 As reliance on cloud computing increases among researchers, so do the ethical implications. Among the greatest concerns is ensuring data privacy and security with cloud-based services. For researchers sharing datasets online for collaborative processing and analysis, steps must be taken to ensure only authorized personnel have access to the online data that might contain PII, but also that suitable encryption is used for data transfer and storage, and that the cloud service provider maintains sufficient security to prevent breaches. Further, once research data is uploaded to a third-party cloud provider, attention must be paid to the terms of service for the contracted provider to determine what level of access to the data, if any, might be allowed to advertisers, law enforcement, or other external agents.
