In the scenario of internal business meeting or training, we might need to share some files like the presentation to participants by the invitation email or an online meeting system. For saving the space and version control, we usually copy&paste the file link generated by a web storage system other than uploading the original files again. While the web storage system usually has its own authentication mechanism, the participants of that meeting might not have the permission to download those files. This disclosure provide an easy access control method for these temporary meeting attachments.
