  4. Why is privacy important? • Your data is valuable to companies • If the product is free, YOU are the product! • Social relationships are not flat! • There’s no UNDO button • Once its out, it stays out • Who’s looking at you? • Administrative officials, co-workers, students? • HR researches prospective candidates • Obscurity is NOT security!

  5. “Being Found” – Methods of Location • Oversharing is common • Google Searches (with logical operators) • Ex: “Trevor Nelson” AND “Bradley University” OR “Galesburg High School” OR “2009” • People Search Engines • Spokeo.com, whitepages.com • Social Media Search • Username Checkers • Namechk.com

  6. Namechk.com

  7. Being Found • Cyber stalking • The act of using the internet to aggressively tail someone against their will • Cyber stalkers love location services! • Facebook “check-ins”, Location-based Tweets, Foursquare, Google Location • People may maliciously attempt to use information against you based on beliefs or words

  8. Facebook – Best Practices • Build Lists • Friends, Acquaintances, Family, Professionals • Create your OWN lists, don’t use defaults • Don’t accept all friend requests! • Set profile to “Friends Only” • Turn off search engine indexing • Remove unused apps • Name obfuscation? (Personal preference) • Obscure your profile picture • Unlike irrelevant pages, leave old groups

  9. Facebook Best Practices Cont’d. • Disable Instant Personalization • Disallow using your likeness in ads • Disallow third party sites from using you in ads • Set Review tagged posts before allowing them to ON • Disclaimer: This does not REMOVE the tag from the original poster, just from your own wall. • Edit your profile, define limits of who sees what (have you made your lists?) • And of course, watch what you post!

  10. Facebook Best Practices Cont’d • View your profile through the eyes of others:

  11. Review settings • Look things over carefully and often:

  12. Bad “app”les

  13. Limit your audience

  14. Twitter Best practices • Do not use your full name! • Use an ambiguous photo • Do not link your account to untrusted websites • News comments, untrusted apps, sites requiring a sign-in • Protect your Tweets • Disable location tagging • Does everyone need to know where you are at every moment?

  15. Twitter best practices

  16. What about other sites? • Major services outside of Facebook and Twitter • LinkedIn, Foursquare, Yelp, Instagram, Vine • Use your best judgment, assume everything is public • The LinkedIn Problem • By its nature, you want your resume-related information visible • Avoid connecting to Facebook in any way!

  17. Reduce your online “footprint” • Footprint is defined as your online presence • Number of social profiles, appearances on websites and searches, “searchability” • Hide these profiles from Google! • If you cannot do that… • CHANGE information such as names, locations, education, workplace • Delete old profiles • Are you seriously using MySpace?

  18. General security tips • Set good passwords • Avoid dictionary words and personal information: your first/last name, birthday, hometown • Most common passwords: 123456, password, cats, music etc. • Do not trust everything! Apps especially • If it sounds too good to be true, it is • Safe apps will not spam friends lists when you use them • Never give out a password! No service will ask for your password directly • Do not connect to open Wi-Fi • Like broadcasting your information on the radio • Use HTTPS / Encryption
