[0045] To make the objectives, technical solutions and advantages of the present invention more clear and definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0046] It should be noted that if there are directional indications (such as up, down, left, right, front, back, etc.) involved in the embodiments of the present invention, such directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, the directional indications will also change accordingly.

[0047] An auxiliary recovery system provided to enable users to quickly find their mobile phones after the mobile phone is lost or stolen, providing useful information, improving the probability and efficiency of retrieving the mobile phone; in addition, it can deter thieves, reduce the number of illegal mobile phone theft incidents, and reduce the property losses of users.

[0048] Existing methods for retrieving mobile phones:

[0049] 1) Through the Find My Phone service: For example, Find My iPhone for certain fruit devices, Find My Device for the device, then you can log in to the specified account or Apple ID on another device, and then access the "Find My" website or application, and track and lock your device through the positioning function. After locking, you can also erase the data to protect personal information security.

[0050] 2) Through remote control applications: Many smartphones have pre-installed remote control applications, such as RemoteLock for Android, Lost iPhone Finder for iOS, etc. These applications allow users to send instructions after the device is lost, such as displaying a specific message, taking a photo, or locking the screen.

[0051] 3) Through GPS tracking: Ensure that the user's device has the GPS function enabled and still has power when it is lost. In this way, even if the mobile phone is turned off or muted, you can track its approximate location through the network service.

[0052] 4) Through social media and public announcements: Use social media platforms to post information about finding the mobile phone, describe the appearance of the lost mobile phone and the location of the last use. Maybe someone will provide clues. At the same time, this information can be broadcast to surrounding friends and the community. If you cannot retrieve the mobile phone after trying the above methods, report the theft to the police; by providing as much information as possible, such as the mobile phone model, serial number, and the date and time of the last use, this helps the police conduct the investigation.

[0053] However, the above existing methods for retrieving mobile phones have the following technical drawbacks:

[0054] 1) Over-reliance on technology: Many technologies for retrieving lost mobile phones rely on functions built into the device itself, such as GPS, network connection, remote control applications, or the "Find My Device" service. If the device does not have these functions, or if it cannot access the network after being lost, the likelihood of retrieval will be greatly reduced.

[0055] 2) Complicated operation: Even for devices that support the retrieval function, the complexity of the operation process may prevent users from taking prompt and effective actions in emergency situations. For example, factors such as forgetting account passwords, cumbersome login processes, or being unfriendly to non-professional users may affect the actual operation efficiency.

[0056] 3) Low positioning accuracy: Although modern technologies can provide relatively accurate location information, in some complex or remote areas, the positioning accuracy may be affected, thus affecting the specific location of the device search.

[0057] To solve the above technical problems, the embodiments of the present invention provide an auxiliary processing method for retrieving a lost mobile terminal. The present invention realizes the retrieval of a lost mobile phone through remote activation, and the retrieval methods include more functions such as GPS positioning, taking pictures, recording videos, making calls, file transmission, etc., which can greatly increase the probability of retrieving a lost mobile phone. Moreover, the present invention is simple, intelligent, and convenient to implement. Just log in to APK1 to send function commands to the lost mobile phone to achieve remote operation.

[0058] Exemplary method

[0059] As Figure 1 shown, an auxiliary processing method for retrieving a lost mobile terminal according to Embodiment 1 of the present invention includes the following steps:

[0060] Step S100: Install the first specified application APK1 on the user's other terminal in advance, and log in through real-name authentication or face recognition verification; and install the second specified application APK2 on the user's mobile terminal in advance, bind and authorize it with the user's SIM card or the mobile terminal SN number, and log in to the second specified application APK2 through real-name authentication or face recognition authentication of the same user;

[0061] In this embodiment, the user's mobile terminal may be the user's mobile phone. The embodiments of the present invention provide a method for quickly retrieving a lost user's mobile phone. The user's other terminal may be a user's home computer, tablet, or other terminals.

[0062] The present invention realizes remote task command issuance through APK, and combines with the operator to realize remote data network activation, ultimately realizing remote control of the lost mobile phone to improve the retrieval rate of the lost mobile phone.

