Description

Technical Field

[0001] The present disclosure belongs to the technical field of baggage processing, and in particular, relates to an improved system and method for generating and processing airport departure baggage tag data. Background Art

[0002] Baggage handling is becoming more and more important during passenger air travel, especially in recent years, the continuous expansion of airport passenger volume has put forward higher requirements for the efficiency and automation of airport baggage handling. Once the relevant information system fails, the baggage cannot be automatically handled, which will cause the entire airport departure process to stagnate or paralyze.

[0003] At present, the airport outbound baggage handling method is completed in accordance with the relevant standards of IATA (International Air Transport Association). Passengers go through the departure subsystem to check in and check in their baggage, and print the baggage tag in the IATA standard data format. At the same time, the departure subsystem generates a standard BSM (Baggage Source Message) message corresponding to the baggage and transmits it to the baggage handling subsystem through the interface module. The baggage handling subsystem parses the baggage tag number and flight information in the BSM message, associates and stores this information in the system. When the baggage is transmitted to the corresponding processing node (such as a conveyor belt sorting node), the optical device or RFID identification device on the node automatically scans and identifies the baggage tag barcode or RFID chip, reads the baggage number, and matches it with the flight association information stored in the baggage handling subsystem to complete the baggage "authentication", identify the flight location information (such as the baggage sorting port) to which the baggage belongs, and finally automatically transports the baggage to the location through the conveyor device to achieve automatic processing.

[0004] The disadvantage of this standard method is that the automatic baggage handling process is highly dependent on the timely generation and reception of BSM messages. If the message interface module fails, or the network between the departure subsystem and the baggage handling subsystem fails or is delayed, the baggage handling subsystem cannot receive the BSM message in time. In a short period of time, a large amount of baggage may not be transported to the corresponding location because the corresponding flight information cannot be found, causing baggage backlog. At the same time, the airport's already tight network bandwidth and multi-system data transmission requirements also increase the possibility of BSM message delays. In response to this drawback, some peers have proposed a baggage emergency handling method (for example, CN 110586485 A Airport Baggage Emergency Sorting Method and System Based on RFID Technology). When the baggage system cannot receive the BSM message normally, the extended flight information in the RFID baggage chip is read to complete the automatic baggage handling in an emergency. However, this method still has certain disadvantages. First, it can only solve the problem of automatic baggage handling in emergency situations. Under normal circumstances, baggage handling still needs to rely on BSM messages, and there is no improvement in the situation where a large number of BSM messages occupy the airport network bandwidth. Second, even in emergency handling situations, there is no proposed method for generating and processing RFID baggage tag data streams. The current IATA international standard for generating baggage tag data streams is open and transparent. As long as there is RFID data written into the device (the device is not difficult to obtain), anyone can complete the offline generation of baggage tags in the standard format, thereby creating "fake" baggage. In emergency situations, due to the lack of "authenticity verification" capability of BSM messages, the baggage handling subsystem will directly deliver the baggage to the flight according to the information stored in the "fake" baggage tag, resulting in aviation safety risks.

[0005] Therefore, it is necessary to provide a new and improved airport departure baggage tag data generation and processing system and method to solve the above technical problems. Summary of the invention

[0006] The purpose of the present disclosure is to provide an improved airport departure baggage tag data generation and processing system and method in order to solve the above problems.

[0007] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0008] An improved airport departure baggage tag data generation and processing system, comprising a departure subsystem and a baggage handling subsystem;

[0009] The departure subsystem includes a baggage data stream generation module, a baggage data stream encryption module, a baggage data stream writing module and a key synchronization module; the baggage data stream generation module is used to handle baggage consignment services and generate baggage data streams; the baggage data stream encryption module is used to encrypt the baggage data stream according to a predefined key to generate data stream ciphertext; the baggage data stream is used to write the data stream ciphertext into the baggage tag; the key synchronization module is responsible for authorization and authentication control of the visiting system;

[0010] The baggage handling subsystem includes a baggage data stream reading module, a baggage data stream decryption module and a business module; the baggage data stream reading module is used to read the data stream ciphertext stored in the baggage tag; the baggage data stream decryption module uses the latest valid key to decrypt the data stream ciphertext; and the business module completes automatic baggage handling according to the decrypted data stream ciphertext.

