It is not necessarily the true proportion and precise configuration after the implementation of the creation. Therefore, the proportions and configuration relationships of the attached drawings should not be interpreted or limited in the actual implementation scope.

The advantages, features, and technical methods of the present invention will be more readily understood by referring to the exemplary embodiments and the accompanying drawings, and the present invention can be implemented in various forms and should not be construed as being limited to The stated embodiments, to the contrary, the embodiments of the present invention will provide a more thorough and complete and complete disclosure of the scope of the present invention, and the present invention will only be attached. The scope of the patent application is defined.

First, please refer to FIG. 1 and FIG. 2, which is a trigger provided by the present creative embodiment. The functional block diagram of the portable storage device with anti-stress function, and FIG. 2 is a schematic diagram of the application of the portable storage device for initiating the anti-stress function provided by the present embodiment.

In FIG. 1 , the portable storage device 1 mainly includes a first storage unit 11 , a second storage unit 12 , a fingerprint sensor 13 , and a control unit 14 . The first storage unit 11 is configured to store at least one digital data D that needs to be protected, and the first storage unit 11 can be, for example, a solid state hard disk or a flash memory, but this creation does not limit. In addition, the digital data D includes image data, video data or sound data, etc. In summary, the present creation is not limited thereto.

The second storage unit 12 is configured to store fingerprint information having a first preset group 120. However, for convenience of explanation, FIG. 1 only shows that the first preset group 120 contains one fingerprint information 120a. In other embodiments, the first preset group 120 may also include a plurality of fingerprint information. In addition, in the embodiment, the second storage unit 12 is independent of the first storage unit 11. In some embodiments, the second storage unit 12 can also be integrated with the first storage unit 11 into a single storage unit. In general, the present invention is not limited thereto.

The fingerprint sensor 13 acquires the fingerprint information 130a associated with a user in response to a touch event. The control unit 14 is coupled between the first storage unit 11, the second storage unit 12 and the fingerprint sensor 13, and when receiving the fingerprint information 130a of the user, the control unit 14 will be used to compare the user. Whether the fingerprint information 130a meets the fingerprint information 120a of the first preset group 120.

If yes, the control unit 14 allows the user to perform an access action on the first storage unit 11, and simultaneously triggers a counter-stress unit 15 to perform the anti-stress function in a background processing manner. The control unit 14 can be, for example, a microcontroller, but the present invention is not limited thereto.

In this embodiment, a preferred case is that the anti-stress unit 15 can be commonly configured in the portable storage device 1, but in some embodiments, the anti-stress unit 15 can also be configured to be In addition to the portable storage device 1, in general, the present creation is not limited thereto. Therefore, if the anti-stress unit 15 is first configured In the case of the portable storage device 1 as an example, when the portable storage device 1 is, for example, a portable disk, as shown in FIG. 2, the first storage unit 11, the second storage unit 12, and the control unit 14 and the counter-stress unit 15 can all be placed in a housing 10 of the flash drive. In addition, since the fingerprint sensor 13 can be implemented via a capacitive touch sensor, the fingerprint sensor 13 can be designed to be exposed outside the housing 10 of the flash drive. In this way, the fingerprint sensor 13 can be easily obtained by the fingerprint sensor 13 to obtain the fingerprint information 130a when the user performs a touch event.

In addition, according to the above, the portable storage device 1 further includes a first port 16 . The first port 16 is also exposed outside the housing 10 of the flash drive and is connected to a second port 20 on a host 2 (eg, a personal computer) to enable the first storage. The digital data D in the unit 11 can be transmitted to the host 2 through the first and the second ports 16, 20, or the other digital data stored in the host 2 can pass through the second The first port 20, 16 is transferred to the first storage unit 11 of the portable storage device 1.

It is worth mentioning that, regarding the overall appearance structure of the portable storage device 1, the present invention is not limited to the one shown in FIG. 2, so those having ordinary knowledge in the technical field should be able to perform according to actual needs or applications. The overall appearance of the portable storage device 1 is designed. In addition, in this embodiment, the first port 16 can select a connection port of the USB interface or other common interface port according to the requirement, and the second port 20 on the host 2 is also a USB interface.埠 or other common interface connections, in summary, this creation is not limited.

Further, it is assumed that the fingerprint information 120a having the first preset group 120 has been stored in the second storage unit 12 (for example, it is assumed that the fingerprint information 120a of the first preset group 120 can be represented as the use. Fingerprint information of the index finger of the person), the user can press the fingerprint sensor on the housing 10 by the index finger before the user is forced to read the protected digital data D by the gangster's coercion. 13,俾 The fingerprint sensor 13 is caused to obtain fingerprint information (ie, fingerprint information 130a) associated with the index finger of the user in response to the touch event. Then, upon receiving the fingerprint information 130a, the control unit 14 in the portable storage device 1 starts to determine whether the fingerprint information 130a meets the fingerprint information 120a of the first preset group 120.

