Analysis and Implementation of Image Steganography by Using AES Algorithm

Popular cryptographic technology called Advanced Encryption Standard (AES) enables secure data transfer over the internet. It is used for a variety of purposes, such as secure data transfer, mobile phone encryption, and encryption of extremely sensitive data. It operates in terms of blocks, or chunks, of data. Steganography is the process of hiding data in another sort of data, such as a digital image. If a user wants to utilize a cryptographic method to conceal encrypted data in an image, such as AES, it is essential that the method be impervious to all possible attacks. This study has analyzed the possibility to hide data inside digital photos by utilizing encryption techniques like AES. The performance comparison of AES and Data Encryption Standard (DES), a full Python implementation of the AES for image steganography is also presented. To illustrate how each method performs, experimental results are provided. The Advanced Encryption Standard can be programmed in software or built with pure hardware.
