Optical memory card applicability for implementing a portable medical record

The implementation of portable record based on laser card technology is discussed in terms of data structures for quick access and software tools to reinforce security and confidentiality as required by medical data. Experimental results from a field test with a laser card technology are reviewed with regard to implementation in a large-scale and public information system. An efficient data structure is described for storage purposes, and some proposals are put forward to secure stored data.
