The process of data exchange relies heavily on attribute-based encryption. The secret key can be shared with other users for transactions and it does not contain any user-related data. The attribute authority creates the secret key from a collection of attributes. It is difficult to tell whether the authority or the other nodes are providing the altered private key. When the structure of access control in a dispersed network is flawed, sensitive information is exposed. The efficiency of attribute-based encryption is a hindrance in its applications. Data is more reliable and approved because to blockchain technology. In the suggested system a multi-authority attribute based encryption is been implemented. The attribute bloom filter is used in access control and to hide attributes. The performance and security analysis reveals a safe and efficient privacy system.
