Description

Technical Field

[0001] The present invention relates to the technical field of security document authentication, and in particular, to a security document, an authentication method and an authentication device thereof. Background Art

[0002] At present, most of the current security documents such as identity cards, passports, bank cards, etc. have incorporated NFC (Near Field Communication) chips or UHF chips (Ultra High Frequency) for information security and anti-counterfeiting. However, on the one hand, the verification result of the chip information is displayed on the authentication device and cannot be viewed through the document itself. On the other hand, after the chip in the document fails, other anti-counterfeiting features are still required to determine its authenticity, and it cannot rely solely on the chip itself for anti-counterfeiting. Therefore, other anti-counterfeiting features, especially easily recognizable anti-counterfeiting features, need to be added to the document. The anti-counterfeiting information of the chip and other anti-counterfeiting features are viewed and determined separately and do not have linkage. With the rapid development of new display technologies and optical anti-counterfeiting technologies, people's demand for the combination of intelligent, information-based, and visible anti-counterfeiting is becoming increasingly strong. This combination can produce new anti-counterfeiting technologies that are eye-catching and attractive to the public, and can improve the anti-counterfeiting ability of security documents. In some documents such as bank cards, small displays such as liquid crystals and electrochromics are connected to the chip for the visualization of anti-counterfeiting information. However, this method requires a power source to be placed in the card. On the one hand, the power source life is limited, and on the other hand, it greatly increases the overall thickness of the document.

[0003] In the related art, an electroluminescent anti-counterfeiting element has been proposed. The electroluminescent anti-counterfeiting element can be driven by a radio wave signal with a frequency greater than or equal to 10 KHz and less than or equal to 500 KHz. The element can form an anti-counterfeiting feature that is easily recognizable by the public and can be recognized by a small, portable wireless charging device or a smart phone. At the same time, it has a small thickness and can be compounded with substrates such as paper for use. However, the element itself does not have an information-based anti-counterfeiting function and needs to be combined with an NFC chip or a UHF chip to achieve the visibility of information-based anti-counterfeiting.

[0004] Therefore, how to combine an NFC chip or a UHF chip with an OLED (Organic Light-Emitting Diode) light-emitting anti-counterfeiting element in a security document so that the two can have a linkage relationship as needed, can independently play an anti-counterfeiting role, and ensure that the thickness and flexibility of the OLED element and the chip meet the usage requirements of the document have become problems that need to be solved urgently at present. Summary of the Invention

[0005] The present invention aims to at least solve the problems that the visual anti-counterfeiting technology and the information-based anti-counterfeiting technology in security documents cannot be integrated, and the current display elements have too high power consumption and require an internal power supply, thus affecting the thickness and service life of the documents.

[0006] To this end, a first aspect of the present invention provides a security document.

[0007] A second aspect of the present invention provides a method for authenticating a security document.

[0008] A third aspect of the present invention provides an authentication device for a security document.

[0009] In view of this, a first aspect of the present invention proposes a security document, including: a substrate; a chip information layer disposed within the substrate; an anti-counterfeiting display layer disposed within the substrate; the chip information layer includes at least one NFC chip and / or UHF chip; the anti-counterfeiting display layer includes at least one light-emitting element, and the light-emitting element can be driven by a wireless charging device meeting a preset power and emission frequency and emit light; the preset power is less than or equal to 80W, and the emission frequency is between 10KHz - 500KHz; the substrate includes at least one of a card-type document and a multi-page document.

[0010] The security document provided by the present invention includes a substrate, a chip information layer, and an anti-counterfeiting display layer. The chip information layer and the anti-counterfeiting display layer are both provided within the substrate. The chip information layer includes at least one NFC chip and / or UHF chip, and the anti-counterfeiting display layer includes at least one light-emitting element that can be driven by a wireless charging device meeting the emission frequency and preset power to emit light. It can be understood that since the security document provided in this application includes a chip information layer and an anti-counterfeiting display layer, the chip information layer and the anti-counterfeiting display layer can be used independently to achieve information authentication and anti-counterfeiting. Also, the two can be combined to produce a linkage, so that the validity of the chip information in the chip information layer can be made visible, and the authenticity of the security document can be determined after the chip information becomes invalid. For example, during use, the chip information layer can be authenticated first, and when the authentication is passed, the light-emitting element of the anti-counterfeiting display layer is triggered to emit light for anti-counterfeiting verification. When the authentication fails, it proves that the chip information layer is invalid or has problems. At this time, the light-emitting element of the anti-counterfeiting display layer can be manually triggered to emit light for anti-counterfeiting verification. In this way, information authentication and anti-counterfeiting verification can be achieved only through the security document. At the same time, since the anti-counterfeiting display layer provided in this application is driven by a wireless charging device to emit light, there is no need to provide a power source within the security document. This not only reduces the thickness of the security document but also eliminates the need to replace the battery within the security document, improving the service life and convenience of the security document. In addition, the security document proposed in this application can solve the problem that in the existing security document authentication process, the authentication result can only be viewed through an authentication device and cannot be displayed on the security document itself. The anti-counterfeiting display layer in the security document can be used for public anti-counterfeiting identification on the one hand and for professionals to view the identification result on the document itself on the other hand, and the viewing method is more direct and eye-catching.

