AI Technical Summary
Technical Problem
In existing technologies, the modifiability of the system clock means that files under WORM protection status may be tampered with after the protection period expires, thus failing to effectively prevent data tampering.
Method used
By creating a timing file in the file system to record the duration of the WORM protection state, and canceling the WORM protection state when the duration recorded in the timing file exceeds the maximum protection duration, a timing mechanism independent of the system time is used to prevent tampering.
Benefits of technology
It effectively prevents files from being compromised by tampering with the system time, ensuring the security and integrity of data within a specified time.

Abstract
本发明实施例提供一种文件计时方法及装置，在本发明实施例中，针对被设置为WORM保护状态的目标文件，创建对应的计时文件记录WORM保护状态时长，其中，该计时文件的第一数据定时更新，在通过该第一数据确定的计时文件创建时长大于最大WORM保护状态时长时，取消该目标文件的WORM保护状态。这解决了采用系统时间作为文件WORM保护状态的基准时间时，可以通过篡改系统时间使WORM保护状态的文件在WORM保护时间内被破坏的问题。
