The principle and application of taatoo's invisible watermarking technology
taatoo adopts AI-based invisible digital watermarking technology, which embeds information by modifying specific frequency domain features of image pixel data. The advancement of this technology is reflected in three aspects: first, the watermark information is dispersed and embedded into multiple frequency bands of the image, making it undetectable to the human eye (PSNR value > 45dB); second, a convolutional neural network algorithm is used to optimize the embedding location, ensuring that after common operations such as JPEG compression (quality reduced to 30%), cropping (retaining the original image's 50% region), and rotation (±15°) It can still maintain an extraction accuracy of more than 90%; finally, it supports a multi-layer coding system, which can either store basic copyright information (e.g. "©2025 Zhang San") or contain 64-bit encrypted identifiers.
Typical application scenarios include: embedding customer number before uploading works to the gallery by photographers, hiding contact email address when designers publish works in social media, marking recipient ID when enterprises distribute product photos to partners, etc. After testing, the success rate of watermark extraction reaches 87.6% after 300DPI professional photography works are processed, even after 5 times of dumping and compression.
