Description

[0001] Anti-theft device, in particular for securing a mobile device

[0002] The invention relates to a novel anti-theft device for protecting a mobile device against theft and loss.

[0003] Due to their closed, flat outer shell, mobile phones and most mobile devices cannot be easily secured by inserting, hanging or installing locks, chains or similar devices, as is the case with bicycles or cars, for example.

[0004] Numerous apps and hardware components offer a variety of alternative security options to solve this technical problem. However, as the low sales figures and low level of awareness show, state-of-the-art anti-theft devices, despite their low cost, only convince a very small number of people. Although the need for a simple and therefore self-evident security option is strongly felt by almost all mobile device users, and the necessity for this has actually grown with the increasing prevalence and often quite high value of mobile devices, and the increasingly technological world suggests otherwise, the majority of mobile devices are still lying around completely unsecured and within easy reach of any thief, for example in changing rooms, on the beach, in youth hostels, in offices or in hospital rooms.

[0005] There are apps that trigger alarm actions as soon as the cell phone is moved. Such apps have the disadvantage that an alarm is also triggered if the cell phone is accidentally moved by the owner or another person, or by the movement of a train, for example. The owner themselves must deactivate the alarm before moving the cell phone, and in many situations this is not possible or very impractical. There are apps that trigger alarm actions as soon as the cell phone is disconnected from a data and / or data charging cable. Such apps have the disadvantage that protection against theft is only possible where the user has access to a power outlet or PC, which is not the case in most places where you would want to secure a mobile device.

[0006] Another option is to use apps that detect whether someone is trying to unlock the device. If the attempt is unsuccessful, the alarm is triggered. Such approaches have the disadvantage that an alarm is triggered even if the owner fails. Furthermore, the phone can be stolen without triggering an alarm. Whether the alarm is triggered at a later time depends on many factors, such as the thief's technical skills.

[0007] There are many apps that are only deployed after a theft has occurred and been detected. They offer the owner various options. Common options include locating the stolen phone, accessing or remotely deleting data, triggering an alarm on the phone, etc. Since these apps do not provide anti-theft protection but are only deployed after the theft, this is a completely different approach.

[0008] State-of-the-art anti-theft devices that only work with additional hardware are also not widely used because they often limit the spontaneous use of the mobile device, are not easy to operate and / or cannot be used in a sufficient number of situations.

[0009] A variant of an anti-theft device with additional hardware built into and on the device, which can only be used with this type of anti-theft device, is described, for example, in US 2018 / 0285285 A1. In general, there is potential for improvement with regard to theft protection of mobile devices such as mobile phones, e-books, or laptops.

[0010] With the increasing standardization of data connection charging sockets and charging outlets (e.g. USB-C type), the possibility should be used to use these ports additionally for coupling a standardized anti-theft device.

[0011] Therefore, the object of the present invention is to at least partially solve the problems described with reference to the prior art. This object is achieved by the invention according to the features of the independent patent claims. Further advantageous embodiments are specified in the dependent claims as well as in the description and, in particular, in the description of the figures. It should be noted that the person skilled in the art can combine the individual features in a technologically expedient manner and thus arrive at further embodiments of the invention.

[0012] The invention relates to an anti-theft device for use with a mobile device, wherein the anti-theft device has a feedthrough and a plug for plugging into a connection of the mobile device, wherein at least one continuous conductive element enclosing the feedthrough is arranged in the entire anti-theft device, which is connected to the plug in such a way that software operated on the mobile device can register any change in the electrical properties of the conductive element, wherein both the plugging in and the unplugging of the plug and also the severing of the conductive element each represent a change in the electrical properties and thus a registerable change, whereby the anti-theft device provides an electronically secured feedthrough connected to the mobile device, which enables the mobile device to be fastened,whereby at least the mobile device can be protected from theft. Instead of the bushing or in addition, the anti-theft device can have a base that allows for permanent attachment of the anti-theft device, e.g., to furniture or walls. The at least one line element must be installed in the base in such a way that damage to the base also leads to damage to the line element.

