Detailed Implementation

[0018] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" or "having" and any variations thereof are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0019] The first aspect of this invention provides an iOS virtual location method based on Bluetooth relay, aiming to provide iOS devices with a secure, covert, and low-cost virtual location solution by cloudifying physical Bluetooth hardware resources. See [link to relevant documentation]. Figure 1The iOS virtual location method based on Bluetooth relay includes: S100: The client sends a hardware allocation request to the relay authentication server. In this invention, the client can be installed and run as an application on a personal computer or smart device (such as an Android phone) with Bluetooth functionality. Its main functions include providing a user interface for inputting target latitude and longitude, managing local Bluetooth communication with the target mobile terminal (such as an iOS device), and conducting secure network communication with the relay authentication server.

[0020] The relay authentication server serves as a backend service system deployed in the cloud. Its core functions include: managing a hardware resource pool consisting of multiple Bluetooth MFi hardware modules, processing client requests and managing sessions, and securely forwarding authentication and location data as a data relay. The Bluetooth MFi hardware modules can be connected to the relay authentication server via USB or other wired methods. Each module integrates Bluetooth radio frequency functionality and a coprocessor or chip capable of processing specific authentication protocols (such as Apple's iAP2 protocol). The Bluetooth MFi hardware module is the physical anchor point for establishing a trusted connection with the target mobile terminal.

[0021] In an exemplary implementation scenario of step S100, the specific process may be that when a user needs to modify the location on the target mobile terminal (e.g., an iPhone), the user first launches a client application on their personal computer, and the client initiates a hardware allocation request to the relay authentication server through security protocols such as HTTPS.

[0022] S200, In response to the hardware allocation request, the relay authentication server selects an idle Bluetooth MFi hardware module from the multiple Bluetooth MFi hardware modules it manages, and returns the Bluetooth information of the idle Bluetooth MFi hardware module to the client.

[0023] In this invention, the relay authentication server maintains a status table of a hardware resource pool, recording the current status of all connected Bluetooth MFi hardware modules, such as idle, occupied, and faulty (i.e., the relay authentication server manages multiple hardware resource pools composed of the Bluetooth MFi hardware modules). Upon receiving a request from a client, the relay authentication server selects one of the idle Bluetooth MFi hardware modules for allocation according to a preset scheduling algorithm, such as round-robin or least-connection algorithm (i.e., selects the idle Bluetooth MFi hardware module from the hardware resource pool for allocation according to the round-robin or least-connection scheduling algorithm). This ensures load balancing and high system availability.

[0024] Next, the relay authentication server updates the status of the selected Bluetooth hardware module to occupied and returns key Bluetooth information of the idle MFi module, such as the Bluetooth device name and MAC address, to the client.

[0025] Furthermore, while allocating hardware, to ensure the security of subsequent communication, the relay authentication server creates a unique session identifier for this request and generates a temporary dynamic session key, such as a 256-bit random number, used only for this session. The relay authentication server sends this session identifier and dynamic session key, along with the allocated hardware information, to the client. The client stores this information locally for encryption of all subsequent communication with the server. Afterward, all data packets transmitted between the client and the server, especially sensitive authentication data, will be encrypted and decrypted using the dynamic session key via symmetric encryption algorithms such as AES-GCM, ensuring the confidentiality and integrity of data transmission (i.e., after responding to the hardware allocation request, the relay authentication server also generates a session identifier and dynamic session key for this session and sends the session identifier and dynamic session key, along with the Bluetooth information, to the client; subsequent data transmission between the client and the relay authentication server is encrypted and decrypted based on the dynamic session key).

[0026] S300. Based on the Bluetooth information, guide the iOS device to establish a local Bluetooth connection with the client. In this invention, after receiving the Bluetooth information returned by the server, the client guides the user to search for and perform standard Bluetooth pairing with the device corresponding to the Bluetooth name on the target mobile terminal (i.e., the iOS device). After successful pairing, the iOS device will initiate the accessory authentication process.

[0027] S400: The authentication data between the client and the idle Bluetooth MFi hardware module is relayed through the relay authentication server to complete the iAP2 authentication between the iOS device and the idle Bluetooth MFi hardware module. In this invention, the authentication process between the client and the idle Bluetooth MFi hardware module follows the iOS iAP2 (iPod Accessory Protocol 2) protocol specification. The specific relay process between the client, the relay authentication server, and the idle Bluetooth MFi hardware module can be as follows: S401, the client receives the first authentication data sent by the iOS device via the local Bluetooth connection. Specifically, during the transmission of uplink data in this invention, the iOS device sends an iAP2 protocol authentication data packet (i.e., the first authentication data is an iAP2 protocol authentication interaction data packet) to the client via the local Bluetooth connection.

[0028] S402. The client sends the first authentication data to the relay authentication server. Specifically, in this step of the present invention, after the client's Bluetooth module receives the authentication data packet, it does not parse it, but instead uses it as the raw payload, encrypts it using the dynamic session key obtained in the aforementioned step S200, attaches a session identifier, and sends it to the relay authentication server through the network.

[0029] S403. The relay authentication server forwards the first authentication data to the idle Bluetooth MFi hardware module for authentication processing and receives the second authentication data generated by the idle Bluetooth MFi hardware module. In this step of the invention, the relay authentication server finds the corresponding session and key based on the session identifier, decrypts the data packet, and obtains the original first authentication data. Then, the server sends this original data packet unchanged to the Bluetooth MFi hardware module connected to it and assigned to the session through an interface such as USB-to-Serial. The coprocessor in the Bluetooth MFi hardware module processes the iAP2 request and generates a corresponding response data packet (i.e., the second authentication data). In this invention, the second authentication data is also an authentication interaction data packet of the iAP2 protocol, specifically an AuthenticationCertificate data packet containing an authentication certificate. Then, the Bluetooth MFi hardware module transmits the second authentication data back to the relay authentication server, which encrypts it again using the dynamic session key and transmits it back to the client via the network.

