Description

FIELD OF THE INVENTION

The present invention relates to the field of conducting events such as conferences, symposiums, meetings, exhibitions, fairs, trade shows, seminars, cruises, organized travel to resorts, hands-on training courses, school site visits, plant tours, panel discussions, and executive forums etc., including various sub-events that may occur in the framework of the events such as meals, receptions, literature, concerts, movies, gifts, tournaments, banquet events, gala, food and beverage functions, live entertainment, conference proceedings, conference tote bags, snacks, golf, and commemorative conference pins. In particular, the system of the invention related to events with high levels of admittance/exit security and control of the participants.

BACKGROUND OF THE INVENTION

Current conferences, exhibitions, fairs, trade shows, seminars, cruises, organized travels to resorts, hands-on training courses, school site visits, plant tours, panel discussions, executive forums, etc., are examples of public events that sometimes are attended by many thousands of visitors, participants, or guests. Density of “population” at such events may be different from very high density at theaters, movies, etc., to lower densities at exhibitions, resorts, etc.

The structural organization and carrying on of the events may also vary in a wide range from simple one-event acts such as preview of a new movie to highly organized multiple-act events such as international conferences and trade shows with many participants that may interact in accordance with a very complicated relationship scheme.

Since Sep. 11 of 2001, security concerns have become paramount at most exhibitions so that organization of security measures at such events becomes a complicated task. (http://www.iaem.org/content/IndustryInfoNews/IntWeeklyDigest/articlesfull.asp?StoryID=140)

It is desirable to control and register actions of various participants not only for security purposes. This is necessary to simplify registration, accumulate statistical data, improve efficiency of events, prepare to future activity, eliminate hard copies and extraneous paper documents and files, prepare electronic mailing lists, reduce volume of postal mailing, etc.

Attempts have been made heretofore to improve organization of events such as conferences, meetings, seminars, etc. For example, U.S. Pat. No. 6,657,543 issued in 2003 to K. Chung describes a system and method for conducting an exhibition at which visitors visit a plurality of booths or stations. A smart tag issued each visitor includes at least an electronic memory from which information from the memory may be provided and/or information may be received and stored in the memory. Stored information may include visitor information, exhibitor information, visit information, product/service information and data items. Smart tag control units and antenna arrays at the stations communicate with the smart tags and communicate directly or indirectly with one or more processors that process the information.

However, the aforementioned patent describes the method for conducting events in a very generalized form. Furthermore, security measures are mentioned in that patent only in connection with access to the event information stored in the smart tags and recording stations and does not relate to security of admission to and exit from the event, and to control of the event per se. Furthermore, the system disclosed in the aforementioned patent does not allow current tracing of the event's participants.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a system and a method for conducting high-degree-safety events that, along with security of access to the event information, are also concentrated on measures in connection with security of admission to and exit from the event, control of the event organization and conducting, and real-time tracing of the participants at any time of the event.

A system for conducting events is based on the use of a secured contactless data interchange between secured ID cards and read/write stations. Each card is associated with an individual attendant who receives the card beforehand or at the front desk of the event. The card contains an electronic chip, which is comprised of an electrically-erasable programmable read-only memory (EEPROM) for storing information relating to a card owner, at least one event, at least one sub-event in the framework of the event, an entrance password, and an exit password. Furthermore, the card may contain a memory unit for writing/reading specific data that may be obtained at event or sub-event stations. The card also contains a digital control, a chip RF antenna with a chip interface. The digital control unit may be comprised of a control and an arithmetic logic unit, an EEPROM interface, and a coding unit. There are also anti-collision unit and an authentification unit. The card does not contain a power supply battery and is energized via the RF antenna. Each read/write station of the system contain an RF antenna for contactless interaction with the RF antenna through the inductive coupling, a power supply battery, an internal memory unit for data capture application, a real time clock, authentification unit, value block, read/write block, and an interface for data loading and unloading. Externally, the read/write station contains an LCD display and a data input keypads. The station may also have a data communication port for loading the data, e.g., from the Internet. The system is equipped with secured entrance and exit gates that are also equipped with the read/write station. All the read/write stations may be connected to a common CPU via a network for tracing the even attendants in a real time mode.

