Enhancing privacy on smart contract-enabled blockchains has garnered much attention in recent research. Zero-knowledge proofs (ZKPs) is one of the most popular approaches, however, they fail to provide full expressiveness and fine-grained privacy. To ...

Secret sharing is an essential tool for many distributed applications, including distributed key generation and multiparty computation. For many practical applications, we would like to tolerate network churn, meaning participants can dynamically enter ...

Smart contracts are self-executing programs that run on blockchains (e.g., Ethereum). While security is a key concern for smart contracts, it is unclear how smart contract developers approach security. To help fill this research gap, we conducted a mixed-...

The Workgroup on Interactive Systems in Healthcare (WISH) connects academic and industry researchers across human-computer interaction, medical informatics, health informatics, digital health, and beyond to foster a community around innovations in ...

Early recovery after substance use disorder (SUD) treatment is a period of high risk. The majority of people will relapse, often within weeks of completing treatment. In the modern era, re-entry upon completion of treatment includes both digital and non-...

When a child is hospitalized with a serious illness, their family members must process emotional stress, quickly absorb complicated clinical information, and take on new caregiving tasks. They also have to coordinate with each other and with other ...

When their child is hospitalized, parents take on new caregiving roles, in addition to their existing home and work-related responsibilities. Previous CSCW research has shown how technologies can support caregiving, but more research is needed to ...

This paper proposes a secure decentralized protocol that a consortium of local banks can use to complete a netting process in a privacy-preserving fashion without relying on a single central bank. To do so, it makes use of two key ingredients - ...

When a child is admitted to the hospital with a critical illness, their family must adapt and manage care and stress. HCI and Computer-Supported Cooperative Work (CSCW) technologies have shown the potential for collaborative technologies to support and ...

The intertwined and sometimes contradictory work of managing complex health needs (e.g., discordant, enigmatic, and/or rare conditions) creates many challenges for patients, caregivers, and healthcare providers. While researchers have created ...

During a health crisis, such as the hospitalization of a child with a serious illness, families must adjust and support each other in coordinating care. CSCW researchers have shown the potential for collaborative technologies to enhance social support ...

Online health communities (OHCs) are spaces where people gather for informational and emotional support around specific medical conditions and concerns. Although OHCs are an active and exciting research area that continuously attracts a wide range of ...

Payment channel networks, and the Lightning Network in particular, seem to offer a solution to the lack of scalability and privacy offered by Bitcoin and other blockchain-based cryptocurrencies. Previous research has focused on the scalability, ...

Cyber attacks are an increasing threat to victims ranging from individuals to businesses and nation-states. Underpinning these attacks is an ecosystem of adversaries that compete with each other in profitable nefarious activities such as ...

Chronic Obstructive Pulmonary Disease (COPD) is one of the major pulmonary diseases and a leading cause of morbidity and mortality worldwide. Although there is no cure for COPD, it can be managed by medication and rehabilitation. Therefore, it is ...

Telemental health (TMH) technologies allow for mental health services to be delivered regardless of geolocation or time, and a new wave of mobile app-based TMH resources hold particular promise for engaging the mental health issues associated with teens ...

Getting the right amount of high quality sleep is crucial for overall health and wellbeing, and pervasive and ubiquitous computing technologies have shown promise for allowing individuals to track and manage their sleep quality. However, sleep ...

Robots that tell children stories are becoming common. Given that the practice of parent-child storytelling is part of family culture, it is critical to investigate parental acceptance of storytelling robots. Drawing on technology acceptance models, the ...

Decentralized consensus protocols based on proof-of-work (PoW) mining require nodes to download data linear in the size of the blockchain even if they make use of Simplified Payment Verification (SPV). In this work, we put forth a new ...

Game jams, which are game creation events in which developers design and build a game over a short period of time, have been shown to support participatory, active STEM learning. Game jams have expanded from their origins as physically co-located ...
