[0002] With the rapid development of information technology, smart terminals have become an indispensable part of people's daily life and work. Whether it is a smartphone, tablet or laptop, these devices carry a large amount of personal data, including but not limited to financial information, privacy data, health records and social network accounts. However, with the increasing power of these devices and the diversification of usage scenarios, security threats are becoming more and more complex and difficult to prevent. Nowadays, smart terminals such as mobile phones are usually bound to various bank cards. Once a user is controlled by someone, financial information and privacy data can be easily obtained through such smart terminals, and the user's personal wealth security and privacy security are facing huge risks.

[0003] Existing security measures are usually focused on a single level, such as password protection or simple firewall settings, which cannot fully cover a variety of potential security threats. Traditional security measures mainly rely on simple authentication methods such as password protection, fingerprint recognition or facial recognition.

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] This application proposes a method for switching the operation mode of a smart terminal. By comprehensively evaluating the security items related to finance and privacy in the smart terminal and pre-configuring multiple security modes with higher security factors based on the comprehensive evaluation, the security of the smart terminal when processing sensitive information is significantly improved. Figure 1 The principle is shown in the attached Figure 2 The specific plan is as follows: A method for switching an operation mode of an intelligent terminal includes the following steps: 101. Evaluate the security factor of the smart terminal in normal mode based on the financial and privacy security items in the smart terminal, and pre-configure one or more security modes with higher security factors for the smart terminal, and each security mode has its own active activation conditions, passive activation conditions and security measures; 102. Acquire first information including location data and network data of the smart terminal, and determine whether the smart terminal meets the active activation condition of any security mode based on the first information: if yes, switch the smart terminal to the security mode corresponding to the active activation condition; if no, monitor the unlocking process of the smart terminal in real time, and when any passive activation condition is matched during the unlocking process, switch the smart terminal to the security mode corresponding to the passive activation condition; 103. When the smart terminal is in any security mode, obtain second information of the smart terminal including operation data and environment data, and execute security measures corresponding to the security mode based on the second information.

[0021] The present application provides a method for switching the operation mode of a smart terminal, which is mainly used to improve the security of the smart terminal when processing financial and privacy information. The method is implemented by evaluating the security factor of the smart terminal in normal mode and pre-configuring one or more security modes with higher security factors based on this. These security modes are automatically switched according to different active activation conditions or passive activation conditions. Among them, smart terminals include portable terminal devices such as wearable devices, mobile phones, tablets and laptops, which involve user personal privacy and some property information.

[0022] In this application, the security mode is based on security items. Security items can be specific software or related information in the software, such as collection information, browsing information, etc. When entering the security mode, the smart terminal will only display information such as software that is allowed to be accessed in this mode to achieve the purpose of privacy protection and property protection. For example, in a high-level security mode, security items such as bank apps on smartphones will not be displayed or access is not allowed, and security items containing private information such as photo albums and social software will not be displayed or access is not allowed.

[0023] Step 101 is the basis of the entire smart terminal operation mode switching method, the core of which is to evaluate the safety factor of the smart terminal in the normal mode and pre-configure one or more safety modes with higher safety factors.

[0024] In this application, the smart terminal needs to have certain capabilities, including: Networking capability: Connect to the Internet via Wi-Fi, cellular network, etc.

[0025] Multitasking: The ability to run multiple applications and handle different types of tasks at the same time.

[0026] User interaction interface: Provide a graphical user interface (GUI) to facilitate user operation.

[0027] Sensor integration: Built-in multiple sensors (such as GPS, accelerometer, gyroscope, etc.) to obtain environmental information.

[0028] Microphone and camera: used to obtain audio and video data around the terminal.

[0029] First, the system needs to identify and evaluate security items on smart terminals that are related to finance (such as banking applications, payment platforms, etc.) and privacy (such as address books, text messages, photos, etc.). These items usually contain the most sensitive information of users, so their security needs special attention. By clarifying which items belong to the financial and privacy categories, the system can carry out more stringent security protection for these high-risk items in a targeted manner.

[0030] Among them, security projects refer to the types of data stored or processed on smart terminals and their related access control mechanisms. These projects usually involve users' financial information and personal privacy, so special security protection measures are required. Specifically, security projects can be divided into the following categories: 1. Financial security projects Bank applications: such as Alipay, WeChat Pay, and official apps of major banks.

