Fig. 1 shows a schematic diagram of a service device 1 and a user device 2 for file transfer according to an aspect of the present invention.
Wherein the service apparatus 1 comprises: a device (hereinafter referred to as "one-to-one device 11") for acquiring a signaling request sent by a user equipment, wherein the signaling request is generated according to a file transmission position; means (hereinafter referred to as "a second device 12") for generating a first signaling according to the signaling request, in combination with the user identification information and the signaling request time information; means for transmitting the first signaling to the user equipment (hereinafter referred to as "a third means 13"); means (hereinafter, referred to as "a-four means 14") for receiving a file transfer request sent by the user equipment, wherein the file transfer request includes a file upload request and/or a file download request, and the file transfer request corresponds to the file transfer location; means (hereinafter, referred to as "fifth means 15") for determining authentication information corresponding to the file transfer request, wherein the authentication information includes whether the first signaling already corresponds to a transferred file; means (hereinafter, referred to as "a sixth means 16") for allowing the ue to transmit the file based on the first signaling if the authentication information is legal, wherein the legal authentication information includes that the first signaling does not correspond to the transmitted file.
The user equipment 2 comprises: means for generating a signaling request based on a file transfer location (hereinafter referred to as "two-to-one means 21"); a device (hereinafter referred to as "second device 22") configured to send the signaling request to a service device and obtain a first signaling sent by the service device, where the first signaling is generated according to the signaling request and by combining user identification information and signaling request time information; means (hereinafter referred to as "two-three means 23") for sending a file transfer request to the service device, wherein the file transfer request includes a file upload request and/or a file download request, and the file transfer request corresponds to the file transfer location; and a device (hereinafter, referred to as "second-fourth device 24") configured to transmit a file based on the first signaling if the authentication information of the service device is legal, where the legal authentication information includes that the first signaling does not correspond to the transmitted file.
The first device 21 generates a signaling request according to the file transmission position.
Specifically, when the user logs in a page corresponding to the file transmission by using the user equipment, or clicks an input box corresponding to the file transmission on the page, the two-in-one device 21 generates a signaling request according to the file transmission position.
The document transmission location includes, but is not limited to, a page corresponding to the document transmission (e.g., a document uploading page), or an input box for document transmission on the page (e.g., a specific document is uploaded in the input box of the specific location, the page may include other input boxes, and the other input boxes may correspond to other document transmissions or non-document transmissions). Those skilled in the art will appreciate that the file transfer location corresponds to the user, such as different user corresponding file transfer pages or different specific input boxes for file transfer.
Wherein the signaling request is used to request the serving device 1 to generate a first signaling for file transfer.
The second device 22 sends the signaling request to the service device 1 according to a predetermined communication protocol based on a predetermined communication interface, and correspondingly, the one-to-one device 11 of the service device 1 obtains the signaling request sent by the user equipment 2 according to a predetermined communication protocol based on a predetermined communication interface, where the signaling request is generated according to a file transmission location.
Then, the second device 12 generates a first signaling according to the signaling request, in combination with the user identification information and the signaling request time information.
Specifically, the second device 12 generates the first signaling according to the signaling request by combining the user identification information (one or more user identification information such as a user ID, a user equipment ID, and a user IP address) corresponding to the user equipment and the signaling request time information based on the file transmission location corresponding to the signaling request.
The one-third device 13 sends the first signaling to the user equipment 2 according to a predetermined communication protocol based on a predetermined communication interface; correspondingly, the second device 22 of the user equipment 2 acquires the first signaling sent by the service equipment based on the predetermined communication interface according to the predetermined communication protocol, wherein the first signaling is generated according to the signaling request and by combining the user identification information and the signaling request time information.
The two-three device 23 of the user equipment 2 sends a file transmission request to the service equipment 1 according to a preset communication protocol and based on a preset communication interface; correspondingly, a fourth device 14 of the service device 1 receives the file transmission request sent by the user device based on a predetermined communication interface according to a predetermined communication protocol; the file transmission request comprises a file uploading request and/or a file downloading request, and the file transmission request corresponds to the file transmission position.