Alternatively, the central processing unit may be connected only with front-desk data-input terminals while the data exchange with the cards occurs directly at the event stations that have been pre-programmed via the central processing unit. After the registration and filling in the card, the attendant passes to the territory of the event through one of the secured entrance gates by interacting in a contactless manner with the appropriate read/write station of the entrance gate. The RF antenna of the station and the antenna of the secured ID card interact when the card approaches the station by the distance not exceeding 50 mm. In visiting the event booths the card owner participates in the event and exchanges the data with the even stations. The data are stored in the event stations and can be used later for statistical processing, preparation of future mailing lists, or for security purposes, if necessary to identify the visitors, and to trace their location at any moment of presence at the event, and if necessary, at a sub-event. For exiting the event, the participant has to check the card with the exit gate station.

DETAILED DESCRIPTION OF THE INVENTION

The invention will be now described by way of specific examples that should not be construed as limiting the scope of possible practical application of the invention.

Events for which the system and method of the invention are applicable may be exemplified by conferences, symposiums, meetings, exhibitions, fairs, trade shows, seminars, cruises, organized travel to resorts, hands-on training courses, school site visits, plant tours, panel discussions, and executive forums. This is does not limit other possible events. For the sake of convenience, however, the system of the invention will be described in relation to such an event as a specialized exhibition, where obtaining of information, data exchange, and security measures are based on the use of a secured identification cards and read/write stations compatible with these cards. In the example, illustrated below admission to the exhibition may be associated with a conference or with invitation cards mailed to the visitors beforehand.

In FIG. 1, the entire event, e.g., an exhibition, is designated by reference numeral 10. First, the structure of the system 10 will be considered in general. The event takes place in closed accommodations, e.g., on a territory surrounded by a fence 12 or in a closed accommodations the admission into which is possible only through an entrance gates, e.g., gates 14 and 16, and exit is possible only through an exit gates 18 and 20. Two entrance gates and two exit gates are shown only as examples. Reference numerals 22a, 22b, . . . 22n designate booths, exhibition stands, etc. (hereinafter referred to as booths) belonging to various exhibitors. The booths are equipped with separate read/write stations. Thus the booth 22a has a station 24a, the booth 22b has a station 24b, etc. Each entrance and exit gate also is equipped with a read/write station. Thus, the entrance gates 14, 16 are provided with rear/write stations 14a, 16a, and the exit gates 18, 20 are provided with read/write stations 18a, 20a.

Depending on specificity of the event, the booths may be separate rooms, halls, or open areas with free excess to all participants admitted to the exhibition through the entrance gates 14 and 16, or access to the exhibits can be restricted and allowed for predetermined visitors.

In the embodiment shown in FIG. 1, all read/write stations 14a, 16a, 18a, 20a, 24a, 24b, . . . 24n are linked into a common network equipped with a central processing unit (CPU) 28.

As usual, a front desk 30 is located outside the closed territory or accommodations 12 and each desk 30a, 30b, . . . 30n is equipped with a data input terminal 32a, 32b, . . . 32n, respectively. When a visitor comes to the front desk, upon presenting an invitation and ID to a front-desk clerk, the latter inputs the visitor's name, visitor's ID or code, as well as other specific data assigned to this particular visitor such as, e.g., admission to all or only to certain booths and he/she receives a secured ID card. In FIG. 1, these cards are designated as 34a, 34b, . . . 34n.

Each event may be accompanied by sub-events such as meals, receptions, literature, concerts, movies, gifts, tournaments, banquet events, gala, food & beverage functions, live entertainment, conference proceedings, conference tote bags, snacks, golf, and commemorative conference pins. This list should not be construed as limiting.

A typical scheme of a sub-event is shown in FIG. 2. The sub-event 38 may also be located on a closed territory 40 with a secured entrance 42 and a secured exit 44 that are equipped with the same read/write stations 42a and 44a, respectively, as the stations 24a, 24b, . . . 24n installed in the booths of the event 10. Let us assume, for example, that the sub-event is a banquette or a dinner with a plurality of menu choices. The participants of the sub-event 38 are admitted to the sub-event by using the same secured ID card that has been given to him/her at the front desk 30. It is understood that the read/write stations 42a and 44a at the entrance and exit, as well as at least one sub-event read/write station 46 (FIG. 2) are compatible with the aforementioned cards. The invitation to a sub-event may be given to a participant at one of the booths 22a, 22b, . . . 22n, and appropriate data are loaded to the sub-event station 46. For example this can be a coded data in the form of a subtractable score associated with cost of the dinner ordered by the participant or with the meals selected at the buffet, where the score is subtracted when the card owner participates in the dinner of the sub-event. In other words, there may be several choices in one sub-event such as attending a buffet or a restaurant, and the use of the secured ID card will allow the card owner to use these choices with registration on the read/write station 42a.

