[0064] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0065] Figure 1 This is a schematic diagram of the main flow of the remote control method for a digital currency wallet provided according to the first embodiment of the present invention; as shown. Figure 1 As shown, the remote control method for a digital currency wallet provided in this embodiment of the invention is applied to a digital currency platform and mainly includes:

[0066] Step S101: Set remote control trigger conditions according to business security requirements, and generate remote control instructions when the remote control trigger conditions are met; wherein, the remote control instructions indicate the wallet number and operation method corresponding to the target digital currency wallet terminal.

[0067] According to an embodiment of the present invention, the remote management module of the digital currency platform monitors the stored risk wallet number lists such as blacklists and graylists, and monitors whether the digital currency platform or digital currency wallet terminal is subjected to network attacks. In order to formulate remote triggering conditions in combination with business security requirements, when the remote control triggering conditions are met, that is, when the security coefficient of the digital currency wallet in the current state is low and it is easy to cause economic losses, it is necessary to remotely control it under the digital currency platform to avoid potential risks and thus protect the security of users' digital currency assets.

[0068] Specifically, according to an embodiment of the present invention, the wallet number corresponding to the target digital currency wallet terminal is determined based on the remote control triggering conditions met; the remote control triggering conditions include one or more of the following:

[0069] The risk level of the digital currency platform and / or any digital currency wallet terminal exceeds the risk level threshold.

[0070] The list of risky wallet IDs stored in any digital currency wallet terminal is inconsistent with the list of risky wallet IDs stored in the digital currency platform.

[0071] According to embodiments of the present invention, the risk level threshold is set according to the actual situation, and the risks corresponding to digital currency platforms or digital currency wallet terminals mainly refer to things such as network attacks.

[0072] The digital currency platform monitors wallet accounts in different regions (such as nationwide or globally). It writes the corresponding IDs (which can be the same as the account ID or a unique ID) of risky wallet accounts into a risky wallet ID list. According to a specific implementation of this invention, the updated full list of risky wallet IDs, or the changed (added and deleted) risky wallet IDs, can be sent periodically to the digital currency wallet terminals in the corresponding regions. Alternatively, it can be updated in real time. The sending method and the amount of data sent can be adjusted according to actual circumstances.

[0073] With the above settings, a remote control command is generated when the remote control trigger conditions are met. The remote control command is then sent as a message to the corresponding digital currency wallet terminal (i.e., the target digital currency wallet terminal) via the BeiDou satellite system. This ensures that even if the digital currency wallet terminal is offline or the current mobile cellular communication signal is poor (in which case the signal is easily interfered with), remote control of the digital currency wallet terminal can be achieved, and the remote control effect can be guaranteed.

[0074] For example, according to an embodiment of the present invention, after the step of generating remote control instructions, the above method further includes:

[0075] Encrypt remote control commands;

[0076] Sign the encrypted remote control commands.

[0077] According to a specific embodiment of the present invention, a remote control instruction S (including but not limited to instruction code, instruction sequence number seqID, instruction issuance time, instruction sending message area (area / global short message, which can be used to determine the wallet number of the target digital currency wallet terminal receiving the remote control instruction, and Beidou communication module number) is encrypted using an agreed key to obtain S'; furthermore, the hash value of the encrypted remote control instruction S' can be signed to obtain a sign value according to actual needs.

[0078] According to an embodiment of the present invention, the generated remote control command can be encrypted according to a preset key (this is only an example, and any other existing encryption method can also be used) to prevent the remote control command from being tampered with. At the same time, signing the remote control command can be decided whether to execute it according to the actual situation. It is easy to understand that signing the remote control command helps the digital currency wallet terminal that subsequently receives the remote control command to verify the signature to ensure the legitimacy and credibility of the remote control command, and further protect the remote control effect.

[0079] Step S102: Send the remote control command to the BeiDou satellite system so that the BeiDou satellite system forwards the remote control command to the target digital currency wallet terminal in the offline state in the form of a message according to the wallet number, so as to realize the remote control of the target digital currency wallet terminal in the offline state.

[0080] Furthermore, according to an embodiment of the present invention, the aforementioned remote control instruction includes a transaction restriction instruction, which causes the target digital currency wallet terminal that receives the transaction restriction instruction to stop offline transactions.

[0081] Optionally, when the remote control triggering conditions include "the risk level of the digital currency platform and / or any digital currency wallet terminal exceeds the risk level threshold", sending a transaction restriction instruction to the corresponding digital currency wallet terminal (i.e. the target digital currency wallet terminal) helps the target digital currency wallet terminal to lock the wallet terminal and temporarily stop transactions after receiving the transaction restriction instruction.

