Steganography: DCT Coefficients Reparation Technique in JPEG Image
Due to the ever-growing usage of the computer, it has led to a rapid increment in the data that is being exchanged, published and stored in an assortment of digital form. This phenomenon has urged an active participation in the research area of the security domain. One of the main areas of this security domain in providing confidentiality, authentication and data integrity is steganography. This paper proposes a steganography technique for hiding information in images through reparation technique in frequency domain. The purpose of reparation is to correct any static deviation from the cover image after embedding hidden message. The proposed technique is able to withstand visual attacks and statistical attacks. Thus, it can be used to strengthen the security of a steganography system. The proposed technique will be tested by using chi-square steganalysis. Keywords Steganography, steganalysis, discrete cosine transform, image histogram, Chi-square
