DCT-phase statistics for forged IMEI numbers and air ticket detection

作者：

Highlights：

• A new phase technique for detecting forgeries in IMEI and air tickets.

• It derives phase spectrum using DCT to find suspicious regions.

• We compute phase statistics to study the effect introduced by forgery.
