You Are Being Watched: Open Society vs Surveillance

Do you believe, if I say that you live in a science fiction world? Let’s begin with a short story.

Today I took the public transport to office and on my way, I had breakfast at a coffee shop till I reached my destination, I met several individuals; a bus driver, the person who is seated next to me on the bus, and the waiter who served me coffee.

But what would have happened if, the bus driver kidnapped me and asked me for ransom? Or the person seated next to me threatened my life to steel my purse? Or the waiter at the coffee shop poisoned my food?

Society doesn’t work like this, society works on trust. The nature of society requires some measure of trust and humans are a trusting species. 

“Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure, or nothing.”
Helen Keller

Trust is a complicated concept, and this word is overloaded with many meanings. All complex ecosystems require cooperation and trust. This is true for biological ecosystems, social systems, and sociotechnical systems. Also, in any cooperative system, there also exists an alternative parasitical strategy. A tapeworm in your digestive tract, thieves in a market, spammers on e-mail, and people who refuse to pay their taxes. These parasites can only survive if they're not too successful. That is, if their number gets too large or too powerful, the underlying system collapses. If there are too many tapeworms in your digestive tract, you die and they die. Too many thieves in a market and no one visit the market anymore and the thieves starve. Too many people stop paying their taxes, and you get Greece [by: Bruce Schneier].

Most of us recognize this, that it's not in our long-term best interest to act in our short-term self-interest. But not everyone follows this truth. That's why we need mechanisms to induce trust and why we need security. 

Nowadays we hear lots of terrorizing news such as; cyber terrorism, cyber war and cyber crime. 

Cyber War it’s not a military action, where there are guns, bombs and people dying. (We love to use the word ‘war’ where there is no war - war on terror, war on drugs and war on crime but ignore or dislike using the word ‘war’ when there is an actual war. We will say anything else other than war.) In a real war situation, you most often know ‘who’ is attacking and ‘why’ they are being attacked. But in Cyber War you don’t know when, why or who is attacking. To control cyber threats, we need lawful surveillance. Once again ’lawful’ is a complex word.

The number 3000 - This is the number of times a single citizen is surveillance in UK with 5 million CCTV cameras with in 24hrs, and most heavily surveillance country in the world.

What does privacy mean and why it’s important?
Privacy is the right to be left alone, or freedom from interference or intrusion. Information privacy is the right to have some control over how your personal information is collected and made use of.

Have you ever questioned yourself: ‘How Much Does Google Really Know About Me?’ Believe me, they know more than your wife. So we have lost our privacy


Privacy & security - isn’t is the same thing? No, not real but they are first cousins. Security and privacy are not opposite ends of a seesaw; you do not have to accept less of one to get more of the other.

"If you aren't doing anything wrong, what do you have to hide?"

Data privacy is focused on the use and governance of personal data, on the other hand security focuses more on protecting data from malicious attacks and the exploitation of stolen data for profit.


When Edward Snowden leaked massive troves of information about the National Security Agency's collection of electronic data and started a debate over the trade-offs between security and privacy. Unfortunately, the security vs privacy debate is largely over. As cyber-technologies pervaded our daily lives, we surrendered privacy, usually voluntarily. Consequently, framing the decisions before us as a contest between privacy and security is misguided; privacy died with the information age.

Are we surrendering our privacy for technology? A BIG yes but Information and Communication technologies also make life better. It improves productivity, efficiency, and economic growth and such benefits come at a price. Simply look at your mobile phone. This is a cute, sleek and an incredibly powerful tool which has become so central to our lives that we take it for granted. It seems perfectly normal to pull this device out of your pocket, no matter where you are on the planet, and use it to talk to someone else no matter the location. You are making an implicit bargain with the carrier: “I want to make and receive mobile calls; in exchange, I allow this company to know where I am at all times.” A mobile phone can’t work unless the mobile companies know where you are, which means they keep you under their surveillance.

“Everything around you, you called life was made up by people and no smarter than you. You can change it, you can influence it, you can build your own things, so then other people can use.”


Your cell phone tracks where you live and where you work. It tracks where you like to spend your weekends and evenings. It tracks how often you go to church (and which church), how much time you spend in a bar, and whether you speed when you drive. It tracks—since it knows about all the other phones in your area—whom you spend your days with, whom you meet for lunch, and whom you sleep with.

