Description

The invention relates to a sensor, measuring and evaluation module for checking the authenticity of a product, a real product having a predetermined secret feature that can be excited by means of electromagnetic radiation, the sensor, measuring and evaluation module checking the product for the presence and checks and evaluates the properties of the secret feature. Such a sensor, measurement and evaluation module is also referred to as an embedded genuineness sensor module (eGSM). The invention also relates to a method for determining the authenticity of a product with the sensor, measurement and evaluation module.

The invention relates to the protection of products and systems made up of several interacting products, for example for the in-situ authenticity check of consumables in a mobile device.

Nowadays, hand-held devices are used to secure and authenticate goods, labels, customs stamps, passports and the like, which either test a certain material property and display the test result to the user immediately, or the authenticity of a device via cryptographic testing with or without a server / internet connection Confirm product.

Authenticity checks that are carried out with a mobile phone are either based on a code or chip with signature or database verification, or only use simpler verification methods (e.g. using a camera and flash) because the mobile phone does not have any special sensors for authenticity checks .

The risk of product counterfeiting will continue to increase in the future due to advancing globalization and digitization, and consumers / patients will increasingly be confronted with the question of the authenticity of the products / drugs used. For reasons of product liability and reputation, manufacturers of branded goods must ensure the authenticity of the products they sell. This challenge cannot be solved or only inadequately with digital methods alone.

The disadvantage of the devices and methods known from the prior art is that devices for the detection of special feature substances are rather large and expensive, or space is required on the product for a visually visible code or for a chip. The in-situ authentication of small consumables, such as tobacco sticks (also called HEETS®) for tobacco heaters or insulin ampoules, or authentication with a mobile phone, integrated in a hand-held device, is not possible with the technology known from the prior art.

The invention is therefore based on the object of developing a generic sensor, measuring and evaluation module in such a way that the disadvantages of the prior art are eliminated.

This object is achieved by the features of the independent claims. Developments of the invention are the subject of the dependent claims.

According to the invention, the sensor, measurement and evaluation module can be integrated or embedded in a mobile device, the sensor, measurement and evaluation module consisting of an optics module for recording the properties of the secret feature and for providing analog measurement signals of the secret feature and consists of an electronics module, whereby the electronics module consists of an analog module for amplification and digital-analog or analog-digital conversion of the measuring signals of the optics module, a digital module for evaluating the analog measuring signals digital measurement signals of the secret feature and decision about its authenticity, as well as a Interface module for passing on the result of the authenticity check to the mobile device, the mobile device displaying the result of the authenticity check and / or performing an action dependent on the authenticity, with the product being introduced into the mobile device or brought into the vicinity of the mobile device, see above that the secret feature can be detected by the optics module.

Alternatively, the sensor, measurement and evaluation module can be integrated or embedded in a mobile device and sends the results of the authenticity check to the mobile device via a likewise integrated interface module, the mobile device displaying the result of the authenticity check and / or one of the authenticity performs dependent action, the product being introduced into the mobile device or brought into the vicinity of the mobile device so that the secret feature can be detected by the sensor, measurement and evaluation module. Here, the sensor, measurement and evaluation module can consist of an optics module for recording the properties of the secret feature and for providing analog measurement signals of the secret feature and consist of an electronics module, the electronics module being an analog module for amplification and digital-to-analogue or analog-to-digital conversion of the measurement signals of the optics module, a digital module for evaluating the digital measurement signals of the secret feature resulting from the analogue measurement signals and a decision on the authenticity of the product and an interface module to pass on the result of the authenticity check to the mobile device.

Several or all of the described modules of the sensor, measurement and evaluation module are preferably integrated as a microsystem. Most or all of the units and / or modules, especially the analog and digital circuits, can be combined in a mixed-signal ASIC, i.e. in an application-specific integrated circuit for mixed analog and digital electronic components.