[0031] Investment and financial management platforms: such as stock trading software and fund trading platforms.

[0032] E-wallets: such as Apple Pay and Google Wallet.

[0033] 2. Privacy security projects Contacts: Contains contact information such as names, phone numbers, and email addresses.

[0034] SMS and instant messaging records: such as SMS, WhatsApp, and WeChat chat records.

[0035] Personal photos and videos: Private pictures and videos stored in your photo album.

[0036] Health data: such as steps, heart rate, etc. recorded by fitness trackers.

[0037] To protect these security items, the system usually sets access rights to limit which applications or users can access this data under what conditions. For example: password protection, requiring a password or fingerprint to access certain sensitive applications. Encrypted storage, using encryption algorithms such as AES to encrypt and store sensitive data. Permission management, assigning different access rights according to application needs, such as read-only or full access rights.

[0038] Based on the security items identified above, the system will evaluate the overall security factor of the smart terminal in normal mode. This includes but is not limited to access permission settings, encryption measures, network connection security, etc. The assessed security factor can help determine the security level of the current smart terminal under normal use and provide a basis for further improving the security level. Based on the assessed security factor, the system pre-configures one or more security modes with higher security factors for the smart terminal.

[0039] Among them, security mode is an operating state of the smart terminal, which improves the security of the smart terminal by enabling specific security measures. Each security mode has its own active activation conditions, passive activation conditions and corresponding security measures to deal with different levels of security threats. Smart terminals, security projects and security modes are interrelated as a whole. As a carrier, smart terminals carry various security projects; and security modes are security strategies that are dynamically adjusted according to different usage scenarios and potential threats. This design not only improves the security of smart terminals, but also effectively responds to various potential security threats without affecting the user experience.

[0040] Each security mode has specific security measures and activation conditions. Pre-configuring multiple security modes allows smart terminals to automatically adjust to the most suitable security level according to different usage scenarios and potential threats, thereby improving overall security. Each security mode has its own active activation conditions, which are usually triggered based on user operation behavior or environmental changes. For example, when the smart terminal is connected to a risky network, the high security mode is automatically activated; when the smart terminal is connected to a home network, the security mode is turned off or a security mode with a lower security factor is activated. Similarly, by detecting the location of the terminal smart terminal, the security mode is automatically switched. For example, when the smart terminal is at home, the medium security mode is activated; and in public places, the high security mode is activated. By setting clear active activation conditions, the system can quickly switch to the corresponding security mode when a specific environment or behavior is detected, and respond to potential threats in a timely manner.

[0041] In addition to active activation conditions, the system also sets some passive activation conditions to automatically switch to a higher level of security mode when abnormal behavior is detected. For example, if an incorrect password is entered three times in a row, high security mode is automatically activated. If the computer is restarted or shut down multiple times in a short period of time, high security mode is activated. Passive activation conditions can take immediate action when abnormal operations are detected to prevent unauthorized access or malicious attacks. By setting active and passive activation conditions, a dynamic response mechanism is implemented, which improves the adaptability and reaction speed of the system.

[0042] Each security mode is equipped with exclusive security measures to further enhance the security of smart terminals. Specific security measures can provide effective protection measures for different levels of security needs, ensuring that user data can be fully protected in all situations.

[0043] Regarding the evaluation of security factors and the construction of security modes. In some specific embodiments, security items involving finance and privacy in the smart terminal are obtained, and the access rights of each security item are determined; an evaluation system for evaluating the security level of the smart terminal is constructed based on the accessible number of security items and the access rights; the normal mode of the smart terminal is determined, and the security factor of the smart terminal in normal mode is evaluated according to the evaluation system to obtain a first security factor; the access rights of each security item are determined, and all access rights involved are divided into permission levels; the project types are divided according to whether the security item involves privacy or finance; multiple security modes are constructed according to the permission level, project type and the accessible number of security items, and the security factor of each security mode is higher than the first security factor.

[0044] First, you need to identify all financial and privacy-related data or applications on the smart terminal, and set specific access permissions for each security item, such as read, write, modify, delete, etc. You can mark which security items belong to the financial or privacy category by scanning the applications on the smart terminal and the data stored in them. For example, this can be achieved through API calls or file system scans. Configure these permissions in the settings interface of the smart terminal, or dynamically manage them through the application programming interface (API).

