Shadow profile
Shadow profile describes the situation when users' or non-users' information is collected without their consent. The most discussed case of shadow profiling is on Facebook, which is reported to collect information on people which they did not provide. Shadow profile's history. Early in 2012, a data breach of over six million Facebook users' personal information indicated the existence of shadow profiles, since the leaked information was not provided by users themselves. After this, Facebook started to combine user's shadow profiles with their public profiles. The combined profiles were then further shared with the users' friends  if they used Facebook's Download Your Information (DYI) tool. Shadow profile and major firms. Shadow profile and Facebook. Facebook has been collecting the personal information of its users for years without consent. Specific information that Facebook obtained without users' permission included offsite email addresses and phone numbers, which Facebook could then use to match with existing profiles. Once the incident broke out, there was an increasing number of people who became outraged due to privacy concerns. According to comments on Facebook blogs and some other community websites such as Hacker News, we see that some people were surprised or  even angry when they found out Facebook owned information that they never gave. Users were also wondering why Facebook would own their private information. According to Facebook, users should be aware of the data collection , but there was no specific feedback for matching people's information. The Chief Executive Officer of Facebook, Mark Zuckerberg, denied knowing about shadow profiles. Based on Facebook's responses to ZDNet, a business technology news website, it would take "precise and coincidental timing" for a malicious person to use the DIY tool with intent and obtain Facebook's combined (shadow profile) data on a targeted  user. Shadow profile and Google. While Google's mission is to provide worldwide information and make it accessible to all the people, it has been collecting data which exceeds users' comprehension. It is promised under Google's terms such that it will not disclose the full extent of users' information that they collect. Nevertheless, according to an Android smartphone's result it shows that Google has been keeping shadow profiles from the users. One of the instances is that, Google's "My Activity" page omits much of the data that Google collects and only shows certain history; the omitted data , in this case, would be users' shadow profile. Shadow profile's influence. Positive influences. The influences brought by shadow profile can be perceived from a two-sided perspective: positive and negative. Benefits brought by shadow profile related behaviors include a more efficient way of data collection and anomaly behaviors detection. Some other researches show that integrated conceptualizations of Internet Privacy Concerns (IPC) have several implications: the third-order factor of IPC can differentiate the relation between IPC and other constructions and allows both website users and managers to analyze the importance of various privacy contexts. Negative influences. Possible harms to  users from privacy and information leakage include collection of sensitive data like financial account numbers, health information and precise geolocation. In the 21st century, the workplace is one of the most quintessential social establishments where employees perform in a given and defined condition and there starts to emerge a blurred line between workspace and personal space. Even when people knowingly share their thoughts online through comments or likes, their traces can affect real live events such as recruiting decisions due to the surveillance conducted by employers. Possible privacy issue factors. Some argue that users are aware of the possible privacy  invasion, the potential benefits and risks while utilizing social media. However, researches show that users upload a large amount of personal information into online space. Some researchers describe this phenomenon as users' lax attitude, and possible explanations for this behaviors are a combination of high gratification, usage patterns, and a psychological mechanism similar to third-person effect. Users themselves are sometimes found as the reason of information leakage. To generate more customized results, sometimes users are willing to share their information with Internet of Things (IoTs) for their own convenience. Other circumstances that users would share their information is when  they feel anxious, concerned, or being able to protect themselves from privacy invasion, the more likely they will conduct privacy protection behavior. In other words, when users feel no control over privacy invasion, they are less likely to protect their information. There are also researchers argue that there is a correlation between information leakage and companies' cooperation with third-parties. Online platforms would need to find a balance between the monetization with third-parties and managing users' private information, and a study shows that higher privacy concerns from users would drive up publisher websites’ decision making and third party market  structures, such that higher privacy concerns lead to higher industry concentration. Even more, different situations and environmental factors while conducting online behaviors are highly likely to influence people's behaviors, and may lead to rational/irrational decision makings. In terms of protection from the officials, by drawing reference to case law on Article 8 of the European Convention on Human Rights, some researchers conclude that the current law cannot adequately address the issue of privacy nor provide protection for open source. Possible privacy issue solutions. To address the issue of leaking personal information there exist multiple facets. One category  of the solution suggests focus on users. One of the argued solutions points out the inefficiency of privacy terms that companies use to ask for users' consent, such that they are sometimes too lengthy (Facebook's privacy terms has 9,500 words), involved with professional vocabularies that only few would fully understand or the users do not understand who are the other parties they are granting their information to. As a result, one of the solutions is to advance the privacy terms by making them easy to read and understand. In addition, the conversation among users is another factor that leads  to information leakage such that people share their information with each other but they become incapable of controlling over the spread of that information afterwards. Thus some argue that instead of focusing on what companies can do to provide a clearer picture of the possible information access, users themselves should be the primary target of controlling over their personal information online and this would work as an efficient way to ease both companies' and consumers' concerns with data collection. Another proposed argument also emphasizes the focus on users, which claims that by making users fully aware of what they are  doing online and the logistics behind online behaviors, they will put more trust into the virtual world and would take care of their personal information even more. Instead of merely focusing on users, some other suggest the interdependent relationship between users and online platforms or companies, and the social contract between them: while companies collect personal data and feedback from users, users would be benefited from the modified functional improvements. As a result, as companies are not merely the side notifying users about the privacy norms but being a contractor responsible for maintaining a mutually beneficial relationship with users, the  privacy tension is eased.
