Abstract of privacy preserving :

With the increasing reliance on cloud storage, ensuring the security and privacy of user data has become a critical concern. This postgraduate student project, “SEPDP,” aims to address these challenges by proposing a Secure and Efficient Privacy-Preserving Provable Data Possession system. The proposed system enhances the existing methods for verifying data possession in cloud storage while maintaining user privacy.

Existing System:

Current data possession verification techniques in cloud storage often lack robustness and may compromise user privacy. Traditional methods may expose sensitive information during verification, leading to potential security vulnerabilities.

Proposed System:

SEPDP introduces a novel approach to data possession verification that prioritizes both security and user privacy. The system employs advanced cryptographic techniques to ensure the confidentiality of user data during the verification process. By leveraging provable data possession protocols, SEPDP guarantees the integrity of stored data without compromising users’ privacy.

System Requirements:

The SEPDP system requires minimal resources for deployment. The server-side infrastructure should include a reliable cloud storage platform. Clients can access the system using standard computing devices with internet connectivity.

Hardware and Software Requirements:

  • Server: Cloud storage infrastructure (e.g., AWS, Azure)
  • Client: Standard computing devices (e.g., laptops, desktops)
  • Software: Java programming language, cryptographic libraries, cloud storage APIs


SEPDP follows a client-server architecture. The client interacts with the cloud storage platform using the SEPDP application, which encrypts and uploads data securely. The server hosts the data and performs provable data possession verification. The architecture employs a layered security approach to protect user data during transmission and storage.

Technologies Used:

  • Java: A programming language for system development
  • Cryptographic libraries: Ensuring data confidentiality and integrity
  • Cloud storage APIs: Interfacing with the chosen cloud storage platform

Web User Interface:

SEPDP features a user-friendly web interface for clients to interact with the system. The interface allows users to upload, download, and manage their data securely. Additionally, it provides real-time feedback on data possession verification status, enhancing the user experience.

The SEPDP project contributes to the advancement of secure and privacy-preserving data storage solutions, offering a robust framework for users to confidently store and retrieve their data in the cloud while ensuring the integrity and confidentiality of their information.
