适用于确认一个安全标志的方法和系统 Methods and systems used to confirm a safety signs

交叉参考的相关申请本申请涉及美国临时专利申请号60/290,117题为“异类的视觉可变的水性墨水的成分”和申请号60/289,989题为“适用于喷墨打印机的同类感光性视觉可变墨水的成分”,并已委托予本发明的受让人,已于2001年5月10申请。 CROSS-REFERENCE TO RELATED APPLICATIONS This application is related to U.S. Provisional Patent Application No. 60 / 290,117, entitled "optically variable component heterogeneous aqueous ink" and Application No. 60 / 289,989, entitled "applies to an ink jet printer like photosensitive visually change ink ingredients "and has entrusted to the assignee of the present invention, an application in May 2001 was 10

发明领域本发明主要涉及一种物件的鉴定,例如,钞票、证书和邮资、特别涉及通过确认上述物件所提供的安全标志来鉴定该物件。 Field of the Invention The present invention generally relates to identifying an object, for example, banknotes, certificates and postage, particularly to confirm that the above object provided by the security mark to identify the object.

技术背景众所周知,通常是采用对在可视光谱内具有高反射对比度的图像敏感的自动检测仪,用于机器处理各种类型携带信息的票据,标签,商标,邮资及类似安全标志。 Technical background is well known, usually by an image with high contrast reflection in the visible spectrum-sensitive automatic detector for processing all types of portable machine notes, Labels, Postage and safety signs similar information. 另外,众所周知,也可以采用对能产生较短波长的激发(例如,紫外(UV)激发)的安全标志的荧光发射敏感的自动检测仪。 Further, it is known, may be used to produce shorter wavelengths of excitation (e.g., ultraviolet (UV) excitation) of the security label of the fluorescent emission sensitive automatic detector. 例如,在邮资计量的领域中,邮件携带采用荧光墨水印刷的邮资邮戳可增加邮件的机器处理。 For example, in the field of postage metering, the message carrying the fluorescent ink printed postage indicium increase the mail processing machine. 在美国和加拿大,自动设备可通过检测黏附在邮件上的邮资邮戳的红色荧光来适当地面对着或确定各个邮件的方向。 In the United States and Canada, automated equipment can adhesion mail postage indicia on the face of the red fluorescent or appropriately determined by detecting the direction of individual messages. 邮资服务面对设备采用简单的检测仪来定位荧光。 Postage service face a simple device to locate the fluorescence detector. 该检测仪不能确定荧光和邮戳的图像是物理相一致的,于是就限制了检测仪确定安全标志的鉴定能力。 The detector can not determine fluorescence and postmark image is consistent with the physical, so they limit the detector to determine the ability to identify safety signs. 正如本文所使用的,术语“红色荧光”并不是指墨水的可见颜色,而使之在光谱的红色区域中的荧光。 As used herein, the term "red fluorescence" does not refer to the visible color of the ink, leaving the fluorescence in the red region of the spectrum.

正如本文所使用的,“荧光安全标志”是指在光谱的定义区域中可暴露于较短波长激发光(例如,UV光)的荧光的安全标志。 As used herein, "fluorescent security mark" means a defined area of the spectrum can be exposed to a shorter wavelength excitation light (e.g., UV light) of the fluorescent security mark. 在入射激发光和荧光发射之间波长中的变化可以清晰地区分荧光和直接反射。 Between the incident excitation light and the fluorescence emission wavelength of the fluorescence changes can be clearly distinguished and direct reflection. 荧光安全标志可有效地应用于伪造票据,有价证券,身份证,证券纸等等的检测。 Fluorescent safety signs can be effectively applied to counterfeit bills, securities, identity cards, bond paper, etc. testing. 复制安全标志的荧光的困难阻止了复制并且提供了赝品的法律证据。 Hard copy fluorescent safety signs to prevent duplication and legal evidence provided fake. 在这些应用中,安全标志是条款的检测,产生的标志,以及自动条款的识别。 In these applications, the security mark is detected terms, and the automatic item identification sign produced. 对这些应用来说,荧光的亮度是重要的。 For these applications, the brightness of the fluorescence is important.

