Reduce fraudulent use of your services by managing device state and asserting app integrity.
The DeviceCheck services consist of both a framework interface that you access from your app and an Apple server interface that you access from your own server.
Using the DCDevice class in your app, you can get a token that you use on your server to set and query two binary digits of data per device, while maintaining user privacy. For example, you might use this data to identify devices that have already taken advantage of a promotional offer that you provide, or to flag a device that you’ve determined to be fraudulent. The server-to-server APIs also let you verify that the token you receive comes from your app on an Apple device.
Someone who modifies your app and distributes it outside the App Store can add unauthorized features like game cheats, ad removal, or access to premium content. The App Attest service gives your app a way to assert its validity so that your server can more confidently provide access to sensitive resources. You use the DCAppAttestService class to generate a special cryptographic key on the device, and have Apple attest to the validity of that key. You then use that key to assert the validity of your app whenever you request sensitive data from your server.
通过管理设备状态和断言应用程序的完整性，减少您服务的欺诈使用。
DeviceCheck 服务包括您从应用程序访问的框架接口和您从自己的服务器访问的苹果服务器接口。
在您的应用程序中使用 DCDevice 类，您可以获取一个令牌，您可以在您的服务器上使用该令牌设置和查询每个设备的两个二进制数据位，同时保护用户隐私。例如，您可以使用这些数据来识别已经利用您提供的促销优惠的设备，或者标记您确定为欺诈的设备。服务器到服务器的 API 还允许您验证您收到的令牌来自于苹果设备上的您的应用程序。
修改您的应用程序并在 App Store 之外分发它的人可以添加未经授权的功能，如游戏作弊、广告移除或访问高级内容。App Attest 服务为您的应用程序提供了一种断言其有效性的方法，以便您的服务器可以更有信心地提供对敏感资源的访问。您可以使用 DCAppAttestService 类在设备上生成一个特殊的加密密钥，并让苹果证明该密钥的有效性。然后，您可以使用该密钥在从服务器请求敏感数据时断言您的应用程序的有效性。
