This document discusses how social media platforms like Facebook and Google generate revenue from users' personal data. It explains that they collect extensive data on users' activities, interests, and demographics which is then used to highly target advertising. Advertisers pay more when ads are better targeted, so the platforms have strong incentives to keep users engaged and responding to ads. Their algorithms aim to show the ads most likely to elicit desired user actions. While free for users, the platforms treat personal data as a commodity to be analyzed and sold for advertising purposes. Some see this business model as transferring too much power and control over personal data from individuals to corporations.

The purpose of this presentation is to present the major industry and consumer trends affecting the hotel industry, specifically with respect to the digital evolution and online booking.
Today, there are 2.8 billion active social media users (+21% YoY), or 37% of the world’s population, compared to 3.8 billion people, or 50% of the world’s population, who are connected to the internet (source: according to GlobalWebIndex).
In 2016, social media continued to experience several changes that require marketers to take notice. The first transition concerns the multitude of social platforms and the rise of chatting apps. The second transition has been changes in mobile and video usage. The third transition involves the integration of social features into online commerce and content websites, or the development of “social core”.
The increasing penetration and use of mobile, has turned messaging apps into an important type of social networks. In 2016, 27% of the population accessed social media from mobile devices – 1.97 billion people. In 2017, 34% of the world’s population, or 2.55 billion people, use social media on their mobile phones (+30% YoY). Messaging apps are very popular among younger users, with Snapchat the most-used social media platform among 12 to 24-years-olds.

Ecochip is ‘ecology on a chip’. 100 mg of BIOSANITIZER Ecochip has the same
capability as 1 acre of natural forest, of using inorganic nutrients(salts) and CO2 as
food and produce eco-resources (food/fuel and oxygen).
Summary: BIOSANITIZER Ecochips (bio-catalyst) help us utilise three pollutants (salts, carbon dioxide and warmth) as free raw materials. BIOSANITIZER makes the salts usable, as nutrients for the plants. Salty water, thus, can be utilised to grow crops that produce food, fuel, etc. Shallow wells, then are used to collect the sweet water. Carbon dioxide from the air also gets sequestered during the process. Economic recession, thus, can be resolved through the creation of eco-jobs using this innovation.
1. System Disturbances: A system disturbance can be defined as any event that causes the frequency and/or voltage of the system to deviate from the normal range of operation. These are caused by incidents such as occurrence of short circuits, generator trips, feeder trips, sudden increase of power output of a generator due to a defect in its control system.
The responses of the healthy machines for such events should be so as to return the system to the normal status as quickly as possible and with as little manual intervention as possible. Therefore, the response of machines is of utmost importance from the point of view of system security and reliability.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

2. Twitter and Facebook
• Why are Twitter and Facebook worth so much?
• How do free services maximise their profits?
• What exactly are they selling?

3. Facebook
reported figures for the 3 months to June 30 2016
• Revenue: $6.347 billion
• Profit (before tax, after $1.462B R&D): $2.766 billion
• 1.71 billion monthly active users
• Market value: > $350 billion
• each user is worth more than $200 to shareholders
and generates $1.62 profit every 3 months

4. Twitter
reported figures for the 3 months to June 30 2016
• Revenue: $602 million
• Loss (before tax, after $178 million R&D): $104 million
• 313 million monthly active users
• Market value: > $12 billion
• each user is worth around $38 to shareholders and
costs $0.33 every 3 months
4
5. Take-over values
• Facebook bought WhatsApp for $16 billion - £19 billion
in 2014, when WhatsApp had 450m active users (it is
now said to have over 1 billion active users)
• Google bought YouTube for $1.6 billion in 2006 when
YouTube had some 12 million active users
• The number of active users is an important factor
explaining the difference between the value of these
companies and the value of their staff, technology, and
other tangible and intangible assets
5
6. Monetisation
turning users into revenue
• Advertisers will pay for access to users, but usually
only if their adverts create some desired user action
• random advertising would be ineffective - they want to
target particular groups of users
• the more effective their advertising is, the more they are
willing to pay
• showing the most profitable adverts to the best targeted
users will maximise profits for advertisers and for the
company selling the access to their users
6
8. Facebook advert targeting
Facebook offers targeting by ….
