AppSentinel is an intelligent anti-malware system for Android app stores, capable of performing static and dynamic analysis of malicious applications from several sources and understanding their characteristics and behavior to infer new malicious patterns. These new patterns are turned into rules used on the testing of applications submitted to the app store, accelerating its response to new threats. Applications are also tested regarding secure mobile development practices, leading to educational feedbacks to developers about their apps’ vulnerabilities. Finally, it performs automatic analysis of users’ feedback to infer the threat level of apps already published on the app store.

TrustChain consists of reputation systems for consumers and publishers of apps, and an intelligent decision support system for quality assurance and cybersecurity. Based on the reputation of these players, the goal is to increase considerably the efficiency of the app store quality and security services (allowing to focus more in specific apps and trusting more in others). Moreover, the knowledge base related to the reputation is decentralized using blockchain technologies, in order to be possible its adoption and contribution from several app stores, thus generating a global app economy with increased security, trust and transparency.

AppRecommender focuses on offering the right app to the right user at the right time, optimizing thus the current app distribution and discovery services. To do so, the main technologies proposed are a fusion-based recommender system and a semantic search engine. The project aims to have specific impact on the mobile app consumers, mobile app publishers and on the app store. For consumers, the impact will be on the ease of use, efficiency and satisfaction in the discovery of apps, because of the improved alignment between their needs, characteristics and context with the apps offered. For developers, the impact will be on the improved proximity to their target audience, optimizing the user acquisition and retention, and inherently the commercial success. For Aptoide, the impact will be on the optimized quality of service provided to consumers and companies, and in the consequent increase of the number of apps submitted to the store, active users and revenue.
