Overview
Secure computation technology enables various statistical analyses using encrypted data while it remains encrypted. NTT has developed a fast secure computation algorithm that uses an encryption scheme called secret sharing. Secure computation can maintain the confidentiality of clinical data or other highly confidential data in the field of medicine and eliminate concern over data leaks.
Features
- Returns only the results of statistical analysis, eliminating the need for confidential data storage.
- Even the system operator cannot browse the data, so data can be used for analysis without concern.
- World’s fastest processing (sorting is at least 100 times faster).
- A variety of statistical analyses available (including medical statistics).
- Microsoft Excel® can be used as the user interface for analysis.
Application scenarios
- Services in which clinical pathology data that is collected and kept by physicians is analyzed and the results made available to researcher on request.
- Implementing secure computation on the cloud would enable cloud services for businesses and media based on analysis of confidential data while maintaining privacy and confidentiality.
- Services for safe use of sensitive data across enterprises in fields such as medicine and finance without the data leaving custody.