• Location Reach your customers in the areas where they live
or where they do business with you. Target adverts by country,
county/region, postcode or even the area around your business.
• Demographics Choose the audiences that should see your
adverts by age, gender, interests and even the languages they
speak.
• Interests Choose from hundreds of categories such as music,
films, sport, games, shopping and so much more to help you
find just the right people.
8
9. • Behaviours You know your customers best, and you can find them
based on the things they do – such as shopping behaviour, the type
of phone they use or if they're looking to buy a car or house.
• Connections Reach the people who like your Page or your app –
and reach their friends, too. It's an easy way to find even more
people who may be interested in your business.
• Partner categories These are targeting options provided by third-
party data partners. With Partner Categories, you can reach people
based on offline behaviours people take outside Facebook, such as
owning a home, being in the market for a new van or being a loyal
purchaser of a specific brand or product. Facebook has partnered
with Acxiom, Epsilon, Experian Marketing Services, Oracle Data
Cloud (formerly Datalogix), and Quantium to activate Partner
Categories in specific markets. These third-party partners collect
and model data from a variety of sources, like public records, loyalty
card programs, surveys and independent data providers.
These descriptions were taken from https://en-gb.facebook.com/business/products/ads/ad-
targeting/ (on 23/8/2016)

10. Facebook charging
Facebook charges by results – an agreed fee for:
• likes
• click-throughs to web pages
• video views
• joining an event
• downloading an advertised app
• … or any other action that Facebook makes available to advertisers
So Facebook’s income depends on showing the right adverts to targeted users
10
11. What adverts will you see?
The ones that maximise the advertiser’s hits and Facebook’s income
• Facebook helps the advertiser to target their audience and to
calculate what it is worth offering for each action by a user.
• Facebook algorithms calculate a Facebook’s value for each
advert, by combining their assessment of the likelihood that the
user will respond, with the fee that the advertiser has bid for their
advert to be displayed
• When a page is accessed, the adverts are then compared in an
auction to determine which adverts are shown on that page
There is a strong incentive for Facebook to keep users online
and responding to advertisements that are well targeted
11
13. Google AdWords
• Google AdWords are a mechanism to target advertisements to people who
are searching for what the advertiser is offering
• When a Google search matches the AdWords the advertiser has purchased,
the advertisement has the chance of being shown near the search results.
13
14. Google AdWords
The advertiser sets the fee they are willing to pay for
each click on their advert (and a daily budget to control
their financial exposure).
A real time ad auction happens with each Google search to
decide which ads will appear for that specific search and
in which order those ads will show on the page.
Each time an Ad Words ad is eligible to appear for a
search, it goes through the ad auction.
The auction determines whether or not the ad actually
shows and in which ad position it will show on the page.
14
15. Google AdWords
Google explains the auction:
• When someone searches, the Ad Words system finds
all ads whose keywords match that search.
• From those ads, the system ignores any that aren't
eligible, like ads that target a different country or
that are disapproved.
• Of the remaining ads, only those with a sufficiently
high Ad Rank may show. Ad Rank is a
combination of your bid, ad quality and the expected
impact of extensions and other ad formats.
15
16. Google uses personal data to
target adverts, including …
Things that you search for (remember how revealing the AOL
search histories were that we looked at in my Big Data lecture)
Websites that you visit
Videos that you watch
Ads that you click on or tap
Your location
Device information
IP address and cookie data
16
17. … and other data you have provided
• Your address, date of birth and gender
• Emails that you send and receive on Gmail
• Contacts that you add
• Calendar events
• Photos and videos that you upload
• Docs, Sheets and Slides on Google Drive
17
18. Google tells users that it analyses
emails and other uploaded content
Our automated systems analyze your
content (including emails) to provide you
personally relevant product features, such as
customized search results, tailored
advertising, and spam and malware
detection. This analysis occurs as the
content is sent, received, and when it is
stored.
