Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

However, if the user encrypts the file manually after downloading the file, the workload of the user is large, the user is easy to forget, the efficiency of downloading the file is low, the user can only encrypt the downloaded file, the file in the downloading process cannot be encrypted or hidden, the file is likely to be peeped by others in the downloading process, and the privacy of the user is threatened.

The method includes the steps that whether preset characteristics matched with the privacy files are included in the downloading characteristics is determined by obtaining the downloading characteristics of the files to be downloaded, and when the preset characteristics are included in the downloading characteristics, the files to be downloaded are downloaded into the privacy space, wherein the privacy space is used for storing the privacy files. Through discernment treat the download characteristic of download file, and whether including the predetermined characteristic in the detection download characteristic, thereby can follow the root and directly judge whether should treat the download file is the privacy file, whether need carry out encryption processing, thereby the efficiency of encryption has been promoted, and when including the predetermined characteristic in the download characteristic, can directly download the file of treating to the privacy space in, thereby accomplish to treat that the whole download process of download file carries out privacy encryption, prevent to treat that the file of downloading is stolen secretly by other people in the download process, the security of file download has been promoted.

FIG. 1 is a flowchart illustrating a file download method according to an exemplary embodiment, and as shown in FIG. 1, the method includes the following steps S101-S103:

in step S101, a download feature corresponding to a file to be downloaded is obtained.

In step S102, it is determined whether the download features include preset features that match the privacy file.

In step S103, when it is determined that the download features include the preset features, the file to be downloaded is downloaded to a privacy space, where the privacy space is a space for storing the privacy file.

Illustratively, a privacy space is a space with permission verification or with hidden attributes, where files placed in the privacy space are not visible to users without permission. The privacy space may be a folder manually set by the user himself or may be a folder established or defaulted by the downloader. And the permission verification mode of the privacy space can include but is not limited to at least one of the following encryption modes: digital encryption, symbol encryption, text encryption, letter encryption, graphic encryption, fingerprint encryption, and the like; or the privacy space may also be provided in the form of a hidden folder.

In order to prevent the file from being peeped by others in the downloading process, the privacy of the user is threatened. Therefore, the file to be downloaded needs to be protected in the downloading process of the file to be downloaded. When the file to be downloaded needs to be protected in the downloading process, the downloading characteristics of the file to be downloaded need to be judged, and when the corresponding file to be downloaded is judged to be the file needing to be protected from the downloading characteristics, the file to be downloaded can be protected in the downloading process.

According to the method and the device, after the downloading characteristics of the file to be downloaded are obtained, whether the downloading characteristics comprise the preset characteristics matched with the privacy file or not is determined, when the downloading characteristics comprise the preset characteristics, the corresponding file to be downloaded is determined to be protected in the downloading process, the file to be downloaded is directly downloaded into the privacy space, whether the downloading characteristics corresponding to the downloading file comprise the preset characteristics matched with the privacy file or not can be detected, whether the file to be downloaded is stored into the privacy space or not is determined, a user does not need to judge whether the file to be downloaded is stored into the privacy space or not, the file downloading efficiency is effectively improved, and user experience is improved.

Because the privacy space is a space with authority verification or hidden attributes, the privacy space is generally protected, meanwhile, a transmission channel between the privacy space and the downloading source is also protected, and an ordinary person cannot peep the file transmitted in the transmission channel, when the downloading characteristics corresponding to the file to be downloaded include the preset characteristics matched with the privacy file, namely, the file to be downloaded is determined to be downloaded into the privacy space, the file to be downloaded can be transmitted through the transmission channel established between the downloading characteristics and the privacy space, the file to be downloaded is protected in the downloading process, and the downloading safety is effectively improved.

And because the file to be downloaded is finally downloaded into the privacy space, and the privacy space is a protected folder, the storage and the lookup of the downloaded file to be downloaded are correspondingly protected, and the file to be downloaded does not need to be manually encrypted after the downloading of the file to be downloaded is completed, so that the encryption efficiency and the downloading efficiency are effectively improved.

The embodiment of the disclosure provides a file downloading method, which includes: the method comprises the steps of obtaining downloading characteristics corresponding to a file to be downloaded, determining whether the downloading characteristics comprise preset characteristics matched with a privacy file, and downloading the file to be downloaded to a privacy space when the downloading characteristics comprise the preset characteristics, wherein the privacy space is a space for storing the privacy file. Whether the file to be downloaded needs to be downloaded to the privacy space is determined through the downloading characteristics corresponding to the file to be downloaded, the file downloading efficiency is effectively improved, and the user experience is improved.