Alternatively, the subtractable score may relate to sub-events themselves, so that the card owner who received the invitations in several booths of the exhibition can visit several sub-events with score subtractable after participation in the sub-event. For example, such sub-events can be obtaining of the literature (sub-event 47), participation in a seminar (sub-event 48), and invitation for a dinner (sub-event 50). All three sub-events may have different locations as shown in FIG. 3. If necessary, entrance and exit from all or some of such sub-events may be provided with a secured entrance/exit stations.

It is understood that a great variety of events and sub-events or their combinations are possible, but in any case, the main principle of the invention consists of providing a system for conducting events, such as the event 10 (FIG. 1) based on the use of a plurality of cards 34a, 34b, . . . 34n (the structure of the card will be described later) in data-exchangeable relation with at least one event station, i.e., a read/write station (described below), at least one secured entrance, such as entrance 14 (FIG. 1) and at least one secured exit, such as exit 18 (FIG. 1). The entrance and exit can be combined into one unit.

Having described the event and sub-event structures in general, let us consider now in more detail the structural components of the system of the invention.

An example of a secured ID card, e.g., any of the cards 34a, 34b, . . . 34n, is shown in FIG. 4. Such cards are known and produced, e.g., by Phillips Semiconductors. The card, let it be for convenience of designation the card 34a, contains an electronic chip 60, which is comprised of an electrically-erasable programmable read-only memory (EEPROM) 52 for storing information relating to a card owner, at least one event, at least one sub-event in the framework of said at least one event, an entrance password, and an exit password;. The card also contains a digital control 54, a chip RF antenna 56 with a chip RF interface 55. The digital control unit 54 may be comprised of a control and an arithmetic logic unit 58, an EEPROM interface, and a coding unit 62. There are also anti-collision unit 64 and an authentification unit 66. Energy and data are transferred via the RF antenna 56 which consists of a coil with a few turns directly connected to the card. The RF-interface includes modulator/demodulator, rectifier, clock generator, and other units (not shown). The anti-collision unit 64 is necessary to prevent conflict with other simultaneously used cards. Preceding any memory operation, the authentification procedure with the unit 66 ensures that access to a block is only possible via the two keys specified for each block. The control and arithmetic logic unit 58 assists in incrementing and decrementing the values stored in a special redundant format. The coding unit 62 secures data exchange. The EEPROM 52 may be the one with 1 Kbyte organized in 16 sectors with 4 blocks each. A block contains 16 bytes. The last block of each sector may contain two secret keys and programmable access conditions for each block in this sector. The card is intended in a contactless interaction with the below-described read/write station. The card may have the following dimensions: Length: 85 mm; width: 54 mm; thickness: 1.25 mm. The card is made of plastic with all electrical components embedded.

A general schematic view of a read/write station, such as any of the aforementioned stations 24a, 24b, . . . 24n, 14a, 16a, 46, etc., is shown in FIG. 5. Let us assume for the sake of designation simplification that this is the read/write station 24a. The station has a casing 70 molded from a durable plastic and contains an RF antenna 72 for contactless interaction and data transmission between the station 24a and the respective secured ID card. Among other things, the casing also contains a power supply battery 74, an internal 1 MB memory unit 76 for data capture application, a real time clock 78, authentification unit 80, the value block 81, the read/write block 83, and an interface for data loading and unloading. Externally, the read/write station contains an LCD display 82, and a data input keypads 84. The station may also have a data communication port 86 for loading the data, e.g., from the Internet.

Before any memory operation can be carried out, the card, such as any of the cards 34a, 34b, . . . , has to be selected and authentificated. By using the value block and the read/write block of the station. With each memory access the internal logic of the station verifies the format of the access conditions. If it detects a format violation, the whole sector is irreversibly blocked.

The station may be installed stationary or may be made in the form a hand-held device with the following dimensions: 172 mm length; 95 mm width; 30 mm thickness.

An example of a transaction sequence between the secure ID card, e.g., the card 34a, and the read/write station, e.g., the station 24a, is shown in FIG. 6.

