Why protect his private life on internet?


I guess if you have landed here is that you ask questions about your private especially on the internet. Indeed, the list of news items on people who have had their lives destroyed because of the web continue to grow ( here there or here ) and you end up asking yourself, and if it happened to me

(thank you for the shot clip)




I would first like to congratulate you, you have perfect behavior 😀 Questioning the protection of privacy on the Internet today is give you the means to avoid the worst: see your intimate life raped, exposed to others and watch your life become a nightmare. But it will not happen! Because you are there, and you a few minutes to read all the dangers – real – present on the internet that undermine your privacy . This is the starting point of awareness, this article is the first in a long series that will let you know how to protect yourself face these dangers.

But first, let me explain why protect her privacy is crucial even vital for each of us. Then I’d try to make you aware of the real dangers you incur on the internet and you are for sure exposed to the time you read this.

The importance of privacy in our daily lives

I do not teach you if I say that each of us has privacy its own.

Indeed hitherto thou teach me anything!

Wait I just started my article! 😀 And before the start, moreover, I would like you to grasp how have a private life is essential for good living your daily life.

The privacy , what is it anyway? One could say that this is all the activities that fall within our privacy by opposition to public life . These are all the things we attach special and personal feelings, our secrets, our desires, our desires, our beliefs, everything that defines us more as a unique and we want to keep to yourself, without this be known to the outside, in public life.

This notion of privacy varies depending on each of us. It is for everyone to estimate degree of deprivation he wants to give her privacy .

Whether one likes or only shared with people you trust, our privacy allows us to free ourselves from the pressure of the outside world and be truly ourselves. Each of us has need to have a private life , to meet, to protect others and develop. It is a human need to live and be happy! 🙂

Why protect his privacy?

Protecting your privacy ? I do not see the point, I have nothing to hide!

Well … in fact if, like me, you have a lot to hide! 😉 And even if you do not realize you already not hide bad things :-p must not be mistaken if we hide things, it is not necessarily the wrong things or illegal. It’s just natural, you need to have a secret garden to meet and ensure its balance often abused by public life. The privacy is essential to ensure our stability and well-being. It is a basic human need.

By showing us fully and publicly, we are more vulnerable to the outside world : we are exposed to rumors, defamation and violation of privacy. Malicious people can easily exploit our personal information – it is considered commonplace yet – to harm us. You know and I know the violence of the outside world and the fragility of our reputation, daily subjected to criticism and judgments.

Protecting your privacy is guaranteed to have a mastered and serene life.

Why our privacy is at risk on the internet?

This is our internet privacy is the most vulnerable.

I agree but I’ll be honest with you the Crab … I do not feel safe when I’m online!

The main problem on the internet is that everything happens there does not directly and physically affect the people who are its victims. When sites or hackers collect our personal data (photos, visited sites, communications …) we do not see, do not feel it, nor understand it. possibly we can notice it at an end, when evil will be done ( identity theft with false statements, refusal of a post because of words or pictures doubtful …). Apart from this type of event, the phenomenon remains completely imperceptible. Therein lies the difficulty: to be aware that even if we do not feel there is a danger


Well OK but in this case, where is the danger?

Let me introduce you to the guilty! 😀

Social networks

is not going to lie, we are almost all present on social networks (Friend Crab including :-p). On Facebook for example, we have become accustomed to – with confidence and without being aware of the potential risks – of personal information and share our daily lives . The social networks (Facebook, Twitter, Google+, etc.) as part of the public eye, we therefore expose our privacy a number of people, which is d Besides not easy to determine.

T’inquiète the Crab, I run no risk! I reveals nothing that would endanger myself, everything I put purely futile!

Hmm, are you really sure?

Many people were victims of their vis-à-vis the danger posed unconsciousness social networks on their privacy . I’m not here to make you moral, just to warn you (for I love you :-p).

I assure you: it does not happen to others! To convince you, I invite you to watch this short documentary (15min): he has a girl who was made hack their Facebook account unquestionably poorly protected. The hacker can be anyone, a person like you and me, there is no need for advanced technical knowledge to run this kind of intrusion. Therefore, this pirate got in touch with the circles of knowledge of this girl and severely soiled his image. Guess the consequences on his life.

This is one example among many others who have not had the chance to be publicized (from a pedagogical point of view). The report also shows how it is – very – easy steal information about someone through Facebook


Longer but also more interesting long report shows us more including two striking stories. The first is a girl, prey to cyberstalking , which almost ended his life. And the second that of a man identity theft victim . I urge you to look at this very interesting report!

The so-called web services “free”

How many of us use free services as Gmail, YouTube, Instagram, Twitter, etc. ? You understand that if we do not give them a dime, it must be that these companies go get the money somewhere!

