—Steganography is a way of sending hidden
messages in such a way that no one, apart from the sender and
intended recipient, suspects the existence of the message. There
exist many methods for digital image steganography. But most
of the existing techniques are based on lossy approach. And the
major challenges of steganography are security of hidden
communication and the size of message that can be embedded in
an image. So, this paper is intended to propose an image
steganography technique based on matches between cover
image and secret data. This proposed method maintains the
cover image as such and has unlimited capacity of payload.
—Lossless steganography, secure steganography,
search partition size, unlimited payload.
