Improving QR Code Security using Multiple Encryption Layers
Samyukta Narayanan, S. Prabhu, E. Padma · 2024
Growing concerns about identity theft and privacy are brought on by the increased sharing of digital information, which leaves data open to quick changes while in transit. Digital data must be protected from hackers. This study presents a novel approach to improve QR code security and fight counterfeiting. This technique strengthens QR code anti-counterfeit measures by integrating the AES algorithm with Rubik's Cube Principle. The Rubik's Cubic Principle is used to separate the RGB channels in the QR code image. Following the encryption of these channels using the Advanced Encryption Standard (AES) encryption key, the encrypted image is combined with image steganography and is subjected to linear feedback shift register (LFSR) processing. Test results confirm the efficiency of the suggested plan, exhibiting strong encryption and flawless covert abilities.
