Adolescents' privacy concerns and information disclosure online: The role of parents and the Internet

This study investigated the role of parents and the Internet in adolescents' online privacy concerns and information disclosing behaviors. Specifically, instructive and restrictive parental mediation, adolescents' self-disclosure to parents about their Internet experiences, time spent on the Internet, and participation in online communication activities were examined as factors that may impact adolescents' concerns about online privacy, willingness to disclose personally identifiable information, and actual disclosure of personal information online. A survey conducted in Singapore with 746 adolescents aged 12–18 revealed that instructive parental mediation based on parent-adolescent communication was more effective than restrictive parental mediation based on rule-making and controlling in reducing information disclosure among adolescents. Adolescents' self-disclosure to parents about their Internet experiences was found to be positively associated with their privacy concerns but did not foster privacy protection behaviors. While online chatting had a positive relationship with privacy concerns, excessive use of the Internet and frequent participation in social networking and online gaming resulted in increased information disclosure.     

Health information privacy concerns,antecedents, and information disclosure intention in online health communities

This study explores the antecedents and consequences of health information privacy concerns in online health communities by integrating the dual calculus and protection motivation theories. On the basis of survey data from 337 users, health information privacy concerns, together with informational and emotional support, significantly influence personal health information (PHI) disclosure intention. Privacy concerns are negatively influenced by two coping appraisals (i.e., response efficacy and self-efficacy) and positively affected by two threat appraisals (i.e., perceived vulnerability and perceived severity). The perceived health status differentially moderates the effects of privacy concerns and informational support on the PHI disclosure intention.     

Revealing the relationship between rational fatalism and the online privacy paradox

Previous research has revealed the privacy paradox, which suggests that despite concern about their online privacy, people still reveal a large amount of personal information and don’t take measures to protect personal privacy online. Using data from a national-wide survey, this study takes a psychological approach and uses the rational fatalism theory to explain the privacy paradox on the Internet and the social networking sites (SNSs). The rational fatalism theory argues that risks will become rational if the person believes he or she has no control over the outcome. Our results support the rational fatalism view. We found that people with higher levels of fatalistic belief about technologies and business are less likely to protect their privacy on the Internet in general, and the SNS in particular. Moreover, such relationship is stronger among young Internet users compared with older users.     

Solving the privacy paradox: A counter-argument experimental approach

This study investigates why ordinary online users highly concerned about the misuse of personal information do not adopt privacy-protective behaviors, or even engage in risky behaviors, on the Internet. Given that people have few chances to directly experience privacy infringement and tend to be unfamiliar with technical terms, their opinions as reflected in conventional polls tend to be instantaneous reactions to survey questionnaires, lacking thoughtfulness. By adopting a counterargument experimental technique, this study produced three important findings: (1) people’s opinions about online privacy are swayed after being presented with a message containing a counterargument; (2) this persuasion effect is pronounced among people with a low level of online knowledge or who assess the presented message’s argument as strong; and (3) the privacy paradox is found in conventional polls but disappears in counterargument conditions. These findings imply that opinions concerning online privacy should not be estimated through conventional polling. Rather, alternative polls (e.g., deliberative polls) should be adopted for online privacy policy-making.     

The effect of online privacy policy on consumer privacy concern and trust

This study aims to investigate trust and privacy concerns related to the willingness to provide personal information online under the influence of cross-cultural effects. This study investigated the relationships among the content of online privacy statements, consumer trust, privacy concerns, and the moderating effect of different cultural backgrounds of the respondents. In specific, this study developed a proposed model based on Privacy–Trust–Behavioral Intention model. Further, a total of 500 participants participated in the survey, including 250 from Russia and 250 from Taiwan. The findings indicate a significant relationship between the content of privacy policies and privacy concern/trust; willingness to provide personal information and privacy concern/trust; privacy concern and trust. The cross-cultural effect on the relationships between the content of privacy policies and privacy concern/trust was also found significant.     

