In fact, although it is simple and common to use Windows to share and manage files, there are obvious flaws:
2.As long as there is a read-only permission to share, the file can be copied, which cannot achieve this security need - "only authorize the user to use (browse, modify, etc.) the shared file, but it is not allowed to copy, save and take away the file";
I've been looking for a solution online for several years, and I've seen countless people like me looking for a solution, but I haven't been able to find it. Even many people think this idea is ridiculous:"Since you can browse and share files, how can you prohibit the **, copying, and saving of files? "
Later, I made a software that implements the above functions for sharing (safeshare
The latest version is the latest version), in which I have obtained a patent for the invention of the security technology I used (not a high-risk method of encrypting files). I'm very proud of that. Here is an introduction for you to try, I hope to give more comments to help me continue to improve.
