The mobile device is portable, it may record your position at all times, the use of the search engine, it may put your purchase intention thoroughly analysis out; e-mail Network archive, it may leak user privacy ...

This is the convenience of the internet to the real life, it records the user's digital footprint, but the user network payment password may be stolen, e-mail may receive hundreds of spam every day, or other worse things happen. Because the Internet, users of personal privacy leaked news on the major IT news newspaper or website headlines, if the network users or casual surfing in the network, then one day, very likely in the café, the use of WiFi was stolen online bank account. The current online second-hand trading market, second-hand computer turnover is very good. But most people don't erase personal information from hard drives. In the end, what precautions can be used to ensure that the user's business is not affected by the premise of protecting enterprise sensitive information, commercial secrets?

Comprehensive coverage of secure network channels has become an urgent task for enterprises. Secure channel encryption means that the enterprise does not have to worry too much about the encryption of routers or clients, can establish a transparent database, simplify the management and security of the database. A bad security environment can be fatal to an enterprise. This is similar to a door lock, a car alarm, with these safety precautions, at least to get the thieves elsewhere. Here are a few examples of data theft.

Privacy Protection Cookie Management technology

The search engine that tracks users ' mobile online is good for advertisers, and it helps with precision marketing. Accurate advertising marketing is the lofty goal of every advertiser.

The standard mechanism for online tracking is to store cookies in your browser. Every time you return to a website, your browser silently sends the cookie back to the server and then connects you with previous visits. These personalized information sticks can stay for a while unless you set your browser to delete them.

Most browsers have enough tools for page analysis and to delete specific cookies. Some advertising companies have been trying to dig into the operating system. Cleaning cookies is not necessarily a big help.

Data protection The Onion Rou

One of the easiest ways to track a computer is through an IP address, and the internet is like a phone number that allows you to request data that can be found in your own way back to the computer. IP addresses can be changed on some systems, but they are often relatively static and malware can often be traced to.

A well-known tool can avoid this type of tracking, the English name is called "The Onion Rou". It can create a self-healing, encrypted supernetwork on the Internet. When your computer starts is a link to the Tor network, a path drawn through the Tor subnet through n different intermediate nodes. Your Web page request through n nodes, along this path can be encrypted n times, each node can be encrypted over the network. Information in the end of the last machine, can encrypt the page n times, which makes the computer through that channel to another machine is a mystery, the other one by one machines do not find your IP, you can not find another machine IP, this is a trusted Tor network. A generic email is the use of Tor to compile your own complex code.

SSL Technology for data protection

An encrypted SSL connection is a very simple security mechanism. If you have a website with the prefix "HTTPS", through the complex algorithm for information exchange and encryption. Many e-mail service providers, such as Gmail, now encourage you to use HTTPS to connect to your privacy, which allows users to switch their browsers to a more secure level.

An SSL connection that can disrupt data publishing to a Web site. If you are reading or sending an email, the SSL connection will hide your relationship with any computer or router. If you want to surf the Internet through a public Wi-Fi place, using SSL can block websites or anyone from accessing your computer.

SSL can only protect your computer and Remote Web site information, but it does not control what the site does. If you are reading your email and web browser, SSL encryption will prevent others from viewing your mail, but it will not prevent web emails from customizing ads for customers.

There are many sophisticated technologies that can be used to subvert SSL connections, such as the poisoning certification process. If you're using a local café Wi-fi,ssl may tell you what to pay attention to, like telling you that someone behind you is attacking you.

Encrypted messages for data protection

Although Tor hides its own IP address and SSL will protect your data but only encrypted messages can protect your information, encrypted algorithms are like scrambled characters, tying random characters together and taking place to the addressee. The recipient is the only one with the password key.

Encrypted messages are more complex than SSL encryption software, and both must run compatible software and establish the right links. At a time when encryption is booming, there are many problems and limitations, such as the misuse of administrator rights, which is a deadly threat to message encryption.

Translucent database for data protection

Typical Web sites or repositories are stored in a database, and most of the information is stored in clear text, which is likely to be the target for hackers to steal data. The traditional solution is to use strong passwords to create a data wall, but once someone crosses the data wall, it's easy to access the data.

Some database solutions are typically "semi-transparent databases." Many databases provide additional cryptographic tools to easily add other encrypted Web clients. The best example is to encrypt sensitive data.

Implicit writing of data protection

Steganography is one of the most elusive techniques. Traditional encryption still has security implications, but steganography allows privacy data to be hidden in many data. For example, the city's potted plants or a cat, they put indoors will not cause hackers attention.

The most common approach to steganography involves a small number of files that are often not noticed. For example, you can hide the red and green scenes in a single pixel. If two sets exist at the same time, the pixel carries an even number, and the data information is 0. If the green and blue scenes are pure at the same time, they represent odd numbers, and the data information is 1. Such a simple pixel problem is hidden in a file, its existence is tiny, difficult to be discovered by hackers, only use the correct calculation method, can find this information.

But covert writing is not the most perfect. As the pixel of the picture may change in the course of the transmission, the red and green, the subtle changes in the blue pixel are not visible to the naked eye, and the contents of the hidden writing may change. But the scientists who work on tests are very fond of steganography, which is like looking for hidden data in Cat-and-mouse games.
