Insertion of message in 6th, 7th and 8th bit of pixel values and its retrieval in case intruder changes the least significant bit of image retrieval in case intruder changes the least significant bit of image

A new method for insertion of message using 6th, 7th and 8th bits of pixel values of an image is developed. This method is an improvement over the earlier method [7] in which 6th and 7th bits of pixel values of an image were used. A method to retrieve the message is also given. Another advantage offered by this technique is that the message can be retrieved even if the intruder changes the least significant bit of all the image pixels in which message has been embedded.
