Blockchain-Empowered Lifecycle Management for AI-Generated Content
(AIGC) Products in Edge Networks
Abstract
The rapid development of Artificial Intelligence-Generated Content
(AIGC) has brought daunting challenges regarding service latency,
security, and trustworthiness. Recently, researchers presented the edge
AIGC paradigm, effectively optimize the service latency by distributing
AIGC services to edge devices. However, AIGC products are still
unprotected and vulnerable to tampering and plagiarization. Moreover, as
a kind of online non-fungible digital property, the free circulation of
AIGC products is hindered by the lack of trustworthiness in open
networks. In this article, for the first time, we present a
blockchain-empowered framework to manage the lifecycle of edge AIGC
products. Specifically, leveraging fraud proof, we first propose a
protocol to protect the ownership and copyright of AIGC, called
Proof-of-AIGC. Then, we design an incentive mechanism to guarantee the
legitimate and timely executions of the funds-AIGC ownership exchanges
among anonymous users. Furthermore, we build a multi-weight subjective
logic-based reputation scheme, with which AIGC producers can determine
which edge service provider is trustworthy and reliable to handle their
services. Through numerical results, the superiority of the proposed
approach is demonstrated. Last but not least, we discuss important open
directions for further research.
