What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12585816B2, covering systems and methods for selective encryption of sensitive image data within video streams. The invention allows for the encryption of only sensitive image data regions within video frames, while compressing less sensitive data without encryption. This approach aims to mitigate the performance and resource overhead typically associated with encrypting entire video streams.

This patent grant is primarily relevant to technology companies involved in video streaming, data security, and compression technologies. While patents themselves do not impose direct compliance obligations on other entities, they establish intellectual property rights that could impact product development and market entry. Companies operating in this space should be aware of this patented technology to avoid potential infringement issues.

Abstract

Disclosed is a selective encryption system that selectively encrypts sensitive image data within frames of a video stream and compresses other insensitive image data within the frames in order to generate and distribute a partially encrypted video stream that protects the sensitive image data without the time, energy, resource, and size penalty associated with encrypting all image data in all frames of the video stream. The system parses a video stream image into different regions that each contain different image data. The system detects first regions that contain the sensitive image data, encrypts the sensitive image data in the first regions, and compresses the image data in other second regions without encryption. The system distributes a selectively encrypted frame of the video stream that includes the encrypted image data for the first regions and the compressed image data for second regions.
