New study: mobile screens can also "expose" your privacy-IT information
According to the "ZEM science" website reported that researchers at the University of California, San Diego School of medicine have recently published called ' mobile lives for personal analysis chemistry papers, published in the United States National Academy of Sciences journal. Article said that as long as the analysis of mobile phone screens, will be able to know the consumer's lifestyle.
When people touch a thing, we leave traces, imagine a greasy table glass or covered with fingerprints. Mobile phones are the most tangible in people's daily, through the analysis of chemical molecules on the cell phone screen to restore a person's lifestyle, including diet, health status, health supplies and the places they visit.
Mobile phone users have been participating in the experiment were asked does not use any personal care product in three days, but they still can collect on the phone screen to anti-inflammatory drugs, anti-fungal creams, hair loss prevention solution, antidepressants, eye drops, all kinds of internal and external service thing. They are basically the user home. Like citrus, caffeine, herbs and spices, such as common food molecules can be detected, even a few months ago using insect repellents can also be detected.
Bide·daorui Austin, a Professor of medicine believe that people all chemicals can leave traces in the body, it can be inferred from chemical traces on the everyday lifestyle of a person. Molecules on the phone can tell scientists, owner of daily life is like. For example, you can determine the user is female or male, uses high-end cosmetics, hair dyes, like coffee or wine, loves spicy food, whether it is for treatment of depression, daily cleaning which sunscreen, like outdoor activities. All information can be used to narrow the search range of cell phone users.
The researchers said this new method for mass spectrometry analysis of chemical traces of potential use of broad, especially in the field of criminal investigation. Imagine being at the crime scene, police found a private phone, however it did not leave any fingerprints or DNA information, cannot find corresponding records in the database, and therefore was unable to find the owner of the goods, nor administer justice. But with this new method, determine the range of targets is not so difficult.
The team preparing for larger-scale experiments, molecular mass spectrometry method to other items, such as wallets and keys. Technologies mature, are expected to be used in medicine, environmental studies, airport security or clinical monitoring of compliance. Doctors can know if patients stay on prescription medication or skin from metabolic analysis in patients who are exposed to harmful substances.

手机屏幕也能“暴露”你的隐私 - IT资讯
据“ZEM科学”网站报道，加州圣地亚哥大学医药学学院的研究者们近日发表名为《针对个人分析的手机生活化学》的论文，刊登于美国国家科学学院院刊。文章称，只要分析一下手机屏，就能知道使用者的生活方式。
每当人们摸过一个东西，都会留下分子痕迹，想象一下油腻腻的餐桌或粘满指纹的玻璃杯。手机是人们日常中摸得最多的东西，通过分析手机屏幕上的化学分子能够大致还原一个人的生活方式，包括饮食、健康状况、常用卫生用品以及去过的地方。
参与实验的手机用户已被要求在三天内不使用任何个人护理产品，但研究者依然可以在手机屏上采集到抗炎药、抗真菌乳膏、防脱发药水、抗抑郁药、眼药水、各种内外服的东西。它们基本上都是用户日常用的。像柑橘、咖啡因、草药和香料等常见的食物分子也能检测出来，甚至几个月前使用的驱虫剂也能被查出。
医药学教授彼得·道瑞斯汀认为，人们身上所有的化学物质都能在物体上留下痕迹，因此可以根据日常用品上的化学痕迹推断一个人的生活方式。手机上的分子基本能告诉科学家，主人的日常生活是怎样的。比如，可以判断用户是女性还是男性，是否使用高端彩妆、染发、喜欢喝咖啡还是红酒、是否爱吃辣、是否正在治疗抑郁症、日常擦哪种防晒霜、是否喜欢户外活动等。所有的信息都能被用来缩小搜查手机用户的范围。
研究者们表示，这种对物品化学痕迹进行质谱分析的新方法潜在用途广阔，尤其在犯罪调查领域。想象一下，在犯罪现场，警察只找到一部私人手机，然而它上面却没有留下任何指纹或DNA信息，无法在数据库中找到对应记录，因此无法找到物品的所有者，也无法断案。但有了这个新方法，确定目标人物的范围就不那么困难了。
该团队预备进行更大规模的调查实验，将分子质谱分析的方法应用到其它生活物品中去，比如钱包和钥匙等。技术成熟后，有望被应用于医药学、环境研究、机场安检或临床依从性监测等方面。医生可以及时知晓病人是否按处方服药或从皮肤代谢中分析出患者是否接触过有害物质等。