[0011] Among them, the preset power is less than or equal to 80W, and the emission frequency is between 10KHz and 500KHz, preferably between 100KHz and 200KHz. It can be the QI protocol standard. The QI protocol is a wireless charging standard with convenience and universality and has the highest market share. As long as products of different brands have the QI logo, they can be charged with a QI wireless charger. Therefore, the QI protocol has universality. The substrate can be at least one of a card-type document and a multi-page document.

[0012] According to the security document provided by the present invention, it may also have the following additional technical features: In some embodiments, optionally, the emission frequency is greater than or equal to 100KHz and less than or equal to 200KHz. It can be understood that most of the small wireless chargers used in the public's daily life are in this frequency band. Therefore, using this frequency band makes it easier for the public to identify the anti-counterfeiting pattern by themselves, improving the reliability and convenience of information authentication and anti-counterfeiting verification.

[0013] In some embodiments, optionally, the anti-counterfeiting display layer further includes an anti-counterfeiting pattern, and the anti-counterfeiting pattern can be displayed when the light-emitting element emits light.

[0014] In this embodiment, in order to improve the anti-counterfeiting effect, an anti-counterfeiting pattern can be provided on the anti-counterfeiting display layer, so that when the light-emitting element emits light, it can drive the anti-counterfeiting pattern to be displayed, thereby using the anti-counterfeiting pattern for anti-counterfeiting.

The chip information layer is provided between the front cover and the second cover, and the anti-counterfeiting display layer is provided between the third cover and the back cover.

[0020] In some embodiments, optionally, the anti-counterfeiting display layer is provided between the front cover and the second cover, and the chip information layer is provided in an inner page.

[0021] In some embodiments, optionally, the security document further includes: a first electromagnetic induction coil provided in the chip information layer for responding to an electromagnetic signal of a preset frequency band; a second electromagnetic induction coil provided in the anti-counterfeiting display layer for responding to an electromagnetic signal of a preset frequency band; at least a part of the first electromagnetic induction coil and the second electromagnetic induction coil do not overlap.

[0022] In this embodiment, in order to respond to an electromagnetic signal, a first electromagnetic induction coil and a second electromagnetic induction coil may be respectively provided in the chip information layer and the anti-counterfeiting display layer, so as to ensure that the chip information layer can be authenticated and ensure that the anti-counterfeiting display layer is driven to emit light for anti-counterfeiting. Moreover, in order to avoid interference from other electromagnetic signals and avoid information leakage of the security document, the first electromagnetic induction coil and the second electromagnetic induction coil may be set to be capable of only responding to electromagnetic signals in a preset frequency band.

[0023] Wherein, at least a part of the first electromagnetic induction coil and the second electromagnetic induction coil do not overlap, so as to reduce the mutual interference between the first electromagnetic induction coil and the second electromagnetic induction coil.

[0024] In some embodiments, optionally, the light-emitting element includes an OLED light-emitting element.

[0029] In this embodiment, the thickness of the light-emitting element is less than or equal to 70 microns, so as to ensure the overall thickness of the security document.

[0030] A second aspect of the present invention provides a method for authenticating a security document, which can authenticate the security document in any one of the technical solutions of the first aspect. The method for authenticating the security document includes: determining whether the chip information layer meets a preset condition; in the case where the chip information layer does not meet the preset condition, determining that the chip information layer is invalid; in the case where the chip information layer is invalid, in response to an operation of driving the anti-counterfeiting display layer to emit light by the wireless transmission module, determining the effectiveness of the anti-counterfeiting display layer; in the case where the chip information layer meets the preset condition, controlling the wireless transmission module to drive the anti-counterfeiting display layer; determining whether the anti-counterfeiting display layer emits light; in the case where the anti-counterfeiting display layer emits light, determining the effectiveness of the chip information layer and the anti-counterfeiting display layer; in the case where the anti-counterfeiting display layer does not emit light, in response to an operation of driving the anti-counterfeiting display layer to emit light by the wireless transmission module, determining the effectiveness of the anti-counterfeiting display layer.

