Ontario introduces “hospital secrecy clause”

Secrecy logic: S -secrecy structures

Let S = 〈L, S〉 be a deductive system. An S -secrecy logic is a quadruple K = 〈FmL(V ),K,B, S〉 , where FmL(V ) is the algebra of L-formulas, K,B are S -theories, with B ⊆ K and S ⊆ K such that S ∩ B = ∅ . K corresponds to information deducible from a knowledge base, B to information deducible from the publicly accessible (or browsable) part of the knowledge base and S is a secret set, a set of s...

Chronic inflammatory demyelinating polyradiculoneuropathy: in a remote northern Ontario hospital.

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired demyelinating syndrome that targets myelin sheaths of the peripheral nervous system. The course might be relapsing or steady, or follow a stepwise progression, with most younger individuals presenting with the relapsing course and older individuals presenting with the progressive course.1 It is more common in men, a...

Secrecy-Preserving Reasoning using Secrecy Envelopes

Inmany applications of networked information systems, the need to share information often has to be balanced against the need to protect secret information from unintended disclosure, e.g., due to copyright, privacy, security, or commercial considerations. We study the problem of secrecy-preserving reasoning, that is, answering queries using secret information, whenever it is possible to do so,...
