Digital paper: anti-counterfeiting features

it is reported that paper anti-counterfeiting has become a sharp weapon in cracking down on counterfeits and the fastest used product in packaging raw and auxiliary materials

internationally, digital paper is also called dpaper or EPA per. In terms of description, it is an electronic book, magazine, newspaper, etc. that can be displayed and read on the computer screen and related equipment. The digital paper industry should have certain security; Including tamper proof and indivisible, which is also an important feature of traditional paper

different from traditional paper, digital paper has its own characteristics, including that it can be used on various platforms, that the original data information (such as title, author, publishing house, etc.) is difficult for traditional paper, and that it has small data size, animation and hyperlink capabilities. At present, adobepdf is the representative of digital paper in the world

from an international perspective, there are two "events" in digital paper: first, Adobe launched the cross platform layout recording format PDF in 1993, which is considered to be the sprout of digital paper technology in the world; The second is that digital paper technology is widely used. After 1999, Adobe launched pdfmerchant, which makes it possible to produce and send e-books in a large scale, safely and efficiently

there are different understandings of "digital paper" at present, and people in the industry also have different understandings

The higher the content of

some experts believe that the birth background of digital paper is the electronization or digitalization of the publishing industry. Since the 1980s, the global publishing industry, including the domestic publishing industry, has gradually realized electronization and digitalization, producing a large number of electronic documents of books, newspapers and magazines, plus the electronic documents of internal office work, which is the embryonic form of digital paper

some experts believe that digital paper is a very broad concept, and there are many manifestations of the combination of digital technology and paper technology. In addition to Adobe's PDF and scholar's SEP technology, various electronic paper and electronic screens are also digital paper in a certain sense

the classification of digital paper should include virtual paper, electronic screen, electronic paper and physical paper. Among them, virtual paper, such as Adobe's PDF and scholar's Sep; Electronic screen, including various display screens with writing and reading functions; Electronic paper is divided into display electronic paper (e-ink, Philips and eBook of Sony in the United States) and specific new materials as follows: printing electronic paper (Ricoh in Japan on behalf of the company) and optical electronic paper (Fuji Xerox on behalf of the company); Physical paper is a material paper with digital characteristics. At present, Microsoft is No. 5. It is engaged in research in this field before experimental operation

digital paper technology can bridge the digital divide - the technology that advocates the integration of digital technology with traditional paper is called digital paper technology

the so-called digital paper technology "different people have different opinions", that is, a technology platform built with digital technology that conforms to the characteristics of traditional paper, so that the original paper-based use habits, systems, regulations, working methods, etc. can smoothly transition to digital form, providing key technical support for promoting information

characteristics of digital paper

digital paper has three main characteristics:

first, it should have strong enough page description ability to completely and accurately represent the information carried by all paper media, and the page should be consistent. After moving from place a to place B, the page will not change

second, it cannot be tampered with. The existing content cannot be tampered with by any operation

third, indivisibility. The official seal in the document cannot be removed and reused elsewhere

in addition, digital paper has the characteristics of small space, easy retrieval, unlimited distance transmission, undistorted replication, almost zero cost of storage, replication and transmission, and almost zero processing time

at the same time, give full play to the advantages of digital technology, which can automatically follow the existing working habits. Just like reading a book, readers can get used to it; It can automatically follow the existing systems and regulations without much change; It can be connected with the links without digital transformation, so that the information construction can be implemented step by step; Any one of the multiple links can be transformed. Digital and non digital can be used together to achieve comprehensive, harmonious and sustainable development, which can minimize the resistance of information construction

digital paper has a wide range of applications and can be used to digitize all information based on paper. Such as digital management of books and newspapers, digital management of archives, image storage management, electronic official documents, application materials, approval and circulation, digital contracts, personal publishing, electronic forms, security documents, other electronic bills, etc

common product form

as a core JB technology, the internal performance of digital paper technology cannot be demonstrated. Here are some common product forms generated by core technologies

virtual printing technology: for example, a doc file can be printed and output to traditional paper. Through virtual printing technology, it can also be output to digital paper, which can be displayed and read on various digital terminals

typesetting file conversion technology: books, newspapers and periodicals in traditional paper media are printed after typesetting. Through typesetting file conversion technology, various typesetting files can be directly converted into digital paper. It can be displayed and read on various digital terminals

paper media content digitization technology: the holographic digital information produced by holographic digitization technology can completely retain all the information of the original paper media, including all text information and all layout information. At the same time, it supports multiple retrieval methods such as full-text retrieval, and the manual workload required in the production process is also small

digital paper making technology: compared with traditional paper, digital paper can have many advantages brought by information technology, which can make people use it more conveniently. Through the digital paper production technology, directory navigation, full-text search index, and setting various permissions (password, printing restrictions, and text picking restrictions) can be added

the "smart"

digital paper technology of intelligent documents is the core technology of IT industry equivalent to database. Based on this technology platform, the scholar company has developed application systems in such fields as document transmission, document sharing management, digital library, electronic forms and so on. Among them, the development and application of intelligent document (IDoc) technology platform plays an exemplary role. Smart documents have the following characteristics:

high fidelity of paper: smart documents maintain absolute high fidelity effect with printed paper documents in terms of appearance, layout and content

dynamic intelligent documents can directly interact with other content, data, applications and even documents. They can change the structure and presentation of documents according to different users, environments and applications, and even directly start workflows within or between organizations

XML based: XML and XML based structure are the key to intelligent documents. The separation of display and content of XML is also one of the main characteristics of intelligent documents

interactivity: intelligent documents extend the concept of traditional documents, so that electronic documents can interact more directly with databases, application systems or other terminals, and even make the documents themselves change with the changes of software environment

built in business logic: smart documents can have built-in business logic, such as intelligent verification, calculation and security processing. These logic can be a script or an XML program

on demand printing: intelligent documents can realize the preparation and distribution of dynamic documents, and can also realize dynamic automatic updates. Customers can download or print the updated information content as needed, and restore the intelligent documents to paper documents at any time

trace retention and long-term archiving: intelligent documents can meet the format requirements of enterprises for long-term preservation and archiving of electronic files. Not only static archive files, but also dynamic forms, data and security can be archived for a long time with the original appearance in history

high integration: intelligent documents can directly interact with databases or other application systems, or seamlessly integrate with "data-centric, process driven" business systems

Smart Client: the smart document client is used to read, fill in and annotate smart documents. It can be embedded in the IE browser or seamlessly integrated into the user's IT application environment

and offline use: through the smart document client software, users can realize the and offline use of smart documents based on desktop, ie or application system

digital signature and electronic seal: smart documents provide an interface for digital signature: name and data encryption, which can selectively sign and encrypt the contents of documents, and even multiple digital signatures and encryption can be performed on different contents of the same document. The security mechanism can realize the control of domains and fields

ease of use and Implementation: intelligent documents are easy to create, which reduces the application threshold of IT technology, so that ordinary enterprise administrators can directly design their own dynamic management programs - Intelligent documents without knowing how to operate the database and having programming technology
