METHOD OF THE INFORMATION PRIMARY PROCESSING WITH TRANSMISSION ERRORS DETECTION AND CORRECTION Russian patent published in 2018 - IPC H04L1/00 

FIELD: information technologies.

SUBSTANCE: invention relates to information processing systems having internal redundancy and distorted by the interferences. Technical result achievement basis is the messages code structures allocation <X_j^*>₂ = <X_j>₂ + <ε_j>₂, where <>₂ – data presentation symbol by the binary code with the known number of digits N, and <ε_j>₂ – errors caused by of binary code symbols inversions under the influence of interference, dividing them into components or code segments <<a_2j^*>₂,<a_1j^*>₂ >₂, where the superscript sign (*) indicates the possible presence of errors, which, with the reception or processing, are considered as the single N-bit binary positional code structure, selected components or code segments <a_2j^*>₂,<a_1j^*>₂ are rearranged in places with formation, as the structural-algorithmic transformations result, of new words or messages <C_j^*>₂=< <a_1j^*>₂,<a_2j^*>₂ >₂ = <C_j>₂ + <c_j>₂, differing, with respect to the minimum code distance initial number d_min⁽¹⁾, by the d_min⁽²⁾ minimum code distance new value d_min⁽²⁾= d_min⁽¹⁾ × 2ⁱ, increased by 2ⁱ times, where i is the number of digits of the lowest segment <a_1j^*>₂, after the encoding result <C_j^*>₂ division to the minimum code distance d_min⁽²⁾ new value producing the division remainder ξ_μ, which is used as the invariant, ξ_k (ξ_k≠ξ_μ) value is identified as the fact of error detecting caused by the interference, which is corrected by the different residual value ξ_k replacement with the ξ_μ value, which is the most repetitive in the extracted data graphic fragment, enclosed between the additional coding results neighboring values, for which the inequality is fulfilled |C_j^* – C_j+1^*| > (0.8 – 1) m₂, where m₂ – selected second comparison unit, equal to 2^N, and N is number of the binary code bits used to represent the words or messages meanings.

EFFECT: technical result is the ability to detect and correct errors in information transmission due to its internal redundancy associated with the presence of correlation dependency between the digital information neighboring values; provision of additional control over the received and restored messages authenticity.
