Internet privacy is important to protect personal information, communications, and choices shared online. Taking precautions like using strong passwords, adjusting privacy settings, and being aware of privacy policies can help safeguard privacy. Security measures at the network layer, like IPsec protocols, and biometric authentication, also help enhance online privacy and security.

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
 Teens and young adults are the most
creative users.
 Personal information :
Name, Address, etc…
 Technology increases risk.
 28th jan 2008 celebrates Data privacy
day.

decide who has to access to your
personal information.

12. You can’t get something for
nothing

 Use of https.
 Double security standards.
 Use of strong passwords.

16. Privacy policy should provide
 Notice
 Choice
 Access
 Security

17. Security risks
 Passwords
 File sharing
 Spyware
 Phishing
 Updating

18. solutions…..
 cookie control
 anti virus software
 firewalls
 encryption tools

19. Two absolute choices

20. Security for privacy
 Internet security is a branch of
internet privacy specifically related to
the Internet often involving browser
security
 The Internet represents an insecure
channel for exchanging information
leading to a high risk of intrusion or
fraud, such as phishing.

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
specific, is used as a form of
identification and access control.

26. Forms or types…
 Palm check
 Retina check
 Heartbeat and pulse rate
 Finger tips check
 Voice commands
 Imagination (under construction)

27. conclusions….
 Internet privacy can be provided upto
a limit.
 Awareness should be increased.
 Privacy tips should be adopted by net
users.
 latest technology enhances security
like cloud computing.
