Does Gome U7 support WeChat fingerprint payment?
Gome U7 currently does not support WeChat fingerprint payment. If you want to pay by fingerprint, you can pay by Alipay fingerprint first. In other words, Huawei nova2s does not support WeChat fingerprint payment, and only supports Alipay fingerprint payment.
Why does Gome U7 not support WeChat fingerprint payment?
1. The programs for fingerprint encryption, storage and verification run in the physically isolated secure OS in HiSilicon chip, and cannot directly access the programs in the Android environment. Even after the phone is root, this part cannot be accessed and tampered with.
2. The mobile phone does not save the fingerprint image, only saves the extracted template information, and cannot restore the fingerprint image through the fingerprint template. All fingerprint template information is only encrypted locally by AES256 algorithm, and each chip has a unique key. This key is written in a lump sum when the chip leaves the factory and cannot be read and modified from the outside. Fingerprint template data can only be written and deleted, but not read and modified, so it will not be uploaded to any server or read by any third-party program.
3. The fingerprint security program provides signature verification results to the outside world, and the whole process is protected by RSA2048 signature, so it cannot be forged or tampered with.
