One of the issues in collaborative MR is permission and rights control that defines which user can access which virtual object. A user may define access rights for other users to access the virtual objects created by her/him, which might enable the other users to manipulate the existing virtual object, delete them, or even steal them. For maintaining accountability in the collaborative world, each activity of each user should be maintained against each object. Hence, an activity provenance mechanism is required for a collaborative MR environment, which can be used to identify the culprit. In this paper, a secure activity provenance mechanism for collaborative MR environments is proposed which utilizes blockchain technologies to maintain the integrity of the provenance data. The proposed scheme is implemented on a consortium blockchain using Hyperledger Fabric as a proof of concept. The presented mechanism is also evaluated using metrics throughput and latency and the results confirm that the proposed solution is best suited for maintaining accountability in a collaborative mixed reality network.","PeriodicalId":142898,"journal":{"name":"2023 20th Learning and Technology Conference (L&T)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126712139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patients need to integrate and manage their medical data continuously. Personal Health Record (PHR) is introduced as a solution for managing their health information. It gives patients ownership over their medical data and provides physicians with realignment data. However, it does not achieve reliability, traceability, trust, nor security of patient control. Centralization of any data is vulnerable to the problem of hacking and single failure in addition to control from one organization. So, the centralization of data is the common problem that all current healthcare systems suffer from. Even in the Metaverse world, the application of Metaverse in healthcare services loses users’ privacy as one of its challenges. In this study, we suggest using blockchain in healthcare to improve security and privacy in medical records. The proposed system employs the advantages of blockchain technology to give patients full control over their data with low throughput, high overhead, and latency. We present a security analysis of our suggested architecture as well as blockchain issues in healthcare systems.","PeriodicalId":142898,"journal":{"name":"2023 20th Learning and Technology Conference (L&T)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115270910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
