Fig. 1 is the schematic flow sheet based on the safety certifying method of image in a kind of embodiment of the present invention.As shown in Figure 1, the process of this safety certification comprises image acquisition phase and image authentication stage:
Step 101, collection generation first scanned copy is carried out to image, the first file eigenvalue that safety certification calculates this image is carried out to the first scanned copy, and/or, generate the first watermark of this image according to the information in image, the first file eigenvalue and/or the first watermark are kept in archive management system.
This step belongs to image acquisition phase, in this step, collection generation first scanned copy is carried out to the image such as archives and bill, the authentication method good to the first scanned copy predefine or strategy carry out safety certification calculating, draw the first file eigenvalue of this image, such as md5 encryption is carried out to all pixel information of scanned copy, and calculate the first file eigenvalue by digest algorithm; Such as, and/or generate the first watermark by the key feature information in image according to assignment algorithm, the key message be concerned about user is as the date, and signature waits and generates the first watermark with Linux standard criterion (LSB, LinuxStandardsBase) algorithm.Image and the first file eigenvalue and/or the first watermark are bound, the first file eigenvalue of image and binding and/or the first watermark are kept in the database of archive management system.
Step 102, arranges the authentication of user.
In this step, one or more that can arrange user name, password, fingerprint and face feature scanning etc. are as authentication.
In the present embodiment, first carry out step 101, then carry out step 102, other orders are also passable certainly, such as, first carry out steps 102, then carry out steps 101, or carry out step 102 at the sweep phase carrying out step 101, do not limit at this.
Step 103, the authentication according to arranging judges that whether user is legal, if legal, carry out step 104; If illegal, refusal user enters archive management system.
In this step, to needing the user entering archive management system to carry out safety certification, such as, carry out safety certification according to modes such as the user name arranged, password, fingerprint and/or face feature scannings.If safety certification is passed through, then carry out follow-up step; If safety certification is not passed through, then archive management system cannot be entered.
Step 104, carries out collection generation second scanned copy to image, carries out to the second scanned copy the second file eigenvalue that safety certification calculates this image, and/or, the second watermark of this image is generated according to the information in image.
This step belongs to the image authentication stage, in this step, collection generation second scanned copy is carried out to the image such as archives and bill, safety certification calculating is carried out to the second scanned copy authentication method identical with image acquisition phase or strategy, draw the second file eigenvalue of this image, such as md5 encryption is carried out to all pixel information of scanned copy, and calculate the second file eigenvalue by digest algorithm; And/or, the second watermark is generated according to assignment algorithm by the key feature information in the image identical with image acquisition phase, the key message be such as concerned about user is as the date, and signature waits and generates the second watermark with Linux standard criterion (LSB, LinuxStandardsBase) algorithm.
Step 105, judge the second file eigenvalue and/or the second watermark and the first file eigenvalue that archive management system is preserved and/or the first watermark whether identical, if identical, allow user to process the image in archive management system; If not identical, refusal user processes the image in archive management system.
In this step, in the first file eigenvalue that archive management system is inquired about and image is corresponding and/or the first watermark, first file eigenvalue and the second file eigenvalue are compared, and/or first watermark and the second watermark compare, if identical, user is allowed to process the image in archive management system; If not identical, refusal user processes the image in archive management system.
Compared to the prior art, the present invention is carrying out on the basis of safety certification to user, also by carrying out safety certification to the image in archive management system, improve the safety and reliability of file administration.
