Cloud Computing Issues, Challenges, and Needs: A Survey

Abstract

Cloud computing represents a kind of computing that is based on the sharing of computing resources instead of possessing personal devices or local servers for handling several applications and tasks. This kind of computing includes three distinguished kinds of services provided remotely for clients that can be accessed by using the Internet. Typically, clients work on paying annual or monthly service fees for suppliers, in order to gain access to systems that work on delivering infrastructure as a service, platforms as a service, and software as a service for any subscriber. In this paper, the usefulness and the abuse of the cloud computing are briefly discussed and presented by highlighting the influences of cloud computing in different areas. Moreover, this paper also presents the kinds and services of cloud. In addition, the security issues that cover the cloud security solution requirements, and the cloud security issues, which is one of the biggest issues in recent years in cloud computing were presented in this paper. The security requirement that needs by the cloud computing covers privacy, lack of user control, unauthorized secondary usage, and finally data proliferation and data flow. Meanwhile, the security issues cover including ownership of device, the trust issue and legel aspects. To overcome the security issues, this paper also presents the solution at the end of this paper.

Iris Image Watermarking Technique for Security and Manipulation Reveal

“…The iris images can be stored or shared via open access networks or the internet or stored on the cloud for many purposes. The stored or shared images can face some security challenges, such as the lack of user control, unauthorized usage or manipulation of images, and reproduction attacks [6], [32]- [34]. Considering the image authentication requirement and the abovementioned security issues, it will be very useful to present a new technique that can reveal manipulations in the IR.…”
