Abstract

A processing method and system of cloud broadcasting and printing data, relating to the field of information security. When receiving a service obtaining request, a server processes first data in the service obtaining request into printing and broadcasting data, processes the printing and broadcasting data into first verifying data and then sends the first verifying data to a cloud broadcasting and printing service platform. The cloud broadcasting and printing service platform processes the first verifying data into second verifying data and then sends the second verifying data to a cloud broadcasting and printing all-in-one machine. The cloud broadcasting and printing all-in-one machine processes the second verifying data into printing and broadcasting data, and extracts printing information and broadcasting information from the printing and broadcasting data at a time and performs broadcasting and printing respectively.

First claim

The invention claimed is:

1. A method for processing cloud broadcasting and printing data, adapted to a system comprising a cloud broadcasting and printing all-in-one machine, a cloud broadcasting and printing service platform and a server, the method comprising the following steps:
step 101 : when receiving a service obtaining request, parsing, by the server, the service obtaining request to obtain first data and a device sequence number, generating printing and broadcasting data according to the first data, processing the printing and broadcasting data into first verifying data by using a stored enterprise key, generating a printing and broadcasting request according to an enterprise identification, the first verifying data and the device sequence number, and sending the printing and broadcasting request to the cloud broadcasting and printing service platform;
step 102 : when receiving the printing and broadcasting request, parsing, by the cloud broadcasting and printing service platform, the printing and broadcasting request to obtain the enterprise identification, the device sequence number and the first verifying data, processing, according to an enterprise key corresponding to the enterprise identification, the first verifying data to obtain the printing and broadcasting data, processing the printing and broadcasting data into second verifying data by using a device key corresponding to the device sequence number, and sending the second verifying data to the cloud broadcasting and printing all-in-one machine corresponding to the device sequence number; and
step 103 : when receiving the second verifying data sent by the cloud broadcasting and printing service platform, processing, by the cloud broadcasting and printing all-in-one machine, the second verifying data by using a stored device key to obtain the printing and broadcasting data, extracting printing information and broadcasting information from the printing and broadcasting data respectively, printing the printing information and broadcasting the broadcasting information, and returning a result of completing printing and broadcasting to the cloud broadcasting and printing service platform.

2. The method according to claim 1 , wherein the processing of the printing and broadcasting data into the first verifying data by using the stored enterprise key comprises: using, by the server, the enterprise key to sign the printing and broadcasting data to obtain signing data, generating first verifying data according to the printing and broadcasting data and the signing data; and
the processing, according to the enterprise key corresponding to the enterprise identification, of the first verifying data to obtain the printing and broadcasting data comprises: authenticating, by the cloud broadcasting and printing service platform, signing data in the first verifying data according to the enterprise key, and obtaining the printing and broadcasting data in the first verifying data when authenticating is successful.

3. The method according to claim 1 , wherein the processing the printing and broadcasting data into the first verifying data by using the stored enterprise key comprises: encrypting, by the server, the printing and broadcasting data according to the enterprise key to obtain the first verifying data; and
the processing, according to the enterprise key corresponding to the enterprise identification, of the first verifying data to obtain the printing and broadcasting data comprises: decrypting, by the cloud broadcasting and printing service platform, the first verifying data according to the enterprise key to obtain the printing and broadcasting data.

4. The method according to claim 1 , wherein before sending the second verifying data to the cloud broadcasting and printing all-in-one machine corresponding to the device sequence number, the method further comprises:
step W 1 : determining, by the cloud broadcasting and printing service platform, whether a result of completing broadcasting and printing corresponding to a last piece of the second verifying data returned by the cloud broadcasting and printing all-in-one machine corresponding to the device sequence number is received, if yes, sending the second verifying data to the cloud broadcasting and printing all-in-one machine corresponding to the device sequence number, otherwise, executing step W 2 ;
step W 2 : determining, by the cloud broadcasting and printing service platform, whether time for sending the last piece of the second verifying data exceeds a first preset time period, if yes, sending the second verifying data to the cloud broadcasting and printing all-in-one machine corresponding to the device sequence number; otherwise, sending the second verifying data to the cloud broadcasting and printing all-in-one machine corresponding to the device sequence number after exceeding the first preset time period; and
recording the second verifying data sent by the cloud broadcasting and printing service platform to the cloud broadcasting and printing all-in-one machine corresponding to the device sequence number last time as the last piece of the second verifying data.

5. The method according to claim 4 , wherein when sending the last piece of the second verifying data, activating the cloud broadcasting and printing service platform, a timer and a counter; and
the sending of the second verifying data to the cloud broadcasting and printing all-in-one machine corresponding to the device sequence number after exceeding the first preset time period is replaced with:
step N 1 : when time of the timer reaches second preset time, determining, by the cloud broadcasting and printing service platform, whether a result of completing printing and broadcasting for sending the last piece of the second verifying data is returned, if yes, sending the second verifying data to the cloud broadcasting and printing all-in-one machine corresponding to the device sequence number; otherwise, executing step N 2 ;
step N 2 : determining, by the cloud broadcasting and printing service platform, whether counting number of the counter reaches a preset number of times, if yes, sending the second verifying data to the cloud broadcasting and printing all-in-one machine corresponding to the device sequence number; otherwise, executing step N 3 ; and
step N 3 : resetting, by the cloud broadcasting and printing service platform, the timer to zero and restarting the timer, updating the counter, sending the last piece of the second verifying data, and going back to step N 1 .

6. The method according to claim 1 , wherein the generating of the printing and the broadcasting data according to the first data comprises: extracting, by the server, valid information from the first data, and processing the valid information into a printing and broadcasting message according to a printing and broadcasting message format; and
the extracting of the printing information and the broadcasting information from the printing and broadcasting data respectively comprises: extracting, by the cloud broadcasting and printing all-in-one machine, the printing information and the broadcasting information from the printing and broadcasting message respectively.

7. The method according to claim 1 , wherein the generating of the printing and the broadcasting data according to the first data comprises: extracting, by the server, valid information from the first data and taking the valid information as the printing and broadcasting data; and
the extracting of the printing information and the broadcasting information from the printing and broadcasting data respectively is: processing, by the cloud broadcasting and printing all-in-one machine, the valid information into a printing and broadcasting message according to a printing and
