目的 研究当前数字化防伪技术的原理及实际应用。方法 在介绍防伪验证理论模型和消费者查询模型， 以及数字防伪原理和典型数字防伪技术的基础上， 对二维码和RFID（射频识别）防伪技术的组合应用进行了探讨。 结果 二维码和RFID防伪技术均符合产品防伪验证理论模型， 且RFID防伪技术安全等级高于二维码防伪技术。 结论 数字化防伪技术越来越成熟， 必将成为防伪技术的主要发展方向。

This article studied the principle and practical application of digital anti-counterfeiting technology. Digital anti-counterfeiting verification theoretical model and consumer query model, as well as the digital anti-counterfeiting principle and typical digital anti-counterfeiting technology were introduced, based on which, the combined application of 2-D barcode and RFID anti-counterfeiting technology was explored. Both 2-D barcode and RFID anti-counterfeiting technology were in accordance with the product anti-counterfeiting verification theoretical model, and the RFID anti-counterfeiting technique had a higher level of safety than 2-D barcode. With the development of digital anti-counterfeiting technology, digital anti-counterfeiting must be one of the major trends of future anti-counterfeiting technology.
