DETAILED DESCRIPTION
Described herein is a technology for self-disabling feature of a wireless device to avoid unauthorized access to stored data information. More particularly, a method to protect the data information in a storage component such as static random access memory (SRAM), dynamic random access memory (DRAM), magneto resistive random access memory (MRAM) or a logic base memory is described.
In an implementation, the self-disabling feature of the wireless device includes a detecting mechanism, triggering mechanism, shut-off mechanism, and a storage mechanism. For example, the detecting mechanism may measure signals to determine if there is a deviation in a set of signals that defines a threshold for proper operations of the wireless device. For example, the detecting mechanism measures amount of radiation exposure of the wireless device or total resistance in a circuit of the wireless device. In this example, the measured signal is received and processed by the triggering mechanism.
The triggering mechanism is configured to provide a triggering signal based upon the measured signal in the detecting mechanism. For example, if the measured amount of radiation exposure exceeds a limit imposed by government regulations or if the measured total resistance signifies a physical removal of the storage component in the circuit of the wireless device, then the triggering mechanism provides the triggering signal to the shut-off mechanism. For example, the shut-off mechanism contains a high-surge voltage component to permanently cut-off electrical signals to the storage mechanism, or a micro electro mechanical system (MEMS) based hardware that is configured to temporarily lock down access to the storage component. In this example, the high-surge voltage or the MEMS based hardware may be enabled by the triggering signal.
FIG. 1 illustrates a scenario 100 that shows a wireless device with self-disabling features to avoid unauthorized access by a third party. As shown, scenario 100 depicts an owner 102 who is a true owner of a wireless device 104-2, and an unauthorized user 106. Furthermore, scenario 100 shows a network 108 that is utilized by the owner 102 to gain access to the wireless device 104-2 using another wireless device 104-4.
As shown, the owner 102 lost his wireless device 104-2 and that the unauthorized user 106 is now in possession of the wireless device 104-2. In this example, the owner 102 may have stored important data information (not shown) into the wireless device 104-2 before the unauthorized user 106 took possession of it. As such, the owner 102 plans to stop the unauthorized user 106 from retrieving any of the data information from the wireless device 104-2.
With continuing reference to FIG. 1, the owner 102 may utilize the wireless device 104-4 to send a remote triggering signal (not shown) through the network 108. The remote triggering signal may be a remote software triggering signal that is transmitted through the network 108 to disable any access to the data information of the wireless device 104-2. The remote triggering signal is received by the wireless device 104-2 and a self-disabling feature of the wireless device 104-2 is activated or enabled. For example, the wireless device 104-2 includes a shut-off mechanism (not shown) that cuts off electrical signal into the wireless device 104-2 when the shut-off mechanism is enabled or activated by the triggering signal.
In another example, a radio signal (not shown) such as a cellular signal, a wireless fidelity (Wi-Fi) signal, and the like, may be used by the user 102 to access the wireless device 104-2. For example, the user 102 may send the remote triggering signal through the cellular signal by sending an encrypted text messaging. In this example, the wireless device 104-2 enables its shut-off mechanism to deny access to the data information. In another example, the triggering signal may be derived from an error in biometric identification of the unauthorized user 104 or the triggering signal may be derived from multiple input password errors entered into by the unauthorized user 104. In this example, there is no need for the remote triggering signal to enable the disabling features of the wireless device 104-2; however, a local based hardware such a configured processor or a control unit within the wireless device 104-2 may provide a local triggering signal.
As depicted, the wireless device 104 may include, but not limited to, a mobile phone, a cellular phone, a smartphone, a personal digital assistant, a tablet computer, a netbook, a notebook computer, a laptop computer, a multimedia playback device, a digital music player, a digital video player, a navigational device, a digital camera, and the like.
