Description

1353765 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method for verifying the authenticity of a physical object.疋[First technique] In real life, in order to ^^ I. I have to prove to others that I have issued a copy of my own signature or autograph on the document. . For example, a traditional transaction, such as a legally binding commercial transaction, usually has a written document (9) and a contract, and will be signed or stamped on it so as to confirm the rights and obligations of the parties to the transaction. And the purpose of confirmation in order to prove to others who the document was issued. ° Depends on the ground, in the context of e-commerce, business transactions must rely on electronic documents and digital signatures to establish their rights and obligations. The so-called "electric page S", the information related to trading behavior, its information type can be electronic form of text, sound, picture, shadow, and signature; and "digital 2d attached to electronic files for Identify and confirm the electronic document sign = (Signe〇's identity and the authenticity of the electronic file m can be seen: the function of the digital signature is similar to the function of the seal or autograph, except that the file it is targeting is an electronic file, not a physical file. At present, the 'digital signature is based on the cryptographically publicized password 2 (p_cKeyCryptosystem), also known as the "asymmetric cryptosystem Cryptosystem"), that is, in the department, the first, the mother - Users must make their own gold record pairs (1353765

Key Pair): - Put the private Jinxiang (10) t ^ force and a public gold (PUMlC Ke). The user must secretly save his private key and post his public key on the network. The user can then sign the document using his or her private account, and the recipient of the digital signature can use the signer's public record to verify the validity of the digital signature.

In addition to the safe and effective digital signature, in addition to the signatory must sign the electronic document in a correct and effective way, the validity of the digital signature generated by the signer also requires a suitable verification method to verify the digits. The signature mechanism (Digital Sig_e is based on CrmQgraphy) to define the (4) signature generation and signature verification method. This mechanism includes the chapter generation mechanism (

Gen__ Mechanism) and the signature verification mechanism (^e Venfication Mechanism). The "signature generation mechanism" refers to the method or procedure by which the signatory generates a digital signature, and this mechanism can be regarded as a mathematical algorithm. If the signatory is to sign, he can use the electronic file to be signed and the entry he owns as the input value of the calculation. After the calculation of the algorithm, the digital signature of the electronic document can be obtained. On the other hand, the “signature verification mechanism” refers to the method or procedure used by the verifier to verify the validity of the digital signature. If the verifier receives the signatory's electronic file and digital signature, he must use the electronic file, the digital signature, and the signer's public key, and use this mechanism to verify the validity of the digital signature. The cryptographic technique closely related to the digital signature is the One-Way Hash Functi〇n, a one-way hash function that is a mathematical method that can compress input values of arbitrary length into fixed-length output values. The function or the 1353.765 is different, and its input value cannot be derived from its output value as the current common = 5 or equal one-way hash function. In the security (that is, to prevent non-forgery - a legitimate digital signature, and to prevent the attacker from signing the second message = the fourth (four) record) and efficiency considerations, the security of the digital sign ^ ^ bow into the early hash The function is in this mechanism. In other words, in the early sign-off mechanism, the signer must first convert the electronic text into a fixed-length bit through a one-way hash function, which is called a data summary (Data gest β| The data is summarized to generate a digital signature; similarly, the verifier must first use the one-way hash function to convert the electronic file into a fixed length data summary and then perform the verification action. Therefore, the digital signature is described. The related description can be summarized by the conventional digital signature structure j shown in FIG. 2. When Alice (4) (4) wants to sign a digital file η, the hash function 12 is used to convert the digital file into a -- Message Digest I 13 'Reuse the private key it owns" encrypts the message digest 13 into a digital signature 15 and transmits the digital file 11 along with the digital signature 15 to Bob (B〇b) After receiving the digital file η and the digital signature 15 , the digital file 1 is converted by the hash function 12, and the first _ message digest 13 is also obtained. Bo to the certification body (not shown) obtained _ with Alice After the public gold=14 corresponding to the public record 16, then the digital signature is 15: decryption, and a second message summary 17, and finally, the first message and the second message Abstract 17 is to check whether the kisses are right or not. The digital file u received by the table is indeed sent by Alice. 1353, 765: In the past year, due to the development of the Internet, it was necessary to use the postman or The courier assists in the delivery of the information, and must receive the information, in the current E era, the second door - τ must be hit by a button, then pass through the '", the Internet of the Games,,, evaluation It is known that the recipients arrive at the same time: and because of the substantial increase in the convenience of message transmission, the bombing incidents using the Internet have also been generated. For example, the report of the Times Daily Times pointed out that many victims have received The boxing month email informed that “the family has informed the family that they have been subject to the mandatory freezing control of the government’s gold officials’ meeting because they have been used by the illegal group. And the monthly reply is as soon as possible, and the prosecutor (actually counterfeit) will be contacted. Make one, . , IB At Step by step. Although, using the current digital = machine (four) (four) materials to carry out the step by step, in its verification method for - protection t: in & non-cooked wheel computer related fields (especially learning = discipline The elderly), how to obtain the open record of the test? The link to the website for verification? The procedure is complicated. Therefore, how to simplify the verification process of the digital signature has become an effort of the relevant industry. The direction of the invention is therefore related to the invention. Therefore, the purpose of the invention is to provide a method for verifying the authenticity of a physical object by using a digital signature code. The chapter code verification entity method includes the following steps: (4) Digitalization - the surface content of the physical object, and produce a digital data (b) After the digital signature process using the private data and gold record for the digital data 1353765

