Before the present invention is described in detail, it should be noted that like components are represented by like numerals throughout the following description.
Referring to fig. 1, an embodiment of a self-anti-counterfeiting multi-dimensional barcode generating and verifying system 100 of the present invention mainly includes a self-anti-counterfeiting multi-dimensional barcode generating device 10 (hereinafter referred to as multi-dimensional barcode generating device 10) and a self-anti-counterfeiting multi-dimensional barcode verifying device 20 (hereinafter referred to as multi-dimensional barcode verifying device 20).
The multi-dimensional barcode generating device 10 shown in fig. 2 is used to implement the multi-dimensional barcode generating method for self-anti-counterfeiting of the present invention, and mainly includes a storage unit 101, a processing unit 102 electrically connected to the storage unit 101, and an output unit 103. The multi-dimensional barcode generating device 10 can be any electronic device with computer-related functions, such as a personal computer, a notebook computer, a tablet computer, a smart phone, a smart watch, an authentication platform disposed on a network, an electronic device electrically connected to a hardware carrier, such as a smart card, or an electronic device with a chip (e.g., the processing unit 102 of the embodiment) capable of generating a multi-dimensional barcode, but is not limited thereto. In an embodiment, as shown in step S31 of fig. 3, the multi-dimensional barcode generating apparatus 10 stores an initial data 40 to be made into a (self-counterfeit-proof) multi-dimensional barcode and at least one authentication information 41 in the storage unit 101, where the authentication information 41 may be a picture, an audio, a text, a number, a comparison priority, or any combination thereof, and in this embodiment, as shown in fig. 4, the authentication information 41 is an example of a picture. Preferably, the initial data 40 and the authentication information 41 can be provided by the same third party device (not shown), or provided by different third party devices, or the initial data 40 is from the third party device, and the authentication information 41 is generated by the processing unit 102 itself or according to the initial data 40, but not limited thereto.
Next, as step S32 of fig. 3, the processing unit 102 of the multi-dimensional barcode generating apparatus 10 retrieves the initial data 40 and the authentication information 41 from the storage unit 101, and encodes the initial data 40 and the authentication information 41 according to a specific encoding rule, such as QR code encoding or other special encoding rules, to generate a multi-dimensional barcode 5 as shown in fig. 5, wherein the multi-dimensional barcode 5 includes a barcode area 50 and at least one verification area 51, the barcode area 50 includes a barcode 501, and the encoded initial data 40 and the authentication information 41 are hidden in the barcode 501; the verification area 51 is located in the barcode area 50, and the verification area 51 includes a verification message 511, the verification message 511 is related to the authentication message 41, that is, the verification message 511 includes, for example, a picture, a character, a number, a barcode or any combination thereof related to the authentication message 41, and in the embodiment, the verification message 511 is a picture as an example. Specifically, the processing unit 102 can generate the verification information 511 (picture) located in the verification area 51 according to the authentication information 41 (picture).
In various embodiments, to enhance the security of the information, the processing unit 102 may further encrypt the initial data 40 and the authentication information 41 at least once by using at least one encryption algorithm to generate an encrypted data, and then encode the encrypted data to generate the barcode 501 in the barcode area 50.
Then, as shown in step S33 of fig. 3, the processing unit 102 of the multi-dimensional barcode generating apparatus 10 can output the multi-dimensional barcode 5 generated by the multi-dimensional barcode generating apparatus 10 to the output unit 103 (display screen) for display through the output unit 103, for example, a display screen of the multi-dimensional barcode generating apparatus 10, as shown in fig. 6. Preferably, the processing unit 102 can also output the multi-dimensional bar code 5 to the third party device providing the initial data 40, so that the multi-dimensional bar code 5 can be applied to various fields using multi-dimensional bar codes related to the initial data 40, such as tickets, securities, advertisements, commodities, online transactions, and the like.
