No contexto do combate ao crime, instituições governamentais de vários países instituíram unidades ou setores especializados para atuar em diferentes áreas e expertises como, por exemplo, em atividades de investigação e inteligência. Entretanto, por atuarem em um cenário voltado a atividades restritas, ou que muitas vezes envolvem informações ou ativos sigilosos, surge a necessidade de adoção de soluções alternativas voltadas à gestão, armazenamento e/ou compartilhamento de ativos digitais com a preocupação em segurança da informação. Sendo uma das tecnologias que vem ganhando cada vez mais es...

This writing survey has started by gathering an example of principally peer-inspected sources, and additionally an educational diagram of articles from different channels to give an agent perspective of three essential points.

Der Artikel präsentierte eine Möglichkeit das heutzutage zentral angewandte Machine Learning zum Zweck einer autonomen Fahrweise auf eine Vielzahl an Endgeräten lokal zu verteilen. Zugleich wurden die Herausforderungen des Datenschutzes in Bezug auf personenbezogene Daten im digitalen Wandel der Automobilindustrie unter Einhaltung der EU-DSGVO näher betrachtet. Als Kommunikationsverifizierung zur Sicherung des Modellaustausches eignete sich ein eigens optimiertes Blockchain Framework. Der Nutzen der Kombination der beiden Technologien wurde anhand eines praktischen Anwendungsfalls herausgestel...
