Description
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to an information sharing method and device.
Background
As wearable devices are widely applied to various scenes, the wearable devices are increasingly unable to keep away from the lives of people. When the user is in the environment of limited carrying or not carrying the terminal, insufficient terminal electric quantity, terminal communication failure and the like, the Bluetooth broadcast mode can be sent out through the wearable device, and then any device supporting receiving the Bluetooth broadcast in the environment receives the Bluetooth broadcast sent by the wearable device, so that the message content can be checked. Taking a rescue scene as an example, the current wearable device sends user personalized information such as user location information and heartbeat information … … in a broadcast manner, so that personal information of a wearable device holder is leaked to a great extent, and a potential safety hazard exists.
Disclosure of Invention
The application provides an information sharing method and device, which are used for solving the problem that leakage of user personalized information is easily caused when wearable equipment sends information.
In a first aspect, an embodiment of the present application provides an information sharing method, where the method includes: the method comprises the steps that first information sent by second equipment is received by first equipment; the first information comprises a device identification of at least one device; if the first device determines that the device identifier of the at least one device comprises the device identifier of the first device, acquiring a second decryption algorithm; the first equipment receives second information sent by the second equipment; the second information is generated after the second device encrypts the transfer content; and the first equipment decrypts the second information according to the second decryption algorithm to obtain the transfer content.
Based on the scheme, the function of the wearable device is upgraded, and the message is divided into two messages to be sent when the wearable device sends the message (the wearable device after the function upgrade is the second device, or may be called as the sending device), where the first message is the device identifiers of some devices specified by the user, and the second message is generated by encrypting the content that the user needs to deliver, so that when the receiving device (i.e. the first device) receives the first message, the receiving device can obtain the second decryption algorithm to decrypt the second message received by the receiving device to obtain the delivered content only when the device identifiers of the receiving device (i.e. the first device) and the device identifiers of some devices specified by the sending device are matched, and this way can realize that the delivered content is viewed only by some devices specified by the user, thereby protecting the personal privacy of the sender of the message. In the method, for the wearable device with the upgraded function, when the first information does not include the device identifier of the wearable device, the second information is not processed; for the wearable device with the function not upgraded, the second decryption algorithm is not available, so that the transferred content cannot be viewed, and the purpose that only some devices specified by the user can view the second information is achieved.
In a possible implementation method, before the first device receives the first information sent by the second device, the method further includes: the first equipment receives indication information sent by the second equipment; the indication information is used for indicating a response mode of the first device to the second device.
Based on the scheme, in different scenes (such as a scene needing to dial 119, or a scene needing to dial 110; such as a scene that a user in the bed wishes to spread out a voice message delivered by the user, or such as a scene that the user in the bed only wishes to be listened by a holder of a receiving device appointed by the user currently for the voice message delivered by the user), when the user sends the message to the receiving device through the sending device, different trigger modes can be applied to the sending device, wherein each trigger mode corresponds to indication information, and the indication information is used for indicating that a device appointed by the user and capable of responding to the user at a later stage can respond to the user according to a preset response mode. By the method, the scene of message sharing can be enriched.
In a possible implementation method, the first information is generated by the second device after encrypting a device identifier of the at least one device; the first device, before determining that the device identity of the at least one device includes the device identity of the first device, further includes: the first equipment determines a first decryption algorithm corresponding to the indication information according to the response mode; and the first equipment decrypts the first information according to the first decryption algorithm to obtain the equipment identifier of the at least one equipment.
Based on the scheme, when the sending device sends the first information, the sending device can also encrypt the device identifier of the device which is specified by the user and can see the delivered content, so that when the receiving device receives the indication information, if the indication information can be interpreted, that is, the receiving device can know which response mode the indication information corresponds to, the receiving device can obtain the first decryption algorithm which can be used for decrypting the first information, and some old devices in the environment can be filtered through the method. Specifically, in the iterative upgrade process of the device, some old devices do not support the function of interpreting the indication information, so that the old devices cannot know what meaning the indication information expresses after receiving the indication information, and the upgrade device can support the function of interpreting the indication information, so that the upgrade device can acquire the first decryption algorithm corresponding to the indication information after receiving the indication information, thereby operating subsequent first information and second information.
In one possible implementation, the first device sends the indication information, the first information, and the second information to a third device.
