Privacy vs Security
The difference between privacy and security can be a bit confusing as security and privacy are two interrelated terms. In information technology world, providing security means providing three security services:confidentiality,integrity和可用性。其中一个的机密性或隐私。因此,隐私只是安全的一部分。隐私或机密性意味着只有预定的当事方知道秘密的地方。提供机密性最常用的技术是encryption。To provide other security services techniques such ashash功能,firewallsare used.
What is Security?
关于信息技术的安全一词是指提供三个安全服务机密性,完整性和可用性。机密性正在隐藏未经授权的各方的信息。诚信意味着防止对数据的任何未经授权的篡改或修改。可用性意味着为授权方提供服务而不会受到干扰。攻击者在攻击者中窃取了一个人向另一个人发送的信息,造成了机密性的威胁。诸如加密之类的技术用于针对此类攻击提供安全性。在加密中,原始消息基于钥匙and without the key an attacker won’t be able to read the message. Only the intended parties are given the key using a secure channel so that they can only read.AES, DES, RSA and Blowfish are some most famous encryptionalgorithms在那里。
Attacks like modification, masquerading, replaying, and repudiation are some attacks that threaten integrity. For example, say someone sends an online request to a bank and someone taps the message on the way, modifies it and sends to the bank. A technique called hashing is used to provide security against such attacks. Here a hash value is calculated based on the content of the message using a hashing algorithm like MD5 or SHA and sent with the message. If someone does even a tiny modification to the original message then the hash value will change and so can detect such a change. Attacks such as denial of service attack threaten availability. For example, say a situation where millions of false requests are sent to a web server until it is down or the response time becomes too high. Techniques such as firewalls are used to prevent such attacks. So security means providing the three service confidentiality, integrity and availability using various technologies such as encryption and hash functions.
什么是隐私?
Privacy is a similar term forconfidentiality。只有在这里预期或授权方应能够分享秘密虽然未经授权的政党无法找到秘密。隐私是提供安全性时最重要,最关键的事情之一。如果隐私违反,则安全性会受到影响。因此,隐私是安全的一部分。安全性涉及提供保密性(隐私),完整性和可用性等服务,而隐私是一种安全性的服务。说,在某个公司中,总部与分支机构通过互联网。If some黑客can acquire sensitive information, then the privacy is lost. So techniques such as encryption is used to protect the privacy. Now the employees on both sides know a secret key that only they know and any communication can be decoded only using that key. Now a hacker cannot gain access to information without the key. Here, the privacy depends on keeping the key secret. Privacy can be with respect to a single person as well. An individual can have data which he needs to keep private for himself. So, in such situation also, encryption can help to provide that privacy.
隐私和安全性有什么区别?
• Security refers to providing three services confidentiality, integrity, and availability. Privacy or confidentiality is one of those security services. So, security is an umbrella term where privacy is a part of it.
•提供安全性可能比提供隐私权更为昂贵,因为安全性也涉及隐私以外的其他服务。
•侵犯隐私也意味着违反安全性。但是违反安全并不总是意味着违反隐私。
Summary:
Privacy vs Security
安全是一个广泛的领域,保密或隐私是其中的一部分。除了提供隐私外,提供安全性意味着提供其他两项服务,即诚信和可用性。为了提供隐私,最常用的技术是加密。隐私意味着仅在授权人群中保密。如果秘密被泄露,那是违反隐私的,并且也违反了安全性。

不太同意如何提出上下文。
还有另一个方面。由于安全措施的提高,个人的隐私已大大降低。
因此,人们可以假设安全性的提高将降低隐私,反之亦然!!!

布鲁斯·施尼尔(Bruce Schneier)在2006年5月18日发表:“隐私的永恒价值”上说:
“最常见的对隐私拥护者反驳— by those in favor of ID checks, cameras, databases, data mining and other wholesale surveillance measures — is this line: “If you aren’t doing anything wrong, what do you have to hide?”
Some clever answers: “If I’m not doing anything wrong, then you have no cause to watch me.” “Because the government gets to define what’s wrong, and they keep changing the definition.” “Because you might do something wrong with my information.” My problem with quips like these — as right as they are — is that they accept the premise that privacy is about hiding a wrong. It’s not. Privacy is an inherent human right, and a requirement for maintaining the human condition with dignity and respect.
两个谚语说得最好:奎斯·托迪特·托管ipsos?(“谁看着观察者?”)和“绝对权力绝对破坏。”
红衣主教Richelieu理解了监视的价值,他著名地说:“如果有人给我六行用最诚实的人写的六行,我会发现其中的东西让他挂了。”观看足够长的时间,您会发现一些可以逮捕的东西,或者只是勒索。隐私很重要,因为没有它,将滥用监视信息:窥视,出售给营销人员并监视政治敌人 - 无论他们当时碰巧是谁。
Privacy protects us from abuses by those in power, even if we’re doing nothing wrong at the time of surveillance.
当我们做爱或去洗手间时,我们没有做错任何事情。当我们寻找私人场所进行反思或对话时,我们并没有故意隐藏任何东西。我们保留私人期刊,在淋浴的私密性中唱歌,然后写信给秘密恋人,然后燃烧。隐私是人类的基本需求。
A future in which privacy would face constant assault was so alien to the framers of the Constitution that it never occurred to them to call out privacy as an explicit right. Privacy was inherent to the nobility of their being and their cause. Of course being watched in your own home was unreasonable. Watching at all was an act so unseemly as to be inconceivable among gentlemen in their day. You watched convicted criminals, not free citizens. You ruled your own home. It’s intrinsic to the concept of liberty.
For if we are observed in all matters, we are constantly under threat of correction, judgment, criticism, even plagiarism of our own uniqueness. We become children, fettered under watchful eyes, constantly fearful that — either now or in the uncertain future — patterns we leave behind will be brought back to implicate us, by whatever authority has now become focused upon our once-private and innocent acts. We lose our individuality, because everything we do is observable and recordable.
How many of us have paused during conversation in the past four-and-a-half years, suddenly aware that we might be eavesdropped on? Probably it was a phone conversation, although maybe it was an e-mail or instant-message exchange or a conversation in a public place. Maybe the topic was terrorism, or politics, or Islam. We stop suddenly, momentarily afraid that our words might be taken out of context, then we laugh at our paranoia and go on. But our demeanor has changed, and our words are subtly altered.
This is the loss of freedom we face when our privacy is taken from us. This is life in former East Germany, or life in Saddam Hussein’s Iraq. And it’s our future as we allow an ever-intrusive eye into our personal, private lives.
太多错误地将辩论描述为“安全与隐私”。真正的选择是自由与控制。暴政,无论是在外国身体攻击的威胁下还是受到国内权威的持续权威审查,仍然是暴政。自由需要安全,而无需入侵,安全加隐私。广泛的警察监视是警察国家的定义。这就是为什么即使我们没有什么可隐藏的,我们也应该拥护隐私。”