[0082] Optionally, according to embodiments of the present invention, the remote control instruction may further include an updated list of risky wallet numbers. When the remote control triggering condition includes "the list of risky wallet numbers stored in any digital currency wallet terminal is inconsistent with the list of risky wallet numbers stored in the digital currency platform," the target digital currency wallet terminal, upon receiving the remote digital instruction, determines whether the counterparty's wallet number belongs to the updated list of risky wallet numbers. If it does, meaning the counterparty's digital currency wallet is a risky digital currency wallet, the transaction is suspended; if it does not, meaning the counterparty's digital currency wallet is not a risky digital currency wallet, the transaction can continue. Through the above settings, different remote control instructions can be generated according to the actual situation and the met remote control triggering conditions, enabling remote control of the user's digital currency wallet terminal even in situations with poor mobile cellular communication signals, especially offline, thus ensuring the security of the user's digital currency wallet assets.

[0083] Preferably, according to an embodiment of the present invention, the above method further includes:

[0084] Digital currency platforms can send remote control commands via broadcast, multicast, or unicast.

[0085] With the above settings, different sending methods can be flexibly selected based on the number and region of the target digital currency wallet terminals corresponding to the transmitted remote control commands, as well as the type of remote control commands being transmitted, thereby improving the efficiency of sending remote control commands.

[0086] According to the technical solution of this invention, by setting remote control trigger conditions according to business security requirements, and generating remote control instructions when the remote control trigger conditions are met, the remote control instructions indicate the wallet number and operation mode corresponding to the target digital currency wallet terminal. The remote control instructions are sent to the BeiDou satellite system, so that the BeiDou satellite system forwards the remote control instructions to the offline target digital currency wallet terminal in the form of a message, thereby achieving remote control of the target digital currency wallet terminal in an offline state. This overcomes the technical problem in existing methods where it is difficult to effectively remotely control digital currency wallets in an offline state, resulting in low security and poor remote control performance. Furthermore, in offline mode, the remote control instructions generated by the digital currency platform are sent to the digital currency wallet terminal via the BeiDou satellite system to achieve remote control of the offline digital currency wallet, significantly improving the security of the digital currency wallet terminal, enhancing the remote control effect, and improving the anti-interference capability of the forwarded information.

[0087] Figure 2 This is a schematic diagram of the main flow of the remote control method for a digital currency wallet provided according to the second embodiment of the present invention; as shown. Figure 2 As shown, the remote control method for a digital currency wallet provided in this embodiment of the invention, applied to the BeiDou satellite system, mainly includes:

[0088] Step S201: Receive a remote control instruction sent by the digital currency platform, wherein the remote control instruction indicates the wallet number and operation method corresponding to the target digital currency wallet terminal.

[0089] Specifically, according to an embodiment of the present invention, the BeiDou satellite system receives remote control commands sent by the digital currency platform through the BeiDou gateway. In a specific implementation of this embodiment, the digital currency platform sends the remote control commands to the BeiDou satellite system in a transparent transmission manner (i.e., transparent transmission, meaning it only needs to transmit the required services to the destination node while ensuring transmission quality, without processing the transmitted services; this is merely an example, and existing transmission methods that can guarantee transmission quality can also be used). The BeiDou satellite system uses the BeiDou module corresponding to the digital currency platform to receive the remote control commands sent by the digital currency platform through the BeiDou gateway. The BeiDou gateway primarily serves as a medium connecting the digital currency platform and the BeiDou satellite system (mainly connecting the BeiDou communication module under the BeiDou satellite system, referred to as the BeiDou module).

[0090] According to an embodiment of the present invention, since digital currency platforms often need to send remote control commands in large quantities (such as in the case of updating the list of risky wallet numbers, it is often necessary to send remote control commands to multiple digital currency wallet terminals in the area (mainly for digital currency wallet terminals in the area with poor signal or offline status), in this case, the Beidou gateway can be used to send the remote control commands to the appropriate Beidou module, and then forward them to multiple digital currency wallet terminals via the Beidou satellite system.

[0091] Step S202: Encode the remote control command according to the BeiDou message protocol to obtain the target message.

[0092] Through the above settings, remote control commands are encoded into messages according to the BeiDou message protocol, enabling offline forwarding of these commands using the BeiDou satellite system's unique short message communication capabilities. Furthermore, since existing mobile cellular communications such as 2G / 3G / 4G / 5G, NB-IoT, and Wi-Fi have limited coverage and are easily interfered with in emergencies, the BeiDou satellite system's communication capabilities can also be used to forward remote control commands when mobile cellular communication signals are weak.

[0093] Specifically, according to an embodiment of the present invention, after the step of encoding the remote control command according to the BeiDou message protocol to obtain the target message, the following steps are included:

[0094] The remote control commands are encoded according to the BeiDou message protocol to obtain the message;

[0095] The message is split according to the message transmission capability of the BeiDou satellite system to obtain the target message.

