In order to overcome the problem that the prior art event cannot effectively identify visitors and cannot accurately and actively send data to specific visitors, or interact with specific visitors, the present invention uses the technology of identifying visitors’ biological characteristics to compare the biological characteristics with Or it may not be linked to the visitor's personal data, but accurately and proactively provide information to specific users in specific areas.

The first embodiment:

Please refer to Fig. 1, which is a schematic diagram of a system for recognizing facial features and actively providing services according to the first embodiment of the present invention. In Figure 1, system 1 includes processor 2, and processor 2 The first camera device 3, the barcode scanning device 4, the second camera device 6, the transceiver 9 and the database 5 are coupled or electrically connected, wherein the first camera device 3 and the barcode scanning device 4 are set in the first event In area 11, the second camera device 6 is set in the second area 12 of the event. The database 5 and the processor 2 can be integrated in a server 8. The first area 11 of the event event is usually the registration and/or registration area of the event event. The organizer of the event event handles the registration or registration and registration of multiple users A and B in the first area 11. Those with ordinary knowledge in the technical field can know that users A and B are only examples, and they are not limited to two users, and may actually include more users.

The personal data of users A and B include, but are not limited to, the data receiving URL, ID card number, birthday, phone number, and user A, B’s event of the event, and the data receiving URL is converted into a code. Each user A The barcodes of B and B are stored in the database, and the barcodes can be printed on a carrier (such as paper products) or digitally presented on the screen of the user's electronic device. Users A and B can provide their personal information to the organizer of the event in a digital or analog way before they appear in the first area 11, or they can digitally or analogously provide them when they appear in the first area 11. Personal information is provided to the organizer of the event to complete the registration and registration procedures. These analog personal data will be converted into a digital format and stored in database 5, which stores the personal data of all users who have completed the registration process.

Please refer to Figure 1 and Figure 2 together. When users A and B report in the first area 11, the first camera device 3 captures the first facial images 14 of users A and B, and the processor 2 analyzes The first facial image 14 recognizes at least one first facial feature 15, and the first facial feature 15 is stored in the database 5. At this time, the processor 2 associates at least one first facial feature 15 of the user A with his personal data 16 and assigns a number, for example, the user A obtains the number 123. In the same way, user B obtains the number 456. These numbers are also stored in database 5. After users A and B obtain the serial number, they will complete the registration and check-in procedures for the event.

Please refer to Figure 1 and Figure 3 together. When User A starts from an event (e.g. exhibition When the first area 11 (for example, the check-in area) of the conference) enters the second area 12 (for example, a booth), the second camera device 6 captures the second facial image 18 of the user A, and the processor 2 analyzes the second face The image 18 is used to identify at least one second facial feature 19, and the at least one second facial feature 19 is combined with the facial feature set 20 of the database 5 (that is, all the first facial features 15, 15a, 15b) For comparison, the first facial features 15a, 15b, etc. are the first facial features of other users. When at least one first facial feature 15 matching at least one second facial feature 19 is compared, it indicates that user A has participated in the activity of the second area 12 and obtained the child activity related to the child activity event of the second area 12 Therefore, the processor 2 provides the user A with sub-activity data related to the sub-activity event in the second area 12 according to the number pointed to by the first facial feature 15.

The processor 2 of the present invention analyzes the first facial image 14 to recognize at least one first facial feature 15, and analyzes the second facial image 18 to recognize at least one second facial feature 19, including but not limited to the face Image acquisition, face positioning, face recognition pre-processing, face attribute extraction and other technologies are completed. Even the deep neural network algorithm of artificial intelligence can be used to improve the correct recognition rate of facial features in facial images of all users.

An event usually has a plurality of second areas (such as booths, seminars, exhibition areas, etc.), but not any user is interested in each second area or not any user has permission to enter each second area area. Therefore, the user’s personal data further includes at least one point of interest option, the at least one point of interest option indicates whether the user is interested in a specific second area, and the selection result of the at least one point of interest option (for example, for visiting the second The selection of area 12 is yes or no) and other personal data are stored in the database 5. Taking the second area 12 in Figure 1 as an example, when the personal data of the user A includes the option of selecting the second area 12 as a point of interest, and the user A passes the facial feature comparison in the second area 12, the processor 2 Retrieve user A’s points of interest option content from the database 5 to determine that user A does have the authority to participate in the activities of the second area 12 and obtain the child activity data related to the child activity events of the second area 12, and issue the first Second zone 12 The sub-activity data of is provided to user A to avoid mistakenly allowing users who do not have the permission to participate in the second area 12 to enter the second area 12 and obtain the sub-activity data due to the possible error rate of facial feature comparison.

