[0004] This application provides a mobile storage device and its anti-loss system, which aims to avoid data leakage after the mobile storage device is lost.

[0012] The main control chip is electrically connected to both the memory and the read / write protection module; and

[0013] A communication antenna is electrically connected to the main control chip.

[0014] The memory or the main control chip stores the identification information of the mobile storage device. The communication antenna is used to broadcast a handshake signal containing the identification information to a mobile terminal outside the device, and to receive the control command sent by the mobile terminal after the mobile storage device establishes a communication connection with the mobile terminal based on the handshake signal.

[0031] The mobile storage device anti-loss system disclosed in this application involves the mobile storage device actively broadcasting a handshake signal containing unique identification information. When a mobile terminal enters the broadcast range, it can recognize the presence of the mobile storage device and receive the handshake signal. Subsequently, the mobile terminal can upload the identification information and its own location information to a server, and then communicate with the reporting terminal through the server to feed back the location information to the reporting terminal.

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] A portable storage device 100 is a device used to transfer, back up, or expand storage capacity between different devices, characterized by portability and high reliability. However, if a portable storage device 100 is accidentally lost, it can easily lead to the risk of data leakage, thereby affecting the user's information security.

[0045] In this application embodiment, the mobile storage device 100 includes, but is not limited to, USB flash drives, portable hard drives, and earphones with storage functions.

[0046] To address the issue of data leakage after the loss of the mobile storage device 100, please refer to the following: Figure 1 This application provides a mobile storage device anti-loss system, which includes a mobile storage device 100, a mobile terminal 200, a loss reporting terminal 300, and a server 400.

[0047] The reporting terminal 300 is the terminal device of the user who lost the mobile storage device 100. The reporting terminal 300 is communicatively connected to the server 400 and can send control commands to the server 400. In some embodiments, the reporting terminal 300 and the server 400 are connected via Wi-Fi, and signal and data transmission is achieved through this Wi-Fi connection. In some embodiments, the reporting terminal 300 and the mobile storage device 100 were already bound before the device was lost. The reporting terminal 300 can be a mobile phone, tablet, or smartwatch, etc.

[0048] The mobile storage device 100 internally includes a memory 20, an interaction module 30, and a read / write protection module 40. In this embodiment, the interaction module 30 is communicatively connected to an external mobile terminal 200 and can receive control commands sent by the mobile terminal 200. The read / write protection module 40 is electrically connected to both the memory 20 and the interaction module 30. After the interaction module 30 receives a control command from the mobile terminal 200 to disable the read / write function, the interaction module 30 can control the read / write protection module 40 to be enabled, thereby disabling the read / write function of the memory 20 to prevent the leakage of personal information.

[0049] In this embodiment, the interaction module 30 includes a main control chip 31 and a communication antenna 32, with the main control chip 31 electrically connected to the communication antenna 32. The main control chip 31 or the memory 20 stores identification information of the mobile storage device 100, wherein the identification information is unique. The communication antenna 32 is used to broadcast a handshake signal containing the identification information to the external mobile terminal 200. The mobile storage device 100 can establish a communication connection with the mobile terminal 200 based on the handshake signal. In this embodiment, the handshake signal refers to a series of control signals or messages exchanged between the two communicating parties (i.e., the near-field communication device 100 and the mobile terminal 200) before establishing a formal connection or starting data transmission, used to negotiate parameters, synchronize states, confirm the existence of the other party, establish trust, and ensure that both parties are ready.

[0050] Mobile terminal 200 communicates with server 400. In some embodiments, mobile terminal 200 and server 400 communicate via Wi-Fi, and signal and data transmission is achieved through Wi-Fi connection. In some embodiments, mobile terminal 200 receives a handshake signal sent by mobile storage device 100 via Bluetooth. After receiving the handshake signal, mobile terminal 200 can upload the identification information carried in the received handshake signal and its own location information (i.e., geographical location, which can be provided by the GPS (Global Positioning System) module of mobile terminal 200) to server 400. Mobile terminal 200 includes, but is not limited to, devices such as mobile phones, tablets, or smartwatches.