Referring to fig. 7, the multi-dimensional barcode verification apparatus 20 is used for verifying the (self-counterfeit-proof) multi-dimensional barcode generated by the multi-dimensional barcode generation apparatus 10 to implement the self-counterfeit-proof multi-dimensional barcode verification method of the present invention, and mainly includes a processing unit 201, and an output unit 202 and a capturing unit 203 electrically connected to the processing unit 201. The multi-dimensional barcode verification apparatus 20 may be a barcode capture device or an electronic apparatus with barcode capture function, such as a smart phone or a tablet computer, but not limited thereto. Therefore, as shown in step S81 of fig. 8, the capturing unit 203 can capture (e.g., scan or read) the multi-dimensional barcode 5 displayed on an object, or capture (e.g., scan or read) the multi-dimensional barcode 5 as shown in fig. 6, so as to obtain an image of the multi-dimensional barcode 5 and transmit the image to the processing unit 201, and then, as shown in step S82 of fig. 8, the processing unit 201 receives the image, and parses the multi-dimensional barcode 5, for example, decodes the barcode 501 in the barcode area 50 of the image, so as to obtain an encoded data including the initial data 40 and the authentication information 41, and obtains the authentication information 511 in the authentication area 51 of the multi-dimensional barcode 5. In addition, if the encoded data obtained by the processing unit 201 decoding the barcode 501 is the encrypted data, the processing unit 201 further decrypts the encoded data by using at least one decryption algorithm corresponding to the at least one encryption algorithm to obtain the initial data 40 and the authentication information 41.
Then, as in step S83 of fig. 8, the processing unit 201 determines whether the authentication information 41 and the verification information 511 are both related, for example, the processing unit 201 performs image recognition on the verification information 511 according to the authentication information 41, that is, if the authentication information 41 is a pattern, the processing unit 201 compares whether the pattern images of the authentication information 41 and the verification information 511 are consistent or corresponding, to determine whether the authentication information 41 is correlated with the verification information 511, and if so, as shown in step S84 of fig. 8, the processing unit 201 outputs a first determination result, such as displaying words such as successful authentication, alternatively, as shown in fig. 9, the authentication information 41 and the first determination result (i.e. word eye such as successful authentication) are displayed, so that the user can easily determine with naked eyes whether the authentication information 41 matches or corresponds to the verification information 511 in the multi-dimensional barcode 5. If not, the processing unit 201 outputs a second determination result, such as unsuccessful authentication, through the output unit 202, as shown in step S85 of fig. 8. It should be noted that, the determination of whether the authentication information 41 is related to the verification information 511 can be performed by means of string comparison, audio comparison, template comparison, feature point comparison (e.g., rootshift, SUFT), etc., but not limited thereto, so that the user can determine whether the multi-dimensional barcode 5 is tampered according to the determination result, thereby achieving the purpose of verifying the authenticity of the multi-dimensional barcode 5 and the anti-counterfeit of the multi-dimensional barcode itself. Furthermore, the processing unit 201 will output the initial data 40 to the user via the output unit 202 after completing the verification procedure and determining that the authentication is successful.
In various embodiments, the authentication information 41 may also be an audio associated with the verification information 511, such as the verification information 511 is a picture, a word or a number, and the authentication information 41 is the audio related to the picture content or the audio of the pronunciation of the letter or number, when the multi-dimensional barcode 5 is captured by the multi-dimensional barcode verification apparatus 20 to obtain the verification information 511, and decodes the barcode 501 in the barcode area 50 to acquire the authentication information 41 (audio) and play it, in step S83 of fig. 8, the processing unit 201 performs voice recognition (e.g., feature point recognition) to determine whether the authentication information 41 (audio) matches or corresponds to the image of the verification information 511, for example, the audio and the image are converted into characters or numbers respectively and then compared, so as to determine whether the authentication information 41 is related to the verification information 511.
Alternatively, the multi-dimensional barcode verification apparatus 20 may also determine whether the authentication information 41 (audio) is related to the verification information 511, for example, by directly converting the authentication information 41 (audio) into corresponding characters or numbers through the processing unit 201, and comparing the characters or numbers with the verification information 511.
Alternatively, as shown in fig. 7, the multi-dimensional barcode verification apparatus 20 may further include an input interface 204, the input interface 204 (e.g., a microphone) is used for receiving an audio related to the verification information 511, for example, a user speaks a voice related to the verification information 511, and the processing unit 201 is used for generating the first determination result or the second determination result by determining whether the input audio is related to the authentication information 41 (audio) to verify the authenticity of the multi-dimensional barcode 5.
In addition, the user can also determine whether the multi-dimensional barcode 5 is tampered according to the content played by the multi-dimensional barcode verification apparatus 20, for example, the user can compare the audio (the authentication information 41) played by the multi-dimensional barcode verification apparatus 20 with the verification information 511 to determine whether the authentication information 41 (the audio) is related to the verification information 511, so that the user can easily identify the authenticity of the multi-dimensional barcode without the need of server verification.
