When office automation in 80s just started, many people declared that paper would disappear from the office. Automatic machines would replace paper as the new favorite of the office.

As a matter of fact, word processors and personal computers have become new favorites. With the popularity of computers and the establishment and improvement of enterprise management information systems, senior secretaries have been replaced by computers in the past.

However, the use of computers brings convenience and convenience. At the same time, it also has a series of problems that haven't been solved effectively: 1., the surface of the disk is kept intact. Because of the changes in the environment (hardware, software, encryption, encoding, etc.), the information will become unreadable.

The original definition of 2. electronic files is difficult.

Identifying the primordial nature of electronic documents is the key to ensure the effectiveness of their credentials.

The alterability of electronic documents and the separability of information and carriers make possible the alteration of electronic documents in the course of formation or pmission.

3. security issues: attention to the protection of electronic documents "physical life" and "information life".

The "physical life" of protecting electronic documents is mainly to prevent magnetism, control the temperature and humidity of the environment, and prevent mechanical damage.

The protection of electronic documents "information life" is another new challenge.

Therefore, secretaries must not rely too much on computers. In making use of modern information equipment to improve their work efficiency, we must fully recognize their potential problems, do well in preventive work, such as preventing computer viruses, controlling the security of electronic document systems in the network, backup processing, and remote preservation.
