Detailed Description

The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.

The terms "first," "second," and the like in the description of the present application, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or otherwise described herein, and that the objects identified by "first," "second," etc. are generally of a type not limited to the number of objects, for example, the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The file sharing method and the electronic device provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.

In some embodiments of the present application, a file sharing method is provided, which is executed by a first electronic device, and fig. 1 shows one of flowcharts of the file sharing method in some embodiments of the present application, and as shown in fig. 1, the file sharing method includes:

step 102, a first input to a first file is received.

In the embodiment of the application, the first file can be a picture, or can be a file such as video, audio, text or document. The first input is specifically an input to share the first file, such as by social software sending the first file to the target user or sending the first file to the target chat group.

Step 104, in response to the first input, encrypting the first file to obtain an encrypted second file, and sharing the second file to the first object.

The display parameters of the second file in the second electronic device corresponding to the first object have an association relationship with at least one of the following: the display position of the second file and the decryption result of the second file; at least a portion of the content of the second file is different from at least a portion of the content of the first file.

In the embodiment of the application, after receiving the first input of sharing the first file by the user, the first file is encrypted. The user can set whether the sharing operation is encrypted or not by himself. For example, when the user shares the first file, a prompt window for asking the user whether to encrypt may be popped up, and whether to encrypt the first file may be determined according to the selection result of the user.

After the first file is encrypted, an encrypted second file is obtained, and at least part of the content of the second file is different from at least part of the content of the first file.

Illustratively, the content of the second file is completely different from the content of the first file.

Illustratively, a portion of the contents of the second file is the same as a portion of the contents of the first file, and another portion of the contents of the second file is different from all of the contents of the first file. Since the content of the second file is not identical to the first file, the real privacy information of the user can be hidden.

And after the second file is obtained, sharing the second file to the first object according to the first object designated by the user. The display mode of the second file on the second electronic device of the first object may be different according to the display position of the second file and the decryption result of decrypting the second file.

The display parameters of the second file determine a display mode of the second file, such as displaying the second file hiding the real content or displaying the original first file.

The display position of the second file is specifically an application program or a window in the application program for displaying the second file, such as displaying the second file in a web browser, displaying the second file in a private chat window of the chat software or displaying the second file in a group chat window of the chat software.

For example, the user may specify that the actual content of the first file is to be displayed only when the display location of the second file is a chat window with the first object, and otherwise the second file is to be displayed with the actual content hidden.

If the display position of the second file is not the display position designated by the sharer or the second object is decrypted and fails, other content different from the real content of the first file is displayed, so that only the object which the user wants to share can see the real content of the first file.

For example, fig. 2A, fig. 2B, fig. 2C, fig. 2D, fig. 2E, fig. 2F, fig. 2G, and fig. 2H respectively show interface schematic diagrams of a file sharing method according to an embodiment of the present application, as shown in fig. 2A, a chat window 200 includes a user a and a user B, where the user a is a first object, and the user B is a second object.

As shown in fig. 2B, if user B wishes to share the first file 202 with user a, a first input may be made to the first file 202.

As shown in fig. 2C, after receiving the first input of user B, a window 204 is displayed asking user B whether to encrypt the first file 202.

As shown in fig. 2D, when the user selects encryption, the first file 202 is encrypted, and at this time, an encrypted second file 206 is obtained, and the content of the second file 206 is different from the content of the first file 202.

As shown in fig. 2E, after obtaining the second file 206, the user B sends the second file 206 into the chat window 200. The screen seen by user B at this time is shown in fig. 2E, and the screen seen by user a is shown in fig. 2F.

As shown in fig. 2G, after the user a receives the second file 206, since the display position of the second file 206 is the chat window 200 specified by the user B, and the sharing object that receives the second file 206 is the user a specified by the user B, the user a can see the window 208 at this time, and the window 208 prompts the user a whether to decrypt the second file 206.