I’ll probably surprise you but if it’s free, it’s the product you ! Indeed, these are all personal information stored, analyzed and then sold to other companies so that they can provide you with highly targeted advertisements and get you to buy their wares. With all this information, these companies even manage to create a need that has not yet emerged in our mind. Personally I do not know about you, but I did not want people to know me by heart and that makes me want to buy something, it creates a need me. I just want to buy the things I need, not those that make me dangled a more beautiful life with them.

For information, here are the terms and conditions of the three services we use probably the most: Google (Search, Gmail, YouTube …) Facebook and Twitter . You know the ones you never read 😀 Well I you extract the interesting passages! I invite you to read them for you to realize that everything we do on these services is recorded ad vitam aeternam, used and sold.

This is why we must be careful. Beyond the moral appearance (I did not want people stealing my information!), We also know that these services are far from infallible. Imagine that people come to break the security of your account and to retrieve all your personal data (photos, emails, private conversations, photos, friends list, place of residence, phone numbers …) : you can quickly imagine the unhealthy use he could make …

At Google:

you give Google (and anyone working with Google) a license […] reproduction, modification, public display or public distribute such content. This authorization remains for the entire legal term of protection of your content, even if you stop using our Services.

At Facebook:

You grant us a license transferable, sublicensable […] to use any IP content that you post on Facebook. This license […] ends when you delete your IP content or your account unless your account is shared with other people who have not deleted.

You understand that removed content may persist in backup copies for a while (but they are not available.)

At Twitter:

You grant us a license […] including the right to grant a sub-license to use, copy, reproduce […] this Content in any medium. You authorize us to make your Tweets available to the rest of the world.

You agree that this license includes the right for Twitter […] to the content published or transmitted through the Services available to other companies, organizations or individuals who partner with Twitter.

The web monitoring

You are aware that all our internet activities are monitored and stored by intelligence agencies. This is to “ensure our security.” These include the NSA PRISM program with its “upstream” and xkeyscore. For more information, you can watch this short video that explains how the NSA is watching (explained in potatoes!)

Let me spying, I do not care! It does absolutely nothing to change my life to be monitored!

I do not agree and I think you’re not agree with what you say 😉 To help you understand why monitoring a danger and why it can radically change our daily life , I invite you to read about Jean-Marc Manach I find very relevant:

If we are seen on every occasion, we are constantly threatened correction, judgment, criticism. We become children […] constantly fearful that – either now or later – the tracks we leave we catch up , through the fault of an authority whatsoever that now bears his attention to acts which were the innocent and private time. We lose our individuality, because everything we do is observable and recordable
. Source: Privacy, a problem of old farts


The privacy in itself, who cares, it’s just an average. It’s like Internet, we do not care, it’s just an average. There is no freedom of expression, no freedom of movement, there is no freedom of opinion if there is no privacy . Because if we feel secure we will censor .

If you think that these oversight bodies are not interested in you and do not store any of your actions, think again! Even if you think your life is more mundane, there is very likely that you are still monitored at present:

The NSA when she looks at a target, and will also be of interest to all people who are in contact with it, plus all the people who are in contact with those who are in contact with it, etc. at three levels.

The question is not whether we have anything to reproach; the question is to know is that we know someone who knows someone who knows someone? And as we know that on Facebook, on Twitter, we’re all in four levels of separation from other , yes, virtually, [ils] give themselves the right of spy a little all world
. Source: from the mass surveillance to widespread paranoia

Yes I do nothing wrong!

The problem is that it is not itself determine whether one is guilty or not: these are computer systems with their algorithms that scan our profile and decide whether or not we have to be stuck. Therefore, all our activities will be recorded . But if you are really sure not to do anything wrong, I invite you to leave me your password to access your mailbox and your Facebook account 😀 The problem is that we always end up finding something when you really want find …

You see, it is in principle for the preservation of democracy, for the respecting our privacy , that we must fight against this surveillance. And there is obviously the means to defend ourselves!

The tracking, profiling and behavioral targeting

The tracking on profiling and behavioral targeting are the stages of a marketing intelligence that we suffer silently.

Why so much hatred towards us?

Just because the Internet business model is based very largely on advertising revenue . This is the counterpart of this apparent free all services and websites that are used daily.

How does this spying?

Everything starts with tracking : This is all the means in place to we identify and prosecute us throughout our browsing on different websites. Specialized companies that implement it tracking have huge databases containing all our past activities: favorite, searched keywords sites name, address, shopping list, contacts, centers interest …

This is then around profiling come into play: it performs an analysis of our data – collected through tracking – in order to establish a precise profile of ourselves and determine our behavior.

Finally behavioral targeting gives the coup de grace: it builds on our profile generated by profiling for we broadcast commercials ruthlessly efficient. As they know everything about us (our interests, our behavior, our current and professional situation …), advertising agencies know where, when, what and how we distribute advertisements to push us to buy. The doctrine of marketing in short: deliver the right message at the right time, to the right person through the right channel


The sal * ps !!! But through which technical means they manage to implement this system?

