Charpter 1  Product Background

Current information systems primarily employ security measures such as physical isolation, access control, data encryption, and behavioral auditing to address electronic data security during storage and transmission. However, with the advancement of informatization, an increasing number of official documents and sensitive files are circulated internally and externally after obtaining printing permissions, often through physical paper printing. This has led to frequent incidents of leaks through printed documents being photographed, making printed materials a critical security control vulnerability. The threat of leaks caused by such methods has become increasingly severe, turning printed documents into a high-risk area for data loss and disclosure. Effective control measures are urgently needed to address this issue.

To address these challenges, the newly launched document printing leak traceability and forensics system embeds cross-media invisible watermarks in printed documents, enabling secure control over photo leaks during printing and copying. This system not only identifies the source of leaks but also creates a strong deterrent effect, reducing the occurrence of document photo leaks and effectively lowering the risk of unintentional leaks. The product's application value is particularly outstanding.

Charpter 2  Product Overview

The Document Print Leakage Traceability and Forensics System is a BS/CS hybrid software solution comprising two core modules: a print traceability client and a forensic management backend. This comprehensive solution delivers end-to-end capabilities for document watermarking, leakage tracing, and forensic analysis. When users' devices are compromised through unauthorized document capture, the system employs advanced cross-media invisible watermarking technology to pinpoint the exact source of data breaches with pinpoint accuracy.

Charpter 3  major function

1)Invisible Watermark: Embeds undetectable watermark information in printed documents for leak prevention and traceability. The watermark preserves original font settings (size, spacing, punctuation) and supports standard official fonts including Song, Kai, Kai GB2312, FangSong, Founder FangSong, and FangSong GB2312. It applies to text sizes ranging from 10.5 to 22 (equivalent to 12-16 points), ensuring seamless readability without compromising document functionality.

2)Watermark: Add a visible watermark to printed documents for security.

3)The client has the ability of auto-start, anti-uninstall, anti-delete, anti-termination.

Charpter 3  core value

1)To reduce the occurrence of regulatory breaches, invisible watermarks serve as a deterrent, lowering the risk of paper documents being leaked through photography.

2)Quickly and accurately identify the source of leaks, reducing the cost of tracing and shortening the investigation time after leaks occur from printed documents.

Charpter 4 product superiority

1)The visual effect is excellent, with the invisible watermark minimizing its impact on the visual presentation.

2)The traceability information is precise, enabling detailed information such as device IP, MAC, name, employee ID, and timestamp to be traced through the leaked sample.

3)With robust performance and cutting-edge core algorithms, it maintains high traceability success rates even in challenging scenarios like image compression, cropping, moire pattern detection, and partial document capture.

4)It has strong anti-jamming ability, the watermark information is invisible, and it can effectively avoid directional smearing and erasing.