After the user a selects to decrypt the second file 206 and the decryption is successful, the picture seen by the user a is shown in fig. 2H, and at this time, the user a can see the first file 202 actually shared by the user B in the chat window.

According to the embodiment of the application, the files possibly containing the user privacy can be distinguished and displayed according to different display positions of the files and different decryption results of the files, so that only the objects which the user wants to share can see the real content of the shared files, therefore, the user privacy information can be effectively prevented from being seen by irrelevant people, the user privacy can be prevented from being spread in irrelevant channels, the user privacy is effectively protected, and the privacy leakage is prevented.

In some embodiments of the present application, encrypting the first file includes:

acquiring a third file and an encryption suite;

and encrypting the first file through the third file and the encryption suite to obtain a second file, wherein the content of the second file comprises at least part of the content of the third file.

In the embodiment of the application, when the first file is encrypted, the first file can be encrypted through a preset encryption suite and a third file in a file library associated with the encryption suite.

Specifically, after the first file is encrypted by the encryption suite and the third file, the content of the first file can be hidden, and the second file can be obtained. The content of the second file may be determined according to the third file, or may be randomly generated in combination with the partial content of the first file and the partial content of the third file.

The first file and the third file are each a picture file, and after the first file is encrypted by the encryption suite and the third file, the content of the second file obtained is the same as the third file and different from the first file.

The first file and the third file are each a picture file, and after the first file is encrypted by the encryption suite and the third file, the image content of the background area of the obtained second file is the same as that of the first file, and the image content of the main area of the second file is the same as that of the third file.

For example, the first file is a photograph of person a standing in front of the door, the third file is a photograph of person B standing in front of the window, and the second photograph generated is a photograph of person B standing in front of the door.

According to the embodiment of the application, the random third file is used as the reference file, the first file is encrypted through the encryption suite and the third file, and the real content of the first file possibly containing the privacy of the user is covered through the content of the irrelevant third file, so that the interest and curiosity of the third party user can not be caused when the encrypted file is shared, the privacy sharing behavior of the user is further hidden on the basis of protecting the privacy of the user, and the privacy protection reliability and privacy protection effect are improved.

In some embodiments of the present application, the encryption suite is a first encryption suite, and the encrypting the first file by using the third file and the encryption suite to obtain a second file includes:

receiving a second input;

and responding to the second input, and carrying out confusion encryption on the first file by taking the object information and the first position information of the first object as confusion parameters through the first encryption suite and the third file to obtain a second file, wherein the second file comprises a decryption suite corresponding to the first encryption suite, and a decryption key of the second file is determined according to the object information and the first sharing path of the first object.

In the embodiment of the application, the first encryption suite is specifically a system-level encryption suite, the files encrypted by the system-level encryption suite can be shared through a plurality of different sharing ways, and the shared objects of the files encrypted by the system-level encryption suite are received, so that the encrypted files can be subjected to decryption processing in response to the corresponding system-level decryption suite.

Specifically, when the first file is encrypted by the system-level encryption suite, that is, the first encryption suite, the user inputs object information and first location information of the first object.

The first encryption suite uses object information and first position information of a first object as confusion parameters, carries out confusion encryption processing on a first file according to a third file, and obtains a second file after processing, wherein the second file is a sharing suite file, and the sharing suite file comprises a decryption suite corresponding to the first encryption suite.

When the sharing object receives the second file, the sharing suite judges whether the object is an object specified by object information of the first object, judges whether the display position of the second file is a display position indicated by the first position information, if so, determines a decryption key based on the object information of the first object and the first position information through a decryption suite in the second file, and decrypts the second file through the decryption key.

For example, user a is a first object, user B is a second object, and user B selects a local picture to be shared with user a when user a and user B chat.

User B selects a certain picture 1 (first file) in the local. At this time, whether the user B intends to share or not is detected, prompting is carried out, and privacy is guaranteed not to be revealed.

