【漫画】“格式化”等于彻底删除文件？NO！NO！NO！******

　　万物互联时代，个人隐私信息遭到泄露的原因有很多，但有一种情况很常见却也容易被忽视，那就是电脑重要文件或数据删除不彻底，导致别有用心之人轻易便能恢复。

　　或许有人会说，格式化一下不就可以了吗？

　　也许你不知道，windows系统并不会删除文件，就算清空回收站或格式化，也只是在系统上重新分配它，即文件仍存在于你的系统中，但不再能访问。只要没有其他文件将它覆盖，文件就会完好如初，就可以被很多数据恢复软件恢复。

　　那么，如何彻底删除文件呢？接下来就告诉你，文件擦除是什么，以及它和文件删除之间的区别。

【漫画】“格式化”等于彻底删除文件？NO！NO！NO！

　　文件删除

　　删除文件时，文件会从其现有文件系统的索引位置消失并移动到用户无法访问的另一个文件索引位置。删除的文件移动到新目录后，你的计算机会释放空间来存储新文件。当新文件存储在该空间中时，先前删除的文件将被新文件覆盖并因此被消除。在此之前，可以通过专用的数据恢复软件轻松发现和恢复删除的文件。

　　文件擦除

　　擦除是消除文件，是不可恢复的操作。文件在擦除过程中会被软件写入数据覆盖。其中，包含随机垃圾数据。覆盖可以进行一次或多次，覆盖后，文件变得不可读，这使数据恢复软件无法恢复文件。

　　擦除是一种公认的从硬盘中擦除数据的方法，也是确保硬盘中数据清理的最有效和最全面的方法。

　　为什么文件擦除很重要？

　　如上所述，删除和擦除之间存在根本区别在于删除只是将文件隐藏，而擦除则是完全破坏它，使其无法恢复。

　　当你丢弃/租赁/出售硬盘等存储设备时，擦除就变得十分重要，因为并不希望已删除的数据被恢复。如果只是简单地进行删除或格式化系统处理，将面临严重的隐私问题。这些存储设备的再次拥有者可以随时运行数据恢复软件并恢复敏感数据。

　　由此可见，采用安全的数据清理软件定期擦除敏感数据，不仅是一种良好的数据卫生习惯，也能保护个人隐私信息不被泄露，不让数据泄露成为“隐私之殇”。

中新网评：处理核污水绝不是日本自家私事******

　　中新网北京1月19日电(蒋鲤)日本政府近日称，将于2023年春夏期间开始向海洋排放经过处理的福岛第一核电站核污水。日本罔顾国内民众及周边国家的屡屡反对，企图将核污水“一倒了之”，把一件关乎全球海洋生态环境和公众健康的事当成了自家私事。

　　2011年，福岛核电站事故发生后，大量放射性物质泄漏到大气层和太平洋，对周围环境造成了难以逆转的伤害，数十万人被迫撤离该地区。时至今日，作为日本邻国之一的韩国仍未解除福岛海鲜禁令。

　　日本以核污水存储能力即将达到上限为由，在2021年4月13日，正式决定将福岛第一核电站核污水排入太平洋。过去一年多，日本政府和东京电力公司一直在持续推进核污水排海计划。

　　日本政府辩称，这些核污水经多核素处理系统(ALPS)处理后很安全，甚至“可以喝”，这样的表态无疑在愚弄大众。

　　事实上，经过处理的核污水仍含有多种放射性物质，核污水一旦排放入海就无法回收，长期来看，将会给海洋生态带来难以估量的潜在威胁，最终危害人类健康。

　　因此，核污水排海计划推出后，遭到日本民众强烈反对。日本《朝日新闻》2022年3月公布的问卷调查显示，福岛县、宫城县和岩手县受访的42个市町村长中，约六成反对东京电力公司福岛第一核电站核污水排放入海。日本全国渔业协会联合会也多次申明立场，反对该计划。

　　日本政府认为，核污水排海是最便宜、最省事的解决方案，但此举却将周边国家乃至全世界置于核污染风险中。太平洋非日本一家之海，核污水会随着洋流流动，其影响势必会跨越国界，危害周边国家乃至整个国际社会的公共福祉和利益。

　　《韩国经济新闻》发文称，相关研究认为，福岛核污水如果排放入海，约7个月后将到达济州等韩国海域，该国水产业和旅游业将遭受相当大的损失。

　　德国南极海洋机构也曾发出警告，若日本将所有核污水排入海中，不到半年，整个太平洋都将面临高度辐射威胁，包括远在大洋另一端的美国。太平洋地区人民更是对日本该计划持反对意见。

