摘要:
The present invention provides a system, method, and computer-readable medium for quarantining a file. Embodiments of the present invention are included in antivirus software that maintains a user interface. From the user interface, a user may issue a command to quarantine a file or the quarantine process may be initiated automatically by the antivirus software after malware is identified. When a file is marked for quarantine, aspects of the present invention encode file data with a function that is reversible. Then a set of metadata is identified that describes attributes of the file including any heightened security features that are used to limit access to the file. The metadata is moved to a quarantine folder, while the encoded file remains at the same location in the file system. As a result, the encoded file maintains the same file attributes as the original, non-quarantined file, including any heightened security features.
摘要:
In a network multimedia conference, a bridge service that functions as a proxy for a client to join the conference dynamically selects a video stream from multiple video streams originating from the other participants of the conference and sends the selected video stream to the client for viewing. The bridge service monitors conferencing events of each participant and updates conferencing activity state variables of the participant, such as whether the participant is being shown to the client, whether the participant is talking, how long the participant has been shown or not shown, etc. Periodically, a weight assigned to each of the participants is computed based on the state variables, and the video stream of the participant with the highest weight is then selected for viewing by the client.
