Description

Product Validation

Technical field

The present invention relates to checking product, particularly can manufacture in more than one place and be in the product outside controlling immediately about its right possessory and use additional manufacture method or 3D to print the product manufactured.

Background technology

Many products (the product such as wrist-watch of general high value, or the product of the high sales volume of medium value such as clothes, whiskey and vodka, golf clubs, vehicle replacement part, medical product such as artificial femoral articulation and banknote) are forged.Anti-fake measure of making comprises safety label usually, and this safety label can comprise the mark that is difficult to copy such as hologram or have the merging of DNA of unique sequence code.

When a factory or when making product under co-controlling to the factory that reduces a lot, this relatively easily accomplishes.

But, along with the technical progress (it means and can make value product) in 3D printing and the more prevalent use of 3D printing machine, trend is the right that license creates according to designing the special product of or a small amount of made, and this design is incorporated in the media file being suitable for control 3D printing machine.

How to guarantee that the problem that product is not produced outside license terms has just occurred about licensor.This can pass through by licensee, occur by third party's media file or by carrying out the exceeding the quata to produce of reverse-engineering from the product made under the license.

Have been proposed in both 2D and 3D printings and control or monitoring production.

US2013/235412 discloses the two parts being divided into by media file and using continuously, and wherein before Part II can be run, Part I must be deleted.This means that license is except for being authorized to except the production of single product.Only printing relevant US7872772 in any case with 2D prevents the user in printing machine network from accessing printed text, unless ratified clearly.

Up to the present, the method for the production of the copy of product impact printed by the 3D of reverse-engineering is not proposed.

Summary of the invention

The invention provides the method for verifying possessory 3D print product, the method provides in fact better controlling the unratified production of such product.

The present invention includes the method for verifying possessory 3D print product, the method comprises assigns ID to each printed project and merges described ID as the parts in printing operation.

These ID will only be integrated in approved product.The product not comprising ID or the vicious ID of tool will be taken as not approved and forge, and may infringe one's patent, appearance design or copyright.

This ID can adopt many forms.Such as, it is merged safety label in the product during can being included in printing operation, and any commercial available such label can be comprised, such as a string or many strings alphanumeric character or ascii character, character, rune, picto-diagram or any other machine recognizable or discernible character of the mankind with Greek alphabet, cyrillic alphabet and/or Arabic alphabet, comprise bar code, QRC, hologram and comprise the geometric configuration of 3D shape, it be visible for it will to be positioned such that for inspection.External material such as DNA can be incorporated on surface that wherein they can be accessed or in described near surface or they can be accessed wherein testing location.

Or this ID can comprise machine-readable ID such as RFID label tag, its can: be passive, so as can by reader by induction to its power supply inquire it; Or active, there is its power supply.Such label manually can be introduced during printing process.Machine-readable ID like this can be hidden in the product and cannot see, and can be arranged only in response to inquiring operation especially, thus hinders reverse-engineering or directly scan and copy.Label can be supplied to licensee with suitable numeral, and they oneself will be difficult to copy.But, owing to what not having and does not have safety label not copy especially, so can printing process be suspended by printed text at the difference place of the process for introducing label and there is further safety, so that only copying label is the production enough not ensureing undetectable copy product, also the correct placement of copy label will be depended on.

This ID can comprise the information about licensor, licensee, name of product or part number, one or more date (such as relevant with design right or copyright protection date), the patent No. or institute's registered design registration number.The license of producing the product of limited quantity can cover the assignment of the unique code of each product.

Under ID is machine-readable situation, it can also be changeable, as by the new data of write in the register of RFID chip, described new data can comprise date that this ID is read and about it be at that time where with the information of the identity of reader.The information read can be sent to licensor's database.In this manner, ID can provide transaction history.

ID can be produced by printing process.The material of contrast can be printed as alphameric code, bar code, QRC code or any other is visible or machine-readable, and on the layer that can be printed on single printing or distribute to build 3D code between multilayer, this 3D code can be only just meaningful when watching from special direction.The material of contrast can comprise different colours material or differently in response to the different wave length outside the spectrum of such as infrared, ultraviolet or microwave and so on electromagnetic radiation and because of instead of obvious (unless being appropriately irradiated) material.

