Summary In daily life, we often use computers and USB mobile hard drives to save or send some important files. However, people often do not encrypt these important files. It is precisely because of people's lack of security awareness that information leakage incidents have occurred frequently in recent years. In the past people's cognition, encrypting files is too cumbersome, which is why many people are unwilling to encrypt files. In fact, encrypting information is not difficult. The following article will introduce to you a simple and effective file encryption method.
I. Introduction and analysis of leakage incidents in recent years
• Information disclosure vulnerabilities exist in Huawei PCManager versions earlier than 9.0.1.66 (overseas regions) and versions earlier than 9.0.1.70 (China regions). Attackers can use this vulnerability to read and write information, so many Huawei users have caused privacy leakage due to this vulnerability.
• On August 28, 2018, the sale of occupancy information and data of multiple hotel chains under Huazhu suddenly appeared on the Internet, which aroused widespread concern from users. After all, the data involved 500 million pieces of user personal information and occupancy records, and these The leaked data contains a lot of private information, such as ID number, home address, bank card number and so on.
• In 2018, Amazon employees used intermediaries to sell internal data and other confidential information to third-party merchants, thereby building an advantage for those merchants who bought the data.
• In October 2019, Cathay Pacific issued an announcement announcing that approximately 9.4 million passenger data had been accessed without authorization, including passenger names, nationalities, dates of birth, phone numbers, etc., as well as 0.86 million passport numbers, 24.5 million Hong Kong identity card numbers.
• On June 16, 2018, someone began to sell user information of the recruitment website 51job.com (51job.com, NASDAQ:JOBS) on the dark web, which involved 1.95 million user resumes. Later, 51job confirmed that some user account passwords had been hacked. Hit library. In order to confirm the authenticity of the leaked data, 51job also conducted certain tests and found that the information is true and reliable.
Whether it is being hacked or being sold user information by employees, the cause of these cases is that the data has not been encrypted to a certain extent. If the company performs certain processing on these data or files (for example: encryption or locking, etc.), Then the occurrence of such leakage events can be avoided to the greatest extent.
II. Reasons and countermeasures for file information leakage on the computer
In recent years, many companies like to save some company’s confidential files on the computer, but because these files are not encrypted, the leakage of the files has caused heavy losses to the company. In addition to companies, many users like to put personal information files on the computer, but the files are not protected, so the files are illegally stolen by others. It is not difficult to completely solve the file leakage problem caused by these two reasons, we only need to use - Renee SecureSilo This software can easily solve the problem of computer file leakage.
Renee Secure Silo is one of the most widely used encryption software in the market. The biggest advantage of using this software for encryption is its convenience and security. The user creates a private disk and puts the files to be protected on the private disk to protect the files.
Easy to modify – The software adopts the method of creating a virtual disk for encryption. When using it, create a virtual disk, put files in it, and close the virtual disk when it is not needed. The operation is very convenient. Moreover, unlike encrypted compressed files such as RAR/ZIP/7ZIP, modifying the files in the SecureSilo virtual disk does not require a long wait, and the modified or newly added files can be saved in less than a second.
Good security – due to the private format of the virtual disk, and the use of advanced AES256 encryption technology. There is no universal cracking program available on the market.

User friendly Concise interface helps users master the software in short time.
Let’s take a look at the specific operation steps of the software:
1. Download and install Renee SecureSilo.
2. After the download is complete, open the software, and set a login password for the software in the pop-up interface. (You will need to enter a password each time you log in).
3. Click on the encrypted file and select “Create Private Disk” to create a virtual disk.
4. After creating the virtual disk, set an open password for the virtual disk.
5. After setting the password, select the size range of the disk, then click “Next” and wait for the encryption to complete.
6. The user puts the files to be encrypted into the created virtual disk, and then closes the private disk to complete the locking.
7. The user only needs to enter the password to open the private disk. After the virtual disk is opened, you can see screenshots of various files in the windows file browser.
8. If the user needs to delete the private disk, then open the software, select the private disk in the encrypted file interface, then click “Edit Private Disk”, then select “Delete”, select “Yes” in the pop-up prompt box, and then ” Enter the password” and that’s it.
III. Causes and countermeasures of information leakage in remote information transmission
In addition to the information leakage of the files we store on the computer, if we do not encrypt the transmitted files when we transmit the remote information, the information will also be read and identified by others, and the information will be stolen. So is this phenomenon unavoidable? The answer is no, here we will introduce two professional software for you, so that you can safely transfer information files remotely.
(1) Renee File Protector
Renee File Protector It is one of the most popular and professional file encryption software on the market. Use this software to encrypt emails. This software encrypts files in gfl format or exe format. With the help of this software, the user can encrypt the files that need to be transmitted remotely, so as to realize safe transmission and avoid information leakage during transmission. (However, you need to pay attention to using this software to encrypt emails: if the encryption is in gfl format, then the party receiving the email also needs to download a Renee File Protector to decrypt it. It is not necessary to encrypt it in exe format.)