[0063] In the embodiments of the present invention, the first specified application APK1 is pre-installed on other terminals of the user: The user installs APK1 on other devices (such as a computer or a tablet) and performs real-name authentication or face recognition login verification to ensure the authenticity of the identity.

[0064] The present invention also pre-installs the second specified application APK2 on the user's mobile terminal (such as a mobile phone): On the user's mobile phone, APK2 also needs to be installed and bound to ensure that only this device can access specific functions.

[0065] In the embodiments of the present invention, APK1 can be logged in on the user's computer or other electronic products by means of real-name authentication or face recognition; APK2 can be bound to the user's mobile phone SIM card, mobile phone SN number or other methods for user authorization, and APK2 needs to be logged in before the mobile phone is lost.

[0066] The APK in the embodiments of the present invention represents a file format used to distribute and install application programs in the user terminal operating system. That is, the APK of the present invention is a compressed file containing all the necessary components (such as code, resource files, manifest files, certificates, etc.) of a specified application program. The user can install the application on their terminal device by downloading and installing the APK file.

[0067] The main structure and content of the APK in the embodiments of the present invention may include:

[0068] Compiled code (.dex file): All application program codes are compiled into the Dalvik Executable format so that the user operating system can run.

[0069] Application program resources: This includes all necessary images, strings, layout files, etc., which help define the user interface and experience of the application.

[0070] A core configuration file that declares the components of the application (such as activities, services, broadcast receivers, etc.), the permissions used, and device requirements, etc.

[0071] META-INF directory: Contains certificates and manifest files for verifying the integrity and identity of the APK.

[0072] The roles of the APKs in the embodiments of the present invention, the two APKs (APK1 and APK2) are respectively:

[0073] The first specified application APK1: is a main application program used for functions such as authentication, user management, sending instructions, etc., to ensure that the user can access and control their lost mobile phone through other devices.

[0074] Second Specified Application APK2: It is an application specifically designed to be installed on the user's mobile terminal, responsible for receiving instructions from APK1 and executing them, such as positioning, taking pictures, or data backhaul, etc.

[0075] The benefits of the present invention through APKs include: Convenience: Users can easily download and install applications, and can complete it on the device just by using the APK file. Flexibility: Developers can directly provide applications by distributing APK files, without relying on the app store, which is convenient for specific users or test groups. Update and maintenance: Developers can simply upgrade the existing APK, and users can obtain the latest version of the application just by downloading the new APK file.

[0076] Step S200: When the user's mobile terminal is lost, the first specified application APK1 on other terminals logged in through real-name authentication or face recognition authentication of the same user sends a request to the operator server; control the operator server to remotely turn on the data network of the lost user mobile terminal through OTA, APN, eSIM remote configuration technology;

[0077] In the embodiment of this step, when the user's mobile terminal is lost, the user can send a request in the first specified application APK1, requesting the operator server to remotely enable the data network of the lost device through methods such as OTA (Over-the-Air technology), APN (Access Point Name), or eSIM (Embedded SIM card).

[0078] This process requires the user to confirm their identity again through real-name authentication or face recognition to prevent unauthorized access.

[0079] In this step, regarding controlling the operator server: This process requires the user's request to be sent to the server of the mobile network operator through the application (APK1). This usually involves an authentication mechanism to ensure that the request is legal and indeed comes from the owner of the device.

[0080] OTA (Over-the-Air technology): OTA is a wireless data transmission method. The present invention allows the operator to remotely send updates or perform configurations to the device without the need for manual operation by the user. This can authorize the user to remotely change the phone settings or install new software without physical contact.

[0081] APN (Access Point Name): APN is the gateway for the mobile device to connect to the Internet, defining the way for the device to access the external Internet through the mobile network. If the user's device originally had no Internet connection, the operator can remotely turn on the data network connection through APN configuration.

[0082] eSIM (Embedded SIM): An eSIM is a digital SIM card embedded in a device, as opposed to a traditional physical SIM card. This technology allows the remote activation or change of carrier services through software, enabling users to more easily reactivate the data network in case of device loss.

[0083] In the embodiments of the present invention, regarding remotely enabling the data network, specifically when the user's mobile terminal is lost, APK1 will first send a request to the carrier server through authentication. This request is to wake up the carrier's control over the lost device.

