#### Data desensitization

In the process of displaying information such as name, ID number, bank card number, mobile phone number, etc., in order to avoid the leakage of personal privacy, a form of hidden anti-display is adopted.

  <div class="doc-cutline do">
    <div class="doc-cutline-item">
      <img src="https://pt-starimg.didistatic.com/static/starimg/img/Y3ywMpuHs41545904053656.jpg" style="max-height:410px;">