伪造者没有采用具有机读荧光墨水的打印机,而是通过在荧光的背景上复制标记或者在复制的标记上涂覆荧光材料的方法,就能够产生可发出荧光并可机读的安全标志。 Forger does not use having machine-readable fluorescent ink printer, but by copying the marking on the fluorescent background or in the method of coating a fluorescent material marked on the copy, it is possible to produce a machine-readable fluoresce and safety signs. 在这两种情况下,原始的和复制的标记是可识别的。 In both cases, the original and the copy of the tag is recognizable. 一个法律验证系统可以产生这样的识别,正如本文所讨论的。 A legal authentication system can generate such recognition, as discussed herein.

手动的法律检测系统可以简单的是一个可视光源和一个紫外光源,还具有一个可在这两种光源之间切换的开关。 Manually law detection system may simply be a visual light source and a ultraviolet light source, also has a switch between the two source switches. 操作者可以观察在这两种光源下的标记,并且在紫外光的照明下验证图像的荧光和背景的没有荧光。 The operator can observe the mark in both the light source and under UV illumination verify that no fluorescence image and background fluorescence.

当采用可视光源来照明一个原始的安全标志时,与纸张的发亮背景相比照,图像是发暗的。 When visible light to illuminate an original safety signs, compared with the paper's shiny background photos, the image is dark. 当采用紫外光源来照明原始的安全标志的图像时,则与纸张的低荧光背景相比照,图像是发亮的。 When using an ultraviolet light source to illuminate the image of the original safety signs, the paper compared to low fluorescence background photo, image is shiny. 同样,采用可视光来照明一个复制的安全标志相对于发亮的背景显得较暗。 Similarly, the use of visible light to illuminate a copy of the safety mark relative to the background of shiny dark. 与在紫外光照明下的原始安全标志的图像性能相比较,印刷在荧光背景上的复制安全标志或采用荧光材料覆盖印刷的并采用紫外光照明与发亮的荧光背景相比照就显出暗的图像。 In the performance of the original image with the security label under UV illumination compared to printing on a fluorescent background copy security label or fluorescent material covering the printing and illuminated by UV light and compared according to the background fluorescence show dark images.

旋转的和其它凸版印刷机的邮资计量采用浸渍泡沫海绵或其它多孔媒介中的墨水的滚筒在信封上留下邮戳。 Postage metering and other letterpress rotary printing press by impregnation foam sponge or other porous media in the drum ink left postmark on the envelope. 适用于凸版印刷机计量的红色荧光复制的墨水包括工色、蓝色、绿色和黑色的墨水。 Red fluorescence copied apply letterpress printing ink metering, including workers, blue, green and black ink. 例如,美国专利号2,681,317;2,763,785;3,230,221;3560,238;3,928,226和4,015,131披露了适用于该目的的红色墨水。 For example, US Patent No. 2,681,317; discloses suitable for the purpose of red ink 3,928,226 and 4,015,131; 2,763,785; 3,230,221; 3560,238. 一般来说,这些墨水含有低蒸发压力的非水性的基于溶剂的媒介物体系,并具有高的固体浓度、高的粘性、高的沸腾温度和低的表面张力。 In general, these inks contain a low vapor pressure of the non-aqueous solvent-based vehicle systems, and has a high solids concentration, high viscosity, high boiling temperatures and low surface tension. 凸版印刷技术缺乏印刷可变信息的数字印刷的能力。 Toppan Printing variable digital printing technologies lack the ability to print information. 因此,这些凸版印刷机的墨水就不能用于喷墨打印机,因为这些墨水需要稳定的溶解度或随小颗粒的稳定流动性,低的粘性和特殊的表面张力。 Therefore, these can not be letterpress printing ink for an inkjet printer, since these inks require a stable solubility or with a steady flow of small particles, low viscosity and specific surface tension. 在目前的压电式喷墨打印机中,液体墨水的粘性可以从大约1.5到15厘泊(cps),而在热敏喷墨打印机中则为从1至5cps。 In the current piezoelectric ink jet printer, viscous liquid ink may range from about 1.5 to 15 centipoise (cps), while in the thermal inkjet printer was from 1 to 5cps. 喷墨打印机墨水的表面张力希望是在30至50dynes/cm之间。 Surface tension of the ink-jet printer hope is between 30 to 50dynes / cm. 在美国专利号5,681,381中披露了一种红色水性红色荧光墨水的例子,所披露的墨水符合适用于邮资的USPS的需要,同时还兼容于在喷墨打印机中的使用。 Discloses an example of a red aqueous ink of red fluorescence in U.S. Patent No. 5,681,381, the ink disclosed in compliance with the applicable USPS postage required, is also compatible for use in an ink jet printer. 这些墨水在有效期间是稳定的。 These inks are stable in the effective period. 这些墨水的主要成分是基于说,辅助溶剂以及水溶性荧光调色剂的渗透性溶液。 The main components of these inks are based on said auxiliary solvent solution permeability and water-soluble fluorescent toner. 这些墨水可设计成通过限制光学的限制来获得所需的荧光强度,使之光学强度低于机器阅读所需的正常强度。 These inks may be designed to limit by limiting optical intensity of the fluorescence to obtain the desired, so that the optical intensity lower than the intensity required for normal reading machine.

