The Qur’an is probably the most self-referential text in the history of world religions. It often describes its own textuality, it reflects on Arabic as its linguistic medium, it distances itself from other genres of mantic speech such as poetry or soothsaying, it justifies itself vis-a-vis other revelations, and finally it contains important elements of exegesis. Muslim scripture is a message and at the same time often a message about the message. The self-reflexive mood of the Qur’an has only recently become a focus of Qur’anic studies. This collection of papers by a number of experts in the field outlines the role of selfreferentiality for the inner history of Qur’anic recitation, for the canonization of the Qur’anic text and for a better understanding of Qur’anic revelation in its historical embedding.

Web systems are now essential to the daily lives of billions, with social features being crucial for success in today’s digital landscape. Users are increasingly encouraged to share personal data for an enhanced experience, yet the security of these systems is alarmingly inadequate given the volume of sensitive information collected. Threat reports reveal that social media platforms are prime targets for attacks, leading to significant consequences that extend beyond individual users and fueling a thriving black market for stolen data. To address these security challenges in managing personal data, this dissertation proposes a solution architecture alongside three key research contributions. The architecture serves as a foundation for more secure personal data management, while the research contributions offer complementary strategies to protect against unauthorized data disclosure, tampering, and misuse. These components are designed for seamless integration, enhancing both quality and maintainability. The dissertation concludes by discussing evaluation results and outlining potential future work in this critical area of information security.