[0013] It is advantageous if the anti-theft device is a cable with a plug connected thereto for insertion into a connection of the mobile device and the anti-theft device further comprises a feedthrough through which the plug can be passed in order to form a cable loop, wherein the feedthrough is designed in such a way that a mobile device connected to the plug prevents the cable loop from being opened, wherein the at least one continuous line element must completely enclose the feedthrough and thus the cable loop.

[0014] The term "mobile device" refers in particular to mobile phones and cell phones, but also to laptops, tablets, notebooks, iPads, MP3 players, portable speakers, photo and video cameras, etc. This particularly includes all mobile devices that have at least one data connection, charging socket or charging port, which forms a connection and which allows the owner to enter a code on the hardware side, e.g., by pressing key combinations, entering a number combination, or drawing patterns on a display, fingerprint recognition, facial recognition, etc.

[0015] This includes all mobile devices with the described, usual and largely standardized features, without changing, expanding or specially equipping the devices themselves in any way, either visually or in terms of hardware.

[0016] Preferably, the input option(s) are already present on the mobile device, as they are typically required, for example, to lock / unlock the device and do not need to be specifically installed or attached to lock / unlock an anti-theft device. Furthermore, such input options can often also be implemented using the software development functionality provided on common mobile devices.

[0017] The term “connection” or connection socket always refers to the necessary data connection charging sockets and charging outlets installed on every device.

[0018] The term “conducting element” refers to electrical wires that can be installed in a cable, particularly preferably electrically conductive wires.

[0019] The described cable loop can be placed around a fixed structural element or attachment point to secure the mobile device connected to the anti-theft device or plug. Attachment points on all fixed structural elements that cannot be moved or are difficult to move, such as stair railings, hospital beds, sun loungers, etc., are particularly useful.

[0020] The cable loop cannot be broken without breaking the connection between the plug and the connector or damaging the anti-theft device, i.e. without a change in the electrical properties of at least one cable element that can be registered by the software and which in turn would trigger an alarm response on the mobile device.

[0021] The most important function of the software running on the mobile device to monitor the anti-theft device connected to the port is to monitor the electrical properties, i.e., whether the anti-theft device's plug is plugged in or unplugged, and whether the anti-theft device is damaged, severed, or otherwise tampered with. Once the anti-theft device's plug is plugged in, the software's monitoring function can be activated. To then unplug the plug without triggering an alarm, an unlocking measure is required—for example, entering a code or using facial recognition. Any unplugging or damage to the anti-theft device, resulting in a change in the electrical properties of at least one line element, will inevitably trigger the alarm if the monitoring function is activated.

[0022] It is also advantageous if at least one line element extends through the cable, enclosing the feedthrough, so that when the cable is severed to release the cable loop without unplugging the plug from the connection, an impairment of the line element occurs, which can be detected by software running on the mobile device.

[0023] A line element is particularly designed as a wire. Preferably, a line element extends through the entire anti-theft device, so that regardless of where damage to the anti-theft device occurs, at least one line element is affected.

[0024] Furthermore, it is advantageous if the plug of the anti-theft device and the connection of the mobile device each have at least two contacts which are connected to one another by the at least one line element, so that the software operated on the mobile device can monitor an electrical property of the line element.

[0025] Contacts are in particular contact pins or contact surfaces within the

[0026] Plug, which interact with corresponding contacts in the connector to create an electrical connection between the anti-theft device and the mobile device.

[0027] It is also advantageous if, in the anti-theft device, at least two line elements are separated from one another by at least one dielectric material, wherein the dielectric material and the at least two line elements form a circuit whose electrical properties can be monitored by the software operated on the mobile device, wherein a severing of the cable causes a change in the electrical properties that can be registered by the software.

[0028] Preferably, the electrical conducting elements and the dielectric material form an electrical circuit whose electrical properties can be monitored using the software on the mobile device. In particular, this circuit has capacitive properties and thus acts at least partially as a capacitor. Preferably, the conducting elements are arranged such that manipulation of the anti-theft device results in a change in this electrical circuit, which can be detected by the software running on the mobile device and thus used as a trigger for triggering an alarm.

