Privacy-Preserving Technology for Secure Utilization of Sensor Data (Extended Abstract)
As the number of scenarios for utilizing sensor data from home appliances, privacy issues such as leakage of private information from sensor data are arising. In this paper, we introduce a new technology, partial decryption, which enables parts of the data to be masked while still encrypted, so other data can be substituted or the encryption key can be changed.
