Abstract： Due to the complexity of large-scale fiscal data composition，the data recovery rate is low.Therefore， this articledesigns acolaborativecontrol method foroperationand inspection sites based on wireless ad hocnetwork. Firstly，itidentifiesthesensitivityoffinancial datathrough cloudcomputing，quantifies sensitivityusing information gain，and ensures thatcritical data is protected with emphasis.Secondly，basedon attributeencryptionalgorithms， dynamic encryptionkeysare generatedtoencrypt plaintext financial data.Finalydesigna hierarchical secure storage modeltoensure the secure storage and efcientaccess ofencrypted financialdata.Whenreadingdata，due tothe data being split into discontinuous blocks and encrypted for storage，only legitimateusers who obtain allthe split blocks andapply the corrct decryption rules canrecover the originaldata，thusachieving gradedand securestorage of largescalefinancial data.Theexperimental results showthatthe average data recoveryrateof this design method is as high as 94% ， proving thatthe designed storage method can maintain a high data recovery rate under different data volumes， effectively reducing therisk of data damage orloss.