[0029] It is also advantageous if at least two line elements are arranged in the cable at least partially lying one inside the other, so that an inner line element is surrounded by an outer line element.

[0030] With such an arrangement, the inner conductive element is protected from the outside by the outer conductive element. For someone attempting to tamper with the anti-theft device, it is virtually impossible to reach the inner conductive element without first compromising the outer conductive element. It has been found that nested conductors provide very good protection against tampering with the anti-theft device, which cannot be detected by the software running on the mobile device. Most preferably, the dielectric material is arranged between the inner conductive element and the outer conductive element. This allows a capacitive circuit to be formed.

[0031] Furthermore, it is advantageous if at least two line elements are arranged in the cable, at least in sections, twisted together.

[0032] Furthermore, it is advantageous if the at least one line element is arranged in the cable in a twisted manner, at least in sections. If the line element only runs parallel back and forth, the undesirable enlargement of the feedthrough is possible. If the at least one line element is twisted at least in front of and behind the feedthrough, enlarging the feedthrough without damaging the line element becomes virtually impossible.

[0033] In this context, the line elements are particularly preferably embedded in a matrix material, and from the outside, it is preferably not possible to see where or how the line elements are arranged in the cable or in the anti-theft device. This also makes tampering with the anti-theft device more difficult.

[0034] It is also advantageous if the plug is a USB type plug.

[0035] It is particularly advantageous if the connector is a USB-C type connector.

[0036] These are common connector types. With these connectors, the anti-theft device can be used with most mobile devices.

[0037] Since the anti-theft device presented here uses only connectors that are suitable for plugging into a mobile device port (= existing charging / data / charging ports), and commercially available adapters are available for these connectors and ports, virtually any version of the anti-theft device can be used on virtually all mobile devices available on the market. This makes it possible, for example, to provide permanently mounted anti-theft devices that can be used by virtually any device owner if necessary, and anti-theft devices can be loaned out.

[0038] In addition, the use of an existing charging / data / charging port offers the advantage that no additional hardware needs to be installed or retrofitted on and / or in the device to be secured in order to operate the anti-theft device, which always leads to negative optical or physical changes to the device to be secured.

[0039] It is also advantageous if the feedthrough is an eyelet which is firmly connected to the cable.

[0040] Particularly preferably, an eyelet is arranged at one end of the cable to form a cable loop. An eyelet can also be formed in a central area of ​​the cable or directly on the plug, depending on the application for which the respective anti-theft device is intended.

[0041] It is further advantageous if at least one feedthrough is formed by at least a partial splitting of the cable.

[0042] It is particularly advantageous if the anti-theft device has the complete cabling and the two connectors required for operation as a data and / or data charging cable, with at least one of the connectors having a mechanically operated circuit that enables a function change from the anti-theft device to a data and / or data charging cable. It is further advantageous if the at least one connector with the mechanically operated circuit for the function change mechanically prevents this connector from being inserted into a connection when the switch is in the "anti-theft device" position.

[0043] It is particularly advantageous if the anti-theft device has the complete technology for operation as a data storage device or USB stick, wherein the at least one plug has a mechanically operated circuit that enables a change of function from the anti-theft device to the data storage device or USB stick, whereby the data storage device is of course fully retained during operation as an anti-theft device.

[0044] The data storage device described here preferably does not refer to a data storage device that only stores data required to operate the data backup device. Rather, it is intended to be a data storage device that, from the perspective of the mobile device, functions like a drive or USB stick and on which any data can be stored.

[0045] It is further advantageous if the number of installed cable elements and their occupancy by the device allow the anti-theft device to be used as an anti-theft device and / or data cable and / or data charging cable and / or data storage device or USB stick without switching.

[0046] This design variant allows a cable with conductive elements to be used both as an anti-theft device and for charging. In this case, the mobile device can be optionally secured, for example, during the charging process, a time when the device is often not in use.