And produce a digital signature. (C) Convert the digital signature into a digital signature code. (d) - a code storing the digital data, the digital signature, the digital signature code, and a signature number relative to the private key to process the input of the digital signature code by the server. (e) The code processing server host uses the signature number to obtain a public key from a signature certificate management server.

(0) Use the public key in conjunction with the digital signature verification procedure to verify whether the digital signature is true. The effect of the present invention is to simplify by replacing the use of the digital signature with the digital signature code. The verification procedure of the current digital signature, and further derived a wider range of convenient application methods. [Embodiment] The foregoing and other technical contents, features and effects of the present invention are combined with one of the reference patterns in X. The detailed description of the preferred embodiments will be apparent.

Before the present invention is described in detail, it is to be noted that in the following description, the 'fourth element' is denoted by the same reference numeral. Referring to FIG. 2, FIG. 3 and FIG. 4, a first preferred embodiment of the method 2 for verifying authenticity of a physical object using a digital signature code includes the following steps: first, as shown in FIG. 21, by means of a conversion device 32 Hi The surface content of the physical object 31 and produces a digital data 331 in the computer, -, the end machine 33. In the preferred embodiment, the physical object ^ is an entity 9 < S ) 1353765

Cattle 11 and. The conversion device 32 can be regarded as a common scanning device 'and scans the physical file 311 through the scanning device to input the content of the physical file 31 to the computer terminal device. However, except for the scanning device pair In addition to scanning the physical file 311, all (or part of) the content text of the physical file 311 may be entered in a two-way manner and an electronic file file may be generated and stored in the computer terminal 33; The surface content of the physical object 31, its plain text (the format of the coffee (four) block is in accordance with the format of the execution-digital seal 35, such as the file with the name of the auxiliary building (8), the Tan case with the secondary sandalwood 4, and the secondary sandalwood Name (called, sub-mail, mobile phone newsletter (SMS), web page file (html board called or 疋 extensible markup language format text agency). In addition, in real life, the physical object 31 can also be Other non-physical documents 3 ιι Shape 2 such as three_three-dimensional object 312 'and pass through - having a camera or photography function conversion device 32, such as a digital camera device or a digital camera device, etc. After the appearance of the 312 is taken, it is input into the computer terminal 33 in a digital data format 33 (still image or state image), and in addition, a network communication mobile phone (not shown) or an individual having a function similar to the computer 4 machine 33 The mobile electronic device f (not shown) can be used, and therefore should not be limited to the one disclosed in the preferred embodiment. ^ In addition, in this step 21, the conversion device 32 can also be digitized. When the surface content of the two physical objects 31 is simultaneously added to the surface of the non-physical object, the digital data 331 is generated in the computer terminal, and the surface content of the non-physical object can be executed by the digital signature holder. 10 < S ) Filled with the description of 'the aforementioned physical document 311, which can be a national identity card, a health insurance card' driving license, vehicle loan information, vehicle information, electronic display, Graduation certificate, name>;, judgment, contract, power of attorney, agreement, letter of credit for medical diagnosis report, subpoena, arrest, sorrow, professional certificate, work permit, commodity price list, commodity guarantee, 夂receipt, Page text, original, copy, photocopy or copy, resume production history, various work permits (including foreign workers), company certificate, press card, :::, pass, material certificate, technical professional license, letter of appointment, service year - Ming, (4) Articles of the article, advertising signs, advertising dm, texts, A (personal or company) announcements or statements, slogans, textual illnesses and disability in the photo), Barthel Index, newspapers The words in the magazine period, (management fee) (4) bills, the words in the passport visa, the declaration text of the nature of the ==, the lottery ticket, the picture description of each of the Nakata paintings, the order, and the various types of reinstatement (such as Seven-use rent> books, various points...!:), e-mail Chinese characters and other body-related texts; such as texts that are representative of recognition or their credibility is extremely important and must be guarded against forgery = enter as shown in step 22 Use-private gold...the digital chapter=金余^ In the embodiment, the m-chip card (® not ^) used for the signing of the digit (4), that is, the current contact crystal=type crystal card, such as ISQ7816 Or not for example IS014443 + Together with a said sheet not shown), and the read through the computer terminal 33; and ^; I card / card device (< take items acquired, and then through

