“…Privacy is not the protection of all the users' information but the selective purpose-and usage-bound release of information to a defined group of recipients. The users evaluate utility of information release against possible privacy risks (Vervier et al, 2017).…”

Privacy is a major good for users of personalized services such as recommender systems. When applied to the field of health informatics, privacy concerns of users may be amplified, but the possible utility of such services is also high. Despite availability of technologies such as k-anonymity, differential privacy, privacy-aware recommendation, and personalized privacy trade-offs, little research has been conducted on the users' willingness to share health data for usage in such systems. In two conjoint-decision studies (sample size n = 521), we investigate importance and utility of privacy-preserving techniques related to sharing of personal health data for k-anonymity and differential privacy. Users were asked to pick a preferred sharing scenario depending on the recipient of the data, the benefit of sharing data, the type of data, and the parameterized privacy. Users disagreed with sharing data for commercial purposes regarding mental illnesses and with high de-anonymization risks but showed little concern when data is used for scientific purposes and is related to physical illnesses. Suggestions for health recommender system development are derived from the findings.

“…However, when it comes to online privacy, internet users are having difficulty protecting their personal information [ 44 ]. As cybercrime becomes more prevalent, there is an urgent need to educate people about the risks of excessive information sharing, information control, information visibility, and privacy issues [ 45 ]. In today’s rapidly evolving digital environment, user privacy has emerged as a critical issue that must be addressed [ 46 ].…”

Context: The cause of cybercrime phishing threats in Malaysia is a lack of knowledge and awareness of phishing. Objective: The effects of self-efficacy (the ability to gain anti-phishing knowledge) and protection motivation (attitude toward sharing personal information online) on the risk of instant messaging phishing attacks (phishing susceptibility) are investigated in this study. The protection motivation theory (PMT) was tested in the context of attitudes toward sharing personal information online with a view to improving interventions to reduce the risk of phishing victimisation.Methods: Data were collected using non-probability purposive sampling. An online survey of 328 Malaysian active instant messaging users was collected and analysed in SmartPLS version 4.0.8.6 using partial least squares structural equation modelling. Results: The results showed that a person’s cognitive factor (either high or low self-efficacy) affected their chance of being a victim of instant message phishing. A higher level of self-efficacy and a negative attitude towards sharing personal information online were significant predictors of phishing susceptibility. A negative attitude towards sharing personal information online mediated the relationship between high levels of self-efficacy and phishing susceptibility. A higher level of self-efficacy led to the formation of negative attitudes among internet users. Attitudes toward the sharing of personal information online are critical because they allow phishing attempts to exist and succeed. Conclusions: The findings give government agencies more information on how to organise anti-phishing campaigns and awareness programmes; awareness and education can improve one’s ability to acquire anti-phishing knowledge (self-efficacy).

“…It is thus critical that users adopt, from an early age, a cybersecurity culture on the Internet. The agreement to a set of cyber hygiene practices in their daily routine may prevent users from being threatened with cyberattacks, and private information leakage, which may bring physical, psychological, and monetary losses [7,8].…”

An Integrated Cybernetic Awareness Strategy to Assess Cybersecurity Attitudes and Behaviours in School Context

Digital exposure to the Internet among the younger generations, notwithstanding their digital abilities, has increased and raised the alarm regarding the need to intensify the education on cybersecurity in schools. Understanding of the human factor and its influence on children, namely their attitudes and behaviors online, is pivotal to reinforce their awareness towards cyberattacks, and to promote their digital citizenship. This paper aims to present an integrated cybersecurity and cyberawareness strategy composed of three major steps: (1) Cybersecurity attitude and behavior assessment, (2) self-diagnosis, and (3) teaching/learning activities. The following contributions are made: Two questionnaires to assess risky attitudes and behaviors regarding cybersecurity; a self-diagnosis to measure students’ skills on cybersecurity; a lesson plan addressing cyberawareness to be applied on Information and Communications Technology (ICT) and citizenship education curricular units. Cybersecurity risky attitudes and behaviors were evaluated in a junior high school population of 164 students attending the sixth and ninth grades. The assessment focused on two main subjects: To identify the attitudes and behaviors that raise the risk on cybersecurity among the participating students; to characterize the acquired students’ cybersecurity and cyberawareness skills. Global and individual scores and the histograms for attitudes and behaviors are presented. The items in which we have observed significant differences between sixth and ninth grades are depicted and quantified by their corresponding p-values obtained through the Mann–Whitney non-parametric test. Regarding the results obtained on the assessment of attitudes and behaviors, although positive, we observed that the attitudes and behaviors in ninth grade students are globally inferior compared to those attained by sixth grade students. The deployed strategy for cyberawareness was applied in a school context; however, the same approach is suitable to be applied in other types of organizations, namely enterprises, healthcare institutions and public sector.