　　日本作为《联合国海洋法公约》缔约国，有义务保护海洋环境。然而，在核污水排海方案的正当性、核污水数据的可靠性、净化装置的有效性、环境影响的不确定性等问题上，日本未能作出科学、可信的说明。

　　国际原子能机构技术工作组虽已三次赴日实地考察评估，但尚未就日排海方案的安全性给出结论，并且对日本提出诸多澄清要求和整改意见。在此情况下，日本仍执意推进核污水排海工程建设，这是极不负责任的行为。

　　太平洋不是日本的下水道，日本必须正视各方合理关切，在与周边国家等相关利益方和国际原子能机构充分协商后，制定合理的核污水处理方案。日本也要着眼长远，若只顾眼前，执意将核污水排放入海，不仅其自身，周边国家乃至全世界都将为之买单，其后果必将会危害数代人。

　　Fukushima water disposal by no means Japan’s own business

　　By John Lee

　　(ECNS) -- Japan has announced it will release treated wastewater from the wrecked Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean this year.

　　Although Fukushima wastewater disposal affects global marine ecological environment protection and public health, Japan has turned a deaf ear to domestic and international opposition to dumping the contaminated water into the sea, treating the "global" matter as its own business.

　　The Fukushima accident in 2011 had sent large quantities of radiation into the atmosphere and the Pacific Ocean, causing irreversible damage to the surrounding environment, and hundreds of thousands of people were forced to evacuate the area. South Korea still maintains its import ban on Japanese seafood from areas affected by the Fukushima nuclear disaster.

　　On April 13, 2021, Japan announced it had decided to discharge contaminated radioactive wastewater in Fukushima Prefecture into the sea due to dwindling storage space, with the Japanese government and plant operator Tokyo Electric Power Company Holdings Inc. promoting the release plan over the past year.

　　The Japanese government argues that the water treated by an advanced liquid processing system, or ALPS, is safe and drinkable, which is undoubtedly fooling the public.

　　In fact, the treated wastewater still includes a variety of radioactive substances and can’t be recycled once discharged into the sea, which will pose a great threat to marine ecology and ultimately endanger human health in the long run.

　　Therefore, the discharge plan has been strongly opposed in Japan. According to a questionnaire conducted by The Asahi Shimbun, nearly 60 percent of mayors of 42 municipalities in Iwate, Miyagi and Fukushima prefectures oppose the discharge plan. The National Fisheries Cooperative Federation of Japan has also repeatedly stated its opposition in public.

　　The Japanese government believes that dumping Fukushima wastewater into the sea is the cheapest and most convenient solution, but neighboring countries and even the whole world will be at risk of nuclear pollution.

　　The Pacific Ocean doesn’t belong to Japan and the wastewater flow along oceanic currents will surely break boundaries and endanger public welfare and the interests of neighboring countries and even the international community.

　　The Korea Economic Daily reported that related research concluded that if contaminated water from Fukushima is released into the ocean, it would only take seven months for the contaminated water to reach the shores of Jeju Island, with the country's aquaculture and tourism suffering considerable losses.

　　According to the calculation of a German marine scientific research institute, radioactive materials will spread to most of the Pacific Ocean within half a year from the date of discharge, and the U.S. and Canada will be affected by nuclear pollution. People in the Pacific region also oppose the discharge plan.

　　As a participant of the United Nations Convention on the Law of the Sea, Japan has the obligation of protecting the marine environment.

　　However, it hasn’t offered a full and convincing explanation on issues like the legitimacy of the discharge plan, the reliability of data on the nuclear-contaminated water, the efficacy of the treatment system or the uncertainty of environmental impact.

　　Though the IAEA has yet to complete a comprehensive review after three investigations in Japan, the Japanese side has been pushing through the approval process for its discharge plan and even started building facilities for the discharge. It is rather irresponsible for Japan to act against public opinion at home and concerns abroad.

　　The Pacific Ocean is not a private Japanese sewer. The country must seriously heed the voices of the international community and make a reasonable plan for the Fukushima wastewater disposal after full consultation with stakeholders and international agencies.

　　If it only seeks instant interest and insists on discharging the contaminated water into the sea, not only itself, but also its neighboring countries and the entire world will pay for the decision and several generations will be forced to bear the consequence.
