4) Face recognition is a biometric technology for identity recognition based on facial feature information of a person. A series of related technologies, which are generally called face recognition and face recognition, collect images or video streams containing faces by using a camera or a video camera, automatically detect and track faces in the images, and then perform face recognition on the detected faces.

An exemplary application of the self-service printing system provided by the embodiment of the present application is described below, wherein the terminal in the system provided by the embodiment of the present application may be implemented as various types of authority identification devices such as a notebook computer with an image capturing function, a tablet computer, a desktop computer, a mobile device (e.g., a personal digital assistant, a dedicated messaging device), and the like.

Fig. 1A is a schematic flow chart of an implementation process of a self-service printing method provided in an embodiment of the present application, and as shown in fig. 1A, the method includes:

s101, responding to a triggered self-service printing service event, and collecting a first biological characteristic of a target user;

in implementations, the biometric characteristic includes at least one of: face information, fingerprint information, voiceprint information, iris information, and finger vein information.

The face information may be considered as a biological feature, and the biological feature may include face information, fingerprint information, voiceprint information, iris information, finger vein information, and the like, in other words, the printing manner based on face brushing may be understood as a printing manner based on biological feature. Based on this, the face recognition device may be understood as an electronic device that performs biometric recognition (referred to simply as a biometric recognition device), in other words, the biometric recognition device may include a face recognition device, a fingerprint recognition device, a voiceprint recognition device, an iris recognition device, a finger vein recognition device, and the like. Biometric devices are generally portable mobile electronic devices, taking into account factors such as ease of installation.

In some embodiments, taking the collected biometric features as the face information as an example, a binocular camera may be disposed on the biometric recognition device connected to the printing device.

In some embodiments, the biometric device has the capability to collect and compare fingerprint information, voiceprint information, iris information, and finger vein information.

Step S102, in response to the situation that the first biological characteristics are not successfully compared with the pre-stored biological characteristics, obtaining a target user account to be associated;

in some embodiments, the pre-stored biometric characteristic may be obtained from a set of biometric characteristics stored in the biometric characteristic recognition device, or may be obtained from a set of biometric characteristics stored in the background of the biometric characteristic recognition device. At least two pairs of association relations between the biological characteristics and the user account are stored in the biological characteristic set.

In the implementation process, in response to the situation that the first biometric characteristic is not successfully compared with the pre-stored biometric characteristic, that is, the first biometric characteristic is not stored in the biometric characteristic set, the first biometric characteristic needs to be matched with the user account number to be printed for storage. And matching the corresponding user account to acquire a target user account to be associated.

In some embodiments, the user may manually output his account on a display screen of the biometric device, so that the biometric device obtains the target user account to be associated.

In other embodiments, the biometric device may obtain the target user account to be associated by recognizing information of the user identity card.

Step S103, in response to the condition that the target user account is verified to be valid, associating the target biological characteristics of the target user with the target user account to obtain an association relationship, and storing the association relationship; wherein the target biometric comprises the first biometric or a second biometric of the target user that is re-acquired.

In the implementation process, two methods for acquiring the target biological characteristics are provided, including a method I and a method II:

in the first method, when the first biological characteristic (acquired by the biological characteristic recognition device for the first time) meets the association requirement (that is, the biological characteristic required by the association with the target user account is met, which may be understood as a second preset condition below), the first biological characteristic acquired for the first time may be directly used as the target biological characteristic of the target user, and the first biological characteristic and the target user account are associated to obtain an association relationship and store the association relationship.

In the second method, in the case that the first biometric characteristic does not meet the association requirement, for example, in the case that the integrity and/or the clarity of the first biometric characteristic does not meet the requirement, the second biometric characteristic meeting the association requirement needs to be acquired for the second time, and in the acquisition process, the biometric recognition device may give some methods for adjusting the acquisition to the user so that the acquired second biometric characteristic meets the association requirement. And under the condition that the second biological characteristics acquired for the second time meet the association requirements, taking the second biological characteristics as target biological characteristics, associating the second biological characteristics with the target user account to obtain an association relationship, and storing the association relationship.

In some embodiments, after the storage of the association relationship is completed, if the user needs to print a file, the biometric feature of the target user needs to be acquired for the third time, the biometric feature is compared with the stored biometric features preset in the biometric feature set, and the printing is performed under the condition that the comparison is successful. Here, the third biometric integrity and clarity of the third acquisition may be lower than the target biometric.

In the embodiment of the application, the user uses the printer for the first time, the biological characteristics can be automatically input into the biological characteristic recognition device, the association between the biological characteristics and the user account is completed, and the association relation is stored. Therefore, the biological characteristics are automatically input by the biological characteristic recognition equipment without the intervention of an administrator, and the biological characteristics are automatically input and bound with the user account in an integrated manner, so that the biological characteristic recognition equipment is convenient and quick. Therefore, the problem that the workload of the common face brushing printer for operating a system administrator is large, when personnel information is newly added/changed, a user needs to send own photos to the system administrator, and if the photos do not accord with the identification standard, the process is repeated and tedious is solved.
