A use case of our technology.
PeacefulHealth is a small health insurance company that partnered up with Cloudly, a cloud service provider. To protect privacy of its clients' data, PeacefulHealth encrypts information before storing it with Cloudly. However, PeacefulHealth also wants Cloudly to process clients' data upon request. "Process" could mean, for example, do statistical analysis of data, or search and retrieve information relevant to a particular client, etc. Traditionally, this is done by submitting a request to Cloudly for processing information. Cloudly will then decrypt the database (or part of it), process unencrypted data as requested and provide a response to PeacefulHealth.
With our technology, Cloudly would process data without decrypting any part of the database and send the result(s) to PeacefulHealth for decryption.
The advantages of our technology are:
- Data holder can store information in encrypted form, so even if storage provider has a security breach, intruders will not get a hold of the actual data.
- Storage provider never has access to the actual (unencrypted) data.
- Storage provider does not know search parameters when queried. This is called private information retrieval.
