A description is provided of a conceptual model for a data secure system. The discussion first offers a formal working vocabulary and next, using the intuitive idea of a dichotomy between permissible and impermissible accesses, formalizes the idea with an Extended Logical Data Base and with protection specifications and patterns. These…

Although the indispensibility of access control mechanisms in data secure systems has been recognized, there is a need for more subtle protection and refined control mechanisms.

A data integrity program is to be built around a Data Base Manager (DBM), an individual or a group of…

This report examines a series of general models that represent the process of merging records from separate files when it becomes essential to inhibit identifiability of records in at least one of the files. Models are illustrated symbolically by flow diagrams, and examples of each variation are taken from the social sciences. These variations…

The 13 papers collected here were presented at the Workshop on Data Documentation held at Reisenburg Castle, Federal Republic of Germany, in July 1975. This workshop was a first attempt to identify some of the problems in the field of data documentation, formulate them, and solve them as far as possible. The subject was approached from four…

Current regulations and guidelines established by the Department of Health, Education and Welfare for the maintenance of confidentiality in educational research are summarized. Key terms, such as "system of records" are defined and elaborated upon. The responsibilities of the funding agency and its research contractors are enumerated and…

Concern is growing over the problems of freedom of information, individual right to privacy, and automated recordkeeping systems.
