Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Combine the following Figure 1-Figure 8 The present invention describes the confidential document circulation tracking method, device and system based on the national confidential information innovation system.

[0057] like Figure 1 As shown, in one embodiment, a method for tracking the circulation of confidential documents based on the national secret information creation system includes the following steps:

[0058] Step S100, reading and recording the RFID tag information of the confidential document.

[0084] It is convenient for the monitoring center to view the location of confidential documents, the identity information of the escort and the status of confidential documents in real time through the system interface, so as to realize real-time monitoring and tracking.

[0085] The following is a description of the confidential document circulation tracking device based on the national secret information creation system provided by the present invention. The confidential document circulation tracking device based on the national secret information creation system described below and the confidential document circulation tracking method based on the national secret information creation system described above can be referenced to each other.

[0086] like Figure 4 As shown, in one embodiment, a confidential document circulation tracking device based on the national confidential information innovation system includes a reading module 410, an acquisition module 420, an encryption module 430, an identification module 440 and a binding module 450.

[0087] The reading module 410 is used to read and record the RFID tag information of the confidential document.

[0088] The acquisition module 420 is used to acquire confidential document status information, which includes confidential document deposit, escort and retrieval status information.

[0089] The encryption module 430 is used to receive the location information of the confidential document and encrypt the location information of the confidential document.

[0090] The identification module 440 is used to identify the identity information of the escort or recipient.

[0091] The binding module 450 is used to bind the identity information of the escort or the recipient with the confidential information in response to the identity information of the escort or the recipient being correct.

[0092] In this embodiment, the location information of the confidential document is encrypted, specifically for:

[0093] The location information of the confidential document is encrypted based on a symmetric encryption algorithm or an asymmetric encryption algorithm.

[0094] In this embodiment, the location information of the confidential document is encrypted based on a symmetric encryption algorithm or an asymmetric encryption algorithm, specifically for:

[0095] Read the key and attach the key to the location information of the secret document;

[0096] receiving the encrypted location information of the secret document, and decrypting the location information of the secret document based on the same key;

[0097] Or, read the public key and attach the public key to the location information of the secret document;

[0098] Receiving encrypted confidential document location information;

[0099] The private key is read and the location information of the secret document is decrypted based on the private key.

[0100] In this embodiment, the location information of the confidential document is encrypted, and is also specifically used for:

[0101] Encrypt the location information of the secret document based on a secure hash algorithm and generate a first digital summary, where the first digital summary is a hash value of the location information of the secret document;

[0102] Reading a private key, and encrypting the first digital summary based on the private key to form a digital signature;

[0103] Send the original confidential document location information and digital signature to the recipient;

[0104] Read the public key and decrypt the digital signature based on the public key;

[0105] Encrypting the original confidential document location information to generate a second digital summary;

[0107] In this embodiment, the confidential document circulation tracking device based on the national confidential information innovation system also includes a sending module 460, and the sending module 460 is used to send the confidential document status information and the encrypted confidential document location information to the monitoring center in real time.

[0108] The confidential document circulation tracking device based on the national secret information innovation system can locate the position of confidential documents in real time by binding the identity information of the escort or recipient with the confidential document information, and encrypt the location information of the confidential documents. It can meet the needs of high security and high-precision positioning, and facilitate automatic tracking and recording of the entire life cycle of the generation, circulation, use, and clearance of confidential documents.

[0109] The existing confidential document tracking system is mainly based on RFID technology, but it has the following disadvantages:

[0110] 1. RFID systems are mainly used to identify and track items, but they cannot provide precise location information. The positioning accuracy is usually at the meter level or lower.

[0111] 2. RFID tag information is easily intercepted and counterfeited, lacks data encryption protection, and poses a security risk. For confidential documents, the administrator's data such as location information also needs to be kept confidential, and RFID cannot provide protection for this data.

[0112] 3. Due to the lack of high-precision positioning and real-time data transmission functions, it is difficult for RFID systems to achieve real-time monitoring and tracking of items.

[0113] 4. It is inconvenient to track and manage confidential documents in different states (such as when stored in a movable safe or carried by an escort).

[0114] Therefore, if Figure 5 , Figure 6 and Figure 7 As shown, in one embodiment, a confidential document circulation tracking system based on the national confidential information innovation system includes a movable safe 510, an RFID tag 520, a handheld device 530, a confidential document tracking module 540 and a confidential document tracking management module 550.

[0115] The movable safe 510 is used to store confidential documents during the circulation process.