18
19. … and uses the data to target advertisements
We try to show you useful ads by using data collected
from your devices, including your searches and
location, websites and apps that you have used, videos
and ads that you have seen and personal information
that you have given us, such as your age range, gender
and topics of interest.
If you are signed in, and depending on your Ads
Settings, this data informs the ads that you see across
your devices. So if you visit a travel website on your
computer at work, you might see ads about airfares to
Paris on your phone later that night.
19
20. How much personal data?
“In 2011, Max Schrems used European data privacy laws to
file a request for his personal data from Facebook. Facebook
provided him with a CD that had 1,222 pages of data
chronicling about 3 years of his use of the service. After
reviewing the data, Schrems discovered that Facebook had
retained deleted chat conversations, event invitations he
did not respond to, pokes, and details on his physical
location identified by IP addresses, among other data
which he never agreed to share. And the 1,222 pages only
contained data from 23 out of the 84 categories Facebook
has"
From https://informationactivism.org/en/europe-vs-facebook
Further lawsuit details on http://europe-v-
facebook.org/EN/en.html
20
21. Who owns your personal data?
• Many sites’ Terms and Conditions say that they can use
your personal data in a wide variety of ways
• Getting access to a relative’s data (their documents and
photo library for example) may difficult after their death,
even for executors.
• See: What Happens to My Facebook Profile When I
Die? Legal Issues Around Transmission of Digital
Assets on Death, by Lilian Edwards (University of
Strathclyde Law School) and Edina Harbinja (University
of Strathclyde Law School; University of Hertfordshire).
21
22. Categories include:
• Lifestyle/Culture, News/entertainment, Business/industry, People,
Hobbies/activities, Travel/Places/events, Technology, Education,
Shopping/Fashion, Food/Drink, Sports/Outdoors, Fitness/Wellness.
• Lifestyle/Culture category has many subcategories: Judaism, Rhombus,
Soho, Citrus, Portuguese language, Nobility, Piccadilly, Asia, Society,
Prophets and messengers in Islam, Instant messaging, Universe, Mezzo-
Soprano and many more
• Facebook explains (in outline) why it has decided that each category is
one of your interests
This may be a very tiny fraction of the data held by Facebook about each
user.
22
Some of the data used to target your ads on Facebook
can be seen at facebook.com/ads/preferences
23. Targeting adverts by your Mood
This is apparently from an Apple patent application
23
24. Google’s patent application to track what advertisements you look at
– perhaps using Google Glass or a similar device?
• Pay per gaze advertising need not be limited to on-line advertisements,
but rather can be extended to conventional advertisement media
including billboards, magazines, newspapers, and other forms of
conventional print media. Thus, the gaze tracking system described
herein offers a mechanism to track and bill offline advertisements
in the manner similar to popular online advertisement schemes.
• Furthermore, the inferred emotional state information can be
provided to an advertiser (perhaps for a premium fee) so that the
advertiser can gauge the success of their advertising campaign. For
example, if the advertiser desires to generate a shocking advertisement
to get noticed or a thought provoking advertisement, then the inferred
emotional state information and/or the gazing duration may be valuable
metrics to determine the success of the campaign with real-world
consumers. 24
25. If mood is important to advertisers,
might you be manipulated?
According to the Washington Post, Facebook
“tweaked the newsfeed algorithms of roughly 0.04 percent of Facebook
users, or 698,003 people, for one week in January 2012. During the
experiment, half of those subjects saw fewer positive posts than usual,
while half of them saw fewer negative ones. To evaluate how that change
affected mood, researchers also tracked the number of positive and
negative words in subjects’ status updates during that week-long period.
Put it all together, and you have a pretty clear causal relationship.”
