Background
Roll calling is often required in daily life to determine the actual number of people. Such as tour guide roll calling of tourist groups, and the statistics of the arrival situation of each student by teachers in class. The current roll call systems are:
(1) the operation method of the mobile phone with the Bluetooth function, the Bluetooth search enhancer and the roll call software installed in the computer is as follows: a. the number of the student is input into the roll call software; b. each student names a mobile phone with a Bluetooth function by using the own number; c. connecting the Bluetooth search enhancer with a computer; d. the teacher searches for the student number through the Bluetooth searching function of the computer; e. and screening out the unsearched student numbers through roll calling software.
(2) By using the wireless cellular network, each time the roll call is made, the teacher accesses the roll call server through the authentication account to generate a random number, and then publishes the random number in the classroom. Students log in the roll call server through their respective accounts and input corresponding random numbers. The server compares the input random number with the generated random number, if the input random number is consistent with the generated random number, the roll call is successful, otherwise, the roll call is unsuccessful.
The above roll call method has problems including:
1) the callee needs to configure the name of the bluetooth device or needs to collect the MAC address of the callee's bluetooth device and bind with the corresponding callee's information. The process is cumbersome and involves personal privacy information;
2) the callee can send the random code published by the callee to other callees who are not in the roll call area over the communication network, resulting in a false roll call result.

and 5: the roll call server sends the y to roll call software through a wireless cellular network;
step 6: the roll call person informs the roll call person of the random number x;
and 7: inputting a random number x' into the sign-in software by the named person;
and 8: the celebrity continuously and repeatedly sends y through a wireless broadcast channel of the near field communication system and lasts for a period of time T;
and step 9: the called person receives the broadcast sequence through the near field communication system and records the broadcast sequence as y';
step 10: the registered person registers the random numbers x 'and y' to the registration software and transmits the random numbers x 'and y' to a roll call server through a wireless cellular network;
step 11: the roll call server obtains a parameter t 'corresponding to x' through a random number x 'uploaded by the roll call person and a query table'0；
Step 12: roll call server according to x 'and t'0The sequence of the check-in is calculated,
step 13: and the roll call server compares the y 'with the y', if the y 'is the same as the y', the roll call is successfully signed by the roll call person, otherwise, the roll call is not successful.
