The same reference numbers in different drawings represent the same or similar elements.
[0041] The scheme provided by the embodiments of the present application relates to an ESP32-based data security storage device, which is specifically described as follows:
[0042] In one embodiment, a data security storage device is provided, which comprises an ESP32 main module 110 and a USB interface 120, an RFID radio frequency identification module 140 and a storage module 130 connected with the ESP32 main module 110 respectively, and the ESP32 main module 110 comprises a WiFi module.
[0043] The above-mentioned various modules can be interconnected through the ESP32 main module 110, and the ESP32 main module 110 can optionally use ESP32-S3 as the main chip, integrates Bluetooth 5.0 and Wi-Fi module functions, and can realize interconnection and data transmission of the modules through its powerful function library.
[0044] The USB interface 120 conforms to the USB protocol of IEEE specification, is used for connecting with a computer device, and receives data transmitted by the computer device.
[0045] The USB interface 120 is connected to the computer device through the USB port 101, and has the performance of plug and play. The data security storage device 100 is compatible with the existing device USB2.0, USB3.0 and USB4.0 flash disk standards.
[0046] Referring to Figure 2 The data security storage device 100 is connected to the computer device through the USB port 101, and has the performance of plug and play. The data security storage device 100 is compatible with the existing device USB2.0, USB3.0 and USB4.0 flash disk standards.
[0047] The RFID radio frequency identification module 140 is used for user tag identification and reading of current user identification information.
[0048] Specifically, the RFID radio frequency identification module 140 detects whether there is a tag close to it. When the card reader detects the tag identification tag information, the user identification (UID) information is read. Optionally, the tag information can be stored. In actual application, the RFID radio frequency identification module 140 performs one or two times of tag identification in one-time data storage management. Through identity authentication and identification storage, human intervention operation is prevented, and data security is improved.
[0049] The storage module 130 is used for creating a corresponding target folder according to the current user identification information and timestamp information, and storing the data into the target folder.
[0050] Specifically, the RFID radio frequency identification module 140 completes one-time tag identification. The RFID radio frequency identification module 140 is specifically an RFID card reader. After reading the UID information, the storage module 130 can specifically use an SD card. In combination with the timestamp information in the ESP32-S3 time library, a target folder corresponding to the time and UID is created in the SD card. The data is stored into the target folder of the flash disk storage module 130. The SD card can provide local storage for saving log files, user data or important system information, etc. It supports various binary data formats such as PDF, MP4, Excel and text documents, etc.
[0051] The ESP32 main module 110 is used for receiving data from the computer device through the USB interface and storing the data into the storage module, then obtaining a confirmation instruction of the current user identification information, and uploading the source folder and source data in the storage module to the FTP file transfer server through the WiFi module according to the confirmation instruction.
[0052] The ESP32 main module 110 controls the storage of data received by the USB interface 120 to the storage module 130, and the data is stored in the corresponding target folder. The stored data and the target folder, the source folder and the source data of the storage module 130, can be uploaded. Here, the RFID radio frequency identification module 140 can perform a label identification check again. The RFID card reader performs a label check again and reads the UID information. The RFID has a read-write function and can be connected to the ESP32-S3 through the SPI interface. After the ESP32-S3 receives the confirmation information, the files in the SD card are uploaded to the directory of the FTP file transfer server through WIFI. The WIFI module allows the ESP32-S3 to connect to a wireless network, realize remote access to the Internet or a local area network, and then establish a connection with the FTP file transfer server configured in the laboratory. Then, the files on the SD card are uploaded through the FTP protocol.
[0053] In addition, the ESP32 main module is also used to actively delete the source folder and the source data in the storage module after uploading to the FTP file transfer server.
[0054] Specifically, the files stored in the SD card can be uploaded to the FTP file transfer server through the ESP32 main module to realize cloud storage and management. After successful uploading, the files in the SD card are deleted, and the file forwarding is completed. The files are uploaded to the cloud, and can be classified and managed in the cloud. Users can download the data themselves but cannot modify the data, ensuring the safety of the data and preventing the stored data from being tampered with.
[0055] The data security storage device of the embodiment disables personal data storage, reduces data loss, ensures system security, automatically sends data to the cloud for management, performs identity authentication and identification storage, prevents human intervention, prevents data tampering, and has high data security.

If the initialization fails, S318 can be executed to output information and prompt the user to take relevant operation failure information. After the file mounting is successful, the ESP32 main module performs S305 to connect to the WIFI and S306 to connect to the FTP, and automatically connects to the WIFI and the corresponding FTP file transfer server provided by the laboratory. Then, the RFID radio frequency identification module 140 performs user tag identification, the storage module 130 performs data storage, and the ESP32 main module performs time-limited file cloud uploading, and the like.
