Method and System for Cross -

Many services need to gather relevant information when performing certain functions . For example, a delivery scheduling service needs to obtain the consumer address and phone numbers, the product ordered, and the availability of trucks/drivers to make an appointment. Such information might be hosted by other services, located in possibly different administrative domains. The gathering of relevant information has been done manually or ad hoc by setting up connections between services on demand when needed. Such an approach does not scale, and becomes a management nightmare

when each domain has particular rules and regulations about what information can be shared with which other domain/services. If not done carefully, sensitive information can be leaked to unintended recipients, causing risks and losses for companies.

The novel contribution is a method and system for automatic gathering of such relevant information possibly residing in different administrative domains . This systematic approach ensures the secure and policy-conforming sharing of information across domain boundaries.

The method and system comprise three pieces to automate the gathering of relevant information. The first is ontology to represent the kinds of relevant information for a service to discover what information it needs. The second is a collection of gateways, each residing in a different domain, which form an interconnected overlay network and serve as a distributed directory service to find which other services in which other domains possess the relevant information. The third is a set of protocols and mechanisms to ensure the information is shared with only intended recipients and in required forms and granularity.

With this approach, each organization has one or multiple Virtual Information Exchange (VIE) gateways. The gateways connect to each other to form an overlay network . The gateway provides the following functions:

• A metadata service that uses ontology to describe the kinds of data a service provides

• A directory service hosted collectively by gateways to find which services in

which domains possess relevant information

• A routing service that propagates queries or return data for the requester

• A policy examination service that determines who is authorized to access what kinds of information

The VIE automatically identifies and securely transports data across domain boundaries while conforming to policies. A caller service requesting data sends a query to the local directory service. The directory service examines local the metadata service to find relevant local information. The directory service also propagates the query to other connected gateways to find out which services in which organizations have relevant data.

Based on the caller identity, the system discov...