[0011] As a further optimization solution of the present disclosure, the baggage data stream includes the passenger's flight information, terminal information, identity information, baggage piece number information and baggage weight information.

[0012] As a further optimization solution of the present disclosure, the baggage data stream encryption module encrypts sensitive information in the baggage data stream, and the sensitive information includes the flight information and the identity information.

[0013] As a further optimization solution of the present disclosure, the baggage data stream writing module writes the data stream ciphertext into the baggage tag barcode or RFID chip in the baggage tag through a baggage tag printer.

[0014] As a further optimization solution of the present disclosure, the key synchronization module is responsible for authorization and authentication control of the visiting system, including:

[0015] The encrypted key is synchronized to the baggage handling subsystem or other authorized external systems that need to handle outbound baggage to ensure that the authorized system can parse the baggage tag through the key and complete the automated baggage handling.

[0016] An improved airport departure luggage tag data generation and processing method applied to the improved airport departure luggage tag data generation and processing system comprises the following steps:

[0017] The departure subsystem handles baggage check-in for passengers, and the baggage data stream generation module generates baggage data stream;

[0018] The baggage data stream encryption module uses the latest version of the encryption key of the departure subsystem to encrypt the baggage data stream by using the key to generate a data stream ciphertext;

[0019] The data stream ciphertext and the secret key version are written into the luggage tag through the luggage data stream writing module to complete the print output;

[0020] The baggage handling subsystem identifies information in the baggage tag based on a reading device and reads the data stream ciphertext stored therein;

[0021] The baggage data stream decryption module checks the currently valid decryption key version of the baggage handling subsystem. If it is consistent with the key version in the baggage tag, the data stream ciphertext is decrypted using the key, the corresponding passenger and flight information is identified, and then passed to the business module;

[0022] The business module matches the detailed information of the received luggage with the processing rules stored in its own system to complete the automatic processing of the luggage.

[0025] Update the validity period of the secret key through the departure subsystem configuration settings; according to the settings, after the new version of the secret key is generated, a preset character will be added after the secret key version number in the baggage data stream, indicating that there is a new version of the secret key that needs to be updated by the downstream system; at this time, the secret key used for encryption is still the next newest version of the key;

[0026] After the encrypted version information in the luggage tag is read by the data stream decryption module, it is compared with the secret key version information stored in itself. If the secret key version is consistent, decryption is used; if the preset characters are found, the secret key information query interface needs to be called to obtain the latest version of the secret key, which is stored in its own system and waits for use;

[0027] After the departure subsystem recognizes that the baggage handling subsystem has obtained the preset time of the new secret key, it starts to use the new secret key to encrypt the baggage data stream, and at the same time, the latest version number is written to the secret key version number position.

[0028] As a further optimization solution of the present disclosure, if the baggage handling subsystem loses the key information, the key information query interface can be called to obtain the corresponding version key.

Only the authorized and legal luggage handling subsystem can receive the key and decrypt the information in the luggage tag, thereby completing the automatic luggage handling safely. The automatic luggage handling no longer relies on BSM messages, saving airport network bandwidth resources, and also solving the security risk of "fake" luggage mixing into production flights in the absence of BSM message verification. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 is a system structure block diagram in an embodiment of the present disclosure;

[0036] Figure 2 is a flow chart of a method in an embodiment of the present disclosure;

[0037] Figure 3 It is a block diagram of the device structure in an embodiment of the present disclosure. DETAILED DESCRIPTION

[0038] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0039] like Figure 1 As shown, an improved airport departure baggage tag data generation and processing system includes a departure subsystem and a baggage handling subsystem;

[0040] The departure subsystem in this embodiment mainly includes four modules:

[0041] The baggage data stream generation module is a system module that handles baggage check-in for passengers and generates online baggage tag data. It generates baggage data streams based on passenger flight, terminal, identity, number of pieces of baggage, weight and other information, and provides a data source for subsequent baggage circulation and automated processing.

