Many consumers prefer luxury goods, and in particular the MZ (Millennial, Z) generation has a high preference for luxury goods and perceives luxury goods as ordinary consumption that is not special, and sees luxury goods as a means to make a profit through reselling. In general, products and receipts sold in department stores are considered 100% genuine, but there are cases of second-hand sellers selling counterfeit goods with department store receipts attached, which is increasing consumer damage. When purchasing a product from a secondhand site, even if the seller has a department store receipt or a certificate of authenticity, the buyer must ensure that seller's products/artwork are counterfeit or not, in order to avoid monetary harm.

Art works are similar to luxury goods, the number of cases where consumers are harmed by the sale of elaborately forged counterfeit products with a certificate of authenticity received using the genuine product is increasing. In this way, when the receipt or appraisal is genuine, there is virtually no way for the general public to directly check whether the product(artworks) is a counterfeit, so the damage to producers and consumers is getting more and more serious, so countermeasures are urgently needed.
