Description

Technical Field

[0001] The present invention relates to the field of lock production, and in particular to a spatial three-dimensional encryption lock and a production management method and system thereof. Background Art

[0002] Traditional mechanical door locks use a "spring-slider" combination to form two states between the inner lock body and the outer lock body: blocking and releasing. That is, when the interface of the two sliders is aligned with the interface of the inner and outer lock bodies, the sliders cannot form a blocking obstacle between the upper and lower lock holes, and the inner lock body can rotate or move under the torque transmitted by the key to reach the unlocked state. On the contrary, part of the slider is in the lock hole of the outer lock body, and part of it is in the lock hole of the inner lock body. Its rigidity prevents the relative movement of the inner and outer lock bodies, and it cannot be unlocked.

[0003] The current encryption of locks is generally two-dimensional. One dimension is along the direction of the key. The distribution of multiple "spring-sliders" constitutes a set of encrypted content (one-to-one correspondence with the teeth on the key tooth surface). The second dimension is the different key tooth heights corresponding to each "spring-slider", which constitutes the second set of encrypted information. As for some methods such as multi-tooth surface keys, they only increase the number of units encrypted in the above two dimensions, and there is no essential change. This is the so-called "key embryo". In the market that is completely unrelated to lock encryption, there is a "key blank". As long as its tooth surface is processed accordingly, the corresponding key can be obtained. Corresponding to this, once illegal infringers have a way to obtain the same tool as the "key embryo", they can easily open the lock, which greatly reduces the security value of the lock.

[0004] It can be seen that the locks of the prior art still have inconveniences and defects in structure, method and use, and are in urgent need of further improvement. How to create a spatial three-dimensional encryption lock with significantly improved security and confidentiality and its production management method and system has become a goal that the industry urgently needs to improve. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a spatial three-dimensional encryption lock with significantly improved security and confidentiality and a production management method and system thereof, thereby overcoming the deficiencies of the prior art.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A spatial three-dimensional encryption lock, comprising a key and a matching lock, wherein the key comprises a key body, on which a tooth surface is arranged; the matching lock comprises an inner lock body, an outer lock body and a spring-slider module movable in lock holes of the inner and outer lock bodies; the lock hole and the spring-slider module are arranged corresponding to the teeth on the tooth surface of the key; the key has at least two tooth surfaces, and the key is manufactured by 3D printing based on three-dimensional encryption parameters randomly generated during production;

[0008] The three-dimensional encryption parameters include:

[0009] Number of key teeth;

[0010] The angle between each key tooth surface and the vertical upper surface of the lock or the angle between the tooth surfaces;

[0011] The number of teeth per tooth flank;

[0012] The position of each tooth on each tooth flank;

[0013] The height of each tooth on each tooth flank.

[0014] As a further improvement of the present invention, the teeth on each tooth surface are arranged at randomly variable intervals along the axial direction of the key body, and correspondingly, the lock hole and the spring-slider module in the matching lock are arranged at randomly variable intervals.

[0015] Furthermore, the three-dimensional encryption is three-dimensional polar coordinate encryption, and the three-dimensional polar coordinate encryption parameters include:

[0016] m: number of key teeth;

[0017] θ1~θ m : The angle between the first to m key tooth surfaces and the vertical upper surface of the lock;

[0018] n i : The number of teeth on the i-th tooth surface, i = 1 ~ m;

[0019] r ij : The position of the jth tooth on the i-th tooth surface, which is the distance from the lock surface, i = 1 ~ m;

[0020] h ij : The height of the jth tooth on the ith tooth surface, i=1~m.

[0021] Furthermore, the three-dimensional encryption is three-dimensional rectangular coordinate encryption.

[0022] Furthermore, the inner lock body and the outer lock body are manufactured by 3D printing, and then form a matching lock with the spring-slider module.

[0023] Furthermore, when the lock is a "switch" in which the inner lock body rotates relative to the outer lock body, a three-dimensional polar coordinate encryption form is adopted;

[0024] When the lock is a "switch" in which the inner lock body telescopically moves inside the outer lock body, a three-dimensional rectangular coordinate encryption form is adopted.

[0025] In a second aspect, the present invention provides a production management method for the above-mentioned three-dimensional spatial encryption lock, comprising:

[0026] For each spatial three-dimensional encryption lock to be produced, the data production and management center generates a set of three-dimensional encryption parameters and lock parameter data packets, which are stored in the confidentiality database;

[0027] During production, a data packet is called out and injected into a 3D printing processing center, and a number of keys and the corresponding inner lock body and outer lock body of the matching lock are produced according to the parameters. The inner lock body and the outer lock body then form a matching lock with the matching spring-slider module.

[0028] Furthermore, part of the key is sold with the lock, and part is stored in a confidential warehouse; the user can apply to purchase a replacement key based on the secret code set when purchasing the lock.

