Definitions
- This invention relates to the detection of counterfeit objects.
- it relates to the detection of counterfeit objects by detecting unauthorised material of which the object is made or on which it is printed or otherwise formed.
- counterfeit objects in particular, counterfeit bank notes is continually increasing on the back of continuing improvements in printing technology, particularly colour printing.
- Counterfeit notes are now being made which appear, to the unaided eye, virtually indistinguishable from a genuine note.
- Bleached paper includes chemical components which fluoresce when exposed to ultraviolet radiation, that is, the molecules in the composition of the paper are excited and emit light at a longer wavelength which peaks in the band of from 400 to 500 nm. Because wavelengths of 300 to 400 nm generally lie outside the spectral region of the human eye and because wavelengths of from 400 to 500 nm lie within the spectral region, the phenomena of fluorescence allows some counterfeits to be detected with the human eye.
- This process can be automated with the use of electronics by providing a sensor and a comparator which compares the intensity of the fluorescent light sensed with a reference level so as to provide an indication as to whether the paper is likely counterfeit or not.
- a sensor and a comparator which compares the intensity of the fluorescent light sensed with a reference level so as to provide an indication as to whether the paper is likely counterfeit or not.
- US-A-4 296 326 discloses apparatus for checking documents such as banknotes, in which the apparatus is arranged to convey a document on drums past detectors. This apparatus also carries out a measurement of fluorescence of the document when the latter is illuminated by ultraviolet radiation. In addition, further tests are performed. One such further test involves detecting reflected ultraviolet radiation. This is performed in order to determine whether the document carries a particular type of watermark. The test involves taking a reflectivity measurement in one area of the banknote (outside the area where the watermark is expected), and comparing this with measurements within a watermark area. Thus, the ultraviolet reflectance test is limited to detecting only variations in reflectivity across the banknote, and each measurement has to be performed at specific, known areas of the banknote.
- the apparatus for detecting counterfeit objects, the apparatus comprising:
- the invention also provides a method for determining the genuineness of a test object using counterfeit detection apparatus, the method comprising illuminating the test object with ultraviolet light and determining genuineness on the basis of the fluorescence of the test object and the ultraviolet light reflected therefrom, characterised in that the testing operation initially involves the manual positioning of the detection apparatus and test object relative to each other, and in that the genuineness decision uses an ultraviolet reflective measurement having a magnitude which is determined by the absolute reflectivity of the test object and not by the relationship between the reflected light and a reference light level dependent on the test object.
- Figure 1 shows apparatus for irradiating a bank note with light and then measuring the amount of fluorescent light and reflected light.
- the apparatus includes a generally rectangular container 100 having a window 102 against which a bank note to be sensed can be placed.
- an elongate light source 104 for producing light in the 365 nm region and directing it through the window 102.
- two photo diodes 105 and 106 spaced apart from one another but angularly inclined so that their optical axes intersect generally at the outer surface of the window 102.
- Each photo-diode 105 and 106 is mounted on the floor of a respective tubular opaque housing 108 and 110.
- the inner walls of the housing are lined with reflective material to increase the sensitivity of the photo-diodes.
- a 365 nm band pass optical filter 112 covers the housing 108 and a 450 nm band pass optical filter covers the housing 110.
- the lamp 104 is surrounded on three sides by reflective material 116 for example aluminium foil which reflects light generally in the direction of the window 102 to concentrate the light at the window.
- reflective material 116 for example aluminium foil which reflects light generally in the direction of the window 102 to concentrate the light at the window.
- the reflective material is so positioned around the light source that the optical plane of the light directed at the window, makes the same angle with the window as do the optical axes of the photo detectors in a manner to ensure that the photo-detectors receive the maximum fluorescent and maximum reflected light from any bank note placed on the window 102.
- the window 102 is provided by a glass plate which reflects some of the light received from the source 104 back to the photo-diode 105.
- the light is principally reflected back from the glass-air boundary of the plate and typically is around 8% of the light directed at the glass plate.
