Impact of Episodic Memory on Digital Identity

Impact of Episodic Memory on Digital IdentityDigital Trust

The secure digital identity can be achieved only by the joint work of citizens and systems. Episodic image memory plays a big role for the citizens to make it practicable in multiple aspects; it actually enables us to

 come up with Expanded Password System as a legitimate successor to text passwords, “Digital Identity for Global Citizens” (90-second video)

 convert a set of unforgettable images to a high-entropy complex password, "Image-to-Code Conversion by Expanded Password System"

 regenerate the seed of symmetric and asymmetric cryptographic keys on-the-fly, "Account Recovery with Expanded Password System”

 thwart nasty phishing attacks effectively, “Detection of Phishing by Episodic Image Memory" (new)

 mitigate onerous insiders’ jobs and other persistent attacks, "Advanced Persistent Threats in Digital Identity"

 and design a new breed of Brain-to-Machine Interface. “Password & BCI/BMI (Brain-Computer/Machine-Interface)”

A typical definition of Episodic Memory is “the ability to recall and mentally reexperience specific episodes from one's personal past and is contrasted with semantic memory that includes memory for generic, context-free knowledge.” https://www.sciencedirect.com/topics/neuroscience/episodic-memory

Episodic Memory

 While we are advocating a broad use of our episodic memory as the secret credentials for secure digital identity, some people are spreading badly misguided and misguiding perceptions that better security will be achieved by removing the secret credentials from digital identity. Below are our observations on these fallacies.