The file transmission request is a file transmission request corresponding to the file transmission position, and includes a file uploading request and/or a file downloading request. If the file transmission request is a file upload request, the file transmission request may be: requesting to upload a certain file at the file transmission position (for example, clicking a certain upload key to upload a certain file, where the upload key is located or a corresponding upload text box is the file transmission position); if the file transmission request is a file download request, the file transmission request may be: and requesting to download a certain file at the file transmission position (for example, clicking a certain download key to download a certain file, wherein the position of the download key is the file transmission position).
Herein, the files include, but are not limited to, documents, pictures, videos, other multimedia files, and the like.
The first device 15 determines the authentication information corresponding to the file transmission request, where the authentication information includes whether the first signaling already corresponds to the transmitted file.
Specifically, the first five device 15 checks whether the first signaling is already used for transmitting other files and has successfully transmitted: here, if the file transfer request is an upload request, verifying whether the first signaling already corresponds to an uploaded file; and if the file transmission request is a downloading request, verifying whether the first signaling is used for downloading the file data corresponding to the file transmission request.
It will be understood by those skilled in the art that the authentication information may also be verified by the user identification information of the file transfer request, the transmission mode of the file transfer request (e.g., whether to transmit in a secure mode), etc., to determine whether the file transfer request is legitimate.
If the authentication information is legal, the sixth device 16 allows the ue 2 to transmit the file based on the first signaling; accordingly, the second four device 24 of the user equipment 2 transmits the file based on the first signaling; wherein the legal authentication information includes that the first signaling does not correspond to a transmitted file.
Specifically, if the first signaling does not correspond to a transmitted file, the authentication information is determined to be legal; preferably, if the authentication information further includes other information, for example, user identification information of the file transfer request, a transfer method of the file transfer request, and the like, the validity of the authentication information is determined based on a validity condition corresponding to the information.
The one-sixth means 16 then allow the two-fourth means 24 of the user equipment 2 to transmit a file based on the first signaling, the transmitted file corresponding to the first signaling, the first signaling being associated with a transmitted file after transmission.
In other words, if the first signaling already corresponds to a transmitted file, the authentication information is considered to be illegal, so that the service device 1 no longer allows the user equipment 2 to transmit based on the first signaling.
That is, whether the file is uploaded or downloaded, the file transmission in the present invention only allows one successful transmission, after one successful transmission, the first signaling is associated with a transmitted file, and the present invention no longer allows a second transmission based on the first signaling.
Preferably, the authentication information further includes whether the transmission request time information corresponding to the first signaling exceeds a timeout threshold; the legitimate authentication information includes that the first signaling does not correspond to a transmitted file and does not exceed a timeout threshold.
In particular, the timeout threshold may be determined based on one or more of the following: the file transmission request is determined according to the attribute information of the user equipment or the current application of the user, and the like, and is determined according to the characteristics (such as security level, confidentiality requirement and the like) of the file corresponding to the file transmission request.
The timeout threshold may be a length of time, such as 10 minutes; or may be a time node, such as every hour, etc.
For example, if the signaling request time information is 10 minutes from 10 to 10 minutes, and the timeout threshold is 10 minutes, the transmission request time information from 10 to 20 minutes all belong to the time range not exceeding the timeout threshold, and the transmission request time information after 10 to 20 minutes is considered to belong to the time range exceeding the timeout threshold.
When the authentication information includes whether the transmission request time information corresponding to the first signaling exceeds a timeout threshold, the legal authentication information includes that the first signaling does not correspond to a transmitted file and does not exceed the timeout threshold.
In other words, the first signaling allows only one successful file transfer request at the file transfer location within a certain timeout threshold; if the first signaling already corresponds to a transmitted file, the file transmission request is considered to be illegal; if the file transmission request exceeds a time threshold, whether the first signaling corresponds to a transmitted file or not is judged that the file transmission request is illegal; and only when the first signaling does not correspond to the transmitted file and does not exceed a timeout threshold and is simultaneously satisfied, the authentication information is determined to be legal and the file transmission is allowed.
Further, if the transmission request time information corresponding to the first signaling exceeds the timeout threshold, the signaling request may be regenerated, so as to generate a new signaling for the file transmission request.
Preferably, the service device 1 further comprises a device (hereinafter referred to as "a seven device", not shown) for providing a security prompt message to the user if the first signaling corresponds to a plurality of file transfer requests within the timeout threshold.
