It will be appreciated by those skilled in the art that the terminal structure shown in fig. 1 is not limiting of the terminal and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.

In the terminal shown in fig. 1, the terminal calls a file transfer program stored in a memory 1005 through a processor 1001 and performs operations in the respective embodiments of the file transfer method described below.
Based on the hardware structure, the embodiment of the file transmission method is provided.
Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a file transfer method according to the present invention, where the method includes:
step S10, if a transmission instruction triggered by a target terminal based on a target file is detected, acquiring target terminal information of the target terminal, and generating first watermark information of the target file based on the target terminal information;
and step S20, the target file carrying the first watermark information is sent to a receiving terminal corresponding to the transmission instruction.
The file transmission method is applied to file transmission equipment, the file transmission equipment can be mobile terminals such as mobile phones and tablet computers, and can also be fixed terminals such as computers, and for convenience in description, the file transmission equipment is briefly described by the terminals. In the implementation, the enterprise only needs to install a program for executing the file transmission method on an internal terminal, such as a computer, so that the internal terminal of the enterprise can realize the file transmission method, if staff sends out the target file of the enterprise through the terminal, the terminal can acquire terminal information and generate watermark information indicating that the target file is sent out from the current terminal, and then the target file carrying the watermark information is sent out, so that the target file received by the receiving terminal also contains the watermark information, and if the target file is leaked, a leaked person can be found according to the watermark information.
The following will explain each step in detail:
step S10, if a transmission instruction triggered by a target terminal based on a target file is detected, acquiring target terminal information of the target terminal, and generating first watermark information of the target file based on the target terminal information.
In this embodiment, if the detection target terminal is based on a transmission instruction triggered by the target file, that is, when an employee wants to transmit the target file on the target terminal, target terminal information of the target terminal is acquired, where the target terminal information includes work number information of the employee corresponding to the target terminal and id information of the target terminal, and then, based on the target terminal information, first watermark information of the target file is generated, and since the watermark generation method is mature, it is necessary to describe that the finally generated first watermark information includes the work number information and the id information, so that secret leakage tracing can be performed according to the work number information and the id information.
Further, in another embodiment, the first watermark information comprises a hidden watermark, and thus, in another embodiment, step S10 comprises:
step a1, if a transmission instruction triggered by a target terminal based on a target file is detected, determining the page type of the target file;
in another embodiment, if the transmission instruction triggered by the target terminal based on the target file is detected, the page type of the target file is determined first, and it should be noted that in another embodiment, the page of the target file is divided into a content area and a blank area, where the content area may be text or a picture, and thus the page type includes content and blank.
Step a2, if the page type is content, acquiring target terminal information of the target terminal, and generating a hidden watermark corresponding to the target terminal information;
in another embodiment, if the page type of the target file is determined to be content, target terminal information of the target terminal is obtained, and an implicit watermark corresponding to the target terminal information is generated. It will be appreciated that, since the content, such as a text or a picture, is displayed in the content area, if the explicit watermark is generated, the reading effect of the target file will be affected, and thus, in another embodiment, the implicit watermark is generated for the content area.
It should be noted that, the hidden watermark refers to a watermark which cannot be observed by a normal naked eye or a normal angle, and the watermark can be seen only by a special observation tool or a special angle, and the principle is visual spoofing, such as a watermark which can be seen only by being close to a screen on the left side of the screen of the terminal. In another embodiment, the hidden watermark may be a hidden code, and a corresponding decoding procedure is required to display the hidden watermark, which is not limited herein.
And a3, adding the hidden watermark in a content area corresponding to the content.
Finally, a hidden watermark is added to the content area corresponding to the content, and the specific adding mode is not limited herein because the hidden watermark is a hidden watermark.
When the hidden watermark is added, the hidden watermark and the content of the target file, such as a text, a picture and the like, are positioned on the same display layer, so that leakage personnel can be prevented from removing the hidden watermark by removing the display layer.
Further, in another embodiment, the first watermark information includes an explicit watermark, and after step a1, the file transfer method further includes:
step a4, if the page type is blank, acquiring target terminal information of the target terminal, and generating an explicit watermark corresponding to the target terminal information;
in another embodiment, if the page type of the target file is determined to be blank, that is, a blank area of the page in the target file, target terminal information of the target terminal is obtained, and an explicit watermark corresponding to the target terminal information is generated, wherein the difference between the explicit watermark and the implicit watermark is one normally visible one normally invisible one.
And a step a5, adding the dominant watermark in a blank area corresponding to the blank.