What vulgarity! 😀 But your determination pushes me to list the ways you (as you probably know) in place to ensure this espionage.

tracking cookies

What’s a cookie?

A cookie is a text file that is placed on your hard drive when you are a website and that is returned to the same website the next time you return. It’s that simple ! 🙂 This is the website itself that chooses to file this cookie. He may file one or more and manipulate them as they wish.

The primary interest of cookies is to allow websites to keep on our computer data they can access later. For example, a website can store useful information to improve our navigation : our preferences (website language, font size), the pages already read for us propose different, our geographical position to connect us to the nearest server, thus accelerating the speed of the site …

The cookies are temporary or have a validity date (set by the cookie creator). They can not be manipulated by the cookie’s creator. Another site may view or edit the cookie from another site.

These are the browsers that physically manage cookies on behalf of the plaintiffs sites. We can now view, edit or delete them ourselves within the browser:


Visualization cookies in Firefox

The content of the cookies is often encrypted to make them difficult to handle and interpret. Also, sometimes the content is compressed so that the cookies take up less space (in fact, they are limited in size).

But after what you told me, it looks great that cookies!

It could be! 😀 But as often, some tools are used for evil … and so the Cookies! 🙂 Thus the tracking cookies were born. Used by large companies as well hairy Google or Facebook, they can establish a behavioral profile of each of us.

The ad servers

You should know that most internet advertising is handled by ad servers that connect a large number of advertisers with a large number of websites that have signed an agreement to display advertising. So when visit exemple.com you might well view ads have been placed there by serveurdepub.com . later when you visit another site , for example exemple2.com , you could also see ads that were also placed there by the same ad server, pub. serveurdepub.com .

What relationship with cookies?

The ad servers – as serveurdepub.com – store certain types of cookies on our computer: of tracking cookies . These are used to establish a behavioral profile of each of us.

What? How is this possible with a simple cookie?

I’m here to help you understand all my friends 😀 I’ll show you how the ad servers manage to keep a complete history of all the websites you visit – even those you are less proud :-p – thanks to tracking cookies .


Source: askleo.com

We saw just now, when you go to exemple.com This website may set cookies in your browser . However if a page of exemple.com uses another site as web serveurdepub.com to display advertisements serveurdepub.com can also file cookie in your browser . It’s a little party at the village you visit a site, it can set cookies in our browser. And sites that provide additional content for that site (images, videos, commercials …) may also set cookies.

Nothing like a good example to see more clearly and understand how an ad server can recover all the sites you visit through a tracking cookie

  • You are going to exemple.com

  • exemple.com has ads that are loaded from serveurdepub.com

  • The first time you visit exemple.com serveurdepub.com drops a cookie in your browser contains a GUID, a unique identifier that identifies you: visitors = 856d-d24f34e04a6d

  • Then you go to another site exemple2.com

  • exemple2.com also displays advertisements loaded from serveurdepub.com

  • Like serveurdepub.com has already filed a cookie in your browser, the same cookie is sent to serveurdepub.com when the commercials from the latter will be responsible

  • serveurdepub.com reads the cookie, which told him that you are visitor 856d-d24f34e04a6d

  • That’s it! serveurdepub.com now knows you’ve visited both exemple.com and exemple2.com

The principle of encirclement made in Google

Ok but all websites do not necessarily use serveurdepub.com , then these ad servers can not know ALL the web sites I visit!

Well done! serveurdepub.com only know the sites you visit from the sites that choose to display ads from serveurdepub.com . But if I tell you that ad server is only one of many tentacles of an octopus like Google who wants to know everything about you? I remind you of the “few” services that Google offer on the web:

  • Search: Google Search

  • Audience Analysis: Google Analytics. This tool is used by almost all the directors on their websites. End of 2014, Google Analytics was used by 70% of the 25,000 most visited French sites (source: Le Journal du Net )

  • Advertising: Google Adwords, Adsense. Same, these advertising tools are widely used and integrated into most websites

  • Productivity: Gmail, Contacts, Calendar

  • Cloud: Google Docs, Drive, Photos

  • And also: Google News, Maps, Google+, YouTube, Blogger, etc.

Now if I tell you that each of Google services use tracking cookies to spy on you? By comparing the data it collects about you (thanks to the services you use – YouTube, Gmail, Google Search …), all the sites you visit, the videos you watch, your driving directions, your location, your emails, your research, contacts, etc., he knows more about you than yourself 😉

Google is a perfect example but there are others like him octopus through the web (Facebook to name him). But Google is still THE reference and octopus THE quintessential 😉

The spy pixels or “web bugs”

What is a web bug?

A spy pixel is a spy, hidden in a web page, in the form of micro image of a pixel (1 × 1), transparent and invisible for us surfers.

The spy pixel is the same as a commercial. Associated with tracking cookies, they are there to collect information about your activities on the Internet.
