The above described features and advantages of the invention will be apparent from the following description.

FIG. 1 is a schematic diagram of a sensing storage device, a first electronic device, and a second electronic device according to an embodiment of the invention. Referring to FIG. 1 , the sensing storage device 10 includes a connection interface circuit 101 , a microprocessor 102 , a smart card chip 103 , a fingerprint sensor 104 , and a touch panel 105 . The electronic device 11 (also referred to as a first electronic device) includes a connection interface circuit 111 and a processor 112. In addition, the electronic device 12 (also referred to as a second electronic device) includes a connection interface circuit 121 and a processor 122.

The connection interface circuit 101 is used to connect the sensing storage device 10 to the electronic device 11 or 12. The connection interface circuit 111 is used to connect the electronic device 11 to the sensing storage device 10. The connection interface circuit 121 is used to connect the electronic device 12 to the sensing storage device 10. However, it should be noted that at one point in time, the connection interface circuit 101 can only be connected to one of the connection interface circuits 111 and 121.

In the present embodiment, the connection interface circuits 101, 111, and 121 respectively include a plurality of pins. After the connection interface circuit 101 is connected to the connection interface circuit 111 and the connection is established, the sensing storage device 10 and the electronic device 11 can communicate with each other and transfer data via pins that are mutually matched (ie, electrically connected to each other). In addition, after the connection interface circuit 101 is connected to the connection interface circuit 112 and the connection is established, the sensing storage device 10 and the electronic device 12 can communicate with each other and transfer data via pins that are mutually matched (ie, electrically connected to each other).

The microprocessor 102 is connected to the connection interface circuit 101, the smart card chip 103, the fingerprint sensor 104, and the touch panel 105, and is used to control the overall operation of the sensing storage device 10. For example, microprocessor 102 can be a circuit module or microprocessor chip that is comprised of multiple control circuits. In addition, the processors 112 and 122 may also be a central processing unit (CPU) or a circuit module or a processing chip composed of a plurality of control circuits, respectively.

The smart card chip 103 stores card data and supports access to the card material. In the present embodiment, the smart card chip 103 is a contact smart card chip conforming to the ISO/IEC 7816 standard. However, in another embodiment, the smart card chip 103 may also be a contactless smart card chip or other type of smart card chip conforming to the ISO/IEC 1443 standard.

The fingerprint sensor 104 is used to sense a fingerprint and generate fingerprint data. For example, when a user's finger appears within the sensing area of fingerprint sensor 104, fingerprint sensor 104 can sense the fingerprint of the finger and generate relevant fingerprint data. This fingerprint data reflects the texture of the fingerprint of the user's finger. Additionally, fingerprint sensor 104 can include at least one fingerprint sensing element such as a sensing electrode or optical sensor.

The touch panel 105 is used to sense an input tool and generate touch data. For example, when an input tool such as a user's finger or a stylus appears in the sensing area of the touch panel 105, the touch panel 105 senses the input tool and generates related touch data. This touch data will reflect which position on the touch panel 105 the input tool is currently located on. In addition, the touch panel 105 can be a touch panel of a resistive touch panel, a capacitive touch panel, an optical touch panel, or a pressure sensing touch panel, and the present invention is not limited thereto.

In this embodiment, when the connection interface circuit 101 is not connected to the electronic devices 11 and 12, the smart card chip 103, the fingerprint sensor 104, and the touch panel 105 are all in an disabled state. When the smart card chip 103 is in the disabled state, the smart card chip 103 does not store or read data. When the fingerprint sensor 104 is in the disabled state, the fingerprint sensor 104 does not perform fingerprint sensing and does not generate fingerprint data. In addition, when the touch panel 105 is in the disabled state, the touch panel 105 does not perform touch sensing and does not generate touch data.

When the connection interface circuit 101 is connected to the electronic device 11 via the connection interface circuit 111, the microprocessor 102 enables the fingerprint sensor 104 and the touch panel 105. The enabled fingerprint sensor 104 can be used to sense fingerprints and generate fingerprint data. The enabled touch panel 105 can be used to sense an input tool and generate touch data. On the other hand, when the connection interface circuit 101 is connected to the electronic device 11 via the connection interface circuit 111, the microprocessor 102 maintains the smart card chip 103 in the disabled state.

When the connection interface circuit 101 is connected to the electronic device 12 via the connection interface circuit 121, the microprocessor 102 enables the fingerprint sensor 104 and the smart card chip 103. The enabled fingerprint sensor 104 can be used to sense fingerprints and generate fingerprint data. In addition, the enabled smart card chip 103 can be used to perform reading or storing of card data. On the other hand, when the connection interface circuit 101 is connected to the electronic device 12 via the connection interface circuit 121, the microprocessor 102 maintains the touch panel 105 in the disabled state.

