As in last few years, quantum cryptography appears to overcome the current challenges of time and quality of the encryption systems and offer new fields of cryptography. This paper briefly introduces the quantum cryptography from the basic ideas, theoretic foundation, as well as analyses some innovative papers where used quantum theory in the field of cryptography especially for image encryption. Formerly, current work illustrates the accomplishments of quantum cryptography in image encryption methods and its upcoming progress schemes. Conclusively, its motivation to make a general view that represents a new trend in cryptography scheme can be developed on the benefits of the quantum cryptography.

The rapid development of smart phone devices and users' satisfaction with them, also have storage and accounting capabilities that compete with computers. Smart phones carry a lot of personal information and important financial information, so they are vulnerable to theft or access by unauthorized persons to that information. Increased need for ways to protect that information. Smartphones have several built-in sensors that facilitate the capture of biometrics and behavioral traits This paper reviews the authentication techniques for mobile, as it covers a comprehensive survey on authentication methods and comparison between these techniques..
