Abstract - Cloud storage has emerged as the most convenient and cost-effective solution for sharing, maintaining, and handling all types of data in the modern digital era. However, simply storing and sharing data is no longer sufficient - data secrecy has become an equally pressing concern. Even storage space cost is an important factor these days. Here we will use ABE for the secrecy of data and de-duplication technique to avoid data redundancy. Many users use the cloud system to store the data but sometimes data may get duplicated on the system as multiple users upload the same file. Here the situation is handled using a de-duplication filter. In the system, ABE generates a unique secret key with the help of user attributes as well as data attributes. This key is useful for secret data transmission between two parties. Here additional feature of dynamic revocation of a user is also provided if the user tries to misuse access policies provided by the authority if the user leaves the system in that case dynamic revocation and reassignment are carried out based on a set of revocation policies. In general, this system gives a complete solution for data storage, data secrecy and user revocation.
