A Study on Authentication System Using QR Code for Mobile Cloud Computing Environment

摘要: In cloud computing environment, users use authentication system for being provided the whole or part of needed resources directly from servers, and authentication, thousands suatus bit are necessary. The problems is that status information should be searched under centural authority, searching process causes high network bandwidth, delay, congestion. This paper suggests appropriate mobile environment using QR code, a typical 2-dimensional code technology suitable to display user through its strengths such as data integration, compressibility error correction capability. Then, it authorize with totally new vs type set having 3 kinds by converting different versions storing each in distributed server circulation-loop way.
