Informatics-Enabled Digital Watermarking for BIM Service Systems: Robustness under Geometric Attacks

Building Information Model (BIM) is an important source of measurement data and results, which is widely used in construction and urban planning.AI driven security can improve the availability of BIM and make model data easier to store.However, as more and more illegal piracy incidents become more and more urgent, the need for BIM copyright protection becomes more and more urgent.Signing security agreements or hiring professional institutions and agents can only limit people's behavior, completely rely on people's subjective activities, and is not conducive to the security of BIM data.Therefore, this paper analyzed the characteristics, application environment and problems of BIM, and analyzed the attack methods and technical characteristics of digital watermarking algorithm.Enhancing watermark robustness directly supports logistics service continuity by preventing data loss during inter-organizational handovers and protecting construction sequencing information.The improved resistance to geometric attacks ensures the reliability of shared service models among designers, contractors, and operators throughout the complex supply chain.This study grounds the evaluation in information security theory and service system reliability frameworks to address the critical need for data integrity in construction logistics.The proposed mechanism enhances the coordination reliability across urban management service systems by integrating robust reversible watermarking into the information lifecycle.According to the reversible quantization modulation, the original reference value and information availability of the BIM under the digital watermarking technology were growing with time.The average value of the original reference value of the BIM was 0.56, and the average value of the information availability of the BIM was 0.79.The robustness of BIM under digital watermark was better than the original BIM, but the watermark capacity was lower than the original BIM.Qualitative analysis indicates that the proposed approach offers superior adaptability to geometric variations compared to conventional static watermarking schemes used in similar service environments.The method specifically addresses the reversibility requirements that standard image-based watermarking techniques fail to satisfy for high-precision engineering models.On the whole, the robustness of BIM under digital watermarking was improved by 19.71%, and the watermark capacity was reduced by 39.29%.In summary, data security protocols and digital watermarking facilitate the protection of BIM data, support resistance against geometric attacks, and enhance the robustness of the model for copyright management.
