HTML5 standard Save big flaw: battery information can be leaked online activities-HTML5-IT information

IT news , August 3, because of the large safety hazard and the rise of HTML5, Flash is almost cornered, has now said, HTML5 also has a huge flaw, its battery information leaked to the Web site through the mobile phone user's Internet activity.

It is understood that the new functionality added in HTML5, the percentage of battery charge, time, charge time, and other information are likely to be used by Web developers. Now, a team of researchers at Princeton University confirmed the vulnerability.

The researchers found, write this code using HTML5 on battery function to track user Internet activity can be achieved. With this defect, these sites can publish targeted ads to the user, even through a built-in feature to track a user's browsing history of the browser.

Now researchers have reported this defect to the W3C HTML5 standards bodies, but it is not clear how W3C will fix this vulnerability.

HTML5标准存大缺陷：手机电池信息可泄露上网活动 - HTML5 - IT资讯

IT资讯8月3日消息，由于安全隐患巨大以及HTML5的兴起，Flash几乎被逼入绝境，现在有眼称，HTML5标准也存在巨大缺陷，其可能通过手机电池信息向网站泄露用户的上网活动。

据了解，在HTML5添加的新功能中，有关电池电量百分比、使用时间、充电时间等信息都有可能被网站开发人员使用。现在，来自普林斯顿大学的一个研究团队就证实了其中的漏洞。

研究人员发现，利用HTML5种有关电池的功能编写相关代码可实现对用户上网活动的追踪。借助该缺陷，这些网站能向用户发布更有针对性的广告，甚至能通过浏览器的一个内置特性追踪用户的浏览历史。

目前研究人员已经向HTML5标准机构W3C报告了这一缺陷，但尚不清楚W3C将如何修复这一漏洞。
