ENGR/CS 101 CS Session Lecture 18 No computers today Today is the - - PowerPoint PPT Presentation

ENGR/CS 101 CS Session Lecture 18

 No computers today  Today is the last day for the CS session for this

• group. Mingle during classtime on Friday. No

class on Monday; no final exam.

 Good news, those that submitted Homework 3

by 10pm yesterday have earned an A or A- for the CS session which is 1/3 of the grade for ENGR/CS 101. :-) Hopefully the rest will do so,

• too. Graded programs will be available at the

mingle on Friday.

Lecture 18 ENGR/CS 101 Computer Science Session 1

Outline

 Anonymity vs Privacy  The Internet and Privacy  Rutgers University Social Networking PSA  Social Networking and Privacy  The Cloud and Privacy

Lecture 18 ENGR/CS 101 Computer Science Session 2

Anonymity vs. Privacy

 On-line anonymity: identity is not known  Pros and cons of anonymous access?  Most people really want privacy: private

information is not associated with identity.

 E.g., Right to vote without fear of public judgment.

 When might private information need to be

made public?

Lecture 18 ENGR/CS 101 Computer Science Session 3

Internet and Privacy

 Basically, there is no privacy (or anonymity).

Posting on a public website is like writing on a public wall.

 At the very least, IP address usually is recorded.  More information, if logged in.

 Worse, the 'Net never forgets. Once the bits

go out, someone will have made a copy. You can never find and delete all copies. This includes pictures, responses to postings, etc.

Internet and Privacy

 Conclusion: Don't post anything you wouldn't

want everyone else to know about you now

• r in the future.

Rutgers Social Networking PSA

 What about social networking sites?  Rutgers University made a PSA about

social networking

 What are the points being made by this PSA?  Why do you think Rutgers University thinks it is

necessary to show this PSA to all incoming freshmen?

Social Networking and Privacy

 How many are on Facebook? I positively

identified 16 out of 22. I now know things like Frannie was a lifeguard, Elizabeth was 2014 Girls Tennis State runner up, and Aldo plays the guitar.

 Do your "friends" write messages to your

wall/timeline or post pictures that have you tagged? What happens if I become one of their friends?

Facebook Terms of Use

 For content that is covered by intellectual property rights,

like photos and videos (IP content), you specifically give us the following permission, subject to your privacy and application settings: you grant us a non-exclusive, transferable, sub-licensable, royalty-free, worldwide license to use any IP content that you post on or in connection with Facebook (IP License). This IP License ends when you delete your IP content or your account unless your content has been shared with others, and they have not deleted it.

 I.e., they can do anything they want with your

information.

Lecture 18 ENGR/CS 101 Computer Science Session 8

Facebook Terms of Use

 Information that is always publicly available

 Name  Profile pictures and cover photos  Networks – to show who you may share info  Gender  Username and user ID

 Anything you designate "Public" also is

accessible to APIs and in public search engines

Lecture 18 ENGR/CS 101 Computer Science Session 9

Social Networking and Privacy

 Companies now scour social media sites as

part of background checks.

 Employers ask for passwords as a term of

employment.

 Can they really do this?  Conclusion: Be very careful about what you

post and share on social media sites.

Lecture 18 ENGR/CS 101 Computer Science Session 10

The "Cloud" and Privacy

 What about cloud and other on-line services?  Cloud and other on-line services are just

computers controlled by other people. Some are less secure than others.

 Celebrity nude photos

 Hacked file storage on Apple iCloud backup

servers

 Note that the file transfers were automatic.
