Definitions
- the invention relates to an identification element with at least one signature according to the preamble of claim 1, to an identification system according to the preamble of claim 10 and to a method for producing the identification element according to the preamble of claim 17.
- Identification systems are used in the most diverse fields. In this application, the main focus is on the security area in which identification elements or systems are to be found as far as possible in the form of keys and locks for the protection of objects or information against unauthorized access. In principle, however, the invention can also be transferred to other areas, such as in the production area for the identification of objects or tools or in product piracy.
- the key may be present in an object, for example a code card, or consist of a code, e.g. a secret number. If the electronic key is correct, it triggers only an electrical or hydraulic unlocking of the lock, for example by means of a simple motor control.
- the electronic keys or codes can be stored in a central computer, which is connected to the electronic lock. For example, it is possible to determine when or by whom the key was used, which is particularly important for time recording systems.
- Electronic keys such as a code card
- Electronic keys are sensitive to external influences, such as e.g. Temperature or mechanical effects.
- strong magnetic fields can lead to the destruction or loss of the electronic key or stored electronic coding or information.
- a key in the form of a code e.g. a secret number, it may be forgotten.
- the lock cylinder is a magnetic flux, which is generated for example by a permanent magnet. Furthermore, the lock cylinder on movably arranged query elements which are moved and aligned by means of a magnetic force.
- the key is made of a material with a certain magnetic resistance and has areas with changed lower magnetic resistance. This forms a "magnetically acting coding".
- the interrogation elements align with the areas of lower magnetic resistance, thereby initiating an unlocking mechanism.
- a disadvantage of the magnetic locks described is that a strong magnetic field emanating from the key or the lock, which can affect or destroy magnetic cards, for example. Furthermore, a permanent magnetic field is required either in the key or in the lock to ensure the function.
- the present invention seeks to provide an identification element, an identification system and a method for producing the identification element, which are not copied or only with appropriate knowledge and considerable technical effort.
- This object is achieved by an identification element having the features of claim 1, an identification system having the features of claim 11 and a method for producing the identification element having the features of claim 17.
- identification element is an object or an object that bears a unique identification feature linked to a specific identity, using very different objects, which can be of material as well as material For example, a finger or a fingerprint uniquely identifies a specific person, and with the help of identification systems, an unambiguous association between the designator and the designated person takes place for these particular objects.
- signature is, in contrast to the identification element, a specific property and / or a specific feature of a particular object, which can be determined and / or read by means of suitable methods.
- the signature is associated with the item so that it can be uniquely identified and assigned, and it is also possible that an item has several signatures that can be determined by various methods.
- the signature is a” fingerprint "of the item a way determined by a certain method and can be determined, for example, in the form of any curve course.
- An object also provided with a signature in this sense would be a key.
- the key is uniquely determined by a signature in the form of a key bar, which is coded by the individual prongs and can be read out by means of a suitable method, a corresponding lock.
- coding element An encoding element is part of a coding which is reflected in and influences a signature
- coding elements are formed as embossing processes that entail frozen mechanical stresses
- individual coding elements influence the signature A and other coding elements the signature B.
- the Signature A with a specific, eg an electrical, method is readable, while the signature B with another method, eg a mechanical method, can be read out.
- a classic key has a mechanical signature, in the form of a key bit.
- the key introduced, which cause a second electromagnetic signature.
- the key receives in addition to its mechanical signature or to its mechanical key bit an electromagnetic signature or an electromagnetic key bit in the form of frozen mechanical stresses. This adds another level to the security of the key.
- embossing processes or embossing are to be understood as all processes which lead to changes in the material structure, for example a metal grid, or to frozen mechanical stresses. This also applies to embossing machines. If this application refers to embossing processes or embossing machines, all operations or machines are always meant which lead to frozen mechanical stresses. In this sense, for example, it is also possible to use optical methods, e.g. be embossed by a laser process. By selective heating also frozen mechanical stresses can be generated. Also conceivable are chemical processes which bring about such a change in the material structure or trigger a change in the atomic structure. Other mechanical methods such as, for example, a method of twisting, stretching or distortion are conceivable as embossing processes in this sense.
- randomness level refers to various types of randomness algorithms that summarize arbitrariness or variability. This term may not necessarily be a local or spatial level, but rather parameters Several random planes can be superimposed in such a way that they form a signature with their characteristics: For example, a codeword can consist of a random plane, the lowercase Latin letters If these two random levels are superimposed or combined, the result is an analogous codeword that contains both letters and numbers, but which is not recognizable or perceptible. The length of the codeword or the number of letters or numbers would be eb in this sense enso a random plane superimposed on the other random planes.
- the code word in this example could therefore be "e3t5j4m47.”
- Random levels can be very different depending on the coding and can vary greatly. the.
