A Blockchain Framework for Patient-Centered Health Records and Exchange (HealthChain): Evaluation and Proof-of-Concept Study

Background: Blockchain has the potential to disrupt the current modes of patient data access, accumulation, contribution, exchange, and control. Using interoperability standards, smart contracts, and cryptographic identities, patients can securely exchange data with providers and regulate access. The resulting comprehensive, longitudinal medical records can significantly improve the cost and quality of patient care for individuals and populations alike. Objective: This work presents HealthChain, a novel patient-centered blockchain framework. The intent is to bolster patient engagement, data curation, and regulated dissemination of accumulated information in a secure, interoperable environment. A mixed-block blockchain is proposed to support immutable logging and redactable patient blocks. Patient data are generated and exchanged through Health Level-7 Fast Healthcare Interoperability Resources, allowing seamless transfer with compliant systems. In addition, patients receive cryptographic identities in the form of public and private key pairs. Public keys are stored in the blockchain and are suitable for securing and verifying transactions. Furthermore, the envisaged system uses proxy re-encryption (PRE) to share information through revocable, smart contracts, ensuring the preservation of privacy and confidentiality. Finally, several PRE improvements are offered to enhance performance and security. Methods: The framework was formulated to address key barriers to blockchain adoption in health care, namely, information security, interoperability, data integrity, identity validation, and scalability. It supports 16 configurations through the manipulation of 4 modes. An open-source, proof-of-concept tool was developed to evaluate the performance of the novel patient block components and system configurations. To demonstrate the utility of the proposed framework and evaluate resource consumption, extensive testing was performed on each of the 16 configurations over a variety of scenarios involving a variable number of existing and imported records. Results: The results indicate several clear high-performing, low-bandwidth configurations, although they are not the strongest cryptographically. Of the strongest models, one’s anticipated cumulative record size is shown to influence the selection. Although the most efficient algorithm is ultimately user specific, Advanced Encryption Standard–encrypted data with static keys, incremental server storage, and no additional server-side encryption are the fastest and least bandwidth intensive, whereas proxy re-encrypted data with dynamic keys, incremental server storage, and additional server-side encryption are the best performing of the strongest configurations. Conclusions: Blockchain is a potent and viable technology for patient-centered access to and exchange of health information. By integrating a structured, interoperable design with patient-accumulated and generated data shared through smart contracts into a universally accessible blockchain, HealthChain presents patients and providers with access to consistent and comprehensive medical records. Challenges addressed include data security, interoperability, block storage, and patient-administered data access, with several configurations emerging for further consideration regarding speed and security

Malware Pattern of Life Analysis

Many malware classifications include viruses, worms, trojans, ransomware, bots, adware, spyware, rootkits, file-less downloaders, malvertising, and many more. Each type may share unique behavioral characteristics with its methods of operations (MO), a pattern of behavior so distinctive that it could be recognized as having the same creator. The research shows the extraction of malware methods of operation using the step-by-step process of Artificial-Based Intelligence (ABI) with built-in Density-based spatial clustering of applications with noise (DBSCAN) machine learning to quantify the actions for their similarities, differences, baseline behaviors, and anomalies. The collected data of the research is from the ransomware sample repositories of Malware Bazaar and Virus Share, totaling 1300 live malicious codes ingested into the CAPEv2 malware sandbox, allowing the capture of traces of static, dynamic, and network behavior features. The ransomware features have shown significant activity of varying identified functions used in encryption, file application programming interface (API), and network function calls. During the machine learning categorization phase, there are eight identified clusters that have similar and different features regarding function-call sequencing events and file access manipulation for dropping file notes and writing encryption. Having compared all the clusters using a “supervenn” pictorial diagram, the characteristics of the static and dynamic behavior of the ransomware give the initial baselines for comparison with other variants that may have been added to the collected data for intelligence gathering. The findings provide a novel practical approach for intelligence gathering to address ransomware or any other malware variants’ activity patterns to discern similarities, anomalies, and differences between malware actions under study

Hypatiamat - I want to solve questions about...

