Wang first shot to prominence in the second season of The Brain, a TV program which shows people with exceptional brainpower, in 2015. He once correctly picked out a specific cup of water from 520 cups and identified four lip prints from 700 lipstick prints.

"Mark" is the brainchild of Zhejiang Ant Small & Micro Financial Services Group, e-commerce giant Alibaba's financial affiliate. It can be used in verification of ID in online finance and it can identify images one-on-one in ID verification, account logging, or password recovery, which is unlike the search for one facial image from a reservoir of photos, according to its developer team.