[0045] Build an evaluation system and evaluate the security factor in normal mode. Based on the number of accessible security items and access rights, build an evaluation system to quantify the security level of smart terminals. Use this evaluation system to evaluate the overall security factor of smart terminals in normal mode to obtain the first security factor. Define the scoring criteria and score according to the access rights of each security item. For example, using a 10-point system, each item is scored according to the security of its permissions. Sum up the scores of all items, calculate the total score, and divide it by the full score to get the security factor. For example, if the total score is 35 points and the full score is 50 points, the security factor is 70%.

[0046] Divide all projects involving access rights into different levels according to their security. For example, divide them into three levels: low, medium, and high. Projects that require two-factor authentication are high-level, projects that only require password verification are medium-level, and projects that do not require verification are low-level. According to the content of the project, classify it into financial or privacy categories. For example, banking applications and payment platforms are financial, and address books and photo albums are privacy.

[0047] For example, the security mode is as follows: High Security Mode: Permission level: All security items require two-factor authentication.

[0048] Project type: All financial and privacy projects have the highest level of protection enabled.

[0049] Safety factor: Assumed to be 85%.

[0050] Active activation conditions: connected to the company's internal network and located in the office.

[0051] Passive activation conditions: multiple failed unlock attempts, frequent restarts or shutdowns.

[0052] Security measures: Enable two-factor authentication, limit external device connections, and enforce encryption of all communications.

[0053] Moderate security mode: Permission level: Some items require fingerprint or facial recognition, others require password verification.

[0054] Project type: Financial projects use higher protection, and privacy projects use medium protection.

[0055] Safety factor: Assumed to be 80%.

[0056] Active activation conditions: connected to home Wi-Fi network and at home.

[0057] Passive activation conditions: abnormal behavior is detected (such as frequent switching of applications within a short period of time).

[0058] Security measures: Enable fingerprint recognition, limit background activities of certain apps, and back up data regularly.

[0059] Low security mode: Permission level: Most items only require password verification, while some items do not require verification.

[0060] Project type: Financial projects enable basic protection, while privacy projects enable lower protection.

[0061] Safety factor: Assumed to be 75%.

[0062] Active activation conditions: connected to a public Wi-Fi network and in a public place.

[0063] Passive activation condition: The device has not been used for a long time (such as no operation for more than 30 minutes).

[0064] Security measures: Enable password protection, automatically lock the screen, and remind users to pay attention to network security.

[0065] Step 102 is the key part of the entire smart terminal operation mode switching method, which mainly involves obtaining the first information of the smart terminal (such as location data and network data), and judging whether the active activation conditions of any security mode are met based on this information. If the conditions are met, switch to the corresponding security mode; otherwise, monitor the unlocking process in real time, and switch the mode when the passive activation conditions are matched.

[0066] The first information refers to various data related to the current state of the smart terminal, mainly including location data and network data. Location data can be location information provided by GPS coordinates, Wi-Fi positioning, or Bluetooth beacons. Network data includes the type of network currently connected (such as Wi-Fi, 4G / 5G) and its specific SSID (Service Set Identifier), etc.

[0067] Active activation conditions refer to conditions for automatically activating corresponding security modes when the smart terminal is in certain specific environments or connected to certain specific networks. For example, the high security mode is automatically activated when connected to the company's internal network. The first information obtained is compared with the active activation conditions of each security mode to determine whether any condition is met. If the active activation condition of a security mode is met, switch to that security mode immediately. For example, when the smart terminal is connected to a Wi-Fi network named company and the location data shows that the user is in the company's office, the system automatically activates the high security mode. After the system detects that the active activation conditions of a security mode are met, it triggers a mode switch. During the switching process, the system loads all configurations and security measures under the security mode and applies them to the smart terminal. At the same time, the system may prompt the user that it has currently switched to a new security mode.

[0068] Passive activation conditions refer to the conditions for automatically activating the corresponding security mode when certain abnormal behaviors or operations are detected during the use of the smart terminal. For example, multiple failed unlock attempts, frequent restarts or shutdowns, etc. If the smart terminal does not meet any active activation conditions, the system will continue to monitor the user's operating behavior, especially the unlocking process. The monitoring content may include the number of unlocks, the unlocking time interval, the number of incorrect passwords entered, etc. If the user's behavior is found to meet the passive activation conditions of a security mode during the monitoring process, it will immediately switch to that security mode. For example, if the user enters an incorrect password three times in a row, the high security mode will be automatically activated, requiring the user to perform additional identity authentication (such as fingerprint recognition or facial recognition).

