Description
A DATA PROCESSING SYSTEM
TECHNICAL FIELD
The present invention relates to a data processing system for co-operation between actors, e.g., in a co-ordinated operation for the protection of an area or an establishment, the actors being able to connect to the data processing system via respective communication equipments.
BACKGROUND
In security activities and crisis management of areas having objects that are vital for essential public functions, such as power stations and airports, or in areas where sabotage or terrorist actions could cause great damage, it is important that information can be gathered in a reliable way, that it can be presented to actors involved in the security activities so that it forms proper data for rapid decisions, as well as that the same actors can exchange relevant information while maintaining information security and secrecy.
Upon exchange of information between actors in organizations, such as the police, fire brigade and military, in security activities and crisis management of areas, it may be a need that the information exchange between the individual information domains of said actors is made without running the risk of a third communication equipment connected to the communication system being able of capturing the same data. Occasionally, however, e.g., in a co-ordinated operation for the protection of an area, it may be a need for an actor that is not authorized to get information that is exchanged between two other actors to get a piece of information from the exchanged information and that is important to the action of the non-authorized actor in the operation.
Furthermore, where two or more organizations have the disposal of an information domain each, each one comprising one or more databases, it may be a reluctance to make information in one domain available to another domain. Occasionally, however, it may be a need for an actor in an organization get a piece of information from the information that is available to another organization.
ABSTRACT
An object of the invention is to provide, in a communication system to which actors in a mutual operation can connect, a possibility for an actor, that is not authorized to get information exchanged between at least two other actors, to get a piece of information that is important to the non-authorized actor and can be derived from the exchanged information.
An object of the invention is also to provide a possibility for an actor, which is not authorized to get information available to one or more other actors, to get a important piece of information that can be derived from the information that the actor is not authorized to get.
Said objects are attained by a data processing system for co-operation between actors, the actors being able to connect to the data processing system via respective communication equipments, characterized in that the data processing system comprises a fusion unit that is arranged to
- store information about at least one predetermined type of event, - receive information from at least two of the communication equipments,
- based on the received information, identify an event that corresponds to at least one of the at least one predetermined type of event, and
- send attention information based on the identified event to at least one of the communication equipments.
The communication equipments may be any type of equipments for the usage by the actors and for electronic communication of data, e.g., computers, systems of computers, modems, handheld units such as mobile telephones, etc.
The invention is, among other things, applicable to cases where the data processing system comprises a communication system, and the information that the fusion unit is arranged to receive at least partly is information sent between at least two of the communication equipments, or at least a part of information sent between two of the communication equipments, via the communication system. In such cases, the communication system may be arranged to prevent receipt by at least one of the communication equipments of information sent between two other ones of the communication equipments, as is discussed in more detail below.
The fusion unit has data processing and data storage capacity and stores information about at least one predetermined type of event. The predetermined type of event may be such a one in which at least one of the actors is involved. Furthermore, type of events may be defined as predetermined conditions in a software in the fusion unit. An example of a type of event is that a position of a target for the fighting means or weapon of an actor (e.g., a police squad) coincides with a position or a direction of another actor, (e.g., a fireman). Another example of a type of event is that a position or a direction of movement of an actor coincides with the position or direction of movement of a certain object, which object (e.g., a wanted person or vehicle, or dangerous part of a guarded establishment) is included in the type of event since it may constitute a danger to an actor in the operation.
The fusion unit is arranged to identify, or derive, based on the received information, an event that corresponds to at least one of the at least one predetermined type of event. The identified event may be such a one that at least one of the actors is involved in it. The identification may be effected by comparison of the received information with the predetermined type of event, and determination of whether there is correspondence between the type of event and contents in the received
information. When the type of event is formulated as a condition in a software, the determination may comprise establishment of whether contents in the received information meet the condition.
The actor(s) that the fusion unit can send attention information to via the respective communication units may be at least one of the at least one actor involved in the identified event. This attention information only needs to contain information required for the actor in his or her present situation. Only such attention information, i.e., no additional information, needs to be sent from the fusion unit. On the other hand, if no identification of an event that corresponds to a stored type of event occurs, then the fusion unit does not need to send any information at all. Thus, only attention information based on an identified event, and no other of the information received by the fusion unit, can escape.
The formation of the attention information as well as the receiver(s) of it can be adapted according to the needs of the actors. These needs can be determined based on the position and role of the respective actor in a mutual operation. Said needs can also be determined based on events in the vicinity of the actor or what may be feared to happen in the vicinity. Feared courses of events can be determined based on occurred or probable chains of events as well as registered properties of persons or objects in the vicinity of the actor.
The invention can also be used to eliminate the need for actors to carry communication equipments having its own powerful data processing capacity locally. In addition, actors can get the attention information presented to himself or herself in the form of a distinct warning having direction and character. Such warning may, e.g., occur acoustically by a communication equipment in the form of an earphone of a protection guard or policeman.
