PrivacyAnalyzer is a generic, cross-vertical Network Application whose functionality is to discover privacy vulnerabilities of network streams of interest. The latter can be streamed from mission-critical services implemented in private networks or streams from other Network Applications. PrivacyAnalyzer’s business goal is to be capitalised as a cross-vertical Network Application providing a generic privacy function integrated with NEF, overall catering to a high-performant (Spark-based) solution for finding privacy vulnerabilities for Network Applications and/or mission-critical 5G slices in privacy networks which require privacy analysis. Within the scope of 5GASP, PrivacyAnalyzer is used to detect (albeit they are encoded; see later the format detector microservice of the backend, which can decode a set of common encodings) privacy-sensitive, geo-related fields within the network messages of Automotive Network Applications.