[0069] Step 103 is a key link in the method for switching the operating mode of the smart terminal, which mainly involves obtaining the second information including operation data and environmental data when the smart terminal is in a certain security mode, and executing corresponding security measures based on this information. According to the operation data and environmental data obtained in real time, the security measures in the current security mode are dynamically adjusted to ensure that the smart terminal is always in the optimal security state. Without affecting the normal use of the user, the security level is automatically adjusted to enhance the security of the smart terminal and reduce potential security threats. Provide personalized security protection strategies based on the behavioral habits and usage scenarios of different users. Through real-time monitoring and dynamic adjustment, timely respond to potential security threats and protect users' financial and privacy data. Enable or disable certain security measures according to actual needs to avoid unnecessary resource consumption and improve the overall performance of the smart terminal.

[0070] Among them, the second information refers to various data related to the current operation behavior and environment of the smart terminal, mainly including operation data and environment data. In some specific embodiments, the operation data includes the user's operation behavior on the smart terminal, such as the number of unlock attempts, the number of wrong passwords entered, the timestamps of application startup and shutdown, the situation of frequent user application switching, the frequency of smart terminal restarts, and the frequency of shutdown. In actual applications, the API interface provided by the operating system is used to capture the user's operation behavior, record the results of each unlock attempt, the timestamps of application startup and shutdown, the number of wrong passwords entered by the user, etc. The environmental data includes the current geographical location and residence time of the smart terminal, the image information and sound information around the smart terminal, and the weather information of the geographical location. The current location coordinates are obtained through the GPS module, and the residence time of the smart terminal at this location is recorded. The image information around the smart terminal is captured by the camera, and the images are analyzed using computer vision technology to identify potential security threats (such as whether there is an unauthorized person approaching the smart terminal). The ambient sound around the smart terminal is captured by the microphone, and the audio analysis technology can be used to detect abnormal sounds (such as alarm sounds, noisy sounds). The weather information (such as temperature, humidity, weather conditions) at the location of the smart terminal is obtained through network requests.

[0071] Each security mode has corresponding security measures to deal with different security threats. For example, a high security mode may require two-factor authentication, restrict external smart terminal connections, and force encryption of all communications; a medium security mode may enable fingerprint recognition, restrict background activities of certain applications, etc. The system matches the acquired second information with the security measures of the current security mode to determine whether certain security measures need to be enabled or adjusted. If a potential security threat is found (such as multiple unlocking failures or abnormal sounds around), the corresponding advanced security measures (such as two-factor authentication or lock screen) are immediately enabled. Based on the data acquired in real time, the system can dynamically adjust the security measures in the current security mode. For example, in low security mode, if abnormal sounds are detected around the smart terminal, the system can temporarily upgrade to medium security mode and enable more security measures.

[0072] For example: High security mode: When the system detects that the user has entered an incorrect password three times in a row, it will automatically enable two-factor authentication and prompt the user to perform additional authentication (such as fingerprint recognition or facial recognition). If there are any unusual sounds around, the system will also temporarily lock the screen and send a notification to the administrator.

[0073] Moderate security mode: When the system detects that the user frequently switches between apps in a short period of time, it will temporarily limit the background activities of certain apps and enable the fingerprint recognition function. If the surrounding image shows that a stranger is approaching the smart terminal, the system will prompt the user to pay attention to safety and temporarily lock the screen.

[0074] Low security mode: When the system detects that the smart terminal has not been used for a long time (such as more than 30 minutes without operation), the system will automatically lock the screen and remind the user to pay attention to network security. If the surrounding sound is abnormal (such as alarm sound), the system will temporarily upgrade to medium security mode and enable more security measures.

[0075] The core of step 103 is to dynamically adjust the security measures in the current security mode by acquiring the operation data and environmental data (i.e., the second information) of the smart terminal in real time, so as to ensure that the smart terminal is always in the optimal security state. This method not only improves the security of the smart terminal, but also effectively responds to various potential security threats without affecting the user experience. Each security mode has clear security measures and dynamic adjustment mechanisms to ensure that appropriate protection measures can be provided in different situations. This method realizes dynamic adaptability and multi-level protection, significantly improving the overall security of the smart terminal.

