摘要：Personal data stored in the Cloud may contain account numbers, passwords, notes, and other important information that could be used and misused by a miscreant, a competitor, or a courtof law. These data are cached, copied, and archived by Cloud Service Providers (CSPs), often without users’ authorization and control. A Time constrained data system are been used to help the data by protecting it, by destructing the data after the specific timeout . In addition, the decryption key is also destructed after the user-specified time. In the proposed system ,we present, a time constrained data system that meets this challenge through a novel integration of cryptographic techniques with active storage based model .Time constrained data system are used to meet all the privacy-preserving goals. Compared to the system withouttime constrained data mechanism, throughput for uploading and downloading with the proposed timeout data acceptably decreases by less than 72%, while latency for upload/download operations with time constrained data mechanism increases by less than 60%.
