The Evolving Role of Emojis in eDiscovery

We are all familiar with emojis. They are present in emails, text messages, social media, webpages, and virtually every online modality. According to, over one in five tweets now includes an emoji (21.54%) and five billion emojis are sent daily on Facebook Messenger. The sheer number, variations, and sources of emojis is overwhelming. There are several key questions we must consider from an investigative point of view:

1) Do emojis provide any probative value during eDiscovery?

2) Can we translate these quirky images into meaningful text equivalents?

3) Can they be used to communicate covert information in plain sight?

4) Can we determine hostile, threatening, hateful, or discriminatory meaning containing evidentiary value from emojis?

5) Is it possible to track, correlate, connect suspects or accomplices through their use of emojis?

During this session and demonstration, we will dive deeper into each of these areas, discuss and demonstrate tools and technologies that can unlock the meaning, intent, and potential digital evidence to enhance eDiscovery, forensic and incident response. We will also review some noteworthy legal cases affecting the industry.

Please register on Eventbrite.