[0051] After receiving the identification information and location information, server 400 can match the corresponding reporting terminal 300 (i.e., a terminal device already bound to mobile storage device 100) based on the identification information and feed back the location information to the corresponding reporting terminal 300. This feedback can be achieved through methods such as app notifications, pop-up notifications, or SMS notifications. Furthermore, server 400 can also receive control commands sent by the reporting terminal 300. When a mobile terminal 200 with the same operating system as the lost mobile storage device 100 establishes a communication connection with the mobile storage device 100 based on a handshake signal, server 400 can forward the stored control commands to that mobile terminal 200. Notably, server 400 in this application utilizes cloud technology, i.e., a cloud server 400.

[0052] The mobile storage device anti-loss system of this application involves the mobile storage device 100 actively broadcasting a handshake signal containing unique identification information. When a mobile terminal 200 enters the broadcast range, it can recognize the presence of the mobile storage device 100 and receive the handshake signal. Subsequently, the mobile terminal 200 can upload the identification information and its own location information to the server 400, and then communicate with the reporting terminal 300 through the server 400 to feed back the location information to the reporting terminal 300. This system effectively improves the problem of the difficulty in finding the mobile storage device 100 after it is lost, provides a technical means for quickly locating the lost mobile storage device 100, and significantly improves the success rate of finding the lost mobile storage device 100.

[0053] Furthermore, the mobile storage device anti-loss system of this application also receives a control command to disable the read / write function sent by the reporting terminal 300 through the server 400, and sends the control command to the mobile terminal 200; then, the mobile terminal 200 forwards the control command to the mobile storage device 100. When the mobile storage device 100 receives the control command to disable the read / write function, it can disable the read / write function of the memory 20 through the read / write protection module 40 to prevent the leakage of personal information, maintain the security of personal information, and thus improve the security and reliability of the mobile storage device 100.

[0054] In some implementations, the main control chip 31 and the mobile terminal 200 run the same operating system. On the one hand, this reduces development difficulty and costs; on the other hand, it reduces compatibility issues and facilitates subsequent version updates, thereby improving convenience.

[0055] It should be noted that this application does not specifically limit the type of operating system, and those skilled in the art can choose flexibly according to the actual product situation. For example, both the main control chip 31 and the mobile terminal 200 run the Android operating system; or, both the main control chip 31 and the mobile terminal 200 run the iOS operating system; or, both the main control chip 31 and the mobile terminal 200 run the HarmonyOS operating system.

[0056] Please continue reading. Figure 1 The working process of the mobile storage device anti-loss system of this application is described.

[0057] Specifically, after the mobile storage device 100 is lost, it can actively broadcast a handshake signal carrying identification information. If a mobile terminal 200 running the same operating system as the lost mobile storage device 100 is nearby, the mobile terminal 200 can receive the handshake signal sent by the mobile storage device 100. After receiving the handshake signal, the mobile terminal 200 can upload the identification information carried in the received handshake signal and its own location information to the server 400. Subsequently, the server 400 matches the corresponding reporting terminal 300 based on the identification information and sends the location information back to the corresponding reporting terminal 300. The user of the lost mobile storage device 100 can retrieve the mobile storage device 100 by viewing the location information on the reporting terminal 300.

[0058] Furthermore, after discovering the loss of the mobile storage device 100, the user can operate the reporting terminal 300 to send control commands (including, but not limited to, commands to disable read / write functions and commands to enable alarm notifications) to the server 400. Upon receiving the control commands from the reporting terminal 300, the server 400 can store them. When a mobile terminal 200 with the same operating system as the lost mobile storage device 100 approaches it, the mobile terminal 200 can receive a handshake signal and establish a communication connection with the mobile storage device 100 based on the handshake signal. Subsequently, the server 400 can forward the stored control commands to the mobile terminal 200, which then sends the control commands to the main control chip 31 of the mobile storage device 100. Upon receiving the control commands, the main control chip 31 can control the corresponding components to take action.

[0059] Among them, the reporting terminal 300 and the mobile terminal 200 can be the same terminal device.

[0060] In the embodiments of this application, please refer to the following: Figure 1 The mobile storage device 100 of this application includes a housing 10, a memory 20, an interaction module 30, and a read / write protection module 40.

