Fig. 2 is a schematic structural diagram of another communication device according to an embodiment of the present application.
As shown in fig. 2, in one embodiment, the communication device further comprises an identification module 140 and a sensor module 150, wherein the identification module 140 and the sensor module 150 are both connected to the processing module 120;
the identification module 140 is configured to identify a user identity and transmit an identification result to the processing module 120;
the sensor module 150 is configured to acquire environmental information and transmit the environmental information to the processing module 120;
the processing module 120 is further configured to receive the recognition result and/or the environmental information;
the first preset condition comprises that the identification result meets a first preset requirement and/or the environment information meets a second preset requirement, and the environment information comprises position information.
In an embodiment of the present application, the sensor module of the communication device may acquire environmental information. The sensor module may include at least one of a temperature sensor, a photoelectric sensor, a humidity sensor, and the like, and the environmental information may be, for example, temperature information sensed by the temperature sensor, photoelectric information sensed by the photoelectric sensor, and humidity information sensed by the humidity sensor. The particular sensors included in the sensor module may be adjusted according to the task undertaken by the communication device.
The recognition module 140 may be a biometric module, such as a face recognition module, a fingerprint recognition module, a pupil recognition module, or a voice recognition module. The sensor module 150 may include at least one of a temperature sensor, a position sensor, a humidity sensor, and an illumination intensity sensor. Meanwhile, it should be understood that the identification module can also identify the authority level of the transmitted information (such as files, etc.).
The identity of the user of the communication device can be identified by the identification module 140, for example, whether the user is a predetermined user of the communication device. The preset user may be a user who is preset to use the communication apparatus. When the user is the preset user, the processing module 120 may transmit the second target information to the sending module 130, and the sending module 130 receives the second target information, modulates the second target information into a second visible light signal, and sends the second visible light signal. The first preset requirement can be that the user is a first preset user with the information transmission authority.
The sensor module 150 may acquire current environmental information and transmit the current environmental information to the processing module 120, and the processing module 120 may determine whether the current transmission environment is safe according to the current environmental information, for example, in a case that the sensor module 150 includes a position sensor, the processing module 120 may determine whether the communication device is currently located at a preset position, where the preset position may be a position where information can be safely transmitted. In the case that the current transmission environment is safe (the communication apparatus is currently located at the preset position), the processing module 120 may transmit the second target information to the sending module 130, and the sending module 130 receives the second target information, modulates the second target information into a second visible light signal, and sends the second visible light signal. The second preset requirement may be that the current position is a first preset position where information transmission can be performed.
Therefore, whether the current information transmission environment is safe or not can be judged through the identification module and the sensor module, and under the condition that the current information transmission environment is safe, the visible light signal carrying information can be sent out through the sending module. Therefore, the information transmission is carried out under the condition that the current information transmission environment is safe, and the safety and the confidentiality of the information transmission can be ensured.
Meanwhile, in another embodiment, after obtaining the first target information, the processing module 120 is further configured to write device information of the communication device into the first target information to obtain second target information.
Wherein the device information comprises at least one of: time information of the communication device, identification information of the communication device, geographical location information of the communication device.
The device information of the communication device may include at least one of current time information, geographical location information of the communication device, and identification information of the communication device (e.g., a serial number of the communication device). The second object information is obtained by writing the device information into the first object information, and the transmission path of information can be grasped by the device information in the second object information (when and where, a certain information is received or transmitted via the communication device having the serial number 99).
In this way, after the device information of the communication device is written into the first target information to obtain the second target information, and the second target information is sent to the sending module, the transmission path of the information can be grasped through the device information in the second target information.
Optionally, in this embodiment of the present application, the communication devices may further send the device information to a remote server, and the remote server may generate an information relay diagram according to the device information sent by each communication device, where the information relay diagram includes a propagation path of information.
Before the processing module 120 writes the device information of the communication device into the first target information to obtain the second target information, the processing module 120 is further configured to generate, according to the first target information, a received information check code corresponding to the first target information received by the communication device (i.e., a check code of the first target information received by the communication device); and sends the received information check code to the sending module 130, and sends the received information check code to the sending device through the sending module 130 in the communication device. In the embodiment of the present application, the check code may be generated according to content data of a corresponding carrier (e.g. a file), and is not always transmitted with the carrier. Taking a carrier as an example, since the appendix part of the file comprises information such as a file transmission path and the like, the file transmission path is continuously updated in the transmission process, so that the file check code can be generated in real time.
After receiving the received information check code, the sending device generates a sent information check code (the check code of the first target information sent by the sending device), compares the received information check code with the sent information check code in the sending device, and sends the comparison result to the communication device.
It is understood that during the information transmission, a transmission error may occur, for example, during the process of the sending device sending the first target information to the communication device, such as a loss of part of data in the first target signal; it may result in the first target information received by the communication device not being identical to the first target information sent by the sending device. In order to avoid this, whether the first target information has an error in the transmission process may be determined by comparing the received information check code with the transmitted information check code, and if the transmission has an error, the transmitting device may retransmit the first target signal, or the communication device may retransmit the first target signal.
After receiving the comparison result, if the comparison result indicates that the transmission is correct, the communication device can also send a visible light signal indicating that the destruction operation is performed to the sending device, and after receiving the visible light signal, the sending device can destroy the first target information in the sending device.
After the communication device can also send a visible light signal indicating that the destruction operation is performed to the sending device, the processing module 120 in the communication device can obtain the second target information according to the first target information.
After the first target information in the sending device is destroyed by the sending device, the connection between the sending device and the communication device can be disconnected. And connecting the communication device with the receiving device, and sending the second target information to the receiving device.
It should be understood that, in the embodiment of the present application, the disconnection between the sending device and the communication device is not necessarily after the destruction of the first target information. In a possible implementation manner, taking the first target information as an example of file transmission, after the file transmission is completed and the verification is completed, the communication device may transmit a subsequent processing signal of the original file to the sending device, and the sending device determines a subsequent specific processing flow according to the subsequent processing signal.
Similarly, after the communication device sends the second target information to the receiving device, the receiving device may also generate, according to the second target information, a received information check code corresponding to the second target information received by the receiving device (i.e., a check code of the second target information received by the communication device); and sending the received information check code to a communication device. After receiving the received information check code, the communication device generates a transmitted information check code (the check code of the second target information transmitted by the transmitting device), compares the received information check code with the transmitted information check code in the transmitting device, and then transmits the comparison result to the receiving device. After receiving the comparison result, if the comparison result indicates that the transmission is correct, the receiving device may further send a visible light signal indicating that the destruction operation is performed to the communication device, and after receiving the visible light signal, the communication device may destroy the second target information in the communication device.
When the transmitting device and the communication device perform information transmission (that is, when the transmitting device transmits the first target information to the communication device), the transmitting device needs to be connected to the communication device, and after the transmission between the transmitting device and the communication device is finished (that is, after the transmitting device destroys the first target information in the transmitting device), the connection between the transmitting device and the communication device is disconnected, and then the communication device is connected to the receiving device to perform information transmission between the communication device and the receiving device (the communication device obtains the second target information from the first target information and transmits the second target information to the receiving device).
In another embodiment, the first target information may correspond to a first visible light signal and a second visible light signal, the first target information includes tag information and content information, the tag information includes a security level of the first target information, the tag information corresponds to the first visible light signal, and the content information corresponds to the second visible light signal;