Based on the scheme, when the receiving equipment cannot respond to the sending equipment in time, the receiving equipment can respond to the sending equipment through the same message sending mode and the receiving equipment trusted by the receiving equipment is authorized, so that the response mode to the sending equipment is enriched.
In one possible implementation, the delivery content is user input information or user personalized information collected by the second device.
Based on the scheme, in the scene of information sharing, the user can transmit the content which the user wants to transmit outwards in various ways, for example, the user can actively input the content, for example, the user can use the expression forms of voice input, keyboard input, video input and the like, for example, the user can also actively transmit personalized information which is stored in the local part of the device by the device through the mode of device import, for example, the device can actively transmit outwards after the user permission.
In one possible implementation, the first information and the second information are respectively encapsulated in a broadcast message and transmitted.
Based on the scheme, when the sending device sends the first information and the second information to the receiving device, the sending device sends the first information and the second information by respectively encapsulating the first information and the second information in the broadcast message, and the mode can realize that some upgrading devices which do not specify the device for the user do not need to decrypt the second information.
In one possible implementation, the device identification is a MAC address of the device.
Based on the scheme, the MAC address of the device can be used for identifying the device, so that the device can be distinguished accurately, and the MAC address of the device is used as the device identification, so that the device can be specified accurately.
In a second aspect, an embodiment of the present application provides an apparatus for information sharing, where the apparatus includes means for performing the method according to any one of the first aspect.
In a third aspect, an embodiment of the present application provides an information sharing apparatus, including:
a memory for storing a computer program;
a processor for calling a computer program stored in said memory and executing the method according to any of the first aspect according to the obtained program.
In a fourth aspect, the present application provides a computer-readable storage medium, which stores a computer program for causing a computer to execute the method according to any one of the first aspect.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Currently, for some scenes in which messages sent by terminals are limited, any device supporting receiving bluetooth broadcast in the environment can receive the bluetooth broadcast sent by the wearable device in a manner of sending the bluetooth broadcast by using the wearable device, and then the message content can be viewed. However, in this method, since a trusted relationship between the transmitting device and the receiving device is not established, leakage of personal information of the holder of the transmitting device is likely to occur.
In view of the foregoing technical problem, an embodiment of the present application provides a possible system architecture, as shown in fig. 1, the system architecture includes a second device 110 and a first device 120, where the second device 110 is a message sending device, and the first device 120 is a message receiving device, where products of the second device 110 and the first device 120 may be the same or different, and the present application is not limited specifically. Further, the second device 110 is a relative concept to the first device 120, namely: the second device 110 is a device for sending a message to the first device 120, and meanwhile, the second device 110 may also be a device for receiving a message sent by another sending device; similarly, the first device 120 is a device for receiving a message sent by the second device 110, and meanwhile, the first device 120 may also be a device for sending a received message sent from the second device 110 to another receiving device.
It should be noted that, after receiving the message, the first device 120 determines whether or not to transmit the received message to another receiving device according to the actual situation of the holder of the first device 120, and includes: the holder of the first device 120 may choose to forward the received message to other receiving devices following the manner in which the received message was sent; of course, the holder of the first device 120 may also choose not to forward the message, but to process the message by itself, which is not specifically limited in this application.
In view of the above technical problem and the system architecture shown in fig. 1, an embodiment of the present application provides an information sharing method, as shown in fig. 2, the method includes the following steps:
In this step, the first device is a message receiving device, the second device is a message sending device, and in a process that the second device sends a message to the first device, the second device may send first information to the first device, where the first information includes a device identifier of at least one device.
Wherein the understanding of the at least one device can be illustrated by the following examples: for example, in a scenario where a message is not suitable for being disclosed in its entirety, such as a disease rescue scenario, the holder of the message sending device only wants some devices in the environment to receive rescue information sent out by the holder of the message sending device, so as to want the designated devices to respond to the message, and does not want all devices in the environment to receive rescue information sent out by the holder of the message sending device, because the rescue information may include sensitive information such as heart rate, blood pressure, etc. of the holder of the message sending device, so the holder of the message sending device may only want some people in the environment to see the sensitive information, and thus, by designating some devices, it is helpful to ensure the personal privacy of the holder of the message sending device. As such, at least one device in the embodiments of the present application may be understood as a device that the second device determines may be responsive to the second device based on the user indication. When the second device detects that there are many devices in the environment, for example, a display list of the second device includes device identifiers of a large number of devices, then, when the holder of the second device determines to make the holder of one or several devices in the environment respond to the second device by making a selection, the user instruction may be to specify the device by means of voice input of the device identifier, or to specify the device by means of clicking the device identifier, or to specify the device by means of manual input of the device identifier, which is not specifically limited in the present application.
