barcode watermark

See Digimarc.


A digital watermark from Digimarc Corporation that works like a QR barcode for both print and audio but much less "techy." Hidden to the naked eye in a common SCAN HERE icon as well as in everyday printed material, the code is also not discernible in the audio signal of a video or TV commercial. However, the Digimarc mobile app is able to recognize the code via print or sound and retrieve the appropriate Web page for more information. See digital watermark and barcode.

The two SCAN HERE icons from the Winter 2014 issue of CNET Magazine look alike. Under magnification, the dot patterns are visibly different however.
