The field of emerging technologies, including virtual reality, artificial intelligence, and homomorphic encryption, is moving towards a focus on privacy and security. Researchers are exploring new approaches to protect user data and prevent unauthorized access, such as attribute-based encryption and flexible hardware-enabled guarantees. There is also a growing interest in understanding user perceptions of privacy and security, particularly in the context of messaging platforms and extended reality systems. Noteworthy papers in this area include the proposal of a disruptive approach in homomorphic AI, which enables the analysis and processing of data in its cryptographically secure form, and the development of a multimodal anonymization mechanism for extended reality systems, which reduces re-identification rates without compromising usability. Overall, the field is advancing towards more robust and user-centric privacy and security solutions.
