All technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, unless otherwise defined. The terminology used in the description of the present invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and/or" used herein includes any and all combinations of one or more of the associated listed items.

Some embodiments of the present invention are described in detail below with reference to the accompanying drawings. The characteristics of the following embodiments and examples can be combined with each other without conflict.

1 is a schematic flowchart of a secure printing method according to an embodiment of the present invention. Referring to FIG. 1 , the embodiment provides a secure printing method, which can meet the printing requirements of different users, and can also ensure The security of the file information, specifically, the method includes:

S101: Acquire a file to be printed corresponding to the request to be printed;

The execution entity of the step may be a server, and the specific implementation manner of obtaining the file to be printed may be: the user transmits the to-be-printed request and the to-be-printed file corresponding to the to-be-printed request to the server through the user terminal; or, the server is configured according to The print request initiated by the user at the user terminal is used to obtain a file to be printed from the user terminal. Of course, those skilled in the art may use other methods to obtain a file to be printed, and details are not described herein. In addition, the file to be printed in this embodiment is an electronic file for facilitating transmission between the server and the image forming apparatus, wherein the electronic file may be an original file generated by the user in advance, or the original file may be passed. The data processing unit of the user terminal or the intermediate format data processed by the application installed in the user terminal or the printable data identifiable by the image forming apparatus, wherein the intermediate format data is identifiable between the original document and the image forming apparatus A format file between the printable data, for example, the original file is in the Word format. In this case, the intermediate format data may be a PDF file or an XPS format file, and may of course be other format files that can be conceived by those skilled in the art. , will not repeat them here.

S102: Determine a file security level of the file to be printed;

After the print file is obtained, the print file can be analyzed and processed. Specifically, the storage location, the content information, the feature identifier, and the like of the file to be printed can be obtained, and then the storage location, the content information, the feature identifier, and the like are analyzed and processed. The file security level of the file to be printed may be determined by analyzing the processing result, or the file security level of the file to be printed may be determined according to the user information of the job to be printed or the user terminal information; wherein the file security level may include: a common level , security level, specific, ordinary level can represent the security level of the file to be printed is general, anyone can print the file to be printed; security level can represent that the print file can be formed by the image after satisfying certain conditions The device prints out. Of course, the security level can be further divided into different security levels, such as the first level of security, the second level of security, and the like.

Further, the file security level may also be determined according to a request sent by the user terminal, and specifically includes a common level, a transmission encryption level, a management output level, a security mark level, a security output level, and the like. The transmission encryption level specifically refers to the process in which the user terminal sends the file to be printed to the cloud server, and the cloud server sends the received file to be sent to the image forming apparatus, and the file to be printed is encrypted. The specific encryption algorithm is a common encryption algorithm that is easily conceivable by those skilled in the art, for example, asymmetric encryption, etc., at this time, an asymmetrically encrypted public key is stored in an image forming apparatus (for example, a printer); specifically, when the user When the user terminal sends a transmission encryption request to the server, the cloud server sends the private key stored in the cloud server to the user terminal based on the received transmission encryption request, and the user terminal encrypts the printed file by using the received asymmetrically encrypted private key. And sending the encrypted file to be printed to the cloud server, and the cloud server sends the received file to be sent to a corresponding image forming apparatus (for example, a printer) for printing; the control output level refers to the file to be printed is being When the image forming device outputs, it is necessary to undergo user intervention before the corresponding print can be taken out. The file or control image forming apparatus performs a printing operation, the user intervention includes a user authentication or a user opens a paper cassette of an image forming apparatus (eg, a printer), or other means as would be readily apparent to those skilled in the art; specifically, when the user terminal moves to the cloud When the server sends a print request including the user information, the cloud server determines, according to the received user information, that the security level of the file to be printed is an output management level, that is, the file to be printed needs to be interfered by the user when being output by the image forming apparatus; The mark level refers to adding mark information to a file to be printed by using an application installed in the user terminal, or after the image forming apparatus receives the file to be printed, the image forming apparatus adds mark information to the file to be printed, so that subsequent The output document corresponding to the print file may be traced according to the above-mentioned tag information. Specifically, the user terminal sends a security tag request to the cloud server, and the cloud server determines the security level of the file to be printed as a security mark level based on the security tag request sent by the user. ; The full output level means that the file to be printed can be directly printed and output by the image forming apparatus, but due to the geographical position of the image forming apparatus, the printed document is not easily acquired by other unrelated persons, and therefore, directly by the image forming apparatus The output document is also secure. Specifically, the user terminal sends a security output request to the cloud server, and the cloud server determines the security level of the file to be printed as a security output level based on the security output request sent by the user. It should be additionally noted that various requests sent by the user terminal to the cloud server are initiated based on the user selecting an actual demand in the user terminal application interface.

