A Comprehensive Study of Image Steganography Techniques

Dr. Israa T. Ali ,Shaymaa Jawad

Abstract:Transmitting images confidentially from sender to an authorized receiver through an insecure (public) channel is a challenging task. Therefore, several methods are developed to protect important information for safe and secure communication. There are three main technologies used for securing digital data: watermarking, steganography and cryptography. Steganography and watermarking could be considered within the same field (information hiding). This paper presents a comprehensive study for various methodologies in the field of image steganography. Each methodology has its bad and good points, therefore, a part of advantages and drawbacks are also discussed as a comparative study to help future researchers by providing a review of the existing techniques. Keywords: image steganography, spatial domain, transform domain, cover image, and stego image
