"Open Spime allows everyone to record, encrypt, send, store, manage, and visualize data, for FREE. What you will need to use our technology is just a SpimeID, which is an encrypted identification number.
During the collection of sensor data the SpimeIDs are validated, and accrue to a relevant and authoritative volume of data. You are in control of how you choose to display the data you collect, privately or publicly. In case of public data, the OpenSpime servers enable the anonymous aggregation of information from multiple sensors, achieving a view of unprecedented clarity and power."