[0029] In a third aspect, the present invention also provides a production management system for the above-mentioned three-dimensional spatial encryption lock, including: a data generation and management center, a confidentiality database and a 3D printing processing center;

[0030] The data generation and management center is used to generate a set of three-dimensional encryption parameters and lock parameter data packets for each lock to be produced;

[0031] The confidentiality database is used to store three-dimensional encryption parameters and lock parameter data packets;

[0032] The 3D processing center is used to produce a number of keys and the corresponding inner lock body and outer lock body of the matching lock according to the three-dimensional encryption parameters and the lock parameter data packet. The inner lock body and the outer lock body can be combined with the matching spring slider to form a matching lock.

[0033] Furthermore, it also includes an online service software platform for providing users with full life cycle services, and the users can apply to purchase replacement keys based on the password set when purchasing the lock.

[0034] By adopting the above technical solution, the present invention has at least the following advantages:

[0035] The present invention provides a distributed encryption method in three dimensions of space based on the interdependence principle of three-dimensional spatial coordinates, thereby providing a three-dimensional encryption lock. According to the matching design that is mutually adapted to the practical environment, two technical approaches, polar coordinate three-dimensional encryption and rectangular coordinate three-dimensional encryption, are selected to provide the society with a lock with significantly improved security and confidentiality.

[0043] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0044] The present invention provides a distributed encryption method in three dimensions of space based on the interdependence principle of three-dimensional spatial coordinates, thereby providing a three-dimensional spatial encryption lock. According to the matching design that is mutually adapted to the practical environment, two technical approaches, polar coordinate three-dimensional encryption and rectangular coordinate three-dimensional encryption, are selected to set encryption with coordinates as the dimension, providing the society with a lock with significantly improved security and confidentiality.

[0045] Example 1

[0046] This embodiment provides a three-dimensional encryption lock, which uses a three-dimensional polar coordinate space encryption method. Figure 1 As shown, in a three-dimensional space described by polar coordinates, a coordinate point P is described by three parameters, namely P(r, θ, а):

[0047] Corresponding to the lock, taking the key as the description object, ①а-dimensional encryption method: use the tooth height of the tooth on the key corresponding to the "spring-slider module" as the encryption link, which is the continuation of the traditional encryption method. ②r-dimensional encryption method: change the uniform distribution encryption method between the "spring-slider modules" in the traditional lock to a randomly distributed variable spacing encryption scheme (that is, the random distribution variable spacing encryption between the teeth of the key). ③θ-dimensional encryption method: set the key to several (m≥2) tooth surface structures, corresponding to several (m≥2) groups of "spring-slider modules". Change the angle between the tooth surfaces, with the center of the lock upward as the zero point. There is an angle between each tooth surface and the zero point direction, and there are m angle θ values ​​for m tooth surfaces. These m θ values ​​become the third encryption link created by the present invention.

[0048] According to the above three-dimensional polar coordinate principle, this embodiment provides a three-dimensional encryption lock. Figure 2 (a)(b)(c) As shown; the spatial three-dimensional encryption lock includes a key 1 and a matching lock 2, the key 1 includes a key body 11, and the key body 11 is provided with tooth surfaces 12 and 13; the matching lock 2 includes an inner lock body 21, an outer lock body 23 and a spring-slider module (not shown in the figure) that can move in the lock hole 22 of the inner and outer lock bodies; the lock hole 22 and the spring-slider module (traditional method) are arranged corresponding to the teeth on the tooth surface of the key 1, and the teeth on the tooth surface of the key 1 are used as contacts to trigger the spring-slider module to move to the correct position. At least two tooth surfaces 12 and 13 can be arranged on the key body 11, and a key insertion hole 31 is processed on the inner lock body 21, and there are gaps 32 and 33 on the hole for two tooth surfaces to be inserted. This embodiment takes two tooth surfaces as an example for explanation, and the key 1 is manufactured by 3D printing based on three-dimensional encryption parameters. The three-dimensional encryption parameters include:

[0049] Number of key teeth;

[0050] The angle between each key tooth surface and the vertical upper surface of the lock;

[0051] The number of teeth per tooth flank;

[0052] The position of each tooth on each tooth flank;

[0053] The height of each tooth on each tooth flank.

[0054] Among them, the above three-dimensional encryption parameters are all parameters randomly generated during production.

[0055] Preferably, the teeth on each tooth surface 12, 13 are arranged at randomly variable intervals along the axial direction of the key body 11, and correspondingly, the lock hole 22 and the spring-slider module in the matching lock are arranged at randomly variable intervals.

[0056] Specifically, the above three-dimensional polar coordinate encryption parameters include:

[0057] m: number of key tooth surfaces; 2 is selected in this embodiment;

[0058] θ1~θ m : The angle between the first to m key tooth surfaces and the vertical upper surface of the lock;

[0059] n i : The number of teeth on the i-th tooth surface, i = 1 ~ m;

[0060] r ij : The position of the jth tooth on the i-th tooth surface, which is the distance from the lock surface, i = 1 ~ m;

[0061] h ij : The height of the jth tooth on the ith tooth surface, i=1~m.

