Detailed Description

In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.

Methods and apparatuses for authenticating an anti-counterfeit paper sheet, electronic devices, and readable storage media according to some embodiments of the present invention are described below with reference to fig. 1 to 16.

Example 1:

as shown in fig. 1, the embodiment provides an anti-counterfeiting paper authentication method, which includes the following steps:

step S102, controlling the light source to be started, determining the relative position of the image acquisition device and the anti-counterfeiting paper as a first relative position, and acquiring a first image of the anti-counterfeiting paper under the condition that the shooting angle of the image acquisition device when shooting the anti-counterfeiting paper is in a reflective state, wherein the first image comprises at least one first variable image-text and at least one second variable image-text;

step S104, obtaining the ambient brightness, and determining the environment type according to the ambient brightness;

step S106, when the environment type is the first type, the light source is controlled to be turned off, the relative position of the image acquisition device and the anti-counterfeiting paper is determined to be a second relative position, and when the shooting angle of the image acquisition device for shooting the anti-counterfeiting paper is in a light transmission state, a second image of the anti-counterfeiting paper is acquired, wherein the second image at least comprises a first variable image text;

Step S108, comparing the first image with the first preset feature, comparing the second image with the second preset feature, and judging that the authentication result of the anti-counterfeiting paper is true under the condition that the first image is identical to the first preset feature and the second image is identical to the second preset feature.

In this embodiment, a first set of parameters of a supplemental light source and an image acquisition device in the handheld electronic device are set, and a user is guided to move the image acquisition device or the anti-counterfeit paper so that the supplemental light source and the image acquisition device or the anti-counterfeit paper are located at a first relative position.

In particular, the supplemental light source may provide illumination when authenticating the security paper. By setting the first set of parameters, the supplemental light source may be set to an on state. At this time, the supplement light source irradiates the anti-counterfeiting paper, so that the anti-counterfeiting paper is in a reflective state.

Specifically, when the image acquisition device and the anti-counterfeiting paper are positioned at the first relative position, the image acquisition device can shoot the whole anti-counterfeiting paper so as to ensure that the whole anti-counterfeiting paper can be acquired, and avoid the condition of identification errors caused by incomplete image acquisition.

The first relative position may be a position at which the vertical distance between the security paper and the image pickup device is fixed to a fixed value, or a position at which the vertical distance is within a range of values. The anti-counterfeiting paper and the image acquisition device can be positioned at more accurate positions by setting the anti-counterfeiting paper and the image acquisition device to be a fixed numerical value. However, in use, a fixed numerical limitation is too severe and is not easily achieved due to errors, so that the numerical limitation is set to a numerical range, and the numerical limitation is more practical in use.

When the image acquisition device or the anti-counterfeiting paper is moved, a contour map of the anti-counterfeiting paper is arranged on a display screen of the handheld electronic device. The image acquisition device or the anti-counterfeiting paper is moved so that the anti-counterfeiting paper is completely positioned in the outline drawing, and the fact that the vertical distance between the image acquisition device and the anti-counterfeiting paper is within the numerical range is indicated.

In this embodiment, whether the shooting angle is in a reflective state is determined by using the handheld electronic device, and when the shooting angle is in the reflective state, a first image of the anti-counterfeiting paper is shot.

Specifically, after the first group of parameters are set, the supplementary light source is turned on to provide illumination, and the anti-counterfeiting paper at the moment can be in a light reflection state. The handheld electronic equipment judges the state of the anti-counterfeiting paper at the moment according to the set first group of parameters, and when the anti-counterfeiting paper is confirmed to be in the reflective state, the image acquisition device is controlled to acquire reflective state image information (namely a first image) of the anti-counterfeiting paper, wherein the first image comprises a first variable image-text and a second variable image-text.

In this embodiment, based on the environment type being the first type, a second set of parameters of the supplemental light source and the image acquisition device in the handheld electronic device are set, so as to guide the user to move the image acquisition device or the anti-counterfeit paper, and the supplemental light source and the image acquisition device are located at a second relative position.

Specifically, by setting the second set of parameters, the supplemental light source may be set to an off state. At this time, the supplementary light source is turned off, and the anti-counterfeiting paper is in a brighter light-transmitting environment.

Specifically, the first relative position and the second relative position enable the vertical distance between the anti-counterfeiting paper and the image acquisition device to be the same fixed value, the anti-counterfeiting paper and the image acquisition device are used for obtaining first variable graphics with the same size in a light reflecting state and a light transmitting state, meanwhile, the anti-counterfeiting paper can be completely shot by the image acquisition device, and a user is guided to realize through setting an anti-counterfeiting paper outline map in a screen.

In this embodiment, the handheld electronic device is used to determine whether the shooting angle is in a light-transmitting state, and when the shooting angle is in the light-transmitting state, a second image of the anti-counterfeiting paper is shot.

Specifically, after the second group of parameters are set, the supplementary light source is turned off, and at the moment, the external light brightness is high, and the anti-counterfeiting paper is in a light-transmitting state. The handheld electronic equipment judges the state of the anti-counterfeiting paper at the moment according to the set second group of parameters, and when the anti-counterfeiting paper is confirmed to be in a light transmission state, the image acquisition device is controlled to acquire light transmission state image information (namely a second image) of the anti-counterfeiting paper, wherein the second image comprises a first variable image-text.

In this embodiment, the first type is a white day type, and the second type is a night type.

In some embodiments, the first changeable graphic comprises a coding pattern comprising a number or a two-dimensional code. Specifically, the first changeable graphics includes, but is not limited to, a number, a two-dimensional code, or other apparent form of coding pattern.

In this embodiment, the number and the two-dimensional code are a set of numerical values, so that the anti-counterfeiting paper can be encoded through the number or the two-dimensional code, so that the anti-counterfeiting paper has uniqueness, and the anti-counterfeiting performance of the anti-counterfeiting paper is enhanced. The first variable image-text adopts a number or a two-dimensional code, so that the anti-counterfeiting paper has traceability during authentication.

In some embodiments, the second changeable graphic comprises a printed number, a two-dimensional code, a physical feature. Specifically, the anti-counterfeiting paper contains a second variable image and text, and the second variable image and text can be one or more of a printed number, a two-dimensional code and a random physical characteristic.

In this embodiment, the printed number and the two-dimensional code are a set of numerical values, so that the anti-counterfeiting paper can be encoded through the number or the two-dimensional code, so that the anti-counterfeiting paper has uniqueness, and the anti-counterfeiting performance of the anti-counterfeiting paper is further enhanced. The second variable image-text adopts a printed number or a two-dimensional code, so that the traceability of the anti-counterfeiting paper can be further enhanced, and the identification of the anti-counterfeiting paper is facilitated.

In this embodiment, the encoded content is stored in the handheld electronic device, so that the encoded content can be directly used out of the network; and stored in a cloud database, and network connection is needed when the cloud terminal is used.

In some embodiments, the visual effect of the first changeable graphic on the display as it changes in a particular period is preset in the handheld electronic device.

In this embodiment, the visual effect preset in the handheld electronic device can facilitate comparison, which is more beneficial to identifying the authenticity of the anti-counterfeiting paper.

According to the embodiment, the identification accuracy of the anti-counterfeiting paper can be improved by verifying the unique information of the first variable graphics and the second variable graphics. The phenomenon of false identification of the anti-counterfeiting paper caused by subjective judgment influence of different users on the observation effect can be avoided.
