過去簡單式

Twenty-five years ago, scientists at CERN
created the World Wide Web.

25 年前，歐洲核子研究組織的科學家
創造了全球資訊網。

Since then, the Internet has transformed 
the way we communicate,

自此之後，網路改變了我們溝通、

the way we do business,
and even the way we live.

the ideas that gave birth to Google,
Facebook, Twitter, and so many others,

這個概念也催生了谷歌、
臉書、推特和無數網站，

and this has brought us many real benefits
such as a more connected society.

並帶給我們許多實質上的助益，
例如關係更緊密的社會。

However, there are also
some downsides to this.

Today, the average person
has an astounding amount

現在一般人放在
網路上的個資多得嚇人，

and we add to this online information
every single time we post on Facebook,

或是寄封信
都會在網路上添加一筆個資。

一封電子郵件而已，
裡面沒什麼資料吧？

well, one email,
there's nothing in there, right?

但是如果你評估一整年的電郵，

But if you consider
a year's worth of emails,

可以透露我們去了哪裡、
和誰見了面，

It tells where we have been,
who we have met,

甚至能從許多方面了解
我們在想什麼。

and in many ways,
even what we're thinking about.

更恐怖的是現在
我們的資料會永存於世，

And the more scary part about this is
our data now lasts forever,

所以你的資料能夠也將會
比你活得還要久。

What has happened is that we've largely
lost control over our data

很重要的是我們應該要花點時間

it's very important for us
to take a moment

and think about the implications of this.

但其實我們也失去了
「隱私」這個概念。

but actually what we've also lost
is the idea of privacy itself.

在座大多數人應該都記得
還沒有網路的生活是什麼樣子，

most of us here today probably remember 
what life was like before the Internet,

從很小的時候就學會上網分享大小事，

that is being taught from a very young age
to share everything online,

這個世代不會記得
有隱私資料的年代是什麼樣子。

and this is a generation that is not 
going to remember when data was private.

So we keep going down this road,
20 years from now,

「隱私」兩字就會有全然不同的意義，

the word 'privacy' is going to have
a completely different meaning

因此現在我們該花點時間思考，

So, it's time for us 
to take a moment and think,

我們來看看現在世界上
最普遍的溝通方式：

Let's take a look at one of the most
widely used forms of communication

在電子郵件發明前，
我們大多靠信件連繫，

Before the invention of email,
we largely communicated using letters,

You would first start by writing
your message on a piece of paper,

then you would place it
into a sealed envelope,

and from there,
you would go ahead and send it

你只要貼郵票、寫地址就可以了。

我們寄的其實是電郵，而非信函。

when we actually send an email,
we're not sending a letter.

從多方面來看，
你寄的其實是明信片，

What you are sending, in many ways,
is actually a postcard,

and it's a postcard in the sense
that everybody that sees it

從你的電腦寄出
到收信人收到的這段時間，

from the time it leaves your computer
to when it gets to the recipient

解決方式已廣為人知一段時間了，

So, the solution to this
has been known for some time,

The most basic solution
is to use encryption,

首先，將你的電腦
和電郵伺服器間的連結加密，

然後資料擱在伺服器的時候
也要加密資料。

between your computer
and the email server.

Then, you also encrypt the data
as it sits on the server itself.

因此你有個超級大鎖，
鑰匙就放在旁邊。

and that is, the email servers
also hold the encryption keys,

不只是這樣，所有政府都能依法要求

so now you have a really big lock
with a key placed right next to it.

But not only that, any government
could lawfully ask for

我們解決這個問題的方法
其實很簡單，從理論上講，

and this is all without you
being aware of it.

So the way we fix this problem
is actually relatively easy, in principle:

and then you make sure the server
doesn't actually have the keys.

問題來了，
為何到現在都還做不到？

So the question that comes up is,
why hasn't this been done yet?

we see that the business model
of the Internet today

只要看網路上最大的幾個網站，

你就會發現廣告扮演極大的角色。

Just take a look at some
of the biggest names on the web,

事實上，它們光是今年
廣告費就花了 1370 億美元，

and you see that advertising
plays a huge role.

為了讓我們看到的廣告
效果發揮最大功效，

In fact, this year alone,
advertising is 137 billion dollars,

and to optimize the ads
that are shown to us,

companies have to know
everything about us.

年紀多大、喜歡什麼、討厭什麼，

how old we are, what we like,
what we don't like,

and anything else
they can get their hands on.

要得到這些訊息的最好方法
其實就是侵犯我們的隱私。

所以這些公司才不會給我們隱私。

the best way to get this information
is really just to invade our privacy.

如果你想要在網路上擁有隱私，

So these companies
aren't going to give us our privacy.

就必須自己挺身而出、去爭取。

多年來，談到電子郵件隱私的時候，

what we have to do is
we've got to go out and get it ourselves.

解決方式就只有
良好隱私密碼法 (PGP)，

不僅十分複雜，
而且只有科技達人才會懂。

the only solution
was something known as PGP,

which was quite complicated
and only accessible to the tech-savvy.

不用說，這個方法不是人人適用，

the process for encrypting
and decrypting messages.

So needless to say,
this is not a solution for everybody,

and this actually is part of the problem,

定義上來說，
就是要和另一個人溝通。

because if you think about communication,

因此良好隱私密碼法
如期發揮強大功效的同時，

by definition, it involves
having someone to communicate with.

So while PGP does a great job
of what it's designed to do,

for the people out there
who can't understand how to use it,