A predetermined secret feature is a feature that is not known to a user. In this case, the user is usually neither aware of the presence of the secret feature on or in the product, nor the composition and properties of the secret feature. For example, a predetermined secret feature is a specific combination of rare earths which are incorporated into the material of the product or applied to the surface of the product and which can be read using infrared radiation. Alternatively, a predetermined secret feature can be a luminescent substance which can be excited with electromagnetic radiation of a specific wavelength and which, after being excited with this electromagnetic radiation, emits electromagnetic radiation of a specific wavelength that is different from the specific wavelength of the exciting electromagnetic radiation. Alternatively, a predetermined secret feature can also be the surface properties of the product in a certain sub-area of the surface of the product or of the entire surface of the product. Another predetermined secret feature would be, for example, information hidden in a hologram, which can only be read at a certain viewing angle, when excited with coherent radiation or when excited with electromagnetic radiation of a certain wavelength.

The invention thus has the particular advantage of offering an authenticity sensor system that is small enough to be integrated into a handheld device, such as a tobacco heater, an insulin syringe or a mobile phone, and the result of the test on the handheld device or protected against manipulation to report to another, higher-level system.

In addition to its function as, for example, a tobacco heater, insulin syringe, pen or mobile phone, the mobile device particularly preferably has the additional function, which is independent of this function, as a sensor, measuring and evaluation module. In addition to the additionally integrated authentication, the hand-held device has one or more main functions, such as Phoning, writing, scanning passports.

The entire sensor, measurement and evaluation module is particularly preferably located in a volume with a length, width and height of about 3 mm x 3 mm x 3 mm to about 10 mm x 10 mm x 10 mm in order to integrate the authenticity detection in to enable a mobile or handheld device. This volume corresponds approximately to the volume of a camera of a cell phone known from the prior art.

The connection for a power supply, a serial interface (e.g. USB, i ² c, SPI, RS232) and / or a wireless / radio interface (e.g. NFC, RFID, Bluetooth, WLAN) are particularly preferred as interfaces to the mobile or handheld device. , as well as an optical interface for authentication. The module is protected against external attacks by drilling protection and deletion of programs and data when intrusion is detected.

According to a preferred embodiment, it is provided that for secure communication with the mobile or handheld device or with the higher-level system, an embedded secure element (eSE), TPM, TEE (Trusted Execution Environment, e.g. arm trust zone, or the like) Module is integrated so that the eGSM can authenticate itself to the outside using challenge-response processes known from the prior art.

The module can be integrated directly into a mobile or handheld device, also known as a host, and checks, for example, the authenticity of consumables. If the authenticity check is positive, the control of the hand-held device is informed of the successful check and can continue with normal operation, for example heating tobacco, and / or inform the user about the authenticity of the material. In the negative case, further operation can be refused and / or the user can be informed about the lack of authenticity of the consumable material. An optional authenticated / encrypted communication between the security module and the host system prevents manipulation of the release / display.

According to a preferred embodiment, the optics module consists of at least one emitter for electromagnetic radiation of one or more specific wavelength ranges, for example an LED, and at least one detector for electromagnetic radiation, for example a photodiode. Filters can be assigned to the emitter and detector. Between the emitter, detector and the measuring surface of the eGSM, other means influencing the beam path can be placed. for example lenses, light guides, etc. The optics module can either be attached directly to the main body of the eGSM or connected via a flexible cable if the measuring surface has to be guided to a particularly small location. Alternatively, the measuring surface can be laid to the measuring object via a single or multi-channel light guide.

The electronic module of the eGSM consists of an analog module, digital module, interface module and optionally a protection module with protection logic that protects the eGSM from external attacks and espionage. All parts of the electronics module are preferably integrated in a mixed-signal ASIC to save space.

According to a preferred embodiment, the analog module consists of at least one transimpendance amplifier with very high dynamics in order to be able to measure small currents with high resolution, an amplifier with variable gain, at least one analog / digital converter and at least one digital / analog converter. Transimpedance converters, amplifiers and A / D / D / A converters can each also be merged for one channel. The analog part has at least one such channel, preferably several channels, optionally with a multiplexer.

