To solve the technical problem in the background art, an embodiment of the present application provides a method for terminal security management, which is applied to a terminal, as shown in fig. 1, in one example, the terminal 100 is a smart phone. The terminal 100 has a sensor 101, a processor 102, an electrochromic film electrode plate 103, and an electrochromic film 104.
In other examples, the terminal may also be other mobile terminals (e.g., tablet computers), wearable devices (e.g., smart watches, sports bracelets, smart glasses), smart car-mounted devices, etc. having 4G or 5G communication capabilities.
The Sensor 101 is used to detect a state where the terminal is in contact with a human body, and preferably, the Sensor 101 is an SAR Sensor.
The electrochromic film electrode plate 103 is connected to the electrochromic film 104, and may apply a certain voltage to the electrochromic film 104.
The electrochromic film 104 is a material having electrochromic properties, and electrochromic is a phenomenon in which optical properties (reflectivity, transmittance, absorption, etc.) of the material undergo a stable and reversible color change under the action of an applied electric field, and is manifested as a reversible change in color and transparency in appearance. The electrochromic film is disposed on a housing of the terminal, and may be specifically a rear cover of the terminal 100 or the like, which enables a user to directly observe a color change.
The processor 102 is used as a central processing unit of the terminal 100 and is respectively connected with the sensor 101 and the electrochromic film electrode plate 103, and the processor 102 is used for acquiring detection signals of the sensor 102 and applying different voltages to the electrochromic film electrode plate 103. In other examples, the processor 102 may also be a processing chip specifically configured to perform the method steps of the embodiments of the present application.
Referring to fig. 2, in a specific example, fig. 2 is a schematic diagram illustrating steps of a method for terminal security management according to the present invention, where the method may be executed by the processor 102 in fig. 1.
In step S201, the security status of the terminal is acquired.
The security status is used to indicate whether the terminal has a risk of being damaged, where the risk may include an internal risk or an external risk, and for the internal risk, the security status may indicate whether a risk exists inside an operating system of the terminal, such as whether a virus is invaded or attacked, or whether fraud information is received, and for the external risk, the security status may indicate whether the terminal has a risk of being stolen, or a risk of being dropped, or a state of being dropped, and so on.
The security state may be obtained by detecting whether a corresponding risk condition occurs inside or outside the terminal, for example, whether the terminal is invaded or attacked by a virus may be detected by an operating system of the terminal, and if so, a corresponding signal may be sent to the processor 102 to enable the processor 102 to know the occurrence of the risk condition, and for example, whether the terminal falls or not may be determined by a triaxial sensor provided in the terminal.
In step S202, the current security level of the terminal is determined according to the acquired security state.
The safety states may be preset with corresponding safety levels according to different risk conditions, and different safety states correspond to different safety levels.
The security level is used for indicating the current security state of the terminal caused by the risk condition, if the security level is high, the terminal is in a relatively safe state, and if the security level is low, the terminal is in a relatively dangerous state.
In step S203, a preset voltage value corresponding to the security level is obtained, and the voltage value is applied to an electrochromic film electrode plate of the electrochromic film, so that the electrochromic film displays a color corresponding to the voltage value.
In the embodiment of the application, when the terminal is in different security levels, the electrochromic film arranged on the terminal shell is driven to display different colors, so that a user can intuitively acquire the current security state of the terminal.
Specifically, preset voltage values corresponding to different safety levels are preset in a system of the terminal, and the terminal applies a voltage value corresponding to the current safety level to an electrochromic film electrode plate of the electrochromic film through a processor to realize color control of the electrochromic film.
According to the terminal safety management method, when the terminal is in different safety level states, the electrochromic film is controlled to be switched to display different corresponding colors, and the user is reminded of the current safety state of the terminal in a more visual mode. Especially, when the terminal is in a screen-off state, the current potential safety hazard of the user terminal can be reminded, the protection prompt for the operation safety of the terminal is added, and the safety performance of the terminal is improved.
In a specific example, the terminal is divided into four security levels, when the terminal is at a first security level, the electrochromic film correspondingly displays a security color, and the security color can be set to be the original color or a transparent color of the terminal shell; when the terminal is in a second safety level, the electrochromic film correspondingly displays a reminding color; when the terminal is in a third safety level, the electrochromic film correspondingly displays a warning color; and when the terminal is at a fourth safety level, the electrochromic film correspondingly displays an alarm color.
The lower the security level is, the larger the current risk condition of the terminal is indicated to be, that is, the first security level is the highest, and the fourth security level is the lowest. The lower the security level, the more conspicuous the corresponding displayed color of the electrochromic film, e.g., the warning color may be dark red, the warning color may be light red, the reminder color may be yellow, etc.
Specifically, the terminal security state is determined mainly by judging whether the terminal has human body contact, whether the terminal is successfully unlocked, whether the terminal is attacked or not and other factors, wherein the terminal security state is divided in detail as follows:
a first security level indicating that the terminal is in a secure operating state, the state including at least one of: a state when a human body is in contact and has successfully unlocked, no virus intrusion or attack; or the state when no person touches, no virus invasion or attack exists during standby locking;
a second security level indicating that the security level of the terminal is lower than the first security level, the status including at least one of: in order to detect the contact of a human body, the terminal is in a locking state; or the terminal is already in an unlocked state but is not in contact with a human body;
a third security level indicating that the security level of the terminal is lower than the second security level, the status including at least one of: the terminal is in a state when the unlocking fails due to the existence of human body contact;
a fourth security level indicating a lowest security level of the terminal, the status including at least one of: the terminal is subjected to virus invasion or attack and the like.
The safety degrees of the terminals in the above four levels are sequentially reduced, the safety degree of the first safety level is highest, and the safety degree of the fourth safety level is lowest.
In this embodiment, the human body approach distance is monitored in real time by an SAR Sensor of the terminal in a state of human body contact, and when the monitored distance is smaller than a specific threshold, it is considered that a human body approaches, that is, human body contact exists. In some other examples, the human body contact state may be determined by a sensor such as a light sensor or an acceleration sensor of the terminal.
And inquiring the unlocking state of the terminal according to the state information about whether the unlocking is successful or not through a system database, and acquiring information about whether the unlocking is failed or not and the unlocking failure times if the unlocking is not successful.
The virus intrusion or attack state information confirms the terminal virus intrusion or attack situation through the real-time broadcast of the terminal antivirus application program, and can also make a judgment through detecting whether the terminal important data is tampered.
In another specific example, the four security levels have a determination sequence, and the method according to the embodiment of the present application further performs the following steps:
s301: acquiring safety state data of a terminal;
s302: detecting whether the terminal is attacked by virus, if so, executing a step S303, and if not, executing a step S304;
s303: determining that the security level of the terminal is a fourth security level, and applying a fourth voltage value to an electrochromic film electrode plate of the electrochromic film, wherein the fourth voltage value enables the electrochromic film to display an alarm color;
s304: and if the terminal is detected to be unlocked, executing step S305, and if not, executing step S306.
S305: detecting whether the terminal is in a human body contact state, if so, executing a step S307, and if not, executing a step S308;
