how to hide sensitive Information on Ticket History

[Servicenow_12]

There could be times where some sensitive data could be inadvertently added to an issue in a text format, on a comment, description, or other forms (Fields, etc). For security reasons and due to this information needs to be removed/ Hidden.
Although the user can remove the text, the information will still be present on the history tab of the issue.
Since the history tab can't be disabled, Kindly help me with a way  to remove data from the history to hide the sensitive information