However, since the fingerprint information 130a conforms to the fingerprint information 120a of the first preset group 120, the control unit 14 can determine that the user is currently in a "coerced state", and at this time, in order to preserve the The user's personal safety, so the portable storage device 1 of the present invention will still allow the user to access the first storage unit 11, but at the same time the control unit 14 in the portable storage device 1 will The triggering anti-stress unit 15 performs the anti-stress function in a background processing manner.

It should be noted that the above-mentioned "anti-stress function" may refer to an alarm function or any protection that can be beneficial to the safety of the user and the digital data D in the portable storage device 1. Measures, in summary, this creation does not limit the specific implementation of the anti-stress function, so those with ordinary knowledge in the technical field should be able to design according to actual needs or applications.

It should also be noted that the above-mentioned "execution of the anti-stress function by means of background processing" means that the above-mentioned so-called alarm function or any protection measure is performed without being perceived by the culprits. In this way, when the user is subjected to coercion, the related alarm function and protection measure can be performed at the same time, thereby effectively ensuring the personal safety of the user.

On the other hand, if the conventional principle of the fingerprint sensor 13 is considered to achieve the effect of data confidentiality, when such a design also extends to the portable storage device 1 of the present embodiment, it has Generally, the knowledgeable person should understand that the second storage unit 12 can further store the fingerprint information 121a of the second preset group 121, and when receiving the fingerprint information 130a of the user, the control unit 14 will also compare. Whether the fingerprint information 130a of the user matches the fingerprint information 121a of the second preset group 121.

If yes, the control unit 14 will allow the user to perform an access action on the first storage unit 11, but will not trigger the anti-stress unit 15 to perform the anti-stress function in the background processing manner. It is worth mentioning that, for the sake of convenience of description, FIG. 1 only shows that the second preset group 121 includes one fingerprint information 121a. However, in some embodiments, the first preset group 121 may also include a plurality of fingerprint information.

Further, if the fingerprint information 121a of the second preset group 121 is represented as the fingerprint information of the thumb of the user, when the user wants to normally access the digits in the first storage unit 11 In case of the data D, the user must touch the thumb of the fingerprint sensor 13 on the housing 10, so that the fingerprint sensor 13 can obtain the fingerprint information associated with the thumb of the user (also That is, the fingerprint information 130a). Then, since the control unit 14 finds that the fingerprint information 130a meets the fingerprint information 121a of the second preset group 121, the control unit 14 can determine that the user is currently in a "normal use". The portable storage device 1 of the present invention will allow the user to perform an access action on the first storage unit 11, but will not trigger the anti-stress unit 15 to perform the anti-stress function. In this way, it is possible to effectively prevent the intentional person from stealing the main information and to achieve the effect of confidentiality of the data.

Similarly, it should be understood that, if the control unit 14 starts to match whether the fingerprint information 130a meets the fingerprint information 120a, 121a of the first or second preset group 120, 121, if the fingerprint of the user When the information 130a does not meet the fingerprint information 120a, 121a of the first and second preset groups 120, 121, the control unit 14 can prohibit the user from performing an access action on the first storage unit 11, and does not trigger the reverse The duress unit 15 performs the anti-stress function in a background processing manner. However, since the above content is a conventional unlocking principle of the fingerprint recognition function, the details of the details thereof will not be further described herein.

In operation, since the second storage unit 12 does not initially store any fingerprint information, when the second storage unit 12 is to be registered with the first and second preset groups When the fingerprint information 120a, 121a of the 120, 121 is 120, 121, or when the second storage unit 12 is to update the fingerprint information 120a, 121a of the stored first and second preset groups 120, 121 again, It must be verified by additional administrators, and the registration and update of fingerprint information can only be carried out after the administrator has passed the verification. In this way, the fingerprint information of the non-legitimate user can be prevented from being registered and updated to the second storage unit 12, so as to avoid a more serious security vulnerability.

Therefore, the second storage unit 12 can further store the fingerprint information 122a of the third preset group 122, and when receiving the fingerprint information 130a of the user, the control unit 14 also compares the fingerprint information 130a with the fingerprint information 130a. The fingerprint information 122a of the third preset group 122.

If yes, the control unit 14 allows the user to perform an access operation on the first storage unit 11 and simultaneously provides a manager interface (not shown) to the user to selectively access the second storage unit 12 The fingerprint information 120a-122a of the first, second, and/or third preset groups 120-122 in the middle is registered and updated.

