Abstract
Methods and apparatus, including computer program products, implementing and using techniques for protecting data residing in a repository of an electronic product code information service against undesired data disclosure. One or more disclosure policies are defined for an item tagged with an electronic product code. The item has associated data stored in the repository. The disclosure policies describe one or more of: who is permitted to query the repository for information, what type of information is permitted to be obtained from the repository in response to a query, and under what condition the repository can be queried. The disclosure policies are enforced in response to a received query from a party by only disclosing a subset of the data from the repository, the subset being determined in accordance with the defined one or more disclosure policies. A web-based tool for defining disclosure policies is also described.