According to a preferred embodiment, the digital module consists of at least one processor (MCU) with at least one core, volatile and / or non-volatile memory units (RAM, SRAM, Flash, etc.), an embedded security element (embedded secure element - eSE) , which can also be integrated into the processor, as is proposed, for example, in the arm M23 or M33 architecture, and optionally a protection logic for the detection of attacks.

An embedded security element (eSE) is a chip that is protected against manipulation and can be embedded in the eGSM. Data and key material are saved here so that they are protected from access by third parties and data is only given to authorized persons.

According to a preferred embodiment, the interface module consists of the connection for a power supply and various interfaces for data exchange with the host system and optionally with the cloud. At least one data interface with cable (for example USB, SPI, I ² C, RS232) or a radio interface (for example NFC, RFID, WiFi, Bluetooth, LoRaWAN) is preferably provided. The cable connection can be made via a flexible cable and circuit board connector, as in a mobile phone.

Due to the small design, the low power consumption and especially the flexible positioning of the measuring surface, the eGSM can be integrated into any handheld device for authentication purposes.

The eGSM according to the invention can be produced in large numbers very inexpensively using standard semiconductor processes.

The direct hedging of consumables helps manufacturers of branded goods to protect their high investment costs for technology, and also to guarantee customers that they are only using original material. This is particularly essential for drugs or other safety or health-related products. A hand-held device with an integrated eGSM can also be used to check banknotes and security documents.

Due to the easy integration option in host devices with a standardized host interface, a separate form factor does not have to be developed for the eGSM for each application. The user software is preferably developed by users themselves.

• Durch die Integration des eGSM in einen Tabakerhitzer bzw. Inhalator für eZigaretten und eines von dem eGSM erfassbaren geheimen Merkmals in die Tabaksticks bzw. HEETs kann die ausschließliche Verwendung von originalen Tabaksticks sichergestellt werden. Dies schützt gleichermaßen den Hersteller der Markenartikel wie den Anwender. Es gibt hierbei mehrere Möglichkeiten mit dem Einlegen von nicht originalem Verbrauchsmaterial ohne geheimen Merkmal umzugehen. So kann entweder der Anwender nur über die Verwendung von nicht originalem Verbrauchsmaterial informiert werden, die „Rauch“-Funktion aber trotzdem durchgeführt werden. Alternativ oder zusätzlich kann die Benutzung des nicht originalen Verbrauchsmaterials unterbunden werden und/oder eine entsprechende Information in die Cloud gesendet werden.

Some forms of application of the invention are described below:

• By integrating the eGSM in a tobacco heater or inhaler for e-cigarettes and a secret feature that can be recorded by the eGSM in the tobacco sticks or HEETs, the exclusive use of original tobacco sticks can be ensured. This protects the manufacturer of the branded goods as well as the user. There are several ways to deal with the insertion of non-original consumables without a secret feature. Either the user can only be informed about the use of non-original consumables, but the "smoke" function can still be carried out. Alternatively or additionally, the use of the non-original consumables can be prevented and / or corresponding information can be sent to the cloud.

By integrating the eGSM in drug dosing units such as insulin pens and the secret feature in the associated insulin ampoules, the exclusive use of original material can be ensured. This protects the patient from dangerous counterfeits.

By integrating the eGSM in passport scanners, the feature check of the secret feature integrated in the passport paper can be carried out can be integrated into stationary as well as mobile devices.

By integrating the eGSM into BOS radios, such as police radios, public officials are able to check customs stamps, passports and other secure documents for authenticity while on the move.

By integrating the eGSM directly into mobile phones or other mobile devices, or by integrating it into a USB-C, mini-USB or Lightning add-on module that can be plugged into a mobile phone or other mobile device, the authentication of secret features can be relocated to practically any mobile device. Customers can elegantly check the authenticity of branded articles ordered on the Internet, for example batteries, accessories, devices, textiles, shoes, etc. A system with a secret feature is therefore immensely more interesting for branded goods, because the possibilities for checking are increased. Such a mobile device could have the design of a ballpoint pen, which is a ballpoint pen on the one hand and an authentication device on the other. The device can be equipped with a small display or just two LEDs and two buttons. It could also be used to check the authenticity of banknotes.

