Reverse image search
A search technique in which an image, rather than text, is submitted to a search engine to find other instances of that same or similar image online. Effective against a stolen real photograph reused under a false identity; ineffective against a wholly synthetic image, which has no original source photo anywhere online to match.
Defined in 2 GAGE programs, which carry 3 distinct definitions of it. The wording above is taught in Senior AI Scam Defense.
How each discipline defines it
The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.
A search technique in which an image, rather than text, is submitted to a search engine to find other instances of that same or similar image online. Effective against a stolen real photograph reused under a false identity; ineffective against a wholly synthetic image, which has no original source photo anywhere online to match.
Searching by an image itself to find where and when it first appeared and its original context; the primary tool for catching real or generated images presented out of context.
A search technique that uses an image itself, rather than typed keywords, as the search input, returning other places on the internet where the same or a visually similar image appears. Described in this topic as a useful optional supplement to, never a substitute for, the primary verified-channel check.

Where it shows up at work
A definition is where Reverse image search starts. The lessons above teach it inside the competencies below, which are what job descriptions ask for and what the GAGE credential records. Every link here is drawn from the same careers map that builds a role's readiness check.

How job descriptions say it
Postings rarely use the textbook word. These are the phrases the careers map reads as asking for the competencies above.
Where the frameworks place it: FTC guidance; FinCEN elder financial exploitation advisory; EU AI Act Article 50; C2PA Content Credentials.
One interview question about it
A caller sounds exactly like a colleague and asks for a transfer. How do you tell a voice clone from a person, and what is the rule?
Asked of candidates for deepfake, voice-clone and scam recognition. Answering it in your own words is exactly how a GAGE topic is passed, and the credential records the pass where an employer can check it.
If you come from another field
Some backgrounds already carry this competency, and the readiness check gives credit for it.
- Elder services, social work, banking front line and fraud teams carries it as a claim to back up: Fraud patterns are familiar; the synthetic versions are new.