The key role of relevance in personalized advertisement: Examining its impact on perceptions of privacy invasion,self-awareness,and continuous use intentions

Internet advertising has become increasingly personalized as advertisers tailor content to individual users. However, this has led consumers to be concerned about their privacy. Based on rational choice theory and self-awareness theory, the current research explores the role of relevance in personalized advertisements and examines its impact on perceptions of privacy invasion, self-awareness, and subsequent continuous use intentions of personalized advertising. Analysis of survey data from 386 online users found that although privacy invasion perceptions are negatively related to continuous use intentions, perceived advertisement relevance mitigates consumer's privacy concerns. Perceived relevance was also found to be positively related to consumer's continuous use intentions through the mediation of self-awareness. This research identifies and highlights the importance of relevance in the tension between privacy concerns and personalized advertisements.     

Do men and women differ in privacy? Gendered privacy and (in)equality in the Internet

This paper investigates how personal privacy behavior and confidence differ by gender, focusing on the dimensions of online privacy data protection and release. A hierarchical regression analysis of cross-sectional survey of a national sample (n = 419) revealed that men and women differed on the level of privacy protection; however, gender had no direct effect on the extent to which data release was exercised. Additionally, gender had a positive association with confidence in privacy protection, but not in the dimension of release. Our study suggests that the gender may affect subjective well-being of online privacy and potentially exacerbate the disparity rooted in socialization of gender. Implications of the findings are discussed in light of Internet access, skill and effort required for building and maintaining privacy, and the important role played by gender in indicating the need for gender-sensitive policy awareness.     

Building online trust through privacy practices

This study applies Mayer et al. [24] trust model to an Internet context. A model is presented linking privacy policy, through trustworthiness, to online trust, and then to customers’ loyalty and their willingness to provide truthful information. The model is tested using a sample of 269 responses. The findings suggest that consumers’ trust in a company is closely linked with the perception of the company’s respect for customer privacy. Trust in turn is linked to increased customer loyalty that can be manifested through increased purchases, openness to trying new products, and willingness to participate in programs that use additional personal information.     

Affect,cognition and reward: Predictors of privacy protection online

This article examined the interplay between cognition and affect in Internet uses for privacy control. A survey of a national sample was conducted to empirically test the relationship between affective concern for and cognitive knowledge of information privacy online. We also tested for the interactive role of reward-seeking as a moderator among these relationships. Findings revealed that concern did not directly play a meaningful role in guiding users’ protective behavior, whereas knowledge was found significant in moderating the role of concern. The interactive role of reward-seeking seems particularly salient in shaping the structure of the relationships. These findings suggest that the intersections between knowledge, reward, and concern can play out differently, depending on the levels of each. Policy implications in relation to users’ cognitive, affective, and reward-seeking rationalities are offered, and future research considerations are discussed.     

Control your Facebook: An analysis of online privacy literacy

For an effective and responsible communication on social network sites (SNSs) users must decide between withholding and disclosing personal information. For this so-called privacy regulation, users need to have the respective skills—in other words, they need to have online privacy literacy. In this study, we discuss factors that potentially contribute to and result from online privacy literacy. In an online questionnaire with 630 Facebook users, we found that people who spend more time on Facebook and who have changed their privacy settings more frequently reported to have more online privacy literacy. People with more online privacy literacy, in turn, felt more secure on Facebook and implemented more social privacy settings. A mediation analysis showed that time spend on Facebook and experience with privacy regulation did not per se increase safety and privacy behavior directly, stressing the importance of online privacy literacy as a mediator to a safe and privacy-enhancing online behavior. We conclude that Internet experience leads to more online privacy literacy, which fosters a more cautious privacy behavior on SNSs.     

Internet social network communities: Risk taking,trust, and privacy concerns

Individuals communicate and form relationships through Internet social networking websites such as Facebook and MySpace. We study risk taking, trust, and privacy concerns with regard to social networking websites among 205 college students using both reliable scales and behavior. Individuals with profiles on social networking websites have greater risk taking attitudes than those who do not; greater risk taking attitudes exist among men than women. Facebook has a greater sense of trust than MySpace. General privacy concerns and identity information disclosure concerns are of greater concern to women than men. Greater percentages of men than women display their phone numbers and home addresses on social networking websites. Social networking websites should inform potential users that risk taking and privacy concerns are potentially relevant and important concerns before individuals sign-up and create social networking websites.     