In some implementations of the present application, the first device may be a wearable device, such as a smart band, a smart watch, or the like, or may be a smart terminal, such as a mobile phone; the second device can be wearable equipment, for example be intelligent bracelet, smart watch etc. or can be intelligent terminal, for example for the cell-phone.
In some implementations of the present application, the device identification may be a MAC address of the device.
Since the MAC address of the device can be used to identify the device, and thus, the device can be accurately distinguished from the device, and therefore, the MAC address of the device is used as the device identifier, which is helpful for the user to accurately specify the device.
In this step, when the first device receives the first information, the first device matches the device identifier of itself (i.e., the first device) with the device identifier of the at least one device included in the first information, and if the first device determines that the device identifier of the at least one device includes the device identifier of itself (i.e., the first device) after the matching, the first device may obtain the second decryption algorithm.
By the method, the second decryption algorithm can be acquired only by some specified devices, and the second decryption algorithm cannot be acquired by unspecified devices.
In this step, for a scenario in which the second device sends a message to the first device, after the second device sends the first information to the first device, the second device may continue to send second information to the first device, where the second information is generated after the second device encrypts the transfer content.
In this way, by encrypting the transfer content, all devices in the environment cannot immediately check the message that the holder of the message sending device wants to transfer to the outside, thereby promoting the protection of the personal privacy of the holder of the message sending device.
It should be understood that, in the embodiment of the present application, the order in which the first device executes step 203, step 201, and step 202 is not limited. For example, the first device may perform step 203, step 201, and step 202 in a sequential order, or may perform step 201, step 203, and step 202, which is not limited in this application.
And step 204, the first device decrypts the second information according to the second decryption algorithm to obtain the transfer content.
In this step, the first device may decrypt the second information received by itself (i.e., the first device) according to the obtained second decryption algorithm, and then the first device may finally obtain the content that the holder of the second device wants to deliver, i.e., the delivery content.
The description is as follows: in the process of the iterative upgrade of the equipment, the upgraded equipment is distinguished from the old equipment. Among them, one important difference in function between the upgrading device and the old device is that: the upgrade device locally stores a second decryption algorithm that decrypts the second information, while the old device locally stores no second decryption algorithm that decrypts the second information. Thus, when the upgrading device is designated as a device that can respond by the holder of the message sending device, that is, the upgrading device is within range of at least one device, the upgrading device can acquire the second decryption algorithm from the local storage to decrypt the second information, and further view the transfer content of the message sending device; however, when the old device is designated as a device that can respond by the holder of the message sending device, the old device cannot acquire the second decryption algorithm because the second decryption algorithm for decrypting the second information is not locally stored, so that the old device cannot decrypt the second information, and further cannot view the content transferred by the message sending device. Therefore, by the method, the old devices in the environment can be effectively filtered, namely even if the old devices are in the range of at least one device, in other words, even if the old devices are the specified devices of the holders of the message sending devices, the old devices cannot acquire the transfer contents of the message sending devices, and therefore the protection of the personal privacy of the holders of the message sending devices is improved.
Based on the scheme, the function of the wearable device is upgraded, and the message is divided into two messages to be sent when the wearable device sends the message (the wearable device after the function upgrade is the second device, or may be called as the sending device), where the first message is the device identifiers of some devices specified by the user, and the second message is generated by encrypting the content that the user needs to deliver, so that when the receiving device (i.e. the first device) receives the first message, the receiving device can obtain the second decryption algorithm to decrypt the second message received by the receiving device to obtain the delivered content only when the device identifiers of the receiving device (i.e. the first device) and the device identifiers of some devices specified by the sending device are matched, and this way can realize that the delivered content is viewed only by some devices specified by the user, thereby protecting the personal privacy of the sender of the message. In the method, for the wearable device with the upgraded function, when the first information does not include the device identifier of the wearable device, the second information is not processed; for the wearable device with the function not upgraded, the second decryption algorithm is not available, so that the transferred content cannot be viewed, and the purpose that only some devices specified by the user can view the second information is achieved.
