Description

Technical Field

[0001] This invention relates to the field of mobile terminal security control technology, specifically to an NFC near-field authorization system and method. Background Technology

[0002] With the rapid development of artificial intelligence technology, AI agents running on mobile terminals (such as smartphones and tablets) have become highly autonomous and can automatically perform complex tasks, such as automatically grabbing orders, making bulk payments, or automatically signing electronic contracts.

[0003] However, existing authorization models for AI-powered mobile terminals primarily rely on software-level authentication (such as passwords and biometrics). This single authentication method presents significant security vulnerabilities when facing highly capable AI agents.

[0004] First, when AI-powered mobile terminals involve payments, order submissions, signing, or other irreversible operations, existing systems still heavily rely on real-time human confirmation, such as entering passwords, clicking confirmation again, or re-initiating the authorization process. This forces the AI-assisted operation to be interrupted. In high-time-sensitivity or high-frequency operation scenarios, this interruption mechanism not only reduces efficiency but may also lead to task failure. In addition, when AI-powered mobile terminals perform operations such as proxying GUIs, they are often judged as unauthorized behavior by existing applications or service systems, resulting in transaction obstruction and security concerns.

[0005] Therefore, how to introduce an underlying hardware authorization logic that requires the presence of a user entity for irreversible operation nodes while retaining the convenience of AI agents automatically executing tasks is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] In order to overcome the shortcomings and deficiencies of the existing technology, the present invention aims to provide an NFC near-field authorization system and method, which introduces an NFC ring body as a physical key and uses the physical characteristics of near-field sensing to control the mobile terminal to transmit permissions for irreversible hardware operations, thereby ensuring the smoothness and security of the AI ​​agent.

[0007] This invention is achieved through the following technical solution: In a first aspect, the present invention discloses an NFC near-field authorization system, comprising: The device includes an NFC ring body and a mobile terminal device. The NFC ring body is equipped with a near-field communication chip and an induction coil, and the mobile terminal device is equipped with a processor, a near-field authorization receiving module, a wireless communication module and a storage unit. The near-field authorization receiving module is electrically connected to the processor and is used to receive the near-field authorization signal when the NFC ring body enters a preset sensing distance; The mobile terminal device is also equipped with an artificial intelligence agent module and an authorized control unit for the processor to execute; The authorization control unit is configured to generate a hardware enable instruction only when the near-field authorization receiving module receives the near-field authorization signal and transmits it to the processor, thereby driving the wireless communication module to transmit data packets of payment, order, or signing to complete an irreversible operation.

[0008] In conjunction with the first aspect, the NFC ring body is further described as a passive device, and the induction coil is used to generate electricity through the electromagnetic field emitted by the near-field authorization receiving module, so as to drive the near-field communication chip to send the near-field authorization signal.

[0009] In conjunction with the first aspect, the near-field communication chip further stores only a personalized, unique identification code.

[0010] In conjunction with the first aspect, the mobile terminal device further includes a human-machine interface unit, which is one or more of a display screen, a speaker, or a vibration motor. After the processor and the wireless communication module complete data transmission, the processor sends a feedback signal to the human-machine interface unit to generate a prompt.

[0011] In conjunction with the first aspect, the artificial intelligence agent module is permanently located in the background thread of the mobile terminal device and is logically connected to the authorized control unit. When the near-field authorization receiving module does not sense the NFC ring body, the authorization control unit locks the wireless communication module's transmission permission for the irreversible operation.

[0012] In conjunction with the first aspect, the NFC ring body is a ring-shaped structure made of ceramic, metal or silicone material, and the induction coil is arranged around the inside of the ring structure to form an omnidirectional induction field pattern.

[0013] Secondly, the present invention discloses an NFC near-field authorization method, characterized by comprising the following steps: Initiate the task process on the mobile terminal and initiate the near-field authorization reception process; The task flow is executed automatically by using an artificial intelligence agent to operate the graphical user interface. When the task process reaches the irreversible operation node, execution is paused and the presence of a specific NFC ring body is checked within the near field sensing range of the mobile terminal. If an instant authorization confirmation signal is detected from the NFC ring itself, the authorization is deemed successful. Based on the authorization approval determination, the AI ​​agent is allowed to complete the irreversible operation; if the signal is not detected, the operation is refused.

[0014] In conjunction with the second aspect, the NFC ring is worn on the user's finger as a physical credential proving the user's presence, and the authorization determination step is based on a dual-locking logic: that is, the mobile terminal's computing power and the NFC ring's near-field physical signal must be present simultaneously in order to unlock the irreversible operation.

[0015] The beneficial effects of this invention are: This invention discloses an NFC near-field authorization system and method. By incorporating a near-field authorization receiving module and a wireless communication module, the system addresses the security risks of remote hijacking or loss of a single mobile terminal. Specifically, the device requires both the NFC ring and the mobile terminal to be within a preset sensing distance to trigger operation, ensuring that irreversible operations are always initiated by the user in person. Without the NFC ring present, the wireless communication module cannot obtain the hardware enable command, thus physically cutting off the transmission path of sensitive data packets such as payment information. Even if the software layer is compromised, fraudulent transactions cannot be completed, balancing security and ease of use. Attached Figure Description

Detailed Implementation

[0020] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figure 1 As shown, this embodiment discloses an NFC near-field authorization system, which includes an NFC ring body 100 and a mobile terminal device 200.

