    Dynamic Watermarking-Based Integrity Protection of Homomorphically Encrypted Databases – Application to Outsourced Genetic Data

    In this paper, we propose a dynamic database crypto-watermarking scheme that enables a cloud service provider (CSP) to verify the integrity of encrypted databases outsourced by different users. This scheme tak...

    Adapted Quantization Index Modulation for Database Watermarking

    In this paper, we adapt the robust Quantization Index Modulation (QIM) originally proposed by Chen and Wornell for images to the protection of relational databases. In order to embed a bit of the watermark, we...
