Problems solved by technology

[0005] On-demand transformation of the database will increase more research and development costs and time, and may damage the original functions provided by the database. For example, the retrieval effect after transformation is worse than that before transformation.

Abstract

The invention provides an encrypted data processing method and device and equipment, and relates to the field of information security or financial science and technology. The encrypted data processing method comprises the steps of calling a text analysis interface of a first database to process a first retrieval text to obtain a first segmented word set, wherein encrypted data is stored in the first database; encrypting at least one element in the first word segmentation set based on a first encryption algorithm to obtain a second word segmentation set; processing the second segmented word set to obtain a second retrieval text; and sending the second retrieval text to the first database, so that the first database calls the text analysis interface to process the second retrieval text to retrieve the encrypted data. The invention further provides another encrypted data processing method and device and equipment.

Description

technical field [0001] The present disclosure relates to the field of information security or the field of financial technology, etc., and more specifically relates to an encrypted data processing method, device and electronic equipment. Background technique [0002] Units or individuals generate a large amount of data in the process of production and life, usually through the database to store the data, when some data needs to be used, search and query in the database. For sensitive data that does not want to be leaked, it will be encrypted and stored, but the encrypted data may not be retrieved directly through the database. [0003] Usually, the database can be modified, such as adding functions such as encryption, decryption, or ciphertext retrieval on the basis of the source code of the database. The transformed database can provide storage and retrieval functions of encrypted data. [0004] In the process of realizing the concept of the present disclosure, the invent...