[0076] In some specific embodiments, active activation conditions include: connecting to a preset network and being at a preset location; passive activation conditions include: detecting multiple unlocking attempts within a preset time, multiple restarts or shutdowns within a preset time, unlocking using a preset non-usual password, and pressing a preset button in a preset pressing method.

[0077] The preset network is set by the user and can be a secure network or an unsecure network. In actual applications, the preset network can be an unfamiliar, unauthenticated external network, such as a public place network, which may have the risk of reading user data. When it is detected that the smart terminal is connected to such a low-security network, it can switch to a higher security mode. In addition, the preset network can also be maintained by a trusted organization or individual and has a high security. For example, the internal network of a company may be equipped with security facilities such as firewalls and intrusion detection systems to effectively prevent external attacks. In the preset network environment, smart terminals can more easily access enterprise resources and services, and can also better control the behavior and permissions of smart terminals. Similarly, the preset location is also set by the user and can be a specific place, such as a company, home, public place, etc.

[0078] Passive activation conditions refer to the process of using the smart terminal, by real-time monitoring of the user's operating behavior and environmental data, when certain abnormal behaviors or potential security threats are detected, the smart terminal automatically switches to the corresponding safe mode. In some embodiments, when the passive activation condition and / or the active activation condition are used, the smart terminal enters the safe mode without any prompt. The passive activation condition is a way for the user to hint the smart terminal to enter the safe mode with a special password or a special operation form. Different fingerprints, different passwords, different expressions, pressing a specific button in a specific way, etc. can be used. For example, press the power key and volume key once, multiple times, or for a long time to control the smart terminal to enter the safe mode.

[0079] A non-common password refers to a password that the user does not frequently use or an uncommon password combination. Usually, users will set a common password for daily unlocking of smart terminals. A set of non-common passwords pre-configured by the user, when these passwords are used to unlock the smart terminal, the system considers that there may be a security threat. If the user uses an uncommon password to unlock, it may indicate that the smart terminal has been stolen or there are other security risks. In this application, the password form of non-common passwords includes character passwords, graphic passwords or biometric passwords. Under normal circumstances, users can conveniently use common passwords to unlock smart terminals and enjoy a convenient operation experience. Only when abnormal behavior (such as the use of uncommon passwords) is detected, the system will automatically take more stringent measures to ensure the security of the smart terminal. In some specific embodiments, when a preset uncommon password is used for unlocking, it specifically includes: multiple locking modes are preset in the smart terminal, and each locking mode corresponds to an uncommon password and a security mode; during the unlocking process, when it is recognized that the smart terminal is unlocked with an uncommon password, the locking mode corresponding to the uncommon password is determined to obtain the first locking mode; after confirmation, the smart terminal is switched to the security mode corresponding to the first locking mode. Each locking mode has one or more pre-configured uncommon passwords, which are different from the user's common passwords. When the user unlocks the smart terminal with an uncommon password, the system can recognize the password and automatically switch to the corresponding security mode according to the corresponding locking mode. Unlocking with an uncommon password usually means that the smart terminal may be in an abnormal state (such as being stolen or used by unauthorized persons), so higher security measures are required to protect the smart terminal and data. Different locking modes can provide different degrees of security protection to adapt to different usage scenarios and potential threats. The confirmation method can be set according to the actual situation, which can be a prompt box or entering the same or different password again.

[0080] By presetting multiple lock modes, each corresponding to different security measures and security levels, the system can provide appropriate protection according to specific circumstances. For example, a high-security mode may include two-factor authentication, restricting external smart terminal connections, and forcing encryption of all communications; a medium-security mode may enable fingerprint recognition, restricting background activities of certain applications, etc.; a low-security mode may only enable basic password protection and automatic screen lock functions. Users can preset different lock modes and non-usual passwords according to their needs and usage scenarios. For example, use a common password to unlock the smart terminal at home, and use a preset non-usual password to unlock the smart terminal in the company office or when going out. This allows for flexible response to various potential security threats in different environments. Each lock mode has specific security measures, and users can choose the appropriate lock mode according to actual needs. For example, when users expect that the smart terminal may face higher security risks (such as when used in public places), they can choose to use a non-usual password to trigger a higher level of security protection.