[0042] The baggage data stream encryption module encrypts sensitive information such as flight and passenger identity in the data stream according to the pre-defined key to ensure that unauthorized personnel and systems cannot decrypt or identify relevant sensitive information;

[0043] The baggage data stream writing module is responsible for writing the encrypted baggage tag data stream into the baggage tag barcode or RFID chip through the baggage tag printer;

[0044] Key synchronization module: responsible for authorization and authentication control of visiting systems; synchronizes the key used by the departure subsystem to encrypt the baggage tag data stream to the baggage handling subsystem or other authorized external systems that need to handle outbound baggage, to ensure that the authorized external system can parse the baggage tag through the key to complete the automated baggage handling.

[0045] Luggage tag: Printed by a luggage tag printer and attached to the luggage, its barcode or RFID chip stores the passenger's luggage and flight information (encrypted text). After being recognized by the authorized baggage handling subsystem, it can be decrypted and the luggage can be automatically processed (such as automatic sorting).

[0046] In this embodiment, the baggage handling subsystem mainly includes a baggage data stream reading module, a baggage data stream decryption module, and a business module. The baggage data stream reading module reads the encrypted information stored in the baggage tag through a barcode or RFID reading device, and transmits it to the baggage data stream decryption module. The baggage data stream decryption module uses the latest valid key to decrypt the baggage tag data, identifies the flight information corresponding to the baggage tag, and transmits it to the business module. The business module completes automatic baggage handling (for example, transmits it to the corresponding flight sorting position) according to the flight information, location information, and baggage handling rule information.

[0047] like Figure 2 As shown, the baggage handling process is as follows:

[0048] Step 1: The departure subsystem checks in luggage for passengers, and the luggage data stream generation module generates a luggage tag data stream containing luggage number and flight information.

[0049] Step 2: The baggage data stream encryption module uses the latest version of the encryption key of the departure subsystem to encrypt the baggage tag data stream generated in step 1; the baggage data stream encryption module writes the encrypted data stream and the secret key version into the baggage tag to complete the printout.

[0050] Step 3: The baggage handling subsystem identifies the baggage tag information through a reading device, reads the data stream ciphertext stored therein, and transmits it to the baggage data stream decryption module.

[0051] Step 4: The baggage data stream decryption module checks the currently valid decryption key version of the baggage system. If it is consistent with the key version in the baggage tag, the data stream ciphertext is decrypted using the key, the corresponding passenger and flight information is identified, and passed to the business module.

[0052] Step 5: The business module matches the received baggage details with the processing rules stored in its own system, such as transferring the baggage of a certain flight to a certain sorting port, thereby completing the automatic processing of the baggage.

[0053] In this embodiment, the key synchronization method is as follows:

[0054] Step 1: The key synchronization module provides the latest and next-latest versions of key information query interfaces.

[0055] Step 2: The departure subsystem can update the key validity period through configuration settings (configurable to, for example, 1 day / week / month); according to the settings, after the new version of the key is generated, a "U" character will be added after the key version number in the baggage data stream, indicating that a new version of the key needs to be updated by the downstream system; at this time, the key used for encryption is still the next latest version of the key.

[0056] Step 3. After the data stream decryption module of the baggage handling subsystem reads the encrypted version information in the luggage tag, it compares it with the secret key version information stored in itself. If the secret key version is consistent, decryption is used; if a U character is found, the interface in step 1 needs to be called to obtain the latest version of the secret key, which is stored in its own system and waits for use. If the baggage handling subsystem loses the secret key information, it can also call the interface in step 1 to obtain the corresponding version of the secret key.

[0057] Step 4. One hour after the departure subsystem recognizes that the baggage handling subsystem has obtained the new key (configurable), it starts to use the new key to encrypt the baggage data stream, and at the same time, the latest version number is written to the key version number position.

[0058] In this embodiment, the luggage tag data stream encryption method based on the RFID standard includes:

[0059] Step 1: The baggage handling system calls the key synchronization module to obtain the latest version of the key.

[0060] Step 2: The departure system checks in the passenger's luggage and generates an extended luggage tag containing the luggage number and flight information. The departure system encrypts the information, writes it into the RFID chip in the luggage tag, and prints it into the chip of the luggage tag.