[0096] According to a specific embodiment of the present invention, the BeiDou communication module determines the short message communication capability to be used based on the area of ​​the transmitted signal, such as a 560-bit transmission capability for global short messages and a 14,000-bit capability for regional short messages; if the length (S'+sign) of the encoded message of the remote control command to be sent exceeds the load of a single message, the BeiDou module is responsible for splitting the long message into multiple short messages for transmission.

[0097] According to embodiments of the present invention, the single communication capability (i.e., the payload of a single transmitted message and the corresponding time interval) of the BeiDou satellite system varies depending on the radiation range of the transmitted / sent information. If the length of the message determined after encoding the remote control command exceeds the single message transmission capability of the BeiDou satellite system, the message can be split into multiple short messages (i.e., target messages).

[0098] Step S203: The target message is forwarded to the target digital currency wallet terminal according to the wallet number, so that the target digital currency wallet terminal decodes the target message to obtain the remote control instruction, and realizes remote control in offline state according to the operation mode indicated in the remote control instruction.

[0099] According to a specific embodiment of the present invention, the target message is sent through the BeiDou short message antenna, the signal is received by the BeiDou satellite and relayed and sent down; if there are multiple short messages, they are sent separately.

[0100] Furthermore, according to an embodiment of the present invention, the remote control command also indicates the Beidou communication module number corresponding to the target digital currency wallet terminal; forwarding the target message to the target digital currency wallet terminal according to the wallet number includes:

[0101] Based on the BeiDou communication module number and wallet number, the target message is forwarded to the target digital currency wallet terminal; the number of the target digital currency wallet terminals can be one or more.

[0102] Optionally, according to an embodiment of the present invention, a remote control command in the form of a message is sent to the Beidou communication module of the target digital currency wallet according to the Beidou communication module number and the wallet number, so that the Beidou communication module can decode the remote control command in the form of a message, thereby enabling the target digital currency wallet to decrypt and verify the signature of the corresponding remote control command after decoding, and realize remote control in offline state or under weak signal conditions according to the operation mode in the remote control command.

[0103] The above settings enable remote control of the digital currency wallet terminal even when it is offline or when the mobile cellular signal is weak (in which case the signal is easily interfered with), and ensure the effectiveness of the remote control.

[0104] According to the technical solution of this invention, by receiving remote control instructions sent by a digital currency platform, wherein the remote control instructions indicate the wallet number and operation mode corresponding to the target digital currency wallet terminal; encoding the remote control instructions according to the BeiDou message protocol to obtain a target message; and forwarding the target message to the target digital currency wallet terminal according to the wallet number, the target digital currency wallet terminal decodes the target message to obtain the remote control instructions and realizes remote control in offline mode according to the operation mode indicated in the remote control instructions. Therefore, this overcomes the technical problem in existing methods where it is difficult to effectively remotely control digital currency wallets in offline mode, resulting in low security and poor remote control performance. Furthermore, in offline mode, the remote control instructions generated by the digital currency platform are sent to the digital currency wallet terminal through the BeiDou satellite system to realize remote control of the offline digital currency wallet, achieving a significant improvement in the security of the digital currency wallet terminal, enhanced remote control performance, and improved anti-interference capability of the forwarded information.

[0105] Figure 3 This is a schematic diagram of the main flow of the remote control method for a digital currency wallet provided according to the third embodiment of the present invention; as shown. Figure 3 As shown in the embodiment of the present invention, the remote control method for a digital currency wallet is applied to a digital currency wallet terminal and mainly includes:

[0106] Step S301: Receive the target message forwarded by the BeiDou satellite system.

[0107] Specifically, according to an embodiment of the present invention, for a target message forwarded by the BeiDou satellite system, the BeiDou communication module (corresponding to the BeiDou communication module number of the target digital currency wallet terminal indicated in the remote control command) installed on the target digital currency wallet terminal receives the target message, so that the BeiDou communication module can subsequently decode the target message to obtain the remote control command. Specifically, after the BeiDou communication module of the target digital currency wallet terminal decodes and obtains the remote control command, it can send the remote control command to the decryption module of the target digital currency wallet terminal for decryption processing through middleware. The middleware is responsible for listening to BeiDou short message notifications and submits the encrypted BeiDou short message to the digital currency wallet through serial port, USB, bus, etc.; the middleware can exist independently or be integrated with the digital currency wallet as needed.

[0108] Step S302: Decode the target message to obtain the remote control instruction; wherein the remote control instruction indicates the operation mode corresponding to the target digital currency wallet terminal.

[0109] Optionally, according to embodiments of the present invention, if the target message includes multiple short messages, the above method further includes:

[0110] The remote control commands are obtained by combining the decoded portions of multiple short messages.

[0111] Furthermore, according to embodiments of the present invention, if the decoded remote control command undergoes encryption and signature processing by the digital currency platform; the above also includes:

[0112] Decrypt the remote control commands;

[0113] Verify the signature corresponding to the decrypted remote control command.

