Annotatsiya
Ushbu maqolada genetik algoritmlar yordamida steganografik tizimlarning
samaradorligini oshirish masalasi ko'rib chiqiladi. Steganografiya — ma'lumotlarni
boshqa media fayllari ichida yashirish san'ati bo'lib, axborot xavfsizligi sohasida
muhim ahamiyat kasb etadi. Taklif etilgan yondashuv genetik algoritmlarning qidiruv
va optimallashtirish imkoniyatlaridan foydalanib, piksel tanlash jarayonini
avtomatlashtiradi va yashirish sig'imini oshiradi. Tajribalar natijasida an'anaviy LSB
(Least Significant Bit) usullariga nisbatan PSNR ko'rsatkichi 3.2 dB ga oshgani va
yashirilgan ma'lumot hajmi 18% ga ko'paytirilgani isbotlandi. Taklif etilgan metod
raqamli tasvirlarga nisbatan qo'llanilgan bo'lib, kriptografiya bilan birgalikda
ishlatilganda axborot uzatish xavfsizligini sezilarli darajada mustahkamlaydi.
