Detection of diseases based on electrocardiography and electroencephalography s...
Ponciano, Vasco Rafael Gaspar; Pires, Ivan M.; Ribeiro, Fernando Reinaldo; Villasana, María Vanessa; Garcia, Nuno M.; Leithardt, ValderiNowadays, cardiac and brain disorders are dispersed over the world, where an early detection allows the treatment and prevention of other related healthcare problems. Technologically, this detection is difficult to perform, and the use of technology and artificial intelligence techniques may automate the accurate detection of different diseases. This paper presents the research on the different techniques and p...
PRICHAIN: A Partially Decentralized Implementation of UbiPri Middleware Using B...
Sestrem Ochôa, Iago; Silva, Luis; Mello, Gabriel de; Silva, Bruno Alves da; De Paz, Juan F.; Villarrubia Gonzalez, Gabriel; Garcia, Nuno M.With the popularization of the Internet-of-Things, various applications have emerged to make life easier. These applications generate a large amount of user data. Analyzing the data obtained from these applications, one can infer personal information about each user. Considering this, it is clear that ensuring privacy in this type of application is essential. To guarantee privacy various solutions exist, one of...
PRISEC: Comparison of Symmetric Key Algorithms for IoT Devices
Saraiva, Daniel; Leithardt, Valderi; Paula, Diandre De; Mendes, André Sales; Villarrubia Gonzalez, Gabriel; Crocker, Paul AndrewWith the growing number of heterogeneous resource-constrained devices connected to the Internet, it becomes increasingly challenging to secure the privacy and protection of data. Strong but efficient cryptography solutions must be employed to deal with this problem, along with methods to standardize secure communications between these devices. The PRISEC module of the UbiPri middleware has this goal. In this wo...
Multi-device Notifications: a comparison between MQTT and CoAP
Silva, Luis; Mello, Gabriel de; Silva, Bruno Alves da; Villarrubia Gonzalez, Gabriel; Santana, Juan da Paz; Prata, Paula; Leithardt, ValderiNew devices generate, send, and display messages about their status, data retrieval, and device information. An increase in the number of notifications received, tends to reduce their tolerance . This article sets out a notification management system focused on user profiles and environments. The solution involves transferring notifications in a multi-device scenario using MQTT and CoAP technologies, while also...
