Abstract
A method for redacting an electronic document (ED) having a file format, including: obtaining a request to redact a sensitive data item in the ED; identifying a first instance and a second instance of the sensitive data item in a markup of the ED, where the second instance of the sensitive data item is not visible in a rendered version of the ED; and generating a redacted ED having the file format by: replacing the first instance of the sensitive data item and the second instance of the sensitive data item with a neutral data item, and inserting, into the markup, an encrypted version of the sensitive data item at a first location.

A method for redacting an electronic document (ED) having a file format, comprising:
- obtaining a request to redact a sensitive data item in the ED;
- identifying a first instance and a second instance of the sensitive data item in a markup of the ED,
- wherein the second instance of the sensitive data item is not visible in a rendered version of the ED;
- and
- generating a redacted ED having the file format by:
- replacing the first instance of the sensitive data item and the second instance of the sensitive data item with a neutral data item, and
- inserting, into the markup, an encrypted version of the sensitive data item at a first location.
A system for redacting an electronic document (ED) having a file format, comprising:
- a computer processor;
- a user interface (UI) configured to obtain a request to redact a sensitive data item in the ED;
- an identification engine (IE) configured to identify a first and a second instance of the sensitive data item in a markup of the ED,
- wherein the second instance of the sensitive data item is not visible in a rendered version of the ED;
- and
- a redaction engine (RE), executing on the computer processor, and configured to generate a redacted ED having the file format by:
- replacing the first instance of the sensitive data item and the second instance of the sensitive data item with a neutral data item, and
- inserting, into the markup, an encrypted version of the sensitive data item at a first location.
A non-transitory computer readable medium (CRM) storing instructions for redacting an electronic document (ED) having a file format, the instructions comprising functionality for:
- obtaining a request to redact a sensitive data item in the ED;
- identifying a first instance and a second instance of the sensitive data item in a markup of the ED,
- wherein the second instance of the sensitive data item is not visible in a rendered version of the ED;
- and
- generating a redacted ED having the file format by:
- replacing the first instance of the sensitive data item and the second instance of the sensitive data item with a neutral data item, and
- inserting, into the markup, an encrypted version of the sensitive data item at a first location.
