We have developed this technology. Our technology works on regular pen drives that are available in the market, there is no need for custom manufactured pen drives. Technology defends video lectures from copying, ripping, file sharing, screen capture etc. Lectures play only from the original pen drive. Technology has many other features like expiry date, limit on the number of times a video lecture can be played, superimposition of serial number on video etc. We have many existing customers using our technology to sell protected video lectures, with thousands of pen drive already sold in the market using out technology. Please reply back for further discussion and demos. Lastly and not the least, you do not need to share any content with us, all pen drive burning will happen at your premises. Please ignore quote.