Specifically, a seventh device of the service device 1 continuously interacts with the user device 2 to obtain a file transmission request sent by the user device 2; and if the first signaling corresponds to a plurality of file transmission requests within the overtime threshold, the file transmission corresponding to the file transmission position is considered to be risky, so that safety prompt information is provided for a user through the user equipment.
The safety prompting information includes but is not limited to text prompting, prompting of suggested operation and the like.
Preferably, the user equipment 2 further comprises a device (hereinafter referred to as "twenty-five device", not shown) for providing a security prompt message to the user if the first signaling corresponds to a plurality of file transfer requests within the timeout threshold.
Specifically, the second and fifth devices of the user equipment 2 continuously monitor the interface corresponding to the file transmission position to obtain one or more file transmission requests that may be generated; and if the first signaling corresponds to a plurality of file transmission requests within the overtime threshold, the file transmission corresponding to the file transmission position is considered to be risky, so that safety prompt information is provided for a user.
Preferably, when the file transmission request includes a file uploading request, the user equipment 2 further includes a device (hereinafter referred to as "two-six device", not shown) for caching the uploaded file as a first file.
Specifically, when the file transmission request includes a file upload request, the user equipment 2 caches the uploaded file as a first file, and the first file is associated with the file upload request. The first file may be a preview version of the uploaded file.
For example, if the file is a picture, the first file may be a thumbnail of the picture; if the file is a document, the first file can be a document abstract; if the file is a video, the first file can be a video clip or a video screenshot; if the file is audio, the first file may be a excerpted segment of the audio (e.g., audio of the previous few seconds).

And if the user equipment comprises the first file, the twenty-ninth device directly calls the first file in the user equipment and displays the first file to the user.
In other words, the user equipment no longer interacts with the service equipment, so that the uploaded file is prevented from being acquired in a network transmission mode, and the uploaded file is directly viewed in the user equipment.
It should be understood by those skilled in the art that, if the user equipment does not include the first file, the user equipment may interact with the service equipment again based on the method in the present invention to obtain the uploaded file sent by the service equipment (i.e., perform a file downloading operation).

FIG. 2 illustrates a flow diagram of a method for file transfer in accordance with another aspect of the subject invention.
In step S1, the ue generates a signaling request according to a file transmission location, and sends the signaling request to the service device; in step S2, the service device generates a first signaling according to the signaling request, in combination with the user identification information and the signaling request time information, and sends the first signaling to the user device; in step S3, the user device sends a file transfer request to the service device, where the file transfer request includes a file upload request and/or a file download request, and the file transfer request corresponds to the file transfer location; in step S4, the service device obtains the file transmission request, and determines authentication information corresponding to the file transmission request, where the authentication information includes whether the first signaling already corresponds to a transmitted file; in step S5, if the authentication information is legal, the service device allows the ue to transmit a file based on the first signaling, where the legal authentication information includes that the first signaling does not correspond to the transmitted file.
In step S1, the user equipment 2 generates a signaling request according to the file transfer location.
Specifically, when a user logs in a page corresponding to file transmission by using the user equipment 2, or clicks an input box corresponding to file transmission on the page, the user equipment 2 generates a signaling request according to a file transmission position.
The document transmission location includes, but is not limited to, a page corresponding to the document transmission (e.g., a document uploading page), or an input box for document transmission on the page (e.g., a specific document is uploaded in the input box of the specific location, the page may include other input boxes, and the other input boxes may correspond to other document transmissions or non-document transmissions). Those skilled in the art will appreciate that the file transfer location corresponds to the user, such as different user corresponding file transfer pages or different specific input boxes for file transfer.
Wherein the signaling request is used to request the serving device 1 to generate a first signaling for file transfer.
Then, in step S1, the user equipment 2 sends the signaling request to the service equipment 1 according to a predetermined communication protocol based on a predetermined communication interface, and accordingly, the service equipment 1 obtains the signaling request sent by the user equipment 2 according to a predetermined communication protocol based on a predetermined communication interface, where the signaling request is generated according to a file transmission location.
In step S2, the service device 1 generates a first signaling according to the signaling request, in combination with the user identification information and the signaling request time information.
