<p>As a carrier of cultural dissemination, digital cultural and creative products are confronted with numerous challenges in their digital and networked development, including data copyright protection, user privacy protection, and content security. The traditional design methods of cultural and creative products not only have the problems of high energy consumption and low interactivity, but also are difficult to meet the users’ demands for security and personalized experience in the modern digital environment. The research is based on gradient-aware transmission technology to achieve highly sensitive user behavior capture and low-energy consumption data transmission. Utilize image segmentation and reconstruction technology to achieve personalized product design and intelligent content display. Introduce cutting-edge digital security technologies such as quantum encryption and blockchain to build a secure and reliable data transmission and copyright protection mechanism. Verify the system performance through experiments and optimize the energy management strategy. Experimental data show that, compared with traditional design methods, the system proposed in this paper has lower energy consumption and higher user interaction frequency in terms of interaction performance and energy consumption control. In terms of digital security, quantum encryption technology ensures the unbreakability of data transmission, while blockchain technology enables the immutability and traceability of copyright information, effectively protecting user privacy and product Copyrights. The system provides new ideas for the sustainable development of the cultural and creative industry and opens up new paths for the design and promotion of cultural and creative products in the digital age.</p>
