Woran erkennt man manipulierte Fotos? (Photoshop / etc.)

MacEnroe · 28.08.2020

Genau. Probiers aus. Regler extrem verstellen und schauen, was passiert.

- gibt es exif Daten zum Bild, oder sind auch diese schon gelöscht oder manipuliert (Plausibilität)
- liegt das Bild in einer ausreichenden Qualität vor damit man überhaupt eine Chance hat eine Manipulation zu erkennen?

Der TE hat ja erwähnt dass das Bild via WhatsApp gekommen ist. Da kannst du nichts mehr herauslesen und die Qualität ist mieser als mies.

Lor-Olli · 28.08.2020

@ims
Ein wenig spezifischer ist es schon… Bei den von Dir verlinkten Reglern wird immer das ganze Bild manipuliert wenn man nicht vorher Masken festgelegt hat.
Diese Regler kann man trotzdem verwenden und mal ein wenig herumspielen, bei manipulierten Bildern, eingefügten oder getauschten Inhalten zeigen sich dann (wenn die Täuschung nicht sehr sorgfältig gemacht wird) plötzliche andere Veränderungen bei Farben oder Kontrasten etc. als beim Rest des unmanipulierten Bildes

Aber am Duplikat!
Vorschau in aktuellen macOS schreibt ja in die geöffnete Datei auch ohne selbst »Speichern« gewählt zu haben.

Lor-Olli · 28.08.2020

@hutzi20,
ja, wäre schon nützlich wenn der TE zumindest etwas zur Auflösung, Bildgröße und evtl. Kompression schreiben würde. (WhatsApp Bild sagt mir jetzt nichts, ich nutze gar kein smartphone

)

ims · 28.08.2020

Da kann man nicht wirklich einen Unterschied merken.

Aber wie gesagt, die Bilder (sind zwei) sind per WhatsApp verschickt und haben folgende Daten:

182 KB (1600 × 1200)
Farbraum: RGB
Farbprofil: sRGB IEC61966-2.1
Alpha-Kanal: nein
Auflösung: 96 dpi
Bittiefe 24
Attribute: A

384 KB (1200 × 1600)

Ich würde mich am Haar bzw. der Frisur orientieren und an der direkten Umgebung davon. Sind die Kanten zu hart / weich. Sind plötzlich Strähnen oder einzelne Haare abgeschnitten. Sind Teilbereiche der Frisur anders eingefärbt weil ein anderer Hintergrund vorhanden. Oder irgendwelche Lücken / Blitzer vergessen worden. Sind Teilbereiche der Frisur ungewöhnlich glatt gestrichen oder vereinfacht worden. Oder ungewöhnlich scharf gegenüber den anderen darauf befindlichen Frisuren. Haare und generell Frisuren sind mit das schwiergste was es zu retuschieren gibt. Das ist zeitaufwendig und sprichwörtlich zum Haare raufen.

Das ist doch schon eine anständige Größe, um etwas erkennen zu können.

Roman78 · 29.08.2020

Es gibt spezielle forensische Programme um solche Modifikationen fest zu stellen.

ims · 29.08.2020

Ich habe nun zwei Programme gefunden und Suche gerade ob es die noch gibt:

JPEGsnoop
Picture Manipulation Inspector -> https://de.wikipedia.org/wiki/Picture_Manipulation_Inspector

Wenn ich die beiden Bilder mit JPEGsnoop teste kommt folgendes Ergebnis:

ASSESSMENT: Class 1 - Image is processed/edited

wenn ich ein unbearbeites Foto von mir nehme kommt folgendes:

ASSESSMENT: Class 4 - Uncertain if processed or original
While the EXIF fields indicate original, no compression signatures
in the current database were found matching this make/model

Ich würde gerne das komplette Ergebnis der beiden Bilder hier posten, doch es ist zu lang. Weil verstehe es nicht wirklich, vielleicht kann wer von Euch damit was anfangen.

Tja, da stellt sich nun die Frage – in welchem Umfang? Nur Helligkeit und Kontrast oder mehr? Vielleicht wurde es ja mit einem Handy aufgenommen und irgendein Effektfilter war aktiviert?
Wir werden es nie erfahren, wenn wir es nicht sehen können.
Ich rate mal wild ins Blaue: Jemand will den Eindruck erzeugen, Person A betrügt Person B und hat in ein Foto von Person A Person C hineinretouchiert.

Sunlion · 29.08.2020

Doppelgemoppelt.

Ich würde behaupten, dass schon alleine die Verkleinerung/Komprimierung durch WhatsApp hier reinfallen würde …

An dem ganzen output des Programms kann man nur erkennen, dass das Bild bearbeitet wurde. Ob die Bearbeitung eine Manipulation war ist nicht ersichtlich (und so wie ich das sehe, auch gar nicht Zweck des Programms)

ims · 29.08.2020

Was mir auffällt ist, dass bei dem Ergebnis von Bild 2 am Ende was von Photoshop (etc.) steht und bei dem Ergebnis von Bild 1 nicht.

Woran erkennt man manipulierte Fotos? (Photoshop / etc.)
