Abstract

The invention discloses a Hash fingerprint based on position information and DNA information and a construction method and application thereof. The Hash fingerprint of the invention is obtained by collecting plant geographic position information and DNA characteristic coding information, digitally marking the characteristic information and constructing the Hash fingerprint. The method comprises the following steps of: firstly, carrying out one-way Hash code (an irreversible mapping from plaintext to ciphertext) on the plant geographic position information (obtained through a global positioningsystem) and DNA information, and storing and encrypting the one-way Hash code, the process only encrypts, not decrypts, any length of the input after the change to a fixed length of the output. The algorithm of the invention can extract the traceability characteristic information of the plant according to the difference of the position information and the DNA information of the plant, and carry out the Hash fingerprint identification, and the identification rate is high.

Description

technical field [0001] The invention belongs to the technical field of plant information acquisition, traceability and identification, and specifically relates to a Hash fingerprint based on location information and DNA information, a construction method and application thereof. Background technique [0002] Hash table (Hash table, also called hash table) is a data structure that is directly accessed according to the key value (Key value). That is, it accesses records by mapping key values ​​to a location in the table to speed up lookups. This mapping function is called a hash function, and the array storing the records is called a hash table. Geographic information and remote sensing systems plan locations through maps. Both agriculturalists and geographic research are inseparable from images. Saving images and their analysis results will be of great help to future research. Through the image retrieval system, you can easily find the required geographic image information....
