10,621,315, "Event-driven generation of watermarked previews of an object in a collaboration environment," assigned to Box, Inc.
Systems for dynamic watermarking within a cloud-based collaboration environment. Storage facilities are managed by servers to provide cloud-based storage services to two or more client entities as a service across a network. The servers maintain versions of editable documents or photo images or video clips using a version indication. Dynamic watermarking applies a first watermark image to a first version of the editable document and grants edit access to a first client entity of the two or more client entities. While the first client entity has edit access to the first version of the editable document the system generates a second version of the editable document and applies a second watermark image to the second version of the editable document before delivering the second version to a second client entity. A security watermark is based on a user credential, and a leak source can be determined based the user credential.

The present disclosure describes systems and methods for generating and utilizing contextual watermarks. In accordance with an embodiment the method includes: receiving reference sensor data characterizing a proprietary event; receiving a plurality of media streams for potential distribution, each media stream including respective embedded contextual sensor data; for each stream, comparing the reference sensor data with the respective embedded contextual sensor data to identify streams generated at the proprietary event; and distributing only those media streams that are not identified as being generated at the proprietary event.
