Privacy Issues

Lack of Privacy Tools to protect user data
– Only basic access control
– Profile public or private
– Privacy setting interface is Complex

Weak Privacy Policy
• Privacy policy – a disclaimer about using user‘s personal information
– Do Social Sites respect its privacy policy?
– Policies can change anytime!
– Uploaded content is property of users or the site!!
– Can you really delete your profile?
![Page 9: Privacy Issues with Social Networking Sites](https://reader036.vdocuments.net/reader036/viewer/2022062314/568148ab550346895db5bcf6/html5/thumbnails/9.jpg)
Privacy Framework
• Role: Foundation to address privacy issues
– Categorize user data, user privacy concerns and profile viewers
– Adapt privacy levels - based on these categorizations
– Adapt Tracking level
![Page 10: Privacy Issues with Social Networking Sites](https://reader036.vdocuments.net/reader036/viewer/2022062314/568148ab550346895db5bcf6/html5/thumbnails/10.jpg)
User data• Categorize user profile information into the following
groups:
– Identity - determine physically who is the user
– Demographic profile- age, gender, weight, race, political view….
– Activity - lists all the activities that users perform• Adding new friends• Commenting on profile• Change in personal information
– Social Network • Relationship status
– User friends – User subscribed groups
– Added content - blog, photos, music or video clips

User privacy concern
• Classify data to be shared as a privacy concern
– Healthy data – • General information about users
– Nick name– Hobbies, – Landscape photos
– Harmless data - User’s demographic profile
– Harmful data – • Inappropriate photos• Blog entry that may damage the user’s reputation
– Poisonous data - Sensitive information that may cause Security risks

Profile Viewers
• Best Friends – Trustworthy, can share all information
• Good Friends – Real life friends, can share more information
• Casual Friends - Based on similar interest, limited information share
• Visitors - could be users or non-users of the SNS, not in friend’s List
Group people who can see the profile based on intimacy and trust

Privacy levels
• Based on Profile Viewers, four levels of privacy
![Page 14: Privacy Issues with Social Networking Sites](https://reader036.vdocuments.net/reader036/viewer/2022062314/568148ab550346895db5bcf6/html5/thumbnails/14.jpg)
![Page 15: Privacy Issues with Social Networking Sites](https://reader036.vdocuments.net/reader036/viewer/2022062314/568148ab550346895db5bcf6/html5/thumbnails/15.jpg)
Tracking levels• Strong tracking - User does not mind being tracked on
SNS
• Weak tracking – User minds if his/her profile is tagged to friends profile
• No tracking – No name, no tags, no photos in friends list

Privacy Protection based on User Type
![Page 18: Privacy Issues with Social Networking Sites](https://reader036.vdocuments.net/reader036/viewer/2022062314/568148ab550346895db5bcf6/html5/thumbnails/18.jpg)
Conclusions
• Existing solutions do not protect user privacy totally
• Lack of user awareness
• Privacy comes with a price
• Need for Privacy tools – strong and easy to use
• Need for Legal Law Enforcement to protect privacy
