Traditional privacy protection schemes are usually based on cipher technology, but these kinds of methods cannot effectively resist attacks from the inside of a cloud server. In order to achieve the goal problem, the motive of a three-layer storage framework supported fog computing. The future framework can both take full advantage of cloud storage and protect the privacy of knowledge. The hash-Solomon code algorithm is meant to cleave data into different parts. Then, this can add a small part of data in the local machine and fog server in order to protect privacy. With the explosive growth of disorderly data, cloud storage technology gets more attention and better development. However, in Education, Financial, and Healthcare storage schema, users’ data is totally stored in cloud servers.
