Is there a secure/robust/removal resilient watermarking technique ?
Yes and No. The use of these terms on an application specific case might be true but not universally. So, a better question is “Is this watermarking technique secure/robust for this application ?”. There is the same problem in cryptography: people think their system is secure because it uses RSA. This is an illusion: hackers focus their effort on protocols or on implementations but they never try to break RSA [Jeffrey A Bloom] Try the early Digimarc patents. Geoffrey Rhoads does an excellent job in the disclosures describing “knots” and “rings” and “tapestries”. That technique is robust to rotation, crop, and resize, it is a blind detection technique, it is an n-bit watermark, i.e. it has a payload rather than a 0-bit watermark which is simply present or absent, but carries 0-bits worth of information. I suspect that these patents are the foundation of the Mediabridge technology. That is clearly blind, multi-bit, and robust to the distortions you mention (as well as others).
