Chinese AI company Megvii, patented technology of detecting dog nose print

 


Companion animal (pet) registration system,

Since 2014, Korea has been implementing the companion animal registration system for the purpose of protecting animals, preventing loss and abandonment. It is compulsory to register within 30 days from the date the companion animal you are raising turns 2 months. When registered, the wireless identification device (microchip) is implanted into the animal's body. If you don’t want this, companion animals can be recognized by attaching an external wireless identification device or a registration identification tag.

Low registration rate, why?

The number of domestic dogs is estimated to be about 6.62 million. According to data from the Ministry of Agriculture, Food and Rural Affairs in 2019, only about 2.09 million dogs were registered, showing a low registration rate of about 30%. Officials regard insufficient publicity about the system, crackdowns that are not actually implemented, and questions about the effectiveness of registration as reasons for the low registration rate. In particular, the main reason is that registration can be done by means of an external wireless identification device, identification tag, etc. other than the built-in microchip for reasons of effectiveness. If the external devices are not attached to the companion animal, there is no way to check the animal registration information, and even if it is lost, it is difficult to verify the owner's information, so there is a high possibility of loss or abandonment. However, most owners who choose an external identification device have doubts about safety, such as inflammation caused by the embedded microchip inside the body. Although each has its own strengths and weaknesses, in fact there has been no way to compensate for both.

Detection method using dog print,

Not long ago, Megvii, an artificial intelligence startup company in China, patented a biometrics technology that can identify dog ​​nose print and find a lost dog. Megvii, which possesses facial recognition technology that can find a specific person out of a large number of people in a few seconds, said that dogs can be recognized by faces with artificial intelligence like humans, and also be identified by print on their noses like human fingerprint. Dog nose print do not change shape with age, so it is known that in the past, in Canada, companion animals were registered as a method of copying dog nose print.

Megvii's patent of dog nose print detection,

Megvii’s patent is titled ‘Dog nose print feature point detection method, device, system and storage medium’'. According to the patent, the dog's nose feature points are registered as coordinates, and the animal can be identified through the distance deviation of the coordinates. Megvii said that the detection rate using this technology was 95% accurate. The app developed with the company's dog detection-related technologies, including this patent, revealed that the identification accuracy is 99%. Megvii, a facial recognition technology company, is known to continue research on how to identify dogs, and patents are also pending.

How to distinguish nose print, can it be applied to Korea?,

The detection method using nose print is thought to be a very suitable method for pet owners who were reluctant to insert microchips into the body. It will also be very useful for those who have been bothered to invest time in registration. This is because you can simply register with the app through photos of dogs taken from various angles. Through this method, I wonder if it is possible to expect a higher registration rate than now. We look forward to the introduction of this technology in Korea as soon as possible to solve the problem of low registration rates.