[0081] In some specific embodiments, it also includes: obtaining the historical operation data of the same user on the smart terminal, analyzing the user's operating habits from the historical operation data, the operating habits include data input method and input speed, access frequency and access habits of security items, and holding posture of the smart terminal; when the smart terminal is in any security mode, obtaining the user's operation data on the smart terminal, and analyzing whether the operation data conforms to the user's operating habits: if not, executing the security measures corresponding to the security mode. By analyzing the user's operating habits, the system can automatically execute corresponding security measures when abnormal operations are detected to prevent unauthorized access or malicious behavior. According to the user's actual operating habits, the system can provide more accurate security protection to adapt to different usage scenarios and potential threats.

[0082] The system obtains and analyzes the historical operation data of the same user on the smart terminal to extract the user's operation habits, such as data input method and input speed, access frequency and access habits of security items, and holding posture of the smart terminal. Data input method and input speed, such as typing speed and touch screen click frequency; access frequency and access habits of security items, such as access frequency and login time of bank apps; holding posture of smart terminals, such as the holding method reflected by sensor data. Extract the user's operation habits. For example: users usually enter passwords at a faster speed, users access financial applications at a fixed time every day, and users are accustomed to operating smart terminals with their left hand. The system stores these operation habits as a habit model for subsequent comparison and anomaly detection.

[0083] When the smart terminal is in any security mode, the system will obtain the user's operation data in real time and compare it with the operation habits analyzed previously. If the current operation data does not conform to the user's operation habits, the system will determine it as abnormal behavior and automatically execute the security measures corresponding to the security mode. In some cases, the system may require the user to perform additional identity authentication (such as fingerprint recognition or facial recognition) to confirm the identity. When the system detects that the current operation does not conform to the user's habits, it will automatically enable a higher security level to prevent the smart terminal from being accessed by unauthorized persons. For example, the user's smart terminal is suddenly lost, and the person who picked up the smart terminal tries to unlock the smart terminal. Because its operation method (such as slow input speed and inconsistent holding posture) does not conform to the user's habits, the system detects this abnormal behavior and immediately activates a high security mode, requiring additional identity authentication (such as fingerprint recognition or facial recognition), and enabling other advanced security measures (such as limiting external smart terminal connections and forcing encryption of all communications).

[0084] In some specific embodiments, it also includes: when the smart terminal is in any security mode, the security items that are allowed to be accessed in the security mode are treated as non-restricted access items, and the security items that are not allowed to be accessed are treated as restricted access items; the operation data of the current user on the smart terminal is obtained, and the access intentions of the current user to the financial and privacy security items are evaluated by parsing the number of accesses to each restricted access item and the non-restricted access item in the operation data, and the first access intention and the second access intention are obtained; according to the first access intention, it is determined whether to include the non-restricted access items of the financial category in the security mode into the restricted access items, and according to the second access intention, it is determined whether to include the non-restricted access items of the privacy category in the security mode into the restricted access items. By analyzing the user's operation data, the system can evaluate the user's access intention in real time, and dynamically adjust the access rights of the financial and privacy security items according to these intentions. In this way, a more flexible user experience can be provided under the premise of ensuring security. According to the user's actual access behavior, the system can more accurately determine which items need to be further restricted in access, thereby providing personalized security protection. When an abnormal access intention is detected, the system will automatically take measures to include certain non-restricted access items into restricted access items to ensure the security of the smart terminal. It not only enhances the security protection capabilities of smart terminals, but also provides personalized security measures based on actual needs to adapt to different usage scenarios and potential threats.

[0085] The system sets clear financial and privacy security items for each security mode, and classifies them into restricted access items and unrestricted access items. Security items that are allowed to be accessed are considered unrestricted access items, and security items that are not allowed to be accessed are considered restricted access items. Unrestricted access items: security items that users can access freely, such as checking weather information, browsing news, etc. Restricted access items: security items that users need additional verification or cannot access, such as bank account information, personal information, etc. When entering a certain security mode, the system initializes restricted access items and unrestricted access items according to preset rules.

