Description

Technical Field

[0001] This utility model relates to the field of information security technology, and in particular to a wireless fingerprint mouse. Background Technology

[0002] With the rapid development of information technology, the trend towards informatization and networking has become inevitable across all industries. Based on this, various industries are undergoing digital transformation, integrating operations management and risk control with the Internet of Things, cloud computing, and big data to improve the level of intelligent operation. Against this backdrop, the application of fingerprint mice is becoming increasingly widespread, and users' demands for fingerprint mouse security are further increasing. The authentication method of the information system is a key factor determining the security performance of fingerprint mice.

[0003] In existing fingerprint mouse solutions, traditional authentication technologies largely rely on passwords composed of numbers and characters. However, traditional single-factor authentication is no longer sufficient to meet the needs of critical information systems due to security risks such as weak passwords and brute-force attacks. Furthermore, fingerprint chips typically employ a coating method, using ordinary paint for spraying or screen printing to achieve both aesthetic and surface protection against wear. However, ordinary paint only provides protection in terms of appearance and hardness, failing to guarantee that fingerprints will not remain on the paint surface. These residual fingerprint patterns can be easily reproduced through high-definition photography, leading to the leakage of personal information. Utility Model Content

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0030] Figure 1 This is a structural schematic diagram of a wireless fingerprint mouse according to an embodiment of the present utility model. Figure 1 As shown, the wireless fingerprint mouse includes: a mouse chip 100, a fingerprint sensor 110, a security chip 120, and a wireless transmitter 130. The mouse chip 100 is used for initial authentication of the target user; the fingerprint sensor 110 is used to acquire the target user's fingerprint information after the initial authentication is successful; the surface of the fingerprint sensor 110 is provided with an anti-fingerprint coating; the security chip 120 is connected to the fingerprint sensor 110, and is used to receive the target fingerprint information sent by the fingerprint sensor 110 and perform enhanced authentication of the target user based on the target fingerprint information; the wireless transmitter 130 is connected to the security chip 120 and also to the mouse chip 100; the wireless transmitter 130 is used to transmit the transmission data generated by the mouse chip 100 and the secure transmission data generated by the security chip 120 after the enhanced authentication of the target user is successful.

[0031] For example, the mouse chip 100 performs preliminary authentication of the target user, including: storing the username and password information sent to the target user; obtaining the target user's username and password information when the target user uses the wireless fingerprint mouse; and performing preliminary identity verification of the target user based on the username and password information. For example, the username and password information is obtained through mouse management software, where an initial password is set, which is the username and password information. If the password entered by the user does not match the initial password, the fingerprint sensor 110 will not collect the target fingerprint information.

[0032] The fingerprint sensor 110 has an anti-fingerprint coating on its surface to ensure that fingerprints are not left behind. Figure 2This is a schematic flowchart illustrating the process of treating the surface of a fingerprint sensor using an anti-fingerprint coating, as provided by this utility model. Exemplarily, the surface treatment of the fingerprint sensor 110 using the anti-fingerprint coating specifically includes: Step 210, encapsulating the uncoated fingerprint plate; Step 220, fixing with a clamp; Step 230, surface cleaning; Step 240, applying a primer; Step 250, baking and cleaning; Step 26, performing a first baking and cleaning process. Step 260: Apply intermediate coat; specifically, after the first baking and cleaning process, apply intermediate coat. Step 270: Baking and cleaning; specifically, perform a second baking and cleaning process. Step 280: Apply top coat; specifically, after the second baking and cleaning process, apply top coat. Step 290: Baking; specifically, perform a third baking. Step 310: Remove fixture; specifically, remove the fixture that secures the fingerprint sensor. Step 320: Test; specifically, test the fingerprint sensor 110 treated with the anti-fingerprint coating surface treatment process. Exemplarily, the entire process should be completed in a dust removal room. The temperature range for the first and second baking is 80℃-90℃, and the baking time is 30 minutes. The temperature range for the third baking is 35℃-45℃, and the baking time is 15 minutes.