See: Proceedings of the National Academy of Sciences of the United
States of America Experimental evidence of massive-scale emotional
contagion through social networks
25
26. Your Facebook News Feed
• According to a Washington Post experiment, “as
much as 72 percent of the new material your friends
and subscribed pages post never actually shows up
in your News Feed.”
• In a recent study from the University of Illinois, 62.5
percent of participants had no idea Facebook
screened out any posts.
26
28. The Filter Bubble
• Social media sites want users to be happy and to
stay online …
• … so they tailor what you see, to give you more of
what you like and read at length, and less of what
you don’t
• Over time, this shapes what you see, to reflect and
reinforce your views and prejudices
28
29. Does this matter?
• “Eli Pariser used the example of two people who googled the term “BP”.
One received links to investment news about BP while the other received
links to the Deepwater Horizon oil spill, presumably as a result of some
recommendation algorithm.
• This is an insidious problem. Much social research shows that people
prefer to receive information that they agree with instead of information that
challenges their beliefs. This problem is compounded when social networks
recommend content based on what users already like and on what people
similar to them also like.
• This is the filter bubble—being surrounded only by people you like and
content that you agree with.
• And the danger is that it can polarise populations creating potentially
harmful divisions in society.” (from MIT Technology Review)
29
30. How much control can you have?
Some… with a bit of inconvenience. This is what I do:
• All searches use startpage.com which uses Google through
a proxy and offers a proxy link to the resulting websites, so
Google cannot easily link searches to me.
• Firefox browser, set to private browsing (no history is kept
and all cookies cleared after each session) with Ad Blockers
Ghostery and Privacy Badger.
• I disable Javascript using the NoScript plugin and only run
scripts if I trust the website.
Does this seem paranoid? I’m not alone …
30
32. Browsing without Ad Blockers
can be dangerous
• “This morning, we encountered a gratuitous act of violence against Android users. By
simply viewing their favorite news sites over their morning coffee users can end up
downloading a banking Trojan (detected by Kaspersky Lab solutions as Trojan-Banker.AndroidOS.Svpeng.q).
There you are, minding your own business, reading the news and BOOM! – no
additional clicks or following links required. And be careful – it’s still out there.
• It turns out the malicious program is downloaded via the Google AdSense advertising
network. Be warned, lots of sites use this network – not just news sites – to display
targeted advertising to users. Site owners are happy to place advertising like this
because they earn money every time a user clicks on it. But anyone can register their
ad on this network – they just need to pay a fee. And it seems that didn’t deter the
authors of the Svpeng Trojan from pushing their creation via AdSense. The Trojan is
downloaded as soon as a page with the advert is visited.” Kaspersky 15 Aug 2016
Just going to a website with a malicious advert can infect your phone or computer.
32
33. Differential Pricing and
Discrimination
• Do websites offer everyone the same prices?
• Increasingly not. Their algorithms try to assess the maximum you
are willing to pay.
• When you compare prices and go back to the cheapest, why has
that cheap fight or hotel room gone?
• It might have been sold but it’s possible that the website
calculated that you would pay more now.
• Many algorithms are confidential: they may be
discriminating unlawfully, by accident or by design.
33
34. How Much is your Data Worth?
Here is what IT security company Avast Software, says that data
sellers are charging for the following:
• Credit cards without a balance guarantee: $8 per card (number
and CVV
• $2,000 balance guarantee: $20 per card (number and CVV)
• Driver's license scans: $20
• Email addresses and passwords: $0.70–$2.30
• Social Security numbers: $1 ($1.25 for state selection)
• PayPal credentials/access: $1.50
34
35. Conclusions
• Your time and your personal data are valuable to commercial companies
and to criminals and that value is increasing.
• The amount of data they collect and store gives them increasing power:
power to make money, but also power that could be used for other
purposes. Power greater than other media, because of targeting
• Big data analysis provides unprecedented power to address people
individually and personally or as highly selected groups, and to influence
or to discriminate against individuals or groups with impunity, because the
algorithms for big data analysis are usually commercial secrets.
• Free services have to be paid for somehow but, if we are the product
being traded, are free services already too expensive?