[0086] The system collects user operation data in real time, including but not limited to: the number of times financial security items are accessed, the number of times privacy security items are accessed, the user's operation time and frequency, etc. The current operation data is compared with the previously set restricted access items and non-restricted access items, and the number of times the user accesses each item is counted. Based on the user's operation data, the system evaluates the current user's access intention to financial and privacy security items respectively. First access intention: the user's access intention to financial security items, such as frequent access to bank account information may indicate that the user has strong financial needs. Second access intention: the user's access intention to privacy security items, such as frequent access to personal information may indicate that the user has strong privacy needs. Thresholds or other standards can be set in advance to determine whether the user's access intention is abnormal. For example, if a user frequently accesses multiple financial security items in a short period of time, it may indicate a potential security threat.

[0087] Based on the evaluated first access intention and second access intention, the system decides whether to include certain non-restricted access items in restricted access items. If the system detects that the user's access intention to financial security items is abnormal (such as frequent access), some financial items that were originally allowed to be accessed are included in restricted access items. If the system detects that the user's access intention to privacy security items is abnormal (such as frequent access), some privacy items that were originally allowed to be accessed are included in restricted access items. After confirmation, the system updates the list of restricted access items and non-restricted access items in the current security mode and notifies the user of the corresponding changes. When the system detects that the user's access intention is abnormal, it automatically includes certain non-restricted access items in restricted access items to prevent unauthorized access to sensitive information on smart terminals. For example, when a user is working in a company office, the smart terminal is suddenly lost. The person who picked up the smart terminal tries to frequently access multiple financial security items (such as bank account information). The system detects this abnormal behavior and immediately removes these financial items from non-restricted access items and changes them to restricted access items, requiring additional authentication (such as fingerprint recognition or facial recognition) to access.

[0088] In some specific embodiments, the total number of visits to each restricted access item in the operation data is taken as the first total number, and the total number of visits to each unrestricted access item in the operation data is taken as the second total number; the ratio of the number of visits to financial restricted access items in the operation data to the first total number is calculated to obtain the financial restriction ratio, the ratio of the number of visits to financial unrestricted access items in the operation data to the second total number is calculated to obtain the financial unrestricted ratio, and the first access intention is obtained based on the financial restriction ratio and the financial unrestricted ratio; the ratio of the number of visits to privacy restricted access items in the operation data to the first total number is calculated to obtain the privacy restriction ratio, the ratio of the number of visits to privacy unrestricted access items in the operation data to the second total number is calculated to obtain the privacy unrestricted ratio, and the second access intention is obtained based on the privacy restriction ratio and the privacy unrestricted ratio. The principle of the first access intention is as shown in the attached figure. Figure 3 As shown, the principle of the second access intention is as shown in the attached Figure 4 shown.

[0089] The system divides the user's operation data into the number of visits to restricted access items and unrestricted access items, and further divides them into financial and privacy security items. The user's access intention is evaluated by calculating the proportion of the number of visits to financial and privacy restricted access items and unrestricted access items to the total number of visits. Based on the calculated access intention (first access intention and second access intention), the system decides whether to adjust the access rights of certain items to enhance security. When the system detects that the user's access intention is abnormal, it automatically includes certain unrestricted access items in the restricted access items to prevent unauthorized personnel from accessing sensitive information on smart terminals.

[0090] In some specific embodiments, if the difference between the financial restriction ratio and the financial non-restriction ratio in the first access intention is greater than a preset difference, the financial non-restriction access items in the security mode are included in the restricted access items; if the difference between the privacy restriction ratio and the privacy non-restriction ratio in the second access intention is greater than a preset difference, the privacy non-restriction access items in the security mode are included in the restricted access items. The preset difference is a key threshold used by the system to determine whether the user's access intention is abnormal. It determines under what circumstances the system will adjust certain non-restriction access items to restricted access items.

[0091] Operation data classification: the total number of visits to each restricted access item in the operation data is taken as the first total number, and the total number of visits to each non-restricted access item in the operation data is taken as the second total number.

[0092] Proportional calculation: Finance: Calculate the ratio of the number of visits to finance-restricted access items to the first total number of visits to obtain the finance-restricted ratio. Calculate the ratio of the number of visits to finance-unrestricted access items to the second total number of visits to obtain the finance-unrestricted ratio.

