The following describes the implementation process of the present embodiment in detail:
and S1, generating the conference entrance password and informing the expected participants of the conference entrance password.
Because follow-up needs gather facial information when inputing the income password, consequently, the length of inputing the password needs reasonable setting, if the setting of income password is too short for the user input time is too short, and then in the short time, can't be fine carry out facial discernment, influences follow-up facial matching process, and the convenience then can be reduced to the income password of overlength.
In order to set a reasonable-length session password, specifically, generating the session password includes the following steps:
s1.1, acquiring corresponding typing frequency information based on predicted participants;
specifically, assuming that the session password is a pure digital password, the method for acquiring the typing frequency information includes the following steps:
s1.1.1, before generating the conference password, acquiring the information of the current input equipment,
s1.1.2, before generating the conference password, collecting and storing the password in real timeiThe keyboard of the individual intended participant enters the information.
Wherein the keyboard input information comprises: sample input device information, input character type information, and input time information; and the input character types include english, numerals, and symbols.
In specific implementation, the collection of the keyboard input information can be performed at ordinary times, for example, when an employee is on duty, after a computer is started, an input method software account provided by a company is logged in, and the keyboard input information is obtained through an input method. Each keypad entry may be a ternary data, for example (00-03-47-F6-68-31, english, 2020.01.01.16.23), indicating the mac address of the input device, the type of character entered, and the time point of entry, respectively.
Suppose that text entered by a user at a certain time is collectedtFor sda12346316sda123, a total of 17 characters will generate the corresponding 17 aforementioned keyboard input information sets in turn, i.e. a chinese charactert 1 ，t 2 ，…，t 17 And continuously collecting a large amount of keyboard input information.
However, the collected keyboard input information may be very noisy, and not all data is suitable for subsequent analysis and calculation, so that the collected keyboard input information needs to be classified and extracted.
S1.1.3, screening out the number of continuous input numeric characters exceedingkKeyboard input information that matches the current input device information and the sample input device information.
Wherein the content of the first and second substances,kthe default value is mainly to avoid the password being shorter than the cipher code due to the conferencekThe bit-induced decipherability of the incoming cipher is increased. For examplekAnd (6). Matching the current input device information with the sample input device information primarily takes into account differences in typing frequencies caused by different input devices. For example: the virtual keyboard typing speed and the physical keyboard typing speed on the touch screen equipment are greatly different, and whether the physical keyboard comprises a digital area or not is influenced to a certain degree.
Taking the input text "sda 12346316sda 123" as an example,kwhen =6, only the set of digits "12346316" needs to be retained, the preceding and following "sda" being discarded because the character type is not a digit, while the following "123" being discarded because the length is less than 6.
Of course, noise reduction may be further achieved, for example, by discarding more frequently appearing combinations of digits based on keyboard input information, because more frequently appearing combinations of digits may be a common account number or password, and typing may be faster than entering a password.
S1.1.4, calculating average input frequency based on the number of numeric characters and the input time interval as typing frequency information.
As described in the above example, after the screening, the group of numbers "12346316" is obtained, and the time Δ required for inputting the group of numbers can be calculated from the input time information in the keyboard input information corresponding to the group of numberstAnd calculating the input frequency corresponding to the text segment according to the number of the charactersfThe average typing frequency can be further calculated through a large amount of texts and used as typing frequency information.
S1.2, based oniGenerating typing frequency information of each expected participantn i A digit of an access code, whereini∈I,And isIRepresenting the total number of expected participants. I.e. the password for each intended participant is generated independently.
In order to set the length more accurately when generating the session password, the influence of different hardware and software environments, such as response delay between the input start and the start of face recognition, which mainly includes input delay and program running delay, can be further considered, and the input delay refers to the time when the user inputs to the device response, which is influenced by hardware and software. The program running delay refers to the time from starting to running of the facial recognition program, which is mainly influenced by the facial recognition algorithm and the hardware environment for the algorithm running and needs to be measured and acquired in advance.
Meanwhile, the video length of the face recognition needs to be kept for a certain time, and the value of the video length is influenced by different hardware environments, and is assumed to be 2 seconds. This time needs to be taken into account when setting the password.
Thus, the base is based oniGenerating typing frequency information of each expected participantn i A bit session password comprising:
s1.2.1, generating an inclusionkA pad segment cipher of digit numbers; and iskIs a preset value; can be directly generated randomly.
S1.2.2 generating a package based on response delay and typing frequency informationn i1 A first buffer cipher of digit numbers; the response delay is the time required from the start of input to the start of face recognition. The first buffer is obtained by multiplicationAnd the length of the section of the password is punched, and the password with the corresponding length is randomly generated to be used as the first buffer section password.
S1.2.3 generating a package based on facial recognition duration and typing frequency informationn i2 A second buffer of digit codes. The length of the second buffer section password can be obtained by multiplication, and then the password with the corresponding length is randomly generated to be used as the second buffer section password.
Combining the first buffer segment password, the second buffer segment password and the filling segment password to obtainn i The access code of the bit is encrypted,n i =n i1+ n i2+ k。
after the conference-entering password is generated, the corresponding predicted conference participants can be notified of the conference-entering password, and the specific method can be that the conference-entering password is pushed to online communication software accounts of the predicted conference participants.
And S2, acquiring the face information of the expected participant as the expected participant face.
In specific implementation, the face recognition attendance system of a company can be accessed, and the expected face of the participant can be imported through manual selection. Facial information for each employee may also be collected independently.
And S3, when the conference password is input on the participant terminal, acquiring the image before the conference in front of the screen of the participant terminal.
In specific implementation, the participating terminal can be a computer, a mobile phone, a tablet and other equipment provided with teleconferencing software for executing the method, so that the image before meeting can be acquired through a camera device connected with the equipment.
And S4, recognizing the face in the image before meeting, and marking the recognized face information as the actual meeting face.
In particular, the face recognition process may be performed at the participant terminal.
And S5, matching the actual face of the participant with the expected face of the participant, and if the actual face of the participant is not successfully matched with the expected face of the participant, indicating that the person who inputs the conference password does not belong to the expected participant, so that a warning for leakage of the conference password is given. The specific early warning method can be a mode of canceling the authority, closing the conference, notifying a manager and the like.
