c# - 唯一设备 ID UWP

Question

几天以来，我一直在尝试从我的 Windows Phone 设备上获取 MAC 地址，但都没有成功。我正在尝试为我的手机、平板电脑等获取唯一 ID。我找到了 HardwareToken 类和下面的代码

HardwareToken token = HardwareIdentification.GetPackageSpecificToken(null);
                IBuffer hardwareId = token.Id;
                HashAlgorithmProvider hasher = HashAlgorithmProvider.OpenAlgorithm("MD5");
                IBuffer hashed = hasher.HashData(hardwareId);
                string hashedString = CryptographicBuffer.EncodeToHexString(hashed);

使用此代码我正在接收 ASHWID。这真的很独特吗？

Answer 1

Using this code I am receiving ASHWID. Is that really unique?

这取决于。在手机/平板电脑上比在台式机上更有可能。您可以找到确切的答案 at MSDN :

The ASHWID provides a strong binding between the app/package and the device by representing several individual hardware characteristics. In order to protect user privacy, the ASHWID varies from app to app. Unless the underlying hardware has changed, two calls from the same app will result in identical ASHWIDs. However, the ASHWID changes if the hardware profile of the device changes, such as when the user unplugs a USB Bluetooth adapter. The back-end cloud service can verify the ASHWID and compare it with previously reported values.
