-input. The obfuscated copy of the user-input may be stored in a storage system and may be employed in ongoing training of the natural language system.

主权项

1. A method of processing natural language communications comprising:
receiving, via a natural language system, user-input that includes restricted information spoken by a user; identifying the restricted information in the user-input, the identifying comprising:
determining that one or more words of the user-input match one or more words of a restricted string;determining, at least partly in response to determining that the one or more words of the user-input match the one or more words of the restricted string, a context of the one or more words of the user-input; anddetermining that the one or more words of the user-input comprise the restricted information based at least in part on the context and based at least in part on the one or more words of the user-input matching the one or more words of the restricted string;generating obfuscated user-input by removing the restricted information from the user-input;storing the obfuscated user-input in a datastore; andtraining the natural language system with training data that includes the obfuscated user-input.