- embossments for example at different locations, the duration of the embossings, the depth of the embossments, the embossing temperature, the preceding temperature treatment of the object to be embossed and the order of the embossments as random levels are also valid understand that can be superimposed with each other. It is conceivable that a coding or individual coding elements are based on a plurality of superimposed random planes and form a signature with their characteristics, which can be determined, for example, in the form of an arbitrary curve course.
- the invention describes an identification element and an identification system, comprising the at least one identification element and at least one identification console with a corresponding electronic reading unit.
- the identification element has at least one signature.
- the signature comprises at least one coding which can be generated by means of a random generator and optionally at least one known coding, which in turn is formed by frozen mechanical stresses and comprises at least one coding element.
- the advantageous generation of the coding by means of a random generator results a large number, in the range of several hundred billions, of possible coding and thus increased security with regard to copying the identification element.
- a known coding it is possible, for example, to encode any fixed bit-coded number into the signature.
- a gradual coding of the signature is also conceivable, in which the signature comprises a combination of known codings and codings which can be generated by means of a random number generator.
- the signature has codings which can be generated exclusively by means of a random generator and possibly known codings.
- the coding that can be generated by means of the random generator also has at least one random plane.
- the coding itself is formed by frozen mechanical stresses which penetrate into the depth of the identification element. Thus, the coding is closely linked to the identification element and can be very difficult to decouple from this again.
- the at least one encoding that can be generated by means of a random generator and optionally the at least one known coding has a plurality of coding elements, which results in increased security.
- the identification element is advantageously formed by a metal body, preferably made of stainless steel, and has the shape of a rod, preferably a round rod. This allows a simple and cost-effective production of the identification element and protects the identification element with regard to weather conditions, high temperatures and mechanical effects. Also conceivable are other forms of the identification element, such as the shape of a classic key.
- the signature is an electromagnetically effective signature.
- the signature itself is not magnetic. By using an electromagnetically effective signature, this is initially not open and can not be recognized by a human without further aids, as is the case, for example, with a key or the corresponding key bit.
- the electromagnetically effective signature thus corresponds to an "electromagnetic key bit" of the object which uniquely identifies it, but an electromagnetically effective signature can be read out by suitable methods such as an inductive vector analysis according to the earlier German patent application DE 10 2014 007 491 A1 there is a contactless scanning of the signature, which has a positive effect on the wear of the identification element.
- the random plane is advantageously superposed with at least one other random plane.
- the identification element has at least one coding region in which coding elements of the coding are at least partially arranged.
- the coding has at least one, preferably a multiplicity of coding elements.
- adjacent or integrated into the coding area is a signal zone which is recognizable by a reading unit as the end of the coding area. This ensures that the complete identification element or the complete coding area or the complete coding is scanned.
- the coding on the identification element for a human without further aids not palpable, visible or perceptible.
- the coding information is not available. This prevents the coding can be spied by a photo or wax print of the identification element, read and imitated.
- the identification system comprises a signature having identification element and an identification console for identifying the identification element and / or for actuating a mechanism, in particular an opening / closing mechanism.
- the identification console has at least one reading unit and preferably a decoding unit.
- the decoding unit can, in principle, be located everywhere, in particular also outside the identification console.
- the coding that can be generated by means of the random generator has at least one random plane.
- the reading unit is designed as a non-contact and electromagnetically operating reading unit.
- the identification console is adapted to the shape of the identification element.
- An advantage here is a simple detection of the corresponding identification element with the appropriate identification console.
- use of the identification console is only possible by means of identification elements which have the correct geometry of the identifier. have onselements. Otherwise, the identification element would not fit in the identification console, which further increases the security of the entire identification system by a further step.
- Different positions, movements and / or orientations of the identification element can be detected by the reading unit independently of the starting position of the identification system relative to the reading unit. The detection is also independent of the initial position of the identification element, in which it is introduced into the identification console. This advantageously serves for rapid detection of the identification element and for easy operation of the entire identification system.
- a sequence is understood to mean a sequence of different movements or orientations of the identification element, for example a rotation by 40 degrees counterclockwise and then by 90 degrees in the clockwise direction. This makes it possible to emulate the mechanical closing movement of a mechanical key with the identification element, which is reflected in a very intuitive handling of the identification element. It is also conceivable, for additional safety, e.g. a dial, which is arranged around the opening on the identification console. If the identification element is inserted into the opening of the identification console and recognized as correct, a number lights up on the dial. By turning the identification element different numbers are selected depending on the rotation. Thus, for example, a numerical code can be implemented as an additional security element, which must be entered after introduction of the identification element.
