Encrypted query method, system and equipment based on data desensitization sensitive word and medium

The invention relates to the technical field of data security, in particular to an encrypted query method, system and device based on data desensitization sensitive words and a medium. The method comprises the following steps: firstly, establishing a local sensitive word library in a server; secondly, sensitive words in the document to be desensitized are extracted according to a local sensitive word library and marked; then encrypting the marked sensitive words, establishing an encryption index, and uploading the encryption index to a cloud server; and finally, generating a query trap door matched with the encrypted index in the cloud server, and querying the sensitive word to obtain a query result. According to the method, only the sensitive words in the file content are encrypted, so that the loss of original characteristics of the file is avoided, the overall readability of the file is ensured, and the calculation amount of encryption is reduced. 本发明涉及数据安全技术领域，具体地说，涉及一种基于数据脱敏敏感词的加密查询方法、系统、设备及介质；该方法首先在服务器中