In the embodiment, the electronic device 11 is a notebook computer, and the electronic device 12 is a smart card reader. However, in other embodiments not mentioned, the electronic device 11 and the electronic device 12 may also be other types of devices, respectively, as long as they comply with the relevant description herein.

2A and 2B are schematic diagrams showing the appearance of a sensing storage device according to an embodiment of the invention. Referring to Figures 2A and 2B, the sensing storage device 10 has a surface 201 (also referred to as a first surface) and 202 (also referred to as a second surface). Surfaces 201 and 202 are opposite. In one embodiment, surface 201 may also be referred to as the front side of sensing storage device 10, and surface 202 may also be referred to as the back side of sensing storage device 10.

When the fingerprint sensor 104 is enabled, the sensing range of the enabled fingerprint sensor 104 encompasses the area 21 (also referred to as the first area) of the surface 201. When the touch panel 105 is enabled, the sensing range of the enabled touch panel 105 encompasses the area 22 (also referred to as the second area) of the surface 201. The regions 21 and 22 do not overlap, and the area of the region 22 is larger than the area of the region 21. In an embodiment, the area 21 can also be regarded as a setting area of the fingerprint sensor (for example, the fingerprint sensor 104 of FIG. 1) in the storage device 10, and/or the area 22 can also be regarded as a sensing storage. A setting area of a touch panel (for example, the touch panel 105) in the device 10.

In addition, interface circuits 23 and 24 are disposed on surface 202. The interface circuits 23 and 24 belong to the connection interface circuit of the sensing storage device 10 (for example, the connection interface circuit 101 of FIG. 1). For example, the interface circuit 23 includes the pins of the connection interface circuit 101 of FIG. 1 that are connected to the smart card chip 103, and the interface circuit 24 includes the remaining pins of the connection interface circuit 101.

3A and 3B are schematic diagrams showing the appearance of a sensing storage device and a first electronic device according to an embodiment of the invention. Referring to FIGS. 3A and 3B, the electronic device 11 has a recess 31. The shape and depth of the groove 31 are respectively the same as or similar to the shape and height of the sensing storage device 10. The sensing storage device 10 is adapted to be removably placed within the recess 31 such that a connection interface circuit (eg, the connection interface circuit 101 of FIG. 1) of the sensing storage device 10 is coupled to the electronic device 11.

In the present embodiment, an interface circuit 32 is disposed in the recess 31. The interface circuit 32 belongs to a connection interface circuit of the electronic device 11 (for example, the connection interface circuit 111 of FIG. 1). When the sensing storage device 10 is placed in the recess 31, the interface circuit 32 is electrically connected to the interface circuit (eg, the interface circuit 24 of FIG. 2) that senses the back of the storage device 10. Moreover, when the sensing storage device 10 is placed in the recess 31, the front side of the sensing storage device 10 (eg, the surface 201 of FIG. 2) may be exposed outside the electronic device 11 while sensing the back side of the storage device 10 (eg, The surface 202) of FIG. 2 is then obscured by the electronic device 11.

In the present embodiment, after the sensing storage device 10 is placed in the recess 31, the regions 21 and 21 are simultaneously enabled. It should be noted that the area 21 is enabled to be equivalent to the fingerprint sensor of the sensing storage device 10 being enabled, and the area 22 is enabled to be equivalent to the touch panel of the sensing storage device 10 being enabled. The user can place their finger in contact or non-contact in the enabled area 21. At this time, the fingerprint data of the user is generated and transmitted to the electronic device 11 via the interface circuit 32. The processor of the electronic device 11 (e.g., the processor 112 of FIG. 1) can perform user identity verification based on fingerprint data from the sensing storage device 10. The verification result of the identity verification can be used for various operations such as login of the electronic device 11, unlocking of the electronic device 11, online shopping, webpage login or application login, etc., which must be verified by identity verification. Furthermore, depending on the input tool that is in contact or non-contacting action on the enabled region 22, corresponding touch data can also be generated and transmitted to the electronic device 11 via the interface circuit 32. The processor of the electronic device 11 (for example, the processor 112 of FIG. 1) can perform various types of control signal input operations such as screen cursor control or object selection control based on the touch data from the sensing storage device 10.