[0061] Based on the RFID writing standard, this system writes the content of unit number B3 in an encrypted manner:

[0062]

[0063] Compared with the traditional luggage tag that only writes the luggage number, this writing method expands the information content of the luggage tag, writes the flight and flight segment information into the RFID chip together, and encrypts it.

[0064] Step 2: After the baggage handling reads the baggage tag, it uses the corresponding key to decrypt it according to the key version number.

[0065] Step 3: After decryption, the baggage handling system identifies the information in the RFID chip, reads the baggage number (6420091806), flight information (CX1629T), flight date (168), etc., and delivers the baggage to the corresponding location according to the flight information, completing the automatic processing.

[0066] In this embodiment, the luggage tag data stream encryption method based on the one-dimensional code includes:

[0067] Step 1: The baggage handling system calls the key synchronization module to obtain the latest version of the key.

[0068] Step 2: The departure system checks in the passenger's luggage and generates an extended luggage tag containing the luggage number and flight information. The departure system encrypts the information, writes it into the one-dimensional code area of ​​the luggage tag, and prints it on the luggage tag.

[0069] According to the "China Air Information Baggage Tag Printing Standard", this system will write the encrypted information into unit #09, and the printer will print the content of unit #09 as:

[0070]

[0071] Compared with the traditional luggage tag that only writes the luggage number, this writing method expands the information content of the luggage tag and writes the flight and flight segment information into the one-dimensional barcode.

[0072] Step 3: After the baggage handling device reads the baggage tag, it uses the corresponding key to decrypt it according to the key version number.

[0073] Step 4: After decryption, the baggage handling system identifies the information in the barcode, reads the baggage number (6420091806), flight information (CX1629T), flight date (168), etc., and delivers the baggage to the corresponding location according to the flight information, completing the automatic processing.

[0074] The present disclosure demonstrates significant superiority and innovation in multiple dimensions, which are specifically reflected in the following aspects:

[0075] Enhanced baggage handling security: By introducing encryption mechanism in baggage tag data, this solution significantly improves the security level of baggage handling. Traditional open and transparent data formats are vulnerable to tampering and forgery, while this solution ensures that flight sensitive information is stored in the baggage tag in an encrypted state, which can only be decrypted by a strictly authenticated system, effectively preventing the mixing of "fake" baggage, greatly reducing aviation safety risks, and ensuring the safety of passengers' property and flight operation order.

[0076] Optimize network resource utilization: This technical solution no longer relies on real-time BSM message interaction, reducing the airport network bandwidth usage, especially during peak hours. This optimization is particularly important. It alleviates network congestion problems, allowing the airport's information system to serve other key business processes more efficiently, improving overall operational efficiency.

[0077] Improve baggage handling flexibility and reliability: Even in the case of network failure or communication delay between the departure system and the baggage handling system, this solution can automatically complete the correct sorting of baggage through encrypted baggage tag data. This not only enhances the emergency handling capability of the baggage handling system, but also ensures the continuity and stability of the baggage handling process, reducing the baggage backlog caused by system failures.

[0078] Standardization and compatibility: Although encryption is introduced, this solution still maintains good compatibility with existing baggage handling systems and technical standards. Through a standardized key management mechanism, it ensures seamless connection between baggage handling systems at different airports and suppliers, facilitating promotion and implementation, while retaining compliance with IATA standards and promoting international applications.

[0079] Dynamic key management mechanism: This solution implements dynamic key update and synchronization, enhancing the security of the system. The practice of regularly changing keys effectively prevents the potential risks brought by the long-term use of a single key. At the same time, through the flexible design of the key synchronization module, it ensures that the baggage handling system can instantly obtain and use the latest valid key, maintaining the timeliness and security of data processing.

[0080] In summary, the technical solution disclosed in the present invention not only solves the problems of the existing baggage handling system's strong dependence on BSM messages, low security, and large network resource usage, but also brings higher security and efficiency to airport baggage handling through innovative encryption processing and key management mechanisms, and provides an advanced technical paradigm for automated baggage handling in the global aviation industry, demonstrating significant practical value and industry promotion potential.
