Description

Technical Field

[0002] With the rapid development of computer technology and Internet applications, data and applications are growing at a geometric rate, and people's demand for data storage is also increasing. Driven by this background, cloud storage services have been welcomed by more and more users due to their convenience and cost savings. However, users will lose absolute control over their data, which will inevitably cause users to pay attention to their security. At present, the mainstream method to ensure data confidentiality is to encrypt the data. The amount of data stored in the cloud is often large, so an important way to retrieve data is through keyword indexing. However, encrypted data increases the difficulty of keyword indexing. At the same time, the method of specifying plaintext keywords for ciphertext data also discloses the privacy of data owners to untrustworthy service providers to a certain extent. In order to solve this problem, it is necessary to study the indexing method for ciphertext data, while ensuring confidentiality and privacy, and effectively indexing the required data. However, the existing indexing device cannot reasonably adjust the height of the indexing device body according to needs, the scope of application is limited, and the working effect is not very ideal. For this reason, we propose a GIS-based urban information model rapid indexing system. Summary of the invention