In an embodiment, the download feature corresponding to the file to be downloaded may be a Uniform Resource Locator (URL) corresponding to the file to be downloaded.

In this case, as shown in fig. 2, the step S101 may be implemented as step S1011, the step S102 may be implemented as step S1021, and the step S103 may be implemented as step S1031:

in step S1011, a uniform resource locator URL corresponding to the file to be downloaded is obtained.

In an implementation mode, when a user needs to download a file, the user can directly input a URL corresponding to the file to be downloaded in a download task box of the downloader, and at this time, the URL can be directly acquired.

In another implementation manner, a user may determine a downloaded file by clicking, since the file to be downloaded corresponds to a URL in the server, the clicking operation may be used as a trigger condition for acquiring the URL, and after the user clicks the file to be downloaded, the URL is directly sent to the downloader. The server is used for generating, storing and pushing a white list containing preset characteristics.

For example: as shown in the mobile phone interface of fig. 3, when a user wants to download a movie, movie 1, movie 2, movie 3, movie 4, movie 5, and movie 6 are displayed in the movie library, and when the user wants to download movie 3, the user clicks the icon of movie 3, and when the user clicks the icon of movie 3, the URL corresponding to movie 3 is sent to the downloader.

In step S1021, it is determined whether a preset key character matching the privacy file is included in the URL.

In step S1031, when it is determined that the URL includes the preset key character matching the privacy file, the file to be downloaded is downloaded to the privacy space.

The key characters include, but are not limited to, the following three types:

the first method comprises the following steps: the key character may also be a complete URL.

And the second method comprises the following steps: the URL will carry a hash value, for example: the URL may be: com/? The "a # hash" is a hash value of the URL, and in this case, the hash value of the URL may be used as the key character.

And the third is that: the URL will carry a string consisting of%, #, &, letters, numbers, etc., for example: in http:// www.example.com/indexname ═ na% 26 me% 3d1& id ═ id2, "indexname ═ na% 26 me% 3d1& id ═ id 2", the above character string in the URL can be used as the above key character.

In one embodiment, the preset keyword may be directly obtained locally by the client of the downloader in the present disclosure.

And when a plurality of historical downloading URLs are obtained, the historical downloading URLs are URLs corresponding to files which are placed into the privacy space by a user after downloading is completed in the historical downloading tasks, and then preset key characters are obtained according to the plurality of historical downloading URLs.

And after the preset key character is obtained, the preset key character can be uploaded to a server.

In another embodiment, the preset key character may also be acquired by the server. At the moment, a plurality of historical download URLs are obtained, wherein the historical download URLs are URLs corresponding to files which are placed into a privacy space by a user after downloading is completed in a historical download task, and then the historical download URLs are uploaded to a server so that the server can obtain preset key characters according to the historical download URLs. And after the server acquires the preset key characters, pushing the preset key characters to the terminal equipment, so that the terminal equipment locally determines whether the file to be downloaded needs to be downloaded into the privacy space after acquiring the URL corresponding to the file to be downloaded. Certainly, the server may not push the preset key characters obtained by the server to the terminal device, and then, after the terminal device obtains the download features corresponding to the file to be downloaded, the download features may be uploaded to the server, so that the server performs the step of judging whether the file to be downloaded needs to be downloaded into the privacy space, and when the server determines that the file to be downloaded needs to be downloaded into the privacy space, a response message is sent to the terminal device, where the response message is used to instruct a downloader in the terminal device to download the file to be downloaded into the privacy space. Certainly, after the server obtains the preset key characters, a white list can be generated according to the preset key characters, and the white list is pushed to the client side and serves as a judgment basis.

In the above implementation manner, the plurality of historical download URLs are obtained, which may be obtained by a downloader actively detecting a download task of a user, or may be actively uploaded by the user.

The above-mentioned obtaining of the preset key character according to the plurality of historical download URLs may be implemented by the following several ways:

a first implementation manner for obtaining the preset key characters according to the plurality of historical download URLs is as follows: and acquiring the URL with the occurrence frequency exceeding a third preset threshold in the historical downloading URL in the privacy space as the preset key character.