已经开发了邮资邮戳和邮资机器,这些设备采用了数字打印特别是喷墨打印。 Has developed a postage postmark and postage machines, these devices especially using digital printing ink jet printing. 一个实例是由美国Pitney Bowes公司(Stamford,Connecticut,USA)所制造的个人PostTM邮资计量设备。 One example is the US Pitney Bowes Company (Stamford, Connecticut, USA) manufactured personal PostTM postage metering equipment. 众所周知,在业内,常常是使用数字打印机来打印具有有效日期的红色及红色荧光的邮戳。 It is well known in the industry, often using a digital printer to print in red and red fluorescence with a valid postmark date. 数字打印邮戳提供了明显超越凸版印刷邮戳的优点。 Digital Print postmark provides significant advantages beyond the letterpress printing postmark. 喷墨打印提供了一种打印具有高密度可变信息邮戳的手段。 Inkjet printing provides a high-density print variable information postmark means. Pitney Bowes'PostPerfect计量通过热传移打印的方式来产生具有有效日期的红色、红色荧光邮戳,而个人邮件办公装置可通过喷墨打印来产生红色及红色荧光邮戳。 Pitney Bowes'PostPerfect shift measurement by means of heat transfer printing to produce red, red fluorescence with a valid postmark date, office equipment and personal messages can be generated and red fluorescent red postmark by inkjet printing. USPS IBIP程序可允许使用黑色、可机读的邮戳。 USPS IBIP program may allow the use of black, machine-readable postmark. 邮局办公设备一般都是使用面对可识别标志或通过附加在邮戳上的荧光标签来调整携带着IBIP邮戳的邮件方向。 Office equipment is generally used in the post office could face identification or postmarked by attached fluorescent labels to adjust the direction of carrying the mail IBIP postmark. 邮资服务器可采用适用于增值服务、适用于邮戳的密码鉴别和适用于获得标志信息的各种可机读变化信息。 Postage server can be applied to value-added services, passwords and identification of suitable machine-readable indicia change information for a variety of signs to get information. 与凸版印刷技术相比较,数字印刷机可以在不减少印刷次数的条件下提供印刷的质量和对比度。 Compared with the letterpress printing technology, digital printers can provide print quality and contrast without reducing the number of printing conditions. 该图像可以采用直接非接触的打印头以高的精度、高的质量和高的速度的方式来打印。 The image can be used directly in non-contact printing head with high accuracy, high quality and high speed manner to print. 这些墨水还具有适用于安全标志的其它优点,因为它们可以含有渗透性溶液使得荧光的成分可以有选择性地渗透到纸张中。 These inks also have other advantages applicable to safety signs, because they may contain a solution such that the permeability of the fluorescent component can selectively penetrate into the paper. 该选择性的渗透对安全标志的荧光成分提供了摹拓和伪造支票的抵制。 The selective permeation of fluorescent ingredient safety signs provide rubbings and forged checks to resist.

