Description

Technical Field

[0001] This utility model belongs to the field of security equipment technology, and in particular relates to a multi-coordinated verification security cabinet. Background Technology

[0002] A security cabinet is a secure storage device specifically designed for storing confidential documents, important data, and valuables. It is typically made of high-strength steel and equipped with multiple protective devices such as mechanical locks, electronic combination locks, and biometric locks, providing multiple security features including anti-pry, fireproof, and anti-magnetic properties. Widely used in government agencies, enterprises, and research institutions, it effectively ensures the secure storage and management of classified information and is an indispensable component of information security protection systems.

[0003] Currently, the locks used in existing safes generally suffer from insufficient security, mainly due to two aspects: the limited number of unlocking methods and the inherent limitations of each type of lock. Firstly, in terms of unlocking methods, most traditional safes still use mechanical locks or single combination locks as the primary unlocking means. Although these structures are low in manufacturing cost and simple to operate, they lack multi-factor authentication or collaborative authentication mechanisms.

[0004] Secondly, regarding specific lock types, mechanical locks, relying on physical keys for unlocking, have several key problems: First, keys are easily lost, rendering the safe unusable or allowing unauthorized entry. Second, keys are easily copied, especially ordinary keys without special tooth patterns or anti-copying designs; the difficulty of copying is low, and the security risk is high. While combination locks improve security to some extent, they also suffer from the problem of passwords being easily spied on, forgotten, or cracked. In practical use, if users set simple passwords or frequently reuse the same password, security will be significantly reduced. Utility Model Content

[0005] In view of the problems of existing safe locks having a single unlocking method, lack of multiple verification mechanisms, easy loss and duplication of mechanical locks, and easy spying or cracking of combination locks, resulting in insufficient overall security, this utility model provides a safe with multiple collaborative verification.

[0006] This utility model is implemented as follows: a multi-coordinated verification security cabinet includes a cabinet body and a cabinet door, characterized in that: the outer side of the cabinet door is equipped with a mechanical lock, a combination lock, a first palm print and palm vein recognition lock, and a second palm print and palm vein recognition lock; a control module is fixed to the inner wall of the cabinet door, its input end is electrically connected to the first palm print and palm vein recognition lock, the second palm print and palm vein recognition lock, and the combination lock respectively via data lines, and its output end is connected to an electromagnetic locking mechanism via a relay; the electromagnetic locking mechanism includes an electromagnet and a spring latch, the spring latch being mechanically coupled to the bolt of the mechanical lock; a countdown module is integrated on the PCB board of the control module and connected to the main control chip via a crystal oscillator circuit; the acquisition windows of the first palm print and palm vein recognition lock and the second palm print and palm vein recognition lock are symmetrically distributed on the surface of the cabinet door.

[0007] In the above technical solution, preferably, the spring buckle of the electromagnetic locking mechanism is an L-shaped stainless steel component, with a magnetic absorbing piece at the end of its short arm corresponding to the electromagnet armature, and a limiting groove on the long arm matching the mechanical locking tongue.

[0008] In the above technical solution, preferably, a 4G communication chip and a SIM card slot are soldered on the PCB board of the control module, and the antenna of the 4G communication chip is embedded in the cabinet door interlayer.

[0009] In the above technical solution, preferably, a backup power compartment is provided on the inside of the cabinet door, and a lithium battery pack is installed in the compartment and connected to the power supply interface of the control module through a step-down circuit.

[0010] In the above technical solution, preferably, the mechanical lock includes a rotating handle for driving the lock tongue, and the rotating handle is located on the outer side of the cabinet door.

[0011] This multi-factor authentication safe integrates a mechanical lock, a combination lock, a dual palm print and vein recognition lock, a control module, an electromagnetic locking mechanism, and a countdown module to create a highly secure and reliable comprehensive unlocking system with numerous technical advantages and practical application benefits.

