Description

The invention relates to a novel anti-theft device for securing a mobile device against theft and loss.

Due to their closed, flat outer shell, cell phones and most mobile devices cannot easily be secured by inserting, hooking or installing locks, chains, etc., as is the case with bicycles or cars.

Numerous apps and hardware components offer alternative backup options in different ways to solve this technical problem. But, 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 an uncomplicated and therefore self-evident security option is strong among almost all users of mobile devices, the need for this has actually grown with the increasing popularity and often quite high value of mobile devices and the increasingly technological world suggests otherwise, is still there The majority of mobile devices, for example in changing rooms, on the beach, in youth hostels, in offices or in hospital rooms, are always completely unsecured and ready for any thief to reach.

There are apps that trigger alarming actions as soon as the phone is moved. Such apps have the disadvantage that an alarm is triggered even if the cell phone is accidentally moved by the owner or another person or, for example, by the movement of a train. The owner himself has to turn off the alarm before moving the cell phone, and in many situations this is not possible or very inconvenient.

There are apps that trigger alarming 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 a power outlet or a PC available, which is not the case in most places where you want to secure a mobile device.

Another option is to use apps that detect whether someone is trying to unlock the device. If attempts are unsuccessful, the alarming actions are triggered. Such approaches have the disadvantage that an alarm is triggered even if the owner makes a failed attempt. In addition, the cell phone can be stolen without an alarm being triggered. Whether the alarm is triggered at a later point in time depends on many factors, e.g. the technical skills of the thief.

There are many apps that are only used after the theft has occurred and been noticed. They give the owner different options. Common options include, for example, locating the stolen cell phone, accessing data or deleting it remotely, triggering an alarm on the cell phone, etc. Since these apps do not provide anti-theft protection, but are only used after the theft, this is a completely different approach.

Even state-of-the-art anti-theft devices that only work with additional hardware are not widely used because they too often restrict the spontaneous use of the mobile device, are not easy to use and/or cannot be used in a sufficient number of situations.

There is fundamentally room for improvement when it comes to anti-theft protection for mobile devices, such as cell phones, eBooks or laptops.

It is therefore the object of the present invention to at least partially solve the problems described with reference to the prior art. This object is achieved with the invention according to the features of the independent patent claims. Further advantageous refinements are specified in the dependently formulated patent 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 combines the individual features with one another in a technologically sensible manner and thus arrives at further refinements of the invention.

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 insertion into a port of the mobile device, with at least one continuous line element surrounding the feedthrough being arranged in the entire anti-theft device, which is connected to the plug is connected in such a way that software operated on the mobile device can register any change in the electrical properties of the line element, with both the insertion and unplugging of the plug as well as the cutting of the line element each representing a change in the electrical properties and thus a change that can be registered , thereby preventing theft security device provides an electronically secured feedthrough connected to the mobile device, which enables the mobile device to be attached, whereby at least the mobile device can be protected from theft. Instead of the implementation or in addition, the anti-theft device can have a base, which enables the anti-theft device to be permanently attached, for example to furniture or walls, whereby the at least one line element must be installed in the base in such a way that damage to the base also results in damage to the line element leads.

It is advantageous if the anti-theft device is a cable with a plug connected to it for insertion into a port of the mobile device and the anti-theft device further has a feedthrough through which the plug can be passed to form a cable loop, the feedthrough being designed in such a way that that a mobile device connected to the plug prevents the cable loop from being detached, whereby the at least one continuous line element must completely enclose the bushing and thus the cable loop.

The term “mobile device” refers in particular to cell phones and cell phones but also laptops, tablets, notebooks, iPads, MP3 players, mobile speakers, photo and video cameras, etc. In particular, this includes all mobile devices that have at least one data connection/charging socket or charging socket, 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 that Drawing patterns on a display, fingerprint recognition, facial recognition, etc.

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

The term “line element” refers to electrical lines that can in particular be installed in a cable, particularly preferably electrically conductive wires.

