Social profiling

[1] There are various platforms for sharing this information with the proliferation of growing popular social networks, including but not limited to LinkedIn, Google+, Facebook and Twitter.

This is because of too much "noise" generated, which affects the process of information collection due to explosively increasing online data.

The literature showed that user social attributes, including age, gender, home location, wellness, emotion, opinion, relation, influence are still need to be explored.

[8] Social networks provide people access to intimate online interactions; therefore, information access control, information transactions, privacy issues, connections and relationships on social media have become important research fields and are subjects of concern to the public.

A lot of information is voluntarily shared on online social networks, such as photos and updates on life activities (new job, hobbies, etc.).

This is concerning because 39% of users have experienced profiling hacking; 78% burglars have used major social media networks and Google Street-view to select their victims; and an astonishing 54% of burglars attempted to break into empty houses when people posted their status updates and geo-locations.

[10] Like Facebook, Twitter is also a crucial tunnel for users to leak important information, often unconsciously, but able to be accessed and collected by others.

[15] A postdoctoral researcher from the University of Pennsylvania, Daniel Preoţiuc-Pietro and his colleagues were able to categorize 90% of users into corresponding income groups.

Their existing collected data, after being fed into a machine-learning model, generated reliable predictions on the characteristics of each income group.

[10] The advent and universality of social media networks have boosted the role of images and visual information dissemination.

Regardless of one's number of likes for a post, or connections on LinkedIn, social media contains plentiful personal information.

[23] As Klout Score becomes a popular combined-into-one-score method of accessing people's influence, it can be a convenient tool and a biased one at the same time.

A study of how social media followers influence people's judgments done by David Westerman illustrates that possible bias that Klout may contain.

Several suggestions that Kred is giving to the audience about increasing influence are: (1) be generous with your audience, free comfortable sharing content from your friends and tweeting others; (2) join an online community; (3) create and share meaningful content; (4) track your progress online.

The prevalence of the Internet and social media has provided online activists both a new platform for activism, and the most popular tool.

While online activism might stir up great controversy and trend, few people actually participate or sacrifice for relevant events.

[25] A closer examination of their online shared content shows that the most shared information online include five types: The Chinese government hopes to establish a "social-credit system" that aims to score "financial creditworthiness of citizens", social behavior and even political behaviour.

According to Celia Hatton from BBC News, everyone in China will be expected to enroll in a national database that includes and automatically calculates fiscal information, political behavior, social behavior and daily life including minor traffic violations – a single score that evaluates a citizen's trustworthiness.

[28] According to Jake Laband (the deputy director of the Beijing office of the US-China Business Council), low credit scores will "limit eligibility for financing, employment, and Party membership, as well restrict real estate transactions and travel."

However, this has been a great concern for privacy for big companies due to the huge amount of data that will be analyzed by the system.
