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 embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.

The present disclosure first provides a file sharing method. The file sharing refers to a process of providing various file extraction entries to others through a network, and extracting files from the extraction entries by others. The format of the files herein may be arbitrary, including but not limited to text files, video files, image files, executable files, and the like. In a traditional mode, a file sharer directly provides a file extraction entry for a file demander in the file sharing process, and the mode has potential safety hazards for both the file sharer and the file demander, for example, a lawbreaker may pretend to share files which are not to be shared outwards by the file sharer, and the lawbreaker may pretend to be the file demander to acquire files which are not to be shared by the lawbreaker and the like.

The implementation terminal of the present disclosure may be any device having computing, processing, and communication functions, which may be connected to an external device for receiving or sending data, and specifically may be a portable mobile device, such as a smart phone, a tablet computer, a notebook computer, a pda (personal Digital assistant), or the like, or may be a fixed device, such as a computer device, a field terminal, a desktop computer, a server, a workstation, or the like, or may be a set of multiple devices, such as a physical infrastructure of cloud computing or a server cluster.

Optionally, the implementation terminal of the present disclosure may be a server or a physical infrastructure of cloud computing.

Fig. 1 is a schematic diagram of a system architecture of a file sharing method according to an exemplary embodiment. As shown in fig. 1, the system architecture includes a server 110 and a user terminal 120. The user terminal 120 is connected to the server 110 through a wired or wireless communication link, so that the user terminal 120 can transmit data to the server 110 and also can receive data from the server 110, and the server 110 is an implementation terminal in this embodiment. When the file sharing method provided by the present disclosure is applied to the system architecture shown in fig. 1, a specific process may be as follows: first, a target user registers an account on the server 110 through the user terminal 120 and via a communication link, and submits first login information and a first password in the form of a form; then, the server 110 will execute the step of generating a hash value based on the first login information, generate and store the first hash value; then, the target user may upload a file to the server 110 for storage by using the user terminal 120; when the target user wants to share the file stored in the server 110 to another person, the target user needs to submit the second login information to the server 110 through the user terminal 120 again; then, the server 110 generates a second hash value by using the second login information, and compares the second hash value with the first hash value; in the case that the second hash value is consistent with the first hash value, the server 110 will push a password authentication entry to the user terminal 120; the user terminal 120 submits the second password to the server 110 through the password authentication portal; finally, when the server 110 determines that the second password is consistent with the first password, a file sharing link is generated and pushed to the user terminal 120.

It is worth mentioning that fig. 1 is only one embodiment of the present disclosure. Although the embodiment of fig. 1 shows the implementation terminal as a server, in a specific application, the implementation terminal of the present disclosure may be various terminals or devices as described above; although in the above description of the specific process, the application scenario of the embodiment shown in fig. 1 is defined as a process of verifying the user identity to generate the file sharing link, in an actual scenario, the embodiment shown in fig. 1 may also be applied to a process of verifying the user identity before the user extracts the file. The embodiments of the present disclosure are not limited in this respect, and the scope of the present disclosure should not be limited thereby.

Fig. 2 is a flow diagram illustrating a file sharing method according to an example embodiment. This embodiment may be executed by a server, as shown in fig. 2, and includes the following steps:

step 210, obtaining first login information and a first password from a target user.

The first login information and the first password may be information generated at the time of user registration or provided by the user.

The first login information may include information such as a user name, a login password, a user IP address, etc., and the first password may be data of the same type as the login password, for example, the first password and the login password may both include english letters, numbers, characters, etc.

Step 220, executing the step of generating the hash value based on the first login information to obtain a first hash value.

Fig. 3 is a flowchart of the step of generating a hash value according to one embodiment shown in the embodiment of fig. 2. The specific steps related to the step of generating the hash value may be shown in fig. 3, please refer to fig. 3, where the step of generating the hash value specifically includes:

at step 310, form data corresponding to the login information is generated.

Each item of the form data comprises a data name and a parameter value corresponding to the data name.

The first login information and the first password can be submitted by a target user at a user side in a form mode, and form data can be correspondingly generated by the execution terminal of the disclosure after the first login information is submitted to the execution terminal of the disclosure.

For example, the first login information includes a user name of zhangsan, and the finally generated form data corresponding to the user name of zhangsan may be "username zhangsan".

And step 320, sorting the form data according to a preset rule based on the data name included in the form data.

