The application relates to a data interaction method of a check-in system, a check-in system and a computer device. When a user password fed back by a server is acquired, a password synchronization header can be determined by determining original data of privacy and first local information associated with a user end; the original data is encrypted by the user password and the first local information to obtain encrypted data; when the encrypted data and the password synchronization header are data-encapsulated, encapsulated data sent to the server is obtained. Since the password synchronization header is a generation element of an encryption key, and each original data corresponds to an encryption key, when privacy protection of a large amount of user data is involved, the encrypted data and the password synchronization header are directly data-encapsulated, a password fed back by the server does not need to be acquired, and the password can be dynamically generated without being set by the user, so that the security strength of interaction between user data is improved.

The preset information can maximally reduce the cost of executing an identity authentication protocol after the UAV takes off. The security strength is simultaneously enhanced by negotiation and preset information, the flexibility of the protocol is increased, and the calculation efficiency is improved.
