Description

Technical field

Background technique

Barcodes and QR codes have been widely adopted to encode information. When these barcodes and QR codes are scanned with a specific device or software, the corresponding information is identified. However, the recognition distance between the barcode and the two-dimensional code is very limited. For example, for a two-dimensional code, when scanning with a mobile phone camera, the phone must typically be placed at a relatively short distance, typically about 15 times the width of the two-dimensional code. Therefore, for long-distance recognition (for example, 200 times the width of the two-dimensional code), barcodes and two-dimensional codes are usually not implemented, or very large barcodes and two-dimensional codes must be customized, but this will bring about an increase in cost. And in many cases it is impossible to achieve due to various other restrictions. Moreover, barcodes and QR codes are also easily copied and replaced, and the security is not good, and it is not suitable for scenarios with high security requirements.

Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings, in which FIG. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In one embodiment of the invention, an optical communication device is provided that is capable of transmitting different information by emitting different lights. The optical communication device is also referred to herein as a "light tag" and both are used interchangeably throughout this application. The optical communication device includes at least one light source and a controller for controlling different lights emitted by the light source to convey different information.

The controller can cause the light source to emit different light by changing the properties of the light emitted by the light source. The property of the light may be any property that the optical imaging device (eg, CMOS imaging device) can perceive; for example, it may be an attribute of the human eye that is perceived by the intensity, color, wavelength, etc. of the light, or other attributes that are not perceptible to the human eye. For example, the intensity, color or wavelength of the electromagnetic wavelength outside the visible range of the human eye changes, or any combination of the above properties. Thus, a change in the properties of light can be a single property change, or a combination of two or more properties can change. When the intensity of the light is selected as an attribute, it can be achieved simply by selecting to turn the light source on or off. In the following, for the sake of simplicity, the light source is turned on or off to change the properties of the light, but those skilled in the art will appreciate that other ways to change the properties of the light are also possible.

Various forms of light sources can be used in the optical tag as long as one of its properties that can be perceived by the optical imaging device can be varied at different frequencies. Various common optical devices can be included in the light source, such as a light guide plate, a soft plate, a diffuser, and the like. For example, the light source may be an LED light, an array of a plurality of LED lights, a display screen or a part thereof, and even an illuminated area of light (for example, an illuminated area of light on a wall) may also serve as a light source. The shape of the light source may be various shapes such as a circle, a square, a rectangle, a strip, an L, or the like.

In one embodiment, the controller of the optical tag can control the properties of the light emitted by each source to communicate information. For example, "0" or "1" of binary digital information can be represented by controlling the turning on and off of each light source such that multiple light sources in the optical tag can be used to represent a sequence of binary digital information. As will be appreciated by those skilled in the art, each light source can be used not only to represent a binary number, but also to represent data in ternary or larger hexadecimal. For example, by setting the intensity of the light emitted by the light source to be selected from three or more levels, or by setting the color of the light emitted by the light source to be selected from three or more colors, Even by using a combination of intensity and color, each light source can represent data in ternary or larger hexadecimal. Therefore, the optical tag of the present invention can significantly increase the data encoding density compared to the conventional two-dimensional code.

In still another embodiment, the controller of the optical tag can control the light source to change the properties of the light it emits at a certain frequency. Therefore, the optical tag of the present invention can represent different data information at different times, for example, different. A sequence of binary digital information. Thus, when the optical tag of the present invention is continuously photographed using an optical imaging device (for example, at a rate of 30 frames per second), each frame of the image can be used to represent a set of information sequences, thereby comparing to a conventional static The QR code can further significantly increase its data encoding density.

In an embodiment of the present application, an optical label can be imaged using an optical imaging device or an image capture device that is common in the art, and the transmitted information, such as a binary data 1 or a data 0 information sequence, is determined from each frame of image to achieve light. Information transfer from the label to the optical imaging device. The optical imaging device or image acquisition device may include an image acquisition component, a processor, a memory, and the like. The optical imaging device or image acquisition device may be, for example, a smart mobile terminal having a photographing function, including a mobile phone, a tablet, smart glasses, etc., which may include an image capture device and an image processing module. The user visually finds the optical tag within a range of distance from the optical tag, and scans the optical tag by performing the information capture and interpretation process by causing the mobile terminal imaging sensor to face the optical tag. When the controller of the optical tag controls the light source to change the attribute of the light emitted by the light source at a certain frequency, the image acquisition frequency of the mobile terminal can be set to be greater than or equal to twice the frequency of the attribute conversion of the light source. The process of identifying and decoding can be completed by performing a decoding operation on the acquired image frame. In an embodiment, in order to avoid duplication, omission, and the like of the image frame, the serial number, the check digit, the time stamp, and the like may be included in the information transmitted by the optical tag. A start frame or an end frame may be given in a plurality of image frames as needed, or both, for indicating a start or end position of a complete period of the plurality of image frames, the start frame or the end frame may be It is set to display a particular combination of data, for example: all 0s or all 1s, or any special combination that will not be the same as the information that may actually be displayed.

