HOW TO Redact….Your.. Personal

Stop blurring and pixelating your info

Blurring or pixelating your personal information is normally good enough to hide it from human eyes, but not from advanced software. All you’re doing is rearranging the data, not actually removing anything. Studies have shown that AI tools can be trained to decipher details that have been obscured in this way (see www.snipca.com/47108 for proof). Cybercriminals will be delighted that they have another weapon with which to scam victims.

Another technique to avoid is scribbling over text using digital marker pens. These tools simulate actual markers or highlighters, so the ‘ink’ is applied with less than complete opacity. Anyone seeing this image could download it, drag it into an image editor, and use brightness/contrast controls to see the text pixels underneath.