The invention is also applicable to cases wherein communication equipments in separate information domains can send information to the data processing system
without communication taking place between the communication equipments. More generally, the invention may be applicable to cases wherein a first one and a second one of the communication equipments, from which the fusion unit is arranged to receive information, are arranged to communicate with a first and a second database, respectively, the first communication equipment being unable to communicate with the second database, and vice versa.
In that connection, the predetermined type of event and the identified event do not necessarily need to be such that at least one of the actors is involved in them. A further example of a type of event is that a stolen car appears at a guarded establishment. In that connection, one of the communication equipments may belong to the police and information received by the fusion unit from this communication equipment may be information that identifies stolen cars according to a register in a database disposed by the police. Furthermore, another one of the communication equipments may belong to an organization for the surveillance of the establishment, and information received there from by the fusion unit may be information based on images from surveillance cameras and number recognition of car number plates that appear in the images. Based on the received information, the fusion unit can identify, or derive, an event that corresponds to the predetermined type of event, i.e., that a stolen car appears at the establishment. Then, the attention information may comprise the event and be sent by the fusion unit to a communication equipment that belongs to an actor of the police. As in the examples above, only attention information based on an identified event, and no other of the information received by the fusion unit, can escape.
Preferably, the information about the at least one predetermined type of event stored in the fusion unit contains predetermined expressions that are identical with expressions used in the information received from the at least two communication equipments. This means that the information received by the fusion unit and the information of type of event stored in the fusion unit contain common predetermined expressions. The predetermined expressions may be words or
designations used in messages between the communication equipments, e.g., "target", "threat", "movement" or "position". This facilitates the identification of the event as mentioned above, based on the received information that corresponds to at least the predetermined type of event.
Preferably, the fusion unit is arranged to store the received information, besides which the fusion unit has at least one connection to at least one other component in the data processing system, wherein the fusion unit may be a separate physical unit, and the fusion unit is arranged to detect a disconnection of at least one of the at least one connection and, in response to the detection of the disconnection, delete the stored received information, or at least a part thereof. In addition or alternatively, where the fusion unit comprises an openable cover, the fusion unit may be arranged to store the received information, and to detect an opening of the cover and, in response to the detection of the opening, delete the stored received information, or at least a part thereof. Thereby, unauthorised access to the information is prevented.
Preferably, data processing systems comprise a communication system that comprises at least three communication members for wireless, electromagnetically isolated communication, each one of the communication members being arranged to communicate with one respective of at least three of the communication equipments, besides which the communication system comprises a communication control unit that is arranged to prevent receipt by at least one of the communication members of information sent between two other ones of the communication members.
The communication members may be arranged to communicate by electromagnetic waves of any suitable type, e.g., radio waves, micro waves (e.g., blue-tooth), infrared light, visible light or ultraviolet light. The embodiment involves that data can be exchanged between two information domains, without running the risk of a third communication equipment connected to the communication system being able of capturing the same data. By all communication being wireless, the units will be
able to communicate with each other without being electronically interconnected. Furthermore, since the communication between the communication members is electromagnetically isolated, receipt of said communication by other means than the communication members is prevented. Thus, the communication between the communication members cannot be recorded by means outside the electromagnetic isolation. The communication system is arranged so that what is sent by one communication member can be captured only by one of a plurality of other communication members that can do this in accordance with the control. Thus, certain communication members can be prevented from listening to certain information, while the fusion unit provided according to the invention can guarantee that required information still reaches any actor that has a need of it.
Preferably, the communication members are arranged in at least one electromagnetically isolated room, for the provision of the electromagnetic isolation. In that connection, the communication members are arranged to communicate in the room, and preferably all communication in the room is wireless.
In certain embodiments, the communication control unit is arranged to prevent said receipt by controlling a periodically repetitive time window for receipt by the at least one communication member. Thus, in that connection, the communication control is unit arranged to control a time division, distributed between the communication units, of sending and/or receiving of information by the communication units.
The communication control unit may be arranged to prevent said receipt by means of electromagnetic shielding of the at least one communication member from the two other ones of the communication members. Such a shielding can be effected using a barrier that is adapted to the frequency used for the communication, e.g., coloured glass in IR communication. The barrier may be arranged to be moved
mechanically in the room for the provision of the desired shielding, as well as for removal when shielding is not desired.
As an alternative to said time division, the communication control unit may be arranged to prevent said receipt by means of frequency division for sending and/or receiving by the communication members.
Preferably, at least one of the communication members is arranged to communicate with the communication equipment via an encryption means for encrypting data being sent to the communication equipment and decrypting data being sent to the communication member. This means that an internal crypto for encryption in an information domain, which comprises the communication equipment, does not need to be exchanged with any of the other communication equipments that are connected to the electromagnetically isolated room, since traffic through the electromagnetically isolated room offers a security that replaces the security provided by the internal encryption. Thus, an actor in security activities and crisis management can let the respective information domain thereof communicate with the domain of another actor, without the domains needing to exchange cryptos with each other, and without running the risk that also other traffic than the traffic intended for the information exchange between the actors could be overheard by the other actor.
DESCRIPTION OF THE FIGURE
Embodiments of the invention will be described in more detail below, reference being made to the drawing, in which Fig. 1 schematically shows a communication network having a data processing system.