As shown in Fig. 23, the digital signature 35 is converted into a digital signature code 37. It is worth mentioning that in the preferred embodiment t, a one-way hash function 36 is utilized (then, F„>93 Or the operation of SHA-1, etc., converting the digital signature 35 into a -digit signature code 37; such a one-way hash function ^ not only has the property of converting arbitrary length bit data into fixed length bit data. Externally, there is a "one-way irreversible" trait that cannot be reversed from the result that has been converted by the one-way hash function 36. In addition, for the same one-way hash function 36, the difference is different. Input data will be different = The computational complexity of the output of the shell material 'plus the early hash function % is quite high, and the unilateral hash function % tampering with the output data is very _; however, in practical applications, the digital signature code 37 can also: manually deliberately or randomly directly designate the digital signature 35 - on behalf of the "should not only be bribed in the manner described in the preferred embodiment." In the _23 in the generation of the digit Material code 3, can be further transmitted through a code generating device (夂^^ Μ ^ ^ (not shown), and the generated digital signature code 37 is converted into a bar code. Then, as step 24 new; γ Receiving the digital host 38, the code processing server host 38 storing the digital data 33, the 12 1353765 digital signature 35, the digital signature code 37, and a signature number 332 relative to the private key 34 The code of the code 37 is implemented in the preferred embodiment, and the code processing vocabulary host 38 first checks whether the digital signature 35 is still within its valid period when receiving the input of the digital signature code 37, if overdue, Stop the subsequent verification of the digital signature 35 And the code handles the ship host% every every preset period, such as every day 'weekly or monthly, that is, it automatically checks whether the digital signature 35 is still within its valid period. In addition, in addition to the above-mentioned inspection position signature 35 is (four) The code processing ship host 38 may also have a meter (not shown) for counting the number of signatures (or the number of verifications) of the digital signature code 37, and receiving the digits, outside of its validity period. (4) When the input of the code 37 is used, the counting device is used to check whether it exceeds the preset number of times. If the preset number of times exceeds the preset number of times, the subsequent verification operation is stopped for the digital signature 35. And the digital signature code η is in the At step 23, if there is still a process of bar coded, then at step 24 the code processing servo host % receives the input of the digital signature code 37 by means of a code reading device. It should be noted that the private gold wheel 34 and the public gold record mentioned in the preferred embodiment are actually the current "asymmetric encryption system", and the "asymmetric encryption system" is more commonly used. There are three mechanisms in the field of digital signature: RSA digital signature mechanism: In 1978, the three states of the State and Adl_n (RSA78) used the difficulty of decomposing large prime numbers to propose the RSA digital signature mechanism. Currently, VISA, MasterCard, IBM, 13 <S) 1353765

The Secure Electronic Transactions (SET) developed by Microsoft, HP, etc. is based on the RSA digital signature mechanism. When the system is set up, each user can first select their private record: two large prime numbers (p, q) and an integer d<(pl)(ql), where d is mutually compatible with (pl)(ql) Then calculate its public key: N=p*q and e=dl mod (pl)(ql), where mod represents the modulo operation (that is, the remainder operation).

