END-TO-END WATERMARKING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18027418 titled 'END-TO-END WATERMARKING SYSTEM

Simplified Explanation

The patent application describes methods, systems, and apparatus for generating and decoding watermarks. Here is a simplified explanation of the abstract:

  • An image and a data item are received.
  • A first watermark is generated by the encoder.
  • A second watermark is generated using multiple first watermarks.
  • The second watermark is overlaid on the image to watermark it.
  • Presence of a watermark is determined on a portion of the image for decoding.
  • A distortion model predicts distortions in the image and modifies the portion based on the predicted distortions.
  • The modified portion is decoded to obtain a predicted first data item for validating the watermark.

Potential Applications

The technology described in this patent application could be applied in various fields such as digital rights management, authentication, and copyright protection.

Problems Solved

This technology solves the problem of securely embedding and decoding watermarks in digital images to protect intellectual property and verify authenticity.

Benefits

The benefits of this technology include enhanced security for digital content, improved copyright protection, and reliable authentication of images.

Potential Commercial Applications

The technology could be commercially applied in industries such as photography, publishing, digital media, and online content distribution under the title "Commercial Applications of Watermark Generation and Decoding Technology."

Possible Prior Art

One possible prior art for this technology could be existing watermarking techniques used in digital media and copyright protection.

Unanswered Questions

How does the distortion model accurately predict distortions in the image for modifying the portion during decoding?

The distortion model likely uses algorithms and mathematical calculations to analyze the image data and predict distortions based on known factors such as compression artifacts or noise.

What are the specific criteria used to validate the watermark based on the predicted first data item?

The validation process likely involves comparing the predicted first data item with the original data item embedded in the watermark to confirm the authenticity and integrity of the watermark.


Original Abstract Submitted

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating and decoding watermarks. An image and a data item is received. The encoder generates a first watermark and then a second watermark is generated using multiple first watermarks. The second watermark is used to watermark the image by overlaying the second watermark over the image. To decode the watermark, presence of a watermark is determined on a portion of an image. A distortion model determines distortions in the image and modifies the portion of the image based on the predicted distortions. The modified portion is decoded using the decoder to obtain a predicted first data item that is further used to validate the watermark based on the first data item.