[0047] It is also advantageous if at least one electronic component is installed in the anti-theft device which clearly identifies the anti-theft device as such for the mobile device, whereby a possible switch to another function also requires a change in the identification (chips for electronic marking).

[0048] The electronic component or marking represents a fixed "type plate" built into at least one of the plugs. This type plate is not required for the operation of the anti-theft device, but rather serves to ensure that the device being secured recognizes the anti-theft device as such when plugged in. This marking is preferably permanently implemented and unchangeable. It is especially preferred that this marking cannot be deleted. If the anti-theft device is plugged into another device, the same markings must be present so that this device can also recognize the anti-theft device.

[0049] It is further advantageous if the anti-theft device has, in addition to the one plug required for connection to a device, another plug and a matching connection socket, wherein only by bringing these together is an interruption in the at least one continuous line element closed and, at the same time, the feedthrough or cable loop required for fastening the anti-theft device closed.

[0050] It is further advantageous if at least one of the plugs of the anti-theft device has a mechanically operated mechanism that allows the plug to be blocked from being unplugged from the device's connection socket. This prevents accidental disconnection and thus accidental alarm triggering, and the anti-theft device can be used to protect against losing or forgetting the device, even without activating the monitoring function on the device. The mechanically operated mechanism described here for blocking the plug from being pulled out does not have to be used to operate the anti-theft device. Such a mechanism has no direct impact on the operation / operability of the core function of the anti-theft device. However, such a mechanism provides an additional convenience feature.

[0051] Preferably, such a mechanically operated mechanism does not require a key or numeric code, but can also be operated “blindly” without any additional tools, e.g. by turning the plug housing or moving a slider.

[0052] Furthermore, it is advantageous if the anti-theft device has a stopper which limits further passage of the anti-theft device through an opening through which the plug can still be guided.

[0053] A stopper, in particular, makes it possible to limit the threading of the anti-theft device. This allows the anti-theft device to be attached to any hole or slot in a structural element through which the plug can pass, but not the stopper. For example, passages that are part of other structural elements can be used between a stopper and the mobile device to also secure them with the anti-theft device and / or to close them. These could be, for example, slider pulls on a backpack zipper.

[0054] This allows the anti-theft device to fulfill multiple tasks simultaneously: The contents of the backpack are protected against theft by the secure closure, the backpack itself is attached to the anti-theft device and thus protected against theft, and the mobile device is simultaneously protected against theft. Many other applications are possible. Furthermore, it is advantageous if the anti-theft device has a base that allows for (permanent) attachment of the anti-theft device to a structural element.

[0055] Many of the design variants described here, alternative mounting options, and feedthrough arrangements enable multifunctional use of the anti-theft device. These represent a significant advantage in the context of anti-theft devices compared to the state of the art, which exclusively describes anti-theft devices that cannot fulfill any other function.

[0056] It is also advantageous if the cable of the anti-theft device can be wound at least partially into the plug housing or an additional housing, or can be wound automatically using a conventional mechanism. This allows the size of the anti-theft device to be reduced when not in use, and an additional housing can also serve as a stopper.

[0057] Also to be described here is software for installation on a mobile device and configured to operate a described anti-theft device, wherein the software is configured to monitor at least one electrical property of the at least one line element, i.e. whether the plug of the anti-theft device is plugged in or unplugged and whether the anti-theft device is damaged, severed or tampered with in any other way. After the plug of the anti-theft device has been plugged in, the monitoring function of the software can be activated. In order to then unplug the plug without triggering an alarm, an unlocking measure is necessary, wherein the measure to be carried out to unlock the device can be, for example, entering a code or using facial recognition and / or entering a code defined solely for terminating the monitoring function.Any unplugging or damage to the anti-theft device resulting in a change in the electrical properties of at least one line element will inevitably trigger the alarm if the monitoring function is activated.

[0058] It should be noted that the particular advantages and design features described in connection with the anti-theft device described above are also applicable and transferable to the software described in more detail below.