ElGamal Digital Signature Mechanism: T. ElGamal (E1G85) proposed the ElGamal digital signature mechanism in 1985, and the security of this mechanism is based on the difficulty of solving the discrete logarithm problem. Before using this mechanism, the system will first publish a large prime number P and the original root g of the modulo P. After that, each user first selects an integer X smaller than p-ι as the private key, and calculates his public key y=gx mod p. DSA Digital Signature Mechanism: This digital signature mechanism was proposed by the National Institute of Standards and Technology (NIST) in August 1991 (DSS91, DSS92) with the same security as the ElGamal digital signature mechanism. , are all based on the difficulty of solving the discrete logarithm problem. Before using this mechanism, the system first selects a prime number p of 5 12 bits and a prime number q of 160 bits, where p-Ι can be divisible by q. In addition, the system optionally selects an integer h less than p-1 and calculates g = hp - l / q mod p. Finally, the system parameters {p, q, g} are published. Therefore, once the user knows the system public parameters, he can choose an integer X smaller than q-Ι as the private key, and calculate his public record y=gx mod p. 14 1353.765 The "Asymmetric Encryption System" used in the digital signature mechanism is readily applicable and applicable to those skilled in the art and should not be limited to the specific examples of the preferred embodiment. Then, as shown in step 25, the code processing servo host 38 obtains a public key 4 corresponding to the signature number 332 from a signature certificate management server 39 using the signature number 332. In the preferred embodiment, the signature voucher management server 39 can be installed in the Ministry of the Interior Natural Person Certification Management Center 'Ministry of Commerce and Industry Voucher Management Center, government legal person certificate or other private certificate management center. Then, as shown in step 26, the public key 4 is used to match the conventional digital signature verification procedure as shown in Fig. i to verify whether the digital signature 35 is true. In short, because each private key 34 has only one corresponding public key 40, it can decrypt the digital signature 35 issued by the private key 34. Therefore, if it can be When the user's public key 40 unlocks the digital signature 35, it indicates that the digital signature 35 is indeed signed by the user's private key 34, thereby implementing the digital signature 35. The discriminative test; likewise, it is not a modification of the present invention because the use of the public key 进行 to verify the digital signature 35 is not an improvement of the present invention, and therefore no further need to be repeated here. ^ Finally, as shown in step 27, the interpretation of the content of the digital signature 35 that has been verified by the public key 4 is consistent with the surface of the physical object 31. After the digital signature 35 has been verified by the public 4 gold transmission 40, it can be checked by the naked eye for the digital data 331 • the manual check method to check whether the content has been tampered with. 15 < S :) In the case of Chen Ruiren’s prosecution on February 8th, the case of the swindler’s fraudulent scam, it is expected that the content of the essay will be fraudulently obtained for the signing and verification of the above related i i 3: The preferred embodiment············································································ Voucher wafer card: The role of the certificate chip card issued by the government legal person certificate issuing unit is 35% early. x,. About the generation of the digital signing early code 37 'First, as shown in Figure 6 The user clicks on the signature function option 42 in the signature and verification form of the screen displayed on the screen of the computer terminal 33. Then, click the file open button 43' to view the user and find the user. The name of the file to be executed for the digital signature, as shown in the Select File dialog box 44 of Figure 7, is the electronic file named "Court Voucher"; then, the selected "Court Voucher. Plus" is selected into the form. Execute interface 41, and as shown in Figure 8, in the form execution interface 41 file path and name display column 45 presents its own path and name, and then on the digital signature valid days selection form 46, select this number of times sign early code, 37 effective days, if the user is using When the chip card is used, the chip password must be entered in the chip card password input field 47 (see Fig. 9); finally, after the signature generation button 48 is clicked, the signature code generation block 49 as shown in Fig. 1 The signature code 37 with the minor number "39c3ee72! 1". However, 'Operation 1353765 on verifying the authenticity of the digital signature code to verify the authenticity of the entity' firstly, as shown in FIG. 11, another user opens the above signature on his computer terminal 33 (which may be the same or a different part) And verifying the system and clicking the verification function option 5 on it; then, as shown in FIG. 12, the "39c3ee7211" signature code generated in the description is generated by inputting the digital signature code 37 in the signature code input block 51 as shown in FIG. 37 and click the execution verification key 52; if the signature verification is successful, as shown in FIG. 13, a verification success dialog 53 is popped up, and then, as shown in FIG. 14, the verification result display box 54 is presented. A real signature person name 55, a set of signature valid period 56, a set of signature holder voucher valid period 57, and an archive content display block 58 for presenting the content of the digital poor 331 associated with the digital signature 35 Finally, through the user's visual identification, the digital data 331 is further checked for content to verify whether the content of the ticket of the Banqiao District Court of Figure 5 has been maliciously altered. It should be added here that if the signatory is signed by a real judge using the government legal person certificate chip card, the name of the aforementioned signatory 55 will be displayed as "Qiu Jiqiang, Banqiao District Court Judge" (not shown) It is not the word "Qiu Jiqiang" as shown in Figure 14; in addition, the content of the "court summons txtj file" displayed in the file content display block 58 is the subject of the voucher input by the judge. The electronic file file generated by the whole content or part of the important content, etc. In the above example, the signature code 37 of the number "39c3ee7211" appears in the signature code of Figure 1. Then, one or more of the superiors or other related legal persons that Judge Qiu Jiqiang belongs to, such as the grounds in Figure 5, can also perform the signature code 37 of this time, and perform Figures 5 to 17 <S) 1353765 22 Each step, to generate a complex signature code (not shown). The copy:: code (not shown) can be printed or written in Figure 5, which is not contained in the local court. As shown by the γ 1 of the line surname Μ, the other user does not verify the two signature codes in his computer to the end machine 33 (the figure does not show that the physical object is verified by the "number (4) chapter code of the present invention: The pseudo-method 2" can effectively prevent the social frauds described in the town from happening endlessly:

