Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures 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 data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Before describing the technical solutions provided by the embodiments of the present disclosure, an implementation environment related to the embodiments of the present disclosure will be described first. Fig. 1 is a schematic diagram of an implementation environment according to an embodiment of the disclosure, where the implementation environment may include at least two clients, and the implementation environment shown in fig. 1 is illustrated by using four clients as an example, and referring to fig. 1, the four clients 10 respectively operate different accounts, including, for example, an account a to an account D. The implementation environment may also include a server 20, and each client 10 may be communicatively coupled to the server 20. In addition, peer-to-peer communication between the various clients 10 may also be performed for direct interaction of data.

The client 10 may be any client that installs a social application providing a file sharing function such as instant messaging, and the server 20 may be an application server corresponding to the social application installed by the client 10.

Each of accounts a through D may be social application accounts, such as instant messaging accounts, for identifying a unique one of the communication users. The accounts can send and receive files to and from each other, and are sharing parties and shared parties, for example, the account a can be used as a sharing party, and share files to the accounts B to D through the corresponding clients 10, and at this time, the accounts B to D are used as shared parties, and receive the files shared by the account a through the corresponding clients 10; the account a may also be used as a shared party, and receive, through its corresponding client 10, a file shared by any one of the accounts B to D. It should be noted that, the client corresponding to an account refers to a client running the account.

For example, when sharing a file, the sharing party account may set a shared party account of the file to be shared through the corresponding client, and upload account information (such as an account ID) of the file to be shared and the shared party account to the server 20; the server 20 receives the file to be shared and the account information of the shared account corresponding to the file to be shared, and forwards the file to be shared to the client corresponding to the shared account based on the account information of the shared account, or sends a sharing message to the client corresponding to the shared account, so that the shared account downloads the file to be shared from the server 20 through the corresponding client.

Based on the above implementation environment, the embodiment of the disclosure provides a file sharing method. Fig. 2 is a flowchart of a file sharing method according to an exemplary embodiment, which is illustrated by the application of the file sharing method to a client, where the client may be the client 10 in the implementation environment shown in fig. 1. Referring to fig. 2, the file sharing method may include the steps of:

in step S21, at least one designated account to share the first file is determined in response to a sharing request of the target account for the first file.

The first file is a file to be shared by the target account, and may include, for example, but not limited to, one or more of a document, a picture, a video, an audio, and the like.

The user can log in the client side by using the target account, and after selecting a first file to be shared and setting a designated account for the first file to be shared, the sharing request for the first file is triggered by clicking a click sharing button and other operations on a user interface. Wherein the designated account may include, but is not limited to, one or more of a friend account of the target account, some or all of the accounts in the group, accounts of interest, and the like.

It should be noted that, the group refers to various types of groups added by the user account in instant messaging software or other social applications with instant messaging functions.

In step S22, sharing authorization information of the designated account is obtained.

In step S23, the first file is shared with the designated account according to the sharing authorization information of the designated account.

In embodiments of the present disclosure, the sharing authorization information of the designated account may include encryption information of the designated account, the authorized social relationship may include one or more of a key, an authorization code, a fingerprint of an owner of the designated account, a face image, and other biometric information, and the social relationship may include, for example, but not limited to: friend relationships, group relationships, praise relationships, and the like.

According to the file sharing method, the at least one designated account of the first file to be shared is determined, the sharing authorization information of the designated account is obtained, the first file is shared to the designated account according to the sharing authorization information, the designated account of the file to be shared is triggered, the sharing authorization information is provided to realize file sharing, all user accounts sharing the file participate in the file sharing authorization process, the triggering party of the file is not only relied, and the safety of the file sharing process is improved.

In order to enable those skilled in the art to better understand the technical solution provided by the embodiments of the present disclosure, a detailed description is provided below of the file sharing method provided by the embodiments of the present disclosure.

First, with respect to the above step S21, in some optional embodiments, in response to a sharing request of the target account for the first file, the client may determine an account in the target group where the target account is located as a designated account to share the first file, and/or may determine an account in a friend list of the target account as a designated account to share the first file.

According to the method and the device, the target account can quickly share the first file. And the accounts in the friend list of the target account and/or the accounts in the target group are determined to be the designated accounts, and the files are shared to the designated accounts based on the sharing authorization information of the designated accounts with the association relation with the target accounts, so that the files can be prevented from being acquired by strange accounts without any relation with the target accounts, and the security of the shared files is further enhanced.

