Abstract: Aggressive urbanization increases waste exponentially, causing environmental damage. Reusing them can solve this problem. Our machine learning and blockchain-based system identifies waste products and suggests multiple “Do-It-Yourself” (DIY) recycling and reuse ideas. Blockchain’s shared…
Abstract: Health information exchange improves outcomes and cuts medical costs. Health information exchange requires data integrity and self-determination. Blockchain and dynamic consents solve this. HealthPocket is a blockchain-based mobile platform that uses HL7 FHIR standards…
Abstract: Remote sensing, early warning systems, and visual tracking use small aerial object detection. Existing moving object detection methods can distinguish normal-sized objects from the dynamic background, but not small ones. A novel method is…
Abstract: Online education and meetings have increased during the COVID-19 pandemic. Traditional online environments offer simple streaming services using cameras and microphones, which limits physical expression and real-world cultural and economic activities. Metaverse environments, avatar-based…
Abstract: Patients see multiple doctors, and their health data is shared. Blockchain-based health information systems are ideal for distributed health data and decentralized healthcare systems. For example, a patient is referred to a hospital by…
Abstract: This paper proposed a cross-domain self-authentication scheme to address the “information isolated island” and “redundant registration” problems of user identities in servers for Autonomous Valet Parking (AVP). Decentralized anonymous authentication reduces the authentication center’s…
Abstract: Names and ages are valuable data for modern information systems. Identity management helps users manage and use their digital identities when using online services. A blockchain-based self-sovereign identity (SSI) system promotes peer-to-peer service authentication…
Abstract: Decentralization is necessary when trust and performance cannot depend on one organization. DLTs and DHTs are useful for transactional events and large-scale data storage, respectively. These two technologies can solve many problems. Cryptographic signatures…
Abstract: Cloud firewalls protect Virtual Private Infrastructure from DDoS attacks. Performance models are needed to fully characterize the cloud firewall operation and gain actionable insights into cloud security design. This article proposes a multi-dimensional Continuous-Time…
Abstract: Communication channels and data embedding schemes determine covert communication quality. Bitcoin is popular for covert communication. The consensus mechanism requires participants to spread their valid blocks under an adjustable difficulty, creating a stable periodic…
Abstract: Big data is becoming smart data as IoT devices and traffic explode, helping data scientists understand human behavior through mobility and resource use in public spaces. Smart data markets predict crimes and COVID-19 outbreaks….
Abstract: Remote sensing imagery faces large-scale change, uncertain direction, and high density when detecting and localizing multiclass objects. Remote sensing images benefit from context information. This letter proposes a context-driven detection network (CDD-Net) to improve…