[0084] Then, after the carrier server receives the request, it will use OTA technology, APN configuration, or eSIM functionality to remotely activate the data network of the lost device, enabling it to reconnect to the network. This means that even if the user's mobile phone is not with them, through the request, the carrier server can still use these technical means to enable the data function.

[0085] In this way, the present invention enables users to quickly activate the device remotely through the carrier service, reducing manual operations and waiting time during the loss period. And this mechanism for remotely enabling the data network ensures that only legitimate users can request these operations, reducing the risk of malicious control. Also, users do not need to visit the carrier in person or go through complex procedures, and in this way, they can more conveniently obtain the network connection of the missing device to achieve functions such as positioning or monitoring.

[0086] Step S300: After the data network of the user's mobile terminal is enabled, control the first specified application APK1 on other terminals logged in through the real-name authentication or face recognition authentication of the same user to send GPS positioning, photographing, video recording, calling, and / or file backhaul instructions to the second specified application APK2 on the user's mobile terminal logged in through the real-name authentication or face recognition authentication of the same user;

[0087] In the embodiments of the present invention, once the device's data network is enabled, APK1 can send instructions to the lost mobile terminal (APK2 above), including: GPS positioning: obtaining the current location of the device; photographing, video recording: obtaining a view of the scene from the lost device; calling: making a call to a specific number through the lost device; file backhaul: obtaining important files or information stored on the mobile phone.

[0088] Specifically, in the embodiments of this step, when the data network of the user's lost mobile terminal is successfully activated, the device can connect to the Internet, allowing external access.

[0089] Other terminals for real-name authentication or face recognition authentication login of the same user: Specifically, the same user has logged in to APK1 through real-name authentication or face recognition authentication on their other devices (such as a computer or tablet), ensuring that the user's identity is verified and preventing unauthorized access.

[0090] Regarding controlling APK1 to send instructions to APK2: Specifically, in the present invention, APK1 will send instructions to APK2 on the lost mobile terminal. Since APK2 has been connected with the user's identity through real-name authentication or biometric recognition, it is safe to send instructions. The instructions sent include:

[0091] GPS positioning: Request APK2 to obtain the GPS location of the current device and feedback it to APK1 so that the user can know the specific location of the device.

[0092] Taking pictures: Send an instruction to make the camera of APK2 take pictures of the current environment to help the user understand the surrounding environment where the device is located.

[0093] Video recording: If necessary, instruct APK2 to perform video recording to obtain more on-site information.

[0094] Making calls: Can send instructions to record specific calls received or call a specific number (such as an emergency contact) to communicate with people who may find the device.

[0095] File backhaul: APK2 can backhaul some important files stored on the device to ensure that the user does not lose important data.

[0096] For example, if Zhang's mobile phone is lost in the park. He uses face recognition on the tablet through APK1 to confirm his identity. The following are the subsequent steps:

[0097] Enabling the network: After the APK1 on the user's other terminal requests the operator to successfully activate the data network of Zhang's mobile phone, Zhang sends instructions to APK2 on the mobile phone through APK1.

[0098] Obtaining the location: APK2 responds to the request and returns the current GPS coordinates of the mobile phone. Zhang finds that the mobile phone is in an area not far from him.

[0099] Taking pictures and video recording: APK2 uses the camera of the mobile phone to take pictures and send the pictures to Zhang's tablet. What Zhang sees is the surrounding environment and some passers-by.

[0100] Emergency call: APK2 dials an emergency contact number, and Zhang can communicate with passers-by in time and request assistance to retrieve the mobile phone.

[0101] Through such a process, Xiao Zhang can not only accurately locate the device, but also make judgments and confirmations based on on-site information, improving the success rate and security of retrieving lost devices.

[0102] In this invention, users can obtain the location and status of their lost devices in real time, increasing the chance of retrieving the devices. GPS positioning and photo-taking instructions provide users with necessary information to help them take prompt actions. And through real-name authentication or face recognition, it is ensured that only legitimate users can send instructions, thus guaranteeing the security of data and privacy and preventing malicious operations by third parties. Moreover, the photo-taking and video-recording functions not only help users confirm the location of the device, but also can show the environment around the device, helping users judge whether the device is in the possession of others and whether it is in a safe state.