Of course, in other alternative embodiments, when the user logs in the client through the target account to share the first file, the user may also select the designated account to share the first file according to needs, for example, a part of accounts in the friend list may be marked or account information of the designated account to share the first file may be input, so that the account information is carried in the sharing request received by the client, and thus, the client determines the designated account based on the account information carried in the sharing request in response to the sharing request. The implementation mode is more flexible, and meets various file sharing requirements of users.

Secondly, for the step S22, the sharing authorization information of the designated account may be obtained through three modes of online obtaining, offline obtaining and self-generating. These three modes are described in detail below.

Embodiment one: and obtaining the sharing authorization of the appointed account on line.

As shown in fig. 3, in this embodiment, the step S22 specifically includes:

in step S221, a sharing authorization request is sent to the designated account, where the sharing authorization request is used to request the designated account to set sharing authorization information for the first file.

In step S222, the sharing authorization information returned by the designated account is received.

Optionally, the client corresponding to the target account may send the sharing authorization request to the client corresponding to the designated account through a peer-to-peer communication manner, or may send the sharing authorization request to a server, where the server forwards the sharing authorization request to the client corresponding to the designated account, so as to set the sharing authorization information for the first file through the designated account. Correspondingly, the client corresponding to the designated account receives the sharing authorization information of the designated account and returns the sharing authorization information to the client corresponding to the target account in a point-to-point communication mode, or the sharing authorization information of the designated account is sent to a server and forwarded to the client corresponding to the target account through the server.

For example, when the account a (i.e. the target account) requests to share the target file from the account B to the account D (i.e. the designated account), the client sends a sharing authorization request to the account B to the account D respectively after receiving the request for sharing the target file from the account a, so as to request to obtain the sharing authorization information of the designated accounts set by the designated accounts respectively and return the sharing authorization information to the target accounts.

It can be understood that by means of online obtaining the sharing authorization information of the designated account, the sharing authorization information of the designated account does not need to be stored in the local or server of the client, so that on one hand, occupation of storage resources of the local or server of the client can be reduced, on the other hand, leakage of the sharing authorization information of the designated account can be avoided, safety of the sharing authorization information is improved, and safety of sharing files is further improved.

Embodiment two: and acquiring the sharing authorization information of the designated account offline.

As shown in fig. 3, in this embodiment, the step S22 includes the following step S223 or step S224:

in step S223, sharing authorization information of the designated account stored in advance is read locally.

The client corresponding to the target account may locally store the sharing authorization information of the designated account in advance, where the sharing authorization information may be sent to the client corresponding to the target account in advance after the designated account confirms the permission granted to the target account to share the first file.

In step S224, the sharing authorization information of the designated account is obtained from the server.

And the sharing authorization information is uploaded to the server for storage after the designated account confirms authorization.

For example, the client corresponding to the target account may send a sharing authorization request carrying respective account information of the target account and the designated account to the server, and the server checks the target account based on the account information of the target account, reads the sharing authorization information of the designated account after the verification is passed, and returns the sharing authorization information to the client corresponding to the target account. It can be appreciated that the sharing authorization information of the designated account is stored in the server for the client to download and use from the server when needed, and compared with the sharing authorization information of the designated account stored locally in the client, the sharing authorization information can reduce occupation of local storage resources of the client.

It can be appreciated that in this embodiment, by storing the sharing authorization information of the designated account in the client local or server in advance, so that the client can read locally or download from the server when needed, compared with an online acquisition mode, the problem that the sharing authorization information of the designated account cannot be acquired timely due to untimely response of the designated account can be avoided, and the time waiting for online authorization of the designated account is reduced, thereby improving the efficiency of sharing files.

Embodiment III: and generating sharing authorization information of the designated account.

In some practical application scenarios, for example, the target account is urgent to share the first file with the designated account, but the designated account is offline and cannot respond to the sharing authorization request of the target account in time, and the designated account does not send the sharing authorization information to the client local or the server in advance, for which, the embodiment may be used to generate the sharing authorization information of the designated account. Specifically, as shown in fig. 3, the step S22 may include:

in step S225, social relationship information between the target account and the designated account is obtained.

