RT info:eu-repo/semantics/article T1 Using the Metadata-Based App-PI Ecosystem to Assess the Privacy Impact of Health Apps A1 Martínez González, María Mercedes A1 Pérez de la Fuente, Alejandro A1 Aparicio De La Fuente, Amador A1 Criado-Lozano, Pablo A. K1 privacidad, ciberseguridad K1 Privacy, Metadata, Mobile apps, Health apps, IoE AB Mobile applications (apps) facilitate the management ofdevices and sensors from mobile devices in IoE environments. However,their use carries risks for the privacy of their users: many of them managepersonal data. The App-PI (App Privacy Impact) ecosystem analyzes theimpact of apps on privacy, addressing the challenge of knowing, under-standing and mitigating these risks.In App-PI, a metadata warehouse, a set of analysis tools that calcu-late indicators, a visualization platform, and verification processes, col-laborate. Data flows between these components to provide persons usingthe visualization platform with accurate, reliable, and understandableinformation. The warehouse hosts metadata related to the privacy andsecurity of mobile apps. The data flow starts with the collection andintegration of data hosted in the warehouse. The analysis tools use thesedata to calculate indicators that provide objective measures of the riskassociated with each app. These values are the input for a verificationprocess based on static analysis, which provides confidence. To make iteasier for end users to understand these indicators, they are displayedon the visualization platform with easy-to-understand charts. The flowsand usefulness of this ecosystem are shown for health and wellness apps,characteristic of IoE environments.