Dissertação de mestrado em Informatics EngineeringHypatiamat is a Portuguese project comprised of several applications that aim to develop the Math skills of students from the 1st through 9th grades (Basic Education). The ingraining of mental calculation strategies, numbering systems, and logical operations lead to a better success rate in this subject in later years. One of the project’s components is the online platform (https://www.hypatiamat.com), which aims to foster autonomous learning through more interactive practices due to the current ease of technological access in this age group, by trying to appropriate teaching to everyday life. Several tools are made available, such as videos, tutorials, explanations, questions, etc. on various Math topics that students can easily access at any time. Teachers that aim to enhance their students’ learning process using this digital approach can exercise it in multiple applications provided by the platform, where the interactions are carried out and controlled through these means. The monolithic architecture (written in PHP) has received contributions from multiple developers over the years in order to address the scalability issues introduced with this platform’s growing popularity, which thus far demanded manual efforts for maintenance and content insertion. As such, there has been an incremental process of modernization, turning the various constituent applications into distinct microservices. "I Want to Solve Questions About..." is one of these applications where students are provided with a large selection of questions in the form of mini-games (multiple choice, true or false, ...), regarding the themes mentioned above. The first objective of the dissertation is to develop a back-office that allows the teachers in charge of the project to manage existing questions as well as add new ones for the students, since the current process requires updating the database manually. The second one is the modernization of the application’s interface at the technological level, by making use of adequate frameworks and programming languages and at the user level, by making an effort to maintain the intuitive workflow that led to its popularity but with a modernized design, in order to be consistent with other online tools.O Hypatiamat é um projeto português constituído por várias aplicações que visa desenvolver as aptidões, na disciplina de Matemática, de alunos do 1º ao 9º ano de escolaridade (Educação Básica). O enraizamento de estratégias de cálculo mental, sistemas de numeração e operações lógicas originam uma melhor taxa de sucesso nesta disciplina em anos posteriores. Uma das componentes deste projeto é a plataforma online (https://www.hypatiamat.com), cujo propósito é fomentar a aprendizagem autónoma através de práticas mais interativas, devido à facilidade de acesso tecnológico atual desta faixa etária, tentando apropriar o ensino ao quotidiano. São disponibilizadas várias ferramentas, tais como vídeos, tutoriais, explicações, questões, etc sobre os vários temas da Matemática (Ensino Básico) que os alunos podem facilmente aceder a qualquer momento. Professores que pretendam enriquecer a aprendizagem dos seus alunos com esta metodologia digital podem exercê-lo nas várias aplicações que a plataforma disponibiliza, onde a interação é realizada e controlada através destes meios. A arquitetura monolítica (escrita em PHP) tem recebido contribuições de vários desenvolvedores ao longo dos anos de modo a colmatar os problemas de escalabilidade introduzidos com a popularidade crescente desta plataforma, que até agora exigia esforço manual para manutenção e inserção de conteúdo. Assim, tem existido um processo incremental de modernização, tornando as várias aplicações constituintes em microsserviços distintos. A "Quero resolver questões de..." é uma destas aplicações, onde são disponibilizadas aos alunos várias questões, sob a forma de mini-jogos (escolha múltipla, verdadeiro ou falso, ...), relativas aos temas mencionados anteriormente. O primeiro objetivo da dissertação é o desenvolvimento de um backoffice que permita aos professores responsáveis gerirem as questões existentes assim como adicionarem novas para os alunos, visto que o processo atual obriga a atualização manual na base de dados. O segundo é a modernização da interface da aplicação ao nível: tecnológico, utilizando frameworks e linguagens de programação adequadas ao problema; do utilizador, de modo a manter o fluxo intuitivo que gerou a sua popularidade mas tendo em conta um design mais atualizado para manter a consistência com outras ferramentas online

Collisions: drawing in the digital age

This research outlines the reconfiguration of the creative act of drawing through physical practice as a response to mass culture. This practice takes place in the context of developing digital technologies, culminating in metadrawing. Metadrawing is defined as the integration of the post-digital collapse of media specificity in the visual arts. This research posits metadrawing as a descriptor for the paradigm shift between the physical act of drawing in pre-digital mass culture and the principles of drawing incorporated into digital technologies. Through this shift, drawing has become an artistic act that is no longer working to collapse media divisions, and now operates within and without these divisions, destabilised by digital technologies. This research examines drawing as a history of innovations and responses to shifts in technologies and their applications. Questions of genre, form and medium are subsequently downplayed for an interdisciplinary approach. High and low are no longer distinct, as the internet search engine is adopted into the artist's toolbox, alongside the digital camera and animation software. The many accessible and disposable images are integrated as raw matter, to fossick and sift through. Accompanying studio research operates within the interdisciplinary freedoms of the metadrawing. Approaches to quotation, appropriation, pastiche, irony, detachment and sincerity are explored through a rigorous drawing practice, resulting in a vast, multilayered body of work. This self-reflexive and intuitive practice incorporates numerous ciphers into its many suspended, but interrelated narratives. Beyond the physical level, the work operates on an intertextual level, moving between the metaphysics of genre and previously separated art forms to create a reconfigured history, unhampered by previous distinctions and boundaries of media and form. This research posits the act of drawing as a reaction to, or divergence from, the dominant techno-capitalist status quo, treating the tactile experiences of studio practice as subversive, transgressive, and erotic. This research explores the subjectivity and the subjective agency of the artist. Drawing is therefore defined as a process of unrepeatability, a process that, while no longer necessary for picture making, still forms a crucial and engaging tier of the visual arts. Drawing’s divergence from the commercialised intangibility of the digital has revitalized its practitioners, demanding a reconsideration of what is means to draw today. This tension is explored through the different methods of studio practice, on the level of the personal-biological, the erotic, and in terms of collision and materiality. Specific images are selected through criteria directly linked with the subjective agency of the artist, and reconfigured through artistic practice, creating a new imbrication of the raw image matter
