HarmonyOS 口令输入界面可以被截屏或者录屏，如何防止

防止截屏示例demo如下： 在module.json5中添加权限

"requestPermissions": [
{
  "name": "ohos.permission.PRIVACY_WINDOW"
}
]

//XXX.ets

import { window } from '@kit.ArkUI';

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';
  @State isPrivacyMode: boolean = true;
  async aboutToAppear() {
    let ww = await window.getLastWindow(getContext(this))
    await ww.setWindowPrivacyMode(true);
  }
  build() {
    RelativeContainer() {
      Text(this.message)
    }
    .height('100%')
    .width('100%')
  }
}
