forensik foto

sebelum saya mulai percobaan dengan foto yang saya miliki saya akan menerangkan beberapa hal tentang software yang saya pergunakan ini  :study:  maaf sekali lagi yuah jika artikel ini membosankan maklum saya hanya seorang pemula yang masih lom tau apa2  :|  okelah kita lansung ke TKP.

pada percobaan kali ini saya menggunakan software JPEGsnoop
Langkah-langkah untuk Proses file :

file JPEG dengan File-> Open ...
Simpan output dengan File-> Simpan Log ... jika diinginkan

Sebagai alternatif, Anda dapat drag-and-drop file JPEG ke ikon JPEGsnoop atau jendela utama dan laporan secara otomatis Membuka file JPEG secara otomatis akan memulai proses decoding dan generasi dari file log.
Ada beberapa pilihan dapat mengaktifkan decoding file JPEG . Jika opsi Auto ulang di jendela Konfigurasi dinonaktifkan, maka setiap perubahan pada Pilihan di bawah ini tidak akan tercermin dalam log sampai berupa file baru dibuka, atau Anda secara manual File-> ulang.
•Hide unknown EXIF tags - Opsi ini akan menonaktifkan decoding tag EXIF yang saat ini tidak dikenal di's database JPEGsnoop
•DHT Expand  - - Perluas yang JFIF Huffman tabel kode ke daftar aktual dari variabel-panjang string biner yang dicari selama proses decoding
•Scan Segment - Decode Image Pilihan ini ternyata di decoding nyata dari segmen data Scan.Dengan demikian, beberapa pemeriksaan dilakukan untuk memastikan bahwa semua kode panjang variabel adalah valid dan bahwa tidak ada korupsi data.
•Scan Segment - Histogram RGB Jika Decode Image diaktifkan, pilihan RGB Histogram akan menampilkan histogram untuk komponen RGB, selain pelaporan setiap YCC / RGB kliping.
•Scan Segment - Histogram Y - Jika Decode Gambar dan RGB Histogram pilihan diaktifkan, pilihan Y Histogram akan menampilkan histogram menggambarkan pencahayaan (Y) DC komponen gambar.  
•Scan Segment - Full IDCT - Bila pilihan ini diaktifkan, proses scan decode tidak seorang IDCT penuh (Inverse Discrete Cosine Transform) untuk menghasilkan tampilan gambar resolusi tinggi.
•Scan Segment - No IDCT - Bila pilihan ini diaktifkan, proses scan decode tidak melakukan IDCT, dan dapat menghasilkan resolusi gambar tampilan-rendah
•Scan Segment - Scan Dump - Mengaktifkan opsi ini dumps keluar 640 byte pertama dari scan data (dalam mulai dari Scan (SOS) segmen) dalam heksadesimal, setelah memasukkan byte telah ditangani
•Scan Segment - Detailed Decode... - Gunakan opsi ini untuk membuang keluar info rinci tentang VLC Huffman (variabel-panjang kode) yang membentuk bitstream Scan
•Maker Notes - Decode Maker Catatan bagian (-spesifik data produsen) jika itu adalah membuat didukung oleh JPEGsnoop.
•Configuration - Membuka sebuah jendela di mana Anda dapat mengatur beberapa opsi tambahan.

demikian dulu penjelasan tentang software yang saya gunakan kali ini jika ingin lebih jelasnya bisa langsung ke situs resmi JPEGsnoop nya. ok kita mulai percobaannya

pertama-tama saya mempersiapkan 2 buah foto, foto pertama asli dan belum terkena editan dan foto yang ke 2 adalh foto yang sama tetapi telah saya edit sedikit, kemudian jalankan software JPEGsnoop kemudian buka foto percobaan satu maka akan langsung tampil hasilnya , begitu juga foto yang ke 2:

  Based on the analysis of compression characteristics and EXIF metadata:

  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

  Appears to be new signature for known camera.
  If the camera/software doesn't appear in list above,
  PLEASE ADD TO DATABASE with [Tools->Add Camera to DB]
