The AEGIS platform promises a novel approach in data sharing and exchanging: a safe environment for the stakeholders to sell and purchase datasets, data services, algorithms or intelligence reports; what is generally known as “Data Assets” in AEGIS terminology.
This environment is based on a Data Policy Framework and it is managed by a Business Brokerage mediator. Both aim to provide useful tools that cooperate with each other to guarantee a secure and trusted exchange environment.
Each transaction in AEGIS platform involves a Data Asset Provider, a Data Asset Consumer and, of course, a Data Asset. Such a transaction is governed by a Data Policy Framework, which may consist of various sets of permissions and requirements, involving usage rights, pricing schemes, quality standards, or privacy/license terms and conditions.
The following picture shows an example of the Policy Framework to be adopted by AEGIS. There are four distinctive groups of policies: the Data Asset Rights group, the Data Asset Quality group, the Pricing Model and the Policy Terms. The orange shapes above each element denote the Data Asset they can be applied to.
The Business Brokerage Framework (BBF), on the other hand, has been designed so as to formally define and dictate transaction terms, supervise their execution, and make sure everything runs seamlessly and reliably.
The BBF implementation is supported by a blockchain architecture that will allow platform users to perform transactions under the same set of rules, with integrity and transparency. A typical transaction workflow (pic.3) begins with a Data Asset request by the customer (Data Asset Consumer). The BBF listener responds to the request and broadcasts the transaction to the BBF nodes, which in turn verify (or not) the transaction. If everything is ok, the transaction is added to the chain and distributed back to the network. The final step concludes the process by delivering the produced contract safely to the seller (Data Asset Provider).