For such ID, print order can be established in printed text, and does not even need known to licensee.For multi-product license, file can contain counter function, and it changes ID code along with each printing so that all products have different ID and cause this file to work when all products through allowing are produced.But, the regulation that file will be updated can be made after paying license renewal fee.

Merge in ID to product according to the present invention the tracking that facilitates through the product of supply chain and allow the authenticity examination to demonstration of reselling.ID(such as hologram or other security printings for some types), often need expertise to examine authenticity, and for the ID of other types, need special equipment, because such as RFID chip or ID appear under ultraviolet, infrared or microwave.

But, the code of such as bar code and QRC code and so on can be read and be verified or smart mobile phone or panel computer otherwise by compatibly applying loading is read and is verified, its buyer facilitating expection examining at the scene, such as, the buyer of described expection can read this code and submit to it for examining (all under the control in application) to licensor and again can adding that buyer's information is as unique code, thus adds original producton location at each step place through supply chain.

The present invention also comprises for the method by verifying product to product applying ID label, described ID label is by smart mobile phone or similar bile devices (being after this called for short ' smart mobile phone ') is readable maybe can read described smart mobile phone or similar bile devices, described smart mobile phone or similar bile devices are programmed with to registration table report reading event, preserve the event chain of that product at this registration table place.

Can to be programmed smart mobile phone by load application, this application can control smart mobile phone to read ID label, to registration table report reading event and receive and show confirmation or other situations of authenticity.

Can by introducing the label of preprinted or realize verifying with smart mobile phone the ID label of compatible 3D print product by print character in the contrast material in printed substrate between the layer of 3D printing during printing, the instruction folding of described printing is in printed text.Character can be staggered between the layers or be printed as vertical or tilt to stride across multilayer, so that they perhaps can be only readable by the smart mobile phone applying loading suitably.Two or more ID label can be used in checking operation, described ID label can comprise from same font (counting the geometric configuration, bar code and other objects that belong to font in) or the character from different fonts, thus makes more to be difficult to copy and do not having more to be difficult under correct smart mobile phone applicable cases read.

Can stop when the ID of mistake is read verify operation, show product be not verified and may be forge.

Embodiment

A kind of method for verifying possessory 3D print product 11 of accompanying drawing diagram, the method comprises assigns ID 12 to each printed project and to merge described ID 12 be parts in printing operation.

The object of checking especially verifies the product made under the license on third party 3D printing machine.The printed text that operation printing machine makes product can send in any convenient manner, as such as sent on recording medium such as CD or on USB rod, or passes through the Internet download.Commonly, safety label can be sent by mail, but be likely the label that can be printed by licensee, the bar code that such as may print on paper or plastic sheeting or other substrates as can be integrated in 3D printing operation or QRC code.

Fig. 1 diagram is with the ID 12 of the form of safety label 12a, this safety label 12a uses to be used to the complicated printed label of that meticulous printing of banknote or hologram (such as also appearing on banknote and credit card and debit card) or RFID label tag, this RFID label tag can be read by reader, and this reader powers to RFID chip to launch the signal merging ID.

Fig. 1 illustrates the product 11 during printing operation following time: when product is successively laid by print head 14, label 12a is inserted in product by physics, and when completing printing with box lunch, label 12a will be embedded in interiors of products.

But, ID can be produced equally well by 3D printing process, and Fig. 1 passes through during being shown in 3D printing operation to print the alphanumeric ID 12b made by material being different from background material and the bar code 12c made in contrast material again.QRC code can substitute bar code 12c certainly.How dark the character depending on just printed material is embedded in it, and label will be more or less visible.Obviously, for visible inspection, material require is transparent and label is not very dark.And RFID chip can be hidden completely, because it is asked by causing its broadcast radio frequency signal.

Fig. 2 illustrates the distribution of the ID between different layers 11a, 11b, 11c etc. of product, and contrast material 13 is just printed as additional safety practice by using point or line 13.This can be merged into the 3D printed text of object together with label 12b, 12c in FIG.

When 3D printing is under the possessory control directly in right, any other ID except the ID be embedded into can be used, such as such as there is the external label of intelligent water or even stick-on hologram label.

