INTRODUCTION

English translation pending.

CORE DEFINITION

Every passage leaves traces holds that any behavior produces evidence, and that however covert it tried to be, some faint mark remains to be followed. It builds evidence awareness in two directions: an investigator should believe the trace exists and hunt for it systematically, and an actor should remember that every move also leaves traces of its own.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Believe the trace exists: start the search from the assumption that marks remain - Reason to the byproduct: work backward from the act to the residue it leaves - Watch your own feet: remember you are leaving a trail while you follow one

Anchor fast decisions

Any action changes the environment or the system state it acted upon, and that change is the evidence: physical material, a digital log, a behavioral signature. Concealment only raises the effort needed to find the mark, because the byproduct of the act exists whether or not anyone looks for it.

Sherlocking

Sherlocking refers to the phenomenon where a platform owner copies the features of a third-party developer's app and integrates them into the platform, thereby rendering the third-party app obsolete. The term originates from Apple's Sherlock search tool, which was introduced in Mac OS 8.5 and later incorporated features similar to those of third-party search utilities like Watson, leading to the coining of the term.

Overfitting

In mathematical modeling, overfitting is the production of an analysis that corresponds too closely or exactly to a particular set of data, and may therefore fail to fit to additional data or predict future observations reliably. An overfitted model is a mathematical model that contains more parameters than can be justified by the data.

Locard's Exchange Principle

In forensic science, Locard's principle holds that the perpetrator of a crime will bring something into the crime scene and leave with something from it, and that both can be used as forensic evidence. Edmond Locard (1877–1966) was a pioneer in forensic science who became known as the Sherlock Holme…