[0114] According to an embodiment of the present invention, the encrypted remote control command can be decrypted according to a preset key (this is only an example, and any other existing encryption method can also be used). The digital currency wallet decrypts the command to obtain information such as the command code, command sequence number seqID, and command issuance time. The remote control module then executes the corresponding remote control operation according to the business rules. At the same time, the digital currency wallet terminal that receives the remote control command verifies the signature to ensure the legitimacy and trustworthiness of the remote control command, further guaranteeing the effectiveness of the remote control.

[0115] Step S303: Perform the corresponding operation according to the operation method to achieve remote control in offline state.

[0116] Specifically, according to embodiments of the present invention, the aforementioned remote control instruction includes a transaction restriction instruction, which causes the target digital currency wallet terminal that receives the transaction restriction instruction to stop offline transactions. That is, when the remote control triggering condition includes "the risk level corresponding to the digital currency platform and / or any digital currency wallet terminal exceeds the risk level threshold", the target digital currency wallet terminal locks the wallet terminal after receiving the transaction restriction instruction, and can temporarily stop transactions.

[0117] Optionally, according to embodiments of the present invention, the remote control instruction may further include an updated list of risky wallet IDs. When the remote control triggering condition includes "the list of risky wallet IDs stored in any digital currency wallet terminal is inconsistent with the list of risky wallet IDs stored in the digital currency platform," the target digital currency wallet terminal, upon receiving the remote digital instruction, determines whether the counterparty's wallet ID belongs to the updated list of risky wallet IDs. If it does, meaning the counterparty's digital currency wallet is a risky digital currency wallet, the transaction is suspended; if it does not, meaning the counterparty's digital currency wallet is not a risky digital currency wallet, the transaction can continue. Through the above settings, remote control of the user's digital currency wallet terminal is possible even in situations with poor mobile cellular communication signals, especially offline, thus ensuring the security of the user's digital currency wallet assets.

[0118] According to the technical solution of this invention, by receiving target messages forwarded by the BeiDou satellite system, decoding the target messages to obtain remote control instructions, wherein the remote control instructions indicate the corresponding operation mode of the target digital currency wallet terminal, and performing corresponding operations according to the operation mode to achieve remote control in offline mode, this overcomes the technical problem in existing methods that make it difficult to effectively remotely control digital currency wallets in offline mode, resulting in low security and poor remote control effect of digital currency wallets. Furthermore, in offline mode, the remote control instructions generated by the digital currency platform are sent to the digital currency wallet terminal through the BeiDou satellite system to achieve remote control of the offline digital currency wallet, thereby significantly improving the security of the digital currency wallet terminal, enhancing the remote control effect, and improving the anti-interference capability of the forwarded information.

[0119] Figure 4 This is a schematic diagram of the main modules of the remote control device for a digital currency wallet provided according to the fourth embodiment of the present invention; as shown. Figure 4 As shown, the remote control device 400 for a digital currency wallet provided in this embodiment of the invention is installed on a digital currency platform and mainly includes:

[0120] The remote control instruction generation module 401 is used to set remote control trigger conditions according to business security requirements, and generate remote control instructions when the remote control trigger conditions are met; wherein, the remote control instruction indicates the wallet number corresponding to the target digital currency wallet terminal and the operation method.

[0121] According to an embodiment of the present invention, the remote management module of the digital currency platform monitors the stored risk wallet number lists such as blacklists and graylists, and monitors whether the digital currency platform or digital currency wallet terminal is subjected to network attacks. In order to formulate remote triggering conditions in combination with business security requirements, when the remote control triggering conditions are met, that is, when the security coefficient of the digital currency wallet in the current state is low and it is easy to cause economic losses, it is necessary to remotely control it under the digital currency platform to avoid potential risks and thus protect the security of users' digital currency assets.

[0122] Specifically, according to an embodiment of the present invention, the wallet number corresponding to the target digital currency wallet terminal is determined based on the remote control triggering conditions met; the remote control triggering conditions include one or more of the following:

[0123] The risk level of the digital currency platform and / or any digital currency wallet terminal exceeds the risk level threshold.

[0124] The list of risky wallet IDs stored in any digital currency wallet terminal is inconsistent with the list of risky wallet IDs stored in the digital currency platform.

[0125] According to embodiments of the present invention, the risk level threshold is set according to the actual situation, and the risks corresponding to digital currency platforms or digital currency wallet terminals mainly refer to things such as network attacks.

[0126] The digital currency platform monitors wallet accounts in different regions (such as nationwide or globally). It writes the corresponding IDs (which can be the same as the account ID or a unique ID) of risky wallet accounts into a risky wallet ID list. According to a specific implementation of this invention, the updated full list of risky wallet IDs, or the changed (added and deleted) risky wallet IDs, can be sent periodically to the digital currency wallet terminals in the corresponding regions. Alternatively, it can be updated in real time. The sending method and the amount of data sent can be adjusted according to actual circumstances.