[0033] Enhanced identity authentication refers to improving the reliability of identity verification by combining target fingerprint information with traditional single authentication methods, such as using only passwords or passwords. For example, enhanced identity authentication includes: acquiring the fingerprint and identity information of the target user, generating a digital certificate based on the fingerprint and identity information, and storing the digital certificate, fingerprint, and identity information; upon receiving the target user's fingerprint information uploaded by the fingerprint sensor 110, retrieving the stored digital certificate corresponding to the target fingerprint information based on the target fingerprint information, signing the digital certificate to obtain a signature value; verifying the validity of the signature value, and performing enhanced identity authentication on the target user based on the validity of the signature value. Specifically, the digital certificate is an electronic credential bound to the target user's identity, which needs to be downloaded from a remote authentication website and stored in the security chip 120. Retrieving the stored digital certificate corresponding to the target fingerprint information means comparing the acquired target fingerprint information with the stored fingerprint information; if a fingerprint matching the target fingerprint information exists, the corresponding digital certificate is retrieved. Identity information refers to the information matching the target user's identity obtained through preliminary identity verification based on the username and password information.

[0034] Security chip 120 is a chip with a higher security level than mouse chip 100. For example, after enhanced authentication of the target user, security chip 120 determines the target user's application permission scope based on the target user's identity information and grants the target user application permissions within that scope. For example, security chip 120 is a national cryptographic level 2 fingerprint chip module. The national cryptographic level 2 fingerprint module consists of a national cryptographic level 2 security chip and a high-performance, low-power fingerprint sensor. It adopts a match-on-chip (MOC) working mode, meaning that all fingerprint data acquisition, processing, storage, comparison, and management are implemented within the national cryptographic level 2 security chip 120, ensuring the security of personal biometric data throughout its entire lifecycle.

[0035] The technical solution of this utility model embodiment establishes a dual security authentication system of initial identity authentication and target fingerprint information authentication by setting a mouse chip 100 to achieve preliminary identity authentication, a fingerprint sensor 110 with anti-fingerprint coating to collect target fingerprint information, a security chip 120 to complete enhanced identity authentication, and a wireless transmitter 130 to transmit data. This solves the problems of insufficient security of traditional fingerprint mouse single-factor authentication and easy fingerprint residue leading to information leakage, and increases the security guarantee of information data secure transmission.

[0036] Optionally, the wireless transmitter 130 is a 2.4G transmitter.

[0037] A 2.4G transmitter is a wireless signal transmitting device that operates in the 2.4GHz frequency band. The point-to-point dedicated communication link of a 2.4G transmitter helps prevent data transmission and ensures secure data transmission from being intercepted during transmission.

[0038] Optionally, the wireless transmitter 130 and the security chip 120 are connected via a UART serial port.

[0039] UART (Universal Asynchronous Receiver / Transmitter) is used to enable stable and simple bidirectional data transmission between the wireless transmitter 130 and the security chip 120. UART does not require an additional clock line to synchronize the transmission rhythm of the two devices; instead, it relies on pre-agreed communication parameters to ensure correct data parsing. For example, the security chip 120 transmits data to the receive pin of the wireless transmitter 130 via the UART's transmit pin; after receiving the data, the wireless transmitter 130 converts this data into wireless signals according to the previously agreed communication parameters.

[0040] Optionally, the fingerprint sensor 110 is a capacitive fingerprint sensor.

[0041] Specifically, when a user presses their finger on the surface of the fingerprint sensor 110, the different distances between the "raised" and "concave" ridges of the fingerprint and the electrodes of the fingerprint sensor 110 result in different capacitance values. The fingerprint sensor 110 detects these differences in capacitance to reconstruct a complete fingerprint image. The capacitive fingerprint sensor has an extremely fast detection speed; authentication can be completed simultaneously when the user presses the wireless fingerprint mouse, without waiting, which aligns with the instant operation habits of wireless fingerprint mice.

[0042] Figure 3 This is a structural schematic diagram of a wireless fingerprint mouse provided according to an embodiment of the present invention in practical application. For example... Figure 3 As shown, optionally, the wireless fingerprint mouse also includes a wireless receiver 140, which is installed in the computer 150 and transmits data with the wireless transmitter 130. Through the configuration of the wireless receiver 140 and the wireless transmitter 130, data transmission between the wireless fingerprint mouse and the computer is achieved.

[0043] Optionally, the wireless receiver 140 is a 2.4G receiver.

[0044] The 2.4G transmitter and receiver communicate via a 2.4G communication channel. Data transmitted by the 2.4G transmitter is sent to the wireless mouse driver of the computer 150 via the 2.4G receiver. This 2.4G receiver not only performs basic functions such as wireless data transmission and mouse data reporting between the wireless fingerprint mouse and the computer 150, but also enables data interaction between the wireless mouse driver and the security chip 120.

