As enterprises grow in scale and business becomes increasingly intricate, digitalization has emerged as a pivotal factor in enhancing financial operational capabilities and management efficiency. Nevertheless, the sheer volume of financial data and the interspersed presence of anomalies pose significant obstacles to this digital transformation. To address these challenges, we introduce a cloud computing-based digital financial management framework. This approach leverages serialization techniques to efficiently extract data characteristics, harnessing the compression and filtering capabilities of cloud computing to streamline data storage and access procedures. Experimental evidence demonstrates that this method effectively minimizes data errors while bolstering security, thereby serving as a robust foundation for the digitalization of enterprise financial management.
