  1. Research Institute For Symbolic Computation (RISC), Johannes Kepler University, Linz, Austria http://www.risc.uni-linz.ac.at An Extended Design of the “Grid Enabled SEE++ System” Based on Globus Toolkit 4 and gLite Authors: K. Bosa, W. Schreiner, T. Kaltofen, M. Buchberger http://www.uar.at http://www.strabismus.at

  2. Introduction The “Grid Enabled SEE++” deals with the support of diagnosis and treatment of strabismus. The Content of the Presentation: Goals Previous Results An Architecture based on Globus 4 Security for the SEE++ Database A Design of a gLite Compatible SEE++

  3. Goals of the “Grid Enabled SEE++” The goal of project is to develop an efficient grid-based tool for ``Evidence Based Medicine'', which supports the surgeons in the following ways: • it speeds up the Hess-Lancaster test simulation (parallel grid-enabled Hess-Lancaster test); • it determines/estimates the pathology of the patients in reasonable time (grid based pathology fitting); • It collects, stores, shorts and evaluates patient data and known pathological cases for improving the future medical treatments (grid enabled medical database).

  4. Former Results We speeded up the Hess-Lancastertest by a factor of 14-17 Initial Grid Enabled Architecture We designed a grid-enabled Pathology Fitting algorithm We developed a Web Service based medical database for SEE++ Karoly Bosa, Wolfgang Schreiner, Michael Buchberger, Thomas Kaltofen, SEE-GRID, A Grid-Based Medical Decision Support System for Eye Muscle Surgery, 1st Austrian Grid Symposium, December 1-2, 2005, Hagenberg, Austria.

  5. An Architecture based on Globus 4 The Dashed Line Denotes the Existing Components

  6. Security for the SEE++ Databases I.) Security between the SEE++ clients and the bridge (outside of the grid) : • Encrypting any network transfer via HTTPS or SSL by Stunnel. II.) Security between bridge and the WSRF Databases (inside of the grid) : a.) Solutions developed for system b.) Solutions provided by the Grid • For each Web Service call, the caller's identity is checked separately (User ID + Password). • Stored user passwords is encrypted with an SHA-512 salted hash and stored in an independent database. • Encrypting any network transfer (planned). • Checking the authorization of the bridge by certificates (planned). • Managing VOs (planned)

  7. A Design of a gLite Compatible SEE++
