Design And Application Of RSA Algorithm And QR Code Of Anti-counterfeiting Technology Used In Fresh Products Filed

With the constantly booming development of market economy, the development of the current economic system is more and more perfect. However, sham and shoddy commodities are inundated in the China’s socialist market economy. Although various kinds of existing anti-counterfeiting technology have been widely used, there is still a variety of issues affecting the anti-counterfeiting effect in the real situation, especially influencing products that are closely related with our daily life, such as fresh vegetables, fresh fish, meat products, dairy products and so on. Although Chinese government has been trying to reinforce the management, it does not turn out as imagined. It is mainly because that through imitation and copy, manufacturers can attain a huge interest, therefore criminals go on track and attempt to improve the level technology, using illegal high-tech means to imitate and copy fresh vegetables, fresh fish and meat products, dairy products, and other important commodities.To solve the problems mentioned above, firstly, an effective encryption security technology is needed, to ensure that it can not easily be counterfeited, and in this way excellent brands can be created to enhance brand level. Secondly, we should consider how to make the product security verification operation simple and efficient. Smart phones have been very popular in modern life, and QR code has been widely Applied in electricity business, food, and websites. Considering the frequent contact and the popularity of the widespread technology, now the equipment with a QR code information as a product container to store the product quality information to the inside can effectively improve the security capabilities; at the same time, using RSA algorithm as a powerful tool to encrypt the information, as its encryption keys require different characteristics, so it can improve the technical difficulty of crack. In this way, QR code, smart phones and asymmetric encryption can be seamlessly combined to generate a QR code after the encryption of products information, which is the unique identity of products, helping consumers to quickly identify the authenticity through mobile phones.The system mainly involves the following technologies: QR code technology, RSA algorithm, as well as QR code image processing technology and so on. Its main innovation is that combining QR code and RSA to solve the anti-counterfeiting questions of fresh products.It has many advantages. Consumers can conveniently use mobile App with public key encryption to scan QR code of the product to fast identify the authenticity.The system can realize real-time and local identification of the authenticity, which meets the public’s demand to identify products in a fast and precise way.The system uses the QR code as the carrier for enciphered information of asymmetric encryption system. QR code is printed on the surface of the goods, which has a low cost, the capability of a big data storage volume encryption, the capability of resisting disturbance, the capability of error correcting. Meanwhile, QR code has many characteristics of being simple, fast and effective.The system has a low requirement of the phones’ function, and general smart phones based on Android system can be used as authentication terminal equipment.The system and product system of companies make a butt joint, saving various quality information as anti-counterfeiting information in QR code, which is not only the anti-fake identity of products, but also a quality tag of products.
