With the rapid development of Chinese economy, the improvement of national living standard and the stimulation of capital and single economy, the consumption market scale of Chinese town animals (cats and dogs) reaches 2065 hundred million yuan in 2020. The enlargement of the trading scale puts higher demands on the animal trading process, but in the current animal trading process, the following problems exist:
first, the identity and ancestry of an animal can only be determined by the animal ancestry certificate provided by the seller and the experience of the consumer. Consumers often cannot judge the reliability of the source of the certificate of descent and have no effective means for proving the authenticity of the certificate of descent; and the self experience has limitations. This results in fraud often occurring during animal transactions, causing both economic and psychological harm to the consumer.
Secondly, the animal registration information is too simple, and usually does not include father and mother information, animal inspection reports and epidemic prevention information, so that consumers cannot comprehensively know the real condition of animals, and no inquiry and verification channel exists.
Thirdly, information among the animal breeding base, the animal selling seller and the animal hospital is not shared and circulated, and effective help cannot be provided for cross-regional information inquiry or animal identity authentication.
Therefore, a credible system and method for tracing animal identity information and ancestry identification are needed to solve the problems in the current animal trading process and promote the development of the animal trading industry.
