SPIRT compression on encrypted images

A novel technique is proposed for encryption and compression. Here an image is first encrypted using the stream cipher and then compressing the encrypted image using SPIHT. The panorama here stands for using the highly efficient encryption standard and unabating experience of compression techniques. The stream ciphers are chosen for their high encryption rate and they are mainly of bit-by-bit encryption. They don´t simply mean encryption but provides authenticity and integrity. Then on the compression section we prefer SPIHT for their unique factors such as larger bit depth, progress from lossy to lossless compression, unrestricted dimensions in image, etc. This paper focuses mainly on highly secure encryption and high compression rate using SPIHT method in Larger Images.
