Automatic Record Hash Coding and Linkage for Epidemiological Follow-up Data Confidentiality

1 Jul 1998

Abstract excerpt

A protocol is proposed to allow linkage of anonymous medical information within the framework of epidemiological follow-up studies. The protocol is composed of two steps; the first concerns the irreversible transformation of identification data, using a one-way hash function which is used after spelling processing. To avoid dictionary attacks, two large random files of keys, called pads, are introduced. The...
