“…Obtaining the proof gets harder on long-term stored documents such as patient or financial records, contracts, and governmental regulations, etc. [20,21]. It is complicated to investigate authorizations of multiple operations on a document such as contract signing or patient history over these intervals varying from months to decades.…”

The layered structure provides comparative and integrated analysis of the authorization mechanisms. The incremental authorization structure would be a guide for implementations in that each layer presents the scope of authorization by providing analysis on deficiencies and the methods of solution. An institutional authorization mechanism on documents is also proposed. The proposed mechanism suggests and implements an authorization mechanism to enclose authorization restrictions in institutional regulations.

“…For instance, hospital information system addresses security problems and provides confidentiality, integrity and authentication via watermarking. Watermarking applications for medical purposes have been extensively investigated with reference to their security (Arsalan et al 2012;Fakhari et al 2011;Ko et al 2011).…”

In the biomedical and healthcare fields, the ownership protection of the outsourced data is becoming a challenging issue in sharing the data between data owners and data mining experts to extract hidden knowledge and patterns. Watermarking has been proved as a rightprotection mechanism that provides detectable evidence for the legal ownership of a shared dataset, without compromising its usability under a wide range of data mining for digital data in different formats such as audio, video, image, relational database, text and software. Time series biomedical data such as Electroencephalography (EEG) or Electrocardiography (ECG) is valuable and costly in healthcare, which need to have owner protection when sharing or transmission in data mining application. However, this issue related to kind of data has only been investigated in little previous research as its characteristics and requirements. This paper proposes an optimized watermarking scheme to protect ownership for biomedical and healthcare systems in data mining. To achieve the highest possible robustness without losing watermark transparency, Particle Swarm Optimization (PSO) technique is used to optimize quantization steps to find a suitable one. Experimental results on EEG data show that the proposed scheme provides good imperceptibility and more robust against various signal processing techniques and common attacks such as noise addition, low-pass filtering, and resampling.

“…The authors proposed a specific multicast fingerprinting solution based on the digital watermarking mechanism. Therefore, the illegal distribution of the medical image can be tracked by extracting the watermark message [2,[9][10][11]. Since none of encryption and watermarking alone can provide the protection.…”
