Abstract
Digital images are used in different applications like aerospace, military, science
and many more applications. The image compression is important in data storage and data
transmission through an untrusted channel to make use of efficient network bandwidth. In
most of the case image compression is done by network provider. This leads to data loss
while compressing, here we will not able to get exact image even though it is lossless
compression if we encrypt and decrypt. To overcome this problem, we have designed an
efficient image encryption and compression. The image compression is done by transmitter
after the encryption, which gives lossless image at the receiver side. To encrypt the image,
the prediction error and random permutation techniques were used and the GAP algorithm
is used to find the prediction error. Adaptive Arithmetic coding algorithm is used to
compress the encrypted image for lossless image. In this work, the encrypted and
compressed image is decompressed and decrypted without any loss of data at the receiver
side.