用于邮票邮资所使用的喷墨打印的另一问题是现在由于缺乏同时适用于邮资和机读的喷墨技术的墨水功能而受限于某些范围。 Another issue postage stamps used for ink jet printing ink is now due to lack of features also apply to postage and machine-readable ink jet technology and limited to certain areas.

邮资服务采用在邮戳中印刷信息,以用于安全和标志目的的以及处理邮件。 Postal service postmark printed using the information for the purpose of security and sign and mail handling. 特别是,USPS的基于信息的邮戳以一个两维条形码的形式包含着高密度、可变化、加密保护的信息。 In particular, USPS Information Based Indicia information in the form of a two-dimensional bar code contains a high density, can be varied, cryptographically protected. 为了能采集这个信息,邮资扫描设备必须有效检测和读取基于信息的邮戳,在各种基底上所印刷的邮资邮戳必须在反射方面具有足够的对比度,从而使邮戳能够机读。 In order to collect this information, postage scanning equipment must effectively detect and read the information on the postmark on various substrates printed postage postmark must have sufficient contrast in terms of reflection, so that the machine can read the postmark. 例如,在暗的基底上,如反射比在0.45至0.6之间的牛皮纸信封,采用红色墨水就很难获得所需要的对比度。 For example, on a dark substrate, such as a reflectance ratio is between from 0.45 to 0.6 of manila envelope, using red ink is difficult to obtain desired contrast. 因此,就非常需要能印刷呈现出高对比度的安全标志,最好是黑色以及同时具有红色的荧光。 Therefore, we need to be able to print exhibit very high contrast safety signs, preferably black, and also has a red fluorescence. 然而,红色荧光墨水通常并不具有光学特性识别(OCR)设备、条形码阅读机和其它类型的机器视觉技术能可靠阅读的足够对比度。 However, the red fluorescent inks generally do not have optical characteristics recognition (OCR) equipment, bar code readers and other types of machine vision technology to reliably read a sufficient contrast. 这些系统一般在频谱的红色区域中具有照明和检测系统。 These systems typically have lighting and detection systems in the red region of the spectrum.

荧光安全性能的一个缺点是很多类的商品化有机发光化合物。 One disadvantage of fluorescent security performance organic light-emitting compounds are commercially available in many types. 普通的例子是发光的和商品化颜料荧光的材料和墨水。 Common examples are glowing fluorescent pigment and commercialization of materials and inks. 邮戳的伪造复制就只能希望所采用的正是材料的基底具有能发射出类似颜色光的发光物质。 Postmark forged copy can only hope that it is used in the base material has a light-emitting substance can emit light of a similar color. 于是,这就有利于提供具有独特光学特性并不能采用简单的商品材料来模仿的发光墨水。 So, which is conducive to providing a unique optical properties and can not be used to simulate a simple commodity materials emitting ink. 本发明提供了具有这类独特光学特性的墨水。 The present invention provides an ink having such unique optical characteristics.

此外,在基于数字邮戳的邮件安全系统中,如果在多个邮件上复制和产生邮资邮戳,就很难使得邮资服务器可以知道在具有相同邮戳的邮件中那一个具有最初的邮戳。 In addition, e-mail security system based on digital postmark, if the replication and produce postage indicia on multiple e-mail, it is difficult to make postage mail server can know that the same one with a postmark of the original postmark.

于是,提供一种在邮件上附加一个安全且该安全随后可以用于在正当付费的邮件和没有付费的邮件之间识别的方法和系统是有利的也是需要的。 Thus, to provide a secure and that an additional safety can then be used in a method and system identification between legitimate mail and paying no paid mail is advantageous also needed on the message.

