Data Fields Fuzzifier

This implementation offers as a service the ability to fuzzify a specific data field before this field is disclosed to 3rd parties, in order to enhance privacy aspects. A configuration step is necessary initially in order to define the input data fields and the range of this fuzzification per data field, given that it is case specific and there is a trade-off between how much one can fuzzify data and the accuracy of the provided information of the 3rd party service. As an example, if restaurant recommendations are needed by providing a fuzzified user location, this fuzzification should not be larger than 500 metres, in order to provide the user with meaningful suggestions. Both the configuration and usage calls are available via Node-RED flows.

Endpoint: To be provided upon registration
JSON example: JSON for configuration {"data":{"latitude":{"privacy_level":"low","range":"0.0005"},"longitude":{"privacy_level":"medium","range":"0.5"}}} JSON for usage of fuzzification { "username":"myUsername", "latitude":"51.532379", "longitude":"-0.137874" }
JSON schema: The JSON schema depends on the format of the data fields inserted upon configuration. The only static field is username, for the service username. For the example above the user has defined two fields to fuzzify (latitude,longitude) thus the schema is the following: { "$schema": "", "type": "object", "properties": { "username": { "type": "string" }, "latitude": { "type": "string" }, "longitude": { "type": "string" } }, "required": [ "username", "latitude", "longitude" ] })