In step S226, sharing authorization information of the designated account is generated based on the social relationship information.

For example, if the obtained social relationship information between the target account and the designated account indicates that the target account and the designated account are in a friend relationship, sharing authorization information of the designated account may be generated.

For example, the account a (i.e. the target account) is urgent to share the target file with the accounts B to D (i.e. the designated accounts), and the designated accounts are all offline, and the account a and the designated accounts are all in a friend relationship, and the respective sharing authorization information of the designated accounts may be generated and the target file may be shared with the designated accounts based on the respective sharing authorization information of the designated accounts in response to the sharing request of the account a for the target file.

It can be understood that, through the embodiment, on one hand, the sharing authorization information of the designated account does not need to be stored in the local client side and the server in advance, so that occupation of storage resources of the local client side and the server can be reduced, and the sharing authorization information of the designated account can be prevented from being revealed; on the other hand, the online authorization of the appointed account is not required to be waited, so that the problem that sharing authorization information of the appointed account cannot be timely obtained due to untimely response of the appointed account can be avoided, the time for waiting the online authorization of the appointed account is reduced, and the file sharing efficiency is further improved.

It should be noted that, in the specific implementation, any one of the above three embodiments for obtaining the sharing authorization information of the specified account may be adopted, or a combination of one or more embodiments may also be adopted. For each designated account of the first file to be shared, whether the sharing authorization information of the designated account is stored in the local client or the server or not can be queried, and if yes, the sharing authorization information of the designated account is directly read from the local client or the server; if not, sending a sharing authorization request to the appointed account, and receiving sharing authorization information returned by the appointed account. If the sharing authorization information returned by the designated account is not received within the preset time after the sharing authorization request is sent, acquiring social relation information between the target account and the designated account, and generating the sharing authorization information of the designated account based on the social relation information.

Finally, with respect to step S23, in an alternative embodiment, the sharing authorization information of the designated account may include encryption information of the first file by the designated account, where the encryption information may include, for example, but not limited to: a key, an authorization code, a fingerprint of the owner of the designated account, a facial image, and the like. Accordingly, as shown in fig. 3, the step S23 may include:

in step S231, the first file is encrypted based on the encryption information of each of all the designated accounts to be shared with the first file.

In step S232, the encrypted first file is shared with the designated account.

In the embodiment, the files shared by the target accounts are encrypted and then are shared based on the encryption information of all the designated accounts, so that the files shared by the target accounts can be decrypted and checked only by collecting the encryption information of all the designated accounts, and further all the designated accounts sharing the files participate in the file sharing decryption process, and the method does not depend on the triggering party of the shared files any more, and improves the safety of the file checking process.

In other embodiments of the disclosure, the target account may be used as a sharer to share the file according to the file sharing method described in the foregoing embodiments, or may be used as a sharee to receive the file shared by the sharee. The process of receiving and viewing files shared by other accounts by the target account is described in detail below.

Specifically, as shown in fig. 4, the file sharing method according to the embodiment of the disclosure further includes:

step S24, receiving a second file shared by any account through the target account.

Any account may be an account having a friend relationship with the target account (i.e. an account in a friend list China), may be an account in the same group as the target account, or may be an account having no relation with the target account, which is not limited in the embodiment of the present disclosure.

The second file is a file shared by any account, and may include, for example, but not limited to, one or more of a document, a picture, video, audio, and the like.

Step S25, obtaining the sharing authorization information of all the designated accounts of the second file.

Step S26, processing the second file according to the sharing authorization information of each of all the designated accounts of the second file, so as to view through the target account.

In the embodiment of the disclosure, the file viewing is realized by triggering the designated users sharing the file to provide the sharing authorization information, so that all user accounts sharing the file participate in the file viewing process, and the method and the device are not only dependent on the triggering party of the sharing file, thereby improving the safety of the file viewing process.

In the step S25, the sharing authorization information of all the designated accounts of the second file may be obtained in both an online manner and an offline manner. Next, these two modes will be described respectively.

Embodiment one: on-line acquisition mode

In this embodiment, as shown in fig. 5, step S25 may include:

in step S251, for each designated account of the second file, the designated account is requested to obtain the sharing authorization information of the designated account.