In one embodiment, the sorting the items of form data according to a predetermined rule based on data names included in the items of form data includes:

and sequencing the form data according to the sequence of the characters in the data names in the preset word list.

In one embodiment, the specific steps of step 320 are shown in FIG. 4. Fig. 4 is a detailed flowchart of step 320 according to one embodiment shown in the fig. 3 embodiment. Referring to fig. 4, step 320 includes:

and 320', sorting the form data items from small to large according to the ASCII codes of the included data names.

In one embodiment, the sorting the items of form data from small to large according to the ASCII code of the included data name includes:

and selecting the form data with the minimum ASCII code of the first character of the included data name from each item of the form data, if the selected form data exceeds one, selecting the next character of the character on which the current form data is based as the first character, selecting the form data with the minimum ASCII code of the first character of the included data name from the selected form data again, and so on until one form data is selected, and using the form data as the form data with the minimum ASCII code of the first character of the included data name obtained by the selection at this time.

For example, there are four items of form data with data names u88ab, u78fd, u864a and v88ee, and first, since u ASCII code is smaller than v ASCII code, the first round selects the form data with the smallest ASCII code of the corresponding first character, and their corresponding data names u88ab, u78fd and u864 a; secondly, since the ASCII code of 7 is smaller than the ASCII code of 8, the data name corresponding to the form data with the smallest ASCII code of the first character selected in the second round is u78fd, and at this time, a form data, i.e., a form data with a data name of u78fd, is selected, and the form data is the form data obtained by this time selection.

dividing the characters into a plurality of priorities according to the size of the ASCII codes of the characters, so that the ASCII codes of the characters with smaller priorities are larger than the ASCII codes of the characters with larger priorities, and each priority corresponds to at least one character;

and sorting the form data of each item according to the priority of the first character of the included data name from large to small, and sorting the form data of each item with the first character of the included data name at the same priority according to the ASCII code of the included data name from large to small.

For example, if the first character of the data name included in the form data is a, b, c, d, e, f, if a and b are a priority, c and d are a priority, and e and f are a priority, then the priority of a and b is greater than that of c and d, and similarly, the priority of c and d is greater than that of e and f. If the form data is sorted in the manner of this embodiment, and if the form data is replaced with the first character of the data name included in the form data, after the form data is sorted from large to small according to the priority of the first character of the included data name, the sorting result may be a, b, c, d, e, f, and then after the form data of each item of the same priority is sorted from large to small according to the ASCII code of the included data name, the sorting result is b, a, d, c, f, e.

In this embodiment, the form data in which the first character of the included data name is ranked from large to small according to the priority of the first character of the included data name, and the form data in which the first character of the included data name is ranked at the same priority according to the ASCII code of the included data name, so that the ranking irregularity is increased, and the file sharing security is improved.

And 330, splicing the sorted form data and the additional character strings to obtain spliced form data.

In one embodiment, before the sorted form data is spliced with the additional character strings to obtain spliced form data, the method further includes:

randomly generating an additional character string;

the splicing the sorted form data and the additional character strings to obtain spliced form data comprises the following steps:

and splicing the last form data in the sorted form data with the additional character string to obtain spliced form data.

In this embodiment, the additional character string is spliced at the end of all the form data.

For example, if there are two items of form data, which are "three for username" and "123 for code", respectively, then the two items of form data may be "123 for code" and "three for username" after being sorted, and if the additional character string is abcde, then the form data obtained after being spliced may be:

code 123& username zhang triaabcde.

The additional character string may be generated randomly in various ways, such as directly randomly, or by randomly selecting a number of characters from a predetermined dictionary or character table.

randomly generating a corresponding additional character string for each item of the form data;

and splicing each item of form data with the corresponding additional character string to obtain spliced form data.

In this embodiment, an additional character string is spliced after each form data item, so that the security of file sharing is improved.

When form data is spliced with additional character strings, the additional character strings can be spliced at any other position besides after all the form data or after each character string, for example, the additional character strings can be spliced before all the form data, or one additional character string can be spliced every several form data.

And 340, performing hash operation on the spliced form data to obtain a hash value.

The hash operation may also be referred to as a digest operation, and the hash operation herein may be implemented based on various hash algorithms. Such as may be implemented based on the MD5 algorithm.

Next, continuing with fig. 2.