[0059] Preferably, the software is available as an app in standard online stores for mobile device apps and can be installed on mobile devices from such online stores. The software can also be provided in any other way, e.g., on a data storage device or pre-installed on a mobile device in its delivery state.

[0060] Preferably, the software is configured to emit an alarm signal and / or a notification when, with the monitoring function switched on, the plug of the anti-theft device is pulled out of the connection of the device and when a change in the monitored electrical properties of a line element of the anti-theft device is registered, wherein a severing of the line element also represents a registerable change.

[0061] Alarm signals can be issued in a variety of ways - for example in the form of sounds, vibrations and / or in the form of messages sent to recipients.

[0062] Preferably, the software allows the monitoring function to be deactivated by unlocking the mobile device as usual. This use of the usual inputs on the mobile device to be secured itself to activate / deactivate the anti-theft device or the monitoring function carried out with the software and the anti-theft device represents a huge advantage over the state of the art. The user does not have to remember an additional numeric code for a combination lock or operate an impractical combination lock, which is time-consuming and not even possible in the dark. No key is used, which in turn must be securely stored by the user while the mobile device is being secured, which is not possible in many applications (e.g., during an examination in a hospital or while the user is asleep).

[0063] Preferably, the software has an unlocking function with which, for example, a PIN can be requested on the mobile device, facial recognition and / or fingerprint recognition can be carried out in order to only deactivate the monitoring function without unlocking the entire device.

[0064] Furthermore, the software is preferably configured to monitor an electrical property of the conducting element and to detect a change in the electrical property that may indicate manipulation of the anti-theft device.

[0065] Furthermore, the software is preferably configured to activate a self-protection function of the mobile device when a change in the electrical property is detected which is attributable to manipulation of the anti-theft device.

[0066] Activating a self-protection function is not necessary for the operation of the anti-theft device and has nothing to do with the storage or processing of data. This function is intended to describe emergency scenarios to the device. The device's own processors are intended to be controlled in such a way that they prevent damage to the device, for example, by deactivating components and / or switching. This damage would otherwise occur, for example, due to incorrect pin assignments or a mismatch between the plugged-in hardware and the current expectations / capabilities of the device.

[0067] Example 1: If the software for operating the anti-theft device is not activated on the device and the device is therefore not prepared for the "short circuit" of two contacts, plugging in the anti-theft device must not cause damage to the device.

[0068] Example 2: If the anti-theft device is cut through, e.g. with pliers, other / further "short circuits" or fault currents could occur for a short time, which could damage the device.

[0069] Example 3: If the software for operating the anti-theft device is activated on the device and the device is thus prepared for the "short circuit" of two contacts, plugging in a charging cable / data charging cable must not cause damage to the device.

[0070] In principle, common mobile devices often already offer self-protection functions – for example, to detect moisture in the connectors. Such self-protection functions are preferably used, activated, and / or enhanced to ensure the secure operation of the mobile device with the anti-theft device described here.

[0071] Preferably, the software offers the user different setting options as to whether the monitoring function should be activated automatically when an anti-theft device is detected, or only after confirmation of the automatic request, or only after a specific selection.

[0072] Preferably, the software offers the user all the usual setting options regarding the alarming actions, e.g. type and volume of the alarm tone, should the volume increase or remain the same, notification e.g. via email and / or WhatsApp and / or SMS, immediate or delayed.

[0073] Typically, mobile devices contain modules that enable (partial) decoupling of a mobile device's connector from other components. Such modules serve, for example, to protect the mobile device if moisture is present in the connector. The software described here preferably uses such functions to protect the mobile device once an alarm is triggered because tampering with the anti-theft device has been detected.

[0074] Which of the contacts in the mobile device's connector can be connected / bridged by the anti-theft device without causing a short circuit that could damage the device depends on the hardware and operating system of the respective device / device type. The app versions / software functions adapted to the device types and operating systems must be programmed accordingly. If the state in which two or more contacts are connected / bridged is not yet provided for in the program structure of the respective device, the app / software function presented here must implement this state in software.