Taking a CMOS imaging device as an example, when a continuous multi-frame image of a light source is captured by a CMOS imaging device, it can be controlled by a controller such that a switching time interval between operating modes of the light source is equal to a full frame imaging time of the CMOS imaging device. Length, thereby achieving frame synchronization of the light source with the imaging device. Assuming that each light source transmits 1 bit of information per frame, for a shooting speed of 30 frames per second, each light source can deliver 30 bits of information per second, with an encoding space of 2 ³⁰ , which can include, for example, an initial Frame tag (frame header), optical tag ID, password, verification code, URL information, address information, time stamp, or a different combination thereof. The order relationship of the above various kinds of information can be set in accordance with a structuring method to form a packet structure. Each time a complete packet structure is received, it is considered to obtain a complete set of data (a packet), which can be read and verified. Table 1 presents an example packet structure in accordance with one embodiment of the present invention:

Compared with the conventional two-dimensional code, the optical label according to the embodiment of the present invention transmits information by emitting different light, which has the advantages of long distance, visible light condition requirement, strong directivity, and positionability, and is transmitted by the optical label. The information can change rapidly over time, providing a large information capacity. Therefore, optical tags have greater information interaction capabilities, which can provide great convenience for users and businesses. In order to provide corresponding services to users and merchants based on optical tags, each optical tag is assigned a unique identifier (ID) for uniquely identifying or identifying by the manufacturer, manager, user, etc. of the optical tag. Light label. In many cases, an optical tag needs to publish its identifier, and the user obtains its identifier by scanning the optical tag to access the service provided based on the optical tag. During this period, there may be various security risks caused by the interception, forgery or replacement of the identification information issued by the optical label.

FIG. 1 illustrates an optical tag anti-counterfeiting system including an optical tag 30 and an authentication server 40 in accordance with an embodiment of the present invention. The optical tag 30 typically includes a controller and a light source for controlling the light source to emit different light to convey different information. The user 10 can perform image acquisition on the optical tag 30 using the image capture device 20 (eg, a cell phone) to obtain information transmitted by the optical tag 30, and authenticate the validity of the optical tag 30 by the authentication server 40. The image capture device 20 typically has a communication function.

In order to prevent the optical tag from being illegally forged or replaced, the optical tag 30 fills the identification information by its controller according to a preset filling rule each time its identification information (hereinafter also referred to as an optical tag identifier) is issued. The filled identification information is then input as an input to a preset transformation function, and then the controller controls the light source to display the output value of the transformation function. The preset fill rules and transformation functions are only visible to the optical tag 30 and the authentication server 40, but are kept secret for image acquisition devices, users, merchants, and other optical tag-based service providers. In this embodiment, by filling the identification information, the optical tag can present different encoding information each time the identification information is released, thereby converting the static and unchanged identifier information into dynamically changing information to prevent Forgery or substitution of optical labels. For example, the identification information may be filled with randomly generated content (eg, a random number) by the optical tag controller, and the content may be added before, after, or in some manner with the identification information. Preferably, the current time information when the identification information is posted may be filled in before, after or in a certain manner with the identification information, so that the optical label displays different content each time the identification information is issued.

