Each year the consumer market turns up more and more counterfeit items. Differentiating between verified original products and counterfeits is becoming increasingly difficult. However, the fast development and wide accessibility of modern technology both pose the question whether their utilization may ensure the authenticity of products, all the while increasing the capability of detecting and preventing sales of counterfeits. We have researched new approaches of protecting the authenticity of products, and new mechanisms which make falsification of products more difficult. We have devised a prototype of a system which is based on the supply chain and uses Radio Frequency Identification (RFID) to label products. Encryption algorithms (DES, AES, RSA) have been utilized to prevent product-tag copying. We have defined three models, all with different protection levels. Additionally, we have developed a mobile application which enables the consumer to review a product’s authenticity using its Near Field Communication (NFC) tag, should the product in question have one, with their mobile phone.
