Research on Security Enhancement and Personalized Configuration of Printing Services Based on Blockchain Technology

Constrained by a centralized architecture, traditional printing systems have significant deficiencies in security, efficiency, and personalized services. This study proposes an intelligent printing system based on blockchain technology. By leveraging a two-factor authentication mechanism, a dynamic risk scoring model, and a personalized configuration generation strategy driven by smart contracts, it is committed to enhancing the security and improving the efficiency of printing services. Experimental verification shows that, compared with traditional solutions, this system performs remarkably well in key indicators such as authentication delay (only 127 ms), configuration matching degree (up to 82%), and user satisfaction (4.2/5). It has opened up a new model for printing services to move towards intelligence and security.