For example: the third preset threshold is 2, and when the obtained historical download URL is: 111.222.333.444/521, 111.223.333.444/521, 111.222.333.444/521, 111.224.333.444/521 and 111.222.333.444/521, wherein the number of times 111.222.333.444/521 appears is 3, and the number exceeds a third preset threshold value 2, and then the 111.222.333.444/521 is determined to be a preset key character.

At this time, after the URL corresponding to the file to be downloaded is acquired, whether the key character identical to the URL exists in the plurality of preset key characters is directly determined, and when the key character identical to the URL exists in the plurality of preset key characters, the file to be downloaded is determined to be the file which needs to be stored in the privacy space.

The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: the preset key characters are obtained according to the complete historical download URL, so that the coverage range of the preset key characters is small, and the accuracy of judging whether the file to be downloaded needs to be stored in the privacy space is higher.

Since matching through a complete URL makes the matching granularity too large and the matching too coarse, the matching result is not accurate enough, so that some of the files that should be saved in the privacy space are ignored.

Taking the net disk as an example: the preset key character is "pan.baidu.com/xxx", and the URL corresponding to the file to be downloaded is "pan.baidu.com/x 11", and since the two URLs are different, it is determined that "pan.baidu.com/x 11" is not the file to be saved in the privacy space. And "pan.baidu.com/x 11" is actually a file that the user wishes to save to the private space.

A second way to obtain the preset key characters according to the plurality of historical download URLs can be implemented as follows: the step of obtaining preset key characters according to the plurality of historical download URLs comprises the following steps: segmenting each historical download URL to obtain a plurality of segmentation words; acquiring segmentation words of which the occurrence times exceed a fourth preset threshold value from the plurality of segmentation words; and taking the segmentation words exceeding a fourth preset threshold value as preset key characters.

After obtaining a plurality of historical download URLs, segmenting each historical download URL according to a preset rule to obtain a plurality of segmentation words, wherein the preset rule can be input by a user and can also be built in a downloader, and the method does not limit the acquisition mode of the preset rule. The preset rule can be used for segmenting a group of two words, a group of three words or the user, and the segmentation mode indicated in the preset rule is not limited by the disclosure.

For example: the fourth preset threshold is 2, and the following three historical download URLs are obtained: pan.baidu.com/xxx, pan.baidu.com/x11, pan.baidu.com/x12, segmenting the historical download URLs according to punctuation, the segmentations obtained by pan.baidu.com/xxx are: { pan, baidu, com, xxx }; com/x11 the resulting segmentations were: { pan, baidu, com, x11 }; com/x12 the resulting segmentations were: { pan, baidu, com, x12}, based on the above groups of segregants, judging that the number of occurrences of the segregant pan is 3, the number of occurrences of baidu is 3, the number of occurrences of com is 3, the number of occurrences of xxx is 1, the number of occurrences of x11 is 1, and the number of occurrences of x12 is 1; at this time, pan, baidu, and com may be used as the preset key characters.

At this time, when it is detected that the number of the preset key characters included in the URL corresponding to the file to be downloaded is greater than or equal to a fifth preset threshold, the file to be downloaded is downloaded to the privacy space.

For example: the fifth preset threshold is 3, the preset key characters are 111, 333 and 444, and when the obtained URL corresponding to the file to be downloaded is: 111.222.333.444/521, at this time, by detecting that the preset key characters included in the URL are 3 in total, it is determined that the file to be downloaded corresponding to the URL needs to be saved in the privacy space at this time.

For another example: the fifth preset threshold is 3, the preset key characters are 111, 333 and 444, and when the obtained URL corresponding to the file to be downloaded is: 111.222.111.444/521, at this time, by detecting that the preset key characters included in the URL are 3 in total, 111, and 444, it is also determined that the file to be downloaded corresponding to the URL needs to be saved in the privacy space at this time.

For example, the URL corresponding to the file to be downloaded may be scored, and when the score is greater than a preset score value, it is determined that the file to be downloaded corresponding to the URL needs to be stored in the privacy space.

The scoring criteria at this point may be: when the URL corresponding to the file to be downloaded comprises one preset key character, the score is 1, when the URL corresponding to the file to be downloaded comprises two preset key characters, the score is 2, and the rest is repeated, and when the score is larger than or equal to 3, the file to be downloaded corresponding to the URL is determined to be stored in the privacy space.

