Digital DNA, now called "trusted ID", was developed by Beijing Digital Alliance network technology. Digital DNA can effectively identify technical fraud means such as virtual machine, real machine changing code, all kinds of mobile phone reuse, and sending data requests directly to the server in APP promotion. Real-time query of trusted device database based on digital alliance authentication will provide accurate delivery basis for channels, advertisers and advertisers.
"Digital DNA" module can identify 96% of existing users and feed back new users accurately and effectively. The recognition error of abnormal equipment is less than 1.04%, which is the highest in the industry.
If you want to do APP promotion, O2O will send coupons, and if you are afraid of being brushed away by fraud, you will use digital DNA.
It's not too much to ask for adoption in such detail.
