Summary The social site gathers far more information and uses them to laser-focus the advertisements that appear on each person's page by other companies. “Mining and analyzing these big new data sets can open the door to marketing and for this reason this information could be used for other purposes, accelerating productivity and economic growth.” Applying data mining to those data sets will help to discover new businesses and predict consumer behavior and market shifts.” e.g. Google, Foursquare, etc. but at the same time it is important to understand the limits of privacy

Why Interesting? As data miners, our tasks are colliding with these concerns. It is important to know the privacy of the data that we are collecting for the specific analysis. To know how the data will be used to the ultimate advantage of the people whose personal information is captured in the database. Be sensitive to these worries when collecting or using data, or else we risk burdensome and counter- productive regulation. Some organizations have created the role of chief privacy officer to oversee the protection and use of data.

Relationship With Course Relevant to chapters of Data Mining and Data Warehousing. New application or societal impact of database techniques we learn. The use of data mining for marketing purposes.