In some implementations of the present application, before the first device receives the first information sent by the second device, the method further includes: the first equipment receives indication information sent by the second equipment; the indication information is used for indicating a response mode of the first device to the second device.
For example, when a user sends a message to the outside through the second device, the user may send out the corresponding message based on different scenarios. If the holder of the second device is ill, he wants to make the designated device dial 120 when seeing the ill message, and if the holder of the second device encounters a fire, he wants to make the designated device dial 119 when seeing the fire rescue message, and if the holder of the second device is a sleeping platform assigned by the police, he wants to make the designated device know the content of the message detected by him when detecting the message in the sleeping platform, and other scenes are not illustrated one by one. Obviously, in the above-listed scenario, the holder of the second device may apply different triggering operations to the second device, and then the second device converts the triggering operation made by the user into corresponding indication information according to the mapping relationship between the preset triggering manner and the indication information, and then when the second device sends the indication information to the first device, and after the first device obtains the transfer content, the first device may know what response behavior the holder of the second device needs to make.
For example, for a scene in which 120 needs to be dialed in case of a disease, the holder of the second device may use a key triggering mode on the second device, and if the key "1" is pressed, the second device may convert the key behavior of the holder on the key "1" into an indication information, and if the indication information is converted into an indication information "001", the indication information received by the subsequent first device is "001", and the first device also clearly indicates that the response mode corresponding to "001" is the dialing 120.
For another example, for a scene where a fire needs to dial 119, the holder of the second device may trigger the second device by pressing a key, for example, pressing the key "2", the second device may convert the key behavior of the holder on the key "2" into an indication information, for example, into an indication information of "002", the indication information received by the subsequent first device is "002", and the first device also clearly indicates that the response mode corresponding to "002" is to dial 119.
For another example, for a scene of message delivery from the bottom of the bed, the holder of the second device may perform a key triggering on the second device, for example, if the key "3" is pressed, the second device may convert the key behavior of the key "3" by the holder into an indication information, for example, an indication information "003", the indication information received by the subsequent first device is "003", and the first device also knows that the corresponding response manner of "003" is that the corresponding response operation is performed on the holder of the second device later according to the understanding of the content of the message delivery.
It is noted that the triggering manner is not limited in the embodiments of the present application, and for example, the triggering manner may be key triggering, drag triggering, gesture triggering, or the like; in addition, the user may set the indication information corresponding to various scenes only in a single trigger mode (e.g., only key trigger, or only drag trigger, or only gesture trigger), or the user may set the indication information corresponding to various scenes in combination with multiple trigger modes (e.g., combination of key trigger and drag trigger, or combination of key trigger, drag trigger, and gesture trigger), which is not specifically limited in this application; in addition, the embodiment of the present application does not limit the expression of the indication information.
In some implementations of the present application, the delivery is user input information or user personalization information collected by the second device.
As in the case of the scenario of dialing 120 for the foregoing ailments, the user may not be required to actively input personal information at this time, but may instead implement the action in a preset manner. If the second device detects that the user presses the key "1", the second device can know that the user personalized information stored locally by the user (i.e. the second device) needs to be acquired by the second device according to a preset programming mechanism and then sent out after being encrypted as the transmission content.
The description is as follows: in the embodiment of the application, the user personalized information may be information such as position information, various index information of the body, and environment detection information of the user. As for the above scenario that the patient needs to dial 120, the personalized information of the user collected by the second device may include the location information of the user, because generally speaking, after receiving the rescue information, the 120 emergency center may find the object sending the rescue information according to the location information of the patient to rescue the patient.
As another example, in the scenario of the message transmission by the bedding, when the bedding faces a message that needs to be transmitted, the message can be transmitted in various manners, such as by voice input, keyboard input, video input, and the like, so that when the second device receives the transmission content input by the user, the transmission content can be encrypted and transmitted to the outside.
In some implementations of the present application, the first information and the second information are each encapsulated in a broadcast message for transmission.
