Introduction

Location data can reveal sensitive information about persons, which leads to a privacy breach. When anonymizing raw location data, a balance needs to be achieved between the user anonymity level and utility of the anonymized data.

The Real-Time Anonymizer customizable pipeline template provides a simple way to customize, configure, and deploy the required real-time anonymization on the HERE platform. The Real-Time Anonymizer contains a set of algorithms for performing use case specific anonymization of real-time location data, including the following features:

  • Loading real-time location data
  • Configure the anonymization strategy and accompanying parameters
  • Perform anonymization of location data with specific method and parameters
  • Output anonymized real-time location data

What Is the Real-Time Anonymizer

HERE platform pipelines are scalable processing blocks that perform a specific task (that is map matching positions or pooling multiple data sources), working with location data in HERE Catalogs.

The Real-Time Anonymizer works with streaming layers (queues that stream data to data consumers) only. Versioned, volatile and index layers are not compatible with this pipeline.

The Real-Time Anonymizer supports you with the following:

  • loading and outputting real-time location data from HERE platform streaming layers
  • use-case specific anonymization of real-time location data
  • configuration of input/output data, anonymization method and data requirements for use case/s
  • basic validation of input data against configure use-case specific requirements
  • statistics on completed anonymization

The Real-Time Anonymizer is a streaming pipeline, ingesting data from a raw location data streaming layer and outputting the anonymized data to a separate streaming layer. The input streaming layer provides a queue that streams real-time data to data consumers. The output streaming layer contains real-time anonymized data that can be read by multiple consumers.

HERE Customizable Pipeline Templates provide a simple way for deploying custom, configurable pipelines on the HERE platform. They can be deployed as part of your own workflow without needing to write any code. Each template is designed to perform a specific task and can be customized to accommodate your particular use case. The Real-Time Anonymizer is made available as a template for ease of deployment.

Why Use the Real-Time Anonymizer

Primarily, the Real-Time Anonymizer helps you with the following objectives:

  • systematically anonymize real-time location datasets for a specific use case
  • output the anonymized location data on the HERE platform

Additionally, you can use the Real-Time Anonymizer to process location data for the following use case.

Traffic Information

You can use vehicle probe data points to derive traffic information. With the Real-Time Anonymizer, your program can optimally anonymize raw probe points. This way, the anonymized data offers maximum value for deriving traffic information while also protecting persons against the privacy breach.