FIG. 2 illustrates a block diagram 200 that implements the self-disabling feature of the wireless device 104. Block diagram 200 shows a detecting mechanism 202, a trigger mechanism 204, a shut-off mechanism 206, and a storage mechanism 208. In an implementation, these mechanisms (i.e., detecting mechanism 202, etc.) may be fabricated in a single module such as, for example, in a single IC device. In another implementation, the detecting mechanism 202, trigger mechanism 204, and the shut-off mechanism 206 may be external to the storage mechanism 208 that may be fabricated in the single module or IC device.
In a case where the wireless device 104 is lost, the wireless device 104 may have a different power and/or network connection status at the hand of the unauthorized user 106. For example, the wireless device 104 may have drained its power battery and so, it is powered OFF, or the wireless device 104 may be powered ON but not connected to any network or radio signal, or it may be powered ON and is connected to the network or radio signal.
For example, when the wireless device 104 is powered OFF, the detecting mechanism 202 may include a sensor (now shown) that is configured to measure and compare input signals to a set of signals in the wireless device 104. For example, when the unauthorized user 106 physically takes out an IC device (not shown) that is configured as the storage mechanism 208 in the wireless device 104, the sensor in the detecting mechanism 202 may measure a change in total resistance, capacitance, and the like, in the wireless device 104 (e.g., in a motherboard where the IC device is connected). In another example, the sensor may sense high frequency vibrations due to sawing or polishing of the IC device. In these examples, the sensor may compare the measured total resistance or the high frequency vibrations to the set of signals in the wireless device 104. The set of signals may contain threshold signals (e.g., standard resistance measurements, etc.) for ideal operations or status of the wireless device 104.
As illustrated, when the wireless device 104 is powered ON but not connected to any network or radio signals, the detecting mechanism 202 may measure the signals such as the signals due to different biometric identification signals, signals due to input password errors, or signals due to global positioning system (GPS) entry in the wireless device 104. In these examples, the detecting mechanism 202 may compare these signals to corresponding set of signals (i.e., threshold signals) that are configured in the wireless device 104. For example, when the unauthorized user 106 inputs his fingerprints to the wireless device 104, the detecting mechanism 202 may compare these fingerprints to the fingerprints of the owner 102 (i.e., threshold signals) that are stored in the wireless device 104. In another example, if the wireless device 104 is located in a place that is configured in the wireless device 104 to be the place or a zone for activating its disabling feature, then the detecting mechanism 202 detects signals from GPS features of the wireless device 104 and utilizes these signals in activating the disabling feature of the wireless device 104.
As illustrated, when the wireless device 104 is powered ON and is connected to the network or radio signals, the detecting mechanism 202 may be bypassed and the user 102 may directly enable the triggering mechanism 204 such as, for example, through the network or radio signals. For example, the wireless device 104 is configured with software that enables its self-disabling feature when receiving a remote triggering signal through the network or the radio signals. In this example, the remote triggering signal is directly processed at the trigger mechanism 204. In other words, in this example, the remote triggering signal bypasses operations in the detecting mechanism 202.
In an implementation, the shut-off mechanism 206 may be configured to electrically or mechanically cut-off electrical signals to the storage mechanism 208. The cutting-off of the electrical signals may be temporarily or permanently such as when the IC device is permanently damaged by a surging voltage (not shown) from the shut-off mechanism 206. For example, the shut-off mechanism 206 may supply a high surging voltage from a charged capacitor within the IC device or from a supply voltage across the motherboard in the wireless device 104 to permanently damage the IC device. In another example, the shut-off mechanism 206 may include a MEMS based hardware lock to temporarily cut-off the electrical signals that is utilized to access the storage mechanism 208.
In an implementation, the high surging voltage from the shut-off mechanism 206 may come from the charged capacitor or the supply voltage. The high surging voltage may contain a value (e.g., 5 Volts) that may be sufficient enough to permanently cut-off the electrical signals within the IC device. Typically, the IC device and more particularly the storage mechanism 208 is made up of multiple numbers of transistors (not shown). For proper transistor operations, a gate terminal of this transistor is coupled to an input control voltage Vin or a biasing voltage. In this case, the Vin switches between several predetermined control voltages. However, these control voltages are sized or configured so as not to cause any damage to PN junction of the transistor. As such, the high surging voltage from the shut-off mechanism 206 may be configured to supply a voltage that is above a threshold voltage (i.e., maximum voltage for proper operations) to permanently cut-off the electrical signals in the storage mechanism 208. In other words, the high surging voltage may cause irreversible damage to the PN junction of the transistor that acts as the storage mechanism 208.
