Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a file transmission method.
Referring to fig. 1, fig. 1 is a flowchart illustrating a file transmission method according to a first embodiment of the present invention. In this embodiment, the file transfer method includes:
step S10, receiving a file to be transmitted sent by a sending terminal based on a special network, scanning the file to be transmitted, and comparing the file to be transmitted with a preset virus library to judge whether the file to be transmitted is a safe file;
in the file transmission of the embodiment, the private network is arranged between the financial institutions needing communication, and the transfer station is arranged on the private network, so that the access party of the private network only has two financial institutions needing communication, and other institutions cannot access the private network, thereby ensuring the security of the communication network. The transfer station transfers the files and data transmitted by communication, wherein a scanning mechanism is arranged, and only the scanned safe files and data can be transmitted to the financial institution through the transfer station. The financial institution which needs to transmit the file is used as a transmitting end, and the financial institution which receives the transmitted file is used as a receiving end. When the sending end transmits the file, the sending end can be triggered by requesting to send the file or can be directly sent. When the triggering mode of the request sending is used, a request instruction for file transmission is sent to the transfer station, the transfer station feeds back the request instruction, and when the feedback is that the sending end is determined to transmit the file, the file sending of the sending end is triggered, and the file to be sent is sent to the transfer station through a special network. When the file is sent directly, the file to be sent is sent to the transfer station directly through the private network without feedback determination of the transfer station. The transfer station receives the file sent by the sending end and takes the file as a file to be transmitted which needs to be transmitted to another financial institution.
In order to ensure the security of the received file to be transmitted, a preset virus library is set, wherein the preset virus library is a database which is preset and comprises a plurality of virus characteristic values, the virus characteristic values are characteristic values of viruses, and the characteristic values are serial number values of the determined viruses. For example, for identified viruses A, B and C, they are numbered 1, 2 and 3, and the numbers 1, 2 and 3 are used as the characteristic values of virus A, B, C, and are put into the database to form a preset virus library. After receiving a file to be transmitted sent by a sending end based on a private network, scanning the file to be transmitted based on a preset virus library, comparing the file to be transmitted with virus characteristic values in the preset virus library one by one, and determining whether the file to be transmitted carries any virus characteristic value so as to judge whether the file to be transmitted is a safe file.
Step S20, when the file to be transmitted is a safe file, sending prompt information to a receiving end;
when the file to be transmitted is determined to not carry any virus characteristic value in the preset virus library through scanning, the file to be transmitted is judged to be a safe file, and when the file to be transmitted can be transmitted to other financial institutions, prompt information is sent to the financial institutions needing to be transmitted, namely the receiving end, so as to prompt that the file to be transmitted needing to be sent to the receiving end exists. Specifically, the method comprises the following steps:
step S21, when the file to be transmitted is a safe file, storing the file to be transmitted and acquiring a receiving end identifier in the file to be transmitted;
when the file to be transmitted is a safe file without carrying the virus characteristic value, the safe file to be transmitted is stored, a file is generated for the file to be transmitted, and the uploading time, the file type, the file size and the like are recorded and archived. In addition, because each financial institution communicates with a plurality of other financial institutions, identifiers characterizing the source of the documents and the destination of the documents are added during document transmission in order to distinguish the communicating financial institutions. The identifier of the file source is the identifier of the sending end, and the identifier of the file destination is the identifier of the receiving end. And acquiring the receiving end identifier in the file to be transmitted so as to determine the receiving end of the file to be transmitted, which needs to be transmitted.
And step S22, determining the receiving end according to the receiving end identifier and sending the prompt information to the receiving end.
And further, determining a receiving end according to the obtained receiving end identifier in the file to be transmitted, and sending prompt information to the receiving end. The prompt information includes information such as the type, source and size of the file to be transmitted, so that the receiving end can judge whether the file to be transmitted needs to be acquired according to the prompt information. If the source of the file to be received and the financial institution without business are judged according to the prompt information, the file to be transmitted is not acquired; and if the content in the prompt message is the content required by the receiving end, acquiring the file to be transmitted.
And step S30, when a request instruction for acquiring the file to be transmitted is received, which is sent by the receiving terminal based on the prompt information, the file to be transmitted is sent to the receiving terminal based on the private network.
