Instead of providing a font file directly to clients, we provide a block of dynamically-generated CSS code for use on the client’s site. The actual font file is hosted on our secure servers, and its URL is not visible to the end user. Furthermore, the fonts are subsetted, using only the characters required by the specific website, which makes downloading of the fonts very fast. And since about 95% of the font information is removed, even if the file is pirated it only contains 5% of the font software.
Additionally, specific font tables that are required for normal use of the fonts are removed, which makes the webfonts unusable in standard computer applications. Finally, all fonts carry a digital watermark which enables tracing of unauthorised users.
