Detailed Description
In this embodiment, referring to fig. 1, the computer file network transmission method includes:
s1, acquiring characteristic information of a computer file;
s2, inquiring corresponding safety detection records of the characteristic information through the server;
s3, determining a transmission mode according to the safety detection record; the transmission mode is used for determining a calling mode of the anti-virus software and a sending state of the computer file from the client to the server;
s4, executing the determined transmission mode.
In this embodiment, steps S1-S4 may be applied in the computer network shown in FIG. 2. Referring to fig. 2, there are a server and n clients, and the clients may be terminals such as a desktop computer, a notebook computer, a tablet computer, or a mobile phone, and the clients and the server may be connected through media such as a network cable, a router, and an optical cable.
Steps S1-S4 may be performed when any client needs to upload a computer file to the server, and thus, one of the clients needs to upload a computer file to the server is described as an example.
In this embodiment, all of steps S1-S4 may be executed by the server, where the server may request the client to provide necessary support, for example, request the client to upload feature information when executing step S1; steps S1-S4 may also be performed by the client, where the client may request the server to provide the necessary support, for example, to query the security check record when performing step S2.
In this embodiment, the client that needs to upload the computer file installs the antivirus software, and the server side may or may not install the antivirus software.
In this embodiment, the client or the server may execute steps S1 to S4 by installing a security component on the client or the server.
Before executing steps S1-S4, it may be checked whether the client or the server has the security component installed, and if not, installation is prompted. The first time the security component is run, the running environment of the host is initially checked. Before executing steps S1-S4, it may be checked whether the client has authenticated anti-virus software installed, and if so, the real-time security detection function of the anti-virus software is enabled.
After confirming that the real-time security detection function of the antivirus software is normal, execution of steps S1-S4 may begin.
In step S1, the feature information may be information capable of describing the features of the computer file, such as file name, author signature, source, data size, generation time, etc., and these feature information may be directly obtained by searching for a specific data area in the computer file. The characteristic information may also be digest data obtained by processing the computer file by a digest algorithm, such as hash values. When executing step S1, the client transmits the feature information to the server either actively or at the request of the server.
In step S2, the server searches the security detection record in the database according to the feature information, and the searched result includes searching the corresponding security detection record (the security detection record exists) and not searching the corresponding security detection record (the security detection record does not exist). The server side searches the corresponding security detection record, which indicates that the computer file has been previously checked and killed by the antivirus software, and obtains the security detection record, wherein the specific content of the security detection record can pass (which indicates that the computer file has harmful contents such as computer viruses) or not pass (which indicates that the computer file does not have harmful contents such as computer viruses); the server cannot find the corresponding security detection record, which indicates that the computer file has not been previously checked and killed by the antivirus software, so that the corresponding security detection record is not generated.
In step S3, according to the specific situation of the security detection record, that is, the security detection record cannot be found, the found security detection record result is passed, the found security detection record result is failed, and the like, a calling mode of the antivirus software installed on the client and a sending state of the computer file from the client to the server are determined, in step S4, the determined transferring mode is executed, for example, the client calls or does not call the antivirus software to detect the computer file to be uploaded, the client directly sends the computer file to the server, and the client terminates sending the computer file to the server.
In the steps S1-S4, anti-virus software is installed on the client side, when the anti-virus software is required to be called for detection, the client side can directly sense the problems of the uploaded computer file and the information such as the uploading failure reason, and the user experience is improved; on the other hand, the client can directly call the anti-virus software installed on the client, so that the client can detect the computer file before or after encryption and more accurately judge the health of the computer file; and the transmission mode to be executed is determined according to the security detection record, so that the anti-virus software and the communication link resource from the client to the server are reasonably called, and the load condition of the computer network is improved.
In this embodiment, when step S3 is performed, that is, the step of determining the transmission mode according to the security detection record, the following steps may be specifically performed:
s301, when the security detection record is passed, the transmission mode is that the computer file is transmitted from the client to the server;
s302, when the security detection record is failed, the transmission mode is to terminate the transmission of the computer file;
s303, when the security detection record does not exist, the transmission mode is that anti-virus software is called at one side of the client side, the computer file is detected, the updated security detection record is obtained, when the updated security detection record is passed, the computer file is transmitted from the client side to the server side, and when the updated security detection record is not passed, the transmission of the computer file is terminated.