An Extended Privacy Calculus Model for SNSs: Analyzing Self‐Disclosure and Self‐Withdrawal in a Representative U.S. Sample

The privacy calculus established that online self‐disclosures are based on a cost‐benefit tradeoff. For the context of SNSs, however, the privacy calculus still needs further support as most studies consist of small student samples and analyze self‐disclosure only, excluding self‐withdrawal (e.g., the deletion of posts), which is essential in SNS contexts. Thus, this study used a U.S. representative sample to test the privacy calculus' generalizability and extend its theoretical framework by including both self‐withdrawal behaviors and privacy self‐efficacy. Results confirmed the extended privacy calculus model. Moreover, both privacy concerns and privacy self‐efficacy positively predicted use of self‐withdrawal. With regard to predicting self‐disclosure in SNSs, benefits outweighed privacy concerns; regarding self‐withdrawal, privacy concerns outweighed both privacy self‐efficacy and benefits.

Examining the impact of privacy, trust and risk perceptions beyond monetary transactions: An integrated model

Much interest in privacy and trust studies is about shopping, but privacy research in other forms of online activities is beginning to emerge. This study examined the antecedents of privacy, trust and risk as well as their joint effect on two similar but fundamentally different activities: online transactions and retrieval of privileged information. Both activities involve the delivery of private user information, but the latter gives some leeway for users to control (or even falsify) their true identity. User shopping experience in the present study moderated the relationships and strengths of constructs. The effect of Internet literacy, social awareness and disposition to trust on privacy concern and trust was weaker for experienced shoppers. Privacy concern, trust and risk assessment played a lesser role on the two activity variables for those who were more experienced. Perceived privacy risk stood out as a strong antecedent for respondents in both experience groups, but the effect of Internet literacy, social awareness and disposition on trust was statistically insignificant for the same group. Further practical and managerial implications are provided.     

A bumpy ride on the information superhighway: Exploring turbulence online

Managing our personal information is becoming increasingly complex as people share more and more about themselves and others online. Beyond the ordinary challenges people face in disclosing information in face-to-face settings, the Internet presents additional demands users must take into account related to the size and diversity of their audience as well as the longevity and accessibility of their communication. Using survey data from a diverse group of young adults, this paper explores turbulence online, that is, the breakdown of privacy expectations that result in information spreading beyond a user’s desired audience. More than a third of these young adults reported at least one turbulent encounter online ranging in tangible consequences like ending a friendship or trouble at work or school to emotional trouble like feelings of embarrassment or betrayal. Results suggest that successful privacy management online requires a combination of social and technological skills and behaviors. Findings also bring to light new questions on self- versus other-generated turbulence and broader implications for researchers, designers, and users.     

Understanding online behavioural advertising: User knowledge,privacy concerns and online coping behaviour in Europe

Online behavioural advertising (OBA) is a special form of targeted advertising. For OBA, it is necessary to collect data about online surfing behaviour, which is usually undertaken by installing ‘cookies’. The use of cookies is heavily debated by policy makers in the US and Europe. Central to this discussion is whether users should provide informed consent prior to the installation of cookies. However, to provide informed consent, it is vital that website users understand the mechanisms of OBA and cookies. This study investigates whether the existing knowledge is sufficient, whether website users are concerned about their privacy, and how they cope with OBA, cookies and the requested informed consent. An online questionnaire (N = 2022) was fielded briefly after new European cookie regulations were enacted. The results confirmed that the knowledge is still insufficient to obtain good understanding of this new advertising technique. In addition, the results showed that groups of Internet users did not differ in terms of knowledge, although they did differ in terms of privacy concerns. A comparison of privacy-concerned groups showed that a dual approach is needed in communicating about OBA, not only to inform but also to reduce worries, especially in older and less-educated groups.     

