In the realm of cloud storage systems, ensuring robust security and efficient data sharing is a critical concern due to the increasing volume and sensitivity of stored information. This study proposes a novel three-factor approach designed to enhance both data sharing and security in cloud storage environments. The proposed mechanism integrates three key factors: authentication, encryption, and access control, to create a comprehensive framework that addresses common security vulnerabilities and operational challenges.

The first factor, authentication, employs multi-factor authentication (MFA) to verify the identities of users accessing the cloud storage system. This ensures that only authorized individuals can initiate data sharing activities. The second factor, encryption, involves advanced cryptographic techniques to protect data both in transit and at rest. By encrypting sensitive information, the mechanism safeguards against unauthorized access and data breaches. The third factor, access control, utilizes granular permission settings to regulate user access based on roles and responsibilities, thereby minimizing the risk of data exposure.

The study details the design and implementation of this three-factor approach, including the technical specifications and integration processes with existing cloud storage infrastructures. Through a series of simulations and real-world case studies, the effectiveness of the proposed mechanism in enhancing data security and facilitating efficient sharing is evaluated. Results demonstrate a significant improvement in the protection of sensitive data and the management of user access, compared to traditional single-factor security models.

This research contributes to the field of cloud storage by providing a practical and effective solution to the dual challenges of data security and sharing. The proposed three-factor approach offers a scalable and adaptable framework suitable for various cloud storage applications, from personal data management to enterprise-level storage solutions. The findings underscore the importance of adopting multi-faceted security strategies to safeguard cloud-based information and enhance overall system integrity.
