  With the development of imaging methods in wireless communications, enhancing
the security and efficiency of image transfer requires image compression and
encryption schemes. In conventional methods, encryption and compression are two
separate processes, therefore an adversary can organize his attack more simply
but if these two processes are combined, the output uncertainty increases. As a
result, adversaries face more difficulties, and schemes will be more secure.
This paper introduces a number of the most important criteria for the
efficiency and security evaluation of joint image encryption and compression
(JIEC) schemes. These criteria were then employed to compare the schemes. The
comparison results were analysed to propose suggestions and strategies for
future research to develop secure and efficient JIEC schemes.
