Abstract
A copy method used in a copy system or a copy apparatus connected to a cloud server includes steps of: scanning a document to obtain old image data containing an old information block; generating new image data containing a new information block according to the old image data; printing the new image data on a medium; and comparing different generations of original image data, one of which is contained in the old image data, in the cloud server to judge whether improper modifications are present on the original image data or not, and notifying an information office to perform an inspection when the improper modifications are present.
Claims10
A copy method used in a copy system or a copy apparatus connected to a cloud server, the copy method comprising steps of:
- scanning a document to obtain old image data containing an old information block;
- generating new image data containing a new information block according to the old image data;
- and
- comparing different generations of original image data, one of which is contained in the old image data, in the cloud server to judge whether modifications are present on the original image data or not, and notifying an information office when the modifications are present, wherein a first reference point of the old information block is offset from a second reference point of the new information block by a displacement so that copy generation-count information of the new image data is judged according to a position of the second reference point.
A copy method used in a copy system or a copy apparatus connected to a cloud server, the copy method comprising steps of:
- scanning a document to obtain old image data containing an old information block;
- generating new image data containing a new information block according to the old image data;
- and
- comparing different generations of original image data, one of which is contained in the old image data, in the cloud server to judge whether modifications are present on the original image data or not, and notifying an information office when the modifications are present % wherein the new information block containing new copy generation-count information is generated according to old copy generation-count information contained in the old information block of the old image data, the old information block is subtracted from the old image data to obtain a subtracted result and the new information block is added to the subtracted result to generate the new image data.