[0093] Privacy: Calculate the ratio of the number of visits to privacy-restricted access items to the first total number of visits to obtain the privacy-restricted ratio. Calculate the ratio of the number of visits to privacy-unrestricted access items to the second total number of visits to obtain the privacy-unrestricted ratio.

[0094] Access intention assessment: Based on the financial restriction ratio and the financial non-restriction ratio, the user's access intention to financial security projects (first access intention) is assessed. Based on the privacy restriction ratio and the privacy non-restriction ratio, the user's access intention to privacy security projects (second access intention) is assessed.

[0095] Dynamically adjust access rights: Based on the first access intent, determine whether to include certain financial non-restricted access items into restricted access items. Based on the second access intent, determine whether to include certain privacy non-restricted access items into restricted access items.

[0096] For example, when a user is working in a company office, the smart terminal is suddenly lost, and the person who picked up the smart terminal tries to frequently access multiple financial security items (such as bank account information).

[0097] Operational data: First total number: The total number of visits to all restricted access items is 50 times.

[0098] Second total number: The total number of visits to all non-restricted access items is 100 times.

[0099] The number of accesses to financial restricted-access items is 30 times.

[0100] Number of visits to financial non-restricted access projects: 70 times.

[0101] Calculate the ratio: Financial limit ratio = 30 / 50 = 60% Financial non-restricted ratio = 70 / 100 = 70% Evaluate visit intent: First access intention: Due to the high proportion of financial restrictions (60%), it shows that users have strong financial needs and frequently access restricted items, so enhanced security measures may be needed.

[0102] The system detects that the user frequently accesses multiple financial security items and determines it as abnormal behavior. The system automatically activates high security mode, requires the user to perform additional identity verification (such as fingerprint recognition or facial recognition), and removes these financial items from non-restricted access items and changes them to restricted access items to ensure the security of sensitive information.

[0103] The access permission adjustment scheme for security items based on access intention monitors the user's operation data in real time, calculates the access ratio of financial and privacy restricted access items and unrestricted access items, evaluates the user's access intention, and dynamically adjusts the access permission based on these intentions. This method not only enhances the security protection capabilities of smart terminals, but also provides personalized security measures based on actual needs to adapt to different usage scenarios and potential threats.

[0104] The setting of the preset difference needs to take into account multiple factors, including security requirements, user experience, historical data and statistical analysis.

[0105] Based on historical data analysis: Collect a large amount of user operation data, including normal access behavior and abnormal access behavior. By analyzing this data, find out the difference between normal and abnormal access behavior. Perform statistical analysis on historical data, calculate the access ratio and difference of financial and privacy restricted access items and non-restricted access items. Find a reasonable difference range so that most normal access behaviors will not trigger permission adjustment, while abnormal access behaviors can be effectively identified. According to the statistical results, select a suitable difference as the preset difference. This difference should be able to minimize false positives (i.e. normal access behaviors are mistakenly judged as abnormal) while ensuring security. If the statistical results show that the difference between the financial restriction ratio and the financial non-restriction ratio of normal users is usually no more than 5%, then the preset difference can be set to 5% or slightly higher than 5% (such as 6%) to leave a certain margin for error.

[0106] Based on risk assessment: Different risk levels are divided according to different application scenarios and user groups. For example, smart terminals of enterprise users may face higher security risks, while smart terminals of personal users are relatively low. Set different preset differentials for different risk levels. For high-risk scenarios, a lower preset differential can be set to more sensitively detect potential security threats; for low-risk scenarios, a higher preset differential can be set to reduce unnecessary permission adjustments. Example: High-risk scenarios (such as enterprise users): The preset differential can be set to 3%. Low-risk scenarios (such as ordinary personal users): The preset differential can be set to 8%.

[0107] In actual applications, a more conservative preset difference (such as 5%-10%) can be set first to ensure the stability and security of the system. Avoid too many false positives or false negatives due to unreasonable initial settings. As the system runs longer, more user data and feedback information are gradually accumulated, and the preset difference is adjusted dynamically. Make the preset difference more in line with actual usage, improve the accuracy of the system and user experience. In addition to relying solely on the difference, other indicators (such as the user's geographic location, operating habits, etc.) can also be combined for a multi-dimensional comprehensive evaluation to improve the overall judgment ability of the system and reduce the risk of misjudgment caused by a single indicator.
