Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides an apparatus security verification system, as shown in fig. 1, which includes a security apparatus 11 that has been authenticated by administrator information, an apparatus to be verified 15, and an authentication server 13.
The security device 11 which passes the administrator information authentication 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 administrator information authentication to change multiple screen colors according to the authorization code;
the device to be verified 15 sequentially reads multiple screen color information from the EInk screen of the security device 11 that has passed the administrator information authentication through a grayscale 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 device 15 to be verified as a security device when the verification code passes security verification, and sends verification passing information to the device 15 to be verified;
and 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 a device a that has performed the administrator information authentication, and the device to be verified 15 is a 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 grayscale 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 this authentication, which is usually set as a number or string. And after the device A receives the authorization code, controlling an EInk screen on the device A to display the corresponding screen color. And (3) an authorization stage: after reading the information of the multiple screen colors of the EInk screen on the device A through the gray sensor, the device B decodes the information into corresponding authorization codes and submits the corresponding authorization codes to the authentication server 13, and if the authentication server 13 judges that the authorization codes are valid, the authorization of the device B is considered to be passed. Therefore, the equipment safety verification of the equipment to be verified is realized under the condition that a camera or a microphone is not suitable for use, and the safety verification of the equipment in a scene with higher safety level requirement is met.
Specifically, a flow of implementing the device security authentication method by the device security authentication system can be seen in fig. 2. The device A is a mobile phone A, the device B is a mobile phone B, and the authentication server is used for authenticating the mobile phone A and the mobile phone B.
The embodiment of the invention provides a device authentication method based on screen black-and-white color switching, which is applied to a device 15 to be verified as 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:
and S102, sequentially reading the screen color information of the EInk screen of the security device which passes the administrator information authentication through the gray level sensor.
In this embodiment, the security device that has passed the administrator information authentication communicates with the authentication server to obtain 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. And the equipment to be verified sequentially reads the screen color information of the EInk screen of the security equipment which passes the administrator information authentication through the gray level sensor.
The EInk is a display technology based on an electrophoresis technology. The dot particles with black and white colors float up and down in the liquid capsule under the action of the electric field to form a picture. After the picture is formed, the color particles stop moving, and the picture does not disappear even if the power is off. Therefore, when turning to a certain page, the screen does not blink. The EInk is a total reflection type, that is, the display effect is different along with the change of the ambient light. The better the external light source, the better the display effect. Therefore, the EInk electronic book is almost the same as the paper book in the clear outdoor.
The gray sensor detects the color depth by using the principle that the reflection degrees of the light of the detection surfaces with different colors are different, and the resistance values of the light returned by the photoresistors to the light of different detection surfaces are also different. When the dark color is detected, a low voltage value is output, and when the light color is detected, a high voltage value is output, so that the detection output of the high voltage value is a square wave which changes along with the color depth. Since EInk is a reflective light source, and not a luminescent light source as with an LED or LCD screen, a grayscale sensor can detect well the color identifying EInk.
Therefore, the screen color information of the EInk screen can be well read by the gray sensor.
And S104, generating a verification code 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 recognizable code, the code obtained each time is recorded, and finally, the verification code is generated according to the code obtained each time. For example, the read screen color information is recorded in binary codes, each binary code uniquely representing one kind of screen color information.
S106, sending the verification code to an authentication server; and when the verification code passes the safety verification, the authentication server feeds back verification passing information to the equipment sending the verification code.
In this embodiment, the device to be verified sends the verification code to the authentication server, so that the security authentication server performs security verification on the verification 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 which passes the administrator information authentication, and if the matching is successful, the verification code is determined to pass the security verification. At this time, the authentication server sets the device that transmitted the verification code as the secure device when the verification code passes the security verification. That is, the device to be authenticated is set as the security device, and the authentication pass information is issued to the device that sends the authentication code. That is, the authentication pass information is issued to the device to be authenticated. Therefore, the safety verification of the equipment to be verified can be realized under the condition that the camera or the microphone is not suitable for use, and the safety verification of the equipment in a scene with higher safety level requirement is met.
And 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 the security verification of the authentication server according to the verification passing information, and determines that the device to be verified becomes the security device that passes the information authentication. At this time, the verification passing information can be displayed on the screen, the user using the device to be verified is informed, and the device to be verified passes the security verification and can be used in the scene with higher security level requirement.
By implementing the method, the equipment to be verified sequentially reads the screen color information of the EInk screen of the safety equipment which passes the administrator information authentication through the gray level sensor; generating a verification code according to the screen color information read each time; sending the verification code to an authentication server; when the verification code passes the security verification, the authentication server feeds back verification passing information to the equipment sending the verification code; and receiving verification passing information fed back by the authentication server, and displaying the verification passing information. Therefore, the equipment safety verification of the equipment to be verified is realized under the condition that a camera or a microphone is not suitable for use, and the safety verification of the equipment in a scene with higher safety level requirement is met. Meanwhile, a user using the device to be verified can determine that the authentication server has set the device to be verified as the security device through the verification passing information displayed on the device, so that the device to be verified can be used for interacting network information, and the security verification of each device in a scene with high security level requirements is realized.
In one embodiment, the screen color information of the EInk screen of the security device comprises black and white. S104 comprises the following steps: if the read screen color information is black, representing the read screen color information by 0 in a binary system mode; if the read screen color information is white, representing the read screen color information by 1 in a binary system mode; and generating the verification code according to the read binary number.
In this embodiment, the device to be authenticated sets a corresponding matching identifier for the read screen color information. Specifically, the read color information of each screen is recorded in a binary coding mode. For example, the screen color information is white, represented by 1 in a binary manner. The screen color information is black, represented by 0 in a binary manner, and the authentication code is generated from the sequentially generated identifiers.
In one embodiment, S102 includes: setting sampling frequency, and sequentially reading screen color information of an EInk screen of the security device which passes the administrator information authentication through a gray sensor according to the sampling frequency.
Preferably, the sampling frequency is 4Hz, and the multiple color information sequentially read comprises black, white, black, white and white; s104 comprises the following steps: generating 00100111 binary codes according to the black, white, black, white and white read in sequence; and generating a verification code according to the binary code of the 00100111.
Preferably, the screen color information of the EInk screen is determined according to an authorization code sent to the secure device by the authentication server; when the authorization code is 1884, the screen color information sequentially transformed by the EInk screen is black, white, black, white, black and black; s104 comprises the following steps: generating 00011101011100 binary codes according to the screen color information read each time; a verification code 1884 is generated from the binary code of 00011101011100.
Specifically, 4-digit numbers and binary codes are taken as examples. Since the EInk screen corresponds to 0 when displayed in black and 1 when displayed in white, the related information can be easily recorded using a binary code. A4-digit number corresponds to a range of 0 to 9999, so 2 is required14I.e. a 14-bit encoding in binary. Setting the sampling frequency to 4Hz, sampling 4 times per second, requires 14/4, i.e. a detection time of 3.5 seconds.
If the authorization code is 1884, its corresponding binary encoding is: 00011101011100, the sampled output should be as shown in fig. 4.
For another example, if the EInk screen is displayed in the following table sequence, the output waveform corresponding to the gray sensor on the device to be verified is shown in fig. 5.
