With the rapid development of the economy in China and the improvement of the national living standard, as well as the stimulation of capital and individual economy, the market size of urban animals (dogs and cats) in China in 2020 reaches 2065 hundred million yuan. The expansion of the trade size places higher demands on the animal trade process, but in the current animal trade process, there are the following problems:
first, the identity and the blood system of the animal can be judged only by virtue of the animal blood system certificate provided by the seller and the experience of the consumer. Consumers often cannot judge the reliability of the origin of the blood system certificate, and no effective means is available for proving the authenticity of the blood system certificate; and experience of the self has limitations. This results in frequent fraud during the animal transaction, which can cause both economic and psychological harm to the consumer.
Secondly, the animal registration information is too simple, and usually does not comprise father and mother system information, animal inspection reports and epidemic prevention information, so that consumers cannot comprehensively know the real situation of animals, and no inquiry and verification channels exist.
Thirdly, information is not shared and circulated among animal breeding bases, animal sellers and animal hospitals, and effective assistance can not be provided for cross-regional information inquiry or animal identity authentication.
Therefore, a system and a method for identifying and tracing the identity information and the blood of an animal are needed, which solve the problems in the current animal transaction process and promote the development of animal transaction industry.