And the user B selects privacy sharing, and when the system detects that the current sharing path is application X and the sharing object is user A in the application X, encryption processing is carried out through a system-level encryption suite. The specific encryption strategy is as follows:

using a common picture S (third file) in the encryption base as a reference picture, adding confusion parameters for the reference picture, including: the picture 1 is confusion encrypted by applying the application package name (first location information) of the X, the id (Identity document, identification file) of the user a and the decryption key1, and a new picture 1' is generated.

The decryption key1 is derived from a system level encryption and decryption suite, and the decryption key1 is generated according to the application package name of the application X and the id of the user A.

And if the operation that the user B shares the encrypted picture 1 'to the user A is detected, the system-level encryption suite packages the automatic picture 1' into the sharing suite. After the user B completes the sending of the sharing suite, the current users a and B see the sharing suite and the picture 1 'stored in the sharing suite, wherein the picture 1' displays the content and the picture S, which may be the same content or different content.

If the content displayed by the picture 1 'is the same as the content of the picture S, the encrypted data is added to the original picture S content, and after the picture 1' is received and decrypted by the user a, the content seen by the user a is still the content of the original picture S.

If the display content of the picture 1 'is different from that of the picture S, the confusion data is added on the original picture S content to generate a new picture 1'.

When user a receives the sharing suite, view picture 1'. When the sharing suite detects that the application currently viewing the picture is application X and the viewing user is a, the application is shown at the bottom of the picture 1': prompt information of "whether to decrypt".

If the user A selects decryption, the system level decryption suite obtains a decryption key1 through a built-in decryption function according to the confusion parameters including the application package name of the application X and the id of the user A, decrypts the picture 1', obtains the decrypted picture 1 and displays the decrypted picture 1 to the user A.

The specific decryption strategy is as follows:

firstly, a built-in encryption and decryption function is used, and a decryption key1 is obtained according to confusion parameters, including the name of an application packet of the application X and the id of the user A.

Then, adding confusion de-parameters for the picture 1', including the application package name of the application X, the id of the user A and the decryption key1, carrying out reverse confusion decryption on the picture 1', and restoring the picture 1 into the original picture 1.

Four key parameters are checked during decryption:

1. checking whether the current application is the original application X. If not, or if the picture is opened using another application, decryption will not be possible and user a can only see the encrypted picture 1'.

2. It is checked whether the user currently viewing picture 1' is user a. If not, decryption will not be possible and the user receiving picture 1 'will only see encrypted picture 1'. If it is sent to a certain group, it is verified whether the user looking at the picture is the user of this group, and if not, decryption cannot be performed.

3. And checking whether the current decryption strategy is performed based on the system-level encryption and decryption suite. If not, then no decryption will be possible and user A will only see encrypted picture 1'.

4. Check if the current decryption key is key1. If not, then no decryption will be possible and only the encrypted picture 1' will be seen.

Only if the 4 conditions are met, the decrypted data can be viewed, so that only specific users can be ensured to decrypt and view the shared content under the specific conditions.

The embodiment of the application encrypts the file shared by the user based on the system-level encryption and decryption suite, so that the file actually shared by the user can be checked only when the file is displayed on a specific display position, otherwise, the file after disguising can be checked, and the security when the privacy information is shared is effectively protected.

In some embodiments of the application, the encryption suite is a second encryption suite, the second encryption suite being an encryption suite associated with the first location information of the first object;

and encrypting the first file through the third file and the encryption suite to obtain a second file, wherein the method comprises the following steps:

receiving a third input;

and responding to the third input, and carrying out confusion encryption on the first file through a second encryption suite and a third file by taking the object information of the first object as a confusion parameter to obtain a second file, wherein a decryption key of the second file is determined according to the object information of the first object.