The cable loop described can in particular be placed around a permanently installed structural element or an attachment point in order to secure the mobile device connected to the anti-theft device or the plug. Fastening points on all fixed structural elements that cannot be moved or can be difficult to move are useful, e.g. stair railings, hospital beds, sun loungers, etc.

The cable loop cannot be dissolved without a separation of the connection between the plug and the connection or damage to the anti-theft device, i.e. not without a change in the electrical properties of the at least one line element that can be registered by the software, which in turn triggers an alarming reaction on the mobile device would.

The most important function of the software operated on the mobile device to monitor the anti-theft device connected to the port is the function of monitoring the electrical characteristics, that is, whether the connector of the anti-theft device is plugged in or unplugged and whether the anti-theft device is damaged, cut or damaged is manipulated in another way. After inserting the anti-theft device connector, the monitoring function of the software can be activated. In order to then unplug the device without triggering an alarm, an unlocking measure is necessary - for example, entering a code or using facial recognition. Every unplugging and every damage to the anti-theft device with a concomitant change in the electrical properties of the at least one line element inevitably leads to the alarm being triggered when the monitoring function is activated.

It is also advantageous if at least one line element extends through the cable, enclosing the bushing, so that if the cable is cut to dissolve the cable loop without unplugging the plug from the connection, an impairment of the line element occurs, which is caused by one on the mobile Device-operated software can be recognized.

A line element is designed in particular 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 impaired.

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.

Contacts are in particular contact pins or contact surfaces within the plug, which interact with corresponding contacts in the connection in order to bring about an electrical connection of the anti-theft device to the mobile device.

It is also advantageous if at least two line elements in the anti-theft device are separated from one another by at least one dielectric material, the dielectric material and the at least two line elements forming a circuit whose electrical properties can be monitored by the software operated on the mobile device, whereby Cutting the cable causes a change in the electrical properties that can be recorded by the software.

The electrical conduction elements and the dielectric material preferably form an electrical circuit, the electrical properties of which can be monitored using the software on the mobile device. In particular, this circuit has capacitive properties and therefore acts at least partially as a capacitor. The line elements are preferably arranged in such a way that manipulation of the anti-theft device causes a change in this electrical circuit, which can be recognized by the software operated on the mobile device and can thus be used as a reason to trigger an alarm.

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

In such an arrangement, the inner line element is protected from the outside by the outer line element. It is nearly impossible for someone attempting to tamper with the anti-theft device to reach the inner conduit member without first interfering with the outer conduit member. It has been found that conductors lying one inside the other provide very good protection against manipulation of the anti-theft device, which cannot be detected by the software operated on the mobile device.

Very particularly preferably, the dielectric material is arranged between the inner line element and the outer line element. A capacitive circuit can thus be formed.

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

In addition, it is advantageous if the at least one line element is arranged twisted in the cable at least in sections. With a line element that only runs parallel back and forth, the bushing can undesirably be enlarged. If the at least one line element is twisted at least in front of and behind the bushing, increasing the size of the bushing without damaging the line element becomes almost impossible.

In this context, the line elements are particularly preferably embedded in a matrix material and it is preferably not visible from the outside where or how the line elements are arranged in the cable or in the anti-theft device. This also makes manipulation of the anti-theft device more difficult.

It is also advantageous if the plug is a USB type plug.

It is particularly advantageous if the plug is a USB-C type plug.

These are common connector types. With such connectors, the anti-theft device can be used in conjunction with most mobile devices.

It is further advantageous if the bushing is an eyelet which is firmly connected to the cable.

Particularly preferably, an eyelet is arranged at one end of the cable in order to be able 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.

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

It is particularly advantageous if the anti-theft device has the complete cabling and the two necessary plugs for operation as a data and / or data charging cable, with at least one of the plugs having a mechanically operated circuit that allows a change in function from the anti-theft device to data and / or data charging cable possible.

It is further advantageous if the at least one plug with the mechanically operated circuit for the function change in the “anti-theft device” switch position mechanically prevents this plug from being inserted into a connection.

