An association logic that associates a non-text message type with specified information is established. The association logic includes at least identification of the non-text message type, allowing a message type in line with the association logic to be identified by the identification. A first message is monitored. A first identification corresponding to the first message is obtained by analysing the first message. It is detected, according to the first identification, whether the first message is of the message type in line with the association logic. It is determined that the first message supports display of the specified information when it is detected that the first message is of the message type in line with the association logic.
