Embodiment

[0071] A certain provincial archives is an archives with massive archives resources. After the digitization of archives is completed, the originality and integrity detection of archives has become the main problem in the use of digital archives during the use, storage, transmission and utilization of digital archives resources. . Only when the originality guarantee of archival resources and content authentication and tampering detection in the process of transmission and utilization are effectively solved, the utilization of digital archives will have substantive significance. In the process of utilizing digital archives, there are mainly the following problems: during the transmission and utilization of digital archives, content authentication and tampering detection cannot be performed, and originality detection and copyright certification cannot be performed on the transmitted archive content.

[0072] Aiming at the actual problems and specific requirements of the archives,...

Abstract

The invention discloses a digital watermark generation and embedding method based on comprehensive characteristics of digital archival resources. A comprehensive characteristic database of the digital resources is established by analyzing a comprehensive characteristic set of the digital resources and a comprehensive characteristic quantity set, and characteristic quantity is extracted from the digital resources. The extracted characteristic quantity is encrypted and then stored in the characteristic database, a digital watermark is simultaneously generated from the extracted characteristic quantity according to the characteristics of the digital resources by using different algorithms, and the digital watermark embedding algorithm is utilized for embedding the generated digital watermarkinto the digital resources; when primitiveness, integrity, authenticity and uniqueness of the digital resources are identified, the embedded digital watermark can be extracted through the digital watermark extraction algorithm according to the type of the digital resources, and the characteristic quantity of the digital resources in the watermark is further extracted and subject to contrast detection of the comprehensive characteristics with the characteristic quantity of the digital resources or the characteristic quantity in the characteristic database, thereby realizing the primitiveness, integrity and authenticity detection on the digital resources. The method is widely used in archives and units for management of the digital resources.

Description

technical field [0001] The invention relates to a computer image processing method. Specifically, it relates to a digital watermark generation and embedding method based on comprehensive characteristics of digital resources. Background technique [0002] At present, data watermarking technologies mainly include embedding user and producer information into documents as watermarks, semi-fragile digital watermarking algorithms for document images based on DCT transformation, and using meaningful binary images as watermark images. Embed the watermark in the image, encode the Hu invariant moment of the image RICM into the content watermark information and embed it in the original image, digital watermark algorithm based on JPEG 2000 digital image content authentication, digital watermark algorithm solution based on wavelet domain image authentication, Fragile watermark algorithm based on genetic algorithm, fragile watermark authentication technology based on image content, by ge...
