Description

Technical Field

[0001] The present invention relates to the technical field of traditional certificate anti-counterfeiting, and specifically to a method and system for anti-counterfeiting traditional certificates based on mobile phone NFC verification. Background Art

[0002] Since the implementation of the real estate registration system, real estate registration has always received extensive attention from the public, and all work has tended to be improved with the joint efforts. Among them, the anti-counterfeiting work for real estate certificates is an indispensable part. The current anti-counterfeiting technology for real estate certificates still uses traditional methods such as covers, papers, anti-counterfeiting watermarks, and stamps for anti-counterfeiting verification, and also uses ultraviolet lamps for anti-counterfeiting verification. However, all these verification and identification methods require manual participation, and whether a real estate certificate is forged needs to be judged manually, which is time-consuming and laborious.

[0003] As the amount of data continues to increase, the challenges of this centralized data processing system have become increasingly prominent. Massive data requires a large amount of storage space; the high concentration of data will inevitably cause problems such as "network latency" and "denial of service attacks", and this system also needs to establish and maintain a trusted data environment to ensure the authenticity of the certificates, and the cost of establishing and maintaining a trusted environment is extremely expensive; at the same time, it also faces the problem of being difficult to upgrade. This centralized processing form is no longer applicable to the current network environment. Transplanting the graduation certificate system to the cloud computing environment and using the massive storage space and rich computing resources of cloud computing to solve the verification problem of existing graduation certificates. Its main technical means is to solve the data authentication problem in the cloud environment.

[0004] Certificates are used more and more frequently in people's lives, and people also have more and more certificates. Since a large amount of information is carried on the certificates, higher requirements are placed on the security, authenticity, and non-replicability of the certificates. Currently, certificate anti-counterfeiting technologies are mainly divided into two categories: one is visual anti-counterfeiting technology, and the other is machine-readable anti-counterfeiting technology. The anti-counterfeiting of the typical second-generation resident ID card combines technologies such as digital anti-counterfeiting technology, radio frequency anti-counterfeiting technology, and printing anti-counterfeiting technology, which greatly improves the security factor of the resident ID card. However, not all certificates can be as carefully designed as the second-generation resident ID card and use multiple anti-counterfeiting technologies to ensure their security.

[0005] Even so, mobile phone NFC can only detect the RFID chip in the second-generation ID card, but cannot read the anti-counterfeiting information in the chip. There are also similar problems with the self-adhesive chips affixed to the business licenses issued by the market supervision department. Mobile phone NFC can only detect the chip or read a section of the code. As non-professional mobile phone holders of the public, they cannot truly check the authenticity. The same is true for the business licenses issued by the tobacco management department.

[0006] High-end baijiu brands such as Moutai and Wuliangye have also developed their own exclusive mobile NFC anti-counterfeiting query and verification systems. Such systems are just exclusive APPs developed by product manufacturers for product anti-counterfeiting. When consumers check, they need to download and use this exclusive APP, which is troublesome and cumbersome to operate. Moreover, it cannot determine the authenticity once and for all. Famous wine collection is very common, and many genuine products before the application of this APP cannot be judged by this APP. Such exclusive APPs cannot be extended to the anti-counterfeiting of traditional certificates.

[0007] Current anti-counterfeiting technologies for traditional certificates mainly use traditional methods such as covers, papers, anti-counterfeiting patterns, and seals for anti-counterfeiting verification. There is also anti-counterfeiting verification through ultraviolet lamps. However, all these verification and identification methods require manual participation. Whether a traditional certificate is forged needs to be judged manually, which is time-consuming and laborious, and it is difficult to distinguish between genuine and fake. Summary of the Invention
