Image Steganography using Hybrid Soft Computing Techniques–A Survey

The technique of concealing information within photos, videos, music etc. is called image steganography. Steganography excels in that it does not disclose the presence of any data as opposed to other methods such as cryptology which only try to prevent reading the said data. A major factor in assessing the steganography algorithms is its security. Steganography has subsequently earned remarkable ground in the drawn-out battle with steganalysis. Steganography must be able to resist identification by steganalysis algorithms in order to boost the reliability of image steganography. Conventional steganography methods embed secret data into an image, which eventually leaves a sign of alteration that can be detected by increasingly propelled AI-based steganalysis algorithms. In this survey, various methods for hiding sensitive data within pictures using a combination of different soft computation techniques have been explored. This is aimed at evading detection by modern steganalysis tools and achieving higher quality output.
