As shown in fig. 1, the present disclosure provides a security element 1 including a pattern layer 11, and a conductive pattern 111 and a non-conductive pattern 112 are disposed on the pattern layer 11. In a state where the conductive pattern 111 is in contact with the touch screen, the conductive pattern 111 can change capacitance distribution of the touch screen; in a state where the non-conductive pattern 112 is in contact with the touch screen, the non-conductive pattern 112 cannot change the capacitance distribution of the surface layer of the touch screen.
In one embodiment, the identification of the security element is performed using capacitive technology and through a touch screen. The number of the pattern layers 11 of the security element 1 may be one or more, and the number of the conductive patterns 111 and the non-conductive patterns 112 may be one or more. When the conductive pattern 111 contacts the touch screen, the surface capacitance distribution of the touch screen can be changed through the conductive pattern 111, so that the touch screen generates response; the non-conductive pattern 112 does not cause the touch screen to respond when it contacts the touch screen. The touch screen is set to an activated state in which touch point data can be recorded.
The touch screen can be various existing capacitive touch screens. For example, the capacitive touch screen is a four-layer composite glass screen, the inner surface and the interlayer of the glass screen are respectively coated with a layer of ito (indium Tin oxides) to form a capacitor, and four electrodes are led out from four corners of the capacitive touch screen.
When a finger of a person directly or a material with better conductivity and the like contacts the surface of the capacitive touch screen, a coupling capacitor is formed by the finger or the conductive material and a working surface due to a human body electric field, a small current is absorbed by the finger or the conductive material due to the fact that a high-frequency signal is connected to the working surface, the current respectively flows out of electrodes on four corners of the capacitive touch screen, theoretically, the current flowing through the four electrodes is proportional to the distance from the finger to the four corners of the capacitive touch screen, and the controller calculates the contact position of the conductive pattern and the surface of the screen through precise calculation of the proportion of the four currents to generate response.
The conductive pattern 111 is made of a material with good conductivity, and when the conductive pattern 111 contacts the capacitive touch screen, the conductive pattern 111 can change the capacitance distribution on the surface of the touch screen, so that the touch screen generates response.
When the non-conductive pattern 112 contacts the capacitive touch screen, since the conductivity of the material of the non-conductive pattern 112 contacting the surface of the capacitive touch screen is not high enough, the non-conductive pattern 112 and the surface of the capacitive touch screen cannot form an effective coupling capacitance, the high-frequency current on the surface of the capacitive touch screen cannot be changed, and the touch screen cannot respond.
One or more conductive patterns 111 and non-conductive patterns 112 may be simultaneously disposed on one pattern layer 11. The conductive pattern 111 and the non-conductive pattern 112 may be respectively disposed on different pattern layers 11. The conductive pattern 111 and the non-conductive pattern 112 have the same or similar color.
Various methods can be used to determine whether the conductive pattern 111 and the non-conductive pattern 112 are similar in color. For example, a first gray value of the color of the conductive pattern 111 is obtained, a second gray value of the color of the non-conductive pattern 112 is obtained, and if the difference between the first gray value and the second gray value is smaller than a preset difference threshold, the colors of the conductive pattern 111 and the non-conductive pattern 112 are determined to be similar.
In one embodiment, the conductive pattern 111 and the non-conductive pattern 112 may be on the same pattern layer and formed in the same process, with the same or similar color. The conductive pattern 111 and the non-conductive pattern 112 may be formed on different pattern layers sequentially in the same or different processes, and have the same or different appearance colors. For example, the conductive pattern 111 is formed before the non-conductive pattern 112.
The conductive pattern 111 and the non-conductive pattern 112 at least partially overlap, and the non-conductive pattern 112 may also cover the conductive pattern 111. The transparency of the conductive pattern 111 in the visible light range is greater than a transparency threshold, which may be a transparency of 10%, etc. For example, the conductive pattern 111 has a transparency of not less than 10% in the visible light range.
In one embodiment, the conductive pattern 111 and the non-conductive pattern 112 are on the same pattern layer, but formed by different processes, and have different colors, wherein the non-conductive pattern area is a transparent photo-curing adhesive, the transparent pattern with grooves is formed on the transparent substrate after coating and nano-imprinting, the conductive pattern area is silver paste, the non-conductive pattern is filled into the grooves in a coating or blade coating manner after the non-conductive pattern is formed, the non-transparent conductive pattern is formed in the grooves, and the transparency of the anti-counterfeiting element is still not less than the transparency threshold.
In one embodiment, the present disclosure provides a security article comprising a security element as in any of the embodiments above. The security article is a foldable or rollable security article, including securities, documents, banknotes, etc.
FIG. 2 is a schematic flow diagram of one embodiment of a detection method for a security article according to the present disclosure, as shown in FIG. 2:
In one embodiment, the detection standard information of the anti-counterfeiting element to be detected is preserved in advance, and the contact point information of the conductive pattern on the touch screen can be determined through the touch screen by using the capacitance information. Partially folding and/or curling the detected security article prior to detection; upon detection, one or more patterned layers (areas) on the security article are pressed against the touch screen simultaneously or sequentially according to the detection method prompted by the device.