In an embodiment, after the sensing storage device 10 is placed in the recess 31, only the area 21 will be enabled first, and the area 22 will be maintained in the disabled state (equivalent to the touch of the sensing storage device 10). The control panel is maintained in the disabled state). The area 22 is enabled after the fingerprint data is transmitted to the electronic device 11 and the processor of the electronic device 11 (e.g., the processor 112 of FIG. 1) determines that the fingerprint data meets the preset condition. Taking FIG. 1 as an example, after receiving the fingerprint data from the sensing storage device 10, the processor 112 compares the fingerprint data with a preset fingerprint data. The preset fingerprint data is stored in the electronic device 10 and can be used to verify the identity of the user. If the similarity between the fingerprint data and the preset fingerprint data reaches a similarity threshold, the processor 112 determines that the fingerprint data meets the preset condition. On the other hand, if the similarity between the fingerprint data and the preset fingerprint data does not reach the similarity threshold, the processor 112 determines that the fingerprint data does not meet the preset condition. If the fingerprint data meets the preset condition, the processor 112 transmits an acknowledgement message to the microprocessor 102. The microprocessor 102 will enable the touch panel 105 based on this confirmation message. However, if the fingerprint data does not meet the preset condition, the processor 112 does not transmit the confirmation message, so that the touch panel 105 is continuously disabled.

In an embodiment, after the sensing storage device 10 is removed from the recess 31, the system state of the electronic device 11 is in a predetermined state (also referred to as a first state). After the sensing storage device 10 is placed in the recess 31, at least the area 21 will be enabled. After the processor of the electronic device 11 determines that the generated fingerprint data meets the preset condition, the system state of the electronic device 11 is switched from the first state to another preset state (also referred to as the second state). However, if the fingerprint data does not meet the preset condition, the system state of the electronic device 11 is maintained in the first state.

In an embodiment, the first state is a locked state and the second state is an unlocked state (or a normal operating state). In the locked state, the screen of the electronic device 11 may display a preset screen (for example, a lock screen or a login screen). Unless this locked state is released, the electronic device 11 will not be able to be further operated. For example, after the fingerprint data input by the user via the sensing storage device 10 is verified (for example, the fingerprint data meets a preset condition), in the unlocked state, the preset screen can be switched to the homepage of the electronic device 11 Or a desktop, and the user can perform operations such as sliding or clicking in the area 22 to operate the electronic device 11.

In an embodiment, once the sensing storage device 10 is inserted into the recess 31 such that the sensing storage device 10 is connected to the electronic device 11, the system state of the electronic device 11 is switched from the first state to the second state without The fingerprint verification described above needs to be performed to switch the system state of the electronic device 11.

In an embodiment, the sensing storage device 10 itself also stores a device verification code. For example, the device verification code can be stored non-volatilely in the microprocessor 102 of FIG. After the sensing storage device 10 is inserted into the recess 31, the sensing storage device 10 also transmits the device verification code to the electronic device 11 via the connection interface 32. The processor of the electronic device 11 can also decide whether to switch the system state of the electronic device 11 according to the device verification code. Taking FIG. 1 as an example, the processor 112 can determine whether the device verification code currently from the sensing storage device 10 is the same as a preset verification code. If the device verification code is the same as the preset verification code, it indicates that the currently inserted sensing storage device 10 is authenticated. Accordingly, the processor 112 can switch the system state of the electronic device 11 from the first state to the second state. On the other hand, if the device verification code is different from the preset verification code, it indicates that the currently inserted sensing storage device 10 is not an authenticated device. Therefore, the processor 112 maintains the system state of the electronic device 11 in the first state, preventing the electronic device 11 from being stolen. In an embodiment, the device verification code and fingerprint data may be used as a double verification for the user identity of the sensing storage device 10. For example, the system state of the switching electronic device 11 is allowed to be the second state only when both the device verification code and the fingerprint data pass the verification.

In an embodiment, the electronic device 11 also has a switching element 33. The switching element 33 is used to physically lock or release the sensing storage device 10. For example, when the sensing storage device 10 is to be placed in the recess 31, the user can move the switching element 33 so that the sensing storage device 10 can be placed smoothly. After the sensing storage device 10 is placed in the recess 31, the user can release the switching element 33 such that the sensing storage device 10 is caught by the cassette controlled by the switching element 33 in the recess 31. Thereafter, when the sensing storage device 10 is to be removed from the recess 31, the user can move the switching element 33 again so that the sensing storage device 10 can be smoothly removed. It should be noted that the present invention does not limit the position and type of the switching element 33 on the electronic device 11, as long as the sensing storage device 10 can be physically controlled to lock or release.

It should be noted that, in the above embodiment, after the sensing storage device 10 is connected to the electronic device 11, the operations such as identity verification, device verification, and control signal input are not involved in the sensing storage device 10. An enabled smart card chip (eg, smart card chip 103 of Figure 1).

