Abstract Integrity is an important index of document inspection in power sector, which is of great significance to document management and later search. However, the integrity of documents in the power sector is generally poor, which cannot meet the requirements of comprehensive inspection. Multi‐modal key method can analyze the integrity of enterprise archives from multiple angles, not only analyze the data integrity of archives, but also comprehensively judge other attributes of archives, which makes the analysis results more comprehensive. Aiming at the problem that the integrity of archives cannot be judged accurately in the filing process of electric power enterprises, a key verification algorithm based on multi‐modality is proposed. Firstly, the multi‐modal analysis of archives information data is carried out, and the enterprise archives archiving data set is constructed, and the legitimacy of the data set is verified; Using multi‐modal theory, the archives of electric power enterprises are divided into modal subsets, and each modal subset chooses the key verification algorithm; Finally, under the guidance of multimodal theory, modal subsets can accurately archive files. MATLAB simulation results show that the key check algorithm based on multi‐modality can improve the integrity of enterprise archives and shorten the archiving time under massive archives information, which is superior to previous archiving methods and meets the archiving needs of power enterprises. Therefore, the algorithm proposed in this paper is more reasonable, can simplify the document data, reduce the complexity of analysis, and is suitable for massive document analysis.
