A high embedding capacity image steganography using stream builder and parity checker
Md. Olioul Islam · 2012
Steganography is one of the arts and sciences of securing or hiding secret information in some cover media. In the present study, a new steganography technique is developed to hide large data in Bitmap image using stream builder and parity checker. This method uses the concept of odd and even parity for embedding and extracting of secret message. This method is an improvement of Least Significant Bit (LSB) method for hiding information in images. The proposed method can hide large data in a single Bitmap image retaining the advantages and discarding the disadvantages of the LSB method.