Optionally, the client corresponding to the target account may directly send the sharing authorization request to the client corresponding to the designated account through a peer-to-peer communication manner, or the sharing authorization request may be sent to a server, and the server forwards the sharing authorization request to the client corresponding to the designated account, so as to verify the identity of the target account through the designated account and set the sharing authorization information for the second file after the verification is passed.

In step S252, an authorization response returned by the designated account is received, where the authorization response includes account information and encryption information of the designated account.

Optionally, the client corresponding to the target account may also receive the sharing authorization information of the designated account returned by the client corresponding to the designated account through a peer-to-peer communication manner, or may receive the sharing authorization information of the designated account forwarded by the server.

By the method for acquiring the sharing authorization information of the designated account on line, the sharing authorization information of the designated account does not need to be stored in the local or server of the client, so that the occupation of storage resources of the local or server of the client can be reduced, the sharing authorization information of the designated account can be prevented from being revealed, the security of the sharing authorization information is improved, and the security of the sharing file is further enhanced.

Embodiment two: off-line acquisition mode

In this embodiment, as shown in fig. 5, step S25 may include step S253 or step S254 described below.

In step S253, the sharing authorization information of each of all the designated accounts of the locally stored second file is read.

The client sides corresponding to all the target accounts can locally store sharing authorization information of all the designated accounts in advance, and the sharing authorization information can be sent to the client sides corresponding to the target accounts in advance after the designated accounts confirm the permission granted to the target accounts to view the second files.

In step S254, the sharing authorization information of each of all the designated accounts of the second file is acquired from the server.

And the sharing authorization information is uploaded to the server for storage after the assigned account confirms authorization.

The client may send an authorization decryption request carrying account information of the target account and all designated accounts to the server, and the server checks the target account based on the account information of the target account, reads the shared authorization information of each designated account after the verification is passed, and returns the shared authorization information to the client corresponding to the target account. It can be appreciated that the sharing authorization information of each of all the designated accounts is stored in the server, so that the client can download and use the sharing authorization information from the server when needed, and compared with the method that the sharing authorization information of each of all the designated accounts is stored locally in the client, the method can reduce occupation of local storage resources of the client.

It can be appreciated that in this embodiment, by storing the sharing authorization information of each of all the designated accounts in the local or server of the client in advance, so that the client can directly read from the local or download from the server when needed, compared with an online acquisition mode, the problem that the sharing authorization information of the designated account cannot be acquired in time due to untimely response of the designated account can be avoided, and the time for waiting for online authorization decryption of the designated account is reduced, thereby improving the viewing efficiency of the shared file.

Accordingly, the manner of obtaining the sharing authorization information of the designated account in the step S25 is different, and the step S26 may process the second file according to different embodiments.

In an alternative embodiment, for the sharing authorization information of the designated account acquired in the online manner, as shown in fig. 5, the step S26 may include:

in step S261, the account information and the encryption information in the received authorization response are verified based on the locally stored encryption information of the designated account.

In the implementation, the account information in the received authorization response and the pre-stored account information of the designated account can be subjected to consistency comparison so as to judge whether the designated account is authorized or not. And comparing the encryption information in the received authorization response with the prestored encryption information of the appointed account in a consistency manner so as to judge whether the encryption key is correct or not.

In step S262, if the account information and the encryption information in the received authorization response are verified, the second file is decrypted based on the encryption information of each of all the designated accounts of the second file.

Accordingly, if the account information in the received authorization response is consistent with the prestored account information of the designated account and the encryption information in the authorization response is consistent with the prestored encryption information of the designated account, determining that the account information and the encryption information in the authorization response pass the verification.

And if authorization responses returned by all the designated accounts are received and account information and encryption information in the authorization responses are checked to pass, decrypting the second file based on the respective encryption information of all the designated accounts.

It can be understood that, by the embodiment, after the authorization response returned to all the designated accounts passes the verification, the second file is decrypted based on the respective encryption information of all the designated accounts, so that the content of the second file can be prevented from being stolen by an illegal account, and the security of the second file is further enhanced.

In another alternative embodiment, for the sharing authorization information of the designated account acquired in the offline manner, as shown in fig. 5, the step S26 may include:

in step S263, for each designated account of the second file, a social relationship between the designated account and the target account is obtained.

In step S264, if the social relationship between each designated account of the second file and the target account accords with the social relationship permitted to be authorized by the designated account, the second file is decrypted based on the encryption information of each designated account corresponding to the second file, where the sharing authorization information of the designated account further includes the social relationship permitted to be authorized by the designated account.