Specifically, in step S2, the service device 1 generates the first signaling according to the signaling request by combining the user identification information (one or more types of user identification information such as a user ID, a user device ID, and a user IP address) corresponding to the user device and the signaling request time information based on the file transmission location corresponding to the signaling request.
Then, in step S2, the service device 1 sends the first signaling to the user device 2 according to a predetermined communication protocol based on a predetermined communication interface; correspondingly, the user equipment 2 acquires the first signaling sent by the service equipment according to a predetermined communication protocol and based on a predetermined communication interface, wherein the first signaling is generated according to the signaling request and by combining the user identification information and the signaling request time information.
In step S3, the user device 2 sends a file transfer request to the service device 1 based on a predetermined communication interface according to a predetermined communication protocol; accordingly, in step S3, the service device 1 receives the file transfer request sent by the user device based on a predetermined communication interface according to a predetermined communication protocol; the file transmission request comprises a file uploading request and/or a file downloading request, and the file transmission request corresponds to the file transmission position.
The file transmission request is a file transmission request corresponding to the file transmission position, and includes a file uploading request and/or a file downloading request. If the file transmission request is a file upload request, the file transmission request may be: requesting to upload a certain file at the file transmission position (for example, clicking a certain upload key to upload a certain file, where the upload key is located or a corresponding upload text box is the file transmission position); if the file transmission request is a file download request, the file transmission request may be: and requesting to download a certain file at the file transmission position (for example, clicking a certain download key to download a certain file, wherein the position of the download key is the file transmission position).
Herein, the files include, but are not limited to, documents, pictures, videos, other multimedia files, and the like.
In step S4, the service device 1 determines authentication information corresponding to the file transfer request, where the authentication information includes whether the first signaling already corresponds to the transferred file.
Specifically, in step S4, the serving device 1 checks whether the first signaling has been used for transmitting other files and has successfully transmitted by checking the first signaling: here, if the file transfer request is an upload request, verifying whether the first signaling already corresponds to an uploaded file; and if the file transmission request is a downloading request, verifying whether the first signaling is used for downloading the file data corresponding to the file transmission request.
It will be understood by those skilled in the art that the authentication information may also be verified by the user identification information of the file transfer request, the transmission mode of the file transfer request (e.g., whether to transmit in a secure mode), etc., to determine whether the file transfer request is legitimate.
If the authentication information is valid, in step S5, the service device 1 allows the user equipment 2 to transmit a file based on the first signaling; accordingly, the user equipment 2 transmits a file based on the first signaling; wherein the legal authentication information includes that the first signaling does not correspond to a transmitted file.
Specifically, if the first signaling does not correspond to a transmitted file, the authentication information is determined to be legal; preferably, if the authentication information further includes other information, for example, user identification information of the file transfer request, a transfer method of the file transfer request, and the like, the validity of the authentication information is determined based on a validity condition corresponding to the information.
The serving device 1 then allows the user device 2 to transmit a file based on the first signaling, the transmitted file corresponding to the first signaling, the first signaling being associated with a transmitted file after transmission.
In other words, if the first signaling already corresponds to a transmitted file, the authentication information is considered to be illegal, so that the service device 1 no longer allows the user equipment 2 to transmit based on the first signaling.
That is, whether the file is uploaded or downloaded, the file transmission in the present invention only allows one successful transmission, after one successful transmission, the first signaling is associated with a transmitted file, and the present invention no longer allows a second transmission based on the first signaling.
Preferably, the authentication information further includes whether the transmission request time information corresponding to the first signaling exceeds a timeout threshold; the legitimate authentication information includes that the first signaling does not correspond to a transmitted file and does not exceed a timeout threshold.
In particular, the timeout threshold may be determined based on one or more of the following: the file transmission request is determined according to the attribute information of the user equipment or the current application of the user, and the like, and is determined according to the characteristics (such as security level, confidentiality requirement and the like) of the file corresponding to the file transmission request.
The timeout threshold may be a length of time, such as 10 minutes; or may be a time node, such as every hour, etc.
For example, if the signaling request time information is 10 minutes from 10 to 10 minutes, and the timeout threshold is 10 minutes, the transmission request time information from 10 to 20 minutes all belong to the time range not exceeding the timeout threshold, and the transmission request time information after 10 to 20 minutes is considered to belong to the time range exceeding the timeout threshold.
