Query: A New Steganographic Technique Matching the Secret Message and Cover
  image Binary Value   Steganography involves hiding a secret message or image inside another cover
image. Changes are made in the cover image without affecting visual quality of
the image. In contrast to cryptography, Steganography provides complete secrecy
of the communication. Security of very sensitive data can be enhanced by
combining cryptography and steganography. A new technique that uses the concept
of Steganography to obtain the position values from an image is suggested. This
paper proposes a new method where no change is made to the cover image, only
the pixel position LSB (Least Significant Bit) values that match with the
secret message bit values are noted in a separate position file. At the sending
end the position file along with the cover image is sent. At the receiving end
the position file is opened only with a secret key. The bit positions are taken
from the position file and the LSB values from the positions are combined to
get ASCII values and then form characters of the secret message