The invention further relates to a method for determining the authenticity of a product with an aforementioned sensor, measurement and evaluation module or eGSM according to the invention with the following steps:

1. a) by inserting the product into the mobile device or bringing the product closer to the mobile device and / or pressing a button and / or another action by the user on the mobile device, the determination of authenticity is started,
2. b) the mobile device sends a command to the sensor, measurement and evaluation module via the interface module to begin determining the authenticity,

5. e) the mobile device receives the result of the decision and, depending on the result of the decision, displays a corresponding message for the user and / or, in the case of a real or original product, enables the use of the product in the mobile device.

The other action of the user on the mobile device mentioned in step a) can be, for example, touching or swiping a certain field on a display of a smartphone with a finger, a voice command or a text message.

According to a preferred embodiment, in step a) the product, for example a tobacco stick, is introduced into the mobile device, for example a tobacco heater of an e-cigarette, and in step e) the use of the product in the mobile device is enabled if the product is recognized as authentic. If the authenticity check of the product is negative, however, the use of the product in the mobile device can be blocked and / or a warning can be displayed or issued by the mobile device.

According to a preferred embodiment, authentication takes place between the mobile device and the sensor, measurement and evaluation module at least when the mobile device is switched on.

According to a preferred embodiment, the communication between the mobile device and the sensor, measurement and evaluation module is encrypted and / or secured against falsification by means of digital signatures.

In connection with the authenticity check according to the invention, it is important that the check of the conformity of the measurement result with the specified measurement result for a real or original product takes place exclusively in the secure environment of the eGSM. No information about the evaluation may reach the unsecured area of the host, so only the result of the check is transmitted to it. This prevents authenticity check details from being easily spied on.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the specified combinations but also in other combinations without departing from the scope of the present invention, insofar as this is covered by the scope of protection of the claims.

• 2 an authenticity check according to the invention,
• 3 an inventive sequence of an authenticity check of consumables and subsequent approval of use,
• 4th an inventive sequence of authentication between host and eGSM,
• 5 an inventive sequence of authentication between eGSM / host and cloud.

1 schematically shows a structure of a sensor, measurement and evaluation module eGSM according to the invention. The eGSM consists of an optics module (optics) and an electronics module (electronics).

The optics module has at least one light-emitting diode LED, which applies electromagnetic radiation of one or more specific wavelength ranges to the secret feature of a product (not shown) via an optional filter F and an optional lens L. At least part of the electromagnetic radiation reflected back by the secret feature is measured by at least one photodiode PD, a filter F and a lens L also being able to be located in front of the at least one photodiode PD.

The at least one light diode LD is controlled and the measurement signals from the at least one photodiode PD are received via the analog module (analog) of the electronics module, which for this purpose has at least one transimpendance amplifier Z, V of very high dynamics in order to be able to measure small currents with high resolution , a variable gain amplifier, at least one analog / digital converter ADC and at least one digital / analog converter DAC. The optics module and the electronics module can be formed by a single module so that both modules are directly connected to one another. Alternatively, the optics module and the electronics module can be formed by separate modules and connected to one another via cables.

The analog module communicates with a digital module (digital) of the eGSM, which consists of an MCU, a memory, a protection logic and an eSE. The task of the protection logic is to ward off external attacks on the eGSM or to destroy the eGSM before a successful attack.

The digital module in turn communicates with an interface module (interface) of the eGSM, which is the connection for a voltage supply (VC) for the eGSM with, for example, 5 V or 3.3 V and a wired (wired) and / or wireless (wireless ) There is a communication facility with the host.

The host is, for example, a mobile phone, a pen or a tobacco heater of an e-cigarette and displays the result of the measurement of the eGSM. In addition, the host can communicate with a cloud and report the test result to the cloud.

2 to 5 show various options for activity diagrams for communication between the host or handheld or mobile device and the eGSM integrated in the host.

