And carrying out Hash operation on the face information to obtain a character string with a fixed length. The server is pre-stored or provided with a database, the database is related to the activity identification, and different activities are related to different databases. The index of the data stored in the database is a hash address, and is searched in an address space indicated by a hash value obtained by processing the face information based on a hash operation.
The database associated with the target activity stores facial information and identification of students who have participated in the target activity within a preset time length, and the preset time length can be determined according to actual needs.
S308, judging whether the identification associated with the face information is inquired.
If the query result is yes, executing S310; if the query result is negative, S309 is executed.
S309, the face information is associated with the identity of the target user and then written into the database.
The server determines that the target user is a student who participates in the target activity for the first time, calculates the face information based on the same hash algorithm used in S307 to obtain a hash value, and writes the identity into the address space indicated by the hash value.
S310, judging whether the user identification of the target user is the same as the inquired identity identification.
If the corresponding data is queried in the database, the server compares whether the user identifiers obtained in step S305 are the same as the user identifiers queried in the database, and if so, performs step S311; if not, go to step S312. The reason why the identification stored in the database in which the face information is an index is not identical to the identification acquired in S305 includes: the target user registers a plurality of different login information for a plurality of times so as to realize the trial listening of free courses provided by the online education platform for a plurality of times.
S311, generating first prompt information, displaying the first prompt information on the first terminal device, and stopping pushing the second video stream from the second terminal device to the first terminal device.