- the reading unit In order to determine whether an identification element is introduced, the reading unit is preceded by a sensor unit. As soon as the sensor unit registers that the identification element is being introduced, the reading unit is switched on and the identification element can be scanned. This saves a constant standby operation of the entire reading unit, so that only the sensor unit must be constantly supplied with power.
- a sensor unit can manage with a current of, for example, 0.5 ⁇ .
- the identification element is produced by means of a special method.
- the coding that can be generated by means of a random generator and optionally the at least one known coding is impressed onto the identification element during an embossing process with the aid of an embossing machine.
- the identification element processed until, for example, the entire coding is embossed with all its coding elements of a random plane.
- the position of the embossing or whether at a certain position at all an embossing should take place as a random plane, determined and varied by means of the random number generator.
- the sequence of impressions should be mentioned as a further random level, ie which position is marked first or next.
- the identification element is further processed after the embossing process so that the embossed coding for a human is not perceptible without further aids. This material is removed until the impressions are neither visible nor palpable.
- Fig. 2 shows the identification element according to the invention according to Figure 1 in another
- FIG. 3 shows a three-dimensional view of the housing for an identification console
- 6a is a side view of the identification element with frozen mechanical stresses and signature
- 6b shows a section through the identification element with frozen mechanical stresses after stamping processes A, B and C
- FIGS. 1 and 2 show an identification element 10 with at least one signature 100 according to FIG. 6a, which comprises at least one coding which can be generated by means of a random generator and / or at least one known coding which is formed by frozen mechanical stresses 20 according to FIGS. 5a-5c and comprises at least one coding element.
- the coding generated advantageously by means of the random number generator is very difficult to copy and with a high degree of technical complexity, since the number of different coding possibilities in the range of several hundred billion possibilities is quantified.
- the at least one coding which can be generated by means of a random generator can be combined together with a known coding so that step-by-step coding or decoding is made possible. It is also conceivable to use a completely generated by means of a random generator coding.
- the identification element 10 consists in this embodiment essentially of a cylindrical metal body 22, preferably made of stainless steel, which has the shape of a rod, in particular a round rod with a length of for example 50 mm and in addition a length of 25 mm for a handle portion, and a diameter of 8 mm.
- the identification element 10 preferably has a hole 26 for a key ring 28 for easy handling on a conventional keychain.
- the identification element 10 can also have other geometric shapes and dimensions.
- the at least one encoding that can be generated by means of a random generator and / or the at least one known coding comprises a plurality of coding elements.
- the signature 100 is preferably an electromagnetically effective signature 100.
- the signature 100 corresponds to the output value of an amplitude 102 from a reading unit 32.
- the electromagnetic signature 100 can be scanned without contact.
- the random-generable coding formed by frozen mechanical stresses 20 has at least one random plane, which in the exemplary embodiment is given by the local position of the frozen mechanical stresses 20. For example, at a defined local position there is a frozen mechanical tension 20, whereas at a different position there is no frozen mechanical tension 20.
- At least one further random plane is superimposed on at least one random plane.
- This is the case, for example, in the variation of the depth of the frozen mechanical stress 20.
- the variation of the order in which the mechanical stresses 20 are applied to their local position is also conceivable and, depending on the sequence, leads to possibly different signatures 100 due to the solidification occurring when the coding is introduced.
- the identification element 10 has, according to FIG. 2, an encoding area 12 by at least partially encoding elements of the coding being arranged.
- the coding Area 12 has an adjacent or integrated signal zone 18, which is recognizable by means of a reading unit 32 as the end of the coding area 12.
- the entire coding is imperceptible to a human being without further aids, in particular neither visible nor palpable.
- the identification element 10 is not to be regarded or felt, whether it contains a coding and what kind of a possible coding is procured.
- the identification element 10 is part of an identification system 30 together with an identification console 40.
- the identification console 40 has a housing 44 and an opening 42 on one side and connection contacts 46 on the other side according to FIG. 4.
- the opening 42 has a slightly larger diameter than the identification element, for example 8, 1 to 8.2 mm.
- the housing 44 is preferably made of plastic or metal and has a tube 48, for example of Teflon or ceramic, inside as shown in FIG. 4.
- the tube 48 has a slightly larger inner diameter than the identification element 10, e.g. 8, 1 to 8,2mm.
- the electronics for scanning the signature 100 of the identification element 10 is located inside the housing 44 and, according to FIG.
- the 4 a has a reading unit 32 completely extending around the tube 48, and preferably a decoding unit 34.
- the decoding unit 34 can in principle also be arranged at a different location, in particular also outside the identification console 40. Also located in the interior of the housing 44 after the opening 42, a sensor unit 36. If the identification element 10 is brought into the identification console 40, the signature 100 is completely read out during insertion of the identification element 10 of the reading unit 32 and then from the decoding 34 decoded.
- the reading unit 32 which extends completely around the tube 48, is likewise located in the interior of the housing 44.
