Cloud computing is a revolutionist computing paradigm, which enables flexible, on-demand, and low-cost utilization of computing imaginations, but the information is outsourced to some cloud hosts, and sundry secrecy concerns emerge from it. Sundry schemes predicated on the attribute-predicated encryption have been proposed to secure the cloud storage. However, most work fixates on the information contents secrecy and the access control, while less care is paid to the privilege control and the individuality secrecy. In this paper, we present a semi incognito privilege control scheme AnonyControl to address not only the information secrecy, but additionally the utilizer individuality secrecy in subsisting access control schemes. AnonyControl decentralizes the central ascendancy to inhibit the individuality leakage and thus achieves semi anonymity. Besides, it additionally generalizes the file access control to the privilege control, by which privileges of all operations on the cloud information can be managed in a fine-grained manner. Subsequently, we present the AnonyControl-F, which plenarily averts the individuality leakage and achieve the full anonymity. Our protection analysis shows that both AnonyControl and AnonyControl-F are secured under the decisional bilinear Diffie–Hellman posit, and our functioning evaluation exhibits the feasibility of our schemes
