大华股份获专利，利用字段标记对图数据库返回结果做脱敏

11月6日，大华股份（002236）的发明专利《一种数据管理方法、设备和计算机可读存储介质》获授权，申请号为CN202310535502.3。

图数据库查询可能返回不同结构的数据，对所有结果按同一套固定字段名处理，难以覆盖多种返回形式。方案先取得待处理结果，再读取各子数据字段携带的脱敏标记，将属性值与预设范围对应。只有符合范围的字段才进入处理步骤。这样，判断某个值能否原样返回的依据跟随字段本身，不必预先限定整条查询结果的类型。

截至此次授权消息披露时，大华股份今年获得的各类专利授权共757项，比上年同期减少29.25%。在2026年上半年，公司研发投入为19.99亿元，同比增长0.74%。企业知识产权记录中，浙江大华技术股份有限公司名下可查到11520条专利信息和1147条著作权信息。