Certainly, the classification of the file security level is not limited to the above types, and those skilled in the art may also divide the file security level into several levels according to specific design requirements, and details are not described herein again.

S103: determining an image forming apparatus corresponding to a file security level in a plurality of image forming apparatuses configured in advance;

The image forming apparatus may be a printer, a copying machine, or a multi-function printer (MFP) having a scanning/printing function, etc.; for convenience of explanation, the following uses a printer as an image forming apparatus as an example. After determining the file security level, in order to facilitate secure printing operations on files to be printed of different file security levels, a printer corresponding to the file security level may be determined among a plurality of printers pre-stored in the server; that is, the printer may also A plurality of device security levels are included, and a file to be printed with different file security levels has a mapping relationship with a printer of a different device security level, and the cloud server determines an image forming device connected thereto based on the determined security level of the file to be printed. The security level, specifically, when the file security level of the file to be printed is a normal level or a security level, the security level of the corresponding image forming apparatus is a normal level or a security level, and the file security level of the file to be printed is a common level. Transmission encryption Safety class, control the output level, security mark level, the safety output level when one of the corresponding image forming apparatus is also common level, transmission encryption level, control the output level, security mark level, one of the safety output level. For example, a normal-grade file to be printed corresponds to a normal printer, a confidentiality level to be printed file corresponds to a secure printer, and the like.

Further, the security level of the printer may be a general-level printer, a transmission encryption level printer, a control output level printer, a security mark level printer, a security output level printer, etc. Specifically, the transmission encryption level printer refers to when the cloud server is encrypted. When the file to be printed is sent to the printer, the printer has a corresponding decryption function; the control output level printer refers to a printer that needs to perform user intervention to control the printer to print or take out the output document corresponding to the file to be printed; the security mark printer refers to Printers output after the printer output include printers such as watermarks, barcodes, etc. for tracking and tracing the printed documents; secure output level printers are printers in a secure environment, such as a password lock or fingerprint lock. In the room, only some people can enter the room where the printer is located, and get the printout document.

Therefore, when the file security level is the normal level, the corresponding printer is a normal level printer; when the file security level is the transmission encryption level, the corresponding printer is the printer control output level for transmitting the encryption level; when the file security level is the security mark level When the file security level is the control output level, the corresponding printer is the control output level printer; when the file security level is the security output level, the corresponding printer is the safe output level printer.

In addition, when there are multiple printers of the same security level, the server may acquire status information of a plurality of printers corresponding to the file security level, and then automatically send the file to be printed to a certain printer based on the acquired status information of the plurality of printers. For example, the file to be printed is sent to the printer that is idle for printing; in addition, when there are multiple printers of the same security level, one target printer can be determined among the plurality of printers based on the user's selection.

Of course, the classification of the device security level of the image forming apparatus/printer is not limited to the above description, and those skilled in the art may also set the device security level of the image forming apparatus/printer according to specific design requirements. Specifically, Different devices have different security levels and different types of security, so that different printing tasks can be completed according to different security levels of these devices, thereby effectively avoiding information leakage.

S104: Perform a printing operation on the print file by using the determined image forming apparatus.

After the image forming apparatus corresponding to the file security level is determined, the image forming apparatus can be used to perform a printing operation on the print file, wherein the information in the file to be printed can be effectively ensured when the printing operation is performed on the file to be printed. Sex.

The secure printing method provided by this embodiment determines the file security level of the file to be printed, and then determines the image forming apparatus corresponding to the file security level. After determining the image forming apparatus, the image forming apparatus prints the file to be printed. The operation can meet the printing requirements of different users, and can also effectively ensure the security of the file information, and can automatically select the security level of the file to be printed when the image forming apparatus with multiple different security levels is connected to the server. The most matching image forming apparatus performs printing without the user manually selecting an appropriate image forming apparatus for printing, which brings convenience to the user, and also improves the printing efficiency of various files, thereby ensuring the practicability of the secure printing method. It is conducive to the promotion and application of the market.

