Abstract
The invention discloses a method and a system for managing scanned images of securities. The method for managing the scanned images of the securities includes steps of adding invisible digital watermarks on the scanned images of the securities; extracting effective identification information of the scanned images of the securities; and generating a storage file name of the scanned images to store the scanned images of the securities according to the effective identification information of the extracted scanned images. Safety of the scanned images when printed or copied is improved by adding the invisible digital watermarks on the scanned images of the securities. Enquiry and retrieve efficiencies are greatly improved by extracting the effective identification information of the scanned images of the securities to generate the file name to realize storage and management for the scanned images. Further, shaded print or copy of the securities is prevented by the aids of the visible digital water marks which are added before the scanned images are printed and the invisible digital water watermarks, so that safety in utilization of the scanned images is improved.

Embodiment
Be described further below in conjunction with the accompanying drawing specific embodiments of the invention:
Before the specific embodiment of the invention is described, introduce digital watermarking down earlier.Digital watermarking (Digital Watermarking) is the audio visual effect that does not influence former data toward multi-medium data (like image, sound, vision signal etc.) middle interpolation some numerical information (watermark); And these numerical informations can be partly or entirely recovered from blended data, to reach effect such as copyright protection.The embedding carrier of watermark here can be image, sound, vision signal, can also be text formatting, the scan image of the object securities of digital watermarking of the present invention, and watermark content is a view data.
With reference to Fig. 1, a kind of securities scan image management method may further comprise the steps:
Scan image to securities adds stealthy digital watermarking; The algorithm that adds stealthy watermark is a lot; The present invention is preferably based on the digital watermarking of LSB algorithm and adds algorithm; LSB (Least Significant Bits) algorithm is embedded into the least significant bit (LSB) of carrier image pixel value with watermark content, also claims least significantly position, and it is minimum to the quality influence of carrier image to change this position;
Extract effective identifying information of the scan image of securities; Said effective identifying information is the identification data of this securities uniqueness of sign; With the I.D. is example; Adopt the ID card No. in the character recognition technology identification I.D. scan image, with the effective identifying information of ID card No. as scan image;
Generate the storage file name of scan image according to effective identifying information of the scan image that extracts,, for example, come the storage administration scan image as the filename of I.D. scan image with ID card No. with the scan image of storage securities.
It will be understood by those skilled in the art that the identification data of said effective identifying information as this securities uniqueness of sign, for check, effectively identifying information can be cheque number; For bank card, effectively identifying information can be for this bank card number etc.Like this, the scan document image of management securities that can be rapidly and efficiently is convenient to user's retrieval and inquisition.
Further as preferred embodiment, the watermark content of said stealthy digital watermarking comprises the purposes and the date of securities scan image, and the watermark content synoptic diagram is as shown in Figure 5.Certainly, the watermark content that it will be understood by those skilled in the art that stealthy digital watermarking can also comprise bar code or other expression property information.Stealthy digital watermarking is positioned at the effective coverage of the scan image of securities, has prevented the covering property printing of securities scan images like this.The scan image that adds after the stealthy digital watermarking is as shown in Figure 4, to the not influence of visual effect of scan image, but when printing this scan image, then can show the watermark content of stealthy digital watermarking, and this watermark content can be paved with whole scan image.
Fig. 2 is the flow chart of steps of securities scan image management method embodiment two of the present invention; Present embodiment two increases a step of adding visible digital watermark on the basis of previous embodiment; Be specially: before the operation of printing said scan image, scan image is added visible digital watermark.
The process of adding visible digital watermark is following:
Pixel on the scan image of setting source is Source (RGB), and the pixel on the watermarking images is Mark (RGB), and the pixel on the image of synthetic back is Dest (RGB), uses following formula:
R(Dest)=R(Source)*alpha+R(Mark)*(1-alpha)
G(Dest)=G(Source)*alpha+G(Mark)*(1-alpha)
B(Dest)=B(Source)*alpha+B(Mark)*(1-alpha)
R in the following formula (Source), G (Source) and B (Source) are divided into red on the scan image of source, green, blue pixels value; R (Mark), G (Mark) and B (Mark) are respectively red on the watermarking images, green, blue pixels value; R (Dest), G (Dest) and B (Dest) are respectively redness, green, the blue pixels values on the image of synthetic back; Alpha is a coefficient of transparency, and value is 0 ~ 1.Fig. 3 is the effect synoptic diagram that securities of the present invention (is example with the I.D.) scan image adds visible digital watermark.The watermark content of visible digital watermark comprises the purposes and the date of securities scan image.Certainly, the watermark content that it will be understood by those skilled in the art that visible digital watermark can also comprise bar code or other expression property information.Visible digital watermark is positioned at the effective coverage of the scan image of securities, has prevented the covering property printing of securities scan images like this, has avoided scan image to be diverted to other purpose.
With reference to Fig. 6, a kind of securities scan image management system comprises:
Stealthy digital watermarking adding device 10 is used for the scan image of securities is added stealthy digital watermarking, and the present invention is preferably based on the digital watermarking of LSB algorithm and adds algorithm;
Effective identifying information extraction unit 20 is used to extract effective identifying information of the scan image of securities, and said effective identifying information is the identification data of this securities uniqueness of sign.With the I.D. is example, adopts the ID card No. in the character recognition technology identification I.D. scan image, with the effective identifying information of ID card No. as scan image;
Filename generates and storage unit 30, is used for generating according to effective identifying information of the scan image that extracts the storage file name of scan image, with the scan image of storage securities.
Further as preferred embodiment, this system also comprises:
Visible digital watermark adding device 40 is used for before the operation of printing said scan image, scan image being added visible digital watermark.
Preferably, said stealthy digital watermarking and visible digital watermark are positioned at the effective coverage of the scan image of securities, and the watermark content of stealthy digital watermarking and visible digital watermark comprises the purposes and the date of securities scan image.Watermark content can also comprise the expression property information of other expression securities scan image purposes.Scan image is when being printed like this; Watermark content is added on the scanning document of printing; When scanning document is scanned by extraordinary scanner once more; Can also detect the digital watermarking that comprises in the scan image through the digital watermarking detecting device,, protect scan image not diverted to other purpose so that scan image is added digital watermark processing.
More than be that preferable enforcement of the present invention is specified; But the invention is not limited to said embodiment; Those of ordinary skill in the art can also make all equivalent variations or replacement under the prerequisite of spirit of the present invention, distortion that these are equal to or replacement all are included in the application's claim institute restricted portion.
