B) when a bidder uploads a bid file in the bidding system, the system acquires a unique identification code of the bid file through an MD5 algorithm and stores and encrypts the unique identification code along with the file, the bidding system calculates the unique identification code of the bid file through an MD5 algorithm again when opening the bid, the unique identification code of the file is completely consistent, the file when the bidder puts the bid is completely consistent with a bidding site file, serial modification and malicious tampering of a hacker technology between a tenderer and the bidder do not occur midway, the system decrypts the bid file, and a comparison result of the file identification code is marked;
the MD5 algorithm, a widely used cryptographic hash function, generates a 128-bit (16-byte) hash value to ensure the integrity of the message transmission. The embodiment preferably uses the MD5 algorithm to obtain the unique identification code of the bid document.
C) And obtaining a bidding safety auditing result according to the marking results in the steps A) and B).
Step 3, constructing a matching auditing model, analyzing the catalog of the bidding document to obtain the matching of the bidding request content and the contents of the bidding document:
the matching auditing model calculates the matching of the bidding file name and the bidding file directory by character matching, and the step 3 comprises the following steps:
according to the requirements of the bidding documents, respectively extracting the keywords alpha in the bidding document names1,α2,...,αmForm a keyword list [ alpha ] of the file names to be bid on1,α2,...,αm]In which α isi≠αjWhen i is not equal to j and the keyword label i, j belongs to {1,2, 3.., m }, in specific implementation, the importance sequence of each file can be input according to pre-obtained evaluation expert experience, and a corresponding file preference weight list [ k ] is calculated by utilizing an analytic hierarchy process1,k2,...,km]Wherein k is1+k2+...+km1 is ═ 1; wherein m is the number of keywords in the bidding document name; the analytic hierarchy process is realized in the prior art, and the invention is not repeated;
according to the requirement of the bidding document, extracting keywords beta of each grade title in the contents of the bidding document1,β2,...,βnForm a keyword list [ beta ] of the bidding catalog1,β2,...,βn]Wherein beta isi≠βjWhen i is not equal to j and i, j belongs to {1,2, 3.,. n }, inputting the importance sequence of each title according to the pre-obtained experience of the evaluation expert, and calculating a corresponding title preference weight list [ l ] by utilizing an analytic hierarchy process1,l2,...,ln]Wherein l is1+l2+...+ln1 is ═ 1; wherein n is the number of keywords in the bidding catalog;