The method of the invention for conducting high-degree-safety events, such as the specialized exhibition 10, consists of the following. The exhibition facilities, such as the booths 22a, 22b, . . . 22n, the secured entrances 14, 16 and secured exits 18, 20 are equipped with the system hardware, i.e., read/write stations 14a, 16a, 18a, 20a, 24a, 24b, . . . 24n, 32a, 46, etc. A plurality of blank secured ID cards 34a, 34b, . . . 34n are prepared prior to the event. The data such as the card-owner name, entrance and exit password, code of the booth, etc. can be entered into the cards beforehand, or when the attendant shows his/her ID at the front desk, where the front-desk clerk writes in the data into the card in accordance with the information secured for the attendant. All these data are transferred to the appropriate booths via the central processing unit 28.

After the registration and filling in the card, the attendant passes to the territory of the exhibition 10 through one of the secured entrance gates 16a or 16b by interacting in a contactless manner with the appropriate read/write station of the entrance gate. The RF antenna 72 of the station (see FIG. 5) and the antenna 56 of the secured ID card 56 interact when the card approaches the station by the distance not exceeding 50 mm. The processes that occurs during the data interchange have been described above.

In visiting the event booths 22a, 22b, etc., the card owner participates in the event and exchanges the data with the even stations, such as the stations 24a, 24b, . . . . In the same manner as described above. The data are stored in the event stations and can be used later for statistical processing, preparation of future mailing lists, or for security purposes, if necessary to identify the visitors, and to trace their location at any moment of presence at the event, and if necessary, at a sub-event. For exiting the event, the participant has to check the card with the exit gate station 18a or 20a.

If the exhibitors of the specific booth invited a participant to a sub-event, appropriate sub-event data, such as a password, code, etc. is written into the participant's secured ID card at the event station, and the entrance into, participation in, and exit from the sub-event can be performed such as the one described and shown with reference to FIG. 2.

Given is an example of interaction commands between a secured ID card and an event read/write station of the system of the invention.

The above description related to the case of an event controlled by the system for conducting high-degree-safety events wherein all the stations are connected into a network operating in a real time, i.e., all the stations, including the event stations, front desk station, and security entrance and exit stations, are connected to a common central processing unit 28 that registers, stores all the transactions, and can transmit the data to and between all the stations.

However, the system of the invention can be realized in a less centralized form, i.e., without connection of all the event stations into a common network with the central processing unit so that the system can operate in a shared-time mode. An example of such a system is shown in FIG. 7. The system as a whole is designated by reference numeral 90. The event is carried out on a closed territory or in closed accommodations 92 with a secured entrance gate 94 and secured exit gate 96. The entrance gate 94 and exit gate 96 are equipped with read/write stations 94a and 96a, respectively, of the same type as those described above.

A front desk 98 that may contain at least one data input terminal 100 is connected to a self-contained central processing unit 102 that is not connected to any event stations 104a, 104b, . . . 104n of event booths 106a, 106b, . . , . 106n located on the territory 92 of the event. The central processing unit is used only for physical security purposes and not for data exchange between the stations 104a, 104b, . . . 104n and the cards 108a, 108b, . . . 108n shown in FIG. 7 by blocks in front of the front desk 98. The main purpose of the central processing unit is to assign entrance codes or passwords to cards 108a, 108b, . . . 108n of individual card owners for interaction with the event stations 104a, 104b, . . . 104n and gate stations 94a and 96a. Such a system may require for the case of strict internal security without access to the information stored, e.g., in the booth's station, from the central processing unit 102. Responsibility for physical security of the event attendants is entrusted to the read/write stations 94a and 96a of the entrance and exit gates 94 and 96, respectively.

Thus, it has been shown that the invention provides a system and a method for conducting high-degree-safety events that, along with security of access to the event information, are also concentrated on measures in connection with security of admission to and exit from the event, control of the event organization and conducting, and real-time tracing of the participants at any time of the event.

Although the invention has been shown and described with reference to specific embodiments, it is understood that these embodiments should not be construed as limiting the areas of application of the invention and that any changes and modifications are possible, provided these changes and modifications do not depart from the scope of the attached patent claims. For example, a participant may receive more than one card and functions of the card can be separated by security and information data. The card may also contain a magnetic strip and/or bar codes. The card may be made in the form of a badge with a picture and name of the participant. The read/write stations may be portable, or stationary and connected to a personal computer at the boost for operative change and processing of the information.
