LSB Steganography Using Pixel Locator Sequence with AES
This work addresses the problem of secure data hiding within images for applications such as medical, military, and copyright information, offering an incremental improvement in security.
This paper proposes a method for image steganography that hides secret data within the Least Significant Bit (LSB) of image pixels. It enhances security by encrypting both the data and its pixel locations using AES, moving beyond linear data storage.
Image steganography is the art of hiding data into images. Secret data such as messages, audio, images can be hidden inside the cover image. This is mainly achieved by hiding the data into the LSB(Least Significant Bit) of the image pixels. To improve the security of steganography, this paper studied data encryption with AES(Advanced Encryption Standard) and LSB based data hiding technique with advanced user-defined encrypted data distribution in pixels other than the common linear computational method of storing data in a linear form. This data distribution file will contain the location of the data(in form of pixel numbers) to be encrypted/decrypted which is further encrypted with AES thus providing double encryption for data and its location stored over pixels. Steganography has many applications such as medical, military, copyright information, etc.
