Method and system for sharing access to a database

A computer system for sharing, among a plurality of users utilizing computing devices connected to a network, access to a plurality of records, each user is an owner of one or more of the plurality of records, each record describes one of a plurality individuals and identifies the owner of the record, the system comprising:

• one or more processors configured to:
• disseminate one or more sharing rules, each rule is provided by the owner of a respective one or more records and identifies at least one of the plurality of users to whom access to the one or more records is permitted;
• calculate a unique identifier corresponding to one of the plurality of individuals based on at least one of the individual's name, location and occupation;
• in response to a query from a first user of the
• plurality of users identify
• a first subset of records owned by the first user, which permits the first user to access the first subset of records, and
• a second subset of records not owned by the first user, wherein the at least one sharing rule permits the first user to access the second subset of records, wherein the records in the first subset of records and the second subset of records describe the individual corresponding to the unique identifier;
• and
• provide, for each of the plurality of users, one or more volume rules specifying a number of the plurality of records the user is allowed to access responsive to one of the query and a predetermined period of time.

A computer program product comprising a non-transitory tangible storage medium encoded with processor-readable instructions that, when executed by one or more processors within a computer system, cause the computer system to perform a method of sharing, among a plurality of users utilizing computing devices connected to a network, access to a plurality of records, each user is an owner of one or more of the plurality of records of individuals and identifies the owner of the record, the method comprising:

• disseminating one or more sharing rules, each rule is provided by the owner of a respective one or more records and identifies the plurality of users to whom access to the one or more records is permitted;
• and
• calculating a unique identifier corresponding to one of the plurality of individuals based on at least one of the individual's name, location and occupation data;
• in response to a query from a first user of the
• plurality of users identifying
• a first subset of records owned by the first user, which permits the first user to access the first subset of records, and
• a second subset of records not owned by the first user, wherein the at least one sharing rule permits the first user to access the second subset of records, wherein the records in the first subset of records and the second subset of records describe the individual corresponding to the unique identifier;
• and
• providing, for each of the plurality of users, one or more volume rules specifying a number of the plurality of records the user is allowed to access responsive to one of the query and a predetermined period of time.