Let me explain simple terms. In a public place, whatever the place you think of, an unknown person approaches you and asked your personal details (it can be your name, age or mobile no). Will you give out this information? 

Nearly 99.9% will say ‘NO’, because the person is unknown to you & why should I give it to an unknown person? When the enemy is known, we defend us, if unknown, we expose more than the enemy wants, this is what happens in this information age. 

Now, how many of you have social network accounts (Facebook, LinkedIn)? Do you know how much of personal details we are uncovering? On the other hand, social networking plays a bigger role in our lives. We need social network, to be connected with our friends, to business for marketing and for exposer. Technology evolution comes with a price; we have to bare it. 

“There is no patch for stupidity.”

- Kevin Mitnick

In 2013 Edward Snowden the whistle blower, sacrificed his life and exposed NSA’s secret surveillance. The whole world got shocked that we are under surveillance; subsequently US official said that they are not collecting personal information (content), collecting only “meta-data” (context). The intended point was that the NSA wasn’t collecting the words we spoke during our phone conversations, instead, they collect only the phone numbers of the two parties, and the date, time, and duration of the call. 

Collecting metadata on people means putting them under surveillance. Imagine that you hired a private detective to eavesdrop on someone. The detective would plant bugs in that person’s home, office, and car. He would eavesdrop on that person’s phone and computer. And you would get a report detailing that person’s conversations. 

Now imagine that you asked the detective to put that person under surveillance. You would get a different but nevertheless comprehensive report: where he went, what he did, who he spoke with and for how long, who he wrote to, what he read, and what he purchased. That’s metadata & metadata is surveillance data.

Telephone metadata alone reveals a lot about us. The timing, length, and frequency of our conversations reveal our relationships with others: our intimate friends, business associates, and everyone in-between. Phone metadata reveals what and who we’re interested in and what’s important to us, no matter how private. It provides a window into our personalities. It yields a detailed summary of what’s happening to us at any point in time.


Over the period of time, accumulated personal data can probably paint a better picture of how you spend your time than you can, because it doesn’t have to rely on human memory. Most of us have at-least one or more social network accounts, and do various activities. Adding our friends, new posting, status updates, chatting & many more activities.

Web search data is another source of intimate information that can be used for surveillance. (You can argue whether this is data or metadata. The NSA claims it’s metadata because your search terms are embedded in the URLs.) We don’t lie to our search engine. We’re more intimate with it than with our friends, lovers, or family members. We always tell it exactly what we’re thinking about, in words as clear as possible. Google knows what kind of porn each of us searches for, which old lovers we still think about, our shames, our concerns, and our secrets. If Google decided to, it could figure out which of us is worried about our mental health, thinking about tax evasion, or planning to protest a particular government policy. I used to say that Google knows more about what I’m thinking of than my wife does. But that doesn’t go far enough [by: Bruce Schneier].

" Eavesdropping gets you the conversations (content); surveillance gets you everything else (context)”

Google’s CEO Eric Schmidt admitted as much in 2010: “We know where you are. We know where you’ve been. We can more or less know what you’re thinking about.” You may ask how do they can do this? One way to think about it is that data is content, and metadata is context. When you have one person under surveillance, the contents of conversations, text messages, and emails can be more important. But when you have an entire population under surveillance, the metadata is far more meaningful. One way to think about it is that data is content, and metadata is context. Metadata can be much more revealing than data, especially when collected in the aggregate.

Think about the day to day activities; shopping at supermarket. How many of you have privilege cards? Think of a simple activity, at the supermarket cashier you give privilege card to gain points. We use that gain points so that we can redeem one day. Do you know how much of personal information can be gathered by this? When we register for a privilege card we give our name, address, contact no and much more to the supermarket. When do shopping, this privilege card and credit cards are associated with our bill. By doing this we share our shopping pattern, our personal information, our banking information. And our shopping pattern can be matched by the product companies and special discounts.

Not only that, now we get wearable device (Google glass, Bio sensors), IoT devices picking up in technology era. All these devices generate data about you and surroundings. Recently Google claims their quantum computer is 100,000,000 times faster than a classical computer, in simple terms, an instruction can be executed in a hundredth of a second; with a classical computer it’d take about 100 days.