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

It is further advantageous if the number of installed line 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 memory or USB stick without switching .

It is further advantageous if at least one electronic component is installed in the anti-theft device, which identifies the anti-theft device as such for the mobile device, whereby a change in the identification must also take place in the event of a possible switch to another function (chips for electronic marking). .

It is further advantageous if the anti-theft device has, in addition to the one necessary plug for connection to a device, a further plug and a matching connection socket, only by merging these an interruption in the at least one continuous line element is closed and at the same time the interruption for fastening the anti-theft device necessary bushing or cable loop is closed.

It is further advantageous if at least one of the plugs of the anti-theft device has a mechanically operated mechanism that makes it possible to block the plug from being unplugged from the connection socket of the device. This means that accidental disconnection and thus accidental triggering of the alarm can be prevented and the anti-theft device can be used to protect against the device being lost or forgotten, even without switching on the monitoring function on the device.

In addition, 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.

A stopper makes it possible in particular to limit threading through the anti-theft device. As a result, the anti-theft device can be attached to any hole or slot in a structural element through which the plug, but not the stopper, can be guided and, for example, bushings can be used between a stopper and the mobile device, which are parts of other structural elements, to also protect them secure it with the anti-theft device and/or lock it. This could be, for example, slider handles on a backpack zipper.

This means that the anti-theft device can fulfill several tasks at the same time: the contents of the backpack are protected against theft by the secured closure, the backpack itself is attached to the anti-theft device and is therefore protected from theft and at the same time the mobile device is protected from theft. There are many other possible applications.

Furthermore, it is advantageous if the anti-theft device has a base which enables the anti-theft device to be (permanently) attached to a structural element.

It is further advantageous if the cable of the anti-theft device can be wound up at least partially in the plug housing or an additional housing or can be wound up 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 simultaneously take on the function of a stopper.

Also to be described here is software for installation on a mobile device and set up to operate a described anti-theft device, the software being set up 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 otherwise tampered with. After inserting the connector of the anti-theft device, the monitoring function can be activated the software can be activated. In order to then unplug the plug without triggering an alarm, an unlocking measure is necessary, whereby the measure to be carried out to unlock the device can be, for example, entering a code or using facial recognition and/or by entering a code that is only specified to end the monitoring function Codes can be done. Every unplugging and every damage to the anti-theft device with a concomitant change in the electrical properties of the at least one line element inevitably leads to the alarm being triggered when the monitoring function is activated.

It should be pointed out that the special advantages and design features described in connection with the anti-theft device described above can also be applied and transferred to the software described in more detail below.

The software is preferably available as an app in common online stores for providing apps for mobile devices and can be installed on mobile devices from such online stores. The software can also be provided in any other way, for example on a data carrier or already pre-installed on a mobile device in the delivery state.

Preferably, the software is set up to emit an alarm signal and/or a notification if the plug of the anti-theft device is pulled out of the connection of the device when the monitoring function is switched on and if a change in the monitored electrical properties of a line element of the anti-theft device is registered, which also includes a cutting of the Line element represents a recordable change.

Alarm signals can be issued in a variety of ways - for example in the form of noises, vibrations and/or in the form of messages that are sent to recipients.

The software preferably enables the monitoring function to be switched off by unlocking the mobile device in the usual way.

The software preferably has an unlocking function, with which, for example, a pin can be queried on the mobile device, facial recognition and/or fingerprint recognition can be carried out in order to only switch off the monitoring function without unlocking the entire device.

In addition, the software is preferably set up to monitor an electrical property of the line element and to detect a change in the electrical property that suggests manipulation of the anti-theft device.
In addition, the software is preferably set up to activate a self-protection function of the mobile device when a change in the electrical property can be detected that is due to manipulation of the anti-theft device.

The software preferably offers the user different setting options as to whether the monitoring function should be switched on automatically when an anti-theft device is detected or only after confirmation of the automatic request or only after a targeted selection.

