Recover Redacted Information Based on Font

In recent times, there has been a growing concern about redacting sensitive information in digital images. One common method of doing this is using the markup tools in the Photos app of iOS devices. However, a recent article has highlighted some potential flaws in this approach.

The foolproof method of redacting information is to use the rectangle selection box, press delete, and fill (without deselecting) the same space black. This may seem like a simple solution, but it has its limitations. In fact, loading filling the space in with black doesn't redact anything more than what the deletion did.

For those who need to manipulate images further, importing them into GIMP and then exporting them in JPEG or PNG format can be a useful option. However, this method is not foolproof either, as it may still leave some information visible.

One common recommendation against using the pen tool for redaction is that it is semi-transparent. This means that small lines used to cover up text may not be opaque enough to completely conceal the original information.

A recent article recommends against using iOS markup tools for redaction due to their lack of opacity, even when using the opacity slider at its maximum setting. The article also notes that the pencil and marker tools in Markup are not designed for redaction purposes.

For those who have inadvertently shared redacted images containing sensitive information, recovering what is underneath the blacked-out parts can be a challenge. In some cases, it may be possible to recover the original information using image editing software or other techniques.

In conclusion, while there are various methods of redacting sensitive information in digital images, none of them are foolproof. It is essential to use caution when sharing images containing personal or confidential information and to take steps to ensure that the information is fully concealed.
