DETAILED DESCRIPTION

FIG. 1 illustrates an exemplary embodiment of a system for sharing data between connected devices over a network according to the present invention. The system includes one or more data producing devices 102-103 connected to one or more data consuming devices 104-105 over a network 101. In this exemplary embodiment, the network 101 is the Internet, and the device 102-105 are connected via an Internet of things (IoT) system. Each device 102-105 is uniquely identifiable in the network 101 and is able to interoperate within the Internet infrastructure. The data producing devices 102-103 may be augmented with sensors, actuators, and other components that collect data about a user of the device, usage activities, device location or environment, etc. The data consuming devices 104-105 may be augmented with components that may use the data collected by the data producing device 102-103 to perform some type of useful work. The devices 102-105 connected to a network device 106 over the network 101, such as a server providing a data market service, where the network device 106 includes a publish-subscribe (pub-sub) module 107, a cognitive computing module 108, and a storage 109. The pub-sub module 107 manages the sending of messages from publishers, e.g., the data producing devices 102-103, to subscribers, e.g., the data consuming devices 104-105. In this exemplary embodiment, the cognitive computing module 108 determines terms upon which the data producing devices 102-103 may provide data access to the data consuming devices 104-105 using a computerized cognitive model. The cognitive computing module 108 comprises a self-learning system that uses data mining, pattern recognition, and natural language processing to simulate human thought processes. The cognitive computing module 108 determines the terms without requiring human assistance or intervention. The cognitive computing module 108 further comprise a machine learning module (not shown) to continually process data input by the devices 102-105 and identify patterns in order to anticipate new problems and model possible solutions. The devices 102-106 of the system implement the sharing of data over the network 101 as described further below.

FIG. 2 illustrates an exemplary embodiment of a method for sharing data between connected devices over a network according to the present invention. In the method, the network devices 106 broadcasts the availability of a set of data collected by a data producing device 102 (or 103) coupled to the network 101 (201). The network device 106 receives a request to access the set of data from a data consuming device 104 (or 105) coupled to the network 101 (202). The cognitive computing module 108 of the network device 106 determines a set of terms between the data producing device 102 and the data consuming device 104 for access to the set of data (203). In response to the determination of the set of terms, the network device 106 obtains the set of data and a first key from the data producing device 102 (204), which the network device 106 may store in the storage 109. The data producing device 102 also sends a second key associated with the first key to the data consuming device 104. Upon receiving the second key from the data consuming device 104, the network device 106 determines that the second key is associated with the first key (205). In response to determining that the second key is associated with the first key, the network device 106 provides access to the set of data to the data consuming device 104 according to the set of terms (206).

FIG. 3 illustrates in more detail the exemplary embodiment of the method for sharing data between connected devices over a network according to the present invention. The pub-sub module 107 of the network device 106 receives a message from the data producing device 102 coupled to the network 101 of the availability of a set of data collected by the data producing device 102 (301). The message may include the set of data. The set of data may include the type of device of the data producing device 102, the category of the data, demographics or other profile information for a user of the data producing device, data on the usage activity, an environment of the data producing device, a location of the data producing device during an activity, and other data that may be collected by the data producing device 102. A user of the data producing device 102 may configure the device 102 such that limitations are placed on the sharing of the set of data. For example, the device 102 may be configured to share certain collected data while maintaining privacy on other collected data. The data may be configured to be shared anonymously, without any identifying information or with limited identifying information. Upon receipt of the message, the pub-sub module 107 identifies a subscription matching the set of data (302). The subscription may match based on the type of data, demographic information, device type, etc. Upon identifying a matching subscription, the pub-sub module 107 sends a notification of the availability of the set of data to the data consuming device 104 associated with the subscription (303). When the data consuming device 104 receives the notification, the data consuming device 104 may decide whether or not to request access to the set of data. If the data consuming device 104 decides to request the access, then the data consuming device sends a request for access to the network device 106. When the network device 106 receives the request to access the set of data from the data consuming device 104 (304), the cognitive computing module 108 of the network device 106 determines a set of terms for access to the set of data, according to a cognitive model, between the data producing device 102 and the data consuming device 104 (305). The cognitive computing module 108 determines the terms based on inputted data and observations specifically pertaining the data producing device 102 and the data consuming device 104 and/or based on devices of the same or similar type as the devices 102 and 104. The set of terms may include any combination of: a level of access (e.g. a higher price for earlier access); a time when the set of data is accessible; a length of time during which the set of data is accessible; an amount of the set of data that is accessible; a location at which the set of data is accessible; limitations on the usage of the set of data; and a payment, barter, or other compensation for access to the set of data. Other terms or combination of terms may be possible.

