In today's connected world, the protection of digital data and image compression has arisen as a major concern for the general public and an important topic of research. This paper proposes a unique scheme of scalable coding of transmitting and receiving images in an extreme protected way using wavelet transform. In the encryption phase, the original pixel values are masked by a modulo-256 addition with nonrandom numbers that are derived from a secret key. Then, the encrypted data are decomposed into several parts and each part is compressed as a bit stream.
