A file desensitization method and apparatus, and a storage medium. The method is performed by a storage device, and the method comprises: receiving a file reading command sent by a host, the file reading command being used for requesting a file to be read (S11); in response to the file reading command, obtaining the file to be read, at least a portion of data blocks in the file to be read having been desensitized (S12); desensitizing the data blocks in the file to be read which have not been desensitized (S13); and sending, to the host, the desensitized file to be read (S14).