[0116] The RFID tag 520 is attached to the confidential article and is used for item identification.

[0117] The handheld device 530 is used to realize the circulation of confidential documents.

[0118] The confidential document tracking module 540 is loaded in the handheld device 530 and the movable safe 510, and includes a national secret security chip 541, a wireless communication module 542, an RFID identification module 543, a positioning module 544 and an identity recognition module 545, and is used for tracking and reporting during the confidential document flow control process. The national secret security chip 541 is used to encrypt the location information of the confidential documents.

[0119] Among them, the national secret security chip 541 is a hardware device specially designed to protect data and communication security. The national secret security chip 541 provides physical protection for data by integrating multiple security functions and encryption algorithms to prevent unauthorized access, tampering and attacks. The national secret security chip 541 is a security chip that integrates national secret algorithms such as SM1 / SM2 / SM3 / SM4, and meets the requirements of the information innovation system.

[0120] The wireless communication module 542 is an NB-IoT module, a 5G communication module or a Lora module, wherein NB-IoT (NarrowBand Internet of Things) is a low-power wide area network (LPWAN) communication technology designed specifically for Internet of Things (IoT) devices. NB-IoT technology has significant advantages in spectrum efficiency, coverage, number of connections and power consumption, and is very suitable for IoT applications that require low data transmission rates and long battery life. Lora (Long Range Radio) can transmit farther than other wireless methods under the same power consumption conditions, achieving the unity of low power consumption and long distance.

[0121] RFID (Radio Frequency Identification) uses radio waves for contactless communication to identify targets or obtain data. RFID technology has the advantages of non-contact, fast, multi-tag simultaneous recognition, and automated management. It is widely used in logistics management, asset tracking, access control and other fields.

[0122] It should be noted that the positioning module 544 is a Beidou positioning module, which can achieve high-precision positioning and real-time tracking of confidential documents.

[0123] The identity recognition module 545 can recognize face information, iris detection information or fingerprint information.

[0124] The confidential document tracking management module 550 receives, decrypts, and stores the data during the confidential document circulation process.

[0125] The workflow of the confidential document circulation tracking system based on the national secret information creation system is as follows:

[0126] 1. Storage of confidential documents: The confidential documents are placed in the portable safe 510 . The RFID identification module 543 in the portable safe 510 reads and records the RFID tag 520 information of the confidential documents. At the same time, the Beidou positioning module 544 of the portable safe 510 starts working to record the position of the portable safe 510 .

[0127] 2. Removal and binding of confidential documents:

[0128] When it is necessary to take out confidential documents from the portable safe 510, the escort uses a handheld device 530 to scan the RFID tag 520 of the portable safe 510 to confirm his identity.

[0129] The escort takes the confidential document out of the movable safe 510 and scans the RFID tag 520 on the confidential document with a handheld device 530. The handheld device 530 records the information of the confidential document and binds it with the identity information of the escort.

[0130] The Beidou positioning module 544 of the handheld device 530 starts to work, recording and uploading the location information of the escort and the confidential documents in real time.

[0131] 3. Escort process:

[0132] During the escort process, the handheld device 530 transmits the location information and status information of the confidential document to the monitoring center in real time through the wireless communication module 542.

[0133] The monitoring center can view the location of confidential documents, the identity information of the escort and the status of confidential documents in real time through the system interface.

[0134] 4. Handover of confidential documents:

[0135] When the confidential document arrives at the destination, the escort will hand it over to the recipient, who will use a handheld device 530 to scan the RFID tag 520 of the confidential document to confirm the identity information of the confidential document.

[0136] The recipient puts the confidential document into the portable safe 510 at the destination, and the RFID identification module 543 of the portable safe 510 reads and records the information of the RFID tag 520 of the confidential document, thus completing the handover.

[0137] The confidential document circulation tracking system based on the national secret information innovation system, on the one hand, realizes the seamless circulation management of confidential documents between the movable safe 510 and the escort by combining RFID technology, security chip technology based on national secrets, Beidou positioning technology, and NB-IoT technology. At the same time, by adopting the national secret security chip 541 to encrypt the location information of the confidential documents, it can protect the location information from being leaked during real-time tracking. On the other hand, the location is reported regularly through the handheld device 530, and the reporting operation can only be successful after the completion of biometric identification. This ensures the binding of people and devices, and then the binding of devices and confidential documents is realized through the confidential document tracking module 540, thereby realizing the binding of people and documents.