发明内容 SUMMARY

发明详述图1a说明了邮件1具有邮票或邮戳12,宣传信息14,邮件地址18和退回地址16。 DETAILED DESCRIPTION OF THE INVENTION Fig. 1a illustrates a mail with a stamp or postmark 12, 14 promotional information, e-mail address and return address 18 16. 为了能确认邮票或邮戳12是有效的还是非法制造的复制品,较佳的是邮票或邮戳是采用特殊的墨水来印刷。 In order to confirm the stamp or postmark 12 is valid or illegal manufacture of copies, preferably stamp or postmark is using a special ink to print. 特别是,该墨水是能够吸收可见光并且一旦紫外光激发时会产生荧光发射。 In particular, the ink is capable of absorbing visible light and generates fluorescence emission when excited by UV light once. 在以下的表1和表2中列出了两例特殊墨水。 Two cases are listed in the following special ink Tables 1 and 2 below. 因为该墨水能够吸收可见光,所以可以在邮局采用图像扫描仪来采集可见光的图像,该图像扫描仪通常是用于采集以常规墨水所制成的邮戳图像。 Since the ink is capable of absorbing visible light, it is possible to use the image scanner in the post office to capture visible light image, the image scanner typically used to collect indicium image made of a conventional ink. 此外,USPS也使用可以检测红色荧光的邮资机器。 In addition, USPS also be detected using the red fluorescent postage machine. 于是,可以在不改动现有的有效设备的条件下,USPS能够处理采用包括OVD性能的墨水(称之为OVD墨水)来印刷邮戳。 Thus, changes may be made without the conditions existing valid device, USPS OVD performance capable of processing using an ink comprising (called OVD ink) to print indicium. 邮资的邮戳和邮资机器都已经开发成功,并能够采用数字印刷特别是喷墨印刷。 Postmark postage and postage machines have been developed, and in particular to adopt digital printing inkjet printing. 于是,较佳的是,OVD墨水可以用于包括喷墨打印机的数字打印机。 Thus, preferably, OVD ink jet printer may be used include a digital printer.

图1b说明了非邮件的物件30,例如,票据、标签、流动券、支票、证书、身份证章或证书、文件或其他相类似的。 Figure 1b shows the non-mail items 30, for example, notes, labels, mobile coupons, checks, certificates, identification badges or certificates, or other similar document. 例如,安全标志可以在非邮件物件30提供安全标志,如,一个或多文字数字符号34,一个图形设计32,一个目标36的相似形,一个条形码38。 For example, safety signs safety signs can provide 30 non-mail items, such as one or more alphanumeric symbols 34, a graphic design 32, a target 36 similar figures, a bar code 38. 可以采用类似于在邮件上的安全标志的方法进行比较安全标志所产生的可见光图像和荧光图像来确认在非邮件物件30上的安全标志。 Can be confirmed in the non-mail items were similar to 30 safety signs visible and fluorescence images generated by comparing safety signs safety signs in the mail on the approach to take.

本文所使用的术语“光敏光学可变(POV)安全标志”是指印刷的视觉上黑色或深灰色的携带着可机读信息且当采用较短波长的光激发时以特殊的波长范围发出荧光的标志。 As used herein, the term "photosensitive optically variable (POV) security flag" means a printed visually black or dark gray machine-readable information carrying and when using the shorter wavelength excitation light wavelength range in particular to fluoresce sign. POV安全标志在整个可见光谱范围内呈现出可见光谱的吸收,且该光谱范围包括了可见光谱中的红色区域,但对典型的自动扫描系统来说,红色的墨水是不可见的。 POV security mark in the entire visible spectrum exhibits absorption in the visible spectrum, and the spectral range of the visible spectrum including the red region, but for the typical automatic scanning systems, the red ink is invisible. 这些墨水就可以在诸如牛皮纸或马尼拉纸的深色纸上获得可接受的PCS(印刷的对比信号)。 These inks can be obtained in an acceptable dark paper such as kraft paper or the manila the PCS (print contrast signal).

