HIGH RATE ROBUST CODE WITH LOW IMPLEMENTATION COMPLEXITY

Computer Science and Engineering

The quick response Fault Injection Attack Elimination(QRFIE) code was designed for storage information and high-speed reading applications. In this paper, we present a new Read Solomon and four dimensional diffie Hellman algorithm. If a third party listened to the exchange, it would be computationally difficult for them to determine the secret colours. In fact, when using large numbers rather than colours, this action is computationally expensive for modern supercomputers to do in a reasonable amount of time. That has two storage levels and can be used for document authentication. The private level is constructed by replacing the black modules by specific textured patterns. It consists of information encoded using q-ary code with an error correction capacity. This allows us not only to increase the storage capacity of the QRFIE code, but also to distinguish the original document from a copy. This authentication is due to the sensitivity of the used patterns to the print-and-scan (P&S) process. The pattern recognition method that we use to read the second-level information can be used both in a private message sharing and in an authentication scenario. It is based on maximizing the correlation values between P&S degraded patterns and reference patterns. The storage capacity can be significantly improved by increasing the code alphabet q or by increasing the textured pattern size. The experimental results show a perfect restoration of private information. It also highlights the possibility of using this new rich QRFIE code for document authentication.