[0012] First, it employs a four-tiered collaborative verification structure: a mechanical lock, a combination lock, a first palmprint and vein recognition lock, and a second palmprint and vein recognition lock. The control module only issues an unlocking command when all verification conditions are met simultaneously, significantly enhancing the protection level and effectively preventing unauthorized opening due to a single lock being cracked or bypassed. Second, the dual palmprint and vein recognition locks are symmetrically arranged on the outer surface of the cabinet door, requiring simultaneous recognition of two palmprints. This greatly enhances the anti-counterfeiting capabilities of biometric identification, reduces the risk of palmprint information being copied or forged, and ensures the legitimacy of the user's identity. Furthermore, the control module manages each verification step uniformly. Its integrated countdown module can limit the verification time window, improving the standardization and timeliness of operations. Simultaneously, a relay controls the electromagnetic locking mechanism, achieving precise control of the spring latch, ensuring that the mechanical lock's bolt can only be released after all verification conditions are met, thus achieving an organic combination of electronic control and physical locking. In summary, this security cabinet not only enhances anti-theft and anti-hacking capabilities, but also strengthens operational logic and security during use, making it suitable for government agencies, classified units, corporate archives management, and other places with high requirements for confidentiality protection.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0016] To address the problems of existing safes having limited unlocking methods, lack of multi-factor authentication mechanisms, and the ease with which mechanical locks can be lost or copied, and the vulnerability of combination locks to spying or cracking, resulting in insufficient overall security, this invention provides a safe with multi-factor authentication. To further illustrate the structure of this invention, a detailed description is provided below in conjunction with the accompanying drawings:

[0017] Please see Figure 1 and Figure 2 A multi-factor authentication security cabinet includes a cabinet body 1 and a cabinet door 2. The cabinet door is equipped with a mechanical lock 3, a combination lock 4, a first palmprint / palm vein recognition lock 5, and a second palmprint / palm vein recognition lock 6 on its outer side. A control module is fixed to the inner wall of the cabinet door. Its input terminal is electrically connected to the first palmprint / palm vein recognition lock, the second palmprint / palm vein recognition lock, and the combination lock via data cables. Its output terminal is connected to an electromagnetic locking mechanism 7 via a relay.

[0018] The cabinet is a sealed box structure made of cold-rolled steel plate, with a preferred outer shell thickness of 2.0mm. It features multiple adjustable partitions inside for storing classified documents or valuables of different levels or types. The four walls of the cabinet are lined with fire-resistant and heat-insulating materials, such as intumescent flame-retardant boards, to improve overall fire resistance. The bottom of the cabinet has fixing holes for securing it firmly to the ground with expansion bolts, enhancing its anti-pry and anti-movement capabilities. A cable pass-through hole with a rubber sealing ring is provided on the back panel of the cabinet for easy access to external power or signal lines, while ensuring dust and moisture protection.

[0019] The cabinet door employs a double-layer sandwich structure, comprising an outer steel plate and an inner reinforcing plate, preferably ≥4mm thick. The sandwich is filled with polyurethane foam to enhance the overall structure's impact resistance and provide heat insulation and noise reduction. The cabinet door is hinged to the cabinet body via multi-point linkage hinges, allowing for an opening angle of over 90° for easy access to items. Flexible sealing strips are installed around the cabinet door, forming an effective seal when closed, preventing dust and moisture from entering and improving overall resistance to damage. To facilitate the precise operation of the electromagnetic locking mechanism, a limit guide rail is embedded within the cabinet door to guide the latch's extension and retraction in specific directions, preventing misalignment or jamming between the latch and the door, and improving opening and closing sensitivity and stability.

