Abstract: A global user base consisting of millions groups together for internet access. User information along with data tampering and application intrusions are easy to achieve because of these weaknesses in the system. A proposed security system implements hybrid protection features which combine data hiding with three-stage graphical passwords and file split and merges techniques to protect users. The AES algorithm serves as our proposed approach for securing the daily key owner's private information. The proposed method works to stop intrusions along with delivering complete user privacy protection for data. Our project contains 3 stages of graphical passwords for secure authentication implementation. Our proposed security system implements three stages of authentication which defend both users and stops unauthorized intruders from logging in. The project implements authentication security through traditional login with username and password and also includes color sequence verification followed by graphical image matching as the final authentication stage. Human beings tend to recall images more easily than written text according to psychological research findings. The data owner file gets encrypted by AES encryption while split and merge implementation is applied. The file of the data owner becomes three separate parts that get stored safely in cloud storage to protect against unauthorized access of cloud service providers.
