Software development test data security verification method based on block chain

Abstract

The invention relates to the technical field of data transmission, in particular to a software development test data security verification method based on a block chain, and the method comprises the steps: obtaining each character string sequence of a user transaction software platform; constructing a lexical item singular factor of each lexical item, and calculating a unique division weight of each character string sequence; constructing a reliable feature vector of each lexical item of the unique data sequence and calculating a non-confidence factor and a reliable saliency coefficient; adopting a K-means algorithm to extract each cluster from all lexical items in the unique data sequence; obtaining abstract data to generate signature data; and transmitting the digital signature and the user transaction software platform data to the block chain to complete security verification of the user transaction software platform data. According to the invention, the optimized security verification of the digital signature of the user transaction software platform can be realized, and the security of the to-be-transmitted data of the user transaction software platform is improved.