[0020] Mechanical locks serve as the basic locking structure for existing safes. This technical solution does not limit their specific structure. In this embodiment, the mechanical lock is a high-security blade-type lock cylinder structure, installed on the outer front of the cabinet door. Its lock body contains multiple sets of irregularly shaped blades and spring mechanisms. A special anti-counterfeiting key is required to accurately move all blades to the unlocked position. The lock tongue is made of thickened alloy steel, with a limit stop machined on the side. This stop is used to mechanically couple with the spring latch in the electromagnetic locking mechanism to form a double locking structure. In the unlocked state, the lock tongue is fully extended and engages with the inner wall of the cabinet, achieving primary physical locking. When the electromagnetic locking mechanism is not engaged, the long arm of the spring latch is located in the lock tongue's travel path, preventing the lock tongue from retracting through limit misalignment, thus forming secondary locking. Only when the control module determines that the mechanical lock is open, password verification, and dual palm print recognition have all passed, does the control module drive the electromagnet to retract the long arm of the spring latch to the aligning position of the limit groove, allowing the lock tongue to retract and finally unlock. Therefore, this mechanical lock not only performs traditional physical protection functions, but also works in conjunction with the electronic control device to construct a multi-linked locking system, significantly enhancing security performance and resistance to damage. In this embodiment, the mechanical lock includes a rotating handle for driving the bolt, and the rotating handle is located on the outer side of the cabinet door.

[0021] The electromagnetic locking mechanism includes an electromagnet and a spring latch 7-1, which is mechanically coupled to the bolt of the mechanical lock. The spring latch of the electromagnetic locking mechanism is an L-shaped stainless steel component. Its short arm has a magnetic attracting piece at its end corresponding to the electromagnet's armature, and its long arm has a limiting groove 7-2 that matches the mechanical bolt. That is, the side of the bolt 3-1 forms a limiting stop 3-2. When the magnetic attracting piece and the spring latch are not engaged, and the long arm is extended, this stop is misaligned with the limiting groove of the long arm. When the electromagnetic locking mechanism is triggered, the magnetic attracting piece and the spring latch engage, the long arm retracts, the limiting groove of the long arm aligns, and the bolt can retract to unlock.

[0022] The countdown module is integrated on the PCB board of the control module and connected to the main control chip via a crystal oscillator circuit. The crystal oscillator circuit of the countdown module uses an 8MHz quartz crystal with an error of ±50ppm.

[0023] The acquisition windows of the first and second palmprint and palm vein recognition locks are symmetrically distributed on the cabinet door surface. A backup power compartment is located inside the cabinet door, housing a lithium battery pack, which is connected to the control module's power supply interface via a step-down circuit. As an existing biometric unit component, the palmprint and palm vein recognition lock uses the MV935 model, achieving dual authentication through the combination of the palmprint recognition unit and the palm vein recognition unit.

[0024] In the above specific embodiment, the control module is an electronic control unit integrated into the inner wall of the cabinet door, mainly used for unified management and logical judgment of various authentication devices and locking mechanisms of the safe. The control module has a multi-layer PCB board on which functional components such as the main control chip, countdown module, 4G communication chip, SIM card slot, power management circuit, and relay control circuit are soldered. The main control chip is an industrial-grade MCU with multi-channel digital signal input and output capabilities, capable of receiving authentication signals from the first palm vein recognition lock, the second palm vein recognition lock, and the password lock. The control module sets up collaborative verification logic through internal programming, requiring simultaneous mechanical lock opening, correct password input, and simultaneous recognition of both palm veins before outputting a drive signal to the relay to trigger the electromagnetic locking mechanism.

[0025] Furthermore, the countdown module integrated into the control module limits the effective time window for multiple verifications. Its crystal oscillator circuit uses an 8MHz quartz crystal, with a time error controlled within ±50ppm, ensuring the stability and accuracy of the verification process. If verification fails or the operation is interrupted within the set time, the system will automatically reset and issue a failure warning signal to prevent malicious repeated attempts to crack the system. For remote communication and status monitoring, the control module is equipped with a 4G communication chip. Its antenna is embedded inside the cabinet door interlayer, enabling wireless connection with the management terminal or security backend to achieve functions such as unlocking log upload, remote lock control, and abnormal alarms. The entire control module is connected to a built-in backup lithium battery pack via a voltage regulator circuit, allowing it to maintain short-term operation even in the event of a mains power outage, ensuring unaffected security performance. This control module's design gives the security cabinet a highly intelligent and integrated operational capability, serving as the core supporting unit for the multiple collaborative verification mechanism.