When the authentication information includes whether the transmission request time information corresponding to the first signaling exceeds a timeout threshold, the legal authentication information includes that the first signaling does not correspond to a transmitted file and does not exceed the timeout threshold.
In other words, the first signaling allows only one successful file transfer request at the file transfer location within a certain timeout threshold; if the first signaling already corresponds to a transmitted file, the file transmission request is considered to be illegal; if the file transmission request exceeds a time threshold, whether the first signaling corresponds to a transmitted file or not is judged that the file transmission request is illegal; and only when the first signaling does not correspond to the transmitted file and does not exceed a timeout threshold and is simultaneously satisfied, the authentication information is determined to be legal and the file transmission is allowed.
Further, if the transmission request time information corresponding to the first signaling exceeds the timeout threshold, the signaling request may be regenerated, so as to generate a new signaling for the file transmission request.
Preferably, the method further comprises step S6 (not shown). In step S6, if the first signaling corresponds to a plurality of file transfer requests within the timeout threshold, the service device 1 provides a user with security prompt information.
Specifically, the service device 1 continuously interacts with the user device 2 to obtain a file transmission request sent by the user device 2; and if the first signaling corresponds to a plurality of file transmission requests within the overtime threshold, the file transmission corresponding to the file transmission position is considered to be risky, so that safety prompt information is provided for a user through the user equipment.
The safety prompting information includes but is not limited to text prompting, prompting of suggested operation and the like.
Preferably, the method further comprises step S7 (not shown). In step S7, if the first signaling corresponds to a plurality of file transfer requests within the timeout threshold, the user equipment 2 provides a security prompt to the user.

Preferably, when the file transfer request includes a file upload request, the method further includes step S8 (not shown); in step S8, the user device 2 caches the uploaded file as a first file.
Specifically, when the file transmission request includes a file upload request, the user equipment 2 caches the uploaded file as a first file, and the first file is associated with the file upload request. The first file may be a preview version of the uploaded file.
For example, if the file is a picture, the first file may be a thumbnail of the picture; if the file is a document, the first file can be a document abstract; if the file is a video, the first file can be a video clip or a video screenshot; if the file is audio, the first file may be a excerpted segment of the audio (e.g., audio of the previous few seconds).
More preferably, the method further includes step S9 (not shown), step S10 (not shown), step S11 (not shown); in step S9, the user equipment 2 generates a file viewing request according to the uploaded file corresponding to the file transmission location; in step S10, the user device 2 detects whether a first file is included in the user device, where the first file corresponds to the file viewing request; in step S11, if the user equipment includes the first file, the user equipment 2 displays the first file.
Specifically, in step S9, the user equipment 2 may generate a file viewing request for the uploaded file according to the uploaded file corresponding to the file transmission location, for example, the user may generate a file viewing request for the uploaded file by clicking a specific button at the file transmission location or sending a specific request.
Then, in step S10, the user equipment 2 detects whether the first file is stored in the user equipment, where the first file is an uploaded file cached in the user equipment.
If the user equipment includes the first file, in step S11, the user equipment 2 directly calls the first file in the user equipment and displays the first file to the user.
In other words, the user equipment no longer interacts with the service equipment, so that the uploaded file is prevented from being acquired in a network transmission mode, and the uploaded file is directly viewed in the user equipment.
It should be understood by those skilled in the art that, if the user equipment does not include the first file, the user equipment may interact with the service equipment again based on the method in the present invention to obtain the uploaded file sent by the service equipment (i.e., perform a file downloading operation).
Preferably, in step S3, the user equipment 2 may send an information transmission request to the service equipment 1, where the information transmission request includes a general data transmission request and a file transmission request, the file transmission request includes a file upload request and/or a file download request, and the file transmission request corresponds to the file transmission location; correspondingly, the service device 1 receives an information transmission request sent by the user device 2, wherein the information transmission request comprises a general data transmission request and a file transmission request, the file transmission request comprises a file uploading request and/or a file downloading request, and the file transmission request corresponds to the file transmission position; then, the method further includes step S12 (not shown), in step S12, the user equipment 2 transmits data corresponding to the general data transmission request to the service equipment 1; accordingly, the service device 1 receives the data corresponding to the general data transmission request, which is sent by the user device 2.
