Abstract

Data security is challenging. Oftentimes it is desired to be able to encrypt the data, yet still search the data efficiently. One manner of achieving the goal is to store the data and keyword metadata separately. The data and keyword metadata can even be encrypted differently where the data has a stricter encryption compared to the keyword metadata. Furthermore, if a security threat is detected, the encryption type can be changed to a more restrictive encryption. Once the security threat has passed, the encryption can be changed to a less restrictive encryption.
