Compresi i dati di esempio di una cattura schermo OSX da un desktop OSX analizzati da tre diversi strumenti di seguito. Non sembra contenere l'indirizzo IP ma contiene la marca e il modello del tuo computer e in alcuni casi alcune informazioni sulla directory (ho anche notato che se usi uno schermo esterno conterrà informazioni diverse rispetto a se lo screenshot è preso da il tuo display principale).
Aggiornamento: ho appena testato un'acquisizione di uno schermo iPhone (iOS 9.3.2 ma con servizi di localizzazione disattivati e praticamente le impostazioni di privacy massime) e avevo quasi identici tipi di informazioni per quel dispositivo come le informazioni di seguito.
Nota: i computer con diversi sistemi operativi e software possono includere informazioni aggiuntive non mostrate di seguito. Inoltre, diversi strumenti potrebbero essere migliori o peggiori nell'interpretazione dei dati EXIF e questo potrebbe portare ad alcune informazioni che non sono elencate qui.
La visualizzazione delle schermate catturate con un editor esadecimale sembrava indicare che la maggior parte dei dati EXIF è stata trovata da questi strumenti. Anche in questo caso, potrebbe facilmente cambiare con qualsiasi dato aggiornamento software.
