5.DETAILED DESCRIPTION OFTIIE INVENTION:

Cloud computing provides organizations and individuals access to powerful computing resources and vast storage capacities with minimal infrastructure investment. This model has revolutionized the way businesses operate by offering virtualized computing services that are both scalable and cost-effective. However, the widespread adoption of cloud computing comes with significant challenges regarding data security, privacy, and control, particularly when sensitive information is stored on third-party cloud servers.
The invention addresses these concerns by introducing a smart cloud computing system designed.for both individual users and organizations, with distinct modes for each. This system focuses on securing data during its lifecycle-storage, access, and transfer--within cloud environments.

Key Components of the Invention:

Hybrid AES & RSA Encryption:

To ensure strong data security, the system employs a hybrid encryption approach. AES (Advanced Encryption Standard) provides efficient and fast encryption, suitable for securing large amounts of data quickly. RSA (Rivest-Shamir-Adleman). a public-key encryption system, ensures secure key management and exchange. The combination of AES and RSA ensures both speed and security, addressing vulnerabilities associated with single encryption methods.

Individual u ml Organizational Mod os:

The system offers two distinct services based on user type:

For Individual Users: User-uploaded data is encrypted using the hybrid A IIS & R$A system and stored securely in the cloud. The locus is on ease of use. while maintaining strong encryption to protect personal data.

For Organizational Users: The system includes hierarchical access control, where every person involved in data creation or handling has distinct access permissions. The final data administrator holds the authority to grant or revoke access to the cloud-stored data, ensuring line-grained control over sensitive information.

C.'cofencing for Enhanced Security:





The system integrates geofencing technology, which allows the system, to enforce location-based access restrictions. Users can only access data from approved geographic locations, adding a physical layer of security to the digital protection offered by encryption.

QR-Code Authentication:


As an additional layer of security, the system uses QR-code authentication. Ilacli user must authenticate their identity by scanning a dynamically generated QR code. This method ensures ihm even if login credentials are compromised, unauthorized access is prevented without the correct authentication step.
Security-aware Scheduling and Data Access:

For organizational users, the. system integrates security-aware scheduling, ensuring that sensitive data processing tasks are prioritized based on predefined security policies. 'I'his approach mitigates the risks associated with.scheduling sensitive applications in a cloud environment where data could be vulnerable during high-traffic periods. •

Addressing Limitations of Fxisting Security Technologies:

Existing solutions like homomorphic encryption, secret sharing, and secure multi-party computing often struggle, with scalability, excessive communication rounds, and high traffic load. The invention overcomes these limitations by streamlining encryption and authentication processes. The hybrid
encryption system reduces the overhead, making it suitable for both small-scale individual users and large organizations.

Scalability and Efficiency:

This system is designed to scale efficiently, allowing it to handle varying amounts of data while maintaining robust security. By minimizing the communication overhead and traffic load compared to traditional security solutions, the sysiem ensures that both real-time and large-scale data transfers can be performed securely.

How the System Operates:

For Individual Users:

Once the user uploads their data to the cloud, the system automatically encrypts it using the hybrid AES & RSA algorithm. The data is then stored securely on the cloud, and can only be accessed by the user with proper authentication. Geofencing and QR-code verification further ensure that the data is accessed from secure locations and by authorized users only.

For OrganizaIional Users:
Data ;s encrypted upon upload and stored in the cloud. Each individual with access to the system has a unique role and corresponding access rights, assigned by the administrator. The administrator oversees data access permissions and can revoke or grant rights as needed. Geolcncing prevents unauthorized access from unapproved locations, and QR-code authentication ensures that even users within the allowed geographic area are properly authenticated.