图2a和2b显示了包括数据阵列条形码的POV安全标志的机器扫描图像22和24。 Figures 2a and 2b show the machine comprises a scanned image of the bar code data array POV safety signs 22 and 24. 在POV安全标志中可以使用诸如一维条形码、其它类型的两维条形码、可印刷的水印,或OCR特性的任何其它符号。 In POV security flag may be used such as a one-dimensional bar code, other types of two-dimensional bar code, any other printable watermark symbol or OCR features. 反射扫描的图像22是采用可见光来照明该标志所获得的。 Reflection image 22 is scanned using visible light to illuminate the sign obtained. 黑色模式的低反射率使得扫描图像的深色区域对应于安全标志的印刷区域。 Low reflectance black pattern makes a scanned image of dark areas correspond to the printed area of safety signs. 以荧光扫描的图像24是通过观察在紫外(UV)照明下可见红色荧光的发射而获得的。 Fluorescence image 24 is scanned by observation under ultraviolet (UV) illumination visible red fluorescence emission obtained. 扫描的图像24显示了当采用UV光照明时安全标志发射可见光并且使得在扫描图像中的发光区域对应于所印刷的区域。 24 shows a scanned image when illuminated with UV light and emit visible light such that the security mark in the scanned image of the light emitting region corresponding to the printed area. 比较图像22和24显示了荧光图像时发射图像的负像,即,在两个图像之间存在着较强的负相关性。 Comparison image 22 and 24 show the emission fluorescence image as a negative image, i.e., between two images exist a strong negative correlation.

荧光图像22可以在紫外光的激发下由邮票或邮戳12或者其它安全标志14、16、18、32、34、36产生。 22 fluorescence images can 14,16,18,32,34,36 produced by stamp or postmark 12 or other safety signs at UV excitation. 图2b说明了当采用可见光照明安全标志时由相同安全标志所产生的可见图像24。 Figure 2b shows the visible image 24 when using visible light by the same safety signs safety signs produced. 图2a和2b只是作为范例,因为采用OVD墨水印刷的邮票和邮戳12或者其它安全标志14、16、18、32、34、36都可以具有吸收可见光以及在紫外光的激发下产生荧光发射的功能,并且荧光图像22和可见图像24是相互相关的。 Figures 2a and 2b only as an example, because the use of OVD ink stamp and postmark printing or other security flag 14,16,18,32,34,36 12 can have a visible light absorption and fluorescence emission upon excitation by ultraviolet light functions , and the fluorescence image 22 and a visible image 24 is associated with each other. 如果邮票和邮戳12或者其它安全标志14、16、18、32、34、36采用复制设备(例如,影印机)被非法复制时,通常是难以获得荧光图像的。 If the stamp and postmark 12 or other safety signs 14,16,18,32,34,36 using reproduction apparatus (e.g., copy machine) from being illegally copied, is usually difficult to obtain a fluorescence image. 为了能确认邮票和邮戳12或者其它安全标志14、16、18、32、34、36的有效性,就有可能通过荧光图像22和可见图像24的视觉比较来发现它们之间的匹配。 In order to confirm the 12 stamps and postmarks or other safety signs 14,16,18,32,34,36 effectiveness, it is possible to find a matching comparison between them visible by fluorescence image 22 and 24 of the visual image. 然而,较佳的是,采用比较的设备来比较图像22和24,正如图3所示。 However, preferably, using an image comparison device to compare 22 and 24, as shown in Figure 3.

对于诸如邮资付费的数值计量的应用和其它安全应用来说,其法律特征是很重要的。 For applications and other security applications, such as postage-paid value measured in terms of its legal characteristics is very important. 荧光墨水的其它安全应用包括安全纸和文件。 Fluorescent ink other security applications, including security paper and documents. 于是,即使去除了可见的深色颜色之后,所保存的荧光图像104依然可以提供印刷内容的法律证据。 Thus, even after removing the visible dark color, the stored fluorescence image 104 can still provide legal proof print content. 在本发明中,在荧光和非荧光部分之间渗透上的差异提供在已经去除了可见部分之后依然存在着标志的法律证据。 In the present invention, between the fluorescent and non-fluorescent portion provided on the differences in penetration has been removed after the visible portion there are still legal evidence signs.