And when the receiving end judges that the file to be transmitted is the file meeting the requirement of the file to be transmitted according to the prompt information, sending a request instruction for acquiring the file to be transmitted so as to request to acquire the file to be transmitted. And in order to distinguish the request instruction from the request instructions of other receiving ends, a receiving end identifier for representing the uniqueness of the request instruction is added into the request instruction. And when a request instruction for acquiring the file to be transmitted, which is sent by the receiving terminal based on the prompt information, is received, acquiring a receiving terminal identifier carried in the request instruction. And comparing the receiving end identifier carried in the request instruction with the receiving end identifier in the file to be transmitted, and determining the receiving end of the file to be transmitted, which needs to be transmitted, when the identifiers of the receiving end identifier and the receiving end identifier are consistent. The file to be transmitted is also issued to the receiving end based on a special network, so that the security of the file to be transmitted is ensured while the transmitting end corresponds to the receiving end.
In the file transmission method of the embodiment, a file to be transmitted, which is sent by a sending end based on a private network, is received, the file to be transmitted is scanned, the scanned file is compared with a preset virus library, and whether the scanned file is a safe file is judged; when the file is a safe file, sending prompt information for prompting the receiving end to acquire the file to be transmitted; the receiving end sends a request instruction for acquiring the file to be transmitted based on the prompt information, and the file to be transmitted is sent to the receiving end based on a special network according to the request instruction. According to the scheme, the transmission of the transmission file is carried out through the special network, a scanning mechanism is set for the transmission file, and the transmission file is transmitted only when the transmission file is determined to be a safe file through scanning. The special network is only used for communication between financial institutions, and other institutions cannot access the special network, so that the safety of the communication network can be ensured; the scanning mechanism can ensure the security of the transmitted files, thereby improving the communication security between financial institutions.
Further, in another embodiment of the file transmission method of the present invention, when the file to be transmitted is a secure file, the step of sending the prompt message to the receiving end includes:
step S23, judging whether a plurality of files to be transmitted exist as security files, and when the plurality of files to be transmitted exist as security files, judging whether the plurality of files to be transmitted exist as security files with preset sending time marks or not;
understandably, different financial institutions have different transmission time requirements for transmitted files, the financial institutions have a plurality of users, a plurality of files related to the users may need to be transmitted during working hours in the daytime, and for some files unrelated to the users, the files are transmitted in non-working hours; or when the network load is detected to be small, the transmission is carried out; or the time transmission that the receiving end expects to receive the file to be transmitted by the transmitting end. And for the time when the sending end expects the receiving end to receive the file to be transmitted, the sending end adds a preset time identifier in the file to be transmitted so as to indicate the time for transmitting the file to be transmitted to the receiving end. And because each financial institution all docks a plurality of other financial institutions, when a plurality of financial institutions all need to carry out file transmission as the sending terminal, the file that awaits transmission that the transfer station received is a plurality of. Multiple files to be transmitted may cause transmission confusion if sent at the same time. Therefore, when the file to be transmitted is judged to be the safe file, whether a plurality of files to be transmitted which are the safe files exist is judged, and when the plurality of files to be transmitted which are the safe files exist, whether the files to be transmitted which carry the preset sending time identification indicating the transmission time exist in the plurality of files to be transmitted which are the safe files is judged.
Step S24, when a plurality of files to be transmitted are safe files, files to be transmitted carrying preset sending time marks are classified into a first type of files to be transmitted, and files to be transmitted not carrying the preset sending time marks are classified into a second type of files to be transmitted;
when a file to be transmitted, which carries a preset transmission time identifier, exists in a plurality of files to be transmitted, which are security files, it is stated that the transmission time of such a transmission file is determined by the preset transmission time identifier set by the transmitting end, for example, the content of the preset transmission time identifier is 27 pm 3 pm. The file to be transmitted is transmitted to the receiving end, so that the receiving end needs to send a request instruction first, namely, the file to be transmitted is transmitted to the receiving end only when the receiving end sends the request instruction first. The time transmission time of the file to be transmitted is determined by the receiving end, the preset sending time mark set by the sending end is used for appointing the time for sending the prompt information to the receiving end, and the receiving end sends the request instruction according to the prompt information, and the earliest time for obtaining the file to be transmitted is the time appointed by the preset sending time mark. And classifying the files to be transmitted carrying the preset sending time identification as a first class of files to be transmitted, and classifying the files to be transmitted not carrying the preset sending time identification as a second class of files to be transmitted. The time for sending the prompt information to the receiving end in the first type of file to be transmitted is determined by the preset sending time identifier, and the time for sending the prompt information to the receiving end in the second type of file to be transmitted can be real-time and can also be set according to the number of the files.