In an implementation, the MEMS based hardware lock is a recordable locking device that contains series of tiny notched gears that mechanically move to an unlocked position only when the right code is entered. In the case where the unauthorized user 106 enters a wrong password, the MEMS based hardware lock may temporarily cut-off the electrical signals into the storage mechanism 208. In this example, access to data information in the wireless device 104 is mechanically disabled until the owner 102 resets the wireless device 104 with a proper password.
With continuing reference to FIG. 2, the block diagram 200 may be implemented to comply with export regulations such as chip needs to exhibit failure within a defined total ionizing dose (TID). This export regulation was put in place in the interest of national security. For example, common radiation induced effects may include: Bit Error Rate (BER), environment induced data errors referred to as Soft Error Rate (SER), failure in time (FIT), operating system or applications crashes are Detected Uncorrectable Error (DUE), or bad data written to disks known as Silent Data corruption, (SDC).
Although the IC device may be robust enough to withstand radiation that is above the defined TID for export regulation purposes, the block diagram 200 may similarly be implemented to disable access to the IC device. For example, the detector mechanism 202 utilizes a dosimeter (not shown) that is configured to measure amount of radiation. In this example, if the amount of radiation measured exceeds TID regulation limits regulation limits, then the trigger mechanism 204 may provide the triggering signal to the shut-off mechanism 206. To this end, the high-surging voltage from the shut-off mechanism 206 may cause irreversible damage to the storage mechanism 208.
FIG. 3 illustrates an example IC device 300 that implements the different mechanisms (e.g., detecting mechanism 202, etc.) of the self-disabling feature of the wireless device 104. The IC device 300 may be, for example, a processor or a component such as a storage component of the wireless device 104.
As shown, the IC device 300 may include a control unit 302, a remote trigger 304, a local software trigger 306, a local hardware trigger 308, an input peripheral trigger 312, a high-surge voltage 314, a MEMS based hardware 316, and static random access memory (SRAM)/dynamic random access memory (DRAM)/magneto-resistive random access memory (MRAM) 318.
In a case where the wireless device 104 is powered ON and is further connected to the network 108 or the radio signal, the remote software trigger 304 may process a received remote triggering signal through the network 108 or the radio signal. For example, when the owner 102 communicates a text message that is configured to activate the shut-off mechanism of the IC device 300, the remote trigger 304 may be configured to process the received text message and transmit a triggering signal to the shut-off mechanism of the IC device 300. In this example, the high-surge voltage 314 may supply a voltage that is above configured threshold voltage (i.e., maximum voltage of operations) of the IC device 300 or more particularly, the SRAM/DRAM/MRAM 318.
In a case where the wireless device 104 is powered ON but not connected to the network 108 or any radio signal, the local software trigger 306 may be configured to transmit the triggering signal to the shut-off mechanism of the IC device 300. For example, if the local software trigger 306 is configured to interpret a lack of activity in the wireless device 104 for the last twenty four hours as stolen wireless device 104, then the local software trigger 306 is configured to transmit the triggering signal to the shut-off mechanism if no activity is detected in the wireless device 104 within the last 24 hours.
In a case where the wireless device 104 is powered OFF, the local hardware trigger signal 308 may be configured to transmit the triggering signal to the shut-off mechanism of the IC device 300. For example, when the IC device 300 is taken out from the wireless device 104, the local hardware trigger signal 308 may be configured to detect this action through a sensor 310 (e.g., Ohm Meter for resistance measurements) and transmits the triggering signal to the shut-off mechanism of the IC device 300. Since there is no power in the wireless device 104 in this example, the charged capacitor may be utilized to deliver the voltage that is above the voltage threshold of the IC device 300.
