    [0002] Identification of high performance passengers in the entrance supervision

    [0004] BACKGROUND OF THE INVENTION
    [0005]
    [0006] Field of the Invention
    [0007]
    [0008] [0001] The present invention relates to the field of access control and entry security and more particularly to the identification with automated machines of a passenger.
    [0009]
    [0010] Description of the related technique
    [0011]
    [0012] [0002] Entry security refers to determining whether or not an individual is authorized to pass through an entrance to a security zone. Usually, entry security refers to the context of determining whether or not an individual is authorized to enter a transport terminal or a vehicle, or a building security zone or even a meeting area such as a concert hall public or sports facilities. Normally, entry security is a manual process that involves manual inspection by a security agent of an individual requesting to pass through an entry zone. The individual provides some type of documentation regarding the identity of the individual and the security agent attempts to validate the authenticity of the documentation.
    [0013]
    [0014] [0003] Biometrics contributes to entry security in many circumstances. In an environment where the possible number of individuals authorized to access a security zone is reduced, a database of biometric information for each individual can be maintained at the entrance so that the biometric scanning of one of the Individuals can be compared with the known records of the limited number of individuals authorized to pass through entry security. However, for groups of more numerous individuals who potentially request to enter a security zone, it may not be feasible to know a priori biometric information for each possible individual. In the latter circumstance, either the biometric information must be stored in relation to a credential provided by the individual to the security agent when requesting to enter through an entry security, or the biometric information can be used only to document the fact that The individual has requested access to the security zone.
    [0015]
    [0016] [0004] Recently, biometrics has begun to play a more important role in entry security; especially in the context of airport security.
    [0017] Publicly, different governments around the world have implemented biometric entry security measures in which individual travelers previously register biometric information such as fingerprints or information for the iris scanner. Then, when requesting access through an entrance to a security zone, the individual can undergo a biometric scanner in a kiosk in conjunction with the presentation of paper credentials. However, although biometrics is faster than the traditional manual inspection of an individual in an entry security, there is still a queue to access a limited set of kiosks adapted for a biometric scanner. In considerable high-performance environments such as modern cruise ships, the individual use of a kiosk can remain burdensome and inefficient.

    [0019] BRIEF SUMMARY OF THE INVENTION
    [0020]
    [0021] [0005] The embodiments of the present invention address the shortcomings of the technique in relation to entry security and provide a new and non-obvious method, system and software product for identification of high performance passengers in security input In one embodiment of the invention, a data processing system is adapted for the identification of high performance passengers in entry security. The system includes a central computer system of at least one processor and one memory, an imaging device communicatively linked to the central computer system and arranged in an entry passage leading to a security zone, a display coupled to the system central computer and located in the entrance passage, a face database coupled to the central computer system, and a high-performance passenger identification module.
    [0022]
    [0023] [0006] The module includes computer program instructions running on the central computer system. The program instructions are capable of receiving from the imaging device an image obtained simultaneously from a group of individuals approaching the entrance passage, to identify a set of faces of the group of individuals in the image obtained simultaneously and to consult the base of data with each identified face of the set and for each face assign a confidence value of having corresponded the face with a record of a known person in the database; The program instructions are also capable of visually decorating each face of the image obtained simultaneously with an initial visual characteristic, such as a red outline, provided that a correspondingly assigned confidence value is below a threshold, but with a different visual characteristic, such as a green outline, provided that the correspondingly assigned confidence value is not below the threshold. Finally, the program instructions are capable of displaying the image obtained simultaneously in the display.
    [0024]
    [0025] [0007] In one aspect of the embodiment, the program instructions are also capable of receiving from the imaging device an image subsequently obtained from the group of individuals approaching the entrance passage, to identify the set of faces of the group of individuals of the image obtained simultaneously in the image obtained subsequently and to filter the set in order to include only those faces of the set that have a previously assigned confidence value but correspondingly from the image obtained simultaneously that is by below the threshold. The program instructions are also able to visually decorate each filtered face from among the set of the image obtained simultaneously with the different visual characteristic and then consult the database with each face that remains in the filtered set. For each face that remains in the filtered set, a new confidence value is assigned if the face has been matched with a record of a known person in the database and each face of the image subsequently obtained from the filtered set is visually decorated with the initial visual characteristic with the condition that the new confidence value assigned correspondingly is below the threshold, but with the different visual characteristic provided that the new confidence value assigned correspondingly is not below the threshold. Finally, the image obtained later is displayed on the display instead of the image obtained simultaneously.