The software preferably offers the user all the usual setting options regarding the alarming actions, e.g. type and volume of the alarm tone, if the volume should increase or remain the same, notification e.g. by email and/or WhatsApp and/or SMS, immediately or with a time delay.

Modules are usually implemented within mobile devices that enable a (partial) decoupling of a connection of the mobile device from other components of the mobile device. Such modules are used, for example, to protect the mobile device if moisture occurs in the connection. The software described here preferably uses such functions to protect the mobile device as soon as an alarm is activated because manipulation of the anti-theft device has been detected.

Which of the contacts in the connection of the mobile device can be connected/bridged together by the anti-theft device without causing a short circuit that is harmful to 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 that 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 the software.

The programming of the app/software function presented here must also provide automatic error checking. Is the If the alarm function is switched on and the test for connection/bridging of contacts is activated, plugging in a data/data charging cable must not lead to damage to the mobile device. Conversely, if the app/software function is not activated and the usual check for use of a data/data charging cable is carried out, inserting an anti-theft device, i.e. connecting/bridging contacts, must not lead to damage to the device. If there is an incorrect combination of device settings and hardware use, appropriate protective functions/actions and also instructions for the user must be programmed.

The app/software function presented here preferably enables the automatic recognition of an anti-theft device described here, makes the settings necessary to operate the anti-theft device, such as pin assignments, and makes all the protocols, programs, programming, etc. technically necessary on the mobile device available , which are required to operate the anti-theft device.

Also to be described here are containers which are particularly designed for closure by one of the previously described anti-theft devices, whereby the containers can have a solid or a soft outer shell (e.g. cans, boxes, cool bags, briefcases, backpacks, handbags).

These containers preferably have locking elements in the form of slide handles, holes and/or slots through which the plug of an anti-theft device can be passed, but not the stopper, whereby the container can be prevented from being opened by an anti-theft device.

These containers preferably 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 there so that the mobile device can also be stored during theft or locking protection e.g. can be protected from sunlight or beach sand.

In addition, it is advantageous if at least one line element is installed or incorporated into the outer shell of the container in such a way that cutting or separating the container is (almost) not possible without damaging the line element, with the ends of the line element being connected via an intermediate plug between The mobile device and the anti-theft device can be integrated into the monitoring of the electrical properties, whereby cutting open a container also leads to a recordable change in the electrical properties of the line element and thus to an alarm being triggered.

There are many application examples for the anti-theft device described here and the software to operate it. For example in libraries, swimming pools, changing rooms or hospitals. Another area of application is, for example, securing the 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 simultaneously locked and secured with the anti-theft device, there are many possibilities for protecting not only the mobile device but also other items, such as car keys, wallets or jewelry, from theft.

The invention and the technical environment of the invention are explained in more detail below with reference to the figures. The figures show preferred exemplary embodiments to which the invention is not limited. It should be particularly noted that the figures and in particular the size relationships shown in the figures are only schematic. Show it:

1 shows an application of a first embodiment variant of the anti-theft device 1 described. A structural element 18 can be seen, which, for example, is a chair back, a sign or parasol post or a strut of a railing or an element or element specially attached for this security purpose can be 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 cell phone). At the other end of the cable 6 there is a bushing 7 designed as an eyelet 17. The cable 6 is guided through the bushing 7 formed by the eyelet 17. The size of the bushing 7 or eyelet 17 is 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 or with the anti-theft device 1 a closed cable loop 8 is carried out, which is guided here 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.

2 shows the anti-theft device 1 in detail. The plug 3 and the bushing 7 designed as an eyelet 17 can be seen at the ends of the cable 6. In the cable 6 there is a continuous line element 5, which forms a closed conductor loop and encloses the eyelet 17 and two contacts 9 of the plug 3 connects with each other. With the mobile device 2 connected to the plug 3, electrical properties of the line elements 5 can be monitored, which change if the anti-theft device 1 is manipulated. The line 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 line element 5 occurs, regardless of where on the anti-theft device 1 a manipulation is carried out to dissolve the cable loop 8 .