It is worth mentioning that, for the same convenience of explanation, FIG. 1 only shows that the third preset group 122 includes one fingerprint information 122a. However, in some embodiments, the third preset group 122 may also include a plurality of fingerprint information. In contrast, if the fingerprint information 130a of the user does not meet the fingerprint information 122a of the third preset group 122, the control unit 14 prohibits the user from performing an access operation on the first storage unit 11, and The triggering anti-stress unit 15 performs the anti-stress function in a background processing manner.

Further, it is assumed that the fingerprint information 122a of the third preset group 122 is represented as the fingerprint information of the thumb of a certain manager, and therefore only when the user needs to be equal to the manager, and The thumb has a fingerprint sensor 13 on the housing 10 to enable the control unit 14 to allow the user to perform normal use of the portable storage device 1 and thereby provide a manager interface to the user. Optionally registering and updating all fingerprint information in the second storage unit 12.

It should be noted that the so-called "providing the administrator interface to register and update the fingerprint information 120a-122a of the first, second, and/or third preset groups 120-122" may refer to the host. 2 has an application preset, and when the portable storage device 1 is connected to the host 2, the host 2 commands the fingerprint sensor 13 on the portable storage device 1 to start acquiring the first, The fingerprint information 120a-122a of the second and/or third preset groups 120-122 is used to register and update the fingerprint information 120a-122a in the second storage unit 12.

Alternatively, in other embodiments, the fingerprint sensor 13 can be triggered by a button (not shown) or other tool on the portable storage device 1 to start acquiring the first, second, and And the fingerprint information 120a~122a of the third preset group 120~122, and the registration and update of the fingerprint information 120a~122a in the second storage unit 12, without the command of the host 2. In summary, this creation does not limit the specific implementation of the administrator interface for registering and updating fingerprint information. Therefore, those skilled in the art should be able to design according to actual needs or applications.

On the other hand, the implementation of the triggering anti-stress unit 15 of the present creation when performing the anti-stress function will be further described below. However, it should be understood that the inventive concept may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to FIG. 1 and FIG. 2, in the present embodiment, a preferred case is that the anti-stress unit 15 includes a wireless transmitter 151. The wireless transmitter 151 is disposed in the portable storage device 1 and is configured to wirelessly transmit an alarm signal TS to the portable storage device when performing the anti-stress function. As shown in FIG. 2, a mobile communication device 3 and/or a cloud server 4 other than the device 1 is configured to enable the mobile communication device 3 and/or the cloud server 4 to execute according to the alarm signal TS. Corresponding to an alarm function.

Specifically, the wireless transmitter 151 can be, for example, a Wi-Fi transmitter or a Bluetooth transmitter, but the present invention is not limited thereto. Therefore, in practice, this wireless transmission The transmitter 151 cannot perform the alarm function directly through the conventional GSM dialing method. Therefore, the so-called "triggering anti-stress unit 15 performs the anti-stress function in the background processing manner", that is, the definition is to trigger the wireless transmitter 151 to transmit the alarm signal TS to the portable type by way of wireless. The mobile communication device 3 and/or the cloud server 4 outside the storage device 1 and the mobile communication device 3 and/or the cloud server 4 are dialed to the police or dialed to the preset at least according to the alarm signal TS. A phone number.

On the other hand, in the mobile communication device 3 and the cloud server 4 of the present embodiment, an application program is preset, so that after receiving the alarm signal TS from the wireless transmitter 151, the action is performed. The communication device 3 and the cloud server 4 can perform the associated alarm function according to the alarm signal TS.

It should be noted that the above-mentioned "alarm signal TS" may refer to a message for notifying that "the user is currently in a state of being coerced", but the present invention is not limited thereto. In summary, this creation does not limit the specific implementation of the alarm signal TS. In the same way, the present invention does not limit the specific implementation manner when the mobile communication device 3 and the cloud server 4 perform the alarm function. Therefore, those skilled in the art should be able to design according to actual needs or applications.

It is worth mentioning that, in this embodiment, a preferred case is that the mobile communication device 3 is a smart phone held by the user, as shown in FIG. 2 . Therefore, the mobile communication device 3 should have a built-in recording module (not shown) and a GPS positioning module (not shown). Therefore, in practice, when the wireless transmitter 151 is triggered to perform the anti-coercion function, the wireless transmitter 151 can further transmit the at least one additional signal BS to the mobile communication device 3 in a wireless manner, so as to enable the action. The communication device 3 is configured to perform a corresponding recording function and/or a GPS positioning function according to the additional signal BS. However, since the recording function and the GPS positioning function that can be performed on the mobile communication device 3 are well known to those of ordinary skill in the art, the details thereof will not be further described herein.

It should be noted that when the mobile communication device 3 is held by the user In the case of a smart phone, the mobile communication device 3 should be dialed to the police or at least one preset phone number in the same background (for example, silent or black screen), or the same The background processing method performs the recording and the function of the GPS positioning. In this way, we can truly ensure that the personal safety of the user is protected without being perceived by the culprits.

