While data sharing brings personalized, convenient, and enriched services to users, it also introduces security risks, including sensitive data leakage and misuse, highlighting the importance of data classification and grading as the foundational pillar of security. This paper presents a cloud-edge collaborative banking data open application scenario, focusing on the critical need for an accurate and automated sensitive data classification and categorization method. The regulatory outpost module addresses this requirement, aiming to enhance the precision and efficiency of data classification. Firstly, regulatory policies impose strict requirements concerning data protection. Secondly, the sheer volume of business and the complexity of the work situation make it impractical to rely on manual experts, as they incur high labor costs and are unable to guarantee significant accuracy. Therefore, we propose a scheme UP-SDCG for automatically classifying and grading financially sensitive structured data. We developed a financial data hierarchical classification library. Additionally, we employed library augmentation technology and implemented a synonym discrimination model. We conducted an experimental analysis using simulation datasets, where UP-SDCG achieved precision surpassing 95%, outperforming the other three comparison models. Moreover, we performed real-world testing in financial institutions, achieving good detection results in customer data, supervision, and additional in personally sensitive information, aligning with application goals. Our ongoing work will extend the model\u2019s capabilities to encompass unstructured data classification and grading, broadening the scope of application.<\/jats:p>","DOI":"10.3390\/fi16030102","type":"journal-article","created":{"date-parts":[[2024,3,18]],"date-time":"2024-03-18T04:25:15Z","timestamp":1710735915000},"page":"102","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["UP-SDCG: A Method of Sensitive Data Classification for Collaborative Edge Computing in Financial Cloud Environment"],"prefix":"10.3390","volume":"16","author":[{"given":"Lijun","family":"Zu","sequence":"first","affiliation":[{"name":"School of Computer Science, Fudan University, Shanghai 200433, China"},{"name":"Institute of Financial Technology, Fudan University, Shanghai 200433, China"},{"name":"China UnionPay Co., Ltd., Shanghai 201210, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenyu","family":"Qi","sequence":"additional","affiliation":[{"name":"Huawei Technologies Co., Ltd., Nanjing 210012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongyi","family":"Li","sequence":"additional","affiliation":[{"name":"School of Computer Science, Fudan University, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohua","family":"Men","sequence":"additional","affiliation":[{"name":"China UnionPay Co., Ltd., Shanghai 201210, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5706-7503","authenticated-orcid":false,"given":"Zhihui","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Computer Science, Fudan University, Shanghai 200433, China"},{"name":"Institute of Financial Technology, Fudan University, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiawei","family":"Ye","sequence":"additional","affiliation":[{"name":"School of Computer Science, Fudan University, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Huawei Technologies Co., Ltd., Nanjing 210012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Seaman, J.
