Watermarked Security Service CD-R (name + barcode).
All these CD-Rs are individually marked. A glitch somewhere in the music is intentional and is a watermark. Those “glitches” are sofisticated made. With software like Soundforge or Cool Edit Pro you can open up the wav and zoom in on the glitch. You will see a series of small anomalies, like more than one glitch, really close to each other (so they sound like just one). These patterns are the watermarks – each disc has a unique set. The CD-Rs were sent out to journalist, and the like, and had their name printed on the CD (on the left), and under the bar code a number (the number to match the Barcode number). The top of CD-R is glossy.
