Well, seems like it’s time to build an enterprise-grade steganography FLOSS, don’t you think 
?
As for my use case, I need to send media files that are sensitive in nature to multiple trusted entities, but there’s always a chance of them being leaked, either by cyberattacks, disgruntled employees, or bribery. I want a way to digital watermark those files so that we can trace the source of leakage. Ideally the digital watermarking can be applied to any kind of digital files or data, but I just don’t think it’s even theoretically sound.
