Data Processing & Filtering

Data processing is a crucial step in the eDiscovery process for everyone involved. It involves organising, filtering, and preparing all relevant documents and ESI for the review and analysis phases. Here the transformation of unstructured data into structured data occurs before uploading to a document review platform. This ensures the complete integrity and compliance of all involved data with legal requirements. 

Our Process  

During this stage of the eDiscovery process the steps are as follows:  

Step 1: Data Preservation & Collection 

Once our expert team have identified the data sources, preservation is vital. The protection of all meta-data is paramount because it is essential that all data remains untouched and untampered, as this can make or break a case.   

Once this stage is complete, we will evaluate the best approach to collect your data and devices. This can include the following methods: 

  • Onsite Collection 
  • Remote Collection (Download through an intranet) 
  • SFTP or Secure file transfer protocol  
  • Pulse Box (CYFORs creation) 
  • Secure CYFOR courier  
  • Postman or Drop Off 
Step 2: Data Filtering & Reduction 

Data set reduction is key here allowing for a streamlined process to be achieved. Applying accurate filtering methods allows for irrelevant data to be entirely removed. This may be achieved through running key word, data, custodian and file type searches. 

Step 3: De Duplication  

De-duplication eliminates duplicate copies of files, messages, and emails across all datasets. Technology Assisted Review (TAR) and specific algorithms further identify duplicates, retaining only singular documents. 

Our priority is to gather all necessary data for review before processing and uploading it to our document review platform. This is done efficiently and so, adheres to legal deadlines and provides a user-friendly review experience. All whilst allowing its user to analyse and organise their data through specific metadata filtering.  

It is crucial to understand the entire data processing cycle, complying with all legal obligations to ensure defensibility throughout the process, maintaining accuracy and efficiency throughout.