- the amount of reflected light at 365 nm is usually fairly small and so typically the amount of reflected light will increase from 8% to a value in the range of from 12 to 18%.
- the light reflected from the plate when no bank note is present can be used as a reference level to compare the degree of reflection with when a bank note is present.
- the amount of fluorescent light emitted by a counterfeit bank note is generally several orders higher than the amount of light emitted by a genuine bank note and so any degradation of the light source 104 makes little or no difference to the detection of fluorescent light.
- An electronic processor (not shown but which will be described in more detail hereinafter) monitors the light received by both photocells with the lamp 104 switched on. In the absence of a bank note on a window the photocell 105 will provide a steady state output. As soon as a bank note is placed on the window the output from the photocell 105 will rise and a trigger signal is then generated to activate two measurement circuits for measuring the outputs of the two photocells 105 and 106.
- the measurement circuits provide readings which can be displayed by a display device 126, and a decision circuit will, in response to the readings, activate one of two optical indicators 122 and 124 respectively indicating that the bank note is genuine or counterfeit.
- a printer (not shown) may be provided to record the values displayed by the display device 126.
- the apparatus is automatically activated by the placement of a bank note on the window to determine whether the bank note is genuine or counterfeit.
- Each photocell 105 and 106 feeds a respective trigger circuit 130 and 132 for detecting a rapid change in signal for example as a result of a bank note being placed on the window.
- Either or both trigger circuits 130 and 132 feed a signal to an actuator 134 which actuates two measurement circuits 136 and 138 (for example by supplying power to them or deactivating inhibitors which inhibit their operation).
- a delay circuit 140 deactuates the measurement circuits 136 and 138 after a short measurement period.
- a first comparator 142 compares the output of the photocell 105 with a reference value stored in a store 144 and if the detected value exceeds the reference value, an output is generated which is fed simultaneously to the gates 146 and 148.
- the signal stored in the store 144 is derived from the photocell 105 during the quiescent state of the apparatus.
- the output of the photocell 105 is amplified by an amplifier 150 by a factor of between 25% and 50% and stored in the store 144.
- the amplifier 150 is inhibited so that the store 144 only stores the quiescent value of reflected light.
- a comparator 152 compares the output of the measurement circuit 138 with a reference value 154 and when the reference value is exceeded generates an output signal which is fed to the two gates 146 and 148.
- the gate 146 responds when a genuine note is detected to energise the indicator 122.
- the gate 148 responds to energise the indicator 124 when a counterfeit note is detected.
- the actual values at the outputs of the two measured circuits 136 and 138 are fed to the display 126 for display thereby.
- the apparatus is advantageously shielded by a cover which provides a slot through which a bank note can be inserted onto the window.
- the light source can be modulated at a selected frequency and the outputs of the photo diodes demodulated at the same frequency to eliminate the effects of ambient light.
- rs (Ps/Pr) *r g /(1-r g ) 2
- Ps is the reflected portion of the irradiating signal from the specimen
- Pr is similarly that portion returned from the glass plate to be used as a reference
- r g is the coefficient of reflectance from the glass plate.
- UV reflection from a bank note varies with the degree of soiling. It may be possible to measure the degree of soiling and to compensate by adjusting the reference values stored accordingly.
- the apparatus shown in Figure 5 measures both fluorescent light and reflected light using a single monitor to determine whether a bank note is counterfeit or genuine.
- the apparatus comprises an ultraviolet (UV) lamp 2 which is preferably mounted in a hand-held scanning unit.
- the UV lamp 2 is arranged to emit radiation at a frequency which is known to cause bleached paper to fluoresce.
- a detector 3 is arranged to receive both fluorescent and reflected radiation from a bank note 1 but not directly from UV lamp 2 without being reflected.
- the monitor may be a photo-diode or phototransistor, for example, sensitive to the appropriate light frequency or frequencies.
