The protection of network privacy is a systematic project, which requires not only the protection of relevant laws and regulations, but also the self-discipline of all internet-related industries and the self-protection of netizens when using the network. It can be said that the self-protection of netizens is the first important link of network privacy protection. Netizens have many ways to protect their online privacy.
The first is to isolate personal information from the Internet. When there is important information in a computer, the safest way is to disconnect the computer from other computers connected to the Internet. This can effectively avoid the invasion of personal data privacy and the economic loss caused by database deletion and modification. In other words, it is best not to store important personal information in the computer that netizens use to surf the Internet. This is also a common practice in many units at present.
The second is to use encryption technology when transmitting files involving personal information. In computer communication, information is hidden by cryptographic technology, and then the hidden information is transmitted, so that even if the information is stolen or intercepted in the transmission process, the thief cannot know the content of the information. The sender uses the encryption key to encrypt the information through encryption equipment or algorithm, and then sends it out. After receiving the ciphertext, the receiver uses the decryption key to decrypt the ciphertext and restore it to plaintext. If someone steals it in transmission, they can only get incomprehensible ciphertext, thus ensuring the security of information transmission.
Third, don't leave personal information on the Internet easily. Netizens should be very careful to protect their information, and don't casually disclose personal information including email addresses online. Now, some websites require netizens to obtain certain "membership" services through registration, and some websites encourage netizens to leave personal information by giving gifts. Netizens should pay great attention to this. Just because a form or application needs to fill in personal information doesn't mean that you should disclose it automatically. If you like, you can turn passivity into initiative and use some false information to deal with the excessive demand for personal information. When asked to input data, you can simply change the letters of name, postal code and social security number, which will associate the input information with false identity, thus resisting the technology of data mining and feature testing. Be more careful about personal information that uniquely identifies the identity class, and don't disclose it easily. This information can only be used for online banking, passport reapplication or dealing with trusted companies and institutions. Even if you must leave personal information, you must first determine whether there are policies and measures to protect the privacy and safety of netizens on the website.
The fourth is to install a firewall in the computer system. Firewall is a way to ensure network security. Firewall can be installed on a separate router to filter unwanted packets, or it can be installed on the router and the host. In terms of protecting network privacy, firewall mainly plays the role of protecting personal data security and personal cyberspace from illegal invasion and attack.
The fifth is to use software to counter Cookie and completely delete files. As mentioned above, websites that set up Cookie information can read the personal information of netizens with the help of browsers, and track and collect their online habits, which poses a threat and violation of personal privacy. Netizens can take some software technologies to counter Cookie software. For example, All in One Secretmaker is a software that combines seven powerful tools: anti-spam, pop-up killer, Cookie deletion, history deletion, privacy protection, slogan interception and worm capture. In addition, because some websites will send some unnecessary information to the computers of network users, netizens can also protect their network privacy by clearing the data temporarily stored in memory after surfing the internet every time.
Sixth, the protection of minors' network privacy should be carried out with the help of parents or guardians and related software technologies, in addition to educating minors on privacy knowledge and media literacy.
