Due to the rapid development of ICT people use more and more every kind of social networks but do not thinking about privacy issues too much. Social Networks like Facebook, MySpace, Twitter, Orkut, Linked In and so on allow users to publish information about themselves and connect to their friends and colleagues. But some of the private life have to be private because the networks’ companies are collecting the information themselves. This data is exploited by marketers who can now send more personalized messages. Published details of daily life help “identity thieves, scam artists, debt collectors and, stalkers to use the information that people themselves have voluntarily provided in a ways harmful for the owner of the information”. Once posted information is avalable for ever.
The paper includes interesting facts that every minute of the day:
• 100,000 tweets are sent
• 684,478 pieces of content are shared on Facebook
• 2 million search queries are made on Google
• 48 hours of video are uploaded to YouTube
• 47,000 apps are downloaded from the App Store
• 3,600 photos are shared on Instagram
• 571 websites are created
• $272,000 is spent by consumers online (source: AllTwitter)
Types of social network sites are social networking sites (Facebook, Twitter, LinkedIn, Google+, MySpace) social media sharing sites (Photo sharing Instagram, Flickr, Photobucket, Picasa and video sharing Youtube, Vimeo, iMemories, audio sharing SoundCloud, MySpace and etc.) and Location Based Networks (Foursquare, Gowalla, Loopt).
The data can be published very simply – one press of the button – and people do this without thinking about privacy. They do not realize that tomorrow this data is available to everyone (parents, teachers, employers, spouse, criminal or a marketing company). If you publish your private life details you lose control of your personal information and maybe your job, too. Especially teenagers do not understand the risk that their personal information can used by others.
It is good to know that our old data are not replaced but they will stay and everybody can find them. Also if you press “Like” in Facebook the information will be connected with other sites.
Another interesting section of paper: “While U.S. legislators speak out against employers requesting Facebook passwords from employees, the following information — much of it sensitive and potentially damaging — doesn’t require special access to uncover: 4.7 million “liked” a Facebook page about health conditions or treatments (details an insurer might use against you); 4.8 million have used Facebook to say where they planned to go on a certain day (a potential tip-off for burglars); 20.4 million included their birth date, which can be used by identity thieves; 39.3 million identified family members in their profile; 900K discussed finances on their wall; 1.6 million liked a page pertaining to racial or ethnic affiliations; 2.3 million liked a page regarding sexual orientation; 7.7 million liked a page pertaining to a religious affiliation; 2.6 million discussed their recreational use of alcohol on their wall; 4.6 million discussed their love life on their wall.“
There is one more concern: “location based social networks which are made possible by linking Global positioning system (GPS), which track user’s location, to the capabilities of the World Wide Web, along with other vital features such as instant messaging”.
This paper was very interesting and useful, containing facts and examples.