[0075] The programming of the app / software function presented here must also provide automatic error checking. If the alarm function is enabled and thus the connection / bridging check is activated, plugging in a data / data charging cable must not cause damage to the mobile device. Conversely, if the app / software function is not enabled and the usual check for use of a data / data charging cable is performed, plugging in an anti-theft device, i.e., connecting / bridging contacts, must not cause damage to the device. In the event of an incorrect combination of device-side settings and hardware-side usage, appropriate protective functions / actions and user notifications must be programmed.Preferably, the app / software function presented here enables the automatic detection of an anti-theft device described here, makes the settings necessary for the operation of the anti-theft device, such as PIN assignments, and provides all technically necessary protocols, programs, programming, etc. on the mobile device that are required for the operation of the anti-theft device.

[0076] Essentially, the app / software function described here only queries properties of existing and known components (= existing charging / data connector), uses existing processors and cables / connections, and is operated via existing and known input options. Thus, unlike the current state of the art, no additional processors, memory, and / or cabling are used that must be made known to the device or operating system, which would lead to higher power consumption and thus a short backup time before the device shuts down due to insufficient battery charge.

[0077] Also to be described here are containers which are specially designed to be closed by one of the anti-theft devices described above, whereby the containers can have a hard or a soft outer shell (e.g. cans, boxes, cool bags, briefcases, backpacks, handbags).

[0078] Preferably, these containers have locking elements in the form of sliding handles, holes and / or slots through which the plug of an anti-theft device can be passed, but not the stopper, whereby opening of the container by an anti-theft device can be prevented.

[0079] Preferably, these containers have a special storage option or a special compartment for storing the mobile device, which is arranged in such a way that a mobile device securing the container can be placed therein, so that the mobile device can also be accommodated during the theft or locking security and can be protected, for example, from sunlight or beach sand.

[0080] Furthermore, it is advantageous if at least one line element is installed or incorporated into the outer shell of the containers in such a way that cutting or separating the container without damaging the line element is (almost) impossible, wherein the ends of the line element can be integrated into the monitoring of the electrical properties via an intermediate plug between the mobile device and the anti-theft device, whereby even cutting open a container leads to a recordable change in the electrical properties of the line element and thus to an alarm being triggered.

[0081] There are many application examples for the anti-theft device described here and the software for its operation. Examples include libraries, swimming pools, locker rooms, or hospitals. Another application is securing a mobile device to clothing (e.g., on a belt or backpack), which can prevent pickpocketing and the loss or forgetting of the mobile device (e.g., on a train). In conjunction with containers that are locked and secured simultaneously with the anti-theft device, many possibilities arise for protecting not only the mobile device but also other objects, such as car keys, wallets, or jewelry, from theft.

[0082] Due to the various design variants, the use of standardized plugs and connections, and the use of common input options on the device for switching the security on and off, the application possibilities and areas of application of the anti-theft device presented here are very extensive, and it can be used on all devices with these standardized features. Standardized, fixed anti-theft devices and standardized, fixed mounting options (e.g., standardized holes in cabinet walls or shelves) can be provided, which can be used by anyone who needs them. Anti-theft devices can be lent from one user to another. Additional objects can be secured with the anti-theft device.Lockers can be provided that are locked with the mobile device being secured at the same time. Any anti-theft device can be easily operated and used "blind," even in the dark. With the appropriate design, the user doesn't need to carry an additional anti-theft device if they already carry their multifunctional data / data charging cable.

[0083] The invention and the technical context of the invention are explained in more detail below with reference to the figures. The figures show preferred embodiments to which the invention is not limited. It should be noted in particular that the figures, and in particular the proportions depicted in the figures, are only schematic. They show:

[0084] Fig. 1 : an application of a first embodiment of the anti-theft device described;

[0085] Fig. 2: the first embodiment of the described anti-theft device in detail;

[0086] Fig. 3a to 3d: different embodiments of the anti-theft device described;

[0087] Fig. 4a to 4e: various embodiments of a cable of a described anti-theft device and designs or arrangements of a line element; Fig. 5: another application of a described anti-theft device;

[0088] Fig. 6: another embodiment of the anti-theft device described.

