Based On The Design Of The Handwriting Technology Electronic Documents System

Electronic Document System can transfer report, referendum, replying, bulletin and information among departments quickly through computer network on the premise of information security. It can improve the efficiency of disposing document greatly, and save work resource. These days it becomes the studying hotspot in computer field.Designing an Electronic Document System based on handwritten technology is the target of this paper. The system has the traditional Electronic Document System processing flow. Some new technologies such as handwritten remark, electronic stamp and digital watermark were applied to the system. For this target, the System was divided into three subsystems-Document managing subsystem, Document remarking subsystem and Dispatch's documents receiving subsystem.After introducing some difficulties which were studied before the beginning of the design, the paper introduces the realization of each part's functions. First, the paper introduces the realization of handwritten remark, lists several methods that have been usually used at present, and narrates the advantage of our method contrasting with others. Second, the paper introduces the encrypting algorithm for document and the knowledge of digital watermark, in addition, it explains the realization detail of watermark's embedding and distilling algorithm based on stillness color bitmap.The realization method of handwritten remark which is introduced in this paper have characteristic such as practicability, convenience, advancement, etc. The scheme of watermark realization provides a reliable method of information hiding.
