All about internet privacy n cyber world !!!

2. INTRODUCTION
 As people use computers for a variety
of purposes, confidential
information, confidential
communications, and personal
choices can be registered in a variety
of ways.
 Internet privacy is a broad term
referring to the various
concerns, technologies, and strategies
for protecting
information, communications, and
choices that are meant to be private.

3.  If you choose to shop online, use
social networking sites, play online
games, or participate in
forums, Internet privacy can become
an issue in a number of ways.
 If your passwords are exposed, your
identity can be fraudulently used or
even stolen.
 If your contact information is passed
around, you may be subject to spam.

4.  If your browsing history becomes
public, people will know what you’ve
been looking at online.
 Fortunately, taking certain precautions
can reduce the privacy risks that you
face.

5.  Strong passwords that are kept secret
are one way to safeguard
your Internet privacy.
 The strongest passwords have certain
characteristics: they have no personal
information, they don’t use real
words, they combine upper and
lowercase characters with numbers, and
they are at least eight characters long.
 It is important to note, however, that the
strongest password does no good if
someone else can access it.

6.  Browser privacy settings, which
control elements like storage of your
browsing and download history and
the acceptance of cookies, are there
for you to alter to meet your
preferences
 Similarly, social networking sites have
settings to allow you to control the
level of privacy of various postings you
may make.

7.  Note that the default settings may be
skewed towards the public exposure
of information rather than towards
Internet privacy.
 Facebook has been criticized on this
point.

8.  For some sites , make sure you read
the privacy terms before signing up. In
that, your main choice usually is to
become a participant, often with
an email address attached to your
user name, which may or may not be
your real name.
 As an alternative, you may be able to
take advantage of guest privileges, if
they are offered, or be limited to
reading, but not posting.

9.  Accidental violation
of Internet privacy can also occur.
 This would be the case if somebody
accidentally or unthinkingly forwarded an
email to multiple parties that was only
meant for one person, or neglected to
omit a personal comment from the
sender before resending.
 Though this can best be avoided by
rigorously separating work and personal
emails, this is not always a practical
solution. Careful attention and discretion
are the only real safeguards.

10. Internet privacy: why it is
important

creative users.

21. Types of Internet security
 Network layer security
 Ipsec protocol
 Biometric security

22. Network layer security
 IP can be made secure with the help
of cryptographic methods and
protocols that have been developed
for securing communications on the
Internet.

23. Ipsec protocol
 This protocol is designed to protect
communication in a secure manner
using IP.
 It is a set of security extensions
developed by IETF, and it provides
security and authentication at the IP
layer by using cryptography.

24.  To protect the content, the data is
transformed using encryption
techniques.
 There are two main types of
transformation that form the basis of
IPsec:
 the Authentication Header (AH) and
Encapsulating Security Payload
(ESP).

25. Biometric security
 Biometrics (or biometric
authentication) refers to the
identification of humans by their
characteristics or traits.
 Computer science, biometrics to be

identification and access control.