2 shows schematically a general sequence of an authenticity check. An operator starts by pressing a key 1 the authenticity check 2 . The host recognizes in step 3 that the authentication should be started and gives in step 4th the command to the eGSM, with step 5 to begin the authentication process. The eGSM stimulates in step 6th for example, with an LED the secret feature in the product to be tested and measures in step 7th for example with a photodiode the answer of the secret feature. In step 8th the measurement signal is evaluated and in step 9 the eGSM sends the result of the authenticity check to the host. The host takes in step 10 counteracts the result of the authenticity check and decides how the further program sequence is continued depending on the result of the authenticity check, with a green LED in the case of authenticity “true” 11 and in the event that the "false" feature is missing, a red LED 12 lights up on the host.

The result of the authenticity check is preferably encrypted by the eGSM and / or transmitted to the host in a secure manner by means of a signature / hash value and thus secured against manipulation or falsification. The embedded secure element eSE plays the main role.

3 shows schematically a sequence of the authenticity check of consumables and subsequent approval of use. An operator or user leads in step 2 ' a product, for example a tobacco stick, into a host or mobile device, for example a tobacco heater of an e-cigarette, and starts by pressing a button 1 or the authenticity check is carried out by inserting the product. The host recognizes in step 3 ' that the authentication and thus the use of the e-cigarette has been started and gives in step 4th the signal to the eGSM, with step 5 to begin the authentication process. The eGSM stimulates in step 6 ' for example with an LED the secret feature in the tobacco stick and measures in step 7th for example with a photodiode the answer of the secret feature. In step 8th the measurement signal is evaluated and in step 9 the eGSM sends the test result to the host. The host decides in step 10 depending on whether a real or original product was recognized by the eGSM, with a red LED in the event of no recognition “false” 12 lights up on the host. A green LED lights up if the detection is "true" 11 on the host and is in step 13 approved the use of the tobacco stick in the tobacco heater.

The eGSM is used in a hand-held device to check the authenticity of consumables and, if authenticity is recognized, to approve the use of the device. Depending on the intended use of the device, if the authenticity check is negative, a repetition of the check is initiated and then the user is informed and further use is prevented (for example for medication) or allowed or restricted.

4th shows schematically a process of mutual authentication between host and eGSM in order to prevent manipulation by the user or third parties.

An operator or user switches here by pressing a key 1 in step 2 " the host, followed by step 14th the host and in step 14 ' start up or boot the eGSM.

The host gives in step 15th the signal to the eGSM, with step 15 ' to begin with authentication. The eGSM divides in step 16 the eSE to start the authentication with the host, whatever it is in step 17 ' does and the host in step 17th enters into the mutual challenge / response authentication process and brings it to a conclusion. In step 18th The eGSM optionally also notifies the host of the result of the authentication from his point of view. In step 19th the host decides and in parallel in step 19 ' the eGSM as to whether the authentication was successful in each case, with the host enabling operation if the match is “true”, step 20th , as well as the eGSM, step 20 ' .

In the event of failed authentication, the host gives "false" with step 21st an error message and exits the eGSM in step 22nd the company.

The authenticity check or authentication is preferably carried out by an eSE integrated into the eGSM. Depending on the security requirements, the host system should also have an eSE, a secure processor (core), a trust zone or WhiteBox security.

In many cases, authentication to a server system in the cloud can also be useful. 5 shows schematically the corresponding process of authentication between host and cloud, which essentially consists of the process 4th corresponds. The only difference is that the host is in step 23 establishes a "tunnel" to a cloud with a TIM server (TIM means Trusted Identity Manager, a server system that is responsible for the administration of the (device) identities and the tasks mentioned above), so that the eGSM in step 17 ' communicates directly with the cloud and in step 17 " performs the authentication with the corresponding server.

The authentication is preferably carried out by an eSE integrated into the eGSM.

The authentication to a cloud can also be used for secure data transfer from or to the handheld device or eGSM, secure software updates, key and rights management or pay-per-use applications.