    [0026]
    [0027] [0008] In another additional aspect of the embodiment, the program instructions are also capable of receiving from the imaging device an additional image subsequently obtained from the group of individuals approaching the entrance passage, and identifying a new set of faces of the group of individuals from a previously obtained image more recently in the image subsequently obtained additionally. Then, the new set is filtered to include only those faces of the new set that have a previously assigned confidence value but correspondingly from a previously obtained image that is below threshold. Therefore, each filtered face from among the new set is visually decorated with the different visual characteristic and the database is consulted with each face of the new filtered set. For each face of the new filtered set, a new confidence value is assigned if the face has been matched with a record of a known person in the database and each face of the additionally obtained image of the new filtered set is visually decorated with a new visual feature with the provided that the additional confidence value assigned correspondingly is below threshold, but with the different visual characteristic with the condition that the additional confidence value assigned correspondingly is not below threshold. Finally, the additional image subsequently obtained is displayed on the display instead of the image obtained simultaneously.
    [0028]
    [0029] [0009] In another embodiment of the invention, a method is provided for the identification of high performance passengers in an entry security. The method includes receiving in a memory of the central computer system from an imaging device an image obtained simultaneously from a group of individuals approaching the entry passage. The method also includes identifying a set of faces of the group of individuals in the image obtained simultaneously. The method additionally includes consulting a database of faces with each face identified in the set and for each face assigning a confidence value of having corresponded the face with a record of a known person in the database. Finally, the method includes visually decorating each face of the image obtained simultaneously with an initial visual characteristic with the condition that a correspondingly assigned confidence value is below a threshold, but with a different visual characteristic provided that the correspondingly assigned confidence value is not below the threshold; and display the image obtained simultaneously in a central computer system display.

    [0042] DETAILED DESCRIPTION OF THE INVENTION
    [0043]
    [0044] [0012] The embodiments of the invention contemplate a high performance passenger identification in an entry security. In accordance with an embodiment of the invention, an imaging device disposed in an input passage repeatedly captures an image sequence of groups of individuals as the groups approach the input passage. Each image of the sequence is then presented in order in a display in the entry passage so that each individual in an approaching group can observe images of the group as the group approaches the entry passage. For each image of the sequence, different faces are identified in the captured image and each of the different faces is decorated in the image shown and presented on the display so that the individuals in the approaching group are familiar with a process of mass facial recognition. In this regard, each of the different faces of each image captured in the sequence is compared separately with a database of known faces authorized to pass through the entry passage.
    [0045]
    [0046] [0013] A match of each of the faces is carried out in front of the database, assigning to each match a specific level of confidence indicating a degree of confidence in which a corresponding face of the captured image coincides with a face specific to the database. With respect to each image captured in the sequence, for faces that have a lower confidence level than a threshold value, the face decoration presented on the display has a visual form, for example, a red square surrounding the face. But for faces that have a confidence level higher than a threshold value, the Face decoration is presented on the display with a different visual form, for example, a green square surrounding the face. In this way, multiple different individuals can be processed at once while they pass through the entrance passage and when the faces of each image captured in the sequence correspond to a confidence beyond a threshold value, the decoration for each of the faces As presented on the display, you can change from the initial visual form to the different visual form. Likewise, each individual in the approaching group was presented with feedback as to whether or not it is permissible to advance through the entry passage.
    [0047]
    [0048] [0014] In additional illustrations, Figure 1 graphically shows a process for the identification of high performance passengers in an entry security. As shown in Figure 1, a group 150 of individuals 150A, 150B, 150C approximates an entry passage 100 within the field of view 110 of an imaging device 120 of one or more imaging sensors located near the entrance passage 100. The imaging device 120 obtains a sequence of different images 130, each of the images 130 of the sequence including images of each of the individuals 150A, 150B, 150C. A face is identified for each of the individuals 150A, 150B, 150C in the image 130 and each is provided as a facial recognition query 170 to a database of faces 180 correlating different faces with different identifying information for different individuals.
