1. Cloud-based Antivirus Project Proposal By Yuli Deng, Guofu Xiong

2. Traditional Antivirus and its disadvantages Traditional Antivirus heavily relied upon signature based detectionTraditional Antivirus heavily relied upon signature based detection Require to update virus library frequentlyRequire to update virus library frequently Heavy load on the computing resources, killer of netbook and smartphoneHeavy load on the computing resources, killer of netbook and smartphone Single antivirus engine, never the best, some time do false actionSingle antivirus engine, never the best, some time do false action Presents to much prompts and decisions to inexperienced usersPresents to much prompts and decisions to inexperienced users

3. Cloud Security Concept Collect sample files on client Upload files to the cloud Cloud analyze the file, make decisions and report results to the client Client take actions

4. Features of Cloud-based Antivirus Behavior-based virus scan File emulation Always up-to-date Lightweight host agent --- Computing resource needs is low Multiple anti-virus engine Intelligent

5. Overall Design Goal Build a demonstration program to study the concept of Cloud-based Anti-Virus

6. Some Technology Goals A simple server utilizes current online Cloud-base AV engine (Symantec, Trend, etc…) An windows client program C++ is expected to be used for coding currently

7. Overall Structure