[0103] Step S400: The first specified application APK1 on other terminals logged in through real-name authentication or face recognition authentication of the same user receives GPS positioning, photo-taking, video-recording, call, and / or file backhaul information sent by the second specified application APK2 on the user mobile terminal logged in through the same user account.

[0104] In the embodiment of this step, the APK1 on other terminals logged in through real-name authentication or face recognition authentication of the same user refers to that the user installs and logs in APK1 on other devices (such as a tablet or a computer), and ensures the legality of the identity through real-name authentication or face recognition. This identity verification ensures that only legitimate users can receive information about the lost device.

[0105] Regarding receiving the information sent by APK2: It refers to the feedback information sent by APK2 on the lost mobile terminal. These information can include:

[0106] GPS positioning: Users can know the exact geographical location of the lost mobile phone.

[0107] Photo-taking: APK2 can capture photos of the current environment and send them to APK1.

[0108] Video-recording: APK2 can record real-time videos around the mobile phone and transmit them to APK1.

[0109] Call: APK2 can record the audio information during a call or dial a specific rescue number.

[0110] File backhaul: APK2 can transmit files or important data stored on the lost device to APK1 to prevent data loss.

[0111] For example, if Xiaoli's mobile phone is lost in the mall. The following is the feedback information finally obtained through this step of the present invention:

[0112] Authentication: Xiaoli uses face recognition technology to verify her identity through APK1 installed on her tablet.

[0113] Information reception: APK1 receives information sent by APK2 from the lost mobile phone:

[0114] GPS positioning: Xiaoli finds that the mobile phone is exactly in a designated area of the shopping mall.

[0115] Taking pictures: The picture taken by APK2 shows that there is a passerby sitting next to the mobile phone, who may be the person who picked up the mobile phone.

[0116] Video recording: The video sent by APK2 shows the surrounding situation, and Xiaoli can judge whether the mobile phone is really occupied by others.

[0117] Call record: If APK2 records a call, Xiaoli can communicate with the person who picked up the mobile phone.

[0118] File transfer back: APK2 also transfers some important files of Xiaoli to prevent her data from being lost after the mobile phone is lost.

[0119] Through this process, Xiaoli can not only locate the mobile phone, but also view the surrounding environment and possible relevant information, so as to take effective measures to retrieve the mobile phone, improving the efficiency and success rate of retrieving the device.

[0120] It can be seen that the last step of the present invention is that APK1 receives information from the lost mobile phone APK2 on other terminals, including positioning data, photo / video files, call records and transferred file contents, ensuring that the user can obtain relevant information and status of the lost device.

[0121] The following further illustrates the method of the present invention with a specific application embodiment: In this specific embodiment, Xiaoming accidentally lost his smart phone. Then the following steps are performed using the present invention:

[0122] Corresponding to step S100: Xiaoming can install APK1 on his tablet and complete real-name verification. At the same time, he can install APK2 on his smart phone and bind it to Xiaoming's SIM card.

[0123] Corresponding to step S200: When the smart phone is accidentally lost, Xiaoming uses face recognition authentication through APK1 on the tablet to send a request to the operator server to re-enable the data network of the lost smart phone.

[0124] Corresponding to step S300: After the data network is turned on, APK1 sends an instruction to Xiaoming's smart phone APK2 to obtain the GPS positioning of the device, and at the same time triggers the mobile phone to take pictures of the current environment and record videos, and even can initiate a call to Xiaoming's friend to notify him.

[0125] Corresponding to step S400: The tablet of Xiaoming receives information from APK2, including the location of the lost mobile phone, the photos, videos and related files taken, so that Xiaoming can effectively understand the situation of the lost device and take corresponding actions.

[0126] Through such steps, Xiaoming can clearly and quickly retrieve his lost item, ensuring the security of his information to the greatest extent. And the present invention also has the following advantages:

[0127] 1) High security: The multi-factor authentication program ensures that only legitimate users can remotely access the lost device, which enhances security and reduces potential malicious operations.

[0128] 2) Remote control and monitoring: Users can retrieve the lost device through legal means, be able to locate and monitor in real time, increasing the effectiveness of anti-theft.

