SYSTEM FOR ACCESSING DATA

摘要

computer systems. SUBSTANCE: method involves introducing new modules and links between functional nodes for building multilevel authorized data access control and recording user access to storage areas. Multilevel data access is created depending on password code entered by user. Deleting data from memory is carried out after the user finished working with data so that the next user could not read the data retained in memory after the previous user of higher access authorization level has logged out. Self-test mode is realized to check device reading data from electronic protection key unit. EFFECT: enhanced effectiveness of data protection from unauthorized access. 3 cl, 1 dwg
