Jรถrn Altmann.The Industrial Internet of Things (IIoT) has become a valuable data source for products and services based on advanced data analytics. However, evidence suggests that industries are suffering a significant loss of value creation from insufficient IIoT data sharing. We argue that the limited utilization of the Sensing as a Service business model is caused by the economic and technological characteristics of sensor data, and the corresponding absence of applicable digital rights management models. Therefore, we propose a combined property rights enforcement and pricing model to solve the IIoT data sharing incentive problem.์‚ฐ์—…์šฉ ์‚ฌ๋ฌผ ์ธํ„ฐ๋„ท (IIoT) ๋ฐ์ดํ„ฐ๊ฐ€ ์ œํ’ˆ๊ณผ ์„œ๋น„์Šค๋ฅผ ์œ„ํ•œ ์ค‘์š”ํ•œ ๊ณ ๊ธ‰ ๋ฐ์ดํ„ฐ ์†Œ์Šค๋กœ ์—ฌ๊ฒจ์ง€๊ณ  ์žˆ์ง€๋งŒ, ์—ฌ์ „ํžˆ ์ˆ˜ ๋งŽ์€ ๊ธฐ์—…๋“ค์€ ๋ถˆ์ถฉ๋ถ„ํ•œ ์‚ฐ์—…์šฉ ์‚ฌ๋ฌผ ์ธํ„ฐ๋„ท ๋ฐ์ดํ„ฐ ๊ณต์œ  ์‹œ์Šคํ…œ์œผ๋กœ ์ธํ•˜์—ฌ ๊ณ ์ถฉ์„ ๊ฒช๊ณ  ์žˆ๋‹ค. ๋ฐฉ๋Œ€ํ•œ ๋ถ„๋Ÿ‰์˜ ์‚ฐ์—…์šฉ ๋ฐ์ดํ„ฐ๊ฐ€ ์ œ๋Œ€๋กœ ๊ฑฐ๋ž˜๋˜์ง€ ๋ชปํ•˜๊ณ  ์žˆ์œผ๋ฉฐ, ์ด๋Š” ๋ฐ์ดํ„ฐ์˜ ์ปค๋‹ค๋ž€ ๊ฐ€์น˜ ์†์‹ค๋กœ ์ด์–ด์ง€๊ณ  ์žˆ๋‹ค. ๋ณธ ์—ฐ๊ตฌ์—์„œ๋Š” ์„œ๋น„์Šค๋กœ์„œ์˜ ์„ผ์‹ฑ (Sensing as a Service) ๋น„์ง€๋‹ˆ์Šค ๋ชจ๋ธ์ด ํ•œ์ •์ ์œผ๋กœ ์ ์šฉ๋˜๊ณ  ์žˆ๋Š” ์›์ธ์ด ํ•ด๋‹น ์ •๋ณด์˜ ๊ฒฝ์ œ์ , ๊ธฐ์ˆ ์  ํŠน์ง•๋“ค์„ ๋ฐ˜์˜ํ•˜๋Š” ๋””์ง€ํ„ธ ๊ถŒ๋ฆฌ ์‹œ์Šคํ…œ์˜ ๋ถ€์žฌ์— ๊ธฐ์ธํ•œ๋‹ค๊ณ  ๋ณด๊ณ  ์žˆ๋‹ค. ๋”ฐ๋ผ์„œ ๋ณธ ์—ฐ๊ตฌ์—์„œ๋Š” ์‚ฐ์—…์šฉ ์‚ฌ๋ฌผ ์ธํ„ฐ๋„ท ๋ฐ์ดํ„ฐ์— ๋Œ€ํ•œ ์ง€์ ์žฌ์‚ฐ๊ถŒ ์ง‘ํ–‰ ์‹œ์Šคํ…œ๊ณผ ๋ฐ์ดํ„ฐ ๊ฐ€๊ฒฉ์‚ฐ์ • ๋ชจ๋ธ์„ ์ œ์•ˆํ•˜์—ฌ ์‚ฐ์—…์šฉ ์‚ฌ๋ฌผ ์ธํ„ฐ๋„ท ๋ฐ์ดํ„ฐ ๊ณต์œ  ์ธ์„ผํ‹ฐ๋ธŒ ๋ฌธ์ œ๋ฅผ ํ•ด๊ฒฐํ•˜๊ณ ์ž ํ•œ๋‹ค.1 Introduction 1 1.1 Background 1 1.2 Problem Description 6 1.3 Research Objective and Question 8 1.4 Methodology 8 1.5 Contributions 9 1.6 Structure 10 2 Literature Review 11 2.1 Sensing as a Service 11 2.2 Economic Characteristics of IIoT Data 14 2.2.1 Property Rights of Data 18 2.2.2 Licensing of IIoT Data 23 2.3 IIoT Data Marketplaces 25 2.3.1 Use-cases and Value Propositions 30 2.3.2 Market Structures and Pricing Models 34 2.4 Digital Rights Management for IIoT 36 3 Model 44 3.1 Assumptions 45 3.2 Watermarking Technique 47 3.2.1 Function 48 3.2.2 Example 50 3.2.3 Robustness 51 3.3 Economic Reasoning 54 3.3.1 The Quality Gap 55 3.3.2 Cost of Watermarking (CoW) 57 3.3.3 Cost of Attacking (CoA) 58 4 Analytical Analysis 60 4.1 Equilibrium Between CoW and CoA 60 4.2 Determining the Optimal Quality Gap 62 4.3 Applicability of the Quality Gap Function 64 5 Conclusion 66 5.1 Summary 66 5.2 Discussion 66 6 Limitations and Future Research 68 References 70 Abstract (Korean) 79Maste