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

The design variant according to 3a has a feedthrough 7 to which, for example, a chain 20 can be connected, which can be connected to a permanently installed structural element 18. The implementation also makes it possible to screw or mount the anti-theft devices 1 firmly. Such anti-theft devices 1 can, for example, be permanently installed in changing rooms in order to give users of the changing rooms the opportunity to secure their stored mobile devices 2 against theft.

The design variant according to 3b has a base 19. This can be glued, screwed or installed, for example, on furniture, a wall or a window sill, 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 screw connection and passes through the base in such a way that a violent detachment of the base will, if possible, also lead to damage to the line element.

3c shows an embodiment variant with a bushing 7 or eyelet 17 formed directly on the plug 3 or installed on the plug. This embodiment variant can also be used, for example, to fix the anti-theft devices 1 directly to a permanently installed structural element 18 or, for example, with a bicycle lock, to then secure a mobile device 2.

The embodiment variant of the anti-theft device 1 according to 3d has a stopper 15 and a bushing 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 in locking elements 16 or structural elements 18. An attached mobile device 2 (not shown here) prevents the return. As a result, the anti-theft device 1 can be fixed to some structural elements 18 even without forming a cable loop 8. Furthermore, the preferably short section between the mobile device 2 and the stopper 15 can prevent locking elements 16 from being pushed apart and thus the opening of, for example, a backpack, a bag, a cool bag or a briefcase, provided these have locking elements 16 with appropriately sized openings feature. Other objects, such as a bunch of keys, can also be fixed on this cable section. This design variant can be used more universally - for example as in the 1 and 5 is shown.

4a to 4e show different embodiment variants of a cable 6 of a described anti-theft device 1, each showing a section of the cable 6 with its internal structure and the line elements 5 and contained therein Their different arrangement, laying and execution are shown.

4a shows an embodiment variant in which the line elements 5 are designed as an inner line element 11 and outer line element 12, the outer line element 12 surrounding the inner line element 11 and preferably the outer line element 12 being additionally surrounded by a jacket 13. A dielectric material 10 is arranged between the line elements 11 and 12 and electrically separates the inner line element 11 from the outer line element 12. The inner line element 11, the dielectric material 10 and the outer line element 12 together form an electrical circuit and in particular an electrical circuit which acts like a capacitor or which has an electrical capacitance. When attempting to destroy the cable 6, a change in the electrical properties of this electrical circuit inevitably occurs and in particular a change in the electrical capacity. This can be recognized by a connected mobile device 2.

In the embodiment variant according to 4b is an electrical line element 5 or two electrical line elements 5 are twisted or twisted into one another in the cable 6 and are preferably arranged in a matrix material 14. Preferably, the cable 6 cannot be seen from the outside, where the electrical line elements 5 are arranged within the matrix material 14. This can make it considerably more difficult for an attacker to find a way to cut the cable 6 and at the same time bridge the line elements 5 in order to prevent the mobile device 2 from detecting the cutting of the cable 6.

4c shows an embodiment variant in which the bushing 7 is created by splitting the cable 6, the line element 5 or the line elements 5 being arranged twisted or twisted into one another at least before and behind the split in order to prevent the bushing 7 from enlarging.

4d shows an embodiment variant in which the bushing 7 is created by crossing the cable 6, the line element 5 or the line elements 5 being arranged or crossed in the area of the crossing in such a way that the crossing point cannot be separated without damaging a line element 5 is possible.

4e shows an embodiment of the anti-theft device 1, in which a line element 5 only achieves the property of “closed line element” by bringing together the further plug 21 and the connection socket 22 on the anti-theft device 1, with the cable 6 having a bushing 7 or eyelet 17 after being brought together trains.

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

The principle can also be transferred to other applications.

6 shows an embodiment 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 device 25. This version can be used as an anti-theft device 1, as a conventional one Data-/

Data charging cable and can be used as a storage medium, depending on the switch position of the plug with function switching 23.