the processing module 120 is configured to receive the tag information and determine whether the tag information meets a second preset condition, and control the receiving module 110 to receive the second visible light signal if the tag information meets the second preset condition;
the receiving module 110 is further specifically configured to receive the second visible light signal, demodulate the second visible light signal to obtain content information, and transmit the content information to the processing module 120;
the processing module 120 is further configured to receive the content information from the receiving module 110.
Wherein the second preset condition comprises that the security level of the first target information is matched with the authority level of the communication device and/or the authority level of the user of the communication device.
It is understood that the receiving module 110 may obtain the first target information by receiving the first visible light signal and the second visible light signal. The tag information corresponds to the first visible light signal to indicate that the first visible light signal carries the tag information of the first target information, and the content information corresponds to the second visible light signal to indicate that the second visible light signal carries the content information of the first target information.
The tag information may include an information type and a security level of the first target information.
It is understood that the information types and security levels of the various information may be different, and the authority level of each communication device and the authority level of each user of each communication device may be different, and in the case where the security level of the information is higher, only the communication device with the higher authority level and/or the user with the higher authority level may receive the information, and the communication device with the lower authority level and/or the user with the lower authority level may not receive the information with the higher security level.
Thus, the second predetermined condition may include that the security level of the first target information matches the authority level of the communication device and/or the authority level of the user of the communication device. The matching of the security level of the first object information with the authority level of the communication device may be that the security level of the first object information is less than or equal to the authority level of the communication device, and the matching of the security level of the first object information with the authority level of the user of the communication device may be that the security level of the first object information is less than or equal to the authority level of the user of the communication device.

In this way, the receiving module 110 first receives the first visible light signal carrying the tag information of the first target information, and then receives the second visible light signal carrying the content information of the second target information when the tag information corresponding to the first visible light signal meets the second preset condition. It is ensured that the communication device receives information corresponding to the authorization level of the communication device and/or the user of the communication device, further ensuring the security of the information.
The processing module 120 may further determine an information type of the first target information according to the tag information before determining whether the tag information satisfies a second preset condition, where the information type includes general information and important information. If the first target information is common information, the first target information is stored in a common information memory (the communication device comprises a common information memory), and then the first target information is directly sent to a receiving device through a sending module. If the first target information is important information, it is determined whether the tag information satisfies a second preset condition through the processing module 120.

The processing module 120 may control the receiving module 110 to receive the second visible light signal and the third visible light signal when the tag information satisfies a second preset condition. The disposal information is used for indicating that the first target information of the sending device is destroyed by adopting a preset method.
After the communication device receives the comparison result indicating correct transmission, the processing module 120 is further configured to parse the disposal information from the first target information, and modulate the disposal information into a visible light signal through a sending module and send the visible light signal to the sending device. After receiving the visible light signal, the sending device demodulates the treatment information, and treats (for example, destroys) the first target information of the sending device according to the treatment information. In this embodiment of the present application, destroying the information may include a plurality of destroying methods, for example, only the information to be destroyed (for example, the first target information) may be deleted, all the information in the storage area where the information to be destroyed is located may be deleted, or the storage may be formatted in a low-level manner, even a self-destruction module existing in the device may be started (the communication device, the sending device, and the receiving device may include the self-destruction module), and all the device may be destroyed, so as to achieve the purpose of keeping secret. And the information can be destroyed according to different destruction methods according to different confidentiality grades of the information.

In this way, the information associated with the first target information can be displayed to the user for viewing through the display module; the processing module transmits the first target information to the display module under a third preset condition, so that only the information associated with the first target information can be displayed to a user having the authority of viewing the information associated with the first target information or the information associated with the first target information can be displayed through the display module only in a safe environment, and the safety of the information associated with the first target information is ensured.
