This invention discloses a method, system, apparatus, and online payment clearing platform for processing reconciliation files. The method includes: generating a key file corresponding to a terminal; generating a first reconciliation file based on the transaction flow data of the terminal within a transaction period; encrypting the first reconciliation file based on a first digital envelope included in the key file to generate a second reconciliation file; performing hash signature processing on the key file to generate a first signature file; and performing hash signature processing on the second reconciliation file to generate a second signature file; and sending the key file, the first signature file, the second reconciliation file, and the second signature file to the terminal, so that the terminal can perform business reconciliation processing based on the received files. Encrypting the reconciliation file through a two-layer data encryption mechanism improves the security of the information data in the reconciliation file; the two-layer data signature mechanism enhances the non-repudiation and tamper-proof capabilities of the reconciliation file.

The application provides a general cooperative channel image file processing method, system and device. The system comprises: a business access interface, configured to receive a file processing request initiated by at least one business invoker, and call back a system processing result to the corresponding business invoker; a unified gateway module, configured to authenticate, limit flow and route distribute the received file processing request; a core service module, configured to receive the file processing request routed and distributed by the unified gateway module, acquire an image file from a cooperative channel party system according to the file processing request, and perform file processing on the image file; an adaptation module, configured to provide the core service module with a unified service call and file processing interface for communication with different cooperative channel party systems; and a storage module, connected with the core service module and the adaptation module, configured to centrally store image files, signature files and structured data required for system operation.

An example operation includes one or more of receiving at a server at least one of a component calibration file and a component configuration file from a vehicle, receiving at the server a file signature of the at least one of the component calibration file and the component configuration file from the vehicle, parsing via the server the at least one of the component calibration file and the component configuration file based on the file signature and verifying via the server the at least one of the component calibration file and the component configuration file based on the file signature.

An online signature system, method, and an electronic apparatus are provided. Through a remote conference server, an electronic apparatus and another electronic apparatus perform a remote communication procedure. In a process of performing the remote communication procedure, a signature task is transmitted to the electronic apparatus through the remote conference server. The electronic apparatus is connected to an electronic signature server based on the signature task, and displays an assignment file transmitted by the electronic signature server on a display. In response to receiving a signature object associated with the assignment file, the signature object is transmitted to the electronic signature server, so that the electronic signature server combines the signature object with the assignment file to obtain a signed file.
