In particular, the available hardware is the hardware that is present on the device. The available hardware for different devices may not be the same. For example, some computers have front-facing cameras, while some computers do not. In addition to the types of hardware listed above, the available hardware may also include fingerprint recognition devices, iris recognition devices, and the like.
Preferably, providing authentication services to a user based on the type of device and available hardware includes:
acquiring a corresponding identity verification mode based on the type of the equipment and available hardware;
and authenticating the user based on the authentication mode, and judging whether the user has the authority of collaborative making.
Specifically, the identity verification mode is obtained by selecting based on comprehensive consideration of the type of the equipment and available hardware, and the most convenient identity verification mode is obtained.
Preferably, the acquiring the corresponding authentication mode based on the type of the device and available hardware includes:
if the type of the equipment is a mobile phone or a tablet or a computer and the available hardware comprises a front camera, the identity authentication mode is face recognition authentication;
if the type of the equipment is a mobile phone or a tablet or a computer and the available hardware does not comprise a front-end camera, the identity authentication mode is account password authentication.
In particular, compared with the verification mode of the account password, the verification mode of the face recognition is higher in convenience, so that when the front-facing camera is detected to be arranged on equipment used by a user, the face recognition is adopted for recognition.
Preferably, the identity recognition module comprises a storage unit and a face recognition unit;
the storage unit is used for storing the identity verification information of all users with collaborative making authority, wherein the identity verification information comprises an account number, a password, a face image and user information;
the face recognition unit is used for carrying out identity authentication on the user in a face recognition authentication mode.
Preferably, the authentication of the user by adopting a face recognition authentication mode comprises the following steps:
and acquiring a face image of the user, and comparing the face image with the face image in the storage unit, so as to determine whether the user has the collaborative making authority.
Preferably, acquiring a face image of a user includes:
continuously shooting the face of the user to obtain a face image set Q;
and calculating the face image set Q to obtain a face image of the user.
Specifically, continuous shooting can obtain face images of a plurality of users in a short time. The image most conforming to the set condition can be selected as the final face image by calculating the set Q. Compared with a single shooting mode, the method and the device can improve the probability of obtaining the face image with high quality, so that the probability of obtaining a correct verification result by a user for single identity verification is improved, and the user experience is improved.
Preferably, shooting the face of the user continuously to obtain a face image set Q includes:
calculating the offset coefficient of the face image once every fixed number of sheets;
if the offset coefficient of the face image is larger than the set coefficient threshold or the accumulated duration of continuous shooting reaches the set duration threshold, stopping shooting to obtain a face image set Q.
Specifically, there are two end conditions for continuous shooting in the present invention, and any trigger stops shooting. The first end condition is that the accumulated time length reaches a set time length threshold value, which is a condition for ending continuous shooting in a relatively conventional way. The second end is that the offset coefficient is larger than the set coefficient threshold, and because the head of the user may move slightly in the continuous shooting process, the continuous shooting can be stopped when the moving amplitude is larger by using the offset coefficient, and the invention further needs to calculate the images in the set Q, if the amplitude is too large, the acquisition of the detection area in the process of calculating the set Q cannot be smoothly performed, so that the face image of the user is not beneficial to being obtained from the set Q quickly.
Preferably, the offset coefficient of the face image is calculated once every fixed number of sheets, including:
in the formula (i),for the offset coefficient of the t-th face image, < >>The center coordinates of the detection area of the t-th face image; />Is the center coordinates of the detection area of the first face image.
Specifically, the fixed number of sheets may be 3 sheets, 4 sheets, 5 sheets, etc., and specific numerical values may be set according to actual situations. The offset coefficient is mainly obtained by calculating the change between the center coordinates of the detection areas of the two face images, and the larger the offset coefficient is, the larger the amplitude of the head movement of the user is, and the larger the shooting ending probability is. The offset coefficient is calculated after the fixed number of sheets is set, so that the offset coefficient has enough calculation time to calculate, the calculation pressure is reduced, and the offset of the head of the user is generally smaller between two adjacent face images, so that the continuous shooting can be stopped in time by the fixed number of sheets.
Preferably, the method for acquiring the detection area of the first face image includes:
for the first face imagePartitioning is performed, will->Dividing the space into K rectangular areas with the same area;
calculating a representative coefficient of each region belonging to the face part of the user;
wherein, the calculation function of the representative coefficient is:
representing coefficient of region d represented in human face part of user, < ->Representing the ratio value->,For the set of other regions adjacent to region d, +.>Variance of gray value for pixel in region k +.>Is the variance of the gray value of the pixel in region d +.>Variance of gradient value for pixel point in region k +.>Variance of gradient values for pixel points in region d; n is->The number of regions in (a);
and taking the area with the largest representative coefficient as a detection area of the first face image.
