Currently cloud computing environments have come up with a serious problem known as security which is in terms of Confidentiality of Data, Integrity of the Message and Authenticity of the users (CIA). Since user’s personal data is being stored in an unencrypted format on a remote machine operated by third party vendors who provide various services, the impact of user’s identity and unauthorized access or disclosure of files are very high. Though we have various techniques and algorithms to protect our data from hackers and intruders still cloud environments are prone to other attacks. In this paper, a novel approach is implemented to protect user’s confidential data from third party service providers, and also to make sure that the data is not disclosed to any unauthentic user or the service provider even, in any cloud environments. This approach provides a multi-level security in three aspects: 1) User authentication for “authorization” to enter the network, 2) Image Sequencing password for “authentication” wherein it is proved that the identity is original user, and 3) RSA algorithm to encrypt the data further for providing “data integrity”. Thus this approach provides an overall security to the client’s personal data and the major issue of confidentiality, integrity and authenticity is fully solved. Implemented results are represented to illustrate that our approach has a reasonable performance.

Excerpt from the Dissertation
3.1 Problem Formulation
Now days, information security has been a vital issue in cloud computing environments. Clouds don't have any borders and therefore the information may be physically set anyplace in any information centre across the network geographically distributed. That the nature of cloud computing raises serious problems relating to user authentication, info integrity and confidentiality. With the cloud model, you lose management over physical security. In a public cloud, you're sharing computing resources with different corporations. In a shared pool outside the enterprise, you do not have any data or management of wherever the resources run. Storage services provided by one cloud seller could also be incompatible with another vendor services. Information integrity is assurance that the information is consistent and proper. Guaranteeing the integrity of the information very implies that it changes solely in response to licensed transactions. The cloud service supplier for cloud makes certain that the client doesn't face any drawback like loss information or data thievery. There’s conjointly an opportunity wherever a malicious user will penetrate the cloud by impersonating a legitimate user, there by infecting the complete cloud.

Frequently Asked Questions
What is the primary focus of this research?
The research focuses on implementing a multi-level security approach in cloud computing to address critical issues regarding the Confidentiality, Integrity, and Authenticity (CIA) of user data stored on remote servers.
Which core technologies are utilized in this approach?
The solution integrates image-based sequencing for secure user authentication and the RSA algorithm for robust data encryption and integrity verification.
What is the main research objective?
The primary objective is to enhance the overall security and reliability of cloud environments by protecting sensitive data from third-party service providers and malicious attackers.
How is the effectiveness of the proposed security system verified?
The effectiveness is demonstrated through a practical implementation using the NetBeans environment, showing how the system reacts to unauthorized access attempts and validates legitimate data storage and retrieval.
What are the major threats covered in the study?
The study addresses common threats such as data breaches, data loss, service traffic hijacking, insecure APIs, malicious insiders, and authentication attacks.
Which methodologies are highlighted in the literature review?
The literature review covers proactive models, privacy-preserving public auditing, trust-based innovations, and data storage security techniques like Sobol sequence integration.
How does the "image sequencing" mechanism function?
It provides an extra layer of authentication at the user end where the user must input a numeric sequence corresponding to specific positions of images, which shuffle with each session to prevent replay attacks.
Why is RSA encryption used in this project?
RSA is employed to ensure data integrity and confidentiality, allowing the user to encrypt information locally before storage, ensuring that the cloud service provider cannot read the original content.
