When using redaction software, be sure to remove metadata – hidden text/images/data. This will remove the risk of reidentification by hidden methods. Most redaction software has this functionality, so be sure to apply this before you start your redactions.
When marking a document for redaction, make sure your redaction boxes cover the desired text completely, this will minimise the risk of data being accidentally released. It’s best practice to have the redactions checked by a second expert or equivalent to ensure that the quality assurance process and the SAR policy is adhered to.