However, in the above manner, the digital data D in the first storage unit 11 is still often in a state of being easily stolen, and therefore, in some embodiments, the anti-stress unit 15 further includes a destroyer 153. The destroyer 153 is also disposed in the portable storage device 1 , and the destroyer 153 is configured to destroy the digital data in the first storage unit 11 by using background processing when performing the anti-stress function. D.

For example, in practice, the destroyer 153 can be implemented via a current switch, so when the anti-stress function is designed, the current switch will increase the amount of current passing through the first storage unit 11 and thereby destroy it. This first storage unit 11 is dropped. In this way, the user can actively destroy the first storage unit 11 without being perceived by the gangster, so as to ensure that the confidential information therein will not flow out at all. It should be noted that the implementations of the above-mentioned destroyer 153 are merely examples, which are not intended to limit the creation. Therefore, those skilled in the art should be able to perform the destroyer 153 according to actual needs or applications. the design of.

On the other hand, as described in the foregoing, the counter-stress unit 15 is not limited to being able to be configured only in the portable storage device 1, and therefore the following will be directed to the triggering anti-stress unit 15 of the present creation to perform the anti-stress function. Another implementation is further described. Please refer to FIG. 3 and FIG. 4 together. FIG. 3 is a functional block diagram of a portable storage device for inducing anti-stress function according to another embodiment of the present invention, and FIG. 4 is a schematic diagram of another embodiment of the present invention. A schematic diagram of the application of a portable storage device that triggers a counter-stress function. The components in FIG. 3 and FIG. 4 which are the same as or similar to those in FIG. 1 and FIG. 2 are denoted by the same or similar reference numerals, and thus will not be further described herein.

In detail, the portable storage device 1' of FIG. 3 does not actively include the counter-stress unit 15 as compared to the portable storage device 1 of FIG. Conversely, the counter-stress unit 15 is included in the host 2. Therefore, the anti-stress unit 15 can mainly include a communicator 155, and the communicator 155 is disposed in the host 2. In general, the communicator 155 can be, for example, a wired/wireless network device or a GSM device built in the host 2, but the present invention is not limited thereto.

Furthermore, since the host 2 has been preset to have an application, and when the user has to read the digital data D, the host 2 will inevitably be used to communicate with the portable device via its second connection 20 The first ports 16 of the storage device 1' are connected. Therefore, when the control unit 14 of the portable storage device 1' determines that the user system is currently in a "intimidated use state" (that is, the fingerprint information 130a conforms to the fingerprint information of the first preset group 120). 120a), the control unit 14 of the portable storage device 1' will still allow the user to perform an access operation on the first storage unit 11, but at the same time, the control unit 14 will also pass through the first and second ports 16, 20 transmits a trigger command (not shown) to the communicator 155 of the host 2 to cause the communicator 155 to perform the corresponding alarm function according to the trigger command.

It should be noted that the present invention does not limit the specific implementation manner of the triggering instruction, and the present invention does not limit the specific implementation manner when the alarm function is performed by the communicator 155. Therefore, those having ordinary knowledge in the technical field should be able to Design or application to design. According to the above, the alarm method of FIG. 3 and FIG. 4 is changed to directly use the host 2 connected to the portable storage device 1' to perform the alarm method as compared with the alarm method illustrated in FIG. 1 and FIG. . Therefore, the portable storage device 1 ′ of the present embodiment will not only need to rely on complicated external devices (for example, the mobile communication device 3 and the cloud server 4 of FIG. 2 ) to perform an alarm function, and the portable storage device The device 1' also has the advantage of being small in size and simple in design.

It should be understood that when the host 2 is performing an alarm function, the communicator 155 should dial to the police or the preset at least one telephone number in the same background processing manner (for example, silent manner). In this way, we can ensure that we are not being defamed. In case of perceptual awareness, to protect the personal safety of the user. In addition, in this embodiment, the anti-stress unit 15 of the host 2 may also include various components having functions of performing recording and GPS positioning according to its requirements. In general, the present invention is not limited thereto. In addition, the specific implementations described above are merely used for exemplification, and are not intended to limit the present invention. Therefore, those skilled in the art should be able to design according to actual needs or applications.

In summary, the portable storage device provided by the creation of the anti-stress function not only can successfully achieve the effect of data confidentiality, but also allows the user to perform relevant correlations at the same time when subjected to coercion. The alarm function and protection measures are used to effectively protect the personal safety of the user.

The embodiments described above are only for explaining the technical idea and characteristics of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement them according to the scope of the patent. That is, the equivalent changes or modifications made by the people in accordance with the spirit revealed by this creation should still be covered by the scope of the patent of this creation.
