Embodiments relate to sensors, clients, servers, and databases. Embodiments also relate to identification data, image processing, and card readers.
There are many systems and methods currently used for obtaining identification data and for detecting the presence of people and vehicles. Driver's license readers are used to control access to buildings. Road loops are used to detect the presence of vehicles. Traffic cameras are used record pictures of speeding vehicles or video of vehicles illegally traversing intersections.
Driver's license readers can be stand alone units or connected units. Stand alone units are sometimes used to control access to venues such as liquor serving establishments. A door man can pass a prospective patron's driver's license through a driver's license reader. The reader can indicate the person's age and can also store data contained in the driver's license. The stored data can later be uploaded to a computer and used to produce mailing lists or demographic statistics. Connected driver's license readers can be connected to a computer by a serial cable, USB cable, a telephone modem, or an Ethernet connection. The computer can then automatically upload the driver's license data.
Road loops have been used as sensors for traffic light sensors, traffic sensors, and camera sensors. A vehicle in the road loop can cause a signal wire to transition to an “on” state. Cameras, counters, and traffic lights can interrogate the signal wire and react to the state of the signal wire.
Traffic cameras are often used to video traffic. In many cases, the traffic cameras are also used to gather evidence for use against speeders and red light runners. A person examines the evidence to determine the transgressing vehicles license plate number. A database query to a vehicle registration database can identify the vehicles owner who then receives a traffic fine.
There are many isolated system for gathering personal data as people move about. Systems and methods for using the personal data as tracking data are needed.
The following summary is provided to facilitate an understanding of some of the innovative features unique to the embodiments and is not intended to be a full description. A full appreciation of the various aspects of the embodiments can be gained by taking the entire specification, claims, drawings, and abstract as a whole.
It is therefore an aspect of the embodiments that a database server and a graphical user interface (GUI) are subscribing clients to one or more identification servers. A subscribing client is a client that subscribes to a server. A client can subscribe to a server by sending a message to the server requesting that the server send certain messages to the client.
It is also an aspect of the embodiments that messages are transmitted over a communications network. The messages are made of data packets. For example, communications over the internet predominantly use the transmission control protocol (TCP) which in turn uses the internet protocol (IP). IP specifies the formation and transmission of data packets whereas TCP specifies reliably sending and receiving messages composed of IP data packets.
It is a further aspect of the embodiments that the identification servers have input modules and server modules. An identification event can trigger the input module to obtain identification data. Obtaining the identification data can trigger the server module to send id messages to its subscribing clients. The id messages can contain the identification data. Alternatively, the identification data can be stored in a database module in association with a key and the id message can contain the key. The key can later be used to retrieve the identification data from the database module.
The accompanying figures, in which like reference numerals refer to identical or functionally similar elements throughout the separate views and which are incorporated in and form a part of the specification, further illustrate aspects of the embodiments and, together with the background, brief summary, and detailed description serve to explain the principles of the embodiments.
The particular values and configurations discussed in these non-limiting examples can be varied and are cited merely to illustrate at least one embodiment and are not intended to limit the scope thereof. In general, the figures are not to scale.
Identification servers are small, perhaps embedded, systems that can be used as subsystems of a tracking and verification system. An identification server can obtain identification data when a trigger, called an identification event, occurs. The identification server can store the identification data in a database module with a key. The identification server can send a message containing the identification data or the key to a set of subscribing clients. Subscribing clients, such as a central database or a graphical user interface, are clients that subscribe to receive messages from the identification server. An identification server can trigger off of an identification message sent by another identification server.
Simple server 108 is similar to identification server 105. Identification event 2104 triggers the input module 109 of simple server 108 to obtain identification data 2103. Server module 110 can then encapsulate identification data 2103 into id message 2111 and send it to the subscribing clients. One of the subscribing clients is processing server 113.
Processing server 113 treats Id message 111 as an identification event that triggers input module 114 to obtain raw data 112. Raw data 112 is passed to processing module 115 that processes raw data 112 to produce identification data that is then passed to server module 116. The server module 116 then sends the identification information within Id message 119 to the subscribing clients.
The license plate camera 210 obtains a license plate image 219 of the vehicle's 218 license plate 206 when the license plate server 209 receives id message 208. The license plate image 219 is passed to an image processor 211 that reads a plate number 221. The plate number 221 is stored in a database module 212 with a key 220. The Id message then sent by the server module 213 is a plate obtained message 214 containing the key 220. A subscribing client 217 receives the plate obtained message 214. After determining that it needs the plate number 221, the subscribing client 217 send a request message 215 containing the key 220 to the license plate server 209. The key 220 is used to retrieve the plate number 221 from the database module 212. The plate number 221 is then sent in a response message 216 to the subscribing client 217.
Some events can be programmed events. For example, a GUI can send a subscription request to a driver's license reader with the desired event being “FirstName=Tyler, LastName=Durden”. Similarly, it subscribes to a license plate server with a programmed event looking for Tyler Durden's license plate number. The person watching the GUI in this case is quite obviously tracking Tyler Durden. The central database server of

Also that various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
