In foreign nations, the researches on the print-scan resistant digital watermarking technology mainly concentrate in the transform domain, which includes DCT domain, DFT domain, DWT domain and other transform domains, while in China the researches chiefly focus on the spatial domain and transform domain. The application fields of the print-scan resistant digital watermarking technology are discussed in three aspects, i.e. the embedding scope of digital watermark, watermarking applications in detection system, and digital watermarking applications in enterprises. At present, the watermarking technology is still not mature. Its researches and applications can be further improved in embedding strength, embedded information capacity, embedded practical applicability and the other directions respectively.
