The increasing digitization of modern society has led to a growing volume of digital information---such as emails, photos, videos, and electronic records---being presented as evidence in legal proceedings. However, traditional storage systems are costly, slow, and prone to server failures. To address these challenges, we propose a system leveraging blockchain and IPFS to store electronic evidence securely and reliably. Existing Layer 1 blockchain-based systems face three key limitations: (1) scalability issues with slow throughput and high costs under heavy traffic; (2) privacy risks due to public visibility of transaction data; and (3) impracticality of on-chain storage for large evidentiar...

Skin cancer has become a serious public health issue worldwide. The number of cases is rising due to higher UV exposure and changing lifestyle patterns. Early detection is the best way to save lives. However, many areas still lack specialized doctors and equipment needed for a quick diagnosis. In this paper, we develop and test an automated skin cancer detection method based on standard smartphone photography. It provides a practical solution for resource-limited settings by removing the need for expensive clinical dermoscopy equipment, making diagnosis accessible in areas with limited infrastructure. The system was trained and tested on PAD-UFES-20, which contains 2,298 clinical smartphone... More >

As data ecosystems become more diverse and time-critical, traditional monolithic ETL pipelines face challenges to meet the demands of modern data engineering workloads in terms of scalability, adaptability, and operational resilience. In this paper, we introduce an event-driven microservices approach to orchestrate and deploy AI-based ETL (ETL = Extraction, Transformation, and Loading) pipelines in a Kubernetes-managed environment that includes the following components: asynchronous orchestration using Apache Kafka, hybrid anomaly detection, adaptive schema inference, and predictive load balancing. The proposed architecture breaks the ETL processing into loosely coupled services, which can b... More >