Wherein the designated account allows authorized social relationships may include, for example, one or more of relationships, group relationships (i.e., in the same group), and the like. For example, the designated account may set the social relationship allowing authorization as a friend relationship, that is, the account having a friend relationship with the designated account is granted with permission to view the second file, and if the target account and the designated account are friend relationships, the target account is confirmed to be authorized by the designated account, so that encryption information of the designated account may be read to decrypt the second file.

If the social relationship between the target account and each designated account meets the social relationship allowed to be authorized by the designated account, the target account can be confirmed to obtain the permission granted by all the designated accounts to view the second file, and then the encryption information of each designated account can be read and the second file can be decrypted based on the encryption information so as to view the content of the second file through the target account.

It can be appreciated that in this embodiment, whether the target account obtains the permission of viewing the second file granted by the designated account is determined by the preset social relationship allowing authorization of the designated account, compared with a mode of waiting for each designated account to return an authorization response to process the second file based on the authorization response, the method of avoiding the fact that the second file cannot be processed in time due to untimely response of the designated account can be avoided, the time of waiting for response of the designated account is reduced, the processing time of the second file is further shortened, and the file viewing efficiency is improved. And the social relation between the target account and the appointed account is introduced in the decryption process, so that the relation between the second file and all related accounts is further enhanced.

It should be noted that the two embodiments of step S25 and step S26 may be adopted at the same time. Specifically, for each designated account of the second file, the social relationship allowed to be authorized by the designated account may be queried first, and whether the social relationship between the target account and the designated account and the target account accords with the social relationship allowed to be authorized by the designated account is determined; and if the social relationship between the target account and the designated account and the social relationship between the target account and the designated account are in accordance with the permission of the designated account for authorization, confirming that the designated account is authorized by the target account. If the social relationship between the target account and the designated account does not accord with the social relationship allowed to be authorized by the designated account, sending an authorization decryption request to the designated account to request the designated account to authorize to view the second file, and receiving an authorization response returned by the designated account; and then, checking the account information and the encryption information in the authorization response based on the pre-stored account information and the encryption information of the designated account, and if the verification is passed, confirming that the target account is authorized by the designated account. And under the condition that the target account is authorized by all the designated accounts, decrypting the second file based on the encryption information of each designated account.

Fig. 6 is a flowchart of a file sharing method according to another exemplary embodiment, which is illustrated by the application of the file sharing method to a server, where the server may be the server 20 in the implementation environment shown in fig. 1. Referring to fig. 6, the file sharing method may include the steps of:

in step S61, a sharing request of a target account for a target file is received, where the sharing request carries account information of at least one designated account to share the target file.

The target file is a file to be shared by the target account, and may include, for example, but not limited to, one or more of a document, a picture, a video, an audio, and the like.

In step S62, sharing authorization information of the designated account is obtained based on the account information of the designated account.

In step S63, the target file is shared with the designated account according to the sharing authorization information.

According to the file sharing method, file sharing is achieved by triggering the designated account of the file to be shared to provide sharing authorization information, all user accounts sharing the file participate in the file sharing authorization process, the triggering party of the file sharing is not relied, and the safety of the file sharing process is improved.

First, for the above step S62, the sharing authorization information of the designated account may be obtained through three modes of online obtaining, offline obtaining and self-generating. These three modes are described in detail below.

As shown in fig. 7, in this embodiment, the step S62 may include:

in step S621, a sharing authorization request is sent to the client running the designated account based on the account information of the designated account, where the sharing authorization request is used to request the designated account to set the sharing authorization information for the target file.

The sharing authorization request may carry account information of the target account and file information of the target file (such as ID of the target file), so as to set sharing authorization information of the target file through the designated account.

In step S622, sharing authorization information of the designated account returned by the client running the designated account is received.

It can be understood that by means of online obtaining the sharing authorization information of the designated account, the sharing authorization information of the designated account does not need to be stored in the server in advance, so that on one hand, occupation of storage resources of the server can be reduced, on the other hand, leakage of the sharing authorization information of the designated account can be avoided, safety of the sharing authorization information is improved, and safety of sharing files is further improved.