In step S301, if the server finds the security detection record and the result of the security detection record is a pass, it indicates that the computer file has been previously detected by the antivirus software, and the computer file is not found to include content such as computer virus, and the computer file is secure, and the transfer mode may be determined as "transfer computer file from client to server". When executing step S4, the client may not call the antivirus software to detect the computer file any more, and directly send the computer file to the server. Because the process of detecting the computer file again is omitted, resources of the client are saved, and the efficiency of transmitting the computer file is improved.
In step S302, if the server finds the security detection record and the result of the security detection record is failed, it indicates that the computer file has been previously detected by the antivirus software, and the computer file is found to contain content such as computer virus, and the computer file is dangerous, and the transmission mode may be determined as "terminate transmission of the computer file". When executing step S4, if the client does not start transmitting the computer file to the server, the client no longer transmits the computer file to the server; if the client has begun transmitting the computer file to the server, the client stops transmitting the computer file to the server. Because the process of re-detecting the computer file is omitted, the method is beneficial to saving the resources of the client and preventing the spread of computer viruses.
In step S303, if the server side cannot find the security detection record, the security detection record does not exist, the transmission mode may be determined as "call anti-virus software on the client side, detect the computer file, obtain an updated security detection record, and determine whether to transmit the computer file according to the result of updating the security detection record. When step S4 is performed, if the updated security detection record is passed, the client transmits the computer file to the server, and if the updated security detection record is failed, the client terminates the transmission of the computer file. By executing step S303, the client side may call the antivirus software to obtain the detection result of the computer file, that is, update the security detection record, so that the client side can directly perceive the problems existing in the uploaded computer file, and the information such as the cause of the uploading failure, thereby improving the user experience.
In this embodiment, when executing step S303, when the client invokes the antivirus software to detect the computer file, the client may temporarily not transmit the computer file to the server, and when the updated security detection record is obtained and passed, the client transmits the computer file to the server, thereby effectively guaranteeing the security of the computer. On the other hand, when executing step S303, the client may transmit the computer file to the server side at the same time when invoking the antivirus software to detect the computer file, that is, the two processes of "invoking the antivirus software to detect the computer file" and "transmitting the computer file to the server side" may be performed at the same time, thereby saving the time required for the computer file transmitting process.
Specifically, upon detecting the simultaneous transfer of a computer file from a client to a server, the client may perform the steps of:
s30101, decomposing the computer file to obtain a first part of file and a second part of file;
s30102, in the process of detecting the computer file, transmitting a first part of file from the client to the server;
s30103, if the detection of the computer file is completed before all the first part of files are transmitted to the server, and the obtained updated security detection record is passed, transmitting the first part of files and the second part of files from the client to the server;
s30104, if the detection of the computer file is completed before all the first part of files are transmitted to the server, and the obtained updated security detection record is failed, the transmission of the first part of files or the second part of files is terminated;
s30105, if the detection of the computer file is not completed after the first part of file is completely transmitted to the server, suspending the transmission of the second part of file, waiting for the detection of the computer file to be completed to obtain an updated security detection record, and executing the transmission of the second part of file according to the updated security detection record.
In step S30101, the client may copy the computer file to obtain a copy file identical to the computer file, decompose the copy file to obtain a first portion of file and a second portion of file, and simultaneously reserve the computer file. The first part of the file can be a part with larger data volume, the second part of the file can be a part with smaller data volume, the whole computer file is difficult to recover only by the first part of the file or the second part of the file, and the whole computer file can be recovered only by simultaneously obtaining the first part of the file and the second part of the file.
In step S30102, the client directly transmits the first portion of the file to the server during the process of detecting the computer file, that is, the two processes of "detecting the computer file" and "transmitting the first portion of the file from the client to the server" are performed synchronously.
If the "detect computer file" precedes "the transfer of the first partial file from the client to the server and the obtained updated security detection record is passed, i.e. the situation in step S30103, it indicates that the complete computer file is secure, and the client may transfer the first partial file and the second partial file to the server. Specifically, the client may send the first partial file to the server, and then send the second partial file to the server, where the server may obtain the first partial file and the second partial file, and recover to obtain the complete computer file according to the first partial file and the second partial file.
If the "detect computer file" precedes "the transfer of the first partial file from the client to the server and the obtained updated security detection record is not passed, i.e. the situation in step S30104, it indicates that the complete computer file is not secure, and the client may terminate the transfer of the first partial file or the second partial file. Specifically, if the client side has not completed the transmission of the first part of file, the transmission of the first part of file can be stopped, and the second part of file is not transmitted any more, and the server side can only obtain a part of data in the first part of file and can not obtain the second part of file, so that the complete dangerous computer file cannot be recovered, and the transmission of harmful data in the computer file is prevented.
