###### Abstract
For example, the sea area around the National Museum of Marine Biology and Aquarium, located in the Kenting National Park in southern Taiwan, is a typical marine environment intersection, covering the estuary area, sandy mud bottom, reef shores, and other habitats. [PERSON] et al. [7] studied and integrated the fish species in the sub-tidal zone around the National Museum of Marine Biology and Aquarium, which provides a constant monitoring and conservation research platform for the aquatic environment and biodiversity. The museum has also carried out the image management collection of collection resources [8], but how to use these valuable research resources of the museum through the appropriate preservation, management, authorization, and promote social education is an extremely important challenge. In recent years, under the concept of \"activating and reproducing collections\", museums spread a huge amount of knowledge and culture to visitors with their rich collections, such as artworks, crafts, biological specimens, texts, drawings, paintings, photos, maps, movies, and sound recordings. Museums all over the world take marketization, digitization, diversification, and popularization as their development direction. Their development and utilization of digital image resources in the collections, via different authorization models, are widely praised by society. The cultural industry chain is divided into four links: Research and development, production, circulation, and consumption. With the development over time, the term \"authorization\" has been widely used in the cultural industry, and its connotation and extension have also been continuously expanded, and gradually valued by museums. At present, there are two views on the definition of digital image authorization of museum collections: One view is that authorization refers to the process by which the museum grants the digital image of cultural relics owned or managed by the museum as the subject matter to the authorized person in the form of a contract; another view is that authorization is mainly the process of transaction and management of related intellectual property rights. The ultimate goal of museums' digital authorization of collections is to increase economic benefits based on spreading culture and exerting its educational function. However, due to various reasons, most people may not be able to visit their favorite museums one by one due to time and space constraints. For example, since the outbreak of the COVID-19 at the beginning of this year (2020), the American Alliance of Museums (AAM) recently stated that nearly one-third of museums in the United States may be permanently closed, and pointed out that museum operations are facing \"extreme financial difficulties\" [9]. Therefore, determining how to protect museum collections and effectively use these collection resources to maintain the operation of the museum is a critical topic for consideration by museum operators. Due to the fading of museum collections, while promoting social education, we must strive to preserve them. Digitizing collections is a feasible way. On the other hand, in order to maintain the sustainable operation of museums, it is important to manage the property rights of museum collections after digitization. Copyright provides a bridge between art and commerce because we need to protect the collections. In the past, using watermarking technology to achieve digital property management has been a mature technology [10; 11; 12]. Digital rights management is always inseparable from cryptographic technology [13; 14; 15; 16]. Up to now, watermarks are combined with smart contract technology to realize digital property management [17]. In recent years, more scholars have used the characteristics of decentralization, non-tampering, traceability, and blockchain openness to solve the application problems of digital rights management, a process that has expanded rapidly [17; 18; 19; 20; 21; 22].