For example, as shown in FIG. 8, account A (i.e., the target account) uploads the target file to the server and requests that the target file be shared with Account B through Account D (i.e., the designated account). After receiving the sharing request of the account A on the target file, the server respectively sends sharing authorization requests to clients running the designated accounts so as to request to acquire the sharing authorization information of each designated account. And the clients corresponding to the designated accounts respectively respond to the sharing authorization request, set the sharing authorization information of the designated accounts respectively and return the sharing authorization information to the server. And the server receives the sharing authorization information of each designated account to process the target file, and shares the target file with the designated accounts.

As shown in fig. 7, in this embodiment, the step S62 may include:

in step S623, the locally stored sharing authorization information of the designated account is read based on the account information of the designated account.

The sharing authorization information of the designated account is preset and uploaded to the server.

It can be appreciated that in this embodiment, by storing the sharing authorization information of the designated account in the server in advance, so as to be directly read and used when needed, compared with an online acquisition mode, the method can avoid the problem that the sharing authorization information of the designated account cannot be acquired in time due to untimely response of the designated account, and reduce the time of waiting for authorized sharing of the designated account, thereby improving the efficiency of sharing files.

In some practical application scenarios, for example, the target account is urgent to share the first file with the designated account, but the designated account is offline and cannot respond to the sharing authorization request of the target account in time, and the designated account does not send the sharing authorization information to the server in advance, for which the embodiment may be used to generate the sharing authorization information of the designated account. Specifically, as shown in fig. 7, the step S62 may include:

In step S624, a social relationship between the designated account and the target account is obtained based on the account information of the designated account.

In step S625, sharing authorization information of the designated account is generated based on the social relationship between the designated account and the target account.

For example, the account a (i.e. the target account) is urgent to share the target file with the accounts B to D (i.e. the designated accounts), and the designated accounts are all offline, and the account a and the designated accounts are all in a friend relationship, and the server may generate the respective sharing authorization information of the designated accounts and share the target file with the designated accounts based on the respective sharing authorization information of the designated accounts in response to the sharing request of the account a for the target file.

It can be appreciated that, through the embodiment, on one hand, the sharing authorization information of the designated account does not need to be stored in the server in advance, so that occupation of storage resources of the server can be reduced, and the sharing authorization information of the designated account can be prevented from being revealed; on the other hand, the online authorization of the appointed account is not required to be waited, so that the problem that sharing authorization information of the appointed account cannot be timely obtained due to untimely response of the appointed account can be avoided, the time for waiting the online authorization of the appointed account is reduced, and the file sharing efficiency is further improved.

It should be noted that, in the specific implementation, any one of the above three embodiments for obtaining the shared authorization information of the specified account may be adopted, or a combination of one or more embodiments may be adopted. For each designated account to be shared with the first file, whether the sharing authorization information of the designated account is stored in the server or not may be queried, and if yes, the sharing authorization information of the designated account is directly read; if not, sending a sharing authorization request to the appointed account, and receiving sharing authorization information returned by the appointed account. If the sharing authorization information returned by the designated account is not received within the preset time after the sharing authorization request is sent, acquiring social relation information between the target account and the designated account, and generating the sharing authorization information of the designated account based on the social relation information.

Next, with respect to the above step S63, in an alternative embodiment, as shown in fig. 7, the above step S63 may include:

in step S631, the target file is stored after being encrypted based on the encryption information of each of all the designated accounts to share the target file.

In step S632, the encrypted sharing message of the target file is sent to the client running the designated account.

In other embodiments of the present disclosure, as shown in fig. 9, the method further includes:

in step S64, a request for viewing the target file by any account is received.

Any account may be a designated account of the target file, or may be other accounts other than the designated account, for example, other accounts in a friend list of the target account, or other accounts in the same group with the target account, or may be other accounts having no relation with the target account, which is not limited in the embodiments of the present disclosure.

In step S65, the respective sharing authorization information of all the designated accounts to be shared with the target file is obtained.

In step S66, the target file is processed according to the sharing authorization information of each of all the designated accounts of the target file, and the processed target file is returned to the account requesting to view the target file.

In the embodiment of the disclosure, the designated user triggering the shared file provides the sharing authorization information to realize file viewing, so that all user accounts sharing the file participate in the file viewing process, and the method does not depend on the triggering party of the shared file any more, thereby improving the safety of the file viewing process.