In a case where the wireless device 104 is powered ON, the local hardware trigger signal 308 may be configured to transmit the triggering signal to the shut-off mechanism of the IC device 300. For example, the sensor 310 may be a dosimeter that measures amount of radiation to comply with TID regulation limits. In this example, upon reaching the TID regulation limits, the local hardware trigger signal 308 transmits the triggering signal to the shut-off mechanism of the IC device 300. The shut-off mechanism may then supply the high-surging voltage to destroy or disable access to the SRAM/DRAM/MRAM 318.
In a case where the wireless device 104 is powered ON but not connected to the network 108 or any radio signal, the input peripheral trigger 312 is configured to transmit the triggering signal to the shut-off mechanism of the IC device 300. For example, when multiple input password errors are detected from a keyboard input peripheral of the wireless device 104, the MEMS based hardware 316 may temporarily lock down the electrical signal that is utilized to access the SRAM/DRAM/MRAM 318. Other input peripherals of the wireless device 104 may include a sound/voice input peripheral, camera, and the like.
In an implementation, the high surge voltage 314 may permanently cut-off the electrical signals to the SRAM/DRAM/MRAM 318. For example, the SRAM/DRAM/MRAM 318 is composed of transistors. In this example, a surging voltage from the charged capacitor or a voltage supply (not shown) may cause an irreversible damage to the PN junction of the transistors that forms the SRAM/DRAM/MRAM 318. In a case where the local hardware trigger 308 is utilized when the wireless device 104 is powered OFF, the charged capacitor is utilized to supply the surging voltage since the voltage supply is zero due to power OFF condition of the wireless device 104.
FIG. 4 shows an example process flowchart 400 illustrating an example method of implementing the self-disabling feature of the wireless device 104. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method, or alternate method. Additionally, individual blocks may be deleted from the method without departing from the spirit and scope of the subject matter described herein. Furthermore, the method may be implemented in any suitable hardware, software, firmware, or a combination thereof, without departing from the scope of the invention.
At block 402, determining if a wireless device is powered ON. For example, if the wireless device (e.g., wireless device 104) is powered OFF, then following a NO signal at block 404, a local hardware trigger component (e.g., local hardware trigger 308) of an IC device (e.g., IC device 300) may be configured to generate a local hardware triggering signal based from signal measurements by a detecting mechanism (e.g., sensor 310) in the wireless device 104. For example, the sensor 310 may be an ohm meter that measures changes in total resistance in circuitry of the wireless device 104 if the IC device 300 is physically removed from the circuitry. In this example, the local hardware trigger 308 processes the change in total resistance and generates the local hardware triggering signal.
In another example, the sensor 310 is configured to detect high frequency vibrations due to sawing or polishing of the IC device 300. In this example, the local hardware trigger 308 processes the change in vibrations and generates the local hardware triggering signal.
At block 406, a voltage is supplied based on the received local hardware triggering signal. For example, if the received local hardware triggering signal indicates the change in total resistance in the circuitry of the wireless device 104, then a high-surge voltage component (e.g., high-surge voltage 314) may generate the voltage that is sufficient to cause irreversible damage to SRAM/DRAM/MRAM component (e.g., SRAM/DRAM/MRAM 318) at block 408. In this example, a charged capacitor may be configured to supply the voltage since the wireless device is powered OFF.
In a case where the sensor 310 is a dosimeter that measures radiation exposure of the IC device 300, the wireless device 104 may be at either powered OFF or powered ON state. For example, the dosimeter may be a transducer that measures the radiation even if the wireless device 104 is powered OFF. In this example, the charged capacitor may generate the voltage to cause irreversible damage to SRAM/DRAM/MRAM at block 408. On the other hand, if the wireless device 104 is powered ON, then a voltage supply may also generate the voltage to cause irreversible damage to SRAM/DRAM/MRAM at block 408.