[0026] Palmprint and vein recognition locks, as an existing technology, employ optical or capacitive sensing technology to collect the texture features, vein distribution, or palm shape contours of the palm, enabling biometric identification of the user. These locks are typically installed on the outer surface of cabinet doors and are equipped with a dedicated acquisition window and sensors, allowing for rapid collection and comparison of palm feature information. Palmprint and vein recognition locks offer contactless or touch-based operation, providing convenience and avoiding the security risks associated with traditional keys or passwords. Internally, they are equipped with a dedicated processing chip and storage module for storing authorized palmprint templates and executing comparison algorithms, supporting multi-user management and recognition record retrieval.

[0027] Detailed procedure for unlocking this safe:

[0028] Step 1: First Palm Vein Authentication

[0029] Staff member A places their palm on the palm vein recognition lock's palm vein scanning area, ensuring the palm completely covers the scanning area. They keep their hand steady and wait for the system to scan and recognize the vein.

[0030] (1) If the recognition is successful, the system will issue a prompt sound (such as "authentication successful").

[0031] (2) If the identification fails, the safe will not respond. In this case, you need to place your palm again for scanning.

[0032] Step 2: Second Palm Vein Authentication

[0033] Staff member B places their palm on the palm vein scanning area of ​​another palm vein recognition lock within a specified time (e.g., 10 seconds). They keep their palm stable and wait for the system to scan and recognize the vein.

[0034] (1) If the recognition is successful, the system will issue a prompt sound (such as "authentication successful").

[0035] (2) If the identification fails, the safe will not respond. In this case, you need to place your palm again for scanning.

[0036] Step 3: Password Authentication

[0037] After successful authentication via both palm vein scans, enter your password within the specified time (e.g., 10 seconds). Use the numeric keypad on the keypad to enter the preset password: please shield your hand while entering the password to prevent others from watching. Press the "Confirm" button after entering the password.

[0038] (1) If the password is correct, the system indicator light will light up.

[0039] (2) If the password is wrong, the safe will not respond. You will need to re-enter the password.

[0040] Step 4: Unlock

[0041] Once both palm vein authentication and password authentication are successful, the staff can turn the handle and open the cabinet door.

[0042] 2. Automatic locking function

[0043] After the staff closes the cabinet door, the system will check the door status. If the door is completely closed, the system will automatically lock within a specified time (e.g., 10 seconds), and the safe will be closed.

[0044] 3. Re-authentication mechanism

[0045] The system will automatically trigger a re-authentication mechanism if it detects any of the following:

[0046] (1) Any palm vein authentication failed.

[0047] (2) Password authentication failed.

[0048] This technical solution features a multi-factor authentication unlocking mechanism: the system ensures successful completion of both palm vein authentication and password authentication, and unlocks the cabinet only after all authentications are successful, within a specified time. This mechanism aims to ensure that only authorized personnel can open the cabinet, thus enhancing security.

[0049] Equipped with automatic locking function: Designed and installed with a mechanism that automatically locks the door within a specified time after it is closed to prevent safety hazards caused by negligence or forgetting to lock the door.

[0050] Re-authentication mechanism: If the system detects that one or more authentication methods have failed, or that no authentication operation has been performed within a specified time, the system will automatically trigger the re-authentication mechanism, requiring the user to repeat the entire authentication process of both palm veins and the password.

[0051] Strict authentication requirements: The system's authentication method must simultaneously meet all three conditions of the palmprint and palm vein recognition locks; none can be omitted. If any authentication condition is missing, the cabinet will not be able to open, thus ensuring the system's security and reliability.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
