Anonymization of documents

Athento allows documents to be anonymized, thereby hiding sensitive information from users.

The anonymization process consists of two steps:

1. Detection of sensitive entities in the document.
2. Anonymization of the document based on the sensitive entities extracted.
3. Display of the anonymized document.

Detecting sensitive entities in the document

To detect sensitive entities in a document, run the “op_anonymize_pdf_entities” automation, which is available in the list of automations in the space. This automation will only work correctly on PDF documents. It has two parameters:

• Black words: Entities that should be ignored in the detection. The operation may sometimes detect entities that should not be anonymized, so it is best to test it on a set of documents and include entities that we want to be ignored in this parameter. They must be separated by commas.
• Extract text: Check to extract text from PDF documents that do not have digitized text.

Once we run the operation on any PDF document, we will be able to see a feature with those sensitive entities and on which page and position those entities are located.

This value can only be seen by users who have administrative permissions for the document.

Anonymization of the document based on the sensitive entities extracted

Once we have extracted the sensitive entities from the document, an automation must be executed so that these entities are anonymized within the document.

This automation is “op_anonymize_document” When the process is executed, the entities classified as sensitive in the previous step will be hidden by black boxes, resulting in a new document with these concealment marks.