If the "transfer of the first partial file from the client to the server" is finished before the "test the computer file", that is, the situation in step S30105 occurs, after the transfer of the first partial file is completed, the client temporarily does not start the transfer of the second partial file, waits for the completion of the test of the computer file to obtain an updated security detection record, and executes the transfer of the second partial file according to the updated security detection record. Specifically, if the updated security detection record passes, the client transmits the second partial file to the server, so that the server can obtain the second partial file, and recover to obtain the complete and safe computer file together with the first partial file which has been received before; if the updated security detection record is not passed, the client side does not transmit the second part of files to the server side, so that the server side cannot obtain the second part of files, the server side only obtains the first part of files, and cannot recover to obtain the complete dangerous computer files, and the transmission of harmful data in the computer files is prevented.
In this embodiment, when the security detection record does not exist, the client invokes the antivirus software to detect the computer file, and obtains the updated security detection record, and then the client obtains the current software version information of the antivirus software, where the current software version information includes information such as a system version, a virus library version, and the like, and transmits the information such as the feature information, the updated security detection record, and the current software version information to the server, and the server stores the information in the database, so that the computer file is marked as having undergone the detection of the computer file, and can be later invoked according to the index such as the feature information.
In this embodiment, when step S3 is performed, that is, the step of determining the transmission mode according to the security detection record, the following steps may be specifically performed:
s304, when a security detection record exists, historical software version information of antivirus software is obtained from the security detection record;
s305, acquiring the latest software version information of the antivirus software;
s306, determining performance difference information of the antivirus software according to the historical software version information and the latest software version information;
s307, detecting the performance difference information and the characteristic information;
s308, when the performance difference information is not matched with the characteristic information, the transmission mode is that the computer file is transmitted from the client side to the server side, otherwise, the transmission mode is that anti-virus software is called on one side of the client side, the computer file is detected, an updated security detection record is obtained, the computer file is transmitted from the client side to the server side when the updated security detection record is passed, and the transmission of the computer file is terminated when the updated security detection record is not passed.
In step S304, the client obtains the historical software version information of the antivirus software from the security detection record, where the historical software version information may be information recorded by the server, which reflects the information such as the system version, the virus library version, and the like of the antivirus software used when the computer file is previously detected by the antivirus software.
In step S305, in the case where the antivirus software has been updated to the latest version, the client may directly call the latest software version information from the update log of the antivirus software; in the case that the antivirus software is not updated to the latest version, the client may be networked with a vendor of the antivirus software to obtain the latest software version information of the antivirus software. The latest software version information comprises the latest system version, the latest virus library version and the like of the antivirus software.
In step S306, the client compares the historical software version information with the latest software version information to determine performance difference information of the antivirus software. The content of the performance difference information can be the newly added function of the latest version of antivirus software, including the newly added type of computer virus which can be defended or killed, the easily infected file characteristics of the novel computer virus, the common sources of the novel computer virus and the like.
In step S307, the client compares the performance difference information with the feature information, for example, determines whether the computer file conforms to the characteristics of the file that is susceptible to infection by the new computer virus, the common source of the new computer virus, and the like, and if the characteristics do not match, in step S308, the client may determine that the computer file is not infected by the new computer virus, and if the computer file has been previously detected by the antivirus software, and if the result is passed, the transfer mode is determined as "transfer the computer file from the client to the server", and when step S4 is executed, the client directly transfers the computer file to the server. If these characteristics do not match, which means that even though the computer file has been previously detected by the antivirus software, there is still a risk of infection with the new type of computer virus, in step S308, the transfer mode is "call antivirus software on the client side, the computer file is detected, an updated security detection record is obtained, when the updated security detection record is passed, the computer file is transferred from the client to the server, when the updated security detection record is failed, the transfer of the computer file is terminated, and when step S4 is executed, the client recalls the latest version of antivirus software to detect the computer file, an updated security detection record is obtained, and only if the updated security detection record is passed, the client transfers the computer file to the server, and when the updated security detection record is failed, the client does not transfer the computer file to the server.
By executing steps S304-S308, the latest version of the antivirus software can be tracked, and the computer file is again detected when appropriate, thereby reducing the risk of computer virus transmission.
The computer program for executing the computer file network transmission method in the present embodiment may be written in a computer device or a storage medium, and when the computer program is read out to run, the computer file network transmission method in the present embodiment is executed, thereby achieving the same technical effects as the computer file network transmission method in the embodiment.
