The cloud-based data outsourcing paradigm is a two-edged sword. On the one hand, it relieves data owners of technical administration responsibilities and makes it easier for them to share their data with their intended consumers. On the other side, it raises additional concerns about privacy and security. Several works have been presented to offer fine-grained data access control in order to guarantee data confidentiality against the honest-but-curious cloud service provider. To support fine-grained data access control, a number of projects have been proposed. To date, no solution has been able to handle both fine-grained access control and sensitive data publication related to time factor. To do so the project titled Time-based hybrid secured access control system for cloud data has been proposed which uses Ciphertext-policy attribute-based encryption (CP-ABE) along with Residue Number System (RNS) encryption technique for data confidentiality, security and integrity of data owner data. Also, considering the factor of time every time when the user requests for the file a new secret code is generated and give to user to decrypt the file received from data owner. The proposed system works properly with no issues.
