title = "A Blockchain and Proxy Re-encryption-based Framework for Construction Cost Information Management",
abstract = "Due to the possibility of data tampering in a centralized paradigm, current cost information management platforms are concerned with data accountability (i.e., data integrity and traceability). Blockchain is a promising technology that offers decentralized data storage with immutable and traceable data. However, the blockchain's transparency contradicts the cost data's requirement of confidentiality. In order to maintain accountability and confidentiality of construction cost information, this study provides a new approach based on blockchain and proxy re-encryption (PRE), including a cost data model for blockchain recording and a PRE-based method for cost data access management among project members. An illustrative scenario is used to show the feasibility of the proposed approach in securing construction cost information.",
