Image steganography using 24-bit bitmap images

A high embedding capacity image steganography using stream builder and parity checker

“…The party from which the message is hidden Image steganography systems can be considered secure if it is impossible for attackers to detect the presence of a hidden message in the stego image by using any accessible means [3]. Steganographic capacity is the maximum number of bits that can be embedded in a given cover image with a negligible probability of detection by an adversary [3]. Steganography systems, mainly used for secret communication, aim to maximize the steganographic capacity and minimize the perception of hidden messages in stego images [8].…”

“…The commonly used terms while working with information hiding techniques are given in Table-I [2]. The party from which the message is hidden Image steganography systems can be considered secure if it is impossible for attackers to detect the presence of a hidden message in the stego image by using any accessible means [3]. Steganographic capacity is the maximum number of bits that can be embedded in a given cover image with a negligible probability of detection by an adversary [3].…”

“…Since the rise of the Internet one of the most important factors of information technology and communication has been the security of information [2]. Steganography is the practice of hiding private or sensitive information within something that appears noting out of usual [3]. The term "Steganography" came into use in 1500's after the appearance of Trithemius' book on the subject "Steganography" [4].…”

Variant of LSB Steganography Algorithm for Hiding Information in RGB Images

“…Saha, et. al., [10] proposed a scheme for hiding messages in 24-bit bitmap image where most frequent pixel values and modification of those pixels are calculated to hide the information. It is observed that efficiency of the approach is highly attributed to the number of eligible pixels, with the moderate number of eligible pixels producing better results.…”

Improving the non-filtering steganographic algorithm using LSB verification method

“…That mean it is not capable to identify a very small difference in color, and this characteristic has been taken as an opportunity in Image Steganography. Furthermore, digital images can easily be used as cover files without any suspicion because of their presence everywhere on the Internet [6]. Each image hiding system consists of an embedding process and an extraction process.…”
