The invention discloses a member rights synchronizing method, device, server and system among multiple devices. The method comprises following steps: obtaining an identifier of a device as a current device identifier; obtaining the member account logging in the device; sending a synchronizing request related to the current device identifier and the member account to a server; receiving a synchronizing result returned by the server, wherein the synchronizing result is the result obtained by synchronizing the member rights and the corresponding member durations of the member account searched by the server related to to-be-synchronized device identifiers, and the member rights and the corresponding member duration of the member account related to the current device identifier, and the to-be-synchronized device identifiers are different from the current device identifier. Through the method, the device, the server and the system provided by the invention, the member rights and the corresponding durations of the same one account related to different devices are searched through the server and are synchronized; and the member rights sharing function of the same one account among multiple devices can be realized.

The invention discloses a data synchronization method and device. The data synchronization method comprises the following steps: a client acquires an access credential and a message key from a server, wherein the message key is used for encryption and decryption of follow-up interaction data between the client and the server; the client accesses the server with the access credential and requests for to-be-synchronized data at the server end from the server; after processing is finished, the client acquires the to-be-synchronized data of the client and sends the data to the server, so that the server performs data synchronization processing according to the to-be-synchronized data of the client, and a processing result sent by the server is confirmed. The performance of a mobile terminal is used reasonably, the data synchronization operation logic is delivered to the mobile terminal, namely, the client, for processing during data synchronization, so that the pressure of the server is reduced greatly, and the simultaneous processing quantity of the server is increased effectively.

Data synchronization method and device

The embodiment of the invention discloses a data synchronization method and synchronization device. The synchronization method comprises the following steps: acquiring synchronous data and a feature value thereof, wherein the feature value is obtained by computing preset key fields in the synchronous data according to a preset function; loading a corresponding relation of a locally pre-stored feature value and a data identifier, wherein the data identifier is the recognition identifier of the local data at the local; recognizing whether the data identifier corresponding to the computed feature value is existent in the corresponding relation; updating the local data corresponding to the corresponding data identifier by use of the synchronous data if the corresponding data identifier is existent. By use of the method disclosed by the embodiment of the invention, the condition that one piece of synchronous data is stored as many copies is effectively prevented, and the local resource is saved.

Data synchronization method and synchronization device

The invention provides a data synchronization method. The method comprises the following steps that: when first terminal equipment receives data, the first terminal equipment adds a timestamp when the data are received into the data; the first terminal equipment transmits the data added with the timestamp to second terminal equipment, and saves the data added with the timestamp; and the first terminal equipment receives data fed back by the second terminal equipment according to the data added with the timestamp, so that the first terminal equipment performs data synchronization according to the saved data added with the timestamp and the fed-back data. Through adoption of the data synchronization method, data synchronization of a terminal equipment cluster is realized without third-party equipment or elected data transmission equipment, and the data synchronization cost is lowered. Moreover, terminal equipment in the cluster synchronizes acquired data, so that the data synchronization reliability is ensured.

The invention discloses a data synchronization method. The data synchronization method includes the steps of receiving a login request sent by a terminal, wherein the login request comprises a login key value pair, and the login key value pair comprises a login account and a terminal device unique identification code; judging whether a storage key value pair with a login account the same as the login account of the login key value pair and a terminal device unique identification code different from the terminal device unique identification code of the login key value pair exists in a database or not; if the storage key value pair with the login account the same as the login account of the login key value pair and the terminal device unique identification code different from the terminal device unique identification code of the login key value pair exists in the database, feeding synchronous data back to the terminal. Correspondingly, the embodiment of the invention further comprises a server. By means of the data synchronization method and the server, when a user logs into different terminals, the server only feeds the synchronous data back to the terminals, the number of data transmitted between the terminals and the server is accordingly decreased, and the pressure of the server is reduced.
