In this paper, we focus on additive attacks. We extend a conventional image-based relational data watermarking scheme by creating a non-colluded backup of the data owner marks, the so-called secondary marks positions. The technique we propose is able to identify the data owner beyond any doubt. %G English %Z TC 8 %Z WG 8.9 %2 https://inria.hal.science/hal-03408432/document %2 https://inria.hal.science/hal-03408432/file/493186_1_En_12_Chapter.pdf %L hal-03408432 %U https://inria.hal.science/hal-03408432 %~ SHS %~ IFIP %~ IFIP-TC %~ IFIP-LNBIP %~ IFIP-WG %~ IFIP-TC8 %~ IFIP-WG8-9 %~ IFIP-CONFENIS %~ IFIP-LNBIP-375
