Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
An embodiment of the present application provides a device security verification system, as shown in fig. 1, which includes a security device 11 that has been authenticated by administrator information, a device to be verified 15, and an authentication server 13.
The security device 11 which passes the authentication of the administrator information communicates with the authentication server 13, acquires an authorization code from the authentication server 13, and controls the EInk screen of the security device 11 which passes the authentication of the administrator information to change various screen colors according to the authorization code;
the device to be verified 15 sequentially reads various screen color information from the EInk screen of the security device 11 authenticated by the administrator information through a gray level sensor, generates a verification code according to the screen color information read each time, and sends the verification code to the authentication server 13;
the authentication server 13 performs security verification on the verification code according to the authorization code, sets the equipment 15 to be verified as security equipment when the verification code passes the security verification, and sends verification passing information to the equipment 15 to be verified;
the device to be verified 15 receives the verification passing information and displays the verification passing information.
In the present embodiment, the secure device 11 that has passed the administrator information authentication is the device a that has performed the administrator information authentication, and the device to be verified 15 is the device B that is ready to apply for the system user authority authentication. Both the device a and the device B are equipped with an EInk screen and a gradation sensor, and are connected to the authentication server 13 through a network. The authentication stage is as follows: the device a communicates with the authentication server 13 to determine the authorization code for the present authentication, typically in a number or string. After the device A receives the authorization code, the EInk screen on the device A is controlled to display the corresponding screen color. Authorization phase: the equipment B reads the information of various screen colors of the EInk screen on the equipment A through the gray sensor, decodes the information into corresponding authorization codes, submits the authorization codes to the authentication server 13, and the authentication server 13 judges that the authorization codes are valid, and considers that the authorization of the equipment B passes. Therefore, the device security verification of the device to be verified is realized under the condition that the camera or the microphone is not applicable, and the security verification of the device in the scene with higher security level requirements is met.
Specifically, a flow of implementing the device security verification method by the device security verification system is shown in fig. 2. The device A is a mobile phone A, the device B is a mobile phone B, and the authentication server.
The embodiment of the application provides a device authentication method based on screen black-and-white color switching, which is applied to a device 15 to be verified shown in fig. 1. As shown in fig. 3, the device authentication method based on screen black-and-white color switching includes the following steps:
s102, sequentially reading screen color information of an EInk screen of the security device authenticated by the administrator information through a gray sensor.
In this embodiment, the security device that has passed the administrator information authentication communicates with the authentication server, acquires the authorization code, and controls the screen color information of the EInk screen according to the authorization code. The screen color information of the EInk screen includes black and white. The device to be verified sequentially reads the screen color information of the EInk screen of the security device authenticated by the administrator information through the gray sensor.
EInk is a display technology based on electrophoretic technology. And floating the dot particles with black and white colors up and down in the liquid capsule under the action of an electric field to form a picture. After the picture is formed, the color particles stop moving, and the picture does not disappear even if power is turned off. Therefore, the screen does not blink when a page is turned. EInk is totally reflective, i.e. the display effect will vary with ambient light. The better the external light source, the better the display effect. Thus, the experience of watching an EInk electronic book outdoors in sunny conditions is almost the same as that of watching a paper book.
The gray level sensor detects the color by utilizing the principle that the reflection degree of the detection surfaces with different colors is different and the resistance value of the photoresistor returned to the light with different detection surfaces is also different. The low voltage value is output when a dark color is detected, and the high voltage value is output when a light color is detected, so that its detection output is a square wave varying with the color shade. Because EInk is a reflective light source, and not a light emitting light source like an LED or LCD screen, the gray sensor can well detect and recognize the color of EInk.
Therefore, the screen color information of the EInk screen can be well read by the gray sensor.
S104, generating verification codes according to the screen color information read each time.
In this embodiment, when the device to be verified sequentially reads the screen color information of the EInk screen of the security device, the screen color information read each time is recorded, and a corresponding verification code is generated according to the recorded screen color information. The color information read each time may be converted into an internally identifiable code, the code obtained each time is recorded, and finally a verification code is generated from the code each time. For example, the read screen color information is recorded in a binary code, each binary code uniquely representing one screen color information.
S106, sending the verification code to an authentication server; the authentication server performs security verification on the verification code when receiving the verification code, and feeds back verification passing information to the device sending the verification code when the verification code passes the security verification.