With continuing reference to block 402, if the wireless device 104 is powered ON, then following a YES signal at block 410, a determination on whether the wireless device 104 is connected to a network is performed.
If the wireless device 104 is connected to the network (e.g., network 108), then following a YES signal at block 412, remote trigger component (e.g., remote trigger 304) is configured to generate a remote triggering signal based from received signals through the network 308 or other radio signals. For example, if an owner (e.g., owner 102) communicates a text message that is configured to enable a shut-off mechanism of the wireless device 104, then the remote trigger 304 may process the received text message and generates the remote triggering signal to the high-surge voltage 314 at block 414. Since the wireless device is powered ON, the high-surge voltage 314 may utilize the charged capacitor or a voltage supply to supply the voltage that permanently cuts-off the electrical signals in the SRAM/DRAM/MRAM at block 408.
With continuing reference to block 410, if the wireless device 104 is powered ON but not connected to the network 308, then a local software trigger (e.g., local software trigger 306) at block 416 may be configured to generate a local software triggering signal to enable the high-surge voltage at block 418 to permanently cut-off the electrical signals in the SRAM/DRAM/MRAM at block 408. For example, if the wireless device 104 is configured to enable its shut-off mechanism upon detection of lack of activity for a certain time (e.g., no activity in the wireless device for 24 hours), then the local software trigger 306 may receive and process this lack of activity signal and generates the local software triggering signal.
Back to block 402, when the wireless device 104 is powered ON, a determination at block 420 of whether a third-party is trying to access data information is performed. For example, if the third party (e.g., unauthorized user 106) is entering a biometric identification such as a fingerprint, then an input peripheral trigger component (e.g., input peripheral trigger 312) may be configured to detect accuracy of the fingerprint of the unauthorized user 106 and may generate an input peripheral triggering signal to enable a MEMS based hardware (e.g., MEMS based hardware 316) at block 422. For example, the MEMS based hardware at block 424 temporarily shuts-off the electrical signals that are utilized to access the SRAM/DRAM/MRAM at block 408. In a case where there is no third-party at block 420, then following the NO signal at block 410, the process at block 410 as discussed above may apply.
FIG. 5 shows an example process flowchart 400 illustrating an example method of manufacturing an IC device that implements self-disabling mechanism to avoid unauthorized access to data memory. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method, or alternate method. Additionally, individual blocks may be deleted from the method without departing from the spirit and scope of the subject matter described herein. Furthermore, the method may be implemented in any suitable hardware, software, firmware, or a combination thereof, without departing from the scope of the invention.
At block 502, building a control unit that is configured to provide triggering signals based upon a measured signal. For example, the control unit (e.g., control unit 302) may be configured to receive and process the measured signal that is supplied by a detector mechanism such, for example, a sensor (e.g., sensor 310). In this example, the control unit 302 is configured to transmit the triggering signals based from the measured signal. For example, the sensor 310 is configured to measure the signal that represents a password input from a user. In this example, the sensor is pre-configured to check if the password input is authorized or unauthorized. In another example, the sensor may measure total resistance in a circuitry of the IC device in a case where the IC device is taken out from the wireless device 104. In these examples, the control unit 302 may transmit the triggering signals based from the measured unauthorized password input signals or total resistance signals.
At block 504, installing a shut-off mechanism that is configured to cut-off electrical signal into the IC device. For example, the shut-off mechanism may utilize a high-surge voltage component (e.g., high-surge voltage 314) to supply the voltage that permanently cuts-off the electrical signals in the IC device 300 or storage component such as SRAM/DRAM/MRAM 318. In another example, the shut-off mechanism may utilize the MEMS hardware based switch to mechanically lock down temporarily the access to the storage component in the IC device 300. This locking down may be reset by owner 102 who is aware of reset password to unlock the wireless device 104.
At block 506, building the storage component that is coupled with the shut-off mechanism.