Finally, the explicit watermark is added to the blank area corresponding to the blank, and the specific adding mode can be an embedding mode, the explicit watermark is embedded into the blank area of the target file, and the explicit watermark and the content of the target file, such as characters, pictures and the like, can be located on the same display layer or different display layers, and in this embodiment, the explicit watermark and the content of the target file are preferably located on the same display layer.
In another embodiment, the hidden watermark and the dominant watermark can be added at the same time, that is, in the page of the target file, the hidden watermark is added to the content area with the content, and the dominant watermark is added to the blank area, so that the dominant watermark mainly plays a confusing role, and the leakage personnel concentrate on the removal of the dominant watermark and ignore the hidden watermark.
And step S20, the target file carrying the first watermark information is sent to a receiving terminal corresponding to the transmission instruction.
In this embodiment, finally, the target file carrying the first watermark information is sent to the receiving terminal corresponding to the transmission instruction, where the receiving terminal may be a terminal of the same enterprise as the target terminal, or may be a terminal of a different enterprise from the target terminal. If the receiving terminal is a terminal of the same enterprise to which the target terminal belongs, the current transmission is internal transmission, if the receiving terminal is a terminal of a different enterprise to which the target terminal belongs, the current transmission is indicated that the leakage risk of the target file of the enterprise is present by the staff, if the leakage situation of the target file exists, the target file can be obtained, and the user can know the leakage by looking at the watermark information of the target file.
If the leakage file exists currently, the watermark information of the leakage file can be checked to determine who is leaked, if A sends the target file to B, B sends the target file to C, C possibly sends the target file to other people, the watermark information of the leakage file indicates B, the leakage file is determined to be originally leaked by B, and C and B possibly belong to different enterprises.
In this embodiment, if a transmission instruction triggered by a target terminal based on a target file is detected, target terminal information of the target terminal is obtained, and first watermark information of the target file is generated based on the target terminal information; and sending the target file carrying the first watermark information to a receiving terminal corresponding to the transmission instruction. When the target file is transmitted, the watermark information corresponding to the target terminal is generated, the target file carrying the watermark information is sent out, and if the target file is leaked, the position from which the target file is leaked can be known according to the watermark information, so that the traceability of the target file is realized.
Further, based on the first embodiment of the file transfer method of the present invention, a second embodiment of the file transfer method of the present invention is provided.
The second embodiment of the file transfer method differs from the first embodiment of the file transfer method in that step S10 includes:
step b1, if a transmission instruction triggered by a target terminal based on a target file is detected, determining whether the target file is an original created file;
and b2, if yes, acquiring target terminal information of the target terminal, and generating first watermark information of the target file based on the target terminal information.
In the process of generating the watermark, the embodiment needs to determine whether the target file is the original created file, so that different parameters are selected to generate the watermark information, and the generated watermark information is reliable and traceable.
The following will explain each step in detail:
and b1, if a transmission instruction triggered by the target terminal based on the target file is detected, determining whether the target file is an original created file.
In this embodiment, if a transmission instruction triggered by the target terminal based on the target file is detected, it is first determined whether the target file is an original created file, where the original created file refers to a file edited and created by the current employee at the target terminal, that is, the target terminal is the creator of the target file, so that it can be determined whether the target file is an original created file by determining the creator of the current target file. Specifically, if the creator of the target file is the target terminal, that is, the target file is created by an employee on the target terminal, determining that the target file is an original created file; if the creator of the target file is not the target terminal, that is, the target file is sent or transferred by other terminals received by the target terminal, it is determined that the target file is not the original created file.
And b2, if yes, acquiring target terminal information of the target terminal, and generating first watermark information of the target file based on the target terminal information.
In this embodiment, if it is determined that the target file is an original creation file, target terminal information of the target terminal is obtained, and first watermark information of the target file is generated according to the target terminal information, that is, after it is determined that the target file is the original creation file, the target terminal information of the target terminal is selected as a generation parameter of the watermark information; if the target file is not the original created file, other information is selected as the generation parameter of the watermark information.
Further, in another embodiment, step b2 includes:
if yes, acquiring target terminal information of the target terminal and receiving terminal information corresponding to the transmission instruction;
in this step, if it is determined that the target file is the original creation file, target terminal information of the target terminal and receiving terminal information corresponding to the transmission instruction are acquired, where in this embodiment, the receiving terminal includes id information of the receiving terminal.
And generating first watermark information of the target file based on the target terminal information and the receiving terminal information.
In this step, the first watermark information of the target file is generated according to the target terminal information and the receiving terminal information, that is, the generating parameters of the first watermark information include the target terminal information and the receiving terminal information, so that it is possible to know who the first secret leakage object is, that is, to whom the secret leakage is, in addition to follow up who the secret leakage is according to the watermark information.