In this embodiment, the specific form of the transformation function is not limited, and any function or transformation rule that causes the filled identification information to be changed may be employed. For example, the order of each element in the filled identification information is scrambled according to a certain rule, and some positions in the filled identification information are reversed and the like. Preferably, the existing various symmetric encryption or asymmetric encryption algorithms may be selected to encrypt the filled identification information. For example, the optical tag encrypts the padded identification information with its key, and the authentication server can decrypt the received information with the same key. In an embodiment of the invention, only the authenticator (e.g., authentication server 40) that knows the transformation function can inverse transform the received information to obtain the filled identification information of the optical tag, and further from the filled identification. The identification information is extracted from the information to verify the legality of the optical label. Let f denote any transform function, ID denotes the optical tag identifier, and the controller controls the information sent by the corresponding light source to be e=f (ID+padding information) each time the optical tag issues its identifier. After the verification party processes the received information e with the inverse transform function f ^-1 corresponding to f, the optical tag identifier ID = f ^-1 (e) - padding information can be obtained.

In this embodiment, all optical tags share the same transform function. The authentication server 40 processes the received information using a predetermined inverse transform function corresponding to the transform function of the optical tag to obtain identification information of the optical tag. In other embodiments, a portion of the optical label may be assigned a transform function and the other optical labels may be assigned a different transform function. For example, all optical tags that are in the same region or belong to the same service or the same organization can be assigned the same transformation function, while optical tags that are in different regions or belong to different services or organizations share different transformation functions. In yet another embodiment, each optical tag can also be assigned a unique transform function. Correspondingly, for the authentication server 40, only when the transform function used by the optical tag is known, the received information can be inversely transformed to obtain the identification information of the optical tag. Therefore, in still another embodiment, the optical tag 30 also issues an identifier of a conversion function (hereinafter simply referred to as a function identifier) used by the optical tag 30 for each time, such as the authentication server 40, while releasing its identification information. The verifier of the verifier selects the corresponding inverse transform function according to the function identifier. For example, in the data packet structure given in Table 1, the data packet sent by the optical label when the identity information is advertised may include a frame header, an attribute field, a data field, a parity bit, and a frame tail. The attribute field includes a function selection bit, that is, an identifier of a transformation function used by the optical label; and the data field includes an output value processed by the transformation function by using the filled identification information as an input.

With continued reference to FIG. 1, in some embodiments, the authentication server 40 can have an inverse transform function corresponding to one or more transform functions for the optical tag and assign a unique function to each transform function and its corresponding inverse transform function. Identifier. The above information can be stored, for example, in a function table as shown in Table 2.

When the user 10 collects an image of the optical tag using the image acquisition device 20 and decodes the image, the information transmitted by the optical tag can be obtained. The user 10 can pass the information to the authentication server 40 via the image capture device 20. When the authentication server 40 receives the information from the image collection device 20, the corresponding inverse transformation function may be selected by the function identifier in the information to inversely transform the information in the data field, and based on the set filling rule. The optical tag identifier is extracted from the information obtained by the inverse transform. If the optical tag identifier is an identifier of the registered optical tag, the verification is passed, the confirmation information is returned, or the service based on the optical tag is provided.

In embodiments where the padding information is current time information, the legitimacy of the optical tag can be further verified by padding the information. For example, after the authentication server 40 extracts the padded time information from the received information, the time information is compared with the current time of the authentication server 40, if the difference between the two exceeds a certain threshold (for example, a preset optical tag) When the identifier information is sent, the authentication server determines that the received information is invalid and requests to resend the authentication information. This can further prevent the optical tag from being forged or replaced.

In yet another embodiment, two or more transformation functions can be assigned to each optical tag. Each time the optical tag issues its identification information, it can randomly select one of the transformation functions or alternately select the corresponding transformation function in a certain order to transform its optical label information, so that the optical label is updated each time its identification information is issued. Different encoding information is sent. Preferably, each time the optical tag 30 issues its identification information, its controller fills the identification information according to the set filling rule (for example, populates the current time information) and selects a transformation function from a plurality of transformation functions, and then The filled identification information is provided as input to the selected transformation function, and then the controller controls the light source to display the output value of the transformation function and the function identifier of the selected transformation function.

2 is a flow chart showing an optical tag anti-counterfeiting method in accordance with an embodiment of the present invention. The anti-counterfeiting method mainly includes steps 201 to 208. More specifically, in step 201, when the optical tag 30 issues its identification information, its controller fills the identification information according to a preset filling rule. Preferably, the content filled each time is different. By filling the identification information, the optical label can present different encoding information each time the identification information is released, thereby converting the static and unchanged identifier information into dynamically changing information to prevent forgery of the optical label or Alternative. For example, the identification information may be filled with randomly generated content (eg, a random number) by the optical tag controller, and the content may be added before, after, or in some manner with the identification information. Preferably, the current time information when the identification information is posted may be filled in before, after or in a certain manner with the identification information, so that the optical label displays different content each time the identification information is issued. The preset fill rules are only visible to the optical tag 30 and the authenticator (eg, the authentication server 40), but are kept secret for the image capture device, users, merchants, and other optical tag-based service providers.

