Embodiment 1
[0026] Without loss of generality, as figure 1 As shown, the present invention provides a method for tracing information sources of copied documents, including:
[0027] S1000: Obtain first information related to the original file;
[0028] S2000: Obtain second information related to the copy operation; and
[0029] S3000: Generate a traceability mark at least according to the first information and the second information, and generate the traceability mark on the copied document.
[0030] Preferably, the first information includes: graphic information in the original file. The copier obtains the graphic information of the copied original by scanning, and the acquired graphic information may carry a recognizable barcode or no barcode.
[0031] Preferably, the first information further includes: barcode information. When the photocopier obtains the barcode information in the image and text information of the copied original through scanning, the copier will recognize, read a...
Embodiment 2
[0036] Such as figure 2 As shown, in this embodiment, the specific implementation steps of an embodiment in which the method in the embodiment is applied to copier management are as follows:
[0037] S100: Configuring barcode features; the barcode features include: barcode size and output form; the barcode output form includes: outputting only the barcode or simultaneously outputting supplementary text information below the barcode while outputting barcode information. The configured barcode feature provides technical support related to the format of the basic information for obtaining the first information related to the original file.
[0038] S200: Send the identity information identified by the embedded device to the copier, and set operation information on the copier; the operation information is second information related to the copy operation; the embedded device is an identity recognition function Hardware equipment, for example: an identity recognition device with a...
Embodiment 3
[0054] On the basis of Embodiment 2, the barcode displayed in the output form includes: confidentiality level, unit name, department name, copy number, copy page number, copy operator's ID card number and / or facial feature identification code At least one of the information, and the job ID and traceability information ID; the content of the text information displayed in the output form includes: confidentiality level, unit name, department name, user name, start time, copying equipment model, number of copies and copying One, several, or all of the page numbers.
[0055] Preferably, the output form of the traceability mark is divided into only containing barcodes and containing text information while containing barcodes. The traceability mark includes the identification information of the copied original document and the identification information of the copy.
[0056] Preferably, the identity information includes: the copy operator's ID card number and / or facial feature iden...