- the signature 100 is only read as soon as the identification element 10 has been completely inserted into the identification console 40 and subsequently decoded. It is also conceivable that the reading unit 32 does not extend completely around the tube 48 and thereby the identification element 10 has to perform at least one rotation in order to be completely read out.
- the reading unit 32 is embodied in the exemplary embodiment as a non-contact reading unit 32. By means of the reading unit 32, the at least one random level having signature 100 of the identification element 10 is read and a contained coding transmitted to the decoding unit 34.
- the invention is based on the fact that frozen mechanical stresses, which form the coding, lead to a changed signal of the energy exchange, in particular in the case of a magnetic field.
- This change in the signal can be measured, for example, by evaluating the re-magnetization losses.
- the reading unit 32 operates on an electromagnetic basis.
- the identification console 40 is adapted to the shape of the identification element 10 in a further preferred embodiment. According to FIG. 3, the identification console 40 has an elongated shape and an opening 42. Due to the advantageous adaptation of the identification console 40 to the shape of the identification element 10, geometrically other identification elements 10 can not be used with the identification console 40 due to their inappropriate shape.
- the identification element 10 is preferably detectable in different positions and / or orientations relative to the reading unit 32 by the reading unit 32. Furthermore, a detection is independent of the starting position in which the identification element 10 has been introduced into the identification console 40. For this purpose, position information is preferably introduced into the signal zone 18 in order to detect the position of the identification element 10.
- the signature 100 of the identification element 10 can be detected with the reading unit 32, it is also possible to record a sequence of different positions, movements and / or orientations of the identification element 10 relative to the reading unit with the reading unit 32.
- the identification element 10 can initiate an opening / closing mechanism by rotation, such as a mechanical key. It is also conceivable as an additional security level that the opening / closing mechanism is set in motion only by the execution of a specific sequence of movements with the identification element 10, similar to, for example, a combination lock on a vault.
- the reading unit 32 is preferably preceded by a sensor unit 36.
- the sensor unit 36 may be, for example, an inductive, capacitive or optically operating sensor unit 36. Only when a signal of the sensor unit 36 or as soon as the sensor unit 36 detects the insertion of the identification element 10, the reading unit 32 is activated. As a result, a permanent power supply to the reading unit 32 is not required.
- the production of the identification element 10 is shown in FIGS. 5a-5c.
- the identification element 10 has a metal body 22, preferably an elongated rod or rod, from which is assumed. In principle, however, any other form of identification element 10 is also conceivable.
- the encoding which can be generated by means of a random generator and comprises at least one random plane, is impressed on the metal element 22 having identification element 10 during an embossing process 52 according to FIG. 5b within the coding region 12 by means of an embossing machine 50.
- the embossing forms frozen mechanical stresses 20 on the identification element 10 to produce the random plane.
- the embossing process 52 is repeated until the entire coding is impressed.
- the effect of embossing 52 on signature 100 is shown in Figures 6a and 6c as a plot of amplitude 102 versus location 104, e.g. shown in the longitudinal direction of a rod-shaped identification element 10 in each case arbitrary units. According to FIG.
- the identification element 10 has mechanical stresses frozen by at least one embossing process 52, resulting in a corresponding signature 100. Depending on the location 104, a certain amplitude 102 results.
- FIG. 6b shows the frozen mechanical stresses 20 of the identification element 10 after several embossing processes 52A, 52B and 52C.
- the corresponding signatures 100 are after the respective embossing processes 52A , 52 B and 52 C are shown. It is possible that a solidified by a first embossing process area after the second embossing process 52 B has a different nature than after the first embossing process 52 A.
- the first embossing process affects the material properties to affect the result of the second embossment, resulting in a different result than a non-pretreated material.
- the signature 100 changes, for example, after each embossing process 52.
- FIGS. 7a and 7b It is also conceivable in a further exemplary embodiment according to FIGS. 7a and 7b that, for example, impressed on one side of a wandformigen identification element 10 a known coding and on, for example, three other pages of FIG. 7a to the rod-shaped identification element 10 by means of a random generator generated codings as random planes are.
- the signature 100 A resulting from the known coding serves as a system clock shown in dashed line according to FIG. 7 b, which specifies at which sampling points, eg at which location 104 or above a certain amplitude, the other signatures 100 B, 100 C, and 100 D, which result from the codings produced by means of a random generator can be read out.
- the sample points shown here, symbolized by the chelten lines starting from the system clock, are only to be seen as an example, in practice also substantially more sampling points can be used.
- the identification element 10 is processed further such that the embossed coding can not be perceived by a human without further aids, in particular neither is visible nor palpable.
- the round rod is turned off to a smaller diameter, which is illustrated by the dashed line in Fig. 5c.
