eDiscovery Processing

Data-cataloging, error-checking and smart indexing.

eDiscovery data processing, sometimes referred to as ESI processing, is when collected data undergoes cataloging, error-checking and indexing. It takes the data that was gathered from various people and systems and prepares it for the next step. It also involves loading the data into a review hosting platform or document repository so attorneys can more efficiently perform legal document review. It is a necessary and crucial step in the overall eDiscovery process.

A Long-Time Trusted Source for eDiscovery Data Processing

Processing data for eDiscovery since 2002.

Indeed, BIA has been on the forefront of ESI Processing for the eDiscovery industry. We invented several specialized methods that are now widely adopted in eDiscovery data processing systems, such as the way mailhashes are calculated and ensuring tamper-evident methods are used for data collections with validation certificates at the time of data ingestion.

And since we harness the cloud — using both MS Azure and Amazon Web Services (AWS), which are immensely secure and scalable infrastructures — BIA eDiscovery processing has the power to move huge amounts of data through our workflows at one time, with more accuracy than any other eDiscovery data processor.

The Benefits of BIA's eDiscovery Processing

  • Accurate document fingerprinting using multiple hashing methods
  • Identification of email and chat threads, across and within custodian data sets
  • Secure data flow channels with tamper-evident checks
  • Multiple levels of virus and malware scanning to protect client systems
  • Over 40 automated error-checks to maintain data integrity
  • Oversight by certified technicians with years of data processing experience

Preparing eDiscovery Data for Legal Review

Reduce data noise by checking for errors and performing pre-analytics.

The eDiscovery data processing phase includes a specialized workflow and programmatic tasks to process data, such as documents, email threads and database records. It ensures that attorneys and legal professionals can conduct a more effective legal document review.

BIA’s eDiscovery data processing uses accepted technology and leverages methods that will ensure evidentiary integrity is maintained. Once data has gone through our software and processes, you know you can rely on its accuracy for review and analysis.

Accepted eDiscovery data processing workflow:

  • Filter and prepare data for industry-standard review platforms
  • Preserve forensic integrity of collected data
  • Identify non-relevant system files and duplicate items
  • Use mature and well-tested software

The Process of eDiscovery Processing


Diligent and disciplined quality control that is executed across the many technical tasks run against the ingested and processed data.

Ensuring data re-use for subsequent matters.

BIA has proprietary methods to ensure data processed once can be reused multiple times.

We make it easy for our clients to reuse processed data, reviewer coding calls and other attorney work product for new cases.

That keeps the review efficient and ensures privileged documents stay safe. It also allows attorneys to focus on strategy, not processes.

Every File Processed Is Run Through Many Tasks

Every file that moves through the BIA eDiscovery processing pipeline is automatically checked and scanned for issues, text and other information to ensure subsequent eDiscovery phases are effective.

  • Advanced file cataloging & custodian tracking
  • File type authentication & categorization
  • Virus & malware detection & quarantine
  • Archive & container parsing
  • File hashing (digital fingerprinting)
  • De-NIST (known file filtering)
  • Attachment & advanced embedded file extraction
  • Comprehensive metadata extraction
  • Full-text extraction & OCR
  • Comments & other hidden content detection
  • Foreign language detection
  • Advanced & cross-custodian deduplication
  • Full text & metadata indexing
  • Automated error & corruption handling
  • Encryption & password detection
  • Comprehensive reporting

Make Critical Decisions

Gain critical insight on data volumes, costs and scope.

By presenting easy-to-understand intelligence and reporting about the processed data (ESI), legal teams are better prepared to make rapid, more informed decisions regarding overall discovery costs, legal strategy and settlement options.

BIA acts as a conductor to an eDiscovery data processing orchestra of tasks. We ensure all details are covered, providing logs for error-capturing and handling, multiple hash support, derivative metadata capture and analysis, digitally automated chain-of-custody trails, and several other specific and highly technical functions. Everything we do is customized and well-tuned thanks to our more than 15 years of performing eDiscovery data processing (ESI processing).

We ensure that all of the elements of eDiscovery data processing are performed correctly and put through our stringent quality control (QC) protocols. Our clients can be assured the data is sound and can make the right decisions for case strategy and costs.

Compliant eDiscovery Processing

ESI processing tools and methods that withstand legal scrutiny.

Over the years, we have honed and documented our methods and processes, and we can ensure all eDiscovery data processing is compliant with computer forensics standards and practices.

One of the greatest challenges to getting eDiscovery data processing right is to make sure that the process itself does not taint the data and cause potential spoliation claims.

We leverage the best legal technology in the industry to deliver the many phases that follow eDiscovery data processing,  ensuring everything happens smoothly from beginning to end.

Catalog and Index

The eDiscovery software and other tools we use to ensure accurate searching and filtering in subsequent stages by subjecting all data to an advanced set of forensic cataloging tasks, including recording and indexing all metadata and any embedded objects. Using multiple methods of data validation and mature eDiscovery processing technologies, TotalDiscovery allows for a defensible and accurate ESI data reduction strategy.

Search and Filter

The BIA ESI processing system involves layers of communications and processes between several different technologies including:

  • OpenText TotalDiscovery Processing
  • Relativity Processing (with or without Relativity Analytics)
  • MindsEye Processing
  • LAW
  • Nuix
  • Other open-source and proprietary technologies

Throughout it all, BIA leverages powerful and well-accepted indexing technologies tuned specifically for eDiscovery and legal data filtering and searching requirements.

No advanced searching skills are needed to quickly and accurately reduce the size of your processed ESI before delivering the data to attorneys for the legal document review phase of the matter.

Tried and True eDiscovery Processing Methods and Procedures

BIA’s systems and processes identify duplicates using advanced technologies and algorithms — including those developed by BIA over 10 years ago and that are used in several industry-standard systems today, including the eDiscovery software application TotalDiscovery and others.

We have tools for cross‐custodian deduplication, filtering with search terms and phrases, deep analytics and other options. They all help to further cull processed data to manageable levels and easily find relevant files, reducing costs at each step and giving you unprecedented control over your legal document review.

Review set deliveries can be formatted by choosing a custom saved template for transfer and seamless loading too many of the most popular document review and analysis tools and platforms.
