Ushbu maqolada maʼlumotlar uzatish va saqlash jarayonida yuzaga keladigan xatoliklarni aniqlash hamda tuzatish masalalari statistik yondashuv asosida tadqiq etilgan. Taklif etilgan A, B va C algoritmlar mos ravishda matnli, raqamli va aralash maʼlumotlarda harflar va raqamlarning chastotalarini hisoblash orqali xatoliklarni aniqlash va avtomatik tuzatish imkonini beradi. Har bir algoritm ikki oʻlchovli massivlar yordamida nazorat qiluvchi strukturalarni yaratib, maʼlumotlarning aniqligini ta’minlaydi. Ushbu algoritmlar bir, ikki va uch karrali xatolarni aniqlashda yuqori samaradorlikka ega bo‘lib, aniqlay olmaydigan xatoliklar ehtimoli juda past (Pn < 0.2·10⁻⁶) ekani ko‘rsatilgan. Statistik asoslangan bu yondashuvlar zamonaviy axborot tizimlarida maʼlumotlar ishonchliligini oshirish va axborot xavfsizligini taʼminlashda muhim ahamiyat kasb etadi.
