Problems related to the protection of information from interference are relevant in a variety of practical applications. The information itself can be text, graphic, contain video clips. Interference can be unintentional as well as specially created by cyber criminals. To process and transmit information in practice, various noise-resistant codes are used. The paper discusses the characteristics of some similar stakes: Hamming code, code, reed-Muller, BCH code Bose-Chowdhury-Hoquinghem. The results of comparison of characteristics-correcting codes are shown. An illustration of the encoded text and those bits that have been distorted. A graphical dependency is given to illustrate the dependence of the number of corrected errors on the number of errors that were added to the original message for the three selected codes. The results of studies of the characteristics of redundancy of codes with different files are shown. The BCH and reed-Muller codes were chosen for testing. Txt, midi, wmv and mpeg-2 files were analyzed. A table on the results of research, which shows how the file size, as well as its appearance, have an impact on redundancy. It is established that Hamming and reedMuller code fix single errors well, BCH code is suitable for correcting various errors.