People's News Network 2_/() 8/11/ reported: "... disguised as a staff member of the Ministry of Justice, with a forged official document of the Ministry of Justice, defrauding the victim suspected of illegal money laundering, so must; tie the property, if the victim If you don't want your account to be smashed, you must first send hundreds of thousands of money to fake the seizure. A few rude documents, plus the public's lack of legal knowledge, let the group at least succeed in just six months. —+ 〆付干干万万,...”. If at this time, the victim receives the signature code 37 on the official document using the mobile phone input and transmits it to the generation.

Code processing (4) The main 8 and from the returned message, compare and interpret whether the official document of the Ministry of Justice is forged. In addition, a principal writes on the bank's paper voucher to fill the 10,000 and use the private seal. Then the client writes another remittance slip to remit the ten thousand remittance slip, the principal uses the invention. The paper voucher is handwritten with a signature code 37, and another digital signature code 37 is written on the money order, and the voucher data and the remittance slip are transmitted to the bank code number service host 38. Therefore, when a trustee enters the bank and holds the paper-based subpoena, the bank teller and the computer terminal 33 that can use the bank enter the above-mentioned digital signature code 37 to perform verification of the contents of the client. Pseudo 18 < S ) Large amount (cash entrustment) can be obtained in the final operation, and then how to use the digital signature code to verify the entity = true injury method 2, how to apply it to daily life, Improve the convenience and practicability of its digital signature 35 verification, and make a more diversified application description: (1) Simplification of the procedure for verifying information credibility:

Whether or not; as a result, it is necessary to strengthen the confirmation. When a passenger wants to sit in front of a tour bus, he can drive the driving information of the tour bus with the digital signage code 37. The business card or the vehicle is marked with a mark - printed with a digital signature. When the code 37 is used to respect the information file, the passenger can immediately pass through the handheld electronic device (not shown), such as a personal digital assistant (PDA), a notebook computer, a mobile phone, etc., through various communication methods such as the Internet. The code processing servo host 38 described in the preferred embodiment is connected to the line and inputs the digital signature code 37 to perform a verification operation when the code processing servo host 38 utilizes the digits described in the present invention. After the verification code 2 verifies the authenticity of the physical object, the verification of the physical object can be used to check whether the driving record of the tour bus is good or not. Whether it is good, etc., to prevent counterfeit driving-related information from deceiving passengers and avoiding potential problems arising from road safety. In addition, when a web page viewer reads the content posted on a web page with a digital signature code 37, the digital host can be input by the code processing server 38 described in the preferred embodiment. Chapter 37, in order to seek the verification of the far-credit signature certificate management server 39, in 19 1353765 to verify the authenticity of the received information, in order to assist the web page viewer in the true and false information explosion torrent Seeking reliable and truthful messages without being misled by false messages. Therefore, by the above method 2 of verifying the authenticity of the physical object by using the digital signature code, it is possible to avoid the occurrence of the identity document forgery incident as stated in the China Times on the 2nd and 8th of the year: "The skill of the fraud group Under the falsification, hundreds of military officers and military identity cards that had served in an army unit of Hsinchu, A Bingge, became suspects and impersonated the bank to apply for credit card 'car loans and mortgages, and = 10 million yuan of head information. Criminal The bureau said that the Nine Teams arrested five suspects, including Yu Zhengxian, and issued a large number of fake military identity cards, national identity card and computer equipment. Police investigation, suspected Yu Zhengxian (廿 eight years old) from October 94 From the beginning, the counterfeit military identity card, the remaining article, the national identity card 'health insurance card and other documents were packaged into a military officer's identity, and a fake document such as a military identity card and a salary certificate was attached to the bank's application card. The head 'from the upper soldier to the major' or the corporal is automatically promoted to less, and the knife-hunting 'hundred people's heads of household registration, are located in Jianshi Township, Hsinchu County, 2, and the troops are more concentrated in a certain brigade-level unit of the Army. Team; Zunfang observes again, the application capital of the attachments of the gangsters, the forgery, the eve, the ancestors, the new capital and the identity card are not checked. It's hard to detect." Drop (-) Auxiliary Verification for Time-sensitive Messages: When an email recipient receives a 37 missing search | inch with a digital signature code, through this better fee + its digital signature code 37 in the good example of the code described in step 24 of the word processing

