Abstract

A host server information handling system executing a multimedia multi-user collaboration application (MMCA) may include a processor; a memory; a power management unit; a network interface device to receive and provide audio/visual (AV) data during execution of the MMCA for a video conference session; the processor configured to execute a collaborative rights information management system to: manage the recordation of a video conference session during the execution of the MMCA to create a recording of the video conference session and assign a first password to protect the recording of the video conference session as a default password; assign a security level to the recording of the video conference session; and permit access, via the network interface device, to the recordings of the video conference session by transmitting the password to those users who are associated with a higher user access permission level than the aggregated user access permissions and are authorized to access the recording.

First claim

What is claimed is:

1. A host server information handling system executing a multimedia multi-user collaboration application (MMCA), comprising:
a processor;
a memory;
a power management unit;
a network interface device to receive and provide audio/visual (AV) data during execution of the MMCA for a video conference session;
the processor configured to execute a collaborative rights information management system to:
manage a recording of the video conference session during the execution of the MMCA to create the recording of the video conference session and assign a first password to protect the recording of the video conference session as a default password;
monitor and aggregate user identification data and access permissions associated with each user accessing the video conference session during the execution of the MMCA;
monitor each user's sign-in and sign-out times with the user's identification data during the video conference session;
determine changes to aggregated user access permissions associated with each user accessing the video conference session to include user identifications of users having lower user access permission level than is allowed to view the recording;
assign a security level to the recording of the video conference session;
generate a second password to replace the first password to protect the recording of the video conference session based on the changes to the aggregated user access permissions associated with each user accessing the video conference session to exclude the user identifications of users having the lower user access permission level; and
permit access, via the network interface device, to the recordings of the video conference session by transmitting the second password to those user identifications of users who are associated with a higher user access permission level than the aggregated user access permissions and are authorized to access the recording.

2. The information handling system of claim 1 further comprising:
the collaborative rights information management system separating the recording of the video conference session into a plurality of AV video conference segment session files based on each user's sign-in and sign-out times during the video conference session; and
the collaborative rights information management system, via the network interface device, transmitting the second password and decryption data for accessing the whole recording when a first AV video conference segment session file has a security level that requires the user with higher access permission level.

3. The information handling system of claim 1 further comprising:
a rights information management user access permission database to store user access permissions associated with each user identification of a user on a rights information management user access permission database, the user access permissions stored on the rights information management user access permission database defining an access level to the recordings of the video conference session based on the user identification of an email address.

4. The information handling system of claim 1 further comprising:
the collaborative rights information management system separating the recording of the video conference session into a plurality of AV video conference segment session files based on each user's sign-in and sign-out times during the video conference session, the collaborative rights information management system configured to:
assign different security levels to the plurality of AV video conference segment session files; and
encrypt the plurality of AV video conference session files in the same video container allowing each user with access permission levels meeting the security levels of corresponding AV video conference segment session files to access those corresponding plurality of AV video conference segment session files via one or more decryption keys.

5. The information handling system of claim 1 , wherein the user access permission levels associated with each user are based on content data retained from an enterprise directory describing the positions held by each user within the enterprise and a tiered user access permission associated with the positions.

6. The information handling system of claim 1 further comprising:
the processor executing the collaborative rights information management system to allow access to a user without any assigned security levels to the video conference session and decryption assigning that user without any assigned security levels a default user access permission level, the default user access permission level limiting access to the recording of the video conference session.

7. A method of managing recordings during a video conference session, comprising:
managing the recordation of the video conference session during the execution of the MMCA, via a processor, to create a recording of the video conference session and assign a first password to protect the recording of the video conference session as a default password;
monitoring and aggregating, with the processor, user identification data and access permissions associated with each user accessing the video conference session during the execution of the MMCA;
monitoring each user's sign-in and sign-out times with the user's identification data during the video conference session;
monitoring content presented during the video conference session for security-enhancing stimuli from the context of the videoconference session;
setting a security level associated with the recording of the video conference session based on a detected security-enhancing stimulus;
determining user access permissions associated with each user accessing the video conference session to include user identifications of users having lower user access permission level than meets the designation security level to view the recording;
generating a second password to replace the first password to protect the recording of the video conference session based on the user access permissions associated with each user accessing the video conference session to exclude the user identifications having the lower user access permission level; and
permitting access, via the network interface device, to the recordings of the video conference session by transmitting the second password to those user identifications of users who are associated with a higher user access permission level than meets the designated security level and are authorized to access the recording.

8. The method of claim 7 further comprising:
with the execution of the collaborative rights information management system by the processor, separating the recording of the video conference session into a plurality of AV video conference segment session files based on each user's sign-in and sign-out times during the video conference session and the access permission of the user identification for that user; and
the collaborative rights information management system, via the network interface device, transmitting the second password for accessing the whole recording when a first AV video conference segment session file has a security level that requires the user with higher access permission level.

9. The method of claim 7 further comprising:
with the execution of the collaborative rights information management system by the processor, separating the recording of the video conference session into a plurality of AV video conference segment session files based on when the security-enhancing stimuli is detected, the security-enhancing stimuli including the detection of the presentation of a proprietary document; and
the collaborative rights information management system, via the network interface de
