DEVICES, METHODS, AND COMPUTER READABLE MEDIA FOR SCREEN-CAPTURE COMMUNICATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17546149 titled 'DEVICES, METHODS, AND COMPUTER READABLE MEDIA FOR SCREEN-CAPTURE COMMUNICATION
Simplified Explanation
The present disclosure describes a method, apparatus, and computer readable media for screen-capture communication using invisible watermarks. The method involves inserting templates into video frames to correct frame perspective, writing a message into the frames, and displaying the video. Another method involves capturing frames of a video with a hidden message, locating templates to correct frame perspective, and extracting the message from the frames.
- The technology enables screen-capture communication using invisible watermarks.
- Templates are inserted into video frames to correct frame perspective.
- Messages can be written into the frames and displayed in the video.
- Frames with hidden messages can be captured from a video displayed on a device.
- Templates are used to correct the frame perspective of the captured frames.
- The hidden message can then be extracted from the frames.
Potential Applications
- Secure communication: This technology can be used for secure communication by embedding hidden messages in videos, ensuring only intended recipients can extract and decode the messages.
- Digital watermarking: The invisible watermarking technique can be applied to protect copyrighted content by embedding watermarks that can be used to identify the source or owner of the content.
- Video editing and correction: The use of templates to correct frame perspective can be beneficial in video editing and correction processes, ensuring accurate and visually appealing results.
Problems Solved
- Secure communication: The technology solves the problem of secure communication by providing a method to embed hidden messages in videos, making it difficult for unauthorized individuals to intercept or understand the messages.
- Copyright protection: By embedding invisible watermarks, the technology helps protect copyrighted content from unauthorized use or distribution, as the watermarks can be used to identify the source or owner of the content.
- Frame perspective correction: The use of templates to correct frame perspective solves the problem of distorted or skewed frames in videos, resulting in improved visual quality and accuracy.
Benefits
- Enhanced security: The invisible watermarking technique adds an extra layer of security to communication, ensuring that messages remain confidential and can only be accessed by authorized recipients.
- Copyright protection: The embedded watermarks help deter unauthorized use or distribution of copyrighted content, providing a means to identify and track the source or owner of the content.
- Improved video quality: The correction of frame perspective using templates improves the visual quality and accuracy of videos, resulting in a more professional and visually appealing output.
Original Abstract Submitted
The present disclosure provides for methods, apparatus and computer readable media related to screen-capture communication based on invisible watermark. An aspect of the disclosure provides for a method including inserting one or more templates into one or more frames of a video for correcting frame perspective of the one or more frames captured by a device. The method further includes writing a message into the one or more frames of the video and displaying the video. According to a second aspect, a second method is provided. The second method includes capturing one or more frames of a video displayed on a device comprising a hidden message. The method further includes locating one or more templates and correcting frame perspective of the captured frames based on the templates. The method further includes extracting the message from the one or more frames of the video.