Verification method disclosed here can form the basis of the 3D print product service for checking credentials, and the 3D that wherein owner of supvr and intellecture property signs a contract to be designed for the label obtaining their products prints.

Obviously, machine-readable tag has advantage especially following time compared with additive method: as RFID chip, when by reading new information and examining product to the register on chip, and especially when when reading RFID chip, back information is to supvr, this label can be changed, this make it possible to carry out supply chain follow the tracks of and original producton location tracking with valuable 3D print product of reselling.RFID chip has their unique identities burned by fabricator.The ID code that the information that user adds such as user assigns, possibly about the information of rule of origin, product design details such as color, weight and right owner, also can be burned, and this information can the database within hardware or in cloud be replicated.Additional information (comprising buyer's information) can be added in the stand-by register in RFID chip.

For smart mobile phone desirable can read ID(by being no matter directly through its camera or other sensors or the RFID reader by wired or wireless connection) and be written to chip by supply chain step details, thus to be returned to center or cloud database.But, according to an aspect of the present invention, it is possible that even when be written to label be impossible time there is same checking.

Fig. 3 illustrates the product 31 of the 3D printing merging multiple ID label, and described ID label comprises bar code 32, QRC 33, alphanumeric sequence 34, RFID chip 35,3D geometry form 36 and the small pieces 37 of intelligent water or DNA or other external chemical impregnations.

At least bar code in the middle of these and QR code 32,33 can be read by the application that can be used for smart mobile phone, sequence 34 can be read by character recognition application, RFID chip (its may depend on chip but writeable) can be read by special application, and application obviously can be designed to detect geometry forms 36.Smart mobile phone still can not detect DNA or other external chemicals, but this special ID can be when product is sent out for ' last-resort ' ID during detailed analysis, if every other all failed.

For current object, it is at least transparent or transparent in fact that product 31 is assumed to be in suitable district, so that the ID embedded can be watched and is imaged by the camera of smart mobile phone in spectrum.But, when be hidden cannot see time at least RFID chip can be read, and additional function can be incorporated in and make it future in available smart mobile phone or accessory, this smart mobile phone or accessory can access other ID label in other modes except optical mode.Such as, internal voids can be detected resonance or shape by ultrasonic scanning.

These ID labels can be incorporated in when production in the product of 3D printing.Bar code 32, QRC 33, sequence 34 can be rendered as the printing on paper or plastics, and it can be inserted in the product of half printing and pushes up upper so that other layers of printing are applied to and seal them.RFID chip 35 also can be done like this.But ID 32,33 and 34 can also be engraved under the control of print routine.

Be licensed for the print routine used on multiple copy can be suitable for tagging uniquely to individual copy and comprise how many copies in coding after the mode being appointed as 1/5,2/5 etc. with the printing of limited version on each copy and be licensed for production.

When engraving on ID label together with the printing of product, it can be printed on the layer that previously laid as in two-dimensional printed, or it can be printed on multilayer thus with this layering plane that laterally (no matter with it at a right angle or tilt) extends on there is character.Different ID labels by different orientation, thus can not have anything to increase or does not have in fact anything to increase the cost of printing, but increases in fact the cost of forgery.

Fig. 4 illustrates checking operation.

In step 21 place, suitably apply smart mobile phone scanning the one ID label of loading, thus form its camera images.This image of software process and it is compared with the data remained in application.If image is not by comparing, application continues to move on to step 22, is denied and reports to be sent to registration table as SMS or Email in step 22 place authenticity.If image is by comparing, in step 23 place, smart mobile phone scans the second label.If image does not pass through again, program moves on to step 22.If it have passed really, program moves on to step 24, show the message of Product Validation in step 24 place smart mobile phone and move on to step 26, in step 26 place, this message is communicated to registration table, and this registration table upgrades this destination register in step 26 place by the details of this special checking event.

Smart mobile phone can by carrying be used for the copy of the registry entries of product be discussed and itself serve as the certificate of checking.When only during verifying operation, smart mobile phone is consistent with registration table for registering entry, product just will be verified.When the reselling of product, ' certificate ' new custodian should can be handed over to by application content being transferred to another smart mobile phone under the supervision of registration table.
