DETAILED DESCRIPTION OF EMBODIMENTS

[0038] Reference is made to FIG. 1 illustrating, by way of a block diagram, a non-limiting example of a data protection system 100 configured for mounting/attaching on a mobile device 10, to protect the privacy of a user/owner of the mobile device 10. Accordingly, the data protection system 100 is an external system configured to be attached to the mobile device housing and it is not an internal system of mobile device. Therefore, the data protection system 100 is universal and can be adapted to the specific mobile device. The data protection system 100 is configured for protecting privacy of a user of the device against remote hacking of the device's software and/or hardware, and specifically when the mobile device is not in use by the user but located therewith.

[0039] The data protection system 100 can be adapted to protect the privacy of the device's user and prevent eavesdropping by including one or more of the following sub-systems, depending on the facilities included within the mobile device, as explained above: audio data protecting system 110 aimed at preventing obtaining/stealing audio data originating from surroundings of the device, visual data protecting system 120 aimed at preventing stealing visual data (images/videos) originating from surroundings of the device, location data protecting system 130 aimed at preventing identifying location of the device based on location-based data originating from location of the device. It is noted that the data protection system 100 can include only one, any two or more of the sub-systems above and this depends on the mobile device functionality or on the desired application.

[0040] In some embodiments, the data protection system 100, including any sub-system thereof, is configured optionally for mounting on the mobile device by a case 200 configured to be attached to the mobile device. Accordingly, in some embodiments of the invention, as will be exemplified further below, a case configured for mounting on the mobile device, for the purpose of physical protection and/or design matters, includes the data protection system 100 with any combination of the sub-systems.

[0041] Being external to the mobile device, the data protection system 100 is designed to be operable totally or partially independently from the mobile device. Therefore, the data protection system 100 has its own control/processing unit(s) and power supply. In some embodiments, the data protection system may depend for its activity on the mobile device facilities, as will be explained herein further below.

[0042] As shown, the data protection system 100 includes a control/processing unit 140 configured and operable to control the function(s) of the data protection system 100 and any of the sub-systems. It should be noted that the control/processing unit 140, while being shown as a single unit in the block diagram of FIG. 1, should be interpreted broadly. In some embodiments, a single unified processing unit, as shown, is provided. In some other embodiments, each one of the audio, visual, and location data protection systems has its own processing unit. In some embodiments, some of the audio, visual, and location data protection systems are connected to a single processing unit. Whenever the processing unit is mentioned herein, it can be employed in any one of the above described configurations.

[0043] Also, the data protection system 100 includes a power supply unit 150 configured and operable to provide the data protection system 100 and any of the sub-systems with the power needed for executing the different actions. Again, the power supply unit 150, while being shown as a single unit in the block diagram of FIG. 1, should be interpreted broadly. In some embodiments, a single unified power supply unit, as shown, is provided. In some other embodiments, each one of the audio, visual, and location data protection systems has its own power supply unit. In some embodiments, some of the audio, visual, and location data protection systems are connected to a single power supply unit. Whenever the power supply unit is mentioned herein, it can be employed in any one of the above described configurations. In some embodiments, the power supply unit 150 can be a battery. The battery can be disposable (single-use) or rechargeable (reusable). In some embodiments, the power supply unit includes a power cord configured to be connected to a power output of the mobile device and enable feeding the data protection system 100 with power from the internal power unit of the mobile device and/or charging the rechargeable battery of the power supply unit 150 of the data protection system.

[0044] It is noted that the data protection system can be protected by one or more protection layers such that its activation and deactivation is possible only by the user/owner or other authorized individual. For example, the data protection system can be protected by a passcode.

[0045] Reference is made to FIGS. 2A-2B illustrating, by a way of block diagrams, the data protection system 100 including the audio data protection system 110 (sometimes referred to herein as the ambient audio data protection system) configured for protecting the privacy of the mobile device's user/owner by preventing a third party taking control remotely of the mobile device from eavesdropping to audio in the surroundings of the mobile device 10, such as a conversation between the user and other(s) taking place near the mobile device and in the range of the microphone(s) of the mobile device.

[0046] In some embodiments, the specifically designed audio signals are configured to include one or more frequencies corresponding to the frequencies of human voice, thereby preventing a third party from isolating the ambient audio in the surroundings from the overall audio signals collected by the microphone.

