1. wechat's fingerprint payment is said to need to upload the fingerprint information to the database and then compare it. If they are consistent, they will be correctly identified for payment. However, Huawei Xiaomi and other manufacturers think that this way of uploading to the cloud is unsafe and easy to be stolen, so they don't agree with this way.
2. As an ordinary mobile phone manufacturer like Huawei Apple, every mobile phone has a unique key in its chip when it leaves the factory. This key is written once when the chip leaves the factory and cannot be read and modified from the outside. The fingerprint data of Huawei mobile phone can only be written and deleted, and will not be uploaded to any server, nor will it be read by any third-party program. Therefore, due to the conflicts between Tencent and Huawei in the past, Huawei's mobile phone still does not support WeChat fingerprint payment.
3. Huawei is a security solution based on chip hardware. The programs of fingerprint encryption, storage and verification run in the physically isolated secure OS in the HiSilicon chip, and the programs in the Android environment cannot be directly accessed. Even after the phone is root, this part cannot be accessed and tampered with.
4. 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 by AES256 algorithm in the local mobile phone, and each chip has a unique key, which 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.
5. The fingerprint security program provides signature verification results to the outside world, and the whole process is protected by RSA 2048 signature, so it cannot be forged or tampered with. On 20 16 1 month, wechat announced Tencent SOTER: Tencent biometric authentication open platform, which will help developers realize biometric authentication function quickly. SOTER is a set of standards for biometric authentication, which defines the functions of each link, the indicators to be achieved and the implementation methods when users use equipment for biometric authentication.
To put it simply, as a partner of Wechat Soter, users of mobile phone brands can use the WeChat payment function with the help of biometric technologies such as fingerprint identification, otherwise they can only use traditional password payment.
6. Supporting Tencent's WeChat SOTER platform is to upload the user's biometric information to Tencent's server and compare it in the cloud instead of comparing it in the local mobile phone system. This is extremely risky, which means handing over the private information of many users to third parties, so for users, not only Huawei, but also Xiaomi does not support WeChat fingerprint payment.
