Example Embodiment

[0109] To enable those skilled in the art to better understand the technical solution of the present invention, the ciphertext data query method, device and ciphertext query server provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0110] figure 1 This is a flowchart of a method for querying ciphertext data provided in the first embodiment of the present invention, such as figure 1 As shown, the method includes:

[0111] Step 101: The data management client performs security configuration on the plaintext data to generate a first configuration file. The plaintext data includes a plurality of plaintext information, and the plurality of plaintext information includes data identification information, user identification information, and data content information. The first configuration file includes the sensitivity level of each plaintext information.

[0112] In this embodiment, each plaintext data may be a plaintext dat...

Abstract

The invention discloses a ciphertext data query method, a ciphertext data query device and a ciphertext query server. The ciphertext data query method comprises the steps of: receiving a data query request sent by a user client, wherein the data query request comprises a user identifier ciphertext; sending a ciphertext data request to a ciphertext database, wherein the ciphertext data request comprises the user identifier ciphertext, so that target ciphertext data comprising the user identifier ciphertext can be queried from stored ciphertext data in the ciphertext database; receiving the target ciphertext data sent by the ciphertext database, wherein the target ciphertext data comprises a target data identifier ciphertext, a target user identifier ciphertext and a target data content ciphertext; and sending the target ciphertext data to the user client. The ciphertext data query method, the ciphertext data query device and the ciphertext query server provided by the invention ensure the privacy and security of user data.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a ciphertext data query method, device and ciphertext query server. Background technique [0002] The electronic medical record system can conveniently save, manage, transmit and reproduce digital medical records, replace handwritten paper medical records, and provide users with complete and accurate medical data. Through the medical data in the electronic medical system, doctors can completely electronically process most of the business data, users can conveniently query medical records, and third-party research institutions can conveniently conduct statistical research on data. Therefore, the medical data stored in the electronic medical record system can serve all parties well, while reducing the management costs of all parties. The electronic medical record system contains a large amount of personal privacy data. Therefore, once the electronic medical record system is expos...