Levels can include:

S1023: Acquire level selection information input by the user;

Referring to FIG. 10, after obtaining the file to be printed, in order to improve the speed and efficiency of determining the file security level of the file to be printed, a display interface for performing file security level selection may be sent to the user, or When the user clicks on the printing operation, a dialog box pops up for the user to select the security level to print the to-be-printed file. As shown in FIG. 11, the display interface may include multiple file security levels (including normal and hierarchical). 1, level 2, etc.), the user can click the corresponding file security level, for example, you can click level 1, and click the confirmation button, that is, the setting operation of the file level to be printed is completed. At this time, the server can receive the level input by the user. Select the information. Of course, in the display interface, multiple file security levels (including normal, control output, transport encryption, security output, security mark, etc.) can be included.

S1024: Determine a file security level of the file to be printed according to the level selection information.

When the level selection information of the click level 1 is obtained, the file security level corresponding to the level selection information (ie, level 1) can be determined as the file security level of the print file, so that the file security level can be acquired in a timely and effective manner. The file security level of the printed file.

4 is a schematic flowchart 3 of determining a file security level of a file to be printed according to an embodiment of the present invention; and based on the foregoing embodiment, referring to FIG. 1 and FIG. 4, determining a file security level of a file to be printed The third achievable manner is that determining the file security level of the file to be printed may include:

S1025: Acquire storage information of the file to be printed;

The storage information is storage location information of the file to be printed on a terminal such as a mobile phone or a computer. Specifically, when the file to be printed stored on the terminal is sent to the cloud server by using the terminal application, the terminal application can obtain the file to be printed. The storage location information stored in the terminal, and the corresponding storage location information is sent to the server, thereby obtaining storage information of the file to be printed.

S1026: Determine a file security level of the file to be printed according to the storage information.

After the storage location of the file to be printed is obtained, the storage location may be analyzed. Specifically, the storage location may be compared with a preset standard storage location to determine a standard storage location corresponding to the storage location. And determining the security level corresponding to the standard storage location as the file security level of the file to be printed; for example, the storage location of the file to be printed 1 and the file to be printed 2 are: Customer Service Department - Location 1, Legal Department - Location 3. At this time, through the analysis and judgment of the customer service department-position 1, it is determined that the standard storage location corresponding to the storage location is the customer service department, and the security level corresponding to the customer service department-position 1 is the ordinary level, so that it can be determined The file security level of the print file 1 is a normal level; and through the analysis of the Legal Department-Location 3, it is determined that the standard storage location corresponding to the storage location is the legal department, and the legal department-position 3 corresponds to the security level of two. The level of security is determined so that the file security level of file 1 to be printed is determined to be a secondary security level.

Of course, those skilled in the art can further determine the file security level of the file to be printed by combining different work departments and different folders under the same department; in addition, determining the file to be printed by storing other types of information in the information. The specific implementation process of the file security level is similar to the implementation process of determining the file security level of the file to be printed according to the storage location, and details are not described herein again.

The security level of the file to be printed can be quickly and accurately determined based on the storage location information of the file to be printed in the terminal, and the user does not need to manually determine the security level of the file to be printed, thereby providing convenience to the user.

FIG. 5 is a schematic flowchart 4 of determining a file security level of a file to be printed according to an embodiment of the present invention; and referring to FIG. 1 and FIG. 5 on the basis of the foregoing embodiment, it is known that there are different roles in an enterprise. Staff, and staff of different roles have different working rights, and printing permission as a kind of work right will also be different because of the role of the staff. Therefore, it is safe to determine the file to be printed. In terms of level, the fourth achievable manner is that the file security level of the file to be printed may include:

S1027: Acquire identity information of a user who sends a request to send a print;

S1028: Determine a file security level of the file to be printed according to the identity information of the user.

Specifically, the process of obtaining the identity information of the user and determining the file security level of the file to be printed according to the identity information of the user may be as follows:

After the user logs in to the cloud server through the application of the user terminal, the cloud server determines the user permission level based on the user name information registered by the user, so as to further determine the security level of the corresponding file to be printed.

In the second method, after the user logs in to the cloud server through the application of the user terminal, the user terminal application acquires the ID information of the terminal, and sends the ID information of the terminal to the cloud server, and the cloud server is based on the obtained user terminal. The ID determines the permission level of the user, thereby further determining the security level of the corresponding file to be printed;

Method 3: After the user logs in to the cloud server through the application of the terminal, the terminal application sends a print request to the cloud server based on the login user name and the login password, and the print request also includes the ID of the user or the ID of the terminal, and the cloud server is based on The received user ID and terminal ID determine the security level of the file to be printed corresponding to the print request. Certainly, those skilled in the art may also use other methods to obtain the identity information of the user, as long as the accuracy and reliability of the identity information of the user can be ensured, and details are not described herein again.