For example: presetting key characters as 111, 333 and 444, and when the obtained URL corresponding to the file to be downloaded is: 111.222.111.444/521, at this time, by detecting that the preset key characters included in the URL are 3 in total, the score of the URL is 3 at this time, it is determined that the file to be downloaded corresponding to the URL needs to be saved in the privacy space.

The scoring criteria at this time may also be: when the URL corresponding to the file to be downloaded comprises one preset key character, the score is 1, when the URL corresponding to the file to be downloaded comprises two preset key characters, the score is 2, and the rest is repeated, and when the score is greater than or equal to 2, the file to be downloaded corresponding to the URL is determined to be stored in the privacy space.

For example: presetting key characters as 111, 333 and 444, and when the obtained URL corresponding to the file to be downloaded is: 111.222.111.444/521, at this time, by detecting that the preset key characters included in the URL are 2 types in total, the score of the URL is 2, and it is determined that the file to be downloaded corresponding to the URL needs to be saved in the privacy space.

As can be seen from the above analysis, the "com" is a second-level domain name for the industrial and commercial financial enterprise, and therefore, the "com" is included in the URL address of the industrial and commercial financial enterprise, and therefore, it is not accurate enough to use the "com" alone as the preset key character. Therefore, a word composed of the first segmentation word exceeding a fourth preset threshold and the second segmentation word exceeding the fourth preset threshold can be used as a preset key character, wherein the first segmentation word and the second segmentation word belong to the same history download URL, and the first segmentation word and the second segmentation word belong to an adjacent relation.

Continuing with the above example, when a disjunct is obtained that exceeds a second preset threshold: after pan, baidu and com, judge pan and baidu first, because pan and baidu belong to the same historical download URL "pan.

Since the URL includes the directory names of the respective levels, taking pan.baidu.com/xxx as an example, the website root directory obtained after splitting according to the directory names is pan.baidu.com, and the next-level directory of the acquired website root directory is xxx. Thus. In another implementation manner, after obtaining a plurality of historical download URLs, each historical download URL is segmented according to a directory name to obtain a plurality of directory names, and then preset key characters are obtained according to the directory names.

As shown in fig. 4, a third implementation manner for obtaining the preset keyword according to the plurality of historical download URLs includes the following steps: in step S201: and performing directory segmentation on each historical download URL to obtain a plurality of directory names.

In step S202: and acquiring the directory names of which the occurrence times are greater than or equal to a first preset threshold value in the plurality of directory names.

In step S203: and taking the directory name with the occurrence frequency larger than or equal to a first preset threshold value as a preset key character.

For example: the first preset threshold is 2, and the following three URLs under history are obtained: pan.baidu.com/xxx, pan.baidu.com/x11, pan.baidu.com/x12, segmenting the historical download URL according to the directory name to obtain a plurality of directory names, and then segmenting pan.baidu.com/xxx according to the directory to obtain a plurality of directory names: { pan.baidu.com, xxx }; the names of a plurality of directories obtained by splitting pan.baidu.com/x11 according to the directories are as follows: com, x11 }; the names of a plurality of directories obtained by splitting pan.baidu.com/x12 according to the directories are as follows: { pan.baidu.com, x12}, based on the above-mentioned each group of directory names, it was judged that the number of occurrences of the directory name pan.baidu.com was 3, the number of occurrences of xxx was 1, the number of occurrences of x11 was 1, and the number of occurrences of x12 was 1; com is greater than a first preset threshold, and thus, is used as a preset key character.

A fourth achievable way of obtaining the preset key characters according to the plurality of historical download URLs is as follows: after the completion of the file downloading of the user is monitored, the user has the action of actively placing the downloaded file into the privacy space, which indicates that the downloaded file is most likely to be a URL related to privacy. Then, these collected URLs can be passed through and uploaded to the server. The server collects the URLs acquired by a plurality of users and judges whether the URLs are preset key characters.

For example: if more than 50% of users choose to put the file downloaded to the same URL into the privacy space, the URL is determined to be the preset key character.

At this time, a white list may be further preset in the server, and the preset key character is stored in the white list, so that after the server obtains the preset key character, the preset key character is added to the white list.

Because the client uploads the historical download URL to the server periodically or in real time, the server needs to update the white list according to the preset key characters determined in the later period, so that the coverage range of the white list is wider.

Since the white list is updated, the server needs to push the updated white list to the client in a certain period or in real time.

It should be noted that the step of determining whether to download the file to be downloaded into the privacy space may also be performed by a machine learning method in combination with the historical download URL and the URL corresponding to the file to be downloaded.

