Established concepts (e.g., 2D authentication schemes) are vulnerable to observation attacks, and most alternatives are relatively slow. We present RubikAuth, an authentication scheme for VR where users authenticate quickly and secure by selecting digits from a virtual 3D cube that leverages coordinated 3D manipulation and pointing. We report on results from three studies comparing how pointing using eye gaze, head pose, and controller tapping impact RubikAuth’s usability, memorability, and observation resistance under three realistic threat models. We found that entering a four-symbol RubikAuth password is fast: 1.69–3.5 s using controller tapping, 2.35–4.68 s using head pose and 2.39 –4.92 s using eye gaze, and highly resilient to observations: 96–99.55% of observation attacks were unsuccessful. RubikAuth also has a large theoretical password space: 45n for an n-symbols password. Our work underlines the importance of considering novel but realistic threat models beyond standard one-time attacks to fully assess the observation-resistance of authentication schemes. We conclude with an in-depth discussion of authentication systems for VR and outline five learned lessons for designing and evaluating authentication schemes.","PeriodicalId":322583,"journal":{"name":"ACM Transactions on Computer-Human Interaction (TOCHI)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123583825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our novel approach is a feature extraction technique that allows us to select meaningful features indicative of depressive symptoms from longitudinal data. It allows us to detect the presence of post-semester depressive symptoms with an accuracy of 85.7% and change in symptom severity with an accuracy of 85.4%. It also predicts these outcomes with an accuracy of >80%, 11–15 weeks before the end of the semester, allowing ample time for pre-emptive interventions. Our work has significant implications for the detection of health outcomes using longitudinal behavioral data and limited ground truth. By detecting change and predicting symptoms several weeks before their onset, our work also has implications for preventing depression.","PeriodicalId":322583,"journal":{"name":"ACM Transactions on Computer-Human Interaction (TOCHI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124839523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Renaud","doi":"10.1145/3429888","DOIUrl":"https://doi.org/10.1145/3429888","url":null,"abstract":"Nudging is a promising approach, in terms of influencing people to make advisable choices in a range of domains, including cybersecurity. However, the processes underlying the concept and the nudge’s effectiveness in different contexts, and in the long term, are still poorly understood. Our research thus first reviewed the nudge concept and differentiated it from other interventions before applying it to the cybersecurity area. We then carried out an empirical study to assess the effectiveness of three different nudge-related interventions on four types of cybersecurity-specific decisions. Our study demonstrated that the combination of a simple nudge and information provision, termed a “hybrid nudge,” was at least as, and in some decision contexts even more effective in encouraging secure choices as the simple nudge on its own. This indicates that the inclusion of information when deploying a nudge, thereby increasing the intervention’s transparency, does not necessarily diminish its effectiveness. A follow-up study explored the educational and long-term impact of our tested nudge interventions to encourage secure choices. The results indicate that the impact of the initial nudges, of all kinds, did not endure. We conclude by discussing our findings and their implications for research and practice.","PeriodicalId":322583,"journal":{"name":"ACM Transactions on Computer-Human Interaction (TOCHI)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131182164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current techniques that couple wireless transmission with touch detection suffer from the problem of selectivity and security, i.e., they cannot ensure communication only through direct touch and not through close proximity. We present BodyWire-HCI, which utilizes the human body as a wire-like communication channel, to enable human–computer interaction, that for the first time, demonstrates selective and physically secure communication strictly during touch. The signal leakage out of the body is minimized by utilizing a novel, low frequency Electro-QuasiStatic Human Body Communication (EQS-HBC) technique that enables interaction strictly when there is a conductive communication path between the transmitter and receiver through the human body. Design techniques such as capacitive termination and voltage mode operation are used to minimize the human body channel loss to operate at low frequencies and enable EQS-HBC. The demonstrations highlight the impact of BodyWire-HCI in enabling new human–machine interaction modalities for variety of application scenarios such as secure authentication (e.g., opening a door and pairing a smart device) and information exchange (e.g., payment, image, medical data, and personal profile transfer) through touch (https://www.youtube.com/watch?v=Uwrig2XQIH8).","PeriodicalId":322583,"journal":{"name":"ACM Transactions on Computer-Human Interaction (TOCHI)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128703695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, these voice assistants offer new opportunities to different populations, including individuals who are not interested or able to use traditional computing devices such as computers and smartphones. To understand how older adults who use technology infrequently perceive and use these voice assistants, we conducted a 3-week field deployment of the Amazon Echo Dot in the homes of seven older adults. While some types of usage dropped over the 3-week period (e.g., playing music), we observed consistent usage for finding online information. Given that much of this information was health-related, this finding emphasizes the need to revisit concerns about credibility of information with this new interaction medium. Although features to support memory (e.g., setting timers, reminders) were initially perceived as useful, the actual usage was unexpectedly low due to reliability concerns. We discuss how these findings apply to other user groups along with design implications and recommendations for future work on voice-user interfaces.","PeriodicalId":322583,"journal":{"name":"ACM Transactions on Computer-Human Interaction (TOCHI)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126466311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
