Hologram printing technology is a technology that outputs digital holographic printing contents on a flat surface of the real world. Since the printed holographic printing content shows different images depending on the observer's point of view on a flat object, a three-dimensional shape can be displayed without a separate device. However, the source of digital holographic printing content requires about 10 TB of data capacity to output A4 paper size. Therefore, in order to construct a market for trading original digital holographic printing contents, a technology for stably transmitting large amounts of data is required. In addition, if an act beyond the scope and authority of digital holographic printing content is allowed, financial damage may occur due to illegal copying and undue gain. To solve this problem, a market and DRM technology are needed to safely and efficiently transmit large amounts of digital data while stably transmitting it. In this study, proxy re-encryption technology was used to design a system that satisfies these requirements, and in this process, the required information and system model were designed, and a protocol to share data safely was designed. Proxy re-encryption technology is a technology that can safely and efficiently deliver data without exposing data and encryption/decryption keys to unauthorized users, and is suitable for communication and server environments that are not completely trusted. In this study, based on such proxy re-encryption technology, it is expected that the foundation for safe and efficient transaction of digital holographic printing contents will be prepared, and furthermore, it will provide a driving force for the growth of the holographic printing market.