[0031] The authentication method for the security document provided by this application can authenticate a security document with a chip information layer and an anti-counterfeiting display layer. During authentication, it is possible to first determine whether the chip information layer meets the preset conditions. For example, it is determined whether the chip information layer is legal. In the case where the chip information layer does not meet the preset conditions, it is determined that the chip information layer is invalid. At this time, the wireless transmission module can be manually controlled to drive the anti-counterfeiting display layer to emit light, thereby determining the effectiveness of the anti-counterfeiting display layer. On the contrary, in the case where the chip information layer meets the preset conditions, the wireless transmission module is controlled to drive the anti-counterfeiting display layer, and it is determined whether the anti-counterfeiting display layer emits light. In the case where the anti-counterfeiting display layer emits light, it is determined that the chip information layer and the anti-counterfeiting display layer are valid. In the case where the anti-counterfeiting display layer does not emit light, the wireless transmission module is manually controlled to drive the anti-counterfeiting display layer to emit light, thereby determining the effectiveness of the anti-counterfeiting display layer. This method can authenticate the information and perform anti-counterfeiting verification on the security document without setting a power supply inside the security document. This not only reduces the thickness of the security document, but also eliminates the need to replace the battery inside the security document, improving the service life of the security document. At the same time, since the authentication method for this security document authenticates the security document in any one of the technical solutions of the first aspect, this authentication method also has all the beneficial technical effects of the security document in any one of the technical solutions of the first aspect, which will not be elaborated here.

[0032] The third aspect of the present invention proposes an authentication device for a security document, which can authenticate the security document in any one of the technical solutions of the first aspect. The authentication device for the security document includes: at least one NFC authentication module and / or at least one UHF authentication module, and a wireless transmission module. The NFC authentication module and / or the UHF authentication module are used to authenticate the chip information layer; the wireless transmission module is used to drive the anti-counterfeiting display layer; the NFC authentication module and the UHF authentication module can control the wireless transmission module to drive; the wireless transmission module is driven after the NFC authentication module and / or the UHF authentication module issue an activation instruction, and the operating time of the wireless transmission module is greater than or equal to 2 seconds before receiving the next instruction; the horizontal relative positions of the antennas in the NFC authentication module and / or the UHF authentication module and the wireless transmission module are the same as the horizontal relative positions of the antennas of the chip information layer and the anti-counterfeiting display layer in the security document, so as to maximize the electromagnetic signal reception efficiency.

[0033] The authentication device for the security document provided by this application includes at least one NFC authentication module and / or at least one UHF authentication module, and a wireless transmission module. The NFC authentication module and / or the UHF authentication module can authenticate the chip information layer. The wireless transmission module can drive the anti-counterfeiting display layer.

[0037] In order to more clearly understand the above - mentioned objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0038] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0039] Next, refer to Figures 1 to 10 Describe a security document, an authentication method, and an authentication device thereof according to some embodiments of the present invention.

[0040] According to an embodiment of the first aspect of the present invention, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, a security document is proposed in the first aspect of the present invention, which includes a substrate 1, a chip information layer 2, and an anti - counterfeiting display layer 3. The chip information layer 2 is disposed within the substrate 1. The anti - counterfeiting display layer 3 is disposed within the substrate 1. The chip information layer 2 includes at least one NFC chip 22 and / or UHF chip 24. The anti - counterfeiting display layer 3 includes at least one light - emitting element 34, and the light - emitting element 34 can be driven by a wireless charging device meeting a preset power and transmission frequency and emit light. The preset power is less than or equal to 80W, and the transmission frequency is between 10KHz and 500KHz. The transmission frequency is preferably between 100KHz and 200KHz. The substrate 1 includes at least one of a card - type document and a multi - page document.

[0041] The security certificate provided by the present invention includes a substrate 1, a chip information layer 2 and an anti-counterfeiting display layer 3. The chip information layer 2 and the anti-counterfeiting display layer 3 are both arranged in the substrate 1.

