Beijing Shiji Information Technology (002153.SZ) stated in investor relations that in terms of data security, our Shiji enterprise platform has more obvious technological advantages compared to other hotel cloud PMS products currently seen in the market. Our new generation cloud product can not store any personal data unless required by the government to be stored in plaintext. Regarding data security, it is also one of the two major design concepts of our Shiji enterprise platform from the beginning, which we call API first, Security first. We use Token key technology, and the Token key is provided by a third-party company. Another point is that our product can automatically identify the source of guest data and automatically store the data in a place that meets the local data security legal requirements.