Step 230, obtaining second login information from the target user.

The second login information is information submitted when the target user needs to share the file or obtain the file shared by others. The second login information is different from the first login information in that the two are information submitted at different stages.

Step 240, executing the step of generating a hash value based on the second login information and the additional character string to obtain a second hash value.

This step will re-perform the hash value generation step between steps 310-340 based on the second login information and the additional string.

In one embodiment, the first login information includes a target account number, and before acquiring the second login information from the target user, the method further includes:

correspondingly storing the target account, the additional character string and the first hash value;

the acquiring of the second login information from the target user includes:

acquiring second login information, wherein the second login information comprises an account;

if the account number is consistent with the target account number, determining that the second login information comes from the target user;

the step of generating a hash value is performed based on the second login information and the additional character string to obtain a second hash value, and the step of generating a hash value includes:

determining an additional character string stored corresponding to the account;

and executing the step of generating the hash value based on the second login information and the determined additional character string to obtain a second hash value.

In this embodiment, effective verification of the user is achieved by finding the corresponding stored additional character string according to the account and obtaining the second hash value based on the found additional character string.

Of course, it is also possible to find the additional character string using another character string that can be used to identify the user information, such as the user name, and store the character string and the additional character string and store the correspondence between the character string and the additional character string.

And step 250, if the first hash value is consistent with the second hash value, pushing a password authentication entry to the terminal where the target user is located.

Password authentication portals may exist in various ways, such as pages, windows, and the like.

And step 260, acquiring a second password sent by the target user through the password authentication entrance.

For example, the target user may submit the second password in the form of a form entry box.

Step 270, if the second password is consistent with the first password, generating a file sharing link or providing an entry for extracting network file resources to the target user.

The file sharing link is a link generated for a user who wants to share the file outwards, and other people can extract network file resources by using the file sharing link; the entry for extracting the network file resource is established based on the file sharing link and can be used for directly extracting the network file resource, for example, the entry for extracting the network file resource may include a download button, and the network file resource can be downloaded by clicking the download button.

In one embodiment, the method further comprises:

and if the first hash value is inconsistent with the second hash value or the second password is inconsistent with the first password, returning prompting information representing that the identity is illegal.

In one embodiment, after obtaining the file to be shared uploaded by the target user, the method further includes:

storing the file to be shared to a preset file path and distributing a file identifier for the file to be shared;

if the second password is consistent with the first password, generating a file sharing link corresponding to the file to be shared, including:

and if the second password is consistent with the first password, generating a file sharing link corresponding to the file to be shared according to the preset file path and the file identification.

Specifically, the file sharing link may include a file identifier, a file path, and a corresponding relationship between the file identifier and the file path, where the file identifier may include a timestamp of a current time, a random number, and a letter with a predetermined length, the preset file path is a file address created for a corresponding file, and the corresponding relationship between the file identifier and the file path is a list index stored in a key value pair, for example: when the index of the file identifier is equal to 1, the index of the file path is equal to 1; when the index of the file identification is equal to 2, the index of the file path is equal to 2.

acquiring a file sharing link uploaded by the target user;

and if the second password is consistent with the first password, providing an entrance for extracting network file resources for the target user according to the file sharing link.

In this embodiment, the target user is a user who acquires the file resource by using the file sharing link, so that the user who wants to acquire the file resource is subjected to identity verification and password verification again under the condition that the identity verification is successful, and the user can acquire the file resource by using the file sharing link only under the condition that both the verification passes, so that the security of the user when acquiring the file resource provided by another person by using the file sharing link is improved.

In an embodiment, the file sharing link includes a first file identifier, a first file path, and correspondence information between the file identifier and the file path, and after the file sharing link uploaded by the target user is acquired, the method further includes:

A computer readable signal medium may include a propagated data signal with readable program code embodied therein, for example, in baseband or as part of a carrier wave. Such a propagated data signal may take many forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A readable signal medium may also be any readable medium that is not a readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a readable medium may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing. Program code for carrying out operations for aspects of the present invention may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, C + + or the like and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computing device, partly on the user's device, as a stand-alone software package, partly on the user's computing device and partly on a remote computing device, or entirely on the remote computing device or server. In the case of a remote computing device, the remote computing device may be connected to the user computing device through any kind of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or may be connected to an external computing device (e.g., through the internet using an internet service provider).