In another embodiment, the download feature corresponding to the file to be downloaded may be a file feature in a seed file corresponding to the file to be downloaded.

In this case, as shown in fig. 5, the step S101 may be implemented as the step S1012, the step S102 may be implemented as the step S1022, and the step S103 may be implemented as the step S1032:

in step S1012, file characteristics in a seed file corresponding to the file to be downloaded are obtained, where the file characteristics in the seed file include: file feature values recorded in the seed file.

In step S1022, it is determined whether the feature value in the seed file is the same as the preset feature value matched with the privacy file.

In step S1032, when it is determined that the feature value in the seed file is the same as the preset feature value matched with the privacy file, the file to be downloaded is downloaded to the privacy space.

When a user downloads a file, the file may be downloaded not only through the URL described above but also through a Bitstream (BT) seed.

For the seed file, the seed file itself is a text-like file. The file itself records the file characteristic value (e.g., digital digest value) of the file to be downloaded, and at this time, it can be determined whether the file to be downloaded needs to be downloaded into the privacy space according to the file characteristic value.

At this time, obtaining the preset feature value may be achieved by the following several ways:

1) after the file characteristic values of the plurality of historical seed files are obtained, the client side obtains preset characteristic values according to the file characteristic values of the plurality of historical seed files, and the client side locally stores the preset characteristic values.

At this time, when the file characteristics in the seed file corresponding to the file to be downloaded are obtained, the client may directly execute the above step of determining whether to download the file to be downloaded into the privacy space according to the preset characteristic value.

2) After the file characteristic values of the plurality of historical seed files are obtained, the client side obtains preset characteristic values according to the file characteristic values of the plurality of historical seed files, and the client side uploads the preset characteristic values to the server.

At this time, when the file characteristics in the seed file corresponding to the file to be downloaded are obtained, the client sends the file characteristics in the sub file to the server, so that the server executes the step of determining whether to download the file to be downloaded into the privacy space according to the preset characteristic value.

3) After the file characteristic values of the plurality of historical seed files are obtained, the client sends the file characteristic values of the historical seed files to the server, so that the server obtains preset characteristic values according to the file characteristic values of the plurality of historical seed files and locally stores the preset characteristic values.

4) After the file characteristic values of the plurality of historical seed files are obtained, the client sends the file characteristic values of the historical seed files to the server, so that the server obtains preset characteristic values according to the file characteristic values of the plurality of historical seed files, and the server pushes the preset characteristic values to the client.

An example method for acquiring the preset feature value includes: after a user downloads a certain file through the seed file, if the user puts the downloaded file into the privacy space after the downloading is completed, the client reads the file characteristic value of the downloaded file from the seed file and reports the file characteristic value to the server. The server collects the information uploaded by a plurality of users, and if the users with the same file characteristic value are found to be put into the privacy space by more than a certain proportion of users, the file corresponding to the file characteristic value can be determined as the privacy file. This file characteristic value may be taken as a preset characteristic value.

At this time, the server may further preset a white list, and the white list stores the preset feature value, so that after the server obtains the preset feature value, the preset feature value is added to the white list.

The client uploads the file characteristic value of the history seed file to the server periodically or in real time, so that the server needs to update the white list according to the preset characteristic value determined in the later period, and the coverage range of the white list is larger.

The example method of obtaining the preset feature value may further include: after a user downloads a certain file through a seed file, if the user puts the downloaded file into a privacy space after the downloading is completed, the client reads the file characteristic value of the downloaded file from the seed file, collects the information uploaded by a plurality of users, and if the user who exceeds a certain proportion puts the file with the same file characteristic value into the privacy space, the file corresponding to the file characteristic value can be determined to be the privacy file. The client may take this file characteristic value as a preset characteristic value. And then, the client can upload the preset characteristic values to the server so as to store the preset characteristic values by the server.

It is worth noting that whether the file to be downloaded needs to be downloaded into the privacy space can be determined by combining the file characteristic values of the plurality of historical seed files and the file characteristics in the seed file corresponding to the file to be downloaded, through a machine learning method.

The method for acquiring the file characteristics in the seed file corresponding to the file to be downloaded comprises the following steps: the file characteristics in the seed file are obtained through a Message Digest Algorithm fifth edition (MD 5 for short) 5, a hash Algorithm or a secure hash Algorithm.