In this embodiment, the device to be authenticated transmits the authentication code to the authentication server so that the authentication server performs security authentication on the authentication code. Specifically, the authentication server analyzes the verification code to obtain the code to be verified. Further, the code to be verified is matched with the authorization code sent to the security device authenticated by the administrator information, and if the matching is successful, the verification code is determined to pass the security verification. At this time, when the authentication code passes the security verification, the authentication server sets the device that transmits the authentication code as the security device. That is, the device to be authenticated is set as a secure device, and authentication passing information is issued to the device that transmits the authentication code. That is, authentication pass information is issued to the device to be authenticated. Therefore, the security verification of the equipment to be verified can be realized under the condition that the camera or the microphone is not applicable, and the security verification of the equipment in the scene with higher security level requirements is met.
S108, receiving verification passing information fed back by the authentication server and displaying the verification passing information.
In this embodiment, the device to be verified receives verification passing information fed back by the security verification server, determines that the device to be verified passes security verification of the authentication server according to the verification passing information, and determines that the device to be verified has become a security device authenticated by the verification passing information. At this time, authentication passing information may be displayed on the screen, and the user who uses the device to be authenticated may be informed that the device to be authenticated passes the security authentication, and may perform device use in a scene where the security level is required to be high.
By implementing the method, the equipment to be verified sequentially reads the screen color information of the EInk screen of the safety equipment authenticated by the administrator information through the gray level sensor; generating verification codes according to the screen color information read each time; transmitting the verification code to an authentication server; the authentication server performs security verification on the verification code when receiving the verification code, and feeds back verification passing information to equipment sending the verification code when the verification code passes the security verification; and receiving verification passing information fed back by the authentication server, and displaying the verification passing information. Therefore, the device security verification of the device to be verified is realized under the condition that the camera or the microphone is not applicable, and the security verification of the device in the scene with higher security level requirements is met. Meanwhile, a user using the equipment to be verified can determine that the authentication server sets the equipment to be verified as the safety equipment through verification passing information displayed on the equipment, so that the equipment to be verified can be used for network information interaction, and safety verification of each equipment in a scene with high safety level requirements is realized.
In one embodiment, the screen color information of the EInk screen of the security device includes black and white. S104 includes: if the read screen color information is black, indicating the read screen color information by 0 in a binary mode; if the read screen color information is white, the read screen color information is represented by 1 in a binary mode; and generating the verification code according to the read binary value.
In this embodiment, the device to be authenticated sets the corresponding matched identifier to the read screen color information. And recording the read color information of each screen by adopting a binary coding mode. For example, the screen color information is white, represented by 1 in binary. The screen color information is black, and is represented by 0 in a binary system, and a verification code is generated according to the identifiers generated in sequence.
In one embodiment, S102 includes: setting a sampling frequency, and sequentially reading screen color information of an EInk screen of the safety equipment authenticated by the administrator information through a gray sensor according to the sampling frequency.
Preferably, the sampling frequency is 4Hz, and the sequentially read multiple color information includes black, white, black, white and white; s104 includes: generating 00100111 binary codes according to the black, white, black, white and white which are sequentially read; a verification code is generated from the binary code of 00100111.
Preferably, the screen color information of the EInk screen is determined according to the authorization code sent to the security device by the authentication server; when the authorization code is 1884, the screen color information of the EInk screen which is sequentially transformed is black, white white, black, white, black; s104 includes: generating a binary code of 00011101011100 according to the screen color information read each time; a verification code of 1884 is generated from the binary of 00011101011100.
Specifically, a 4-bit number and a binary code are taken as examples. The rink screen corresponds to 0 when displayed in black and 1 when displayed in white, so that the related information can be easily recorded using a binary code. A4-bit number corresponds to a range of 0 to 9999, so 2 is required 14 I.e. 14-bit encoding in binary. Setting the sampling frequency to 4Hz, sampling 4 times per second, a detection time of 14/4, i.e. 3.5 seconds, is required.
If the authorization code is 1884, then its corresponding binary code is: 00011101011100, the output of the sample should be as shown in fig. 4.
For another example, if the EInk screen is displayed sequentially as follows, the output waveforms corresponding to the gray sensors on the device to be verified are as shown in fig. 5.
