The secrecy of the covert feature is not endangered, because two encryption keys are used: One key embedded in the new Cryptoglyph quality control system enables decoding of the public part of the covert feature used for quality control; the other key is kept secret on the Krypsos secured server and remains only known to the branded product manufacturer using a Cryptoglyph license.
