The embodiment of the invention provides an anti-counterfeiting authentication device, and the specific structure can be shown as figure 1. The anti-counterfeiting authentication device comprises two parts, namely ahost 100 and aload 200, wherein thehost 100 is used for supplying power to theload 200, controlling theload 200 to work and the like. In one embodiment where the load is an atomizer, the load is primarily used to atomize the tobacco smoke to produce an aerosol. Thehost 100 and theload 200 are cooperatively used, and thehost 100 and theload 200 can be detached and combined. Specifically, thehost 100 includes arechargeable battery 110, aswitch switching unit 120 and acontrol unit 130, theload 200 includes anauthentication unit 210, an output terminal of therechargeable battery 110 is connected to an input terminal of theswitch switching unit 120, a control terminal of theswitch switching unit 120 is connected to a first terminal of thecontrol unit 130, an output terminal of theswitch switching unit 120 is connected to a power supply terminal of theload 200, a second terminal of thecontrol unit 130 is connected to an output terminal of theauthentication unit 210, and an output terminal of therechargeable battery 110 is further connected to a power supply terminal of theauthentication unit 210 and a power supply terminal of thecontrol unit 130;
theauthentication unit 210 is configured to send the load identifier to thecontrol unit 130, so that thecontrol unit 130 authenticates theload 200 according to the load identifier, and when the authentication is passed, thecontrol unit 130 outputs a first control signal to theswitch switching unit 120, so that therechargeable battery 110 supplies power to theload 200 through theswitch switching unit 120.
Theauthentication unit 210 is configured to send the identifier of theload 200 to thecontrol unit 130, so that thecontrol unit 130 authenticates theload 200 according to the identifier of theload 200, and when the authentication is passed, thecontrol unit 130 outputs a first control signal to theswitch switching unit 120, so that therechargeable battery 110 supplies power to theload 200 through theswitch switching unit 120.
In this embodiment, theauthentication unit 210 stores the identifier of theload 200, when thehost 100 is connected to theload 200 in a matching manner, theauthentication unit 210 sends the identifier of theload 200 to thecontrol unit 130, when thecontrol unit 130 receives the identifier of theload 200, thecontrol unit 130 authenticates theload 200 by determining whether the identifier of theload 200 is consistent with the identifier stored in thecontrol unit 130, if the identifier of theload 200 is consistent with the identifier stored in thecontrol unit 130, the authentication is passed, otherwise, the authentication is not passed. Of course, in order to prevent the identification of theload 200 in theauthentication unit 210 from being tampered with, the identification of theload 200 may be encrypted and stored in theauthentication unit 210 after encryption, and at the same time, a key for decrypting the identification of theload 200 is stored in thecontrol unit 130; when theload 200 is authenticated, theauthentication unit 210 sends the encrypted load identifier to thecontrol unit 130, and after receiving the encrypted load identifier, thecontrol unit 130 decrypts the encrypted load identifier by using the key, and if the decryption is successful, the authentication is passed, otherwise, the authentication is not passed. When the authentication is passed, theauthentication unit 210 sends a first control signal to theswitch switching unit 120 to control the switch unit to switch to the on state, so that therechargeable battery 110 outputs the direct current to supply power to theload 200.
The above embodiment can prevent the load 2 produced by a non-legitimate vendor from operating by adding theauthentication unit 210 to the load and transmitting the load identifier to the control unit through theauthentication unit 210 to authenticate theload 200.
Further, in order to separately supply power to theauthentication unit 210 and avoid damage to theauthentication unit 210 due to unstable supply voltage of therechargeable battery 110, thehost 100 may further include avoltage stabilizing unit 140, and the output terminal of therechargeable battery 110 is connected to the power supply terminal of theauthentication unit 210 via thevoltage stabilizing unit 140. In this embodiment, when thehost 100 is connected to theload 200, the dc power output from therechargeable battery 110 is output to theauthentication unit 210 through the voltage stabilizing function of the voltage stabilizing unit 220 to supply power to theauthentication unit 210. The voltage regulation unit 220 may be a low dropout linear regulator (LDO), for example, and thevoltage regulation unit 140 may be disposed in the load.
In addition, theload 200 may further include a resistor, and the output terminal of the voltage stabilizing unit 220 is connected to the power supply terminal of theauthentication unit 210 via the resistor. The resistor is used to limit the current output by the voltage regulator 220 to prevent theauthentication unit 210 from being damaged by excessive current. It should be noted that the above resistor is only one equivalent resistor, and in the specific implementation, a plurality of resistors may be connected in series instead.
Further, thehost 100 further includes awireless transmission unit 150, and a terminal of thewireless transmission unit 150 is connected to a third terminal of thecontrol unit 130, wherein thewireless transmission unit 150 is configured to be in communication connection with the terminal device when theload 200 passes the authentication and receives a second control signal output by thecontrol unit 130; thewireless transmission unit 150 is further configured to output a third control signal to thecontrol unit 130 when the terminal device passes face recognition of the user, so that thecontrol unit 130 outputs the first control to theswitch switching unit 120 after receiving the third control signal.

The terminal device can be an intelligent device with a camera shooting function, such as a mobile phone, a tablet computer and the like. After thehost 100 is in communication connection with the terminal device, the terminal device collects face feature data of a user, compares the data with the identity information in the database, and when the comparison result shows that the age of the user is greater than or equal to 18 years old (i.e., a yearly person), the face recognition is passed, and the anti-regular pattern is not passed. When the face recognition is passed, thewireless transmission unit 150 outputs a third control signal to thecontrol unit 130, so that after thecontrol unit 130 receives the third control signal, the first control is output to theswitch switching unit 120, thereby controlling theswitch switching unit 120 to be in a conducting state.