In the embodiment of the present application, the second encryption suite is specifically an application-level encryption suite, and when a user shares a file through an application program associated with the second encryption suite, the file may be encrypted by the second encryption suite. The shared object of the encrypted file can perform decryption processing on the encrypted file in response to the corresponding application-level decryption suite.

Specifically, when the first file is encrypted by the application-level encryption suite, that is, the second encryption suite, the user inputs object information of a first object of the objects that the user wishes to share.

The second encryption suite takes object information of the first object as confusion parameters, carries out confusion encryption processing on the first file according to the third file, obtains a second file after processing, and shares the second file to the first object through a sharing path indicated by first sharing path information associated with the second encryption suite.

When the first object receives the second file, and when the shared object is determined to be matched with the object indicated by the object information of the first object, the shared object can determine a decryption key based on the object information of the first object through a decryption suite of the current application program, and the second file is decrypted through the decryption key.

For example, when user a and user B chat through a chat application, user B selects a local picture to be shared with user a.

The user B selects a certain picture 1 (first file) in the local area, and uses the encryption sharing function of the current chat application. And using a common picture S (third file) in the encryption library as a reference picture, adding confusion parameters including id (Identity document, identification file) of a user A and a decryption key1 for the reference picture, carrying out confusion encryption on the picture 1, and generating a new picture 1'.

The decryption key1 comes from an application-level encryption and decryption suite, and the decryption key1 is generated according to the id of the user A and a built-in encryption algorithm of the application and encryption suite.

After the user B completes the sending of the sharing suite, the current users a and B see the picture 1'.

User a clicks to view picture 1'. When the user currently viewing the picture is detected as A, displaying at the bottom of the picture 1': prompt information of "whether to decrypt".

If the user A selects decryption, the application level decryption suite obtains a decryption key1 through a built-in decryption function according to the confusion parameter including the id of the user A, decrypts the picture 1', obtains the decrypted picture 1 and displays the decrypted picture 1 to the user A.

The specific decryption strategy is as follows:

firstly, a built-in encryption and decryption function is used, and a decryption key1 is obtained according to confusion parameters including the id of a user A.

Then, adding confusion de-parameters to the picture 1', wherein the confusion de-decryption parameters comprise id and decryption key1 of the application user A, and carrying out confusion de-encryption on the picture 1' in a reverse direction to restore the picture 1 into the original picture 1.

Three key parameters are checked during decryption:

1. it is checked whether the user currently viewing picture 1' is user a. If not, decryption will not be possible and the user receiving picture 1 'will only see encrypted picture 1'. If it is sent to a certain group, it is verified whether the user looking at the picture is the user of this group, and if not, decryption cannot be performed.

2. And checking whether the current decryption strategy is carried out based on the application-level encryption and decryption suite. If not, then no decryption will be possible and user A will only see encrypted picture 1'.

3. Check if the current decryption key is key1. If not, then no decryption will be possible and only the encrypted picture 1' will be seen.

Only if the 3 conditions are met, the decrypted data can be viewed, so that only specific users can be ensured to decrypt and view the shared content under the specific conditions.

According to the embodiment of the application, the file shared by the user is encrypted based on the application-level encryption and decryption suite, so that only a specific object can view the file actually shared by the user, otherwise, only the disguised file can be seen, and the security in sharing the privacy information is effectively protected.

In some embodiments of the present application, when the display position of the second file is the display position indicated by the first position information and the decryption result of the second file is that the decryption is successful, displaying at least part of the first file in the second electronic device;

and displaying the second file in the second electronic device when the display position of the second file is not the display position indicated by the first position information or when the display position of the second file is the display position indicated by the first position information but the decryption result of the second file is that the decryption is failed.

In the embodiment of the application, when the second file is received by a certain sharing object, whether the display position for displaying the second file currently is consistent with the display position indicated by the first position information is judged, and it can be understood that the display position designated by the user is equivalent to limiting the sharing way of the sharing file on one hand and is equivalent to limiting the object users capable of receiving the sharing file on the other hand.