A hybrid solution for privacy preserving medical data sharing in the cloud environment

Storing and sharing of medical data in the cloud environment, where computing resources including storage is provided by a third party service provider, raise serious concern of individual privacy for the adoption of cloud computing technologies. Existing privacy protection researches can be classified into three categories, i.e., privacy by policy, privacy by statistics, and privacy by cryptography. However, the privacy concerns and data utilization requirements on different parts of the medical data may be quite different. The solution for medical dataset sharing in the cloud should support multiple data accessing paradigms with different privacy strengths. The statistics or cryptography technology alone cannot enforce the multiple privacy demands, which blocks their application in the real-world cloud. This paper proposes a practical solution for privacy preserving medical record sharing for cloud computing. Based on the classification of the attributes of medical records, we use vertical partition of medical dataset to achieve the consideration of different parts of medical data with different privacy concerns. It mainly includes four components, i.e., (1) vertical data partition for medical data publishing, (2) data merging for medical dataset accessing, (3) integrity checking, and (4) hybrid search across plaintext and ciphertext, where the statistical analysis and cryptography are innovatively combined together to provide multiple paradigms of balance between medical data utilization and privacy protection. A prototype system for the large scale medical data access and sharing is implemented. Extensive experiments show the effectiveness of our proposed solution.     

Online self-disclosure: The privacy paradox explained as a temporally discounted balance between concerns and rewards

Technological innovations are increasingly helping people expand their social capital through online networks by offering new opportunities for sharing personal information. Online social networks are perceived to provide individuals new benefits and have led to a surge of personal data uploaded, stored, and shared. While privacy concerns are a major issue for many users of social networking sites, studies have shown that their information disclosing behavior does not align with their concerns. This gap between behavior and concern is called the privacy paradox. Several theories have been explored to explain this, but with inconsistent and incomplete results. This study investigates the paradox using a construal level theory lens. We show how a privacy breach, not yet experienced and psychologically distant, has less weight in everyday choices than more concrete and psychologically-near social networking activities and discuss the implications for research and practice.     

An experimental economics approach toward quantifying online privacy choices

The importance of personal privacy to Internet users has been extensively researched using a variety of survey techniques. The limitations of survey research are well-known and exist in part because there are no positive or negative consequences to responses provided by survey participants. Such limitations are the motivation for this work. Experimental economics is widely accepted by economists and others as an investigative technique that can provide measures of economic choice-making that are substantially more accurate than those provided by surveys. This paper describes our efforts at applying the techniques of experimental economics to provide a foundation for (a) estimating the values that consumers place on privacy and various forms of security (encryption, HIPAA, etc.) and for (b) quantifying user responses to changes in the Internet environment. The contribution of this study is a better understanding of individual decision-making in the context of benefits and costs of making private information available to Internet sites. Preliminary results from a series of pilot studies are consistent with optimizing behaviors, indicating that continued application of experimental economics techniques in the quantification of Internet user actions in privacy/security space will be illuminating. Our results show that Internet users place great value on security measures, both regulatory and technical, that make identity theft much less likely. Our Web-based experiments indicate that privacy- and security- enhancing protections are likely to be subject to moral hazard responses, as participants in our online experiments became more aggressive in their Internet usage with greater protection in place.

Internet users’ perceptions of ‘privacy concerns’ and ‘privacy actions’

A consistent finding reported in online privacy research is that an overwhelming majority of people are ‘concerned’ about their privacy when they use the Internet. Therefore, it is important to understand the discourse of Internet users’ privacy concerns, and any actions they take to guard against these concerns. A Dynamic Interviewing Programme (DIP) was employed in order to survey users of an instant messaging ICQ (‘I seek you’) client using both closed and open question formats. Analysis of 530 respondents’ data illustrates the importance of establishing users’ privacy concerns and the reasoning behind these concerns. Results indicate that Internet users are concerned about a wider range of privacy issues than surveys have typically covered. The results do not provide final definitions for the areas of online privacy, but provide information that is useful to gain a better understanding of privacy concerns and actions.