It can be understood that since the security certificate provided by the present application includes a chip information layer 2 and an anti-counterfeiting display layer 3, the chip information layer 2 and the anti-counterfeiting display layer 3 can be used independently to achieve information authentication and anti-counterfeiting. In addition, the two can also be used in combination to generate linkage between the two, so that the chip information in the chip information layer 2 can be visible whether it is valid, and the authenticity of the security certificate can be determined after the chip information expires. For example, when using, the chip information layer 2 can be authenticated first, and when the authentication is passed, the light-emitting element 34 of the anti-counterfeiting display layer 3 is triggered to emit light, thereby performing anti-counterfeiting verification. When the authentication fails, it proves that the chip information layer 2 is invalid or has problems. At this time, the light-emitting element 34 of the anti-counterfeiting display layer 3 can be manually triggered to emit light for anti-counterfeiting verification, so that information authentication and anti-counterfeiting verification can be achieved only through the security document. At the same time, since the anti-counterfeiting display layer 3 set in this application is driven by a wireless charging device to emit light, this application does not need to set a power supply in the security document, which not only reduces the thickness of the security document, but also does not need to replace the battery in the security document, thereby improving the use time and convenience of the security document.

[0042] Among them, the preset power is less than or equal to 80W, the transmission frequency is between 10KHz-500KHz, preferably between 100KHz-200KHz, and can be a QI protocol standard.

During authentication, it can first judge whether the chip information layer meets the preset condition. For example, judge whether the chip information layer is legal. When the chip information layer does not meet the preset condition, determine that the chip information layer is invalid. At this time, the wireless transmission module can be manually controlled to drive the anti-counterfeiting display layer to emit light, so as to determine the effectiveness of the anti-counterfeiting display layer. On the contrary, when the chip information layer meets the preset condition, control the wireless transmission module to drive the anti-counterfeiting display layer, and determine whether the anti-counterfeiting display layer emits light. When the anti-counterfeiting display layer emits light, determine that the chip information layer and the anti-counterfeiting display layer are valid. When the anti-counterfeiting display layer does not emit light, manually control the wireless transmission module to drive the anti-counterfeiting display layer to emit light, so as to determine the effectiveness of the anti-counterfeiting display layer. This method can authenticate the information of the security document and verify anti-counterfeiting without setting a power supply in the security document, which not only reduces the thickness of the security document, but also does not require replacing the battery in the security document, improving the service life of the security document. At the same time, since the authentication method for this security document authenticates the security document in any technical solution of the first aspect, this authentication method also has all the beneficial technical effects of the security document in any technical solution of the first aspect, which will not be elaborated here.

[0075] Such as Figure 10As shown in the figure, the second aspect of the present invention proposes an authentication method for a security document, which can authenticate the security document in any of the technical solutions of the first aspect. The authentication method for the security document includes: S202, using a security chip authentication device to authenticate the legality of the chip information layer.

[0076] S204, after the system authenticates that the chip information layer is legal, turn on the wireless transmission module based on the QI protocol to drive the anti-counterfeiting display layer.

[0077] S206, after the authenticator or the system observes that the anti-counterfeiting display layer emits light, it can determine the effectiveness of the chip information layer and the anti-counterfeiting display layer.

[0078] S208, if the system authenticates that the chip information layer is invalid or illegal, do not turn on the wireless transmission module based on the QI protocol.

[0079] S210, when the authenticator observes that the anti-counterfeiting display layer does not emit light, the wireless transmission module can be manually turned on to drive the anti-counterfeiting display layer to verify the effectiveness of the anti-counterfeiting display layer.

[0080] The security chip authentication device here can be the authentication device for the security document described below.

[0082] The authentication device 6 for the security document provided by this application includes at least one NFC authentication module 62 and / or at least one UHF authentication module 64, and a wireless transmission module 66. The NFC authentication module 62 and / or the UHF authentication module 64 can authenticate the chip information layer 2. The wireless transmission module 66 can drive the anti-counterfeiting display layer 3. The NFC authentication module 62 and the UHF authentication module 64 can control the wireless transmission module 66 to perform driving. The wireless transmission module 66 is driven after the NFC authentication module 62 and / or the UHF authentication module 64 issues an enabling instruction, and the running time of the wireless transmission module 66 is greater than or equal to 2 seconds before receiving the next instruction. The horizontal relative positions of the antennas in the NFC authentication module 62 and / or the UHF authentication module 64 and the wireless transmission module 66 are the same as the horizontal relative positions of the antennas of the chip information layer 2 and the anti-counterfeiting display layer 3 in the security document, so as to maximize the electromagnetic signal reception efficiency. Since the authentication device 6 for the security document authenticates the security document in any of the technical solutions of the first aspect, therefore, this authentication device also has all the beneficial technical effects of the security document in any of the technical solutions of the first aspect, which will not be elaborated here.