If the display position of the second file is the display position indicated by the first position information, the second file can be decrypted, if the decryption result of the second file is that the decryption is successful, the current sharing object is determined to be the correct object of the file which the user wants to share, at the moment, at least part of the first file is displayed, and the content which the user really wants to share is displayed to the current object.

If the current display position of the second file is not the display position indicated by the first position information, the file shared by the user is transmitted in an irrelevant path, the second file is displayed at the moment, and the content of the first file possibly containing the user privacy is hidden through the second file, so that the user privacy is prevented from being revealed.

If the current display position of the second file is the display position indicated by the first position information, but the decryption of the second file by the object fails, which also indicates that the file shared by the user is not received by the correct object, the second file is displayed.

For example, fig. 3A, fig. 3B, fig. 3C, fig. 3D, fig. 3E, and fig. 3F respectively show interface diagrams of a file sharing method according to an embodiment of the present application, and as shown in fig. 3A, a chat window 300 includes a user a, a user B, a user C, and a user D.

As shown in fig. 3B, if the user D wishes to share the first file 302 with the user B, a first input may be made to the first file 302 to select the first file 302, and in the chat window 300, the user B is selected as the target user.

At this time, the first file 302 is encrypted to obtain an encrypted second file 304, and as shown in fig. 3C, the user D sends the second file 304 to the chat window 300.

At this time, the picture seen by the user D is shown in fig. 3D, the picture seen by the user B is shown in fig. 3E, and the picture seen by the user a is shown in fig. 3F, that is, only the user B can see the second file 304 shared by the user D, and the user a and the user C cannot perceive the behavior of the user D to share the file with the user B.

For example, when user a, user B, user C and user D chat in group, user D selects a local picture to be shared with user B.

In the local selection of the user D, a certain picture 1 is shared by using an application, and the application prompts: please set the target sharing user. At this time, the user D selects the user B in the N groups as the target user.

At this time, the encryption suite encrypts the shared content of the user D, that is, the picture 1, to ensure that the privacy is not compromised, and the specific encryption policy includes:

a common picture S in the encryption base is used as a reference picture. And adding confusion parameters including the identification id of the N groups, the id of the user B and the decryption key1 for the reference picture, carrying out confusion encryption on the picture, and generating a new picture 1'.

The decryption key1 is generated by the encryption suite through a built-in encryption algorithm according to the identification id of the N groups and the id of the user B.

After the user D sends the shared content to the N group, since the user a and the user C are not target users, the picture 1' cannot be seen, and the user a and the user C cannot perceive that the user B and the user D in the group share the picture.

And the user B clicks the view picture 1', and the application detects that the user currently viewing the picture 1' is the user B in the N groups, and displays prompt information whether decryption is performed.

After the user B selects decryption, a decryption suite in the application is utilized, a decryption key1 is obtained by utilizing a decryption function according to confusion parameters including the identification id of the N group and the id of the user B, and a confusion parameter is added for the picture 1', wherein the confusion parameters include the identification id of the N group, the id of the user B and the decryption key1, and the picture 1' is subjected to confusion decryption in a reverse direction, so that an original picture 1 which the user D wants to share is obtained.

The embodiment of the application can ensure that the privacy file shared by the user can be seen by a specific object only in a specific application program, can effectively prevent the privacy information of the user from being seen by irrelevant people, can prevent the privacy of the user from being spread in irrelevant channels, effectively protects the privacy of the user and prevents the privacy from being revealed.

In some embodiments of the present application, the first file includes a first file portion and a second file portion, the first object includes a first sub-object and a second sub-object, and the position information of the first sub-object and the position information of the second sub-object are both first position information;

encrypting the first file, including:

taking object information and first position information of a first sub-object as confusion parameters, and performing first encryption processing on a first file part; and performing a second encryption process on the second file portion by taking object information and the first position information of the second sub-object as confusion parameters;