[0045] Figure 4 This is a system architecture diagram of a wireless fingerprint mouse in practical application according to an embodiment of the present utility model. Figure 4 As shown, optionally, the wireless receiver 140 is connected to the computer 150 via a USB interface.

[0046] The USB interface and USB HUB 141 are located inside the wireless receiver 140. The USB HUB 141 is an external expansion device based on the USB protocol, whose core function is to expand one USB interface into multiple USB interfaces, allowing the computer 150 to connect multiple USB peripherals simultaneously.

[0047] Optionally, the wireless receiver 140 includes a USB composite device 142 and a USB custom device 143.

[0048] The USB composite device 142 communicates with the mouse chip 100 via the mouse protocol, uploading the data transmitted by the mouse chip 100 to the wireless mouse driver of the computer 150.

[0049] USB custom device 143 communicates with security chip 120 via a password key protocol, uploading secure transmission data from security chip 120 to the wireless mouse driver of computer 150.

[0050] The transmitted data and secure transmitted data are used to drive the wireless mouse driver program of computer 150. For example, the transmitted data can be basic operational data of mouse chip 100, such as cursor movement and button clicks. The secure transmitted data can be preliminary authentication results or fingerprint authentication results. Driving the wireless mouse driver program of computer 150 using the transmitted data and secure transmitted data requires a data protocol, which is divided into request data and response data. The request data is the security and fingerprint application request sent from computer 150 to security chip 120; the response data is the security and fingerprint service result returned by security chip 120 to computer 150. The specific definitions of request data and response data are shown in Tables 1 and 2 below:

[0055] In the table above, CID stands for Connection Identifier, used to identify specific connections during communication, facilitating the differentiation and management of different connections. M|O indicates whether the corresponding field in each row is a mandatory or optional attribute. M represents mandatory, meaning the field must exist and be processed; O represents optional, meaning the field can be used depending on the actual situation.

[0056] Alternatively, the anti-fingerprint coating may be a nanoscale coating, a plasma coating, or a sol-gel coating.

[0057] Among them, anti-fingerprint coating technology is a special treatment method applied to the surface of various materials, which aims to reduce the retention of fingerprints and improve the cleanliness of the surface.

[0058] Specifically, the nano-coating utilizes nanotechnology to form an ultra-thin, transparent coating on the surface of the fingerprint sensor 110, effectively preventing the adsorption of grease and dirt. This coating boasts high transparency and excellent abrasion resistance without affecting the original appearance and color of the material. Plasma spraying forms an oil- and water-resistant film on the surface of the fingerprint sensor 110, enhancing the material's stain resistance and ease of cleaning. This method is suitable for larger surface treatments, providing uniform and durable protection. Sol-gel technology uses a sol-gel process to prepare the coating, which forms a cross-linked network during curing, improving surface hardness and scratch resistance. This technology effectively enhances the material's durability and long-term protective performance. The use of anti-fingerprint coating technology not only improves surface smoothness and reduces friction, resulting in a smoother touch and optimized user experience, but also reduces cleaning and maintenance needs. Its oil and water repellency simplifies the cleaning process and lowers maintenance costs. Furthermore, this technology enhances the material's abrasion resistance and resistance to chemical corrosion, effectively extending product lifespan. For example, this anti-fingerprint coating technology can also be widely used in many fields: in electronic products, it can be used for mobile phone screens, computer monitors, camera lenses, etc.; in home appliances, it can be used for stainless steel panels, glass doors, etc., to improve product durability and reduce cleaning frequency; in the automotive industry, it can be used for car windows, dashboard screens, touch screens, etc.

[0059] The application of the security chip 120 and the surface treatment process of the fingerprint sensor 110 in this application are applicable to various data security devices used in the technological upgrading and transformation of the energy sector. Applying the anti-fingerprint coating surface treatment process to the fingerprint surface of a wireless fingerprint mouse provides the fingerprint sensor 110, which is frequently touched by the user's fingers, with anti-fingerprint residue functionality, improving the overall security level of the product. In a mouse with invalid fingerprints, the application of the security chip 120 improves the overall information security level of the mouse product, while the application of the surface treatment process of the fingerprint sensor 110 improves the physical security level, thereby achieving "dual security" of privacy and information security.

Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