采用通用黑墨水印刷的安全标志是容易复制和改动的。 Black ink is printed using a common safety signs are easy to copy and changes. 数据的真实性的确认,例如,通过确认在条形码的数据中所包括的加密数字签名就能够检测数据的改动,而不能检测复制的数据。 Confirmation of the authenticity of the data, e.g., by confirming the encrypted digital data in the barcode included in the signature data changes can be detected, the copied data can not be detected. 本文所披露的可机读荧光墨水提供了防止不可检测的复制的屏障。 Disclosed herein may provide a machine-readable fluorescent ink barrier preventing replication undetectable. 通常,荧光是附加在有色的墨水中,以增加其亮度。 Typically, fluorescence is added to colored inks to increase the brightness. 现在还没有普遍的商业动机来制造用于一般用途视觉深色的荧光墨水,从而使得机读的荧光墨水可以成为用于特殊用途的唯一可控制的供应物件。 There is no universal commercial incentive to manufacture for general use visual dark fluorescent inks, making the machine-readable fluorescent ink supply may become objects for special purposes only controllable.

这些POV安全标志可以采用数字打印、热传递或电子摄影术的方法来产生。 These POV safety signs can be used digital printing, heat transfer, or electronic photography method to generate. 特别是,可以采用本文所披露的水性墨水通过喷墨打印来制成。 In particular, aqueous ink may be used as disclosed herein is made by ink jet printing.

图3说明了适用于确认安全标志12的系统。 Figure 3 illustrates the system used to confirm the safety mark 12. 正如图3所示,可见光源50可以用于提供在安全标志12上的照明光60。 As shown in Figure 3, the visible light source 50 may be used to provide illumination light 60 in the security label 12 on. 采用来自安全标志12的反射光70,反射图像扫描仪80可以采集可见光图像24。 Using reflection of light from the safety signs 12 70 80 reflected image scanner can capture the visible image 24. 类似,紫外光源52可以用于提供在安全标志12上的照明光62。 Similarly, the ultraviolet light source 52 may be used to provide the safety mark 12 of the illumination light 62. 采用来自安全标志12的荧光发射72,荧光图像扫描仪82就能够采集荧光图像22。 Fluorescence emission from safety signs 12 72 82 fluorescence image scanner will be able to collect the fluorescence image 22. 较佳的是,控制机制54可用于调整照明源50和52的照明以及图像扫描仪80和82所扫描的图像。 Preferably, the control mechanism 54 may be used to adjust illumination source illumination and image scanners 50 and 52 80 and 82 the scanned image. 反射图像扫描仪80和荧光图像扫描仪82可以分别和连续采集各自的图像。 Reflection fluorescence image scanner 80 and 82 image scanner can capture continuous images of each separately. 然而,当采用适当的滤波器和光学部件将反射光70和荧光发射72直接引导到各自的图像扫描仪时,也有可能同时采集到可见光图像24和荧光图像22。 However, when using an appropriate filter and the optical member 70 and the reflected light fluorescence 72 directly into the respective emission image scanner, it is possible to simultaneously capture the visible image 24 and fluorescent image 22. 较佳的是,将荧光图像22和可见图像24存储与一个图像存储部件84,从而能处理和比较这些图像。 Preferably, the fluorescence image 22 and a visible image 24 is stored with an image storage section 84, so that it can handle and compare these images. 正如所示,表示荧光图像22的信号和图像数据86和表示可见图像24的信号和图像数据88都可以发送到图像处理和相关设备90。 As indicated, represents the fluorescence image signal and the image data 86 and 22 represent a visible image signal and image data 24 of 88 can be sent to the image processing apparatus 90 and associated. 因为荧光图像22是可见图像24的“负”像,并且这两个图像是不同颜色的,较佳的是,在比较图像数据86和88之前,先处理图像数据86和88。 Because the fluorescence image 22 is visible image 24 of "negative" image, and the two images are of different colors, preferably, in a comparison image data 86 before and 88, the first processed image data 86 and 88. 例如,软件程序92可以用于计算表示在荧光图像22和可见图像24之间相关性的数值94。 For example, the software program 92 may be used to calculate the correlation values represent between 24 and fluorescent image 22 visible image 94. 该相关性数值94随后与预先设定的数值96相比较,以确定荧光图像22和可见图像24是否是采用印刷安全标志12的OVD墨水的结果。 The correlation value of 94 followed by 96 as compared with a preset value to determine the fluorescence image 22 and image 24 is visible is the use of safety signs results OVD printing ink 12. 例如,只有如果相关性数值94是等于或大于预定的数值96,才能假定安全标志12是采用OVD墨水合法产生的。 For example, if only the correlation value 94 is equal to or greater than the predetermined value 96, 12 can be assumed that the security mark is generated using OVD ink legitimate. 应该注意的是,因为OVD墨水的荧光发射可以限制于一定的波长范围,所以就有可能使用带通滤波器,只允许在波长范围内的荧光发射72能够到达荧光图像扫描仪82。 It should be noted that because the fluorescence emission OVD ink can be limited to a certain range of wavelengths, it is possible to use a band pass filter, allowing only fluorescence in the wavelength range of the fluorescence emission 72 can reach the image scanner 82. 正是如此,非法复制所产生的荧光发射就能被滤波去掉。 Is the case, the fluorescent emission generated by the illegal copy can be filtered to remove. 应该注意的是,以上结合图2a和3所进行的讨论只是涉及来自邮票或邮戳12所获得的荧光图像和可见图像。 It should be noted that the above discussion in connection with Fig. 2a and 3, carried out involving only the fluorescence image from a stamp or meter 12, and the obtained visible image. 应该理解的是,荧光图像和可见图像也能从任意安全标志中获得。 It should be understood that the fluorescence image and the visible image are also obtained from any safety signs. 此外,较佳的是,在使用图像扫描仪进行扫描获得安全标志的图像时,有可能使用数字摄像机或视频摄像机来获得图像。 In addition, preferably, when using an image scanner for scanning an image to obtain safety signs, it is possible to use a digital camera or a video camera to obtain an image. 也有可能使用胶片摄像机来获得图像,以及使用转换设备将胶片图像转换成数字图像,以便于处理。 Also possible to use a film camera to acquire images, and using a conversion device film images into a digital image, in order to deal with.