[0022] The mobile terminal device 200 (such as a smartphone, AR glasses, etc.) internally includes a processor 201, a near-field authorization receiving module 202, a wireless communication module 203, and a storage unit 204. The near-field authorization receiving module 202 is electrically connected to the processor 201 and is configured to establish a specific sensing field to receive the near-field authorization signal when the NFC ring body 100 enters a preset sensing distance. The mobile terminal device 200 also includes an artificial intelligence agent module 205 and an authorization control unit 206 executed by the processor 201. The artificial intelligence agent module 205 resides in the background thread of the mobile terminal device 200 and is responsible for automatically executing user-defined tasks. The authorization control unit 206 is logically connected to the artificial intelligence agent module 205, serving as a final safety valve before performing high-risk operations.

[0023] Regarding the structure of the NFC ring body 100, in this embodiment, the NFC ring body 100 is a ring-shaped structure made of ceramic, metal, or silicone. The NFC ring body 100 contains a near-field communication chip 101 and an induction coil 102. To ensure sensing sensitivity, the induction coil 102 is arranged around the inside of the ring-shaped structure to form an omnidirectional sensing field, allowing the user to complete authentication without adjusting the ring angle.

[0024] Specifically, the NFC ring body 100 is a passive device without its own battery. The induction coil 102 is used to generate electricity through the electromagnetic field emitted by the near-field authorization receiving module 202, converting magnetic energy into electrical energy to drive the near-field communication chip 101 to send the near-field authorization signal. In terms of data privacy, the near-field communication chip 101 only stores a personalized unique identifier (UID) and does not store any biometric features or account information, thus achieving the separation of physical keys and personal privacy.

[0025] The core logic of this embodiment lies in the control of the wireless communication module 203 by the authorization control unit 206. When the near-field authorization receiving module 202 does not sense the NFC ring body 100, the authorization control unit 206 locks the wireless communication module 203's transmission permission for the irreversible operation. At this time, even if the artificial intelligence agent module 205 issues a payment request, the data cannot be sent due to the lack of hardware-level enable. The authorization control unit 206 is configured to generate a hardware enable instruction only when the near-field authorization receiving module 202 receives the near-field authorization signal and transmits it to the processor 201, driving the wireless communication module 203 to transmit payment, order, or signing data packets to complete the irreversible operation.

[0026] To improve user experience and ensure users are aware of their authorization status, such as Figure 1 As shown, the mobile terminal device 200 also includes a human-machine interface unit 207, which is one or more of a display screen, a speaker, or a vibration motor.

[0027] In actual operation, when the authorization control unit 206 issues a hardware enable command and the processor 201 completes data transmission with the wireless communication module 203, the processor 201 sends a feedback signal to the human-machine interface unit 207 to generate a prompt. For example, if the mobile terminal device 200 is a mobile phone, it can generate a specific short vibration and display the message "Authorization successful, payment completed" on the screen; if the mobile terminal device 200 is a smart wearable device without a screen, it can play a specific prompt sound. This feedback mechanism constitutes a complete interactive closed loop.

[0028] like Figure 2 As shown, this embodiment also provides an NFC near-field authorization method, which ensures security through the collaborative work of a software agent and a hardware entity. The method includes the following steps: Startup steps: The user starts the task process on the mobile terminal (e.g., start the task of "automatically grabbing concert tickets"). At the same time, the terminal background starts the near field authorization receiving process, and the near field authorization receiving module 202 enters the standby detection state.

[0029] Proxy execution steps: The AI ​​proxy module 205 automatically operates the graphical user interface (GUI) to execute the task flow. During this stage, the AI ​​proxy simulates tedious user operations such as clicking, inputting information, and filtering products, requiring no user intervention.

[0030] Detection Steps: When the task flow reaches an irreversible operation node (such as clicking "Confirm Payment", "Submit High-Value Order", or "Sign Legally Valid Contract"), the system logic forcibly suspends execution. At this time, the processor 201 checks whether a specific NFC ring body 100 exists within the near-field sensing range of the mobile terminal.

[0031] Authorization determination step: This step is based on a dual-lock logic: the mobile terminal's computing power (AI agent logic ready) and the NFC ring's near-field physical signal (proof of the user's physical presence) must be simultaneously present to unlock the irreversible operation. Specifically, if the near-field authorization receiving module 202 detects an immediate authorization confirmation signal from the NFC ring 100, the authorization is deemed successful; if the signal is not detected within a timeout, the authorization is deemed to have failed. Since the NFC ring 100 is worn on the user's finger, its near-field signal directly serves as physical proof of the user's presence.

[0032] Execution steps: Based on the authorization approval determination, the authorization control unit 206 issues a hardware enable command, allowing the artificial intelligence agent to complete the irreversible operation; if the signal is not detected, the operation is refused, and the task is automatically suspended or canceled, thereby preventing the AI ​​from overstepping its authority in the absence of user supervision.

[0033] In summary, the NFC near-field authorization system and method of the present invention, by setting up a near-field authorization receiving module and a wireless communication module, solves the security risks of a single mobile terminal in scenarios of remote hijacking or loss. Specifically, this device requires the NFC ring and the mobile terminal device to be within a preset sensing distance to trigger operation, ensuring that irreversible operation must be the user's active intention on-site. If the NFC ring is not present, the wireless communication module cannot obtain the hardware enable command, thereby physically cutting off the transmission path of sensitive data packets such as payment information. Even if the software layer is compromised, fraudulent transactions cannot be completed, thus balancing security and smooth operation.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