[0127] With the above settings, under the condition of remote control triggering, the remote control command generation module 401 generates a remote control command, which is then sent to the corresponding digital currency wallet terminal (i.e., the target digital currency wallet terminal) in the form of a message via the Beidou satellite system. This enables remote control of the digital currency wallet terminal even when it is offline or when the current mobile cellular communication signal is poor (at which time the signal is easily interfered with), and ensures the effectiveness of remote control.

[0128] For example, according to an embodiment of the present invention, the remote control device 400 for the digital currency wallet further includes a processing module, which, after the step of generating remote control instructions, is used to:

[0129] Encrypt remote control commands;

[0130] Sign the encrypted remote control commands.

[0131] According to an embodiment of the present invention, the generated remote control command can be encrypted according to a preset key (this is only an example, and any other existing encryption method can also be used) to prevent the remote control command from being tampered with. At the same time, signing the remote control command can be decided whether to execute it according to the actual situation. It is easy to understand that signing the remote control command helps the digital currency wallet terminal that subsequently receives the remote control command to verify the signature to ensure the legitimacy and credibility of the remote control command, and further protect the remote control effect.

[0132] The sending module 402 is used to send remote control commands to the BeiDou satellite system, so that the BeiDou satellite system forwards the remote control commands to the target digital currency wallet terminal in offline state in the form of a message according to the wallet number.

[0133] Furthermore, according to an embodiment of the present invention, the aforementioned remote control instruction includes a transaction restriction instruction, which causes the target digital currency wallet terminal that receives the transaction restriction instruction to stop offline transactions.

[0134] Optionally, when the remote control triggering conditions include "the risk level of the digital currency platform and / or any digital currency wallet terminal exceeds the risk level threshold", sending a transaction restriction instruction to the corresponding digital currency wallet terminal (i.e. the target digital currency wallet terminal) helps the target digital currency wallet terminal to lock the wallet terminal and temporarily stop transactions after receiving the transaction restriction instruction.

[0135] Optionally, according to embodiments of the present invention, the remote control instruction may further include an updated list of risky wallet numbers. When the remote control triggering condition includes "the list of risky wallet numbers stored in any digital currency wallet terminal is inconsistent with the list of risky wallet numbers stored in the digital currency platform," the target digital currency wallet terminal, upon receiving the remote digital instruction, determines whether the counterparty's wallet number belongs to the updated list of risky wallet numbers. If it does, meaning the counterparty's digital currency wallet is a risky digital currency wallet, the transaction is suspended; if it does not, meaning the counterparty's digital currency wallet is not a risky digital currency wallet, the transaction can continue. Through the above settings, different remote control instructions can be generated according to the actual situation and the met remote control triggering conditions, enabling remote control of the user's digital currency wallet terminal even in situations with poor mobile cellular communication signals, especially offline, thus ensuring the security of the user's digital currency wallet assets.

[0136] Preferably, according to an embodiment of the present invention, the above-described sending module 402 is further configured to:

[0137] Remote control commands are sent to the BeiDou satellite system via broadcast, multicast, or unicast.

[0138] With the above settings, different sending methods can be flexibly selected based on the number and region of the target digital currency wallet terminals corresponding to the transmitted remote control commands, as well as the type of remote control commands being transmitted, thereby improving the efficiency of sending remote control commands.

[0139] According to the technical solution of this invention, by setting remote control trigger conditions according to business security requirements, and generating remote control instructions when the remote control trigger conditions are met, the remote control instructions indicate the wallet number and operation mode corresponding to the target digital currency wallet terminal. The remote control instructions are sent to the BeiDou satellite system, so that the BeiDou satellite system forwards the remote control instructions to the offline target digital currency wallet terminal in the form of a message, thereby achieving remote control of the target digital currency wallet terminal in an offline state. This overcomes the technical problem in existing methods where it is difficult to effectively remotely control digital currency wallets in an offline state, resulting in low security and poor remote control performance. Furthermore, in offline mode, the remote control instructions generated by the digital currency platform are sent to the digital currency wallet terminal via the BeiDou satellite system to achieve remote control of the offline digital currency wallet, significantly improving the security of the digital currency wallet terminal, enhancing the remote control effect, and improving the anti-interference capability of the forwarded information.

[0140] Figure 5This is a schematic diagram of the main modules of the remote control device for a digital currency wallet provided according to the fifth embodiment of the present invention; as shown. Figure 5 As shown, the remote control device 500 for a digital currency wallet provided in this embodiment of the invention is installed in the BeiDou satellite system and mainly includes:

[0141] The receiving module 501 is used to receive remote control instructions sent by the digital currency platform, wherein the remote control instructions indicate the wallet number and operation mode corresponding to the target digital currency wallet terminal.

