Problems solved by technology

[0005] Most of the existing data verification patents based on the Merkle hash tree are for the data stored by the user and the verification of whether the stored data is damaged and the integrity is verified when the stored data is moved in the cloud storage state, and there is no verification when the user calls Or when renting the corresponding data model, verify the data model and check whether the correct data model is called. At the same time, when constructing the hash tree, it is simply constructed without considering the efficiency of the verification

Abstract

The invention discloses a data model verification system and method based on a Merkle tree structure. The system comprises a user unit, a model management unit and a data storage center. The user unit comprises a login module, a permission verification module and a first model verification module. The model management unit comprises a management module and a second model verification module. The data storage center comprises a data preprocessing module and a Merkle tree structure module. According to the data model verification system and method based on the Merkle tree structure, in the process of renting a corresponding data model, the data model is verified to check whether the called data model is correct or not, and therefore call accuracy is effectively improved.

Description

technical field [0001] The invention relates to a data model verification system and method based on a Merkle tree structure. Background technique [0002] Nowadays, convenient and efficient remote data storage and access services are provided by cloud computing service providers through stable and high-speed network connections. However, due to the characteristics of cloud computing itself, large-scale data storage services face many security risks and challenges; In most cases, data files are divided into several small data blocks for storage, and the geographical location and storage status of each storage block are unknown to the user, so when the user calls the data again, the integrity of the data and the correctness of the data Similarly, when the data model is stored in the server, when the user calls the corresponding data model, the correctness of the calling model must be guaranteed, and the model will not be changed during the calling of the model and the model a...
