Abstract: The invention proposes a personal data processing system (1) comprising a data storage module (12) storing an encrypted reference personal data database, wherein it further comprises a hardware security module (10) storing a private key for decryption of said reference personal data and configured to implement data filtering preventing any output of personal data. The invention further provides a method for processing personal data.

Abstract: An eUICC card comprising an initial runtime environment, subscriber profiles, associated adapters, and an adaptive routine configured to apply these adapters. An adapter enables the initial runtime environment to be adapted to the specificities of the corresponding profile when the latter is enabled. To enable dynamic adaptation of the runtime environment to the profiles used, the eUICC card further comprises inverse adapters associated with the profiles. The inverse adapter of the active profile makes it possible to restore the initial runtime environment upon disabling or deleting this profile. The adaptation can consist of modifying a Java class of the Java Card runtime environment of the eUICC, to the specificities of a profile.
