ABSTRACT:
The invention relates to a product protection system whereby a product piece is provided with a product-specific identification sequence (K) which is converted into a coded check sequence (C), by means of an encoding method (F1) using a secret encoding sequence (B). A product control sequence is applied to or on the product piece which comprises the coded check sequence (C), or a sequence derived therefrom. In order to check the authenticity of the product piece, the product control sequence is recorded by a control requester and transmitted by internet to a product protection server structure. A decoded check sequence is derived therein from the product control sequence by means of a decoding method using a decoding sequence. The authenticity of the decoded check sequence, or a sequence derived therefrom is checked and the result of the authenticity check transmitted by internet to the control requester.