[0062] Figure 2 In (a)(b)(c), the key insertion hole 31 has gaps 32 and 33 for the two tooth surfaces to pass through. Since the absolute and relative positions of the two tooth surfaces 12 and 13 are unknown (randomly generated during production), the owner cannot find a matching "key blank" to copy the key. It is extremely difficult to use a combination tool to simultaneously unlock three sets of codes in a small space, which constitutes the core of three-dimensional space encryption.

[0063] Figure 2 In (a)(b)(c), the angle between the two tooth surfaces 12 and 13 is equivalent to θ (or it can be understood that the angles between the two tooth surfaces 13 and 12 and the vertical upper surface of the lock are θ1 and θ2 respectively, and the vertical upward coordinate is the zero point direction), the unique angle of θ is the encryption core parameter, and D is the axial encryption parameter of a certain contact (equivalent to the distance from the lock surface to the lock hole).

[0064] P is the contact position (the position of the tooth corresponding to the spring-slider module, which corresponds to the top of the key in the hole). After the key is inserted, the inner lock body can be rotated to unlock the lock only when all the three-dimensional parameters of the contacts are correct.

[0065] In this embodiment, the inner lock body 21 and the outer lock body 23 are manufactured by 3D printing, and form a matching lock with the matching spring-slider module.

[0066] The above-mentioned spatial three-dimensional encryption lock adopts a special production management method, which is based on an integrated password generation, management, manufacturing, and service system (equivalent to a production management system). The system consists of core modules such as a data generation and management center, a confidentiality database, a 3D printing processing center (including 3D printing manufacturing equipment), and an online service software platform.

[0067] Combination Figure 3 As shown, its production management method is:

[0068] For each spatial three-dimensional encryption lock to be produced, the data production and management center generates a set of three-dimensional encryption parameters and lock parameter data packets, which are stored in the confidentiality database;

[0069] During production, a data packet is called out and injected into a 3D printing processing center, and a number of keys and the inner lock body and the outer lock body of the corresponding matching lock are produced according to the parameters. The inner lock body and the outer lock body are then combined with the matching spring-slider module to form a matching lock;

[0070] Part of the keys are sold with the locks, and part are stored in a confidential warehouse; using the online service software platform, users can apply to purchase replacement keys based on the secret code set when purchasing the lock.

[0071] The system is managed by the lock manufacturer and provides full life cycle services to users, and is a supporting platform for the promotion and application of the present invention.

[0072] In the present invention, due to the randomness of the number of tooth surfaces and the angle distribution, combined with the randomness of the distribution of the key holes (corresponding teeth and contacts), the lock of the present invention, especially the key, is difficult to manufacture or imitate under general equipment conditions and can only be formed in one step with the help of 3D printing equipment, which is also an important guarantee for encryption.

[0073] The core parameters are:

[0074] 3D encryption parameters:

[0075] am: key tooth surface data.

[0076] b.θ1~θ m : The angle between the key tooth surface and the vertical upper surface of the lock.

[0077] cn i : The number of teeth on the i-th tooth surface.

[0078] dr ij : The position of the jth tooth on the ith tooth surface (distance from the lock surface).

[0079] eh ij : The height of the jth tooth on the ith tooth surface.

[0080] Of course, in addition to the above core parameters, it also includes lock parameter data packets:

[0081] (1) Data packet: the password of this lock.

[0082] The password corresponds to the lock and data packet one by one and is the basis of ownership.

[0083] (2) Specific size parameters are determined by the lock model.

[0084] This set of parameters is converted into production files for 3D printing manufacturing equipment through computational design software, and the key, inner lock body and outer lock body are produced. Springs and sliders of corresponding sizes are selected to form spring-slider modules, which can be assembled into a lock with three-dimensional encryption features. The rigorous and high-standard production process also constitutes an important part of the confidentiality and security of the lock.

[0085] Example 2

[0086] This embodiment provides a three-dimensional spatial encryption lock, which adopts a three-dimensional rectangular coordinate space encryption method. Figure 4 In the figure, X, Y, and Z are used to represent the three-dimensional space of the rectangular coordinate system. The coordinates of point P are represented by P(X, Y, Z), and 0 is the origin of the coordinate system.

[0087] For the rectangular coordinate system, the formation of three-dimensional encryption is no longer formed independently according to the coordinate axis, but is formed in a composite manner on a two-dimensional plane. The core composite is the configuration of n (n ≥ 2) tooth surfaces (such as Figure 5 As shown), in the matching lock, it includes an inner lock body 21 and an outer lock body 23, wherein A and B correspond to two tooth surfaces.

[0088] On the basis of this structural form, the two encryption combination schemes of random distribution encryption in the r direction of polar coordinates and tooth height encryption in the X direction are still used.

[0089] It should be noted that three-dimensional rectangular coordinate encryption is more suitable for push-pull locks, that is, the inner lock body telescopically moves inside the outer lock body to form the "on-off" function of the lock, and polar coordinate encryption is more suitable for the inner lock body to rotate relative to the outer lock body.

[0090] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which all fall within the protection scope of the present invention.
