Abstract: With the digital transformation of the company and the development of archives management to high quality, archives arrangement is particularly important. Checking the integrity and compliance of archives requires a lot of manpower investment, which is inefficient and unable to meet the needs of archives management.In this paper, a method based on multi-modal key verification algorithm is used to build a multi-modal model and algorithm to verify the company's massive archival data to ensure the compliance of archival data. It can replace the manual inspection of each file and improve the efficiency of file inspection.The MATLAB simulation results show that the key check algorithm based on multi-modal has higher judgment accuracy, reduces the influence of subjective factors on the integrity of archives, and realizes the stability of the calculation results. The key check algorithm based on multi-modal can improve the integrity of company archives and shorten the filing time under the massive archives information, which is superior to the previous filing methods.To meet the filing needs of the company's archives.
