6. WhatsApp Messenger is a freeware and cross-platform instant
messaging service for smartphones.[10] It uses the Internet to make voice calls,
one to one video calls; send text messages, images, GIF, videos, documents,
user location, audio files, phone contacts and voice notes[11][12] to other users
using standard cellular mobile numbers. All data are end-to-end encrypted. It
also incorporates a feature called Status, which allows users to upload photos
and videos to a 24-hours-lifetime feed that, by default, are visible to all contacts,
similar to Snapchat, Facebook and Instagram Stories. The client was created by
WhatsApp Inc., based in Mountain View, California, which was acquired
by Facebook in February 2014 for approximately US$19.3 billion.[13][14] By
February 2016, WhatsApp had a user base of over one billion making it the
most popular messaging application at the time

7. HISTORY OF WHATSAPP
 WhatsApp, was incorporated in 2009 by Brian Acton and Jan Koum, both former
employees of Yahoo! . After Koum and Acton left Yahoo! in September 2007, the duo
traveled to South America as a break from work.[18] At one point they applied for jobs at
Facebook but were rejected.[18] For the rest of the following years Koum relied on his
$400,000 savings from Yahoo!. In January 2009, after purchasing an iPhone and realizing
that the App Store would soon create an industry of apps, Koum started visiting his friend
Alex Fishman in West San Jose where the three would discuss ".... having statuses next
to individual names of the people", but this was not possible without an iPhone developer.
Fishman found a Russian developer on RentACoder.com, Igor Solomennikov, and
introduced him to Koum. Koum named the app "WhatsApp" to sound like "what's up". On
February 24, 2009, he incorporated WhatsApp Inc. in California. However, because early
versions of WhatsApp often crashed or got stuck at a particular point, Koum felt like
giving up and looking for a new job, upon which Acton encouraged him to wait for a "few
more months".[18]
 In June 2009, Apple launched push notifications, allowing users to be pinged when they
were not using an app. Koum changed WhatsApp so that when a user's status is
changed, everyone in the user's network would be notified.[18] WhatsApp 2.0 was
released with a messaging component and the number of active users suddenly
increased to 250,000. Acton was still unemployed and managing another startup, and he
decided to join the company.[18] In October 2009, Acton persuaded five former friends in
Yahoo! to invest $250,000 in seed funding, and Acton became a co-founder and was
given a stake. He officially joined on November 1.[18] After months at beta stage, the
application eventually launched in November 2009 exclusively on the App Store for the
iPhone. Koum then hired a friend who lived in Los Angeles, Chris Peiffer, to develop
the BlackBerry version, which arrived two months later.[18]

8. An ad-free instant messaging service for all major smartphones
from WhatsApp Inc., wholly owned by Facebook. Founded in 2009
by Brian Acton and Jan Koum, WhatsApp uses the Internet as an
alternative to the SMS text messaging system. Via Wi-Fi,
subscribers pay nothing for WhatsApp messages the first year and
99 cents per year thereafter. If Wi-Fi is unavailable, and people use
their cellular data plans for WhatsApp messages, thousands can be
sent for a fraction of total usage because text takes up very few
bytes (characters).

14. WHATSAPP PAYMENTS
 WhatsApp Payments is a peer to peer money
transfer feature that is set to launch in India.
WhatsApp has received permission from
the National Payments Corporation of India (NPCI)
to enter into partnership with multiple banks in July,
2017[90] to allow users to make in-app payments
and money transfers using the Unified Payments
Interface (UPI).[91] UPI enables account-to-account
transfers from a mobile app without having any
details of the beneficiary's bank.[92]

15. BUSINESS MODEL
 In response to the Facebook acquisition in 2014, Slate columnist Matthew
Yglesias questioned whether the company's business model of charging
users $1 a year was viable in the United States in the long term. It had
prospered by exploiting a "loophole" in mobile phone carriers' pricing. "Mobile
phone operators aren't really selling consumers some voice service, some
data service, and some SMS service", he explained. "They are selling access
to the network. The different pricing schemes they come up with are just
different ways of trying to maximize the value they extract from
consumers."[144] As part of that, carriers sold SMS separately. That made it
easy for WhatsApp to find a way to replicate SMS using data, and then sell
that to mobile customers for $1 a year. "But if WhatsApp gets big enough,
then carrier strategy is going to change", he predicted.
 On January 18, 2016, WhatsApp's founder Jan Koum announced that the
service would no longer charge their users a $1 annual subscription fee in an
effort to remove a barrier faced by some users who do not have a credit card
to pay for the service.[46][47] He also explained that the app would not display
any third party advertisement and instead would bring new features such as
the ability to communicate with business organizations.[