Step S25, sending prompt information to a receiving end corresponding to the first type of file to be transmitted according to the preset time identification carried in the first type of file to be transmitted;
and sending prompt information to a receiving end corresponding to the first type of files to be transmitted according to the preset time identification carried in each first type of file to be transmitted. And sending prompt information to a receiving end corresponding to the receiving end identifier when the time corresponding to the preset time identifier is reached according to the receiving end identifier.
And step S26, allocating time marks to the second type of files to be transmitted, and sending prompt information to a receiving end corresponding to the second type of files to be transmitted according to the allocated time marks.
And for the second class of files to be transmitted, distributing time marks to the second class of files to be transmitted, and sending prompt information to a receiving end corresponding to the second class of files to be transmitted according to the distributed time marks. When the time marks are distributed, the time marks distributed to different second-class files to be transmitted are different, so that different time points for sending prompt messages are represented. If there are A, B, C three files of the second type to be transmitted, time identifications of 2 pm, 3 pm and 4 pm can be respectively allocated to the files. The same second-class files to be transmitted carry receiving end identifiers representing the destinations of the second-class files, and if the receiving end identifiers corresponding to A, B, C are a, b and c respectively; thus, according to the receiving end identifier, when the time point of 2 pm is reached, the prompt message is sent to the receiving end identifier a; when the time point of 3 pm is reached, sending prompt information to a receiving end identifier b; when the time point of 4 pm is reached, a prompt message is sent to the receiving end identifier c. And sending prompt information to the receiving end through the distributed time identification, so that the sending time of the request instruction of the receiving end for requesting to acquire the file to be transmitted is different, and the second file to be transmitted is sent to the receiving end at different time points. In addition, in order to prevent the receiving end from not acquiring the file to be transmitted for a long time, the request time of the receiving end for requesting to acquire the file can be set, and the request instruction of requesting to acquire the file to be transmitted is effectively sent to the transfer station by the receiving end within the request time. And if the request time is longer than the preset time, the file is invalid so as to prevent the receiver from obtaining the file to be transmitted for a long time.
Further, in another embodiment of the file transmission method of the present invention, the step of sending the file to be transmitted to the receiving end based on the private network includes:
step S31, judging whether a plurality of files to be transmitted exist, and determining the file size of each file to be transmitted when the plurality of files to be transmitted exist;
when a request instruction for acquiring a file to be transmitted sent by a receiving end is received and the file to be transmitted is issued to the receiving end, because a plurality of files to be transmitted which need to be issued may exist, the transmission time of a plurality of files to be transmitted may overlap, and it appears that the transmission of one file to be transmitted is not completed, and another file to be transmitted is started to transmit, which results in the situation that the transmission of the previous file to be transmitted is slow or the transmission fails. Therefore, the implementation judges whether a plurality of files to be transmitted exist, when the files to be transmitted exist in a locked mode, the file size of each file to be transmitted is determined, and the file size represents the data volume to be transmitted.
And step S32, sequencing the files to be transmitted according to the file sizes of the files to be transmitted to generate a file sequence to be transmitted, and issuing the files to be transmitted to a receiving end based on a special network based on the sequence of the files to be transmitted.