In another scenario, if the personal data of user A does not include the option of selecting the second area 12 as a point of interest, even if the user A passes the facial feature comparison in the second area 12, the processor 2 retrieves data from the database 5. Retrieving the content of user A’s points of interest options will deny user A’s participation in the activities of the second area 12 and deny user A the right to obtain the child activity data related to the child activity events of the second area 12, thus the second area The child’s activity data was not sent to user A.

As shown in Figure 1, the processor 2 transmits the sub-event data to the second area 12 through the transmitter 9, the electronic device 7 belonging to the organizer of the event or the organizer of the second area, through the multimedia interface of the electronic device 7. (Such as a screen and a sound player, not shown in Figure 1) and provide the user A with the sub-activity data.

Or, as shown in Figure 4, the sub-activity data 13d is stored in the directory 13b and sub-directory 13c of the hyperfile transfer protocol (http, data receiving URL) 13a exclusive to user A (number 123) in the database 5. Next, user A installs a software or web browser that can log in to the data receiving URL or a software or web browser that does not need to log in to his personal data on his mobile device 10, and executes the software or web browser to read and sub-event events Related sub-activity data 13d. After user A with the number 123 passes the biometric identification, analysis, comparison, and point of interest options in Booth 2, User A can also read information related to the sub-event event (Booth 2) from the directory 13b and sub-directory 13e Sub-activity data 13f.

In the first embodiment, by comparing the user’s second facial feature with the first facial feature stored in the database in the second area, the organizer of the sub-event event can also count which users enter this second area. Area, automatic data exchange with the user who selected the specific second area as the point of interest option in advance. In addition to the processor 2 actively providing the sub-activity data related to the sub-activity event to users who are allowed to enter the second area, the processor 2 can also send electronic questionnaires, electronic gift certificates, prize redemption coupons, etc. related to the sub-activity event. To the user.

As shown in Figure 5, the personal data, first facial features, and barcode numbers and information of the first embodiment are stored in the personal data storage module 5a, facial feature storage module 5b, and barcode storage of the database 5, respectively In the module 5c, the processor 2 coupled to the database 5 retrieves the data of the modules 5a, 5b, and 5c of the database 5 for comparison or analysis.

Therefore, in the first embodiment of the present invention, by associating the user’s first facial feature with his personal data and obtaining a number, the user can complete the registration procedure for the user’s participation in the event. In the area of the event, the user’s second facial feature is compared with the first facial features of all users in the database, and after the comparison is matched, the sub-activity related to the sub-activity event will be determined according to the number The information is provided to the user actively. Actively provided methods include sending to an electronic device with a multimedia interface for the sub-activity event, or sending it to the user's mobile computing device via the network.

Therefore, based on the first embodiment, the present invention can be applied to a system for recognizing the facial features of the user to check whether the user is participating in an activity. The system includes a database, a first camera device, and a database coupled to the database. And the processor of the first camera device, wherein the database contains personal data for identifying the user, the first camera device installed at the location of the activity is used to capture the user’s face image, and the processor uses the personal data The combination with the facial image confirms that the user has indeed participated in the activity.

The second embodiment:

Please refer to FIG. 6, which is a schematic diagram of a system for identifying facial features and actively providing services according to a second embodiment of the present invention. In Figure 6, the system 21 includes a processor 21, a first camera device 23 coupled or electrically connected to the processor 21, a second camera device 26, and a database 25. The first camera device 23 and the second camera device 26 are respectively set in the first area 31 of the event And the second area 32, the database 25 and the processor 21 can be integrated in a server 8. As described in the first embodiment, the first area 31 of the event event in the second embodiment is usually the area where the event event is registered and/or registered. The organizer of the event event handles multiple users C, D's registration or registration and registration two procedures. Those with ordinary knowledge in the technical field can know that the users C and D are only examples, and are not limited to two users, and may actually include more users.

