AI Technical Summary

Technical Problem

In situations where multiple parties share data, how can we securely store and retrieve data outside the domain, avoiding storage pressure and the risk of data leakage, while protecting data privacy and the security of query conditions?

Method used

The data identifier is encrypted using a local private key to generate identifier ciphertext. The identifier ciphertext is then used to encrypt the data to be stored on an external storage platform. At the same time, a decryption key is obtained through secure interaction to decrypt the data, ensuring the security of the data on the external storage platform and the reliability of the query.

Benefits of technology

It enables secure storage and retrieval of data on external storage platforms, protecting data privacy and the security of query conditions, reducing storage and access pressure, and improving the efficiency of data retrieval.

Abstract

本说明书实施例提供一种数据存储、查询的方法及装置,用于协作的多个业务方共享数据的情况下,在数据的存储方和查询方不一致时,实现保护查询方隐私的隐私保护查询。具体而言,由存储方基于协商一致的数据标识构建对称加密密钥,将数据加密后存储在外部存储平台,查询方通过外部存储平台查询数据时,可以基于协商一致的数据标识获取数据密文,并经由与存储方的安全交互,构建解密密钥,从而解密从外部存储平台获取的数据密文,得到待查询数据。该技术构思可以在有效保护数据隐私的基础上提高查询效率。