[0047] As shown in the non-limiting example of FIG. 2A, the audio data protection system 110 includes one or more acoustic elements (e.g. speakers) configured to be positioned in the vicinity of one or more microphones of the mobile device, the acoustic element(s) is (are) configured and operable to generate acoustic waves/signals to be collected by the microphones of the device. In this specific example, three acoustic elements 112A-112C are placed beside three device's microphones 12A-12C respectively. The acoustic elements 112A-112C are placed near the microphones such that when they are activated to produce acoustic waves they affect the overall audio signal collected by the microphones such that they prevent isolating the ambient audio (the audio originating from the surroundings) from the acoustic signals they produce, and when they are deactivated they enable proper functionality of the microphones. Accordingly, in some embodiments, the acoustic elements are attached to the microphones using specifically designed acoustic material that enables the above. In some embodiments, the acoustic element(s) and the microphone(s) are located within an isolated acoustic cell, for example 116A, that is designed and configured to enable proper function of the microphone(s) when the ambient audio data protection system is deactivated, and on the other side amplify the specifically designed audio signals emitted towards the microphone(s), thereby enabling to keep the specifically designed audio signals at low volume.

[0048] The processing unit 140 is configured and operable to produce a random noise signal that is transferred to the acoustic elements that generate corresponding random noise acoustic waves that are collected by the microphones and prevent isolating the ambient audio from the overall audio signal including the random noise and the ambient audio. For example, the random noise is an acoustic signal including a plurality of random frequencies and/or amplitudes and/or phases and/or sequences. In some embodiments, he random noise acoustic waves are configured to cause saturation of the device's microphones preventing them from or minimizing their ability to collect the ambient audio. The random noise is chosen such that it is hardly noticeable/discernible by the device's user and his/her companions. In some embodiments, the ambient audio data protection system 110, possibly through the processing unit 140, is configured to emit different specifically designed audio signals through the different acoustic elements such that each microphone of the mobile device is subjected to a different specifically designed audio signal, thereby increasing variability between the different audio signals collected by the different microphones and minimizing risk of isolating the ambient audio in the surroundings from the overall collected audio in each microphone.

[0049] In FIG. 2B, another non-limiting example of the audio data protection system 110 is shown. Here, the audio data protection system 110 includes a single (central) acoustic element 112 located somewhere on the mobile device with one or more audio channels configured and operable to transmit the random noise acoustic waves from the acoustic element 112 to the respective one or more microphones of the mobile device. Again, in this example, three audio channels 114A-114C are configured to transmit the acoustic waves from the acoustic element 112 to the three microphones 12A-12C of the mobile device.

[0050] In some embodiments, the audio channel is structured and/or includes an acoustic material that amplifies the specifically designed acoustic signals along the way.

[0051] It is appreciated that the above non limiting examples of the audio data protection should not limit the broad aspect of the invention. For example, it can be that a single acoustic element is coupled to more than one microphone of the mobile device if the microphones are in close vicinity to each other. In another example, a single audio channel splits along the way to more than one audio channel each coupled to one or more microphones. In another example, a combination of the examples of FIGS. 2A and 2B can be provided.

[0052] The configuration in FIG. 2B can be advantageous in matching the audio data protection system 110 to various models of the mobile device that can have different designs and different locations of the microphones, specifically when the data protection system is mounted on a protective case. The configuration in FIG. 2B enables using a modular case that is configurable to suit various mobile device. In this instance, the case may include a central part configured to be attached to a central portion of the plurality of models of the mobile device, and at least one top part and at least one bottom part configured to attach to one mobile device's model of the plurality of models of the mobile device. The central part accommodates the single acoustic element 112 and the top and bottom parts that match the housing/design of a specific mobile device model accommodate the audio channels that convey the acoustic waves to the respective microphones. This way, the central part of the case is universal while the user replaces only the top and bottom parts whenever he/she changes the mobile device model.

[0053] Reference is made to FIG. 3 illustrating, by way of a block diagram, a non-limiting example of the data protection system 100 including the visual data protection system 120 configured for preventing eavesdropping to visual data at the surroundings of the mobile device by taking control of the camera systems of the mobile device. The visual data protection system 120 includes a shutter mechanism configured to selectively cover the camera system(s) of the mobile device and prevent the camera system(s) from collecting images of surroundings of the mobile device. The shutter mechanism includes at least one shutter element configured to cover/uncover one or more camera systems of the mobile device. In one example, a single shutter element is configured to cover/uncover all of the camera systems of the mobile device, e.g. front and back camera systems. In the described non-limiting example, the mobile device includes two camera systems 14A and 14B, e.g. front and back camera systems in a smartphone or tablet, to which two shutter elements 122A and 122B are coupled respectively. The shutter element is displaceable between a first position in which it uncovers the camera system and a second position in which it covers the camera system. As shown, the shutter element 122A is displaceable between a first position 122A1 in which it uncovers the camera system 14A and a second position 122A2 in which it covers the camera system 14A. Similarly, the shutter element 122B is displaceable between a first position 122B 1 in which it uncovers the camera system 14B and a second position 122B2 in which it covers the camera system 14B.

[0054] In some embodiments, the shutter element is mechanically displaceable between the first and second positions by hand or by a button (not specifically shown). In some embodiments, the shutter element is electronically displaceable between the first and second positions, e.g. by a switch 124. Each shutter element may have its own button/switch or a common button/switch may control some or all of the shutter elements.