[0142] Specifically, according to embodiments of the present invention, since digital currency platforms often need to send remote control commands in large quantities (such as in the case of updating a list of risky wallet numbers, it is often necessary to send remote control commands to multiple digital currency wallet terminals in the area (mainly for digital currency wallet terminals in the area with poor signal or offline status), in this case, the Beidou gateway can be used to send the remote control commands to a suitable Beidou module, and then forward them to multiple digital currency wallet terminals via the Beidou satellite system.

[0143] The encoding module 502 is used to encode the remote control command according to the BeiDou message protocol to obtain the target message and send the target message to the BeiDou satellite.

[0144] Through the above settings, remote control commands are encoded into messages according to the BeiDou message protocol, enabling offline forwarding of these commands using the BeiDou satellite system's unique short message communication capability. Furthermore, due to limitations in coverage and susceptibility to interference in emergency situations with existing mobile cellular communications, the BeiDou satellite system's communication capabilities can also be utilized for forwarding remote control commands when mobile cellular signals are weak.

[0145] Specifically, according to an embodiment of the present invention, the remote control device 500 for the digital currency wallet further includes a splitting module, which, after the step of encoding the remote control command according to the BeiDou message protocol to obtain the target message, is used for:

[0146] The remote control commands are encoded according to the BeiDou message protocol to obtain the message;

[0147] The message is split according to the message transmission capability of the BeiDou satellite system to obtain the target message.

[0148] According to embodiments of the present invention, the single communication capability (i.e., the payload of a single transmitted message and the corresponding time interval) of the BeiDou satellite system varies depending on the radiation range of the transmitted / sent information. If the length of the message determined after encoding the remote control command exceeds the single message transmission capability of the BeiDou satellite system, the message can be split into multiple short messages (i.e., target messages).

[0149] The Beidou Satellite 503 is used to forward target messages to the target digital currency wallet terminal based on the wallet number, so that the target digital currency wallet terminal can decode the target message to obtain remote control instructions, and realize remote control in offline mode according to the operation mode indicated in the remote control instructions.

[0150] Furthermore, according to an embodiment of the present invention, the remote control command also indicates the BeiDou communication module number corresponding to the target digital currency wallet terminal; the aforementioned BeiDou satellite 503 is also used for:

[0151] Based on the BeiDou communication module number and wallet number, the target message is forwarded to the target digital currency wallet terminal; the number of the target digital currency wallet terminals can be one or more.

[0152] Optionally, according to an embodiment of the present invention, a remote control command in the form of a message is sent to the Beidou communication module of the target digital currency wallet according to the Beidou communication module number and the wallet number, so that the Beidou communication module can decode the remote control command in the form of a message, thereby enabling the target digital currency wallet to decrypt and verify the signature of the corresponding remote control command after decoding, and realize remote control in offline state or under weak signal conditions according to the operation mode in the remote control command.

[0153] The above settings enable remote control of the digital currency wallet terminal even when it is offline or when the mobile cellular signal is weak (in which case the signal is easily interfered with), and ensure the effectiveness of the remote control.

[0154] According to the technical solution of this invention, by receiving remote control instructions sent by a digital currency platform, wherein the remote control instructions indicate the wallet number and operation mode corresponding to the target digital currency wallet terminal; encoding the remote control instructions according to the BeiDou message protocol to obtain a target message; and forwarding the target message to the target digital currency wallet terminal according to the wallet number, the target digital currency wallet terminal decodes the target message to obtain the remote control instructions and realizes remote control in offline mode according to the operation mode indicated in the remote control instructions. Therefore, this overcomes the technical problem in existing methods where it is difficult to effectively remotely control digital currency wallets in offline mode, resulting in low security and poor remote control performance. Furthermore, in offline mode, the remote control instructions generated by the digital currency platform are sent to the digital currency wallet terminal through the BeiDou satellite system to realize remote control of the offline digital currency wallet, significantly improving the security of the digital currency wallet terminal, enhancing the remote control effect, and improving the anti-interference capability of the forwarded information.

[0155] Figure 6 This is a schematic diagram of the main modules of the remote control device for a digital currency wallet provided in the sixth embodiment of the present invention; as shown. Figure 6 As shown, the remote control device 600 for a digital currency wallet provided in this embodiment of the invention is installed on the digital currency wallet terminal and mainly includes:

[0156] The message receiving module 601 is used to receive target messages forwarded by the BeiDou satellite system.

[0157] Specifically, according to an embodiment of the present invention, for a target message forwarded by the BeiDou satellite system, the BeiDou communication module (corresponding to the BeiDou communication module number of the target digital currency wallet terminal indicated in the remote control command) installed in the target digital currency wallet terminal receives the target message, so that the subsequent BeiDou communication module decodes the target message to obtain the remote control command.