[0129] 3) Data protection: Users can remotely access and protect important data in the event of device loss, preventing the leakage of sensitive information.

[0130] 4) Improved user experience: This process simplifies the process of retrieving the device. Users no longer rely on the cumbersome steps of contacting customer service or enabling the retrieval function, improving user satisfaction.

[0131] In a further embodiment of the present invention, when the user's mobile terminal is lost, the first specified application APK1 of other terminals logged in through the real-name authentication or face recognition authentication of the same user sends a request to the operator server; the steps of controlling the operator server to remotely turn on the data network of the lost user mobile terminal through remote configuration technology include:

[0132] The first specified application APK1 of other terminals of the same user sends a request to the operator server through HTTP or HTTPS, WebSocket or a third-party SDK or API;

[0133] The first specified application APK1 of other terminals of the same user logs in and authorizes the operator server to remotely turn on the data network of the user mobile terminal through the real-name authentication or face recognition authentication of the same user by using OTA, APN, eSIM remote configuration technology.

[0134] In a further embodiment of the present invention, when the user's mobile terminal is lost, the first specified application APK1 of other terminals logged in through the real-name authentication or face recognition authentication of the same user sends a request to the operator server; the steps of controlling the operator server to remotely turn on the data network of the lost user mobile terminal through remote configuration technology include:

[0135] When the user's mobile terminal is lost, the first specified application APK1 on other terminals receives the user's operation instruction and logs in through real-name authentication or face recognition authentication of the same user;

[0136] When the login is successful and it is detected that the instruction to turn on the data network function is selected, an HTTPS request is sent to the operator server through the first specified application APK1 on the logged-in other terminal, including the user identity information and the SIM card number of the lost mobile phone; after controlling the operator server to verify the user identity, an instruction to turn on the data network is sent to the lost user mobile terminal through OTA technology, and the user mobile terminal is controlled to automatically turn on the data network.

[0137] That is, in the embodiment of the present invention, when the user's mobile terminal is lost, the user can use the specified application (APK1) on other terminals for identity authentication. This process includes real-name authentication (such as entering a username and password) or biometric technologies such as face recognition.

[0138] When the login is successful, the first specified application APK1 detects the instruction that the user selects to turn on the data network. Through APK1, an HTTPS request is sent to the operator server. This request contains the user's identity information and the SIM card number of the lost device, ensuring the legality and security of the request.

[0139] After the operator server verifies the user identity, it uses OTA (Over-the-Air) technology to send an instruction to the lost device to activate its data network function. At this time, the lost mobile terminal automatically turns on the data network.

[0140] For example, when user Li accidentally left his mobile phone in a coffee shop when going out. After realizing that the mobile phone was lost, he could use the method of the present invention to retrieve it. He could log in through his own tablet computer (APK1) using the method of the present invention and perform face recognition authentication. After the authentication passed, he selected to turn on the data network of the lost mobile phone. The application sent a relevant request to the operator's server, and soon after, the lost mobile phone reconnected to the data network, and Li was able to use the mobile phone location function to find the location of his mobile phone.

[0141] Doing so not only improves the success rate of retrieving the device, but also greatly facilitates the user's operation. And when the user's device is lost, he can quickly take action through other devices to activate the data network, which may make it easier to locate the lost device. And through real-name authentication or biometrics, it is ensured that only the user himself can perform such operations, reducing the risk of being exploited by malicious users. Moreover, turning on the data network may help the user track his device and increase the chance of retrieving the lost terminal.

[0142] In a further embodiment of the present invention, in the mobile terminal loss recovery assistance processing method, the steps of the first specified application APK1 of other terminals logged in through real-name authentication or face recognition authentication of the same user, and receiving GPS positioning, photographing, video recording, call and / or file backhaul information sent by the second specified application APK2 on the user mobile terminal logged in through the same user account further include:

[0143] The first specified application APK1 of other terminals logged in through real-name authentication or face recognition authentication of the same user receives a user operation instruction to select the location information acquisition function;

[0144] The first specified application APK1 sends a location request command to the second specified application APK2 through the WebSocket protocol;

[0145] After receiving the command, the second specified application APK2 calls the GPS module of the user mobile terminal to obtain the current location information, and sends the current location information back to the first specified application APK1 installed on other terminals of the user through the WebSocket;

[0146] After receiving the location information, the first specified application APK1 installed on other terminals of the user displays the specific location of the user mobile terminal on the map.