< S 20 1353765 The machine 38' performs relevant verification on the expiration date of the digital signature 35 to determine whether the message has been written off because the missing child has been found, and the expiration date of the e-mail has been cancelled. The search for letters was continually forwarded by the workers, but after the missing children were found, it also led many people who were still unaware of the situation to continue to help to search and spend a lot of social resources. (3) Verification Whether the product is genuine or not:

T- Consumers want to buy - cosmeceuticals, because the cosmeceutical supplies are directly in contact with the body surface of the consumer, or even oral into the body, add to the conscience, many unscrupulous people in the society in order to seek more In the interest of creating a large number of black-hearted fake drugs that will hurt the human body and make it flooded the market

'But' that the money passed the identification of the relevant qualified label or drug inspection number of the existing Health Bureau, still lost to the falsified deception of the Xiaoye people; therefore, in view of this increasingly serious social problem, the number of signatures can be Printed in the package of the cosmeceutical product or on the inner cover' and through the method 2 of the invention for verifying the authenticity of the physical object by using the digital signature code, providing verification of the credibility information of the ingredient indication and source of the cosmeceutical product, In order to eliminate the harm caused by the fake medicine to the human body; another 'in conjunction with the installation in the code processing word service host 38 mentioned in the step 24' is used to count the digital signature code 37 input times (or the number of verifications) The counting device assists, and allows the digital code 37 to provide only "one-off" verification, and thus prevent the legal digital signing code 37 from being repeatedly forged and prevented. Transfer to ny ^ 1 ,, and once the digital signature code 3 7 is used, the user's network ip address (or mobile phone number) will be automatically stored in the above code server host 38 Le 埽 5 5 recorded, connected The code servo 21 1353765 main unit 38 advances the stored record to the computer terminal 33 (or mobile phone) to which the person who made the digital signature code 37 belongs. Similarly, the digital signature code 37 with ""*次性" can also be used in the bottle cap or bag of alcohol or other beverages, so the number can only be known when the wine or drink is opened. Signature code 37, and further verify that the wine or drink is a reliable quality and prevent China Times from 2008! The unfortunate incident reported on the 31st of the month: "It is currently in the peak season of the Spring Festival gift season, but the fake wine market is flooding the whole province. The Tainan District Inspection Department has commanded the police to transfer the soldiers to the 19th road. Nearly 4,000 bottles of fake wine, followed by Jinmen sorghum, followed by foreign wine, and more than 2,000 liters of semi-finished products and hundreds of thousands of labels; these fake wines are so confusing that even the original wine merchants are not easily identifiable. What surprised the police was that the company even faked the anti-counterfeiting stamps. A director of the Golden Gate Winery accompanied him. He took out the professional benefits to distinguish the authenticity of the stamps. The naked eye could not recognize them. On the other hand, the anti-counterfeit seal of the current wine has been completely cracked, and the post-war police will be in a difficult battle for the investigation of counterfeit fake wine." Given the China Times in 2008! The fraud reported on the 29th of the month: Wulai Meirentang Hot Spring Resort in Beixian County, commissioned by Shangen Management Company to assist in the operation the previous year. I did not expect that after the expiration of the period, many consumers found accommodation and bathing at major auction websites. Coupons, etc., are the same as the coupons sold in the clubhouse, but the ticket number is forged. The investigation was carried out by the cadres of the Shangen Management Company, who were suspected of falsifying the total price of more than 20 million yuan. The incident of the incident was that the beauty soup hot spring club industry has been found by consumers since September last year. Accommodation, bathing, meal coupons, etc., ticket number is not originally set in the clubhouse 22 < £) 1353765 of the serial number 'paper and printing but the mold is flawed, suspected that the printing process appears ^ use the signature code of the invention 37 to verify The effective nature of the sub-verification can be used in conjunction with any "valuable or non-valuable "entity admission ticket (voucher)".
