This document discusses security and privacy issues in cloud computing and proposes solutions. It outlines the differences between public and private clouds, with private clouds residing inside an enterprise's firewall and providing full security through antivirus software and access only by registered users, while public clouds have no control mechanisms and data can be publicly available and accessed by fraudulent users. Current solutions like antivirus and VPNs increase overhead on every update and do not prevent unauthorized access. The proposed solution is an extra cloud access code mechanism that is managed centrally and only requires one-time updates, controlling traffic and only allowing authorized users via access codes.

2. Introduction What is Cloud Computing? SaaS PaaS IaaS Benefits Cost - Decrease Time - Decrease Sales - Increase

3. Public & Private Clouds Private Cloud Resides inside Enterprise firewall Full proof security with Antivirus Software Only registered user access it – Monitored Access Public Cloud Fraud user access No Control on Public Cloud Data Available publicly

4. Security and Privacy Issues in Current Cloud Computing System Private Cloud No Security Issues No Privacy Issues Public Cloud No Control Mechanism Data access without any permission Personal Data used by any fraudent user

5. Current Solution available in Market Antivirus Cloud Network Security Through VPN (Virtual Private Network) (Secure Transmission Channel)

6. My Solution  Extra Cloud Access code mechanism Administrator access Updating only once

7. Compare Solution Current Solution Increase Overhead on Every update Increase Traffic No Authorized Access Extra Cloud Working on SaaS Concept, one time updation Manage Traffic via central Location Authorized Users via Access Code Mechanism
