“…As shown in Table 3, the superiority of our proposed method to [14, 17–19, 28] is its blindness. Furthermore, the advantage of our approach over [13, 15, 16, 20–22, 29, 41] is that they use a spatial domain and LSB method to embed the watermark information which might be changed by innocent image processing operations.…”

“…The approach of this class of multipurpose watermarking has been used by researchers to achieve tamper localisation (through fragile watermark) and recovery (through the robust watermark) [27]. In the third class of multipurpose watermarking, robust and fragile watermarks are combined into a hybrid watermark which is then embedded as in the case of a single watermark [28], although, the method of [28] is not blind. Some of the methods of second and third classes of multipurpose watermarking in the literature also use the spatial domain and least significant bit (LSB) method to embed authentication information.…”

Currently, the existing literature on multipurpose watermarking employs multiple watermarks for simultaneous achieving of multiple security objectives. This approach can be problematic since a watermark targeting tampers might fail to detect tampering of another watermark inserted for copyright violation. Moreover, most of the current schemes follow a non‐blind approach where the original watermark is needed for authentication. A question that naturally arises is whether multipurpose watermarking can be realised with the insertion of a single watermark in a blind way or not. The goal of the authors study is to provide an affirmative answer to this important question. They show how a cryptographic primitive called verifiable threshold secret sharing can be used to come up with a generic construction for blind multipurpose watermarking which inserts a single watermark into the host image for simultaneous achieving of copyright protection, authentication, and tamper localisation. The generic property of the proposed scheme provides flexibility for choosing the embedding/extraction of the watermark based on the desired level of fidelity, robustness and capacity. Experimental results are provided to confirm the superiority of their proposed technique as compared to existing approaches.