    [0049]
    [0050] [0015] In response to the facial recognition query 170, different matches 190 are returned that include different confidence values. Each confidence value indicates a degree of confidence for which a corresponding face matches an entry in the face database 180. The high-performance passenger identification logic 140 compares the confidence value for each of the faces of the matches 190 with a predetermined threshold 175. For each face of the matches 190 having a confidence value that is below the threshold 175, the high performance passenger identification logic 140 decorates a corresponding face in the image 130 using a type of visual feature 160 as a red square outlining the corresponding face. However, for each face of the matches 190 that has a confidence value that is not below threshold 174, the high-performance passenger identification logic 140 decorates a corresponding face in the image 130 using a different type of visual feature. 160, like a green square outlining the corresponding one. Then the logic High performance passenger identification 140 presents the image 130 in a display 165 located near the entrance passage 100.
    [0051]
    [0052] [0016] The process described in relation to Figure 1 can be implemented in a data processing system and, by way of example, in connection with an entry passage for passengers entering a vehicle such as a ship, bus, train or airplane. In additional illustrations, Figure 2 schematically shows a data processing system adapted for the identification of high performance passengers in an entry security. The system includes a central computer system 210 with memory and at least one processor communicatively coupled by a computer communications network 220 with one or more image sensors 230 of an imaging device, located sequentially towards a passage input and adapted to obtain different image frames and to transmit the image frames obtained to the central computer system 210. The system also includes a high performance passenger identification module 300.
    [0053]
    [0054] [0017] The high performance passenger identification module 300 includes program instructions that when executed in the memory of the central computer system 210 can receive an image obtained from one of the image sensors 230 and identify different faces of different individuals respectively in the image obtained using a facial recognition interface 250. The program instructions can additionally compare the faces identified with face images in the face database 240 in order to produce a set of matches for each of the faces , including each match a corresponding confidence value. The program instructions are also capable of determining which faces of the image obtained have matched corresponding face images of the face database 240 with a degree of confidence according to the confidence value that is not below a previously stored threshold. , and which faces of the image obtained have matched corresponding face images in the face database 240 with a degree of confidence that is below a previously stored threshold.
    [0055]
    [0056] [0018] For those faces of the image that the high performance passenger identification module 300 has determined to have a confidence value that is not below the previously stored threshold, the program instructions decorate the corresponding face in the image of according to a visual feature like a red eyeliner around the face of the image. On the other hand, for those faces of the image that a high performance passenger identification module 300 has determined to have a confidence value that is not below the previously stored threshold, the program instructions decorate the corresponding face in the image according to a different visual feature like a green outline around the face of the image. Finally, the program instructions show the image with the faces decorated in a display 260 located near the entrance passage.
    [0057]
    [0058] [0019] In addition, in a further illustration of the operation of the passenger identification module 300, Figure 3 is a flow chart illustrating a process for the identification of high performance passengers in an entry security. Starting at block 310, a group of different passengers approaching an entry passage is detected and an image of the group is obtained, for example by means of an image sensor between multiple image sensors. In block 330, each face of the image is identified and stored in a series of faces for the image. Then, in decision block 340, it is determined whether an image previously obtained by another or by the same image sensor has already been processed to produce the series of faces. If so, in block 350 the series of faces is filtered to exclude any face already processed in order to have a corresponding correspondence trust value that is not below a predetermined threshold.
    [0059]
    [0060] [0020] Then, in block 360, a database of faces is consulted with the remaining faces of the series of faces to extract, in block 370, a respective correspondence confidence value for each face of the series. In block 380, a first face of the series is selected and in a decision block 390, it is determined whether or not a respective correspondence trust value is below the predetermined threshold. If not, a decoration is drawn on the image as a green contour around the face. On the other hand, in decision block 410, it is determined whether an alert condition has been established or not; specifically, whether or not the image reflects a proximity to the entrance passage leaving a little time before the group of passengers crossed the entrance passage. In that case, a decoration is drawn on the image as an intermittent red contour around the face in block 430.
    [0061]
    [0062] [0021] Optionally, to the extent that the image reflects a proximity to the entrance passage left a short time before the passenger group crossed the entrance passage, an alert message can be transmitted to a mobile device of a door agent located near the entrance passage, for example to a tablet. To the extent that the tablet has a common wireless network connection to the central computer system that hosts the passenger identification module in order to form an intranet, the alert can be transmitted as a message on the intranet at a speed much greater than a message transmitted through multiple different networks through different gateways. In any case, to the extent that the alert condition has not been established, only a solid red outline is drawn on block 420 around the face in the image. In any circumstance, in decision block 440, it is determined whether or not additional faces remain in the series. In this case, the process would be repeated through block 380. Otherwise, in block 450 the image would then be displayed on a screen near the entrance passage.