[0055] In some embodiments, activating the visual data protection system 120 (when the shutter element is displaced from the first position to the second position) may also activate other included parts of the data protection system 100, such as the audio data protection system 110A, and vice versa. This may be controlled by the control unit(s) 140 that is connected to all included different systems.

[0056] In some embodiments, whenever the data protection system 100 includes both of the audio and visual protection systems 110 and 120, and while not specifically shown, at least one shutter element carries at least one of an acoustic element and an audio channel, of the ambient audio protection system, being located or terminated in vicinity of at least one microphone adjacent the camera system, such that when the shutter element is moved to the second position covering the camera system, the acoustic element and/or the audio channel enable preventing eavesdropping to the ambient audio in the surrounding of the mobile device.

[0057] Reference is made to FIG. 4 illustrating, by way of a block diagram, a non-limiting example of the data protection system 100 including the location data protection system 130 configured for preventing eavesdropping to location data of the mobile device by taking control of the location determination system(s) 16 of the mobile device.

[0058] As shown, the location data protection system 130 includes a location data generation unit 132, e.g. a GPS signal generator, configured to selectively generate localized, near-field, directional and weak location (GPS) signals (that do not affect other nearby mobile devices carrying their own location determination systems), to be collected by the location determination system 16 (e.g., a GPS receiver) of the mobile device, when the location data generation unit 132 is attached in close, specifically closest, proximity to the location determination system 16 of the mobile device, interrupt with/block location determination signals received from a remote location data generator (e.g., a GPS generator satellite) and prevent determining the location of the mobile device, specifically prevent isolating the location determination signals from overall location data signal collected by the location determination system 16 of the mobile device.

[0059] In some embodiments, the location data generation unit is configured and operable to generate the location signals (e.g., via the control unit 140) being indicative of a constant location, generally different than the actual location of the mobile device. In some embodiments, the location data generation unit is configured and operable to generate the location signals being indicative of a moving location of the mobile device, e.g. resemble a route extending between two or more points during a predetermined period of time.

[0060] In a non-limiting experiment performed by the inventors, the following conditions were examined and results were confirmed:

[0061] the location data generation unit was operated to emit signals in the frequency range 1164-1610 MHz, up to +10 dBm signal power; as a result the signal from a GPS generator satellite was blocked both indoor and outdoor; GSM, Bluetooth and Wifi transceivers were not affected in the mobile device or other device with a 10 cm distance away; no location determination system of the other devices was affected.

[0062] Reference is made to FIGS. 5A-5B showing a non-limiting example of a casing 200A, for the mobile device, carrying a non-limiting example of the data protection system. The casing 200A is intended for mounting on the mobile device and carries, in this non-limiting example, both of the ambient audio data protection system and the visual data protection system, integrated therein. As shown, the ambient audio data protection system includes two acoustic elements 112A and 112B located on the bottom and top of the case 200A respectively and intended to be in close proximity to the microphones of the specific mobile device when received within the casing 200A. Also, the casing carries the control unit 140 and the power supply unit 150 configured and operable as described above. As shown in FIG. 5A, illustrating the front side of the case 200A, a shutter element 122A is provided on the upper side and intended for selectively covering the front camera system of the mobile device. The shutter element is shown in its first position 122A1 uncovering the camera system and enabling the user to use it as needed. FIG. 5B illustrates the back side of the case 200A, a shutter element 122B is provided on the upper side and intended for selectively covering the back (main) camera system of the specific model of the mobile device. The shutter element is shown in its first position 122B1 uncovering the camera system and enabling the user to use it as needed.

[0063] As mentioned above, the casing and locations of the data protection system elements is adapted to the specific mobile device model, enabling optimal functionality for protecting the privacy of the user.

[0064] In FIG. 6 another non-limiting example of a casing 300, for the mobile device, carrying a non-limiting example of the data protection system, is shown. Also in this non-limiting example, both of the ambient audio data protection system and the visual data protection system are integrated in the casing 300, together with the control unit 140 and the power supply unit 150. In this example, to enable extra manufacturing flexibility, the casing 300 is divided into three parts, a middle, central part 300A, a top part 300B and a bottom part 300C. This configuration allows using the central part 300A as a universal part that can match a plurality of mobile devices, such that only the top and bottom parts are adapted to the specific mobile device's model.

[0065] In this example, the ambient audio data protection system is configured as in FIG. 2B above, where a central acoustic element 112 is carried by the central part 300A and connected to the microphones (not shown) on the device by audio channels 114A and 114B extending from the central part 300A to the top and bottom parts 300B and 300C, respectively, to reach points adjacent the microphones on the mobile device when received within the case 300.

[0066] The visual data protection system includes a shutter element 122A located on the back side of the top part 300B of the case and shown in its first open position 122A1 uncovering the camera system on the back of the mobile device.
