Unfettered access to published results

Controlling Access to Published Data Using Cryptography

We propose a framework for enforcing access control policies on published XML documents using cryptography. In this framework the owner publishes a single data instance, which is partially encrypted, and which enforces all access control policies. Our contributions include a declarative language for access policies, and the resolution of these policies into a logical “protection model” which pr...

Examination of all against all comparisons (see below) using this scoring function found that some families consistently scored higher than others. For example some families of membrane proteins would score more highly against other membrane proteins probably due to biases in sequence composition. Therefore, for each pairwise comparison of search outputs the following normali-zation is carried ...