[0030] S404. The client receives the second authentication data returned by the relay authentication server and sends the second authentication data to the iOS device via the local Bluetooth connection. In this step of the present invention, after the client receives the encrypted data and decrypts it to obtain the original second authentication data, it will immediately send the second authentication data to the target mobile terminal via the local Bluetooth connection. Specifically, the process of steps S401 to S404 of the present invention will be repeated several times according to the handshake process of the iAP2 protocol until the iOS device completes the authentication of the remote Bluetooth MFi hardware module. After the above process, the present invention can establish a virtual trusted communication link (LocationInformation channel defined by the iAP2 protocol) from the iOS device through the client and the relay authentication server, and finally to the Bluetooth MFi hardware module.

[0031] S500: After the iAP2 authentication process is completed, virtual location data is generated through the client and sent to the iOS device via the local Bluetooth connection to modify the system location of the iOS device through synchronous location.

[0032] In this invention, after authentication is completed, the client's user interface allows the user to input or select a target latitude and longitude. The client program will construct a virtual positioning data message conforming to the NMEA 0183 standard based on the input. Specifically, it will generate statements in at least two formats: GPGGA (Global Positioning System Positioning Data) and GPRMC (Recommended Minimum Positioning Information). That is, the virtual positioning data is a message conforming to the NMEA 0183 standard, and the message includes GPGGA format data and GPRMC format data.

[0033] Furthermore, in order to avoid unnatural shifts in location on the map, in an optional embodiment of the first aspect of the present invention, the iOS virtual location method based on Bluetooth relay further includes: when the target virtual location changes, generating a series of intermediate location data from the current location to the target virtual location through a location smoothing transition algorithm, and sending them sequentially to the iOS device to achieve a smooth change in location.

[0034] Specifically, in this invention, when a user sets a new target location, the location smooth transition algorithm calculates a series of intermediate coordinate points between the current location and the target location within the client. Within 1-3 seconds, it sequentially generates and sends NMEA messages for these intermediate points at a relatively high frequency (e.g., 4-10 times per second). This results in a smooth movement of the location pointer on the iOS device's map application, rather than an instantaneous jump. Finally, the client continuously sends the generated NMEA messages to the iOS device through the virtual trusted communication link established in step S404. Upon receiving this location data from trusted accessories, the iOS device's operating system uses it as system-level location information, thereby enabling the modification of the location for all applications (such as maps, social media, etc.).

[0035] To better illustrate the technical solution of this invention, in conjunction with... Figure 2 Taking the location synchronization of iOS devices via Apple's iAP2 protocol as an example, an exemplary iOS virtual location process of the present invention can be as follows: Step 1: The server establishes a Bluetooth relay service by physically connecting the Bluetooth hardware. Multiple hardware devices are deployed on the server to ensure that multiple users can access the service simultaneously and complete the processing at the same time. A timeout release process is set up for each user to ensure that the service is not maliciously occupied by users. The client initiates a Bluetooth device request, queues the Bluetooth service, and obtains the hardware information of the idle hardware on the server. If there is no idle device at this time, the client is told to queue and re-initiate the queuing request.

[0036] Step Two: After successfully queuing, the client obtains the specific hardware device information and pairs with the iOS device via Bluetooth. At this point, the client initiates a Bluetooth authentication request to the iOS device, carrying the hardware device information. After receiving a response from the iOS device, the client encrypts the response data using AES and transmits it to the server. The server decrypts the data and then sends it to the actually connected hardware device via Bluetooth. Once the hardware device is successfully authenticated, it returns the data to the client through the server (the data also needs to be AES encrypted and decrypted). The client then organizes the data and sends it to the iOS device. At this point, the iOS device has essentially authenticated the MFI protocol of the hardware connected to the server, and can perform relevant data exchanges.

[0037] Step 3: After the client receives the authentication data from the iOS device, the iOS device is now ready to send the synchronization location command. At this point, the client can input the latitude and longitude of the specific location. This latitude and longitude data will be packaged in GPGGA and GPRMC formats and sent to the iOS device via the BLE Bluetooth protocol. After receiving the command and verifying the correct authentication data, the iOS device will synchronize with the system's location module, confirming the map location synchronization. The client maintains a location update service of 4 times per second to ensure the stability of the modification. Using the virtual location scheme of this invention, after the iOS user modifies the location, there is virtually no detection trace. This allows for reasonable location modification, and the PC client supports multiple devices connecting simultaneously for modification, providing users with a more secure simulated location modification test.

[0038] See Figure 3 The second aspect of the present invention provides an iOS virtual positioning system based on Bluetooth relay, the iOS virtual positioning system based on Bluetooth relay includes a client 10, a relay authentication server 20 and a plurality of Bluetooth MFi hardware modules 30 connected to the relay authentication server.

[0039] In an optional embodiment of the second aspect of the present invention, the relay authentication server is further configured to generate a session identifier and a dynamic session key for the current session after responding to the hardware allocation request, and send the session identifier and the dynamic session key together with the Bluetooth information to the client; so that subsequent data transmission between the client and the relay authentication server is encrypted and decrypted based on the dynamic session key.