Further, in another embodiment, after step b1, the file transfer method further includes:
step b3, if not, acquiring target terminal information of the target terminal and second watermark information carried by the target file, and generating third watermark information of the target file based on the target terminal information, the receiving terminal information and the second watermark information;
in another embodiment, if it is determined that the target file is not the original created file, it is indicated that the target file is sent or transferred by another terminal, where the target file in principle has watermark information, that is, when the other terminal sends the target file to the target terminal, the second watermark information is generated, so that the target terminal information of the target terminal and the second watermark information carried by the target terminal need to be acquired, and thus, according to the target terminal information, the receiving terminal information and the second watermark information, third watermark information indicating that the target terminal sends the third watermark information is generated.
If the target file does not carry the second watermark information, the third watermark information does not need to be generated, that is, if the target file is a file created at a terminal of an enterprise, the watermark information is generated in the transmission process in principle, if the target file is a file copied back from outside the enterprise, the target file does not belong to an enterprise confidential file in principle, so the target file does not have watermark information, and the watermark does not need to be generated in the transmission process.
And b4, sending the target file carrying the third watermark information to a receiving terminal corresponding to the transmission instruction.
In another embodiment, the target file carrying the third watermark information is finally sent to the receiving terminal corresponding to the transmission instruction, which indicates that the target file is generated by the target terminal, and since the generation parameter of the third watermark information includes the second watermark information, it is possible to trace back where the target terminal is received.
Further, in another embodiment, step b3 includes:
if not, acquiring target terminal information of the target terminal and second watermark information carried by the target file, and determining whether the target terminal information meets the second watermark information;
in another embodiment, if it is determined that the target file is not the original created file, it is indicated that the target file is sent or transferred by another terminal, and the target file at this time basically includes watermark information generated by another terminal, so as to obtain target terminal information of the target terminal and second watermark information carried by the target file, and determine whether the target terminal information satisfies the second watermark information.
It should be noted that, the second watermark information in this embodiment is generated by the previous terminal according to the terminal information of the previous terminal and the target terminal information of the target terminal (the previous terminal is the creator of the target file), that is, the target terminal is the receiving terminal in the last transmission.
Therefore, it may be determined whether the target terminal information satisfies the second watermark information, that is, when the a terminal sends the target file to the B terminal, the second watermark information is generated according to the terminal information of the a terminal and the B terminal, and when the B terminal sends the target file to the C terminal, it is required to determine whether the terminal information of the B terminal satisfies the second watermark information, where if the second watermark information includes the target terminal information, it is determined that the target terminal information satisfies the second watermark information. The method is to avoid the false impression that when the A terminal sends the target file to the B terminal, staff corresponding to the B terminal copies the target file at the B terminal, and sends the target file to the C terminal at the D terminal, and the false impression is sent to the D terminal.
And if so, generating third watermark information of the target file based on the target terminal information, the receiving terminal information and the second watermark information.
If yes, the fact that the last terminal is sent to the target terminal in a targeted mode is indicated, and the target terminal is authorized to send the targeted terminal to other receiving terminals is indicated, so that third watermark information of the target file is generated based on the targeted terminal information, the receiving terminal information and the second watermark information during transmission.
Further, if the file is not satisfied, it is indicated that the target file may be copied from another terminal, and the transmission of the target file is prohibited.
If the information is not satisfied, the camera of the target terminal is started to acquire the face information of the current operator, the work number information of the current operator is determined based on the face information, and third watermark information is generated based on the work number information, the target terminal information and the receiving terminal information.
It can be understood that the terminal a sends the target file to the terminal B, the terminal B fails and cannot send the target file to the terminal C, and at this time, the staff of the terminal B is likely to send the target file by other devices, but needs to avoid the back-pot of other terminals, so that at this time, the face information of the staff can be obtained, and thus the work number information of the staff is determined in the enterprise information base, and the third watermark information is smoothly generated.
In the process of generating the watermark, the embodiment needs to determine whether the target file is the original created file, so that different parameters are selected to generate the watermark information, and the generated watermark information is reliable and traceable.
The invention also provides a file transmission device. The file transmission device of the present invention comprises:

Further, the first watermark information includes an explicit watermark, and the generating module is further configured to:
if the page type is blank, acquiring target terminal information of the target terminal, and generating an explicit watermark corresponding to the target terminal information;
and adding the dominant watermark in a blank area corresponding to the blank.

the sending module is further configured to:
and sending the target file carrying the third watermark information to a receiving terminal corresponding to the transmission instruction.
