TLDR
Different levels of security are provided in a security system so that users can decide the security level of their own communications Users can choose a low level of security and maintain the security overhead as low as possible Alternatively, they can choose higher levels with attendant increases in security overhead as discussed by the authors.Abstract:
Different levels of security are provided in a security system so that users can decide the security level of their own communications Users can choose a low level of security and maintain the security overhead as low as possible Alternatively, they can choose higher levels of security with attendant increases in security overhead The different levels of security are created by the use of one or more of two keys: an encryption key is used to encrypt plaintext data in a delta and a message authentication key is used to authenticate and insure integrity of the data Two keys are used to avoid re-encrypting the encrypted data for each member of the telespace In one embodiment, the security level is determined when a telespace is created and remains fixed through out the life of the telespace For a telespace, the security level may range from no security at all to security between the members of the telespace and outsiders to security between pairs of members of the telespace In another embodiment, subgroups called “tribes” can be formed within a telespace and each tribe adopts the security level of the telespace in which it resides METHOD AND APPARATUS FOR MANAGING SECURE COLLABORATIVE TRANSACTIONSread more

Desktop application for access and interaction with workspaces in a cloud-based content management system and synchronization mechanisms thereof
TL;DR: In this paper, the system and methods for synchronizing workspaces in a web-based collaboration environment with local folders on computers of collaborators of the workspaces are disclosed, and conflicts between edits made by different collaborators to the same file are flagged and a notification is sent to the author attempting to make edits to a version of a file that has already been updated by another collaborator.
Patent
Real time notification of activities that occur in a web-based collaboration environment
TL;DR: In this article, a real-time notification system for activities that occur in a web-based collaboration environment is described. But the method of selecting a recipient of a notification according to criteria determined based on a workspace in which the activity was performed in the online collaboration platform and/or sending the notification of the activity to the recipient such that the recipient is notified in real time or near real time to when the activity occurred.

Patent
Cloud service enabled to handle a set of files depicted to a user as a single file in a native operating system
TL;DR: In this paper, the authors present a method for representing the folder structure in a user interface to a cloud-based service as a file and enabling file actions to be performed on the file.
Patent
Repository redundancy implementation of a system which incrementally updates clients with events that occurred via a cloud-enabled platform
TL;DR: In this article, techniques for implementing repository redundancy in a system which incrementally updates remote clients with events that occurred in a cloud-enabled platform are presented, where the event is to be stored in a queue in a repository cluster to be read by a remote client.