[0061] The housing 10 is the external structure of the mobile storage device 100, providing installation space for the internal components of the mobile storage device 100 and protecting the internal components. The housing 10 is usually made of plastic or metal materials, such as PVC (polyvinyl chloride) plastic or stainless steel. The housing 10 is usually rectangular and has good mechanical strength, corrosion resistance and portability.

[0062] The memory 20 is housed within the casing 10. The memory 20 is a core component that implements the basic functions (i.e., storage function) of the mobile storage device 100, used to store the user's personal information and various files. In some embodiments, when the mobile storage device 100 is a general-purpose storage device such as a USB flash drive or portable hard drive, the memory 20 can be used to store various types of files. In some embodiments, when the mobile storage device 100 is a specific storage device such as headphones with storage function, the memory 20 can be used to store audio files.

[0063] The interaction module 30, located within the housing 10, is the core module of the mobile storage device 100 used to enable information transmission and feedback between the user and the mobile terminal 200 or other devices. In this embodiment, the interaction module 30 is communicatively connected to the external mobile terminal 200 to receive control commands sent by the mobile terminal 200.

[0064] The read / write protection module 40 is housed within the casing 10. This module enables or disables the read / write function of the memory 20, enhancing the security of personal information stored in the memory 20. The read / write protection module 40 is electrically connected to both the interaction module 30 and the memory 20. Upon receiving a control command from the mobile terminal 200 to disable the read / write function, the interaction module 30 can control the read / write protection module 40 to activate, thereby disabling the read / write function of the memory 20 and preventing the leakage of personal information.

[0065] This application receives a control command to disable the read / write function sent by the reporting terminal 300 through the interaction module 30. After the interaction module 30 receives the control command to disable the read / write function, it controls the read / write protection module 40 to be turned on, thereby disabling the read / write function of the memory 20 to prevent the leakage of personal information, maintain the security of personal information, and thus improve the security and reliability of the mobile storage device 100.

[0066] In some implementations, see Figure 1The main control chip 31 includes a main control chip 31 and a communication antenna 32, which are electrically connected. The main control chip 31 stores the identification information of the mobile storage device 100, which is unique and includes, but is not limited to, the MAC address (Bluetooth address) of the mobile storage device 100. The communication antenna 32 is used to broadcast a handshake signal containing the identification information to the external mobile terminal 200.

[0067] In an alternative implementation, the identification information of the mobile storage device 100 can also be stored in the memory 20, and the identification information stored in the memory 20 can be retrieved when the communication antenna 32 broadcasts a handshake signal.

[0068] The mobile terminal 200 actively broadcasts a handshake signal containing unique identification information to the outside world via the communication antenna 32, enabling it to receive the handshake signal and upload the identification information and its own location information to the server 400 after receiving the handshake signal. By setting up an interaction module 30 in the mobile storage device 100, hardware support is provided for locating the lost mobile storage device 100, thereby helping to improve the difficulty of finding the lost mobile storage device 100.

[0069] In some embodiments, the main control chip 31 is a Bluetooth Low Energy (BLE) SOC (System on Chip) chip. A BLE SOC chip is a highly integrated chip with a built-in Bluetooth wireless communication module. It integrates a processor, communication radio frequency, memory, and peripheral interfaces, and is the core component for the mobile storage device 100 to achieve wireless communication and device control. This allows the near-field communication device 100 to complete data transmission, reception, processing, and control functions on a single chip, greatly improving the system's integration and reliability. Furthermore, the BLE SOC chip has advantages such as low power consumption, high integration, and small size. It can be housed inside the casing 10 without affecting the original appearance of the mobile storage device 100, which is beneficial for the compact design of the near-field communication device 100. It also allows the device to operate for extended periods without frequent charging, making it more convenient to use. It should be noted that this application does not specifically limit the type of the main control chip 21; those skilled in the art can flexibly adjust the type of the main control chip 21 according to actual product requirements.

[0070] In some implementations, see Figure 1 The interaction module 30 also includes a timer 33, which is electrically connected to the main control chip 31. The timer 33 provides a basic and stable clock signal for the operation of the main control chip 31, helping to maintain system stability and ensure the accuracy of signal transmission. The main control chip 31 can control the communication antenna 32 to periodically broadcast handshake signals based on the timing signal provided by the timer 33. This saves energy. The timer 33 includes, but is not limited to, a crystal oscillator.

