And a light source is arranged on the side edge of the image acquisition area and works according to an image acquisition instruction. The keyboard area is provided with a letter area, a setting button, a 0 button and a confirming button. The keyboard area is mainly divided into three rows, the first row is H, S, W, and the second row is A, D, F; the third row is set, 0 or definite; the "set" key length is pressed as "cancel" function, and S,0, a and F also correspond to up, down, left, and right functions of the direction key, respectively.
A face expression recognition encryption unlocking device is internally provided with a face expression recognition encryption unlocking method; the method comprises the steps that characters of a facial expression associated character area are input by utilizing buttons of a keyboard area and an image acquisition area, the encryption of the facial expression is completed, when the facial expression is unlocked, a dynamic character password is displayed in a display area, facial image information is sequentially acquired by the image acquisition area, whether the acquired facial image information and the dynamic character password are consistent or not is judged by a central processing module, an unlocking result is displayed in the display area, and unlocking verification work is completed.
The encryption method comprises the following steps: the user presses a 'setting' key, after the user inputs a management password for confirmation, different facial expressions corresponding to characters are sequentially input through the reminding of the display area, the facial expressions and the different characters of the character area are transmitted to the central processing module for storage, the facial expressions and the different characters of the character area are associated until the facial expression recognition corresponding to all letters of the character area is completed, the 'confirming' key is pressed, and the facial expression recognition encryption is completed.
As shown in fig. 3, the specific content is: the user presses a 'setting' key and inputs a management password for confirmation, a display screen is arranged in a display area, the display screen displays 'please see the camera to input H expressions', the user inputs H facial expression images through an image acquisition area, the expressions are any facial expressions based on 6 basic expressions (Happy, Sad, surprised Wonder, Angry, disgust and Fear) of facial expression codes, any facial expression can be used, 6 basic expressions with larger characteristic difference are preferred in the text, the image acquisition area is filled with light and the obtained images are transmitted to an image preprocessing module, the facial expression images are processed by the image preprocessing module and transmitted to a face detection module and an expression recognition module to execute face characteristic extraction and expression characteristic extraction, the processed face identity characteristics and expression characteristics are transmitted to a central processing module, the central processing module stores the face identity characteristics to a storage module, and the expression characteristics are associated to be H expressions, and the output module displays H expression image entry completion through the display screen. Then pressing a 'confirm' key, displaying 'please look at the camera to input an S expression' on a display screen, inputting an S facial expression image by a user through an image acquisition area, wherein the expression is any facial expression based on 6 basic expressions (Happy, Sad, surprised Wonder, Angry, disgust disposted and Fear) of facial expression codes, and repeating the steps until the facial expression recognition corresponding to all letters is completed, pressing the 'confirm' key, and completing the encryption of the facial expression recognition.
The unlocking method during unlocking comprises the following steps: pressing a 'confirm' key, generating a dynamic password by the central processing module, displaying the dynamic password and prompting a user to look ahead on the display, acquiring face image information through the front-looking image acquisition area, comparing the acquired face image information with the internally stored face image information by the central processing module in sequence, and displaying a comparison result in sequence below the dynamic password of the display area.
The concrete contents are as follows: pressing a 'confirm' key, generating a dynamic password by a central processing module, displaying the dynamic password and prompting a user to look ahead at a camera on a display, inputting a face image by the user through a front-looking image acquisition area, supplementing light in the image acquisition area and acquiring the image and transmitting the image to an image preprocessing module, processing the face image by the image preprocessing module, transmitting the face image to a face detection module and an expression recognition module to perform face feature extraction and face expression feature extraction, transmitting the processed face identity feature and expression feature to the central processing module, comparing the face identity feature with the face identity feature of a storage module by the central processing module, and if the storage module contains the face identity, displaying letters corresponding to the face expression feature below the dynamic password on the display screen, wherein the displayed letters are invisible and are represented by a 'check mark'; and (2) the user looks at the image acquisition area again for recognition, and by analogy, after the facial expressions corresponding to all dynamic password letters are recognized all the time, the lower part of the dynamic password on the display shows that the digits are the same as the dynamic password. Then pressing a 'confirm' key, so that the processing module detects the password displayed on the display, compares the password with the dynamic password, and completes unlocking if the password is consistent with the dynamic password; if not, the display displays 'password error, re-authentication'.
According to the encryption unlocking method, each letter can be set with the expression corresponding to the meaning, memory is not needed, and the problems that a digital password is easy to forget and the like are solved. The expression of each letter can also be freely set, the problems that a digital password is easy to crack, unlocking can be realized by video camouflage of the face through single face recognition and the like are solved, even if an opposite side obtains the face of a person concerned or obtains the letter password, the expression corresponding to the letter is unknown, unlocking cannot be realized, a display screen displays a dynamic password when face expression recognition is carried out every time, then relevant personnel input letter expression recognition sequences every time, and safety is remarkably improved.
