Springer strongly believes that the value of content is maximized if usage restrictions are kept to a minimum. Therefore Springer eBooks do not employ hard Digital Right Management (DRM). Instead our eBooks are individually watermarked outside of the text area, causing no limitation to the usability of the file. There is also an invisible watermark. The main benefit is that Springer eBooks can be used on all reading devices.
This liberal policy increases the risk of piracy, but Springer’s philosophy is that this side effect does not outweigh the benefits. To protect our authors’ rights, Springer invests in and uses effective methods and state-of-the art technology to detect, stop, and prosecute illegal sharing. For more information see here.