[0158] The decoding module 602 is used to decode the target message to obtain the remote control command; wherein the remote control command indicates the operation mode of the target digital currency wallet terminal.

[0159] Optionally, according to an embodiment of the present invention, if the target message includes multiple short messages, the decoding module 602 is further configured to:

[0160] The remote control commands are obtained by combining the decoded portions of multiple short messages.

[0161] Furthermore, according to an embodiment of the present invention, the remote control device 600 for the digital currency wallet further includes a decryption processing module, which, if the remote control command obtained after decoding undergoes encryption and signature processing by the digital currency platform, is used for:

[0162] Decrypt the remote control commands;

[0163] Verify the signature corresponding to the decrypted remote control command.

[0164] According to an embodiment of the present invention, the encrypted remote control command can be decrypted according to a preset key (this is only an example, and any other existing encryption method can also be used); at the same time, the digital currency wallet terminal that receives the remote control command verifies the signature to ensure the legitimacy and trustworthiness of the remote control command, further guaranteeing the effectiveness of the remote control.

[0165] The remote control module 603 is used to perform corresponding operations according to the operation mode in order to realize remote control in offline mode.

[0166] Specifically, according to embodiments of the present invention, the aforementioned remote control instruction includes a transaction restriction instruction, which causes the target digital currency wallet terminal that receives the transaction restriction instruction to stop offline transactions. That is, when the remote control triggering condition includes "the risk level corresponding to the digital currency platform and / or any digital currency wallet terminal exceeds the risk level threshold", the target digital currency wallet terminal locks the wallet terminal after receiving the transaction restriction instruction, and can temporarily stop transactions.

[0167] Optionally, according to embodiments of the present invention, the remote control instruction may further include an updated list of risky wallet IDs. When the remote control triggering condition includes "the list of risky wallet IDs stored in any digital currency wallet terminal is inconsistent with the list of risky wallet IDs stored in the digital currency platform," the target digital currency wallet terminal, upon receiving the remote digital instruction, determines whether the counterparty's wallet ID belongs to the updated list of risky wallet IDs. If it does, meaning the counterparty's digital currency wallet is a risky digital currency wallet, the transaction is suspended; if it does not, meaning the counterparty's digital currency wallet is not a risky digital currency wallet, the transaction can continue. Through the above settings, remote control of the user's digital currency wallet terminal is possible even in situations with poor mobile cellular communication signals, especially offline, thus ensuring the security of the user's digital currency wallet assets.

[0168] According to the technical solution of this embodiment of the invention, by receiving the target message forwarded by the BeiDou satellite system, decoding the target message to obtain a remote control command, wherein the remote control command indicates the operation mode corresponding to the target digital currency wallet terminal, and performing corresponding operations according to the operation mode to achieve remote control in offline mode, the technical means overcome the technical problem in the existing method that it is difficult to effectively remotely control the digital currency wallet in offline mode, resulting in a low security level and poor remote control effect of the digital currency wallet. Furthermore, in offline mode, the remote control command generated by the digital currency platform is sent to the digital currency wallet terminal through the BeiDou satellite system to achieve remote control of the digital currency wallet in offline mode, thereby significantly improving the security level of the digital currency wallet terminal, enhancing the remote control effect, and improving the anti-interference capability of the forwarded information.

[0169] Figure 7 This is a schematic diagram of the main modules of the remote control system for a digital currency wallet provided according to an embodiment of the present invention; as shown. Figure 7 As shown, the remote control system 700 for a digital currency wallet provided in this embodiment of the invention mainly includes:

[0170] The digital currency platform 400 is used to set remote control trigger conditions according to business security requirements. When the remote control trigger conditions are met, a remote control command is generated and sent to the Beidou satellite system. The remote control command indicates the wallet number and operation method corresponding to the target digital currency wallet terminal.

[0171] Specifically, according to an embodiment of the present invention, the wallet number corresponding to the target digital currency wallet terminal is determined based on the remote control triggering conditions met; the remote control triggering conditions include one or more of the following:

[0172] The risk level of the digital currency platform and / or any digital currency wallet terminal exceeds the risk level threshold.

[0173] The list of risky wallet IDs stored in any digital currency wallet terminal is inconsistent with the list of risky wallet IDs stored in the digital currency platform.

[0174] According to embodiments of the present invention, the risk level threshold is set according to the actual situation, and the risks corresponding to digital currency platforms or digital currency wallet terminals mainly refer to things such as network attacks.

[0175] With the above settings, a remote control command is generated when the remote control trigger conditions are met. The remote control command is then sent as a message to the corresponding digital currency wallet terminal (i.e., the target digital currency wallet terminal) via the BeiDou satellite system. This ensures that even if the digital currency wallet terminal is offline or the current mobile cellular communication signal is poor (in which case the signal is easily interfered with), remote control of the digital currency wallet terminal can be achieved, and the remote control effect can be guaranteed.

