In the evolution of social networks and big data, secure information sharing is a crucial task. When information is shared between the user and the organization admin, security plays a key role in any business organization in terms of privacy. Though many fruitful solutions prevail to protect the data integrity and privacy, there is a huge space for novel data protection schemes where a large set of data are involved. In this article, the Cloud-Based Access Control (C-BAC) framework is proposed which can fit in any business organization application. In this C-BAC, Policy Enforcement Point (PEP) is used to avoid unwanted information sharing with the neighboring employee. C-BAC framework with RSA provides security, based on the number of employees with the data handled by the particular employee, better than the existing access control framework with asymmetric encryption standard (AES) and Rivest–Shamir–Adleman (RSA) in terms of individual information handling.
