Anti-counterfeiting seal gets national patent. After retirement, 65-year-old Hong Guomin became obsessed with playing on the computer. He found a "way" on the computer; from self-studying drawing software to designing his own private seal patterns, it wasn't long before he made a name for himself: the "digitally encrypted anti-counterfeiting seal" he invented was reviewed and approved by the National Intellectual Property Administration and granted a patent certificate on February 1, this year. On February 1, 2012, Hong Guomin received the "Patent Certificate for Design" approved and issued by the National Intellectual Property Administration. His encryption anti-counterfeiting seal officially obtained national patent rights. Patent number: ZL 201130295983.3. He said, "The encrypted anti-counterfeiting seal I invented is to use a specific encryption method to add the password thought of by the seal user to the edge of the seal's frame. Every time the seal is used, the encrypted imprint will be different each time, making it impossible to forge." Hong Guomin believes that anti-counterfeiting is not about anti-counterfeiting the seal, but about anti-counterfeiting the imprint, because even the most complex seals can still be imitated. Using a digitally encrypted anti-counterfeiting seal solves this key problem.