In the second embodiment, the personal data of users C and D are not provided to the organizer of the event during the registration and/or check-in phase of the event. Instead, users C and D arrive at the first area of the event 11 At this time, the first camera device 23 captures its first facial feature to complete the registration and registration. Please refer to FIGS. 6 and 7 together. When users C and D report in the first area 23, the first camera device 23 captures the first facial images 34 of the users C and D, and the processor 21 analyzes The first facial image 34 recognizes at least one first facial feature 35, and stores the first facial feature 35 in the database 25, and gives users C and D a number. For example, the user C obtains a number 789. In the same way, user D gets the number 234. These numbers are also stored in database 25. After users C and D obtain the serial number, they will complete the registration and check-in procedures for the event. At this time, the organizer of the event did not know the identities of users C and D, and did not store the names, ID card numbers, birthdays, and phone numbers of users C and D, but only stored user C and D’s Facial features.

Please refer to Figure 6 and Figure 3 together. As described in the same identification and comparison method in the first embodiment, when the user D enters the first area 31 (such as the check-in area) of the event (such as the exhibition) In the second area 32 (for example, a booth), the second camera device 26 captures the second facial image of the user D, and the processor 22 analyzes the second facial image to identify at least one second facial feature, and compares at least one The second facial feature is compared with all the first facial features in the database 25. When at least one first facial feature matching at least one second facial feature is compared, it indicates that the user D has the ability to participate in the activity of the second area 32 and obtain the child activity data related to the child activity event of the second area 32 Permission, so the processor 22 actively mentions the number according to the number pointed to by the first facial feature 35 Provide the sub-activity data related to the sub-activity event of the second area 12 to the directory folder of the database 25. Similar to the method described in Figure 4, the user D in the second area 32, the first area 31, or any area other than the event, carries his own electronic device (such as a mobile phone) without logging in his personal data The application (APP) or web browser, and enter the application or web browser with its number 234 to read the sub-activity data.

Therefore, in the second embodiment of the present invention, a number can be obtained for the user by analyzing the first facial feature of the user to complete the registration procedure for the user to participate in the event. There is no personal data at this stage The collection and storage by the organizer raises users’ doubts about the security of their personal data. In order to obtain the sub-event data of different sub-event areas, users do not need to log in their personal data in the application, but enter to participate in the event. The number is sufficient, this will not cause users to worry about the security of their personal data.

Therefore, based on the second embodiment, the present invention can be applied to a service providing system, including: a server including a database and a processor, a first camera device coupled to the processor and located in the first area of the event, and A second camera device coupled to the processor and located in the second area of the event, wherein the first camera device is used to capture the first facial image of the event participant in the first area and store it in the database. The second camera device is used to capture the second facial image of the related activity participant in the second area, and compare whether the second facial feature is consistent with the first facial feature, and when they match, the processor will compare with the first facial feature. 2. Sub-activities related to the sub-events of the region are provided to the event participants.

The third embodiment:

Please refer to Fig. 8, which is a schematic diagram of a service providing system according to a third embodiment of the present invention. In Figure 8, the system 41 includes a processor 42 and a body recognition device 43 that is arranged in the first area 51 of the activity event and is coupled to the processor 42. The body recognition device 43 is used to recognize the data in the first area 51 All event participants (including event participant E), and give each event participant A participation code, which can be a barcode, a combination of numbers and letters or a code, and a password. The identity confirmation medium 44 present in the event event is for event participant E to enter the participation code. This identity confirmation medium 44 can be a medium provided by the organizer of the event event or the event participant E’s own electronic device through a cable Or a wireless network is electrically connected or coupled to the processor 42. When it is detected that the event participant E enters the participation code to match the assigned participation code, the processor 42 actively provides the event participant E with activity data related to the event.

In summary, the present invention realizes the non-intrusive registration and/or check-in procedure when the event is held, can avoid the cost of making RFID and other identity verification cards, and can actively, instantly and personally transfer the sub-event data to Digitally push to users. Since the user who has previously selected the specific second area as the point of interest option enters the specific second area, the organizer of the second area can also conduct automated data exchange with the user.

The present invention is really a difficult innovation and has deep industrial value. In addition, the present invention can be modified by persons with ordinary knowledge in the technical field, but does not deviate from the scope of protection as claimed in the attached patent scope.
