Abstract: The present invention provides a method a device and a system for processing parallel services, which includes: determining, by a synchronization locking server, whether a service request for locking is locked after receiving a locking request sent by a service server, and locking the service request when the service request is unlocked and returning a locking success response to the service server, or returning a locking failure response to the service server when the service request is locked, so as to ensure accuracy of a processing result of the parallel services that are processed across the cities, IDCs or servers.

Abstract: The disclosure provides a login method, an open platform identification method, an open platform and an open platform system. A user terminal is guided to agree to authorize a third party application via a page of the open platform; when the connection of authorization of the user terminal succeeds, the open platform brings a first OpenID and a first OpenKey of the user to the third party application according to a login rebound protocol of the open platform; then the third party application performs user-terminal-based authorized login according to the first OpenID and the first OpenKey; and when the user terminal logging into the open platform initiates the third party application, a prompt message is sent to the user terminal with an open platform account serving as an identification of the open platform, and thus login can be implemented in various forms.