Since the face region needs to be identified later, the present aspect only calculates the representative coefficient for the region belonging to the face portion of the user, thereby improving the efficiency of acquiring the detection region. Specifically, if a region includes pixels of a skin portion of a face, the region is a region belonging to the face portion of the user. The detection region is obtained for calculating the offset coefficient, so that the invention respectively carries out comprehensive calculation from the variance of the gray value and the variance of the gradient value to obtain the representative coefficient, and if the difference between one region and the surrounding region in terms of the gray value variance and the gradient value variance is larger, the representativeness of the region is better. And after the area with the best representativeness is selected, the detection area can be obtained quickly and accurately when the detection area is extracted from other face images. Because if the representativeness is small, the detection area of other face images is difficult to obtain, that is, a plurality of windows to be screened with very high similarity may exist in a plurality of windows to be screened obtained by taking the window to be screened as the center of the sliding window, so that the offset coefficient cannot be accurately and rapidly calculated.
Preferably, the method for acquiring the detection area of the t-th face image includes:
for the t-th face imagePerforming image difference processing to obtain the t-th face image and +.>Total number of pixels with different gray values +.>;
Calculating a variation coefficient:
calculating the radius:
wherein,,for the radius used when the acquisition of the detection area is performed in the t-th face image,the maximum value of the side length of the detection area of the first face image; />The total number of pixel points in the t-th face image;
using pairs of windows of the same size as the detection area of the first face imageIs the center of a circle>Sliding window detection is carried out for the pixel points within the radius range, so that a plurality of windows to be screened are obtained;
and respectively calculating the similarity between each window to be screened and the detection area of the first face image, wherein the pixel point corresponding to the window to be screened with the highest similarity is used as the pixel point of the detection area of the t-th face image.
For the t-th face image, the change range of the central pixel point of the window to be screened is obtained through the change coefficient and the radius, and the radius can be increased along with the increase of the change coefficient by the arrangement mode, so that the situation that too many windows to be screened are obtained when the change coefficient is smaller is avoided, and the calculation pressure is reduced. The radius can be changed along with the change, so that the method does not need to set the change range of the central pixel point of the window to be screened in advance, thereby reducing the implementation difficulty of the method and improving the adaptability of the method.
Preferably, as shown in fig. 2, the face image set Q is calculated to obtain a face image of a user, including:
calculating the competitiveness coefficient of each face image in the face image set Q based on the calculation region respectively;
and taking the face image with the largest competitive coefficient as the face image of the user.
Specifically, the competitiveness is not calculated according to the attributes of all the pixels, but calculated according to the calculation region. The efficiency of obtaining the face image of the user from the set Q can be improved.
Acquiring the distance between the region with the representative coefficient and the regionAnd->The sum of the distances between is the largestZone->;
Specifically, the calculated area is obtained by calculating the distance between the representative coefficient and the area, firstly obtaining the most representative area by the representative coefficient, and then selecting the distanceThe furthest area with the representative coefficient and finally the area with the largest distance between the two areas selected before are selected, and the selection mode ensures that the calculation area comprises representative pixel points and range pixel points, so that the competitiveness of the face part of the face image is comprehensively represented from two different aspects.
Preferably, the calculation function of the competitiveness coefficient is:
in the function of the method,is the competitive coefficient of the face image q, < +.>Is->、/>And->Set of->And->Respectively calculating the minimum and maximum values of the gray values in region j, +.>Is the total number of pixel points with gray value of i, < >>To calculate the total number of pixels in region j.
The competition coefficient is calculated by the accumulated sum of the probabilities of different gray values of the pixel points in the three areas, and the larger the accumulated sum of the probabilities of different gray values is, the larger the competition coefficient is, the more abundant the image details in the face image are, so that the face image with the most abundant image details in the set Q is selected as the face image of the user.
Preferably, the identity recognition module further comprises an account password recognition unit;
the account password identification unit is used for carrying out authentication on the user in an account password authentication mode.
Specifically, the account password identification unit is used for acquiring an account and a password input by a user, and comparing the account and the password input by the user with the account and the password stored in the storage unit, so as to determine whether the user has collaborative making permission.
Preferably, the cloud server is further configured to store editing rights of each user to the target document.
Specifically, for the same target document, different editing authorities can be set for different users, for example, a certain user can be limited to only view the target document and not edit the target document; the range of pages that the user can edit may be limited.
Preferably, the editing module comprises an input unit, a downloading unit, an editing unit and an uploading unit;
