We add steganographic hidden marks on the whole document, we work with documents that include sensitive info, charts, and diagrams, not photos :) We don't add any patterns or symbols, just invisible changes that can be detected only by our tool. Our technology is patented. We will be happy if you can try our solution and share your feedback. We have a free tariff plan with access to full functionality via app.leaksid.com. Good luck!
