Prevalent current day scenario with the predominant accelerated utilisation of the internet, is witnessing the increased interest in the method of transmitting concealed secret information (information hiding) via several variant techniques. One of the eminent and significant form of information hiding is Steganography. Hence, Steganography involves scientific techniques in concealing information inside the host object, which serves as the transporter of the hidden information, to be communicated in a secured undetected and safe form to another party. It engages multitudinous forms of host carriers that could be utilised in the form of texts, audio, visual images, protocols and DNA. Due to its frequent use on the internet, digital images are the favoured form of carrier host documents.. This study reviews the various latest related publications pertaining to image Steganography within the spatial domain, by assessing, accumulating, synthesising and analysing the difficulties, problems and issues faced in these different studies.. The objectives of this study is to execute a review as to render a summary of image Steganography, and to compare certain elements between the selected studies. Discussions will be made in accordance to the selection of pixel for the images, the capacity of the payload and the embedding algorithm, which will enable significant research issues for future researches. It is also aimed in the furtherance of securing a more robust Steganography technique.
