摘要：

A fine-grained data access control algorithm was presented on this model. Data owners divided a data file into multiple data blocks by data content according to different clients and clients needs. These data blocks were fine-grained, and the data owner generated an authorized access control code for the data visitors every time. Cloud computing platform manage different users different read and write permissions for data access request control based on the authorized access code. This algorithm avoides the data leaking weakness.