[0147] In a further embodiment of the present invention, the user can log in to the first application (APK1) on other devices (such as a tablet or another mobile phone), and use real-name authentication or face recognition for identity verification. After successful login, the user can select the location information acquisition function. At this time, APK1 sends a location request command to the second application (APK2) through the WebSocket protocol.

[0148] After receiving the request, the second application (APK2) installed on the lost mobile terminal activates the GPS module of the user's lost mobile phone to obtain the current location information. When the location data is obtained, the second application (APK2) will send the location information back to the first application (APK1) installed on other terminals of the user in real time through the WebSocket.

[0149] After receiving the location information on other terminals of the user, the first application (APK1) will display the specific location of the lost mobile terminal on the map, facilitating the user to locate and retrieve the device.

[0150] For example, when user Zhang's mobile phone is lost while he is out. He immediately uses his tablet (APK1), authenticates through face recognition, and selects the function to obtain location information. The tablet sends a location request command to Zhang's mobile phone (APK2) via WebSocket. After receiving the command, the mobile phone activates the GPS to obtain the current coordinates and quickly feeds back the location information to the tablet. Zhang can clearly see on the tablet that his mobile phone is located on a street next to a coffee shop. Using this information, he can quickly retrieve his mobile phone.

[0151] Through this process, the user not only saves time but also can easily locate the device, greatly reducing the annoyance caused by the loss of the mobile phone. Moreover, the present invention uses the WebSocket protocol to provide full-duplex communication, enabling the location request and response to be carried out in real time, which means that the user can quickly obtain the latest location information of the lost device. And with the real-time location information obtained through GPS, the success probability of retrieving the lost mobile phone is greatly increased, especially in the case where the device is moved by a moving vehicle or a person at different locations. And the function of displaying the location on the map allows the user to intuitively see the device location, improving the user's operation experience and enabling faster corresponding actions.

[0152] In a further embodiment of the present invention, in the mobile terminal loss recovery assistance processing method, the step of sending GPS positioning, photographing, video recording, calling, and / or file back transmission instructions to the second specified application APK2 on the user mobile terminal logged in through real-name authentication or face recognition authentication of the same user further includes:

[0153] Controlling to send back transmission instructions simultaneously through multiple available network channels including: 2G, 3G, 4G, Wi-Fi network channels;

[0154] In this step of the embodiment, after the user's mobile terminal is lost, multiple available network channels such as 2G, 3G, 4G, and Wi-Fi can be used simultaneously to send back transmission instructions to ensure that information can be quickly transmitted through the network. In this way, by using multiple network channels, the present invention can quickly switch to another available channel when any one network fails or has a weak signal, thus ensuring seamless transmission of the instructions.

[0155] When the user's mobile terminal is lost and the detected signal strength is lower than a predetermined value, control is performed to automatically switch to the next lower bandwidth and next higher fault tolerance communication mode to ensure instruction transmission;

[0156] In the embodiment of this step, if the signal strength of the terminal is detected to be lower than the predetermined value, the system will automatically switch to a communication mode with a lower bandwidth and a higher fault tolerance rate. This means that even in a poor network condition, instructions can still be stably transmitted. In this way, the present invention automatically switches to a communication mode with a lower bandwidth, enabling the system to work in various network environments and increasing its availability in remote or weak signal areas.

[0157] When the user's mobile terminal detects multiple illegal access attempts or enters a preset high-risk area, it automatically triggers the specified data erasure and system locking.

[0158] In the embodiment of this step, when multiple illegal access attempts are detected or the terminal enters a preset high-risk area (such as certain specific locations), the system will automatically trigger the data erasure and system locking functions to protect the security and privacy of user data. In this way, the automatic response mechanism of the present invention (such as data erasure and system locking) can effectively protect the privacy and sensitive information of users, preventing data from being illegally accessed or misused. This is particularly important for financial information, personal photos, and other important data. And by monitoring illegal access attempts and high-risk areas, the system of the present invention can actively defend against potential security threats, reduce the risk of data leakage, and improve the user's sense of security.
