Abstract: Disclosed are an information synchronization method and an information synchronization device. The method includes steps of receiving an information processing request, wherein the information processing request at least include resource information and corresponding user identifier information; determines at least two clients corresponding to the user identifier information and sending the resource information to the at least two clients. The embodiment of the present disclosure acquires the correspondence between the resource information and the user identifier information, finds out the clients corresponding to the user identifier information, and pushes the resource information to the clients, realizing synchronization of the resource information among the clients corresponding to the user identifier information, so the resources on the clients are consistent in state. The method avoids the disorder caused by difference notifications received by different smart terminals, and improves user experience.
