Research and practice of digital fingerprinting encryption algorithm based on QR code

The common digital fingerprinting encryption algorithm has problems such as the code character is too long and the calculation is complicated, etc. Besides, the fingerprints generated are mostly meaningless binary sequence with bad intuition and no practical value. In this paper, a new type of digital fingerprinting encryption algorithm based on QR code is put forward, and experiments prove that this algorithm has sound resistivity to conspiracy attack and could trace the conspiracy user effectively.