[0176] Exemplarily, according to an embodiment of the present invention, after the step of generating remote control instructions, the digital currency platform 400 is further configured to:

[0177] Encrypt remote control commands;

[0178] Sign the encrypted remote control commands.

[0179] According to an embodiment of the present invention, the generated remote control command can be encrypted according to a preset key (this is only an example, and any other existing encryption method can also be used) to prevent the remote control command from being tampered with. At the same time, signing the remote control command can be decided whether to execute it according to the actual situation. It is easy to understand that signing the remote control command helps the digital currency wallet terminal that subsequently receives the remote control command to verify the signature to ensure the legitimacy and credibility of the remote control command, and further protect the remote control effect.

[0180] The BeiDou Satellite System 500 is used to receive remote control commands sent by digital currency platforms; it encodes the remote control commands according to the BeiDou message protocol to obtain the target message; and it forwards the target message to the offline target digital currency wallet terminal according to the wallet number.

[0181] Specifically, according to an embodiment of the present invention, after the above-described step of encoding the remote control command according to the BeiDou message protocol to obtain the target message, the BeiDou satellite system 500 is further used for:

[0182] The remote control commands are encoded according to the BeiDou message protocol to obtain the message;

[0183] The message is split according to the message transmission capability of the BeiDou satellite system to obtain the target message.

[0184] Furthermore, according to an embodiment of the present invention, the remote control command also indicates the BeiDou communication module number corresponding to the target digital currency wallet terminal; the aforementioned BeiDou satellite system 500 is also used for:

[0185] Based on the BeiDou communication module number and wallet number, the target message is forwarded to the target digital currency wallet terminal; the number of the target digital currency wallet terminals can be one or more.

[0186] Optionally, according to an embodiment of the present invention, a remote control command in the form of a message is sent to the Beidou communication module of the target digital currency wallet according to the Beidou communication module number and the wallet number, so that the Beidou communication module can decode the remote control command in the form of a message, thereby enabling the target digital currency wallet to decrypt and verify the signature of the corresponding remote control command after decoding, and realize remote control in offline state or under weak signal conditions according to the operation mode in the remote control command.

[0187] The above settings enable remote control of the digital currency wallet terminal even when it is offline or when the mobile cellular signal is weak (in which case the signal is easily interfered with), and ensure the effectiveness of the remote control.

[0188] The digital currency wallet terminal 600 is used to receive target messages forwarded by the BeiDou satellite system; decode the target messages to obtain remote control instructions; and perform corresponding operations according to the operation methods indicated by the remote control instructions to achieve remote control in offline mode.

[0189] Optionally, according to an embodiment of the present invention, if the target message includes multiple short messages, the digital currency wallet terminal 600 is further configured to:

[0190] The remote control commands are obtained by combining the decoded portions of multiple short messages.

[0191] Furthermore, according to an embodiment of the present invention, if the decoded remote control command undergoes encryption and signature processing by the digital currency platform, the aforementioned digital currency wallet terminal 600 is further used for:

[0192] Decrypt the remote control commands;

[0193] Verify the signature corresponding to the decrypted remote control command.

[0194] According to an embodiment of the present invention, the encrypted remote control command can be decrypted according to a preset key (this is only an example, and any other existing encryption method can also be used); at the same time, the digital currency wallet terminal that receives the remote control command verifies the signature to ensure the legitimacy and trustworthiness of the remote control command, further guaranteeing the effectiveness of the remote control.

[0195] According to the technical solution of this embodiment of the invention, a digital currency platform is used to set remote control trigger conditions according to business security requirements. When the remote control trigger conditions are met, a remote control command is generated; the remote control command is sent to the BeiDou satellite system; wherein, the remote control command indicates the wallet number corresponding to the target digital currency wallet terminal and the operation method; the BeiDou satellite system is used to receive the remote control command sent by the digital currency platform; the remote control command is encoded according to the BeiDou message protocol to obtain a target message; the target message is forwarded to the offline target digital currency wallet terminal according to the wallet number; the digital currency wallet terminal is used to receive the target message forwarded by the BeiDou satellite system; and the target message is processed... The system decodes the data to obtain remote control commands; it then performs corresponding operations according to the instructions in these commands, thus achieving remote control even in offline mode. This overcomes the technical problem in existing methods where effective remote control of offline digital currency wallets is difficult, resulting in low security and poor remote control performance. Furthermore, in offline mode, the system uses the BeiDou satellite system to send remote control commands generated by the digital currency platform to the digital currency wallet terminal, thereby achieving remote control of the offline digital currency wallet. This significantly improves the security of the digital currency wallet terminal, enhances the remote control effect, and strengthens the anti-interference capability of the forwarded information.
