Marked ghost imaging
I wonder if this can be applied to an all digital information scenario (no image or imaging sensor per se)? The usage of sending dummy data is workable, but is this a special type of keying/encryption setup or does this already exist in classical cryptography?

Microtags for anti-counterfeiting & brand protection from Trutag
Some sort of weird passive spectral tag, using spectral response spikes as a kind of passive barcode. Tiny and made of inert silica so edible.

GSITWiki: Storing Data In Video
Evil hack to make a youtube movie made of frames featuring QRcodes as a means of data storage. So that means you could upload a 10GB archive of data to youtube and get them to CDN the file worldwide. It also reminds me of stuff from GITS:SAC, where TV streams had QRcode like footers, and printed books with only QRcodes (no words or pictures), so the data can only be interpreted via AR glasses or brain implants...

Encoding many channels on the same frequency through radio vorticity: first experimental test
New trick of adding vortex twist rather than traditional polarization to a signal to boost encoding for a single frequency. The requirement for what appears to be a directional helicoidal parabolic antenna ( does this mean the antenna needs to be a few wavelengths in depth?) means no love for mobile omnidirectional antennas though.
