Methods and Algorithms of Input Information Protection in Electronic Document Processing Systems
Abstract
The efficiency of various nature redundancy use for data reliability provision has been proved; methods, models, algorithms and software provision of information reliability on the basis of expert systems, knowledge bases, logic control criteria, compression methods and data coding, DB structures modeling and application in SEDP have been developed. The method of information reliability provision based on the structurally - technological redundancy, using criteria of the logic control, expert systems and knowledge bases is offered. Algorithms of data reliability provision based on statistical and dictionary methods of compression and coding, semi-adapted and the adapted models of an arithmetic code have been developed. Models and three-level architecture of DB structure and operative methods of information reliability provision, using time and program redundancy have been developed. In a new problem statement of the various errors account in information the problem decision techniques have been obtained and the data processing program system and information reliability provision with object-oriented programming technology has been developed.
