對於企業來說，拿到你的身份證，無非就是身份證OCR（文字識別）一下，就是識別出你的身份證正反面的資訊，然後校驗以下幾種情況：
以上資訊是否都校驗是基於這款產品的目的用途。一般APP基本都是拿到姓名、身份證號校驗註冊身份的真實性即可。
除上以外，會儲存你的身份證照片，這個雖然儲存在企業伺服器上了，但是一般都是授權訪問的，如有疑問，問題排查所用。企業員工都是基於法律簽訂合同的，如果真有企業或者員工做非法的事情，那就是違犯，等待相關機關處理。
一般身份證OCR實現，都是藉助第三方介面實現，目前大部分都是採用百度實現。實現方式如下：
1.獲取百度身份證文字識別金鑰，登入https://console.bce.baidu.com/ai/?fromai=1#/ai/ocr/overview/index，拿到APP_ID、API_KEY、SECRET_KEY即可。
2.maven配置
3.controller實現

對於企業來說，拿到你的身份證，無非就是身份證OCR（文字識別）一下，就是識別出你的身份證正反面的資訊，然後校驗以下幾種情況：
註冊身份的真實性；身份證是否過期；年齡是否滿足註冊條件；性別校驗；...以上資訊是否都校驗是基於這款產品的目的用途。一般APP基本都是拿到姓名、身份證號校驗註冊身份的真實性即可。
