Abstract

The Internet and cloud services are widely used in transmission of large amounts of data over open networks and insecure channels, exposing private and secret data to serious situations. Thus ensuring that information transmission over these mediums is safe and secure has become one of the most important issues in the data security field. To keep unauthorized persons away from the transmitted information, a variety of techniques have been introduced, and steganography is one of them. As a technique for covert communication, steganography aims to hide secret messages in a normal message achieving the least possible statistical detectability and without drawing suspicion. Steganography techniques can be applied on a various types of data such as text, image, video, and audio data. This chapter presents a general and brief introduction to exemplify the tremendous progress achieved recently in the topic of image steganography to help readers and researchers in discovering new research gaps in the theoretical foundations and practical implementations of steganography techniques.

1.1 Introduction

Steganography has been used from ages and has been set its roots from ancient civilizations (e.g., Greece, Egypt). The word steganography is a composite of two Greek words: Steganos which means “covered” and Graphia which means “writing”. In the 5th century BC, Histaiacus shaved a slave's head and tattooed a message on his skull, and the slave was dispatched with the message after his hair grew back [1]. Cardan (1501–1576) reinvented a Chinese ancient method of secret writing, where a paper mask with holes is shared among two parties, this mask is placed over a blank paper, and a sender writes the secret message through the holes, then takes the mask off, and fills the blanks to display the message as an innocuous text. This method was approved to Cardan Grille [2]. Null Ciphers, Microdots, and invisible ink methods were also very popular steganographic methods during World War II. These hiding secret message methods have been used in various forms for thousands of years [3].

Nowadays, digital steganography can be defined as the art of hiding secret messages behind the innocent looking digital media [4]. Jessica [2] defined steganography as the art of concealed communication where the existence of a message is secret. Other researchers define digital steganography as a task of hiding digital information in covert channels so that one can conceal some information and prevent detection of this hidden information [5]. Steganography can be defined as a science of obscuring a message in a carrier (host object) with the intent of not drawing suspicion to the context in which the messages is transferred [6]. In general, there are several types of digital mediums, which can be used for hiding secret information such as image, video, audio, and text (linguistics) as shown in Fig. 1.1. These digital mediums have different characteristics to embed secret information [7], where the best medium for embedding secret information must have two features: the medium should be popular, and the modification in this host (cover) should be invisible to any unauthorized third party.
