Abstract
In one example, a method of protecting customer data in a networked system comprises collecting sensor data available at sensor nodes within a sensor network in communication with a service data platform over a network. The method includes encrypting the sensor data using a certified public key associated with a customer key-pair, the sensor data representing the customer data associated with sensitive identification information. The sensor data is cryptographically signed with a device private key. The method includes transporting the encrypted sensor data to the service data platform for storage, and decrypting at the service data platform, the encrypted sensor data using a private key sharing scheme that reconstructs the private key associated with the customer key-pair using a first share and a password encrypted second share, the first share assigned to the service data platform and the password encrypted second share assigned to a customer of the customer key-pair.
