Claim:
A service accessing control method, comprising: initiating, by a first client, a game invitation to at least one additional client, and generating a service group for executing an online game comprising the first client and the at least one additional client; wherein the first client and the at least one additional client are messenger clients, and respectively include a service function plug-in; wherein initiating, by the first client, the game invitation to the at least one additional client to generate the service group comprises: obtaining, by the service function plug-in of the first client, a game list from a server and generating the game invitation for executing the online game; wherein the number of clients allowed to access a game table is greater than or equal to the number of the clients in the service group; responding, by the at least one additional client, to the game invitation and participating in the service group; generating, by any of the clients in the service group, a key for the service group; searching, by any of the clients in the service group, for the game table on the server; accessing and encrypting, by the client that first searches out the game table, the game table with the generated key, and notifying the other clients in the service group; writing the key into an accessing right parameter of the game table; accessing, by the other clients in the service group, the encrypted game table with the generated key after receiving the notification from the client that first searches out the game table; saving, by the server, Unique Identities (UIDs) of all the clients in the service group; decrypting, by the server, the game table after determining that UIDs of clients that currently access the game table match the UIDs of a client in the service group; allowing, by the server, the accessing client to access the game table when the key sent from the selected client is identical with the key in the accessing right parameter; and deleting, by the server, the key in the accessing right parameter of the game table after decrypting the game table.
