信息技术的飞速发展和广泛应用,使电子文件逐渐成为人类社会记录、传递和储存信息的重要工具,并将成为社会文件的主要形式。电子文件是一种不能直接识读而必须依赖于特定设备和软件才能读取的信息,具有一些与生俱来的致命弱点和难以克服的脆弱性:易于传播,但易改动、易消失、易被窃取。如一些六七十年前的录音带、四五十年前的录像带,今天因为找不到播放它们的设备而成为死的物件而非活的信息。 With the rapid development and widespread application of information technology, electronic documents have gradually become an important tool for human society to record, transmit and store information and will become the main form of social documents. Electronic documents are information that can not be directly read but must rely on specific equipment and software to read, with some inherent fatal weaknesses and insurmountable vulnerabilities: easy to spread, but easy to change, easy to disappear, easy Stolen For instance, some audio tapes from 1960s and 1970s, videos from 40 to 50 years ago, were dead objects rather than living because they could not find the equipment to play them today.
