Abstract: Accessible encryption uses a cloud server to allow users to browse over encrypted data without decrypting it. Single watchword-based accessible encryption enables a client to view a subset of records that contain the client's advantage's catchphrase. In this research, we describe a single watchword-based open encryption scheme for applications where distinct information owners send their data and afterwards allow different clients access to the data. The plan uses quality-based encryption to enable clients to access a selected subset of data from the cloud without disclosing their access rights to the cloud server. The plan is shown in the arbitrary prophet model to be adaptively secure against picked watchword attack. We implemented the strategy on a Google cloud example, and the demonstration of the strategy was successful in real applications.

Keywords: Cloud server, Encryption, Decryption, Prophet model.
