Last month, we advised you on the coming sea change in the discovery world, thanks to two major tech changes:

Major tech change #1: The 5G network

The advent of the 5G network will force internet of things (IOT) devices to the forefront of discovery. IOT devices combined with 5G technology will make mountains of data about our lives easily accessible and always available.

Major tech change #2: The internet of things

When addressing electronically stored information (ESI) in the course of discovery, it’s not just about emails and Microsoft documents anymore.

We now have “data lakes” that store information from phone applications, iPad files, messenger applications and especially the IOT. With all of our TVs, cars, lightbulbs, appliances and most other devices now being “smart” and recording data, the number of discoverable sources of data is exploding.

The problem is: how do we review all of the data contained in this lake?

Historically, the short answer has been: “kind of patchwork”, depending on the software platforms you have available to you. Traditional databases like Relativity, Summation or CloudNine are great and powerful tools, but the pace of innovation with data sources is seemingly outpacing our traditional web review platform’s ability to present these various sources of data seamlessly.

Their shortcoming in this instance is that they are all relational databases that tie together information (metadata) to a document (native file or PDF/TIFF). With all of the new sources in our data lake, oftentimes these traditional databases cannot display and search all of these sources in the same database.

Many of the newer data sources do not have documents or native files available and are instead “event” based. This means that each time you open your smart refrigerator door, the action is logged as an event but there is no document or file associated with it, simply an entry in a log file.


Typically, the task of reviewing these events and log files alongside more traditional data calls for quite a bit of manual work and software work arounds to make all of the data available for review in one place.

Emerging technology, like ESI Analyst, is bringing the data together.

The legal technology sector is starting to introduce solutions to this problem, and they are powerful. One emerging technology we’re really impressed with, and who we’ve recently partnered with, is ESI Analyst.

ESI Analyst is an eDiscovery tool that helps attorneys tell the entire case story by combining multiple sources of digital evidence, including event-based log entries, in a single platform. ESI Analyst powers timelines, charts, reports, review and production of multiple forms of modern electronic evidence at an affordable price point.

Let’s look at two real-life scenarios that have been historically difficult, but that will soon be commonplace thanks to ESI Analyst’s capabilities.

Scenario 1: Reviewing WhatsApp Data

During custodian interviews, you and your client realize that some of the key custodians have been using alternative communications methods. Specifically, WhatsApp. You need to collect, review and produce all responsive, non-privileged WhatsApp data.

Traditional review databases (CloudNine, Relativity, Summation) are fantastic for the organization and review of common data sources: emails, Microsoft Office documents, file shares and the like. Non-traditional sources of data can be ingested into these databases, but it often requires custom development to make everything work correctly.

WhatsApp is a fully encrypted cross-platform messaging and VoIP service owned by Facebook. It allows users to send text and voice messages, make video and voice calls, and share pictures/videos/files. WhatsApp is accessible from Windows and Mac desktop computers and any mobile device. Given the multitude of documents and data WhatsApp can share, it is a tall task to fully integrate it with most review platforms. What’s more, WhatsApp data is now involved in more cases than not.

ESI Analyst can easily display WhatsApp and other messaging data.

The good news: ESI Analyst is uniquely positioned to accommodate the review and analysis of WhatsApp data, as well as other similar collaborative messaging tools.

The secret to ESI Analyst’s ability to easily display all of this data automatically within their platform is that it treats each message or file as an “item”, and common communications between participants as a “thread”, not as documents. This allows us to collect multiple devices from the same user and programmatically deduplicate data from one device against another. The end result being a collection of unique data from WhatsApp that is non duplicative and inclusive.

ESI Analyst also displays each conversation in a more familiar way where messages, pictures and videos all display in the order that they were sent/received and not separated by type, as happens with traditional methods.

All of these factors make reviewing WhatsApp data extremely powerful. Resulting data can be tagged and exported for further review (and can be integrated into CloudNine or Relativity databases) or can be directly produced out of ESI Analyst.

Scenario 2: Proving Geolocation at a Specific Time

A local car dealer (Car Dealership A) is accused of defamation against his cross-town rival (Car Dealership B). The accusations in the case include:

  • Paying a Philippines-based company to produce fraudulent negative reviews on his competitor’s website
  • The owner of the defendant car dealership being personally accused of leaving fake negative reviews by accessing unwitting customer’s phones

In this case, the data is going to tell the truth if we can acquire it and understand it. We know that there were several dozen online reviews that appear to be fraudulent. Out of those several dozen, most are tied to an IP address in the Philippines. Although the IP addresses made it obvious that they weren’t real customer reviews, it wasn’t enough evidence to prove who purchased the false reviews. A couple of ignored 3rd party subpoenas later, and this case appeared to be dead in the water.

At this point, we decided to look at the other negative reviews on Dealership B’s website and see if we could tie them to an actual customer. There were a handful of reviews that were flagged as possibly suspicious and the case team went to work trying to contact the non-customers who left negative reviews. Luckily enough, we found a person who was willing to help us solve this puzzle. As it turns out, one of the customers who left a bad review at Car Dealership B was an actual customer of Car Dealership A. When she was finishing up her negotiation, she was offered an additional $500 discount if she would leave a positive review for Dealership A. The owner was very specific about what she had to say and told her if she didn’t do it exactly word-for-word as he said, the discount would be rescinded. Instead of losing the $500 discount, the customer simply handed her phone over to him as he offered to simply type it for her. The owner then proceeds to leave a negative review for rival Dealership B from the woman’s cell phone as well as a positive review for his own dealership.

This is great news for the case team but now comes the hard part: how do we prove it? While there are dozens of options to review emails and the like, how do you prove where mobile reviews were posted from (geolocation) and how do we explain this in court using only longitude and latitude numbers? This real-life scenario perhaps plays out in court when cell phone location data is needed. It sometimes takes a full day to instruct the jury as to how cell phone triangulation works and then to show the data and explain, in longitude/latitude numbers, where the subject was located. It is confusing and frustrating but must be done in some cases. Luckily for Car Dealership B, ESI Analyst was now available.

ESI Analyst Screenshot

ESI Analyst can show the mapped location of a device at a specific time on a single screen.

By utilizing the location history of the mobile device and the “item” logging architecture of ESI Analyst, we were able to demonstrate that at the exact moment that the negative review was being posted on Car Dealership B’s website, the phone was physically located at Dealership A. We were able to show, on one single screen, the mapped location of the cell phone at the moment of the review was posted. This proved that the customer’s phone was physically located at Dealership A at the precise time the negative review for Dealership B was posted.

This emerging technology creates a discovery opportunity for attorneys on both sides of a case.

Change is coming in the eDiscovery world, in the form of data lakes, IOT, 5G, and advances in how we can produce and display data.

What type of modern data is/will be available for your cases and how do you use that data to help win more cases? Depending on your practice and your clientele, the answers will vary. The first step is to consider the type of data points that are starting to become available and to find a way to use that data to help prove your case. With the right tools in place, you can leverage these new discovery opportunities and strengthen your cases.
