Abstract
En 中文
• We propose a dynamic reversible data hiding method for relational databases using attribute value ordering. • The proposed method employs dynamic grouping and leverages attribute value sorting to enhance the data embedding capacity while minimizing distortion. • To achieve a dynamical embedding, the database is split into multiple attribute groups, and each group is dynamically embedded.
Keywords:
