The present research presents an innovative access control system with the aim of enhancing privacy and optimizing cloud storage operations.The main aim of this framework is to provide cloud service providers an economically viable approach to ensuring the security, integrity, availability, and privacy of data, while also maintaining customer trust.The solution being presented focuses on implementing a strong authentication system that ensures the security of data both during its storage and transit inside cloud environments.The main goal of this framework is to enhance cost efficiency in storage while ensuring the preservation of data security and integrity.The recommended methodology involves the compression of high-resolution photographs, leading to an estimated decrease of around 60% in the amount of data storage.The data that is in a fragmented state is then subjected to encryption using a proprietary private key, therefore forming a security framework consisting of two tiers.The process of decrypting and reconstructing data back to its original format is exclusively limited to those who have been granted authorized access.Furthermore, a distinct signature is produced in order to authenticate the integrity of the data.If there are any attempts made by unauthorized organizations to change the data, the audit process is designed to detect any instances of compromised data.When data is sent to the cloud by users, a digital signature is formed via the use of asymmetric keys and the user's private key for the purpose of generating such digital signature.The use of this model not only decreases expenses related to data storage by using effective data compression methods, but also offers a welldefined data access protocol that prioritizes the utmost significance of safeguarding data privacy.The experimental phase produced findings that indicate the superiority of the proposed scheme in comparison to current systems across several benchmarks.The use of a framework that optimizes storage while emphasizing access control centered on privacy may effectively assure the safe storage and sharing of data, particularly in collaborative cloud computing settings.