For example, when the second device sends the first information and the second information to the first device, the second device sends the first information and the second information by respectively encapsulating the first information and the second information in a broadcast message, which can realize that some upgrading devices which do not specify devices for users do not need to decrypt the second information.
In some implementations of the present application, the first information is generated by the second device after encrypting a device identifier of the at least one device; the first device, before determining that the device identity of the at least one device includes the device identity of the first device, further includes: the first equipment determines a first decryption algorithm corresponding to the indication information according to the response mode; and the first equipment decrypts the first information according to the first decryption algorithm to obtain the equipment identifier of the at least one equipment.
For example, when the second device sends a message to the first device, the first information in the message includes a device identifier of at least one device; further, for the purpose of privacy protection of the device identifier of the at least one device, the second device may further encrypt the device identifier of the at least one device, and when encrypting the device identifier of the at least one device, the second device encrypts the device identifier of the at least one device according to a response manner, where different response manners correspond to different encryption algorithms. Therefore, the indication information sent by the second device to the first device may also be used to indicate a decryption algorithm for decrypting the encrypted device identifier of at least one device, that is, the indication information is used to indicate what decryption algorithm is specifically used for decrypting the first information. Therefore, when the first device receives the indication information, the first device decrypts the first information by matching the first decryption algorithm corresponding to the indication information, and obtains the device identifier of the at least one device.
The description is as follows: in the process of the iterative upgrade of the equipment, the upgraded equipment is distinguished from the old equipment. Among them, an important difference in function between the upgrading device and the old device is that: the upgrading device locally stores a first decryption algorithm for decrypting the first information, and the old device locally stores no first decryption algorithm for decrypting the first information. Therefore, when the upgrading equipment receives the indication information sent by the message sending equipment, the upgrading equipment can decrypt the first information by matching the first decryption algorithm corresponding to the indication information, so as to obtain the equipment identifier of at least one piece of equipment, and then the upgrading equipment can match the equipment identifier of the upgrading equipment with the equipment identifier of at least one piece of equipment and make a judgment on whether the equipment identifier of the upgrading equipment is in accordance with the equipment identifier of the at least one piece of equipment; when the old device receives the indication information sent by the message sending device, the old device cannot analyze what the indication information shows because the old device does not locally store the mapping relationship between the indication information and the first decryption algorithm, so that the old device cannot acquire the decryption algorithm for decrypting the first information according to the indication information, the purpose of preventing the old device in the environment from checking the contents transmitted by the holder of the second device is achieved, the possibility that the transmitted contents are checked by a plurality of devices is reduced, and the personal privacy protection of the holder of the message sending device is promoted.
In some implementations of the present application, the first device sends the indication information, the first information, and the second information to a third device.
For example, when the first device is an upgrade device, after receiving the indication information sent by the second device, after locally searching for the first decryption algorithm corresponding to the indication information, the first device decrypts the first information by using the first decryption algorithm, and determines the device identifier of the first device included in the device identifiers of the at least one device, so that the first device can locally obtain the second decryption algorithm for decrypting the second information, and decrypt the second information, thereby obtaining the delivered content. After the first device obtains the transfer content, the first device may perform the following three processing modes on the transfer content, including:
mode 1: and directly responding to the second device according to the transfer content. If the content transmitted by the second device is that the second device needs to be dialed 120, the holder of the first device can dial 120 to rescue the holder of the second device.
Mode 2: the delivered content is ignored, i.e. no response is made to the second device in case the transmitted message of the second device is not received. If the content transmitted by the second device is to dial 120 for the second device, the holder of the first device chooses not to dial 120.
Mode 3: the transfer is not responded to directly, but is forwarded out. If the second device sends a transfer that requires dialing 120 for the second device, and the holder of the first device cannot dial 120 for the holder of the second device for some personal reasons when receiving the transfer, then the first device may respond to the second device by forwarding the transfer to some devices of its own choosing in hopes of some devices that may be trusted by itself.
The above three modes enrich the mode of responding to the second device.
Based on the same concept, the embodiment of the present application provides an information sharing device, which includes a module for executing any method of the foregoing embodiments.
The embodiment of the present application provides an information sharing apparatus, which may specifically be a desktop computer, a portable computer, a smart phone, a tablet computer, a Personal Digital Assistant (PDA), and the like.