In the step S65, the sharing authorization information of all the designated accounts of the target file may be obtained in both an online manner and an offline manner. Next, these two modes will be described respectively.

Embodiment one: on-line acquisition mode

In this embodiment, as shown in fig. 10, step S65 may include:

in step S651, for each designated account in which the target file is to be shared, an authorized decryption request is sent to the client running the designated account.

In step S652, an authorization response returned by the client running the specified account is received, the authorization response including account information of the specified account and encryption information of the target file.

It should be noted that, the implementation process of this embodiment is similar to that of the embodiment shown in fig. 5, and in particular, please refer to the description of the embodiment shown in fig. 5, for redundancy reduction, no further description is given here.

By the method for acquiring the sharing authorization information of the designated account on line, the sharing authorization information of the designated account does not need to be stored in the server in advance, so that the occupation of storage resources of the server can be reduced, the sharing authorization information of the designated account can be prevented from being revealed, the safety of the sharing authorization information is improved, and the safety of the sharing file is further enhanced.

Embodiment two: off-line acquisition mode

In this embodiment, as shown in fig. 10, step S65 may include:

in step S653, the sharing authorization information of each of all the designated accounts of the locally stored target file is read.

It can be appreciated that in this embodiment, by storing the respective sharing authorization information of all the designated accounts in the server in advance, so that the server can directly read the sharing authorization information from the local when needed, compared with an online acquisition mode, the problem that the sharing authorization information of the designated accounts cannot be acquired in time due to untimely response of the designated accounts can be avoided, and the time for waiting for authorization decryption of the designated accounts is reduced, so that the viewing efficiency of the shared file is improved.

In an alternative embodiment, for the sharing authorization information of the designated account acquired in the online manner, as shown in fig. 10, the step S66 may include:

in step S661, the account information and the encryption information in the received authorization response are verified based on the locally stored encryption information of the designated account.

In step S662, if the account information and the encryption information in the received authorization response are verified, the target file is decrypted based on the encryption information of each of all the designated accounts of the target file.

It can be understood that, through the embodiment, the target file is decrypted based on the respective encryption information of all the designated accounts after the authorization response returned by all the designated accounts passes the verification, so that the content of the target file can be prevented from being stolen by an illegal account, and the security of the target file is further enhanced.

In another alternative embodiment, for the sharing authorization information of the designated account acquired in the offline manner, as shown in fig. 10, the step S66 may include:

in step S663, for each designated account in which the target file is to be shared, a social relationship between the designated account and the account requesting to view the target file is obtained.

In step S664, if the social relationship between each designated account to be shared with the target file and the account requesting to view the target file conforms to the social relationship of the designated account, decrypting the target file based on the encryption information of each designated account corresponding to the target file, wherein the sharing authorization information of the designated account further includes the social relationship permitted to be authorized by the designated account.

It should be noted that the two embodiments of step S65 and step 66 may be adopted at the same time. For example, as shown in fig. 8, an account B requests to view a target file shared by an account a (i.e., a target account), and a server responds to a file viewing request of the account B for the target file, and checks the social relationship allowed by each of three designated accounts, namely an account B, an account C and an account D, corresponding to the target file. If the account C is queried to set the authorized social relationship as a friend relationship and the social relationship between the account B and the account C is a friend relationship, the account B can be determined to acquire the authority granted by the account C to view the target file, so that an authorization decryption request is not required to be sent to the account C. The server also sends an authorization decryption request to account B and account D, respectively, to request permission to be granted to view the target file. Then, the server receives an authorization response returned by the account B aiming at the authorization decryption request, verifies the account information and the encryption information in the authorization response returned by the account B based on the pre-stored account information and the encryption information of the account B, and if the verification is passed, the account B can be determined to acquire the authority granted by the account B for checking the target file; meanwhile, the server also receives an authorization response returned by the account D for the authorization decryption request, checks the account information and the encryption information in the authorization response returned by the account D based on the pre-stored account information and the encryption information of the account D, and if the account information and the encryption information pass the check, the account B can be determined to acquire the authority granted by the account D for viewing the target file. And under the condition that the account B is determined to acquire the authority granted by all the designated accounts for viewing the target file, decrypting the target file based on the encryption information of all the designated accounts, and returning the decrypted target file to the account B. Further, the server may also return the decrypted target file to account C and account D.
