1. A method of verifying an authenticity of declaration information, comprising:
acquiring a machine-detected radiation image obtained by scanning a container loaded with an article;
acquiring a declaration information for declaring the article in the container;
performing an identification on an image information of the article in the machine-detected radiation image to obtain an image feature corresponding to the machine-detected radiation image;
performing an identification on a text information of the article in the declaration information to obtain a text feature corresponding to the declaration information, wherein the text feature is configured to represent a declaration category to which the article in the declaration information belongs;
screening a declaration category of the article in the container by taking the image feature as an input information and the text feature as an external introduction feature; and
determining that the declaration information is in doubt when a declaration category of at least one article in the container does not belong to a declaration category in the declaration information,
wherein the text feature comprises text feature vectors corresponding to N2 articles in the declaration information, respectively, wherein N2 is an integer greater than or equal to 1,
wherein the performing an identification on a text information of the article in the declaration information to obtain a text feature corresponding to the declaration information comprises:
extracting a name information and a specification model information of each article in the declaration information;
for each article, processing the name information into a first statement, and processing the specification model information into a second statement;
determining the first statement and the second statement corresponding to a same article as an input of a text feature extraction projection module, and classifying the declaration category to which the article belongs using the text feature extraction projection module; and
determining an output result of the text feature extraction projection module for each article category as the text feature vector corresponding to the article; wherein N2 text feature vectors are correspondingly obtained for N2 articles.
