In the world today, data encryption is essential to
maintain privacy. We propose a technique in which the color
table is used to generate a picture carrier, the carrier image
is added to the original image. The encrypted image obtained
is unclear and can’t be seen. To make it even more secure
model SCAN pattern is used to blend the pixels of the image.
The resulting image is decrypted using the inverse of the scan
pattern. Thus the carrier image and original image is
obtained at the output.

Picture Carrier, SCAN Pattern
A combined and effective method has been proposed in
this paper for image encryption using carrier image and
SCAN-mapping method. This paper has presented a
concept of combination of nibble value of a characters is
used as a mapping function to generate carrier image
,merging of carrier image and original image generate
level 1 encryption . Applying scan patterns on level 1
encryption gives double layer protection to secretly send
original image.