17. COMPETITION AND SHARES
 WhatsApp competes with a number of Asian-based messaging
services (that as of 2014, were services like We Chat (468 million
active users), Viber (209 million active users[and LINE (170 million
active users)), WhatsApp handled ten billion messages per day in
August 2012, growing from two billion in April 2012,and one billion the
previous October. On June 13, 2013, WhatsApp announced that they
had reached their new daily record by processing 27 billion
messages. According to the Financial Times, WhatsApp "has done
to SMS on mobile phones what Skype did to international calling on
landlines."
 In April 2014, WhatsApp crossed half-a-billion user mark.
 In May 2014, WhatsApp crossed 50 million monthly active users in
India, which is also its largest country by the number of monthly active
users.]
 In October 2014, WhatsApp crossed 70 million monthly active users
in India, which is 10% of its total user base (700 MM).
 In February 2017, WhatsApp crossed 200 million monthly active users
in India.
 As of February 2017, WhatsApp has over 1.2 billion users globally.

19. SECURITY
 On May 20, 2011, an unconfirmed security researcher from the Netherlands
under the pseudonym "WhatsappHack" published, to the Dutch websites
Tweakers.net and GeenStijl, a method by which WhatsApp accounts could
be hijacked. The researcher noticed a flaw in the authentication process,
which allowed the researcher to hijack an account by trying to login with
another phone number and intercepting the verification SMS text message
that, under specific conditions, remained in the outbox of the Symbian phone
after the WhatsApp client would attempt to send it to itself. On Android, the
verification message could be obtained through reading the "radio" with a
tool named "logcat". The researcher would then copy and send the
intercepted verification message to the real number of the phone, using an
SMS gateway to spoof the "sender" phone number to the number the
researcher tried to maliciously login with. This method worked, and
WhatsApp issued a patch within one day after publication of the articles, to
both the Android and Symbian clients. WhatsApp did have a security
mechanism, by design, which would disable the account on the phone of the
original owner of the phone number, when they had a WhatsApp account.[

20. In May 2011, another security hole was reported which left communication
through WhatsApp susceptible to packet analysis. WhatsApp communications
were not encrypted, and data was sent and received in plaintext, meaning
messages could easily be read if packet traces were available.[96]
In May 2012 security researchers noticed that new updates of WhatsApp no
longer sent messages as plaintext,[97][98][99] but the cryptographic method
implemented was subsequently described as "broken".[100][101]In August 2012
the WhatsApp support staff said that messages were encrypted in the "latest
version" of the WhatsApp software for iOS and Android (but not BlackBerry,
Windows Phone, and Symbian), without specifying the cryptographic
method.[102]
On January 6, 2012, an unknown hacker published a website that made it
possible to change the status of an arbitrary WhatsApp user, as long as the
phone number was known. To make it work, it only required a restart of the
app. According to the hacker, it was only one of many security problems in
WhatsApp. On January 9, WhatsApp reported that it had resolved the
problem, although the only measure actually taken was to block the website's
IP address. As a reaction, a Windows tool was made available for download
providing the same functionality. This problem has since been resolved in the
form of an IP address check on currently logged-in sessions

21. German Tech site The H demonstrated how to use WhatsAPI to hijack any
WhatsApp account on September 14, 2012.[105] Shortly after, a legal threat to
WhatsAPI's developers was alleged, characterized by The H as "an apparent
reaction" to security reports, and WhatsAPI's source code was taken down for
some days.[106] The WhatsAPI team has since returned to active
development.[107]
On December 1, 2014, Indrajeet Bhuyan and Saurav Kar, both 17 years old,
demonstrated the WhatsApp Message Handler Vulnerability, which allows
anyone to remotely crash WhatsApp just by sending a specially crafted
message of 2kb in size. To escape the problem, the user who receives the
specially crafted message has to delete his/her whole conversation and start a
fresh chat, because opening the message keeps on crashing WhatsApp unless
the chat is deleted completely.[108] In early 2015, after WhatsApp launched a
web client that can be used from the browser, Bhuyan also found that it had two
security issues that compromised user privacy: the WhatsApp Photo Privacy
Bug and the WhatsApp Web Photo Sync Bug.[109][110]
On March 2, 2016, WhatsApp introduced its document-sharing feature, initially
allowing users to share PDF files with their contacts.[111] However, WhatsApp's
default state of automatically downloading attachments raised some concerns
in the press about risk and security once support for document sharing
expanded beyond PDF files.[112]

