I. Project Background and Strategic Significance
Xiamen Information Group Big Data Operation Co., Ltd. (hereinafter referred to as “Xiamen Big Data”), as a state-owned enterprise under the Xiamen Municipal Government, is responsible for integrating and operating government and industrial data across the city. In 2024, Xiamen launched the "Smart City 3.0" upgrade plan, which required integrating real-time data interfaces from sectors such as finance, transportation, and healthcare. However, challenges such as low technical integration efficiency and insufficient data security compliance emerged.
Shanghai Huibi Information Technology Co., Ltd. (hereinafter referred to as “Huibi Information”), a leading domestic provider of data interface technical services, possesses significant advantages in its independently developed API gateway management platform and dynamic encryption technology. In May 2024, the two parties signed the "Data Interface Technical Services Agreement," and due to the remarkable results achieved, four supplementary agreements were successively signed, ultimately extending the cooperation term to 2028.
II. Core Cooperation Content and Technological Innovation
- Data Interface Integration Solution
- Pain Points: Xiamen Big Data’s legacy system suffered from issues such as inconsistent interface standards, high response latency (averaging 800ms), and a cross-domain call failure rate exceeding 15%.
- Solutions:
- Huibi Information deployed a distributed API middleware platform to standardize 12 types of core interfaces (e.g., government affairs, finance, transportation), reducing response time to under 200ms.
- Implemented a dual authentication mechanism combining OAuth2.0 and SM4 encryption to ensure graded controllability of data access permissions.
- Provided a real-time monitoring dashboard with an automatic circuit breaker mechanism for abnormal calls, shortening fault recovery time from 2 hours to 10 minutes.
- Key Performance Metrics
- Core Reasons for Extended Cooperation
- Technical Continuity: The "data sandbox" testing environment custom-developed by Huibi Information for Xiamen Big Data supported compliant data development needs for 40 enterprises and institutions in the city.
- Policy Compliance Assurance: Following the 2025 revision of the "Data Security Law," Huibi Information rapidly iterated interface protocols, achieving both ISO 27001 and Ministry of Public Security Level 3 cybersecurity certifications.
- Cost Optimization: Through a tiered pricing model for interface calls, Xiamen Big Data reduced annual technical procurement costs by 32%.
III. Typical Application Scenarios and Value Delivery
- Scenario 1: Smart Traffic Real-Time Scheduling
Huibi Information provided traffic signal API and bus GPS data interfaces, achieving:- A 28% reduction in peak-hour congestion indices on main roads in Xiamen Island;
- 95% accuracy in bus arrival time predictions (previously 70%).
- Scenario 2: Cross-Border Financial Data Verification
Through Huibi Information’s blockchain cross-domain interfaces, Xiamen Big Data enabled banks to:- Conduct "one-click verification" of enterprise business, tax, and customs data, reducing single transaction review time from 1 day to 5 minutes;
- Support Xiamen Branch of China Construction Bank in intercepting 23 fraudulent trade financing cases involving RMB 120 million.
- Scenario 3: Pandemic Emergency Response
During a COVID-19 outbreak in Xiamen in 2025, Huibi Information urgently enabled nucleic acid testing data interfaces, achieving:- Real-time data synchronization across health, police, and community departments, improving epidemiological efficiency by 60%;
- A staggered testing scheduling system that reduced crowd gathering risks, earning recognition from the State Council’s Joint Prevention and Control Mechanism (Joint Prevention and Control Mechanism).
IV. Innovative Cooperation Model and Industry Benchmark Significance
- Dynamic Supplementary Agreement Mechanism
The two parties established an "annual technical assessment + flexible supplementary agreements" model, adjusted every six months based on business needs:- July 2024 Supplementary Agreement: Added financial data desensitization services;
- February 2025 Supplementary Agreement: Expanded the Fujian-Taiwan cross-border data transmission dedicated line.
- Industry Impact
- The project was selected as a "Typical Case of Market-Oriented Allocation of Data Elements 2025" by the Ministry of Industry and Information Technology;
- The cooperation model has been replicated and promoted in 6 cities, including Fuzhou and Hangzhou.