Once the set of terms are determined, the network device 106 sends a notification to the data producing device 102 and the data consuming device 104 of the set of terms (306). Optionally, one or both of the data producing device 102 and the data consuming device 104 may confirm agreement to the set of terms before proceeding. In response to this notification, the data producing device 102 sends the set of data and a first key to the network device 106 and sends a second key associated with the first key to the data consuming device 104. In an exemplary embodiment, the first key includes an encrypted key that lists what of the set of data the data consuming device 140 can access. The network devices receives the set of data and the first key from the data producing device 102 and stores them in the storage 109. The set of data, the first key, and the set of terms would be associated with each other at the network device 106. To obtain access, the data consuming device 104 sends to the network device 106 a request to access the set of data and the second key. Upon receiving the request for access and the second key from the data consuming device (308), the network device 106 determines whether the second key is associated with the first key (309). If the second key is not associated with the first key, then the network device 106 denies access to the data consuming device 104 (311). If the second key is associated with the first key, then the network device 106 provides access to the set of data to the data consuming device 104 according to the set of terms (310).

For example, assume that a customer enters a bicycle shop with multiple data producing devices 102-103, such as a bicycle computer, a fitness watch, a cell phone, a health application on the cell phone, and demographic data on the customer. The data producing devices 102-103 have various collected data according to their configured functions. The customer has configured the data producing devices 102-103 so that the data collected by the data producing devices 102-103 may be available to other data sharing devices in the network 101 via the pub-sub module 107 under certain conditions, optionally for sale or barter. Assume also that the bicycle shop has a data consuming device 104 with a subscription with the pub-sub module 107, where the subscription is configured with conditions defining the data of interest. Referring to FIG. 3, upon detecting the close proximity of the data producing devices 102-103 of the customer and the data consuming device 104 of the bicycle shop, the data producing devices 102-103 sends a message to the pub-sub module 107 of the availability of data collected by the devices 102-103 (301). The pub-sub module 107 identifies the subscription of the bicycle shop's data consuming device 104 and the set of data available from the customer's data producing devices 102-103 as having matching conditions (302). The pub-sub module 107 sends a notification of the availability of the set of data to the data consuming device 104 of the bicycle shop (303). Assume that the data consuming device 104 sends a request for access to the network device 106 in response to the notification. When the network device 106 receives the request (304), the cognitive computing module 108 determines a set of terms between the data producing devices 102-103 of the customer and the data consuming device 104 of the bicycle shop (305). The network device 106 then sends a notification of the set of terms to the data producing devices 102-103 of the customer and the data consuming device 104 of the bicycle shop (306). The data producing devices 102-103 each sends their respective data and a first key associated with the data to the network device 106 and sends a second key associated with the first key to the data consuming device 104 of the bicycle shop. Assume that the data consuming device 104 of the bicycle shop then sends a request for access to the set of data from the data producing device 102 with the second key. Upon receiving the request and the second key from the data consuming device 104 of the bicycle shop (308), the network device 106 determines whether the second key is associated with the first key from the data producing device 102 (309). Assume that the second key is determined to be associated with the first key, in response to which the network 106 provides access to the data from the data producing device 102 according to the set of terms (310). Assume in this example that the set of terms includes a payment to the data producing device 102. The network device 106 may facilitate the payment and allow access to the set of data only after the payment transaction is complete. In this manner, data may be automatically exchanged between data producing devices and data consuming devices within an IoT system without user interaction or intervention.

The data producing device 102-103, the data consuming device 104-105, and the network device 106 may each be implemented as a computing system.
