Image Compression and Encryption Technique: Review Paper

Abstract

Compression is reducing size of data for storage and transmission bandwidth. Image compression technique is lossless and lossy, the technique is to keep or reduce output of decompress format compare to original source. The lossless and lossy compression technique will have their process and algorithm to completed their objective compression and decompression. Encryption is about securing image exchanging via internet, thus prevent to be accessed by unauthorized users. Basic encryption method is symmetric and asymmetric.
