Patent ID: 7890394

Claim:
A method for securing information within a computing system, the method comprising: identifying, using an applications server computer, a first entity associated with data representing at least a portion of transactional information; retrieving, with the applications server computer, a first context associated with the first entity from a context table database, the first context having a first valid time period, the first context identifying a first subset of the at least a portion of transactional information that was generated during the first valid time period; identifying, with the applications server computer, a second entity having a relationship to the first entity; retrieving, with the applications server computer, a second context associated with the second entity from the context table database, the second context having a second valid time period, the second valid time period identifying a period of time the relationship is effective; determining, with the applications server computer, a second subset of the first subset, the second subset identifying the at least a portion of transactional information that was generated during the second valid time period; authorizing, with the applications server computer, access by the second entity to the second subset of data at any point in time, independent of the first valid time period or second valid time period; authorizing, with the applications server computer, access by the second entity to the first subset of data during the second valid time period; and denying, with the applications server computer, access to portions of the first subset of data that are not included in the second subset of data during periods outside of the second valid time period.