[0089] Fig. 1 shows an application of a first embodiment of the described anti-theft device 1. A structural element 18 can be seen, which can be, for example, a chair back, a sign or parasol post, a railing strut, or an element specially attached for this security purpose, or a similar element. The anti-theft device 1 is designed as a cable 6, which has a plug 3 at one end, which can be plugged into the connection 4 of a mobile device 2 (e.g. a mobile phone). At the other end of the cable 6 there is a feedthrough 7 designed as an eyelet 17. The cable 6 is passed through the feedthrough 7 formed by the eyelet 17. The feedthrough 7 or eyelet 17 is sized such that the plug 3 on the cable 6 can be passed through, but not the mobile device 2 connected to the plug 3. In this way, the cable 6 orWith the anti-theft device 1, a closed cable loop 8 is formed, which here is routed around the structural element 18 and which cannot be opened without destroying the cable 6 or the anti-theft device 1 or detaching the mobile device 2 from the plug 3. In this way, the mobile device 2 is secured to the structural element 18 and protected against theft.

[0090] Fig. 2 shows the anti-theft device 1 in detail. The plug 3 and the bushing 7 designed as an eyelet 17 at the ends of the cable 6 can be seen. In the cable 6, a continuous conductor element 5 is designed which forms a closed conductor loop and encloses the eyelet 17 and connects two contacts 9 of the plug 3 to one another. The mobile device 2 connected to the plug 3 can thus be used to monitor the electrical properties of the conductor elements 5, which change if the anti-theft device 1 is tampered with. The conductor elements 5 preferably extend through the entire cable 6 or through the entire anti-theft device 1. This ensures that a change in the electrical properties of the conductor element 5 occurs, regardless of where on the anti-theft device 1 a manipulation to release the cable loop 8 is carried out.

[0091] Fig. 3a to 3d show various alternative embodiments of the described anti-theft devices 1. The anti-theft devices 1 each have the plug 3 for connection to a port 4 of a mobile device 2 as well as line elements 5 which are connected to contacts 9 of the plug 3.

[0092] The embodiment shown in Fig. 3a has a passage 7, to which, for example, a chain 20 can be attached, which can be connected to a permanently installed structural element 18. The passage also enables the anti-theft devices 1 to be permanently screwed or mounted. Such anti-theft devices 1 can, for example, be permanently mounted in changing rooms to allow users of the changing rooms to secure their stored mobile devices 2 against theft.

[0093] The embodiment according to Fig. 3b has a base 19. This can be glued, screwed or installed, for example, on furniture, a wall or a windowsill, i.e. on a fixed structural element 18, in order to provide stationary anti-theft devices 1, for example in hospitals in front of examination rooms, in waiting rooms or in youth hostels. The at least one line element encloses any existing bushings for screwing and runs through the base in such a way that a forcible detachment of the base will possibly also lead to damage to the line element. Fig. 3c shows an embodiment with a bushing 7 or eyelet 17 formed directly on the plug 3 or built into the plug. This embodiment can also be used, for example, to attach the anti-theft devices 1 directly to a permanently installed structural element 18 or, for example,to fix it with a bicycle lock in order to then secure a mobile device 2.

[0094] The design variant of the anti-theft device 1 according to Fig. 3d has a stopper 15 and a feedthrough 7 designed as an eyelet 17. Plug 3 and cable 6 can only be guided up to the stopper 15 through corresponding holes, slots or openings of locking elements 16 or structural elements 18. A plugged-on mobile device 2 (not shown here) prevents the return. This means that the anti-theft device 1 can be fixed to some structural elements 18 without forming a cable loop 8. Furthermore, the preferably short section between the mobile device 2 and the stopper 15 can prevent the locking elements 16 from being pushed apart and thus the opening of, for example, a backpack, a bag, a cooler bag or a briefcase, provided these have locking elements 16 with correspondingly dimensioned openings. Other objects, e.g.A key ring, for example, can be attached to this cable section. This design variant is more universally applicable, for example, as shown in Fig. 1 and Fig. 5.