In the state where the forgery prevention element is in contact with the touch screen, various methods can be employed to acquire data concerning changes in capacitance distribution of the touch screen. For example, when the anti-counterfeiting element is in contact with a screen, only the area with the conductive image-text can enable the corresponding contact position to generate current change in the whole contact area, so that touch response is caused; the non-conductive areas do not respond as described above and therefore data of the change in capacitance at the contact location can be recorded by the device for determination.
The security element is flexible and rollable, wherein the distribution and communication of the conductive patterns is determined according to the design. The detection method for the anti-counterfeiting element comprises the following steps: the finger does not directly press the screen; when in detection, the two sides of the anti-counterfeiting element are held by hands, the anti-counterfeiting element is curled, and at least one position of a finger is contacted with one part of the conductive image-text in the element, so that the micro-current of a human body is conducted to the communication area of the whole conductive image-text; and then the curled anti-counterfeiting element enables specific pictures and texts in the anti-counterfeiting element to be in contact with the screen according to the prompt given on the screen.
If the conductive images and texts of the conductive circuits need to be detected respectively, the equipment prompts in sequence to change the contact position of the finger and the anti-counterfeiting element or the contact image and text position of the anti-counterfeiting element and the screen.
The touch screen can be set to an activated state capable of recording contact data, and response data of the conductive pattern on the touch screen, which is acquired by the capacitive sensor, is acquired, namely capacitance distribution change data of the conductive pattern on the touch screen.
In step 202, contact information corresponding to the conductive pattern is determined according to the capacitance distribution change data.
In one embodiment, the conductive pattern can change capacitance distribution of the touch screen and can cause capacitance change when the anti-counterfeiting element is in contact with the touch screen, and the capacitance sensor collects corresponding electrical signals and converts the electrical signals into contact information corresponding to the conductive pattern.
In one embodiment, conductive pattern feature data which should be possessed by the security article is stored in advance in the detection device with the touch screen as the check standard information. And comparing the collected contact information with the inspection standard information to identify the authenticity of the safe article.
The inspection standard information comprises standard pattern information, and the contact information comprises detection pattern information corresponding to the conductive pattern; the standard pattern information and the detection pattern information include relative positions and distances between the contacts, contact areas, change information of charge signal distribution, and corresponding pressure value information, and the like. For example, the standard pattern information and the detection pattern information include information on relative positions and distances between different contacts, a change in current signal distribution, a change in charge signal distribution, a pressure value, a contact area, and the like. If the detection pattern information is the same as the detection pattern information, determining the anti-counterfeiting element as a true anti-counterfeiting element; and if the detection pattern information is different from the detection pattern information, determining that the anti-counterfeiting element is a false anti-counterfeiting element.
Various methods can be used to obtain the standard pattern information and the detection pattern information. For example, when a touch signal is sensed by a screen of the capacitive touch screen, coordinate values (x, y) of a touch point in the screen can be recorded, so that when multiple touch points are touched, the relative position and distance of each point can be calculated; by acquiring basic data in the capacitance sensor by software, such as the coordinates and number of pixels in which the charge distribution changes, the pressure value of the pressure sensor in the coordinates, and the like, information such as the contact area can be calculated.
During verification, detection prompt information for the anti-counterfeiting element is generated, and the detection prompt information can be displayed in a dialog box or other forms. The detection prompt message comprises: and pressing a plurality of pattern layers of the anti-counterfeiting element on the touch screen simultaneously or sequentially to obtain the information. The user can contact the anti-counterfeiting element of the security article with the touch screen by adopting a corresponding method according to the detection prompt information displayed by the dialog box and the like.
As shown in fig. 3, the anti-counterfeit element of the security article to be detected is pressed on the touch screen in the activated state by a finger, the capacitance distribution change data of the touch screen can be read, the distribution situation of the conductive patterns in the anti-counterfeit element is calculated based on the capacitance distribution change data, and the contact information of the finger region with a larger pressure value is removed, so that the authenticity can be identified. Various methods can be used to calculate the distribution of the conductive patterns in the security element. For example, according to the number of contacts in the capacitive screen, the position and the area of each contact, the trend of the conductive image-text in the area where the element is in contact with the screen can be drawn, similar to the trend of the current.
As shown in fig. 4, the anti-counterfeit element of the security article to be detected is pressed on the touch screen in the activated state, and slides, so that the capacitance distribution of the touch screen and the real-time change data of the contact area can be read, and the contact information of the finger area with a larger pressure value is removed, thereby calculating the distribution of the conductive patterns in the anti-counterfeit element, and performing authenticity identification.
As shown in fig. 5, after the security article to be detected is curled by one hand, the anti-counterfeiting element is pressed on the touch screen in an activated state, so that capacitance distribution change data of the touch screen can be read, and the distribution situation of the conductive patterns in the anti-counterfeiting element is calculated based on the capacitance distribution change data, thereby performing authenticity identification.
As shown in fig. 6, two hands contact two ends of the security article to be detected, and the anti-counterfeiting element is pressed on the touch screen in an activated state, so that capacitance distribution change data of the touch screen can be read, and the distribution situation of the conductive patterns in the anti-counterfeiting element is calculated based on the capacitance distribution change data, thereby performing authenticity identification.
