Method for extracting spacial position feature value of fixed length from information

Abstract

The invention relates to a method used for extracting fixed-length spatial location characteristic numerals from information in the information security techniques, which comprises the following steps: parameter information of a fixed-length spatial location is obtained; decimal expression values of the information in a code table are obtained by a symbol set in a computer; a converting method from the information to the spatial location is obtained; the fixed-length spatial location characteristic numerals are analyzed; and the input information is processed by the computer or other equipments with computing and storing functions, thus obtaining the spatial location characteristic numerals which are corresponding to the input information. The method can simply, intuitively and efficiently extract the unique fixed-length spatial location characteristic numeral which are corresponding to the information from the information; by the method, the same effect can be achieved by judging the spatial location characteristic numerals when the user judges whether the information is modified in a transmission process; and as the spatial location characteristic numerals have fixed length and certain regularity, the efficiency is greatly improved, when the processing of the information including encryption, identification and judgement is carried out, and the method has strong practicability.

Description

Technical field [0001] The present invention relates to information security technology, in particular to a method for extracting a fixed-length spatial position characteristic value from information. Background technique [0002] With the continuous development of computer technology and the Internet, computer networks have become an important feature of the information age. The network is the product of computer technology and communication technology, and was developed in response to the requirements of the society for information sharing and information transmission. At present, computer networks have become a very important part of people's lives. They are widely used in Internet chatting, information transmission, national defense, telecommunications, banking, and broadcasting. [0003] Because the network is so widely used and plays a very important role in life, the security of network information has become an important issue that people cannot ignore. The current networ...