At step 202, the filled identification information is input as an input and supplied to a preset transformation function for conversion. Here, the specific form of the transformation function is not limited, and any function or transformation rule that causes the filled identification information to be changed may be employed. For example, the order of each element in the filled identification information is scrambled according to a certain rule, and some positions in the filled identification information are reversed and the like. Preferably, the existing various symmetric encryption or asymmetric encryption algorithms may be selected to encrypt the filled identification information. Only the authenticator (for example, the authentication server 40) who knows the transformation function can inversely transform the received information to obtain the filled identification information of the optical label, and further extract the identification information from the filled identification information, thereby Verify the legality of the optical label.

Next, in step 203, the controller controls the light source to display the output value of the transformation function, thereby completing the issuance of the identification information. In still another embodiment, the controller of the optical tag 30 controls the source to display the output value of the transform function while also displaying the identifier of the transform function used by it for identification by a verifier such as the authentication server 40. To select the corresponding inverse transform function. In an embodiment in which two or more transform functions are assigned to each optical tag, the optical tag may randomly select any one of the transform functions or alternately select the corresponding transform function in a certain order each time the identification information is issued. The optical tag information is transformed such that the optical tag transmits different encoding information each time its identification information is issued. In yet another embodiment, the above-described padding or transformation may not be performed by the optical tag or its controller, but may be by other devices capable of communicating with the optical tag 30 (eg, for providing the optical tag 20 with a server to display information) Filling and transforming the identification information, and then providing the transformed information to the optical tag for presentation or distribution.

As described above, the user 10 can collect the information conveyed by the optical tag 30 through the image capture device 20 (step 204). If the user 10 needs to know and/or verify the identity of the optical tag when accessing the service provided based on the optical tag, or the user 10 has doubts about the authenticity of the optical tag 30, the information collected by the image capturing device 20 may be sent to The authentication server performs verification (step 205). In an embodiment where all optical tags share the same transform function, the authentication server 40 processes the received information using an inverse transform function corresponding to the transform function of the optical tag, and inversely transforms it (step 206), and then The padding information is removed from the inversely transformed information based on a preset padding rule to obtain identification information of the optical tag (step 207). Next at step 208, the authentication server determines whether the obtained identification information of the optical tag is a valid or registered identifier. For example, the corresponding identifier can be looked up in the registered optical tag database, and if found, the identifier is determined to be a valid optical tag identifier. The authentication server may return a confirmation message that the verification is passed to the requesting party (eg, user 10) that requires verification. The identifier of the optical tag may be included in the confirmation information. Conversely, if a matching identifier is not found in the optical tag database, a risk alert is sent to the user indicating that the optical tag may be illegal or there is a risk of being forged.

In some embodiments in which different optical functions are assigned different transform functions or the same optical label uses different transform functions, when the authentication server 40 receives the information collected by the image acquisition device 20, the corresponding inverse transform function is selected by the function identifier. The information in the data field is inversely transformed, and the optical tag identifier is extracted from the inversely transformed information based on the set filling rule. If the optical tag identifier is an already registered optical tag, the verification passes, and the confirmation information is returned. And/or providing identification information of the optical tag to perform subsequent services according to the ID. In embodiments where the padding information is current time information, the legitimacy of the optical tag can be further verified by padding the information. For example, after the authentication server 40 extracts the padded time information from the received information, the time information is compared with the current time of the authentication server 40, if the difference between the two exceeds a certain threshold (for example, a preset optical tag) When the identifier information is sent, the authentication server determines that the received information is invalid and requests to resend the authentication information. This can further prevent the optical tag from being forged or replaced.

The anti-counterfeiting method of the present invention can be applied to any optical tag (or light source) that can be used to transmit information. For example, the anti-counterfeiting method of the present invention can be applied to a light source that transmits information through different stripes based on a rolling shutter effect of CMOS (for example, the optical communication device described in Chinese Patent Publication No. CN104168060A), and can also be used in, for example, the patent CN105740936A.