Sunny Kim, State University of New York, Albany, where she studied economics, after graduation she returned to South Korea to take up a job. But she stayed connected with her US friends on Facebook and the messaging app KakaoTalk. In South Korea, she met a man who would become her boyfriend. She’d regularly share snaps of them together on Facebook. Kim also regularly posted pictures of her friends, crafts, food, and her puppies to Facebook. A friend told BuzzFeed News: “It seemed like she was happy, eating and living well.” Kim went missing on 2 May, according to reports. On 18th May Kim’s body was found in a suitcase buried in a hill. Her boyfriend confessed to her murder. Kim’s sister said she didn’t realize Kim was dead at first, because Lee impersonated her for two weeks by responding to texts sent to her phone.

If Lee can impersonate for two weeks -why can’t a super computer?

This is day may not be too far.

7 Tips for Effective Presentation

What does Presentation Mean?

Presentation is the rehearsal of performance and the explanation of the content of a theme to viewers or students. In the business world, we have sales presentation, informational and motivational presentation, first encounters, interviews, briefings, status report, image building and training sessions.

What is Presentation skills?

Presenting information clearly and effectively is a key skill to get your message or opinion across and, today, presentation skills are required in almost every field.

Whether you are a student or manager, if you wish to start up your own business, apply for a grant, you may very well be asked to make a presentation. 

Many believe that good presenters are born, not made. This is simply not true. Sure, some people are more relaxed and comfortable speaking in front of others, but everyone can learn the skills and techniques they need to increase their level of confidence and performance when presenting.

From sales pitches to training lectures, good presentation and public speaking skills are key to many influential roles in today's business world. The good news about presenting is that you can improve with practice. Following tips may offer some guidance to help you on the way to delivering a memorable presentation.

1. Preparation, preparation, preparation

There is no easy way out. Giving a excellent presentation is all about the preparation that goes into it, and this theme applies to every single aspect you include in your presentation. Prepare and structure your presentation carefully. Introduce the subject tell the audience what your talk is about. Explain the points you wish to convey. End with a summary of your points.

Write down the main points on a paper. Don't write details, or be stuck with the fate of looking down, staring at your note cards while reading. Put in some fun facts interactive questions, and other interactive activities on the cards to share with the class.
Most of the time, the act of putting information down on your index cards will help you remember the information. So, while you might not strictly need the note cards, it's a nice security blanket to have if you happen to forget what you were going to say.




2. Think of the audience & Do your Research

When you are preparing your presentation, there is one thing you should always keep in the back of your mind: the audience. The sole purpose of a presentation is to communicate whatever you have to say to an audience. Position yourself being in their shoes and answer the following questions: who, what, why, how?

Who are they and who are you? It’s essential to know who your audience will be: are they your classmates, professors, professionals, etc. and what do they know about you. Do you need to inform them? Do you need to introduce yourself? Different audiences have different needs, and different audiences may need different communicative approaches.

What do they want? What do they know? What can I tell them? Knowing this information will help you decide what content to include in your presentation. If you are not sure about the answer to one of these questions, perhaps you may want to include it in your presentation.

Where can I take them? Your presentation is very much like a journey. Guide your audience through the content. Use signposts to indicate what you are presenting and where you are going. Examples of signposts are, “Next, I will discuss..”, “Now I’d like to move on to….”, and “Finally, …” or “To conclude..”. Signposts are also great tools to keep you audience awake, focused and engaged. Have you ever listened to a less engaging presentation and the presenter said, “Finally”, surely that was the moment you found yourself waking up. Use signposts throughout your presentation.


Do your research. In order to give an engaging presentation, you need to know what you're talking about. You don't have to become an expert, or read every book or website ever written about your topic, but you should be able to answer any questions your teacher or classmates might give you.

Get quotes from reliable sources. Good quotes make a good presentation great. Taking what smart people have said and putting it into your presentation not only makes you look smart, it shows the teacher that you spent time thinking about what other people said.


Make sure your sources are trustworthy. There's nothing that can quite break your confidence like a fact that turns out to not be a fact. Don't always trust the information you get off the Internet.



