Computer examination means that students' examination process is carried out directly on the computer, and there is no need to use pen and paper to take the examination. Now many examination items have implemented paperless superior examination, which is a kind of progress and the future examination direction.

Paperless is an ideal goal of information process, which involves paperless kitchen, paperless transaction, paperless office, paperless reading, paperless examination, even paperless society and so on. The realization of this goal itself is a gradual, sustainable development and gradual understanding process. It is a systematic project, involving technical realization, legal perfection, social application, institutional innovation and many other aspects. The key is technical realization. In order to solve the problem that electronic information can remain original, complete and undeniable for a long time, the current legally recognized scheme is to use data messages in the form of format files. The most basic thing is to improve the law. To solve the problem of recognition, clarification and perfection of laws and systems, the Model Law of the United Nations Commission on International Trade Law and China's Electronic Signature Law have made macro provisions on this, but they are rarely implemented in specific procedural laws. The most important thing is to solve the problems of user habits, interest pattern, marketing operation and maintenance, breaking through tradition and so on through the pilot and verification of social application and institutional innovation, especially to realize that this is not an act of quick success and instant benefit, and to overcome the negative attitude of waiting and waiting. The process of promoting ideals and science is: first, we should solve the problem of paperless from the technical realization, then verify the feasibility of paperless through social application and institutional innovation, and then realize the legitimacy of paperless through combing and perfecting the legal system, and continue this process of verification and improvement to achieve the sustainability of paperless.
