Anonymise IMSI

In-flight data anonymisation is a key feature for solutions that process sensitive data. Joule provides this feature through a custom encryption obfuscator.

---

This example performs field level anonymisation on the customer IMSI using RSA encryption. Encryption keys are dynamically generated from a random initialisation vector with the resulting keys stored in a user defined directory. Encryption processor Documentation can be found here.

Use case configuration

File: app-anonymisation.env

SOURCEFILE=conf/sources/mobileSimulatedStream.yaml
ENGINEFILE=conf/usecases/anonymisation/mobileEventAnonymisation.yaml
PUBLISHFILE=conf/publishers/anonymisedMobileEventFile.yaml

Pipeline configuration

This pipeline will encrypt the event IMSI using sytem generated keys.

processing unit:
  pipeline:
    - filter:
          expression: "(imsi !== null ) ? true : false;"
         
    - obfuscation:

        fields:
          imsi:

              decrypt: false