- the monitor should be sensitive to fluorescent light in the 400-500 nm range and to reflected ultraviolet light in the 300-400 nm range so as to be sensitive to counterfeit notes of bleached paper which fluoresce or counterfeit notes which don't fluoresce but because they are counterfeit often have a higher reflectance to ultraviolet light than genuine notes.
- An electrical signal is applied from monitor 3 to one input of a comparator 4.
- a second detector or monitor 5 is arranged to receive UV radiation directly from lamp 2.
- the signal from this is first amplified by an amplifier 6 and applied to a resistor 7 the other end of which is earthed.
- Resistor 7 forms part of a potentiometer, the slider connection of which itself is applied as a second input to comparator 4.
- the slider can be set to provide a threshold value representing a predetermined proportion of the voltage which is proportional to the UV intensity.
- the comparator 4 is arranged to output a signal if the signal received by the monitor 3 is greater than or equal to the set detection threshold.
- the threshold When the threshold is reached it means that a certain proportion of the light impinging upon note 1 has been reflected or re-emitted as fluorescence and therefore it is assumed that the note is counterfeit.
- the signal from the comparator 4 is applied through a low pass filter (for example an RC filter 8,9 as shown in Figure 5) to a timer 10.
- This timer produces a pulse of, for example, approximately one second which actuates a buzzer 11 and a visual alarm in the form of an LED 12.
- buzzer 11 and LED 12 are mounted in parallel between an output line from timer 10 and ground.
- Other types of alarm, whether audible or visual or both can be used in addition or as an alternative to those shown.
- the output pulse from timer 10 may also be applied to a line driver 13 which is adapted to provide a suitable signal for application to a management system.
- This management system may be used to provide a warning to a remote control position, such as a manager's or security office in a shop for example, that a counterfeit note has been identified.
- a remote control position such as a manager's or security office in a shop for example.
- the line driver may, in one example, provide TTL signals.
- the apparatus is most preferably configured as a hand-held scanning unit and one, non-limiting example of a suitable housing in which the apparatus may be mounted is shown in Figures 6 to 8.
- the unit comprises a head 17 in which the UV lamp 2 is mounted to illuminate an object placed underneath the head.
- a handle 18 is preferably shaped with a series of ridges for example to facilitate a good hand grip.
- Power for the apparatus is provided through a mains lead 19 which can be from a mains supply, from an adjacent till or EPOS unit, or by other means. It may alternatively be possible for the apparatus to be powered by batteries, which may be rechargeable batteries, for true portability.
- a basic on/off switch 20 is provided which enables lamp 2 to be illuminated and therefore the detection apparatus to function only when the switch is depressed by a thumb for example when the unit is being held. If this configuration is adopted then the unit is arranged to operate only in the scan position.
- the signal to a remote control or monitoring station such as a security office, may be transmitted by mains-born signalling. This may be achieved by applying pulses of known frequency onto the mains. If different frequencies are applied by different units then an operator at the remote position, when receiving a signal indicating a counterfeit note, will know which scanning unit has identified that note.
- the unit may be temporarily mounted in position, eg by a suitable bracket mounting, when in use and/or when 'dormant'.
- the portable and adaptable nature of the unit enables great versatility of use in different environments and situations and with different attachments thereto.
- the detection circuitry is effectively only operated when the ON/OFF switch is used to actuate the lamp, thereby minimising power consumption and reducing false readings from objects other than those desired to be tested.
- FIG. 9 An alternative hand-held scanning unit in the form of a wand is shown in Figures 9 and 10. As shown, the wand has a cylindrical housing 58 having a switch 60 on one side and an ultraviolet lamp 62 on the opposite side. A sensor 64 is located adjacent the lamp 62. The unit operates in a similar manner to the unit of Figures 6 to 8.
- the counterfeit objects may be other than bank notes and could be any object, the authenticity of which relies to some extent on the type of paper or other material it is formed from or printed on.
- the genuine article may glow under UV light, in which case the apparatus can be suitably modified, eg by reversing the input connections to comparator 4 so that a signal less than a threshold level actuates an alarm.
