###### Abstract
However, none of the above-mentioned digital property rights management mechanisms integrate the operation of the cash flow system, and naturally cannot reflect its feasibility. Therefore, this article integrates cash flow management into our digital rights management regarding comprehensive digital collections and promotes transparency of collections, the heart of museums. Apart from the practice of equality, the production of images provides an extension of museum collections and serves as a carrier of culture. The circulation of copied images creates richer and more diverse ways of use [23]. In 2017, Ma proposed a common, flexible, and extendable solution for variant DRM scenes, and can support rapid and customized development [24]. [PERSON] proposed a decentralized architectural model, which makes use of digital rights management to enforce access control over personal information [25]. [PERSON] et al. [26] concluded the open research issues and future directions towards securing IoT. Including the use of blockchain to address security challenges in IoT, and the implications of IoT deployment in 5G and beyond. Therefore, the first focus of digital rights management is how to achieve proper authorization. Generally, the authorization mode of digital collections in museums is divided into the following three methods:  
1. Direct authorization model of museum digitized collections  
The direct authorization model is a model in which the museum, as the authorized party, signs a contract with the authorized party to authorize it to use the digital resources of the collections. The museum collects cultural relics, produces digital content, encrypts and encapsulates, authorizes the identity verification and makes remittance notices, authorizes remittances royalties' feedback, and finally operates the key authorization process. The authorization model process is shown in Figure 1. The National Museum of the Netherlands and the British Museum, as well as the National Palace Museum in Taipei in Taiwan, are typical examples of the direct authorization model. Under this authorization model, the authorized party often directly participates in the use of the digital image resources of cultural relics by third-party manufacturers. The advantage is that it is not only conducive to the museum as the authorized party to promptly understand the development of digital image resources, but is also given an in-depth understanding of the connotations of the collection by the relevant departments

However, the shortcomings of this authorization model are also obvious. Because the authorized party is a state-owned museum, the nature of its public welfare institutions often makes it limited in authorization methods, scope, personnel incentives, and so on, so it can easily lead to insufficient responses to market demand and changes. 2 Proxy authorization model of museum digitized collections  
The proxy authorization model refers to the model in which the museum does not directly act as the authorized subject, but entrusts an agent or an authorization platform as an intermediary, authorizes through a contract with the authorized party, and finally uses the digital resources of the collection in the manner agreed to in the contract. In this model, there will be two authorization behaviors: The first time is the authorization by the museum to the agent or the authorization platform, and the second time is the authorization by the agent or the authorization platform to the third party. The process of this type of authorization mode is shown in Figure 2. The Louvre Museum in France and the Solomon R Guggenheim Museum in the United States are typical representatives of this authorization model.