For example, you can set the security level of the files to be printed sent by some client users (PC1, PC2, etc.) to the normal level, and the security level of the files to be printed sent by some other clients (PC3, PC4) is the transmission encryption level. Or, it is possible to set a certain file group (for example, a research and development work group) to send a file to be printed as an output management level, and other (sales work group) to send a file to be printed as a normal level. For example, the user's privilege can be divided into: ordinary employee privilege, group leader privilege, and manager privilege according to the user's identity information. The file security level of the employee's file to be printed is a common level. You can use a normal printer to print; the file security level of the employee's to-be-printed file is a first-level security level, and then the encrypted security printer is used for printing. The file security level of the employee with the manager-level authority is secondary security. Levels, which in turn can be printed using a secure, manually controlled, secure printer.

By obtaining the identity information of the user and analyzing and identifying the identity information of the user, the file security level of the file to be printed can be determined according to the analysis and identification result, and the printer can be printed by using the printer of different security levels, thereby effectively satisfying the requirement. The different printing needs of different users, and also ensure the security and reliability of the printed file information, further improve the stability and reliability of the use of the secure printing method, and provide convenience for the user because the user does not need to manually set the security level of the file to be printed.

FIG. 6 is a schematic flowchart 5 of determining a file security level of a file to be printed according to an embodiment of the present invention; and referring to FIG. 1 and FIG. 6 , for determining a file security level of a file to be printed, according to the foregoing embodiment. The fifth achievable manner is that determining the file security level of the file to be printed may include:

S1029: Send the file to be printed to the approver for approval;

S10210: Determine a file security level of the file to be printed according to the approval result.

When the file to be printed is sent to the approver for approval, at least a part of the file to be printed (including: partial information, extracted keyword information or all information, etc.) may be sent to the approver for approval; specifically, the server The file to be printed can be sent to the designated approver for review. The auditor is responsible for judging whether the document can be printed and at what security level is printed; determining the security level of the file to be printed based on the approval result, thereby effectively ensuring the file to be printed The accuracy of the file security level is determined.

FIG. 7 is a schematic flowchart 6 of determining a file security level of a file to be printed according to an embodiment of the present invention; FIG. 8 is a flowchart of comparing a file to be printed with a preset standard print file of different security levels according to an embodiment of the present invention; Schematic diagram of the process; based on the foregoing embodiment, with reference to FIGS. 1 and 7-8, the sixth achievable manner for determining the file security level of the file to be printed is that the file to be printed is determined. File security levels can include:

S10211: analyzing and comparing the file to be printed with a standard print file of a different security level set in advance;

S10212: Determine a security level corresponding to the standard print file that matches the file to be printed as a file security level of the file to be printed.

Specifically, after the user terminal sends the file to be printed to the server, the server compares the file to be printed with a standard file in a pre-stored standard file library, where the server stores the standard file and its corresponding security. Print level. When there is a standard file in the standard file library that is the same as the file to be printed, it is determined that the security level of the file to be printed is the security print level corresponding to the aforementioned standard file. Otherwise, the security level of the file to be printed is determined to be Normal print level.

By comparing the file to be printed with the standard file stored in the cloud server, the security level of the file to be printed is determined, and the user does not need to manually set the security level of the file to be printed, which brings convenience to the user.

Specifically, in this embodiment, a person skilled in the art can set according to specific design requirements, wherein an implementation manner is that the file to be printed is compared with a standard print file of a different security level set in advance. Includes the following substeps:

S102111: Acquire a file feature value of a file to be printed;

After the file to be printed is sent to the cloud server by the terminal, the cloud server analyzes the file to be printed. Specifically, the file feature value of the file to be printed can be extracted. The file feature value may be an MD5 value or a file metadata, where MD5 is an abbreviation of Message-Digest-Algorithm 5; for a file feature value, after the file to be printed is generated, There will be a unique MD5 value or file metadata, so the print file can be analyzed and processed according to the obtained file feature value.

S102112: analyzing and comparing the file feature value with a standard file feature value corresponding to the standard print file;
