One such project, RAPPOR (Randomized Aggregatable Privacy-Preserving Ordinal Response), provides a new state-of-the-art, privacy-preserving way to learn software statistics that we can use to better safeguard our users’ security, find bugs, and improve the overall user experience.<br /> <br /> Building on the concept of <a href="http://en.wikipedia.org/wiki/Randomized_response">randomized response</a>, RAPPOR enables learning statistics about the behavior of users’ software while guaranteeing client privacy. The guarantees of <a href="http://en.wikipedia.org/wiki/Differential_privacy">differential privacy</a>, which are widely accepted as being the <a href="http://arxiv.org/abs/1402.3329">strongest form of privacy</a>, have almost never been used in practice despite <a href="https://www.youtube.com/watch?v=Gx13lgEudtU">intense research in academia</a>.  RAPPOR introduces a practical method to achieve those guarantees.<br /> <br /> To understand RAPPOR, consider the following example. Let’s say you wanted to count how many of your online friends were dogs, while respecting the maxim that, <a href="http://en.wikipedia.org/wiki/On_the_Internet,_nobody_knows_you%27re_a_dog">on the Internet, nobody should know you’re a dog</a>. To do this, you could ask each friend to answer the question “Are you a dog?” in the following way. Each friend should flip a coin in secret, and answer the question truthfully if the coin came up heads; but, if the coin came up tails, that friend should always say “Yes” regardless. Then you could get a good estimate of the true count from the greater-than-half fraction of your friends that answered “Yes”. However, you still wouldn’t know which of your friends was a dog: each answer “Yes” would most likely be due to that friend’s coin flip coming up tails.<br /> <br /> RAPPOR builds on the above concept, allowing software to send reports that are effectively indistinguishable from the results of random coin flips and are free of any unique identifiers. However, by aggregating the reports we can learn the common statistics that are shared by many users. We’re currently testing the use of RAPPOR in Chrome, to learn statistics about how <a href="//www.google.com/about/company/unwanted-software-policy.html">unwanted software</a> is <a href="http://chrome.blogspot.com/2013/10/dont-mess-with-my-browser.html">hijacking</a> users’ settings.<br /> <br /> We believe that RAPPOR has the potential to be applied for a number of different purposes, so we're making it freely available for all to use. We'll continue development of RAPPOR as a standalone <a href="https://github.com/google/rappor">open-source project</a> so that anybody can inspect and test its reporting and analysis mechanisms, and help develop the technology. We’ve written up the technical details of RAPPOR in a <a href="http://arxiv.org/abs/1407.6981">report</a> that will be published next week at the <a href="http://www.sigsac.org/ccs/CCS2014/">ACM Conference on Computer and Communications Security</a>.<br /> <br /> We’re encouraged by the <a href="https://cdt.org/blog/having-your-big-data-cake-and-eating-it-too/">feedback</a> we’ve received so far from academics and other stakeholders, and we’re looking forward to additional comments from the community.

To support that, Noto is available in different subsets including Japanese, Korean, Simplified Chinese, Traditional Chinese, and all of CJK. Developers can then use CSS's font fallback mechanism to specify a LGC font ahead of a Noto Sans subset.<br /> <br /> For example, if you're targeting devices that don't have Noto installed, want to use Arial for LGC characters, and want to use Noto for Japanese characters, you can include the following in your stylesheet:<br /> <blockquote> <span style="font-family: Courier New, Courier, monospace;">@import url(http://fonts.googleapis.com/earlyaccess/notosansjapanese.css);</span> </blockquote> <blockquote>  <span style="font-family: 'Courier New', Courier, monospace;">body {</span></blockquote> <blockquote> <blockquote> <span style="font-family: Courier New, Courier, monospace;">font-family: Arial, 'Noto Sans Japanese', sans-serif;</span></blockquote> <span style="font-family: Courier New, Courier, monospace;">}</span></blockquote> Shipping Noto by default on ChromeOS is one step towards making “tofu” a thing of the past.
