A study on privacy and security aspects of personalised apps

This paper studies personalised smart apps, from a data protection and security point of view. More precisely, having as a reference model the provisions stemming from the General Data Protection Regulation, we investigate whether such apps, whose philosophy is based on the provision of personalised services, adopt appropriate data protection techniques, focusing especially on aspects from the data protection by design and by default principles, as well as on their security features. Our analysis over ten popular such Android apps illustrates the existence of several privacy concerns, including the facts that several data processes are by default enabled without requesting users’ consent, as well as that several data processes are not well justified or sufficiently transparent to the users. Moreover, interestingly enough, the apps studied are not free of known security weaknesses.