Further, after the file size of each file to be transmitted is determined, the files to be transmitted are sequenced according to the sequence of the file sizes from small to large, and a file sequence to be transmitted is generated. If the file sizes of the files K1, K2 and K3 to be transmitted are 20K, 30M and 10M respectively, the file sequences to be transmitted are K1, K3 and K2. And according to the generated arrangement sequence of the file sequences to be transmitted, transmitting each file to be transmitted to a receiving end through a special network. According to the file size sequence from small to large, the transmission files are sent to the receiving end, after the transmission of the previous file to be transmitted with smaller data volume is completed, the transmission of the next file to be transmitted with larger data volume is carried out, and the problem that the transmission of other files to be transmitted is influenced because more time is consumed when the file to be transmitted with larger data volume is transmitted is avoided. Considering that a transfer station may have a large number of files to be transmitted, if the files to be transmitted with large data volume are arranged to be transmitted at last, the waiting time of the files to be transmitted with large data volume is too long, so that a priority mechanism is set. And setting a preset duration for judging the length of the waiting time, and judging that the waiting time of the file to be transmitted with large data volume is too long when the waiting time of the file to be transmitted with large data volume is longer than the preset duration, wherein the file to be transmitted is preferentially transmitted, and the waiting time is avoided from being too long.
Further, referring to fig. 2, a second embodiment of the file transmission method is proposed based on the first embodiment of the file transmission method of the present invention, and in the second embodiment, the step of sending the file to be transmitted to the receiving end based on the private network includes:
step S40, when it is detected that the file to be transmitted fails to be issued and a request instruction for acquiring the file to be transmitted again is received, the file to be transmitted is sent to the receiving end based on the private network.
Further, after the file to be transmitted is issued to the receiving end, an issue failure may occur, and when the issue failure occurs, the receiving end does not receive the file to be transmitted. Therefore, whether the file to be transmitted fails to be issued needs to be detected so as to ensure that the receiving end receives the file to be transmitted. The file to be transmitted is sent in a data packet mode, after the file to be transmitted is sent completely, the completion identifier is used as the last packet of data of the file to be sent to the receiving end, when the receiving end receives the completion identifier, the file to be transmitted is successfully issued, and when the completion identifier is still not received within a certain time, the file to be transmitted is failed to be issued. And when the transmission fails, generating a transmission failure identifier, returning the transmission failure identifier to the transfer station, and sending a request instruction for acquiring the file to be transmitted again. When the returned issuing failure identifier is detected, the issuing failure of the file to be transmitted is indicated, and whether a request instruction for acquiring the file to be transmitted again is received or not is judged. And when the file to be transmitted is detected to be failed to be issued and a request instruction for acquiring the file to be transmitted again sent by the receiving terminal is received, the file to be transmitted is sent to the receiving terminal again based on the special network. Correspondingly, when the sending end uploads the file to be transmitted to the transfer station, uploading failure can occur, when the file uploading failure is detected, a request is sent to the sending end again, and the sending end carries out the operation of uploading the file to be transmitted again according to the secondary sending instruction. The normal transmission of the file to be transmitted is ensured through the re-request and sending mechanism.
Further, referring to fig. 3, a third embodiment of the file transmission method of the present invention is provided on the basis of the first or second embodiment of the file transmission method of the present invention, and in the third embodiment, the file transmission method further includes the steps of:
and step S50, when the preset filing time is detected, filing the stored file to be transmitted, transferring and storing the file to be transmitted carrying the identifier with high importance degree, and deleting the file to be transmitted carrying the identifier with low importance degree.
Understandably, the transfer station can store and record the file to be transmitted, but the storage capacity is limited, and as the use time increases, the situation of insufficient capacity may occur, so that the transfer station needs to be archived. The preset filing time can be set according to the capacity of the transfer station and the data volume of the transmission file. When the preset filing time is detected, filing the stored files to be transmitted, transferring important files to be transmitted to storage equipment such as a hard disk, an optical disk and the like for storage, and deleting unimportant files to be transmitted; so as to store other files to be transmitted in the following. The importance and the non-importance of the file to be transmitted can be determined by the identifiers of the importance degree. When a transmitting end transmits a file to be transmitted, an identifier with high importance degree can be added to the important file to be transmitted; and a less important identifier is added to the less important file to be transmitted. And when filing, filing operation is carried out according to the important degree identifiers carried in the file to be transmitted. And if the file to be transmitted does not carry the identifier with the high or low importance degree during filing, the file to be transmitted is defaulted as the unimportant file to be transmitted, namely the file to be transmitted is used as the file to be transmitted carrying the identifier with the low importance degree, so that the deletion operation is carried out on the file.