DETAILED DESCRIPTION
Fig. 1 schematically shows a communication network having a data processing system 11 according to an embodiment of the invention. The data processing system 11 is arranged to communicate externally with communication equipments 511 , 521 , 531 , in the form of computers or handheld units, in a first, a second, and a third, respectively, information domain 51, 52, 53. In the first, second and third information domain 51, 52, 53, there are also a first, a second, and a third, respectively, database D51, D52, D53 that are accessible by means of domain- internal cryptos of the communication equipments 511 , 521 , 531 in the respective information domain 51, 52, 53.
The data processing system 11 comprises also a communication system 1 for communication between communication equipments 511, 521, 531, in different information domains 51, 52, 53. The communication system 1 comprises a first, a second and a third communication unit 21, 22, 23, each one of which can communicate externally with the communication equipments 511, 521, 531.
The communication system 1 comprises also an electromagnetically isolated room 4, in which there is a first, a second, and a third, respectively, communication member 41, 42, 43 in the form of a respective antenna for the sending and receipt of wireless information. This information is communicated via electromagnetic waves of any suitable type, e.g., micro waves (blue-tooth) or IR. The first, second and third communication member 41, 42, 43 is, via a respective cable, connected with the first, second, and third, respectively, communication unit 21, 22, 23.
Each communication unit 21 , 22, 23 is situated outside the room 4, as well as physically separated from other communication units 21, 22, 23. All communication between the communication units 21, 22, 23 takes place wirelessly via the communication members 41, 42, 43 in the room 4. The communication system also comprises a communication control unit 6 that is arranged to control, by
controlling the communication units 21, 22, 23, the communication in the room 4 using a time division so that communication between two of the communication units 21, 22, 23 cannot be caught by the third communication unit 21, 22, 23. More precisely, communication between two of the communication units 21, 22, 23 can only occur in a periodically repetitive time window. The number of time windows is the same as the number of communication members 41, 42, 43, and these time windows follow cyclically one after the other. The electromagnetic isolation of the room 4 excludes information exchange with other communication units 21, 22, 23 than the communication units 21, 22, 23 communicating for the moment.
As alternative for the control of the communication units 21, 22, 23, the communication control unit 6 may be arranged to provide said control of the communication in the room 4 by means of electromagnetic shielding in the room of one of the communication members 41, 42, 43 from the two other ones of the communication members 41, 42, 43. Such a shielding can be effected using a barrier that is adapted to the frequency used for the communication, e.g., coloured glass in IR communication. The barrier may be arranged to be moved mechanically in the room for the provision of the desired shielding, as well as for removal when shielding is not desired.
As an alternative to said time division, the communication control unit 6 may be arranged to control the communication in the room 4 by means of frequency division for sending and/or receiving by the communication members 41, 42, 43. The number of frequencies may be the same as the number of communication members 41, 42, 43, and reserved for the communication between the respective pair of communication members 41, 42, 43.
As an additional alternative, the communication system 1 may comprise optocouplers, (optical isolators), wherein the communication members 41, 42, 43 may be light emitting diodes and photocells in the optocouplers. In such an embodiment, the communication control unit 6 is preferably arranged to control one
or more multiplex units for the control of signals between the communication units
21, 22, 23 and the optocouplers.
The communication units 21, 22, 23 comprise respective encryption means 31, 32, 33, which, e.g., may be provided in software form and executed by respective computer processors and RAM memories in the respective communication unit 21 ,
22, 23. In that connection, data being sent from a domain 51, 52, 53 to the respective communication member 41, 42, 43, and that is encrypted using a domain-internal crypto, can be decrypted by the respective encryption means 31, 32, 33. Conversely, data being sent from a communication member 41, 42, 43 to a respective domain 51, 52, 53, and which is not encrypted using the domain-internal crypto, can be encrypted by the respective encryption means 31, 32, 33. This means that an internal crypto for encryption in an information domain 51 , 52, 53 does not need to be exchanged with any of the other information domains 51, 52, 53.
It should be mentioned that more than three domains may be connected, via the respective communication member 41, 42, 43, to the room 4 in Fig. 4. Furthermore, information may be sent from a domain to a plurality of other domains, while other domains cannot catch this communication.
The control of the information exchange in the room 4 may be effected based on a plurality of conditions, such as a given priority of traffic to a certain domain or communication equipment.
The communication system 1 comprises a fusion unit 8 that is arranged to store information about a number of predetermined type of events, examples of which have been mentioned above, as well as to receive information from at least two of the communication equipments 511, 521, 531, which belongs to separate information domains 51, 52, 53. Particularly, the fusion unit is 8 arranged to receive information sent between communication equipments 511 , 521 , 531 that belongs to separate information domains 51, 52, 53.
The fusion unit 8 is furthermore arranged to identify, in the way exemplified above, based on the received information, an event that corresponds to at least one of the predetermined type of events. The fusion unit 8 is furthermore arranged to provide attention information based on the identified event and send this attention information to at least one of the communication equipments 511, 521, 531.
