The article proposes a unified principle of permutation decoding (PD), which applies to redundant systematic block codes. This method allows using correction capabilities of such codes, but in the classical interpretation, the method requires cumbersome matrix calculations, which does not allow using the positive properties of the error correction method. The computing process is excessively complex. Therefore, to reduce the negative effect in the PD system, it is proposed to use the cognitive principle of data processing at the channel level, which significantly reduces the decoder complexity and ensures PD application in the air passenger biometric data systems.