图4说明了使用OVD墨水制成的安全标志的物件确认的整个系统。 Figure 4 illustrates the overall system security flag OVD ink objects made of confirmation. 例如,该系统可以与现有的邮资确认系统组合在一起。 For example, the system can be combined with existing postage validation system. 正如图4所示,该系统1包括邮资计量仪,它具有用于在邮件10上印刷邮资邮戳和其它邮件或非邮件相关信息的打印头102。 As shown in Figure 4, the system 1 comprises a postage meter having a printhead for printing postage indicia on mail 10 and other mail or e-mail-related information 102. 替代邮资计量仪100,打印机112可以与个人计算机110相连接,以用于打印信息或图像。 Alternatively postage meter 100, the printer 112 can be connected to a personal computer 110, for printing information or images. 当数据中心200接受到邮件时,加密信息确认系统210可以用于从其包含的加密信息中确认邮资邮戳12。 When the data center received 200 e-mail, encrypted information system 210 can be used to confirm the postage indicia 12 to confirm the information contained in its encrypted. 此外,安全标志确认系统200可以用于从其所获得的荧光图像和可见图像来确认安全标志。 In addition, safety signs confirm that the system 200 may be used fluorescence images and visible images obtained from it to confirm the safety signs. 较佳的是,打印头102是一个喷墨打印头,并且打印机112是以喷墨打印机,使得它们可以使用如表I和表II所示的OVD墨水来打印安全标志。 Preferably, the print head 102 is an ink jet print head, and the printer 112 is an ink jet printer, the ink OVD so that they can be used as shown in Tables I and II to print the security mark.
