Secure data management

More about the book

Information and communication technologies are advancing rapidly, with processing speeds and digital storage capacities increasing significantly. The Internet and wireless technologies enable global communication with just a few clicks. These developments hold the potential to transform daily life through concepts like ubiquitous computing and ambient intelligence. Technology is becoming omnipresent in the form of smart, sensitive computing devices that operate transparently, collecting and processing user information to function intelligently and adaptively. However, these advancements raise new challenges in security and data management. With data accessible anytime and anywhere, unauthorized access becomes easier, leading to heightened privacy concerns. The ability to collect, store, and search personal information poses risks to individual privacy. Consequently, research in secure data management is increasingly vital, drawing interest from both data management and security research communities. Key issues include traditional topics like access control and database security, as well as emerging areas such as privacy protection and cryptographically enforced access control.
