Abstract

The invention discloses a file directory management method based on a Merkle DAG. When the sub-directory node of the first directory node in the existing directory tree is modified, not directly modifying the existing directory tree, but determining a first modification result of the modification, and determining a second modification result obtained by modifying all ancestor directory nodes of the sub-directory node along with the modification of the sub-directory node. The first modification result and the second modification result are added on the basis of the existing directory tree, so that the directory tree can record the result after each modification, historical modification content of each modification can be traced conveniently, and recovery of the directory tree is facilitated. The invention further provides a directory tree management device and system and a computer readable storage medium which can also achieve the effects.

Description

technical field [0001] The present invention relates to the technical field of directory trees, in particular to a Merkle DAG-based file directory tree management method, device, system and a computer-readable storage medium. Background technique [0002] In a computer system, a directory tree is usually used to manage files stored in each layer path. In the directory tree, the parent directory stores pointers to subdirectories, and the subdirectory can be found through the parent directory. However, in the current directory tree technology, if the directory tree is maliciously tampered with, it is difficult to restore the structure before the tampering. [0003] Therefore, how to restore the structure of the directory tree conveniently is a problem to be solved by those skilled in the art. Contents of the invention [0004] The object of the present invention is to provide a Merkle DAG-based file directory tree management method, device, system and a computer-readable st...