22. PRIVACY
 A major privacy and security problem has been the subject of a joint
Canadian-Dutch government investigation. The primary concern was
that WhatsApp required users to upload their mobile phone's entire
address book to WhatsApp servers so that WhatsApp could discover
who, among the users' contacts, was available via WhatsApp. While
this was a fast and convenient way to quickly find and connect the
user with contacts who were also using WhatsApp, it meant that their
address book was then mirrored on the WhatsApp servers, including
contact information for contacts who were not using WhatsApp. This
information, which consisted solely of phone numbers without any
additional information such as the name of the contact, was stored
in hashed, though not salted, form.[120][121][122][123] Late 2015, the Dutch
government released a press-statement claiming that WhatsApp had
changed its hashing method, making it much harder to reverse, and
thus now fully complies with all rules and regulations.[124]
 A user does not need to send a friend request to send messages to
another user, due to the contact discovery mentioned above

23. In August 2016, WhatsApp announced that it will start sharing account
information with Facebook, consisting of the phone number of the account
owner and aggregated analytical data. The address books and metadata of
users are not shared. According to WhatsApp, this account information is
shared to "track basic metrics about how often people use our services and
better fight spam on WhatsApp. And by connecting your phone number with
Facebook's systems, Facebook can offer better friend suggestions and show
you more relevant ads if you have an account with them." This means that
Facebook can target advertisements on the Facebook Platform better by
making links between users based on the phone numbers, and make "friend
suggestions" to its users based on WhatsApp's data. User data will not be
shared with advertisers, and is only used internally on the Facebook services.
WhatsApp emphasizes the content of user messages is still kept private thanks
to its end-to-end encryption, which means WhatsApp cannot read the content of
chats.[127][128] However, users are given the choice to opt out of sharing this data
with Facebook for advertisement purposes.[129] In October 2016, Article 29
Working Party stated that it has serious concerns regarding the manner in
which the information relating to the updated Terms of Service and Privacy
Policy was provided to users and consequently about the validity of the users’
consent.[

24. TERRORISM
 In December 2015, it was reported that Islamic State terrorists had
been using WhatsApp to plot the November 2015 Paris
attacks.[117] ISIL also uses WhatsApp to traffic sex slaves.[citation needed]
 In March 2017, U.K. Secretary of State Amber Rudd said encryption
capabilities of messaging tools like WhatsApp are unacceptable, as
news reported that Khalid Masood used the application several
minutes before perpetrating the 2017 Westminster attack. Rudd
publicly called for police and intelligence agencies to be given access
to WhatsApp and other encrypted messaging services to prevent
future terror attacks.[118]
 In April 2017, the perpetrator of the Stockholm attack reportedly used
WhatsApp to exchange messages with an ISIS supporter shortly
before and after the 2017 Stockholm attack. The messages involved
discussing how to make an explosive device and a confession of the
perpetration the attack

27. CHARACTERISTICS OF ENGLISH LEARNING
USING WHATSAPP
 It is collaborative
 It provides varieties of learning materials
 It enables learners to develop four main skills of
language
 It promotes 3 way communication
 It strengthens students self confidence

28. CONCLUSION
 WhatsApp has become a popular application for social
networking around the world where people are
exchanging their personal and business related
information. “According to the Financial Times,
WhatsApp has done to SMS on mobile phones what
Skype did to international calling on landlines.”
WhatsApp has gained rapid increase of usage in terms
of a social networking application. The number of
downloads for WhatsApp on Android, exceeds one
hundred million. Now, WhatsApp application became top
five free applications among thirty other communication
applications in Google Play.
