Shanghai CA Certifies Blockchain-Based Cross-Border Signing Verification Patent Application

On January 16, 2025, the State Intellectual Property Office of China (SIPO) revealed that Shanghai Digital Certificate Certification Center Co., Ltd. (hereinafter referred to as "Shanghai CA") filed a patent application for a "Method and System for Verifiable Cross-Border Signing Based on Blockchain," with publication number CN119299071A and an application date of October 2024. This patent heralds a new era of opportunity in the cross-border electronic signature field, promising to significantly enhance the security and trustworthiness of cross-border electronic documents.

This patent primarily pertains to information security technology, specifically focusing on a blockchain-based method and system for verifiable cross-border signing. Its core function is to address the challenges of document verification in cross-border electronic signing, providing a secure, reliable, efficient, and convenient solution. The patent abstract details two crucial processes: the issuance process and the verification process.

The issuance process begins with the business system initiating a signing request. The electronic signature service node then applies for a key and CA certificate, constructs a data packet named "TDVC Issuance Structure," and sends it to the TDVC service node. The TDVC service node collaborates with the blockchain service node to record the signing request on the chain. Finally, the electronic signature service node sends a signing completion notification and the electronically signed document back to the business system, completing the issuance process.

The verification process begins with the business system sending a TDVC verification structure or the signed document to the TDVC service node. Upon receiving this information, the TDVC service node interacts with the blockchain service node and performs multiple verifications. This multi-layered verification process ensures data integrity and authenticity, effectively preventing tampering and forgery. Finally, the TDVC service node feeds back the verification results to the business system, completing the verification process.

The uniqueness of this patent lies in its ability to verify electronic documents without requiring the original electronic file to be provided to a third party. This is crucial for protecting trade secrets and maintaining data security, especially in cross-border transactions, effectively mitigating the risk of data breaches. Due to its efficiency, security, and reliability, this technology is applicable to various scenarios requiring verifiable cross-border electronic signatures.

Shanghai CA, established in 1998, is a company specializing in software and information technology services, with registered capital and paid-in capital both totaling RMB 86.58 million, headquartered in Shanghai. Over the years, the company has accumulated extensive experience and technological strength in digital certificate certification, providing a large number of digital certificates and related services to various industries. According to Tianyancha data, Shanghai CA holds multiple administrative licenses and excels in intellectual property, boasting 52 trademark registrations and 41 patent applications, demonstrating its commitment to technological innovation and intellectual property protection. Furthermore, the company has invested in five other companies and participated in 5,000 bidding projects, showcasing its substantial strength and extensive market influence.

This patent application for a blockchain-based cross-border signing verification method reflects Shanghai CA's continuous pursuit of technological innovation and excellence. The successful development and application of this technology are expected to drive the digital transformation of the cross-border electronic signature field, increasing efficiency, reducing risks, and promoting further international trade development. It not only provides businesses with more secure and reliable cross-border electronic signature solutions but also provides strong technological support for the development of the digital economy.

The application prospects of this technology are vast. In today's increasingly globalized world, the demand for secure and reliable electronic signature technologies in cross-border e-commerce, cross-border finance, and other fields is growing rapidly. This blockchain-based method and system for verifiable cross-border signing, with its unique advantages, is poised to become one of the mainstream technologies in the future of cross-border electronic signature, providing businesses with safer and more convenient guarantees for cross-border transactions.

The core value of this technology lies in its security, reliability, and efficiency. First, the application of blockchain technology ensures data immutability and transparency, effectively preventing malicious alteration or forgery. Second, the multi-layered verification mechanism further enhances the accuracy and reliability of verification, reducing the possibility of misjudgment. Finally, the ability to verify without providing the original electronic file not only protects trade secrets but also improves verification efficiency, saving time and costs.

In conclusion, Shanghai CA's patent application for a blockchain-based cross-border signing verification method represents a significant technological innovation. It effectively addresses the security and trustworthiness issues in cross-border electronic signing and provides a new direction for the future development of this field. As the technology matures and its application expands, it is expected to be widely adopted in more areas, contributing significantly to the global digital economic transformation and development. This technology holds profound significance for promoting international trade, improving cross-border cooperation efficiency, and fostering the development of the digital economy. It represents another important breakthrough for China in information security and blockchain technology, signaling China's increasingly important role in the digital economy. We can look forward to this technology finding application in even more fields and contributing to global economic development.
