Infosys invents watermarking methods for copyright protection

On the one hand, digital technology simplifies content production, distribution and monetization. On the other, it attracts piracy and unauthorized distribution. Unlawful reproduction / copying and distribution can be prevented by incorporating copyright information into digital content.

The Infosys Media and Entertainment practice generated watermarking algorithms for secure distribution of digital content. Our watermarks can be embedded in pixels, a selected spectral frequency band, or in each scene of video content, based on the requirements of the content owner. The United States Patent and Trademark Office (USPTO) has granted patents for our digital watermarking methods for copyright and digital rights protection.

Our algorithms embed a pre-processed watermark into a video in real time, either during capture or while delivering / streaming. It can also be used to extract the watermark from the original or a copy of stored video files. Significantly, our robust pixel watermarking system addresses the issues of interoperability and mobility in digital media.

Infosys’ system for transcoding-resistant watermarking enhances data security across multimedia formats, and rationalizes processing overheads as well as computational complexity and cost. It inserts the watermark pattern in a spectral frequency band in the original media content while mitigating risks of transcoding for diverse devices.

Our technique for watermarking each scene in frames safeguards original content from tampering and breaches during image processing. It uses visual cryptography for optimizing watermarking and detecting copyright infringement. Digital signing and time stamping help verify the watermark pattern to confirm ownership of content.