[0095] Fig. 4a to 4e show different embodiments of a cable 6 of a described anti-theft device 1, wherein in each case a section of the cable 6 with its internal structure and the line elements 5 contained therein and their different arrangement, laying and design is shown.

[0096] Fig. 4a shows a variant in which the conductive elements 5 are designed as an inner conductive element 11 and an outer conductive element 12, wherein the outer conductive element 12 surrounds the inner conductive element 11 and wherein the outer conductive element 12 is preferably additionally surrounded by a sheath 13. A dielectric material 10 is arranged between the conductive elements 11 and 12, which dielectric material 10 electrically separates the inner conductive element 11 from the outer conductive element 12. The inner conductive element 11, the dielectric material 10 and the outer conductive element 12 together form an electrical circuit and in particular an electrical circuit that acts like a capacitor or has an electrical capacitance. Any attempt to destroy the cable 6 will inevitably result in a change in the electrical properties of this electrical circuit and in particular a change in the electrical capacitance.This can be detected by a connected mobile device 2.

[0097] In the embodiment according to Fig. 4b, one or two electrical conducting elements 5 are twisted or intertwined in the cable 6 and preferably arranged in a matrix material 14. Preferably, it is not possible to see from the outside of the cable 6 where the electrical conducting elements 5 are arranged within the matrix material 14. This can make it considerably more difficult for an attacker to find a way to sever the cable 6 and simultaneously bridge the conducting elements 5 in order to prevent the mobile device 2 from detecting the severing of the cable 6.

[0098] Fig. 4c shows a variant in which the feedthrough 7 is created by splitting the cable 6, wherein the line element 5 or the line elements 5 are arranged twisted or intertwined at least before and after the split in order to prevent an enlargement of the feedthrough 7.

[0099] Fig. 4d shows an embodiment variant in which the feedthrough 7 is created by crossing the cable 6, wherein the line element 5 or the line elements 5 are arranged or crossed in the region of the crossing in such a way that it is not possible to separate the crossing point without damaging a line element 5.

[0100] Fig. 4e shows an embodiment of the anti-theft device 1 in which a line element 5 only achieves the property of a “closed line element” by bringing together the further plug 21 and the connection socket 22 on the anti-theft device 1, wherein the cable 6 forms a feedthrough 7 or eyelet 17 after the bringing together.

[0101] Fig. 5 shows another application of a described anti-theft device 1 with a stopper 15, as shown, for example, in Fig. 3d. Here, several (here two) locking elements 16 are used between the mobile device 2 connected to the plug 3 with the connector 4 and the stopper 15. These locking elements can each belong to an object to be secured, or both can be used together to lock, for example, a backpack, a bag, a cooler bag, or a briefcase. The anti-theft device then replaces, for example, a padlock.

[0102] The principle can also be applied to other applications.

[0103] Fig. 6 shows a variant of the anti-theft device 1 with a stopper 15, a bushing 7 created by splitting the cable 6, a plug 23 provided with a function switch, an integrated storage medium 24 and a mechanical unplugging lock 25. This version can be used as an anti-theft device 1, as a conventional data / data charging cable and as a storage medium, depending on the switch position of the plug with function switch 23.

[0104] Known anti-theft devices according to the prior art regularly require the operation of an input device for entering a passphrase (e.g., a combination lock or an input device for entering a number). This complicates the use of the anti-theft device in the dark. Anti-theft devices based on a token (e.g., a key as a token) carry the risk of loss of the token. Such anti-theft devices are therefore subject to further limitations. The anti-theft device 1 described here can be used in many areas where other anti-theft devices cannot be used. Thus, a novel anti-theft device 1 with maximum flexibility is proposed, which, due to the exclusive use of already standardized components and operating elements, is suitable for establishing a standard for securing mobile devices 2.
