Steganography is an art that involves secret communication by using encryption and decryption from sender to receiver through message, images, videos etc. In this work, A new Approach of image Steganography technique is proposed, This proposed Work aims to, The secret information can be concealed in 0 to N Blocks of image. Hence the user can be achieved high Secure communication. This proposed work consists of two Stages namely Encryption stage, decryption stage. The Encryption stage consists

... four steps, in the first step the text message has to convert into ASCII code. In the Second step splitting the image into number of blocks using non overlapping method. In the In Third step, We Introducing a new Method called Nearest Neighbor Filling Method (NNM) aims to hide the converted secret message into the nearest value of image block in linear manner. In the fourth step send the encrypted message with a secret key to the receiver. The receiver stage consists of four steps, in the first step the secret message has to decrypt with a secret key, In the second step the receiver has to find out the input information in the image, the third step is extracts the secret message from the image block, the final step is converting the ASCII code into the original message. Experimental result shows that the proposed approach is Simple and Better suitable to send the secret message in the stego-image.
