The existing image authentication methods are watermarking, cryptography and robust image hashing method. Digital watermarking is the science and art of embedding copyright information called watermarks in the files. Cryptography includes encryption and decryption to transfer documents or images.
Product authentication involves verifying the authenticity and quality of products being sold in the secondary market, such as pre-owned or vintage fashion items. The fashion industry, particularly high-end luxury brands, is susceptible to counterfeiting, with replicas flooding the market.
Text Based Image Authentication: (TIA) Sometimes or even most of the times people recollect the names of someone or something on seeing his image. Based on this ability, a technique is developed where the user types the password on seeing the images. This technique uses text as the password to provide authenticity.
