On the basis of the above embodiments, further improvements are made, and in the present invention, the print request of the mobile terminal includes the identity information of the mobile terminal and the file identification information of the file to be printed. In the technical scheme, in order to improve the efficiency of searching the file by the memory and check the authority and identity of the mobile terminal by the memory, the mobile terminal sends the identification information of the corresponding file to the printing equipment as part of the printing request, the printing equipment forwards the identification information to the cloud end, and the cloud end identifies and confirms the identification information of the file, so that the file to be printed can be conveniently and quickly called from the memory.
Referring to fig. 2, based on the above embodiments, the present invention is further improved, in which the process of the cloud verifying the mobile terminal includes:
the cloud generates a biological characteristic verification request according to the printing request, and sends the biological characteristic verification request to the mobile terminal corresponding to the identity information; after receiving the biological characteristic verification request, the mobile terminal feeds back biological characteristic verification information to the cloud; and the cloud end verifies whether the holder of the mobile terminal at the moment is a legal holder or not according to the biological characteristic verification information of the mobile terminal. In the embodiment, the mobile terminal is determined to be not stolen through biological characteristic identification, and the printed file is ensured to be printed for the corresponding person.
On the basis of the above embodiments, the present invention is further improved, in the present invention, the file identification information of the file to be printed is fed back to the cloud, the cloud checks the file identification information fed back by the mobile terminal with the file identification information in the print request, and after checking, the file identification information is identified as the final identification information of the file to be printed. In this embodiment, in order to further verify whether the printing verification information matches with the file to be printed, the printer needs to further provide the verification information of the file to be printed, that is, the file identification information of the file to be printed is sent to the cloud end through the mobile terminal alone, and the cloud end verifies whether the identification information of the file to be printed sent from the mobile terminal is consistent with the file identification information of the file to be printed sent from the printing device, so that the file identification of the mobile terminal is prevented from being forged after the printing device is invaded, and the high-permission file is extracted. And after the file identification information fed back by the mobile terminal is checked to be correct with the file identification information in the printing request at the cloud end, the file identification information is identified as the final identification information of the file to be printed, and the final identification information is sent to the storage.
With reference to fig. 2, based on the above embodiments, the present invention is further improved, in which a process of sending a file to be printed to a printing device by a cloud control storage includes: the cloud matches a corresponding memory for the mobile terminal according to the identity information of the mobile terminal; the cloud sends the information of the printing equipment, the identity information of the mobile terminal, the final identification information and the biological characteristic verification information to the memory; the memory calls a file set corresponding to the printing authority of the mobile terminal according to the identity information of the mobile terminal, calls a corresponding file to be printed in the file set according to the final identification information and sends the file to be printed to the printing equipment.
Referring to fig. 2, the present invention is exemplified by the interconnection verification of a mobile phone and a printing device, and the mobile terminal of the present invention may be a mobile phone installed with a corresponding application program, and may also be a pad, a notebook computer, or other electronic devices with data processing and information transmission functions. The user can check the file list with the printing authority in the mobile phone application and print the file. When a user needs to print, a file to be printed is selected from a file list in the mobile phone application, and the mobile phone application generates a printing request according to the selection of the user and the corresponding file identification information to be printed and the identity information of the mobile phone application binding person and sends the printing request to the printing equipment. The printing equipment or the gateway of the printing equipment is the printing equipment which is networked and can adopt any one or more near field communication modes of wifi, a code scanner, infrared, Bluetooth or a radio frequency module. In this embodiment, the mobile terminal may send the print request to the printing device in a short-distance communication manner, such as two-dimensional code or radio frequency code scanning. In this embodiment, a two-dimensional code is taken as an example, a print request is generated into two-dimensional code information in a mobile phone application program, a print request of a mobile terminal is acquired by a printing device or a gateway of the printing device in a code scanning manner, then the print request is sent to a cloud, and after the cloud receives the print request, a biometric verification request is sent to the mobile phone, where the biometric includes one or more of a fingerprint, face recognition, iris, and voice. After receiving the biological characteristic verification request, the mobile phone verifies according to the corresponding biological characteristic so as to enable the cloud to determine whether the current mobile terminal user is a legal printer. After the corresponding biological characteristic verification information is input, the mobile phone application sends the biological characteristic verification information and the identification information of the file to be printed to the cloud end, the cloud end checks whether the mobile phone holder has the corresponding printing authority or not according to the biological characteristic verification information and the identification information of the file to be printed, whether the identification information of the file to be printed sent by the mobile phone is consistent with the identification information of the file to be printed sent by the printing equipment or not is judged, and if the identification information of the file to be printed is consistent with the identification information of the file to be printed sent by the printing equipment, the storage is controlled to send the corresponding file to be printed to the printing equipment for printing.
In addition, in order to further improve the confidentiality level of the authority file, a mobile phone holder can also agree with a storage to perform a password verification mode on certain special files, for example, when the special files are printed, the cloud sends a password verification request to the mobile phone, and the mobile phone sends a printing verification password input option of the file to be printed after inputting the biological characteristic verification information. After the user inputs the password, the mobile phone sends the printing password information to the cloud. In this step, the cloud end does not verify whether the printing password information is correct after receiving the printing password information, but directly sends the printing password information to the memory, the printing password information does not verify the identity of a printer or a mobile terminal, but verifies whether the printing password information is matched with a file to be printed, if the printing password information is matched with the file to be printed, the memory permits to call the special file, and if the printing password information is not matched with the file to be printed, the memory calls the low-authority file excluding the special file and sends the low-authority file to the printing equipment. After the memory verifies all the information, the memory establishes connection to the printing equipment and sends the file to be printed for the printing equipment to print. Whether printing is successful or not, the printing device sends the printing request and/or the printing result of the mobile terminal to the cloud end, the cloud end sends the storage to store, and the printing trace of the printing device is cleared after the printing device sends the printing request and/or the printing result.
According to the printing mode, the information safety in the mobile printing process is improved through the triple verification mode of binding the file with the mobile terminal and the user, binding the file with the authority of the mobile terminal and binding the file with the printing password information, the situation that a user with low printing authority in the same organization obtains a file with high printing authority is avoided, and the information leakage risk caused by the loss of the mobile terminal is also avoided. In addition, the printing equipment can normally print all the files only when the user normally holds the mobile terminal, the authority of the file to be printed accords with the corresponding printing authority and the password of the file is verified to be correct. If the user mistakes the mobile terminal, the biological characteristics are not passed, and the printing fails; if the user normally holds the mobile terminal and wants to print the file with the super printing authority, the verification cannot be passed and the printing fails; if the low-authority user normally holds the mobile terminal, but prints the corresponding high-authority file by cracking, forging or transplanting the high printing authority, the printing fails by printing the password information.
In addition, the invention can establish connection with the printing equipment to transmit the file only after all the verifications are passed, and the file transmission is subject to the final identification information of the file to be printed after being checked, thereby avoiding the invasion of the printing equipment end to send the fake identification mode of the file to be printed to the cloud end to steal the secret and improving the safety.
On the basis of the embodiment, the invention is further improved, in order to reduce the confusion printing risk of mobile terminals with different printing authorities, one mobile terminal is only bound with one memory, and each mobile terminal only has one printing authority to clearly determine the printing authority and the memory of the mobile terminal.
On the basis of the above embodiment, the present invention is further improved, in order to save cost, a plurality of mobile terminals may be correspondingly bound to each memory, and a file with a plurality of printing authorities is stored in each memory.