[0071] In some implementations, see Figure 1 The interaction module 30 also includes a battery 34, which is electrically connected to the main control chip 31 and supplies power to the main control chip 31, providing power support for its operation and ensuring its stable operation. This application does not specifically limit the type of battery 34. Without affecting the original appearance of the mobile storage device 100, those skilled in the art can flexibly adjust the type of battery 34 according to actual product needs. For example, the battery 34 can be a button cell battery, etc.

[0072] In some implementations, see Figure 1 The interaction module 30 also includes an alarm 35, which is electrically connected to the main control chip 31 and is used to issue an alarm notification under the control of the main control chip 31. With this configuration, firstly, if the mobile storage device 100 is lost in a relatively hidden corner, issuing an alarm notification can help the lost user quickly locate and retrieve the mobile storage device 100; secondly, issuing an alarm notification can attract attention from the surrounding area, and when someone approaches the mobile storage device 100, if there is a mobile terminal 200 with the same operating system as the main control chip 31 nearby, the mobile storage device anti-loss system of this application can provide the lost user with the location information of the mobile storage device 100, facilitating its retrieval; thirdly, issuing an alarm notification can also deter unauthorized possessors to a certain extent.

[0073] Understandably, after discovering the loss of the mobile storage device 100, the user can operate the reporting terminal 300 to send a control command to the server 400 to activate the alarm notification. Upon receiving the control command, the server 400 can store it. When a mobile terminal 200 with the same operating system as the lost mobile storage device 100 approaches it, the mobile terminal 200 can receive a handshake signal from the mobile storage device 100 and establish a communication connection based on the handshake signal. Subsequently, the server 400 can forward the stored control command to the mobile terminal 200. The mobile terminal 200 can then send the control command to the main control chip 31 of the mobile storage device 100. Upon receiving the control command, the main control chip 31 can control the alarm 35 to issue an alarm notification.

[0074] It should be noted that this application does not specifically limit the type of alarm 35, and those skilled in the art can flexibly adjust the type of alarm 35 according to the actual product situation. For example, alarm 35 can be a buzzer, which can emit a buzzing sound under the control of main control chip 31; or alarm 35 can also be an indicator light, which can emit a flashing light under the control of main control chip 31; or, both a buzzer and an indicator light can be provided, which can emit a buzzing sound and / or flashing light under the control of main control chip 31.

[0075] In some implementations, see Figure 1 The mobile storage device 100 also includes a USB interface 50, which serves as a physical connection channel between the mobile storage device 100 and the external device 500. The USB interface 50 is disposed on the housing 10 and electrically connected to the memory 20. The USB interface 50 can be plugged into external devices 500 such as computers and smartphones to achieve electrical connection, thereby realizing the electrical connection between the mobile storage device 100 and the external device 500 for reading and writing data to the memory 20.

[0076] This application does not specifically limit the method of connecting the USB interface 50 to the external device 500. For example, when the mobile storage device 100 is a USB flash drive, the USB interface 50 can be directly plugged into the external device 500 to achieve an electrical connection, thereby reading and writing data to the storage device 20; or, when the mobile storage device 100 is a portable hard drive, the USB interface 50 can be indirectly connected to the external device 500 through a data cable to achieve an electrical connection, thereby reading and writing data to the storage device 20.

[0077] In some implementations, see Figure 1 The mobile storage device 100 also includes a voltage converter 60, which is a component that changes the input voltage level and outputs a voltage that meets the requirements of the target components. The voltage converter 60 is electrically connected to the USB interface 50, the main control chip 31 in the interaction module 30, and the memory 20. After the USB interface 50 is electrically connected to the external device 500, the external device 500 can input voltage into the mobile storage device 100 through the USB interface 50. The voltage converter 60 can convert the voltage supplied by the external device 500 into the voltage required by the memory 20 and the main control chip 31, thereby supplying power to the memory 20 and the main control chip 31. This configuration can provide the power support required for the memory 20 to perform read and write operations, ensuring that the memory 20 can operate normally and stably; at the same time, it can also supply power to the main control chip 31, reducing the burden on the battery 34 in supplying power to the main control chip 31 and extending the battery 34's lifespan to a certain extent.