3. Structure your presentation

The purpose and content needs to be carefully considered. How much detail can you cover in the allotted time? Going back to a point made earlier, what does your audience already know about your topic? What do they need to know, and more important, what is your take-home message? What do you want your audience to remember?

Most presentation will have an introduction, a body, and a conclusion. You introduce yourself in the introduction, your topic, and what you will cover during your presentation. Remember, this part can be as short as 30 seconds. 

The body will include key points, new knowledge, trends in your data, or progress to date. The level of detail may depend on the task and time available. Highlight the implications of your discussion or possible applications of your findings in your conclusion and finish with your take-home messages.

4. Practice

In most presentations, it is pretty obvious who has practiced and who hasn't. Work on what you're going to say and how you're going to say it. You'll feel a lot more confident when you do the real thing and you'll eliminate the "likes" and "ums" unlike those who try to "wing it."
  • Practice in front of your family or friends, or in front of the mirror, when you rehearse your presentation. It's probably better to do it in front of friends who you may not know well, as this will help you replicate the feeling of being in front of the class.
  • Ask your friends for feedback after you finish your presentation. Was the presentation long enough? How was your eye contact? Did you stammer at all? Were all the points clearly made?
  • Make a critique of your practice performance. Challenge yourself to work on all the things that you believe you can improve during the real presentation. When it comes time to deliver the real deal, you'll feel confident knowing that you've worked extra hard on what was toughest for you.


5. Communication

Smile at your audience. When it comes time to present, there's nothing that draws your audience into your presentation than a good old fashioned smile. Be happy; you're about to teach your entire class something they didn't know before.


Studies have shown that smiles are infectious[1]; that means that once you smile, it's hard for everyone else not to smile. So if you want your presentation to go off without a hitch, force yourself to smile. That'll make everyone smile; and maybe those smiles will make you actually smile.

A presentation is never a one way communication, despite the fact that you are the only one speaking. Communication is always two ways. Vary the tone, pitch and volume of your voice to add emphasis and maintain the audience’s interest. Although you do not want your audience interrupting your speech, make it engaging: look at the audience, speak loudly and clearly, speak to the whole audience. Match eye contact with everyone in the room. 

Your audience wants to be spoken to. Ask rhetorical questions, use short pauses when you are, for example, changing the subject or moving on to another topic. Rhetorical questions will often raise the audience awareness as do pauses. Don’t hide behind a computer, a paper, or a desk.

When you give your class a presentation, your teacher is essentially having you take over their job for a little while. It's your job to make sure everyone understands what you're trying to tell them. Make sure you pay attention to how your teacher does this before your presentation, because teachers are expert presenters. Build confidence on yourself.


Make eye contact
Nothing is more boring than listening to a presenter who looks at the floor or at note-cards. Relax. Your audience is made up of your friends and you talk to them all the time; talk the same way now.

Have the goal of looking at every person in the classroom at least once. That way, everyone will feel like you've engaged with them. Plus, you'll look like you know what you're talking about.

Be sure to have inflection in your voice
Your goal is to engage your audience, not put them to sleep. Be animated about your topic. Talk about it as if it was the most interesting thing in the world. Your classmates will thank you for it.

Use hand motions
Move your hands along as you talk, using them to emphasize points and keep the audience interested. It will also channel your nervous energy into a better place.


6. Do not read or read like you mean it


When giving a presentation, from a communication perspective, speaking is always better than reading. However, when you find yourself in the situation where  you are going to read, there are a few techniques you can use to make it more enjoyable for the audience (remember your audience).

Always address the audience, even when reading. Make sure you take your eyes off the paper and look at  the audience. Highlight parts in the text that you wish to stress, e.g. keywords,  signposts, words that evoke, etc.



7. Have a good conclusion

You've probably heard the presentations that end in something like "um... yeah," Your conclusion is your final impression on your audience, including your teacher. Make it exciting by introducing a final statistic, or come up with something creative to do at the end. Your conclusion can be anything so long as your audience knows you're finished.

Tell a story, maybe one with a personal note. Stories are great for history or English presentations. Maybe you can tie your presentation into a little anecdote about a famous historical person?

Ask a provocative question. Ending with a question is a good way of getting your audience to think about your presentation in an interesting way. Is there a certain conclusion you want them to come to? Maybe you can frame a the question in a way that suggests that conclusion.