FIG. 4 is a schematic diagram of the appearance of a sensing storage device and a second electronic device according to an embodiment of the invention. Referring to FIG. 4, the sensing storage device 10 can be inserted into the electronic device 12 (ie, the second electronic device). After the sensing storage device 10 is inserted into the electronic device 12, the sensing storage device 10 is connected to the electronic device 12 (eg, the connection interface circuit 101 of FIG. 1 is connected to the connection interface circuit 121), and the area 21 is enabled. . Then, the sensing storage device 10 can sense the fingerprint of the user via the area 21 and generate corresponding fingerprint data.

In an embodiment, after the sensing storage device 10 is inserted into the electronic device 12, the processor of the electronic device 12 receives the fingerprint data and the smart card identity data from the sensing storage device 10. The fingerprint data is generated by the fingerprint sensor of the sensing storage device 10 sensing the fingerprint of the user via the area 21, and the smart card identity data is provided by the smart card chip of the sensing storage device 10. For example, the smart card identity data is stored in the smart card wafer 103 of FIG. If the processor of the electronic device 12 determines that the fingerprint data matches the smart card identity data, the processor of the electronic device 12 receives the card data provided by the smart card chip from the sensing storage device 10 and performs a preset operation. Taking FIG. 1 as an example, the processor 122 compares the fingerprint data and the smart card identity data from the sensing storage device 10. If the similarity between the fingerprint data and the smart card identity data reaches a similarity threshold, the processor 112 determines that the fingerprint data matches the smart card identity data. On the other hand, if the similarity between the fingerprint data and the smart card identity data does not reach the similarity threshold, the processor 112 determines that the fingerprint data does not match the smart card identity data.

In other words, after the sensing storage device 10 is inserted into the electronic device 12, the electronic device 12 first performs identity verification involving the smart card chip in the sensing storage device 10 based on the fingerprint data from the sensing storage device 10. If the verification is passed, the electronic device 12 will start to access the smart card chip of the sensing storage device 10 to perform operations supported by various smart card chips such as card data inquiry, withdrawal, transfer or online deduction. If the verification is not passed, it indicates that the current sensing storage device 10 may have been stolen. Therefore, the electronic device 12 will not allow access to the smart card chip of the sensing storage device 10 (eg, not reading card data from the smart card wafer of the sensing storage device 10, nor writing data to the sensing storage device) 10 smart card chips).

In an embodiment, the identity verification of the smart card chip in the sensing storage device 10 may also be performed by the sensing storage device 10 itself without being executed by the electronic device 12. Taking FIG. 1 as an example, in an embodiment, after the connection interface circuit 101 is connected to the connection interface circuit 121, the microprocessor 102 reads the smart card identity data from the smart card chip 103. At the same time, the microprocessor 102 receives the fingerprint data from the fingerprint sensor 104 and compares the fingerprint data with the smart card identity data. If the fingerprint data matches the smart card identity data, the microprocessor 102 allows the electronic device 12 to access the card data of the smart card chip 103. For example, the microprocessor 102 can instruct the card material stored by the smart card wafer 103 to be transmitted to the electronic device 12. However, if the fingerprint data does not match the smart card identity data, the microprocessor 102 does not allow the electronic device 12 to access the card data of the smart card chip 103.

It should be noted that, in the above embodiment, after the sensing storage device 10 is connected to the electronic device 12, the performed identity verification does not involve sensing the touch panel that is not enabled in the storage device 10 (for example, The touch panel 105 of FIG. 1).

Referring back to FIG. 1, in an embodiment, the pins in the connection interface circuit 101 of the sensing storage device 10 include a first type of pins and a second type of pins. The first type of pins are used to transmit signals related to the operation of the smart card chip 103 and the touch panel 105, and the second type of pins are used to transmit signals related to the operation of the fingerprint sensor 104. For example, Table 1 below is a description of the functions of the pins and pins in the connection interface circuit 101 in an embodiment.

Pin. For example, the pin numbered 3 or 6 can be used to transfer the card data of the smart card chip 103 between the sensing storage device 10 and the electronic device 12, or to transfer the touch between the sensing storage device 10 and the electronic device 11. The touch data generated by the panel 105. In addition, numbers 10 and 11 can be used to transfer fingerprint data generated by the fingerprint sensor 104 between the sensing storage device 10 and the electronic device 11 (or 12).

It should be noted that the above Table 1 is only an example of at least a part of the pins in the connection interface circuit 101 in an embodiment.

If the electronic device 11 is connected to the sensing storage device 10, in step S603, it is determined whether or not fingerprint verification is performed. If fingerprint verification is to be performed, fingerprint data is received from the sensing storage device 10 in step S604.

In step S607, it is determined whether the inductive storage device 10 is removed. If the inductive storage device 10 is not removed, step S607 is repeatedly performed. If the inductive storage device 10 has been removed, the process proceeds to step S602.
