Summary We frequently use computers and USB drives to store or transfer important files, yet many neglect to encrypt them, leading to numerous information leaks. Contrary to the belief that encryption is cumbersome, it's quite simple. This article will guide you through an easy and effective file encryption technique.
I. Introduction and analysis of leakage incidents in recent years
Information disclosure vulnerabilities have been identified in Huawei PCManager versions prior to 9.0.1.66 (overseas regions) and versions prior to 9.0.1.70. Exploiting this vulnerability enables attackers to access and manipulate sensitive information, leading to privacy breaches for numerous Huawei users.
• On August 28, 2018, the sale of occupancy information and data from multiple hotel chains under Huazhu was leaked on the Internet, causing significant concern. The data breach exposed 500 million pieces of user personal information and occupancy records, including sensitive details such as ID numbers, home addresses, and bank card numbers.
• In 2018, Amazon employees sold internal data and confidential information to third-party merchants, giving them an advantage.
• In October 2019, Cathay Pacific announced that around 9.4 million passenger data had been accessed without authorization. This included passenger names, nationalities, dates of birth, phone numbers, etc., along with 0.86 million passport numbers and 24.5 million Hong Kong identity card numbers.
• On June 16, 2018, user information from 51job.com (NASDAQ: JOBS) was sold on the dark web, including 1.95 million resumes. 51job later confirmed that some user account passwords were compromised. The authenticity and reliability of the leaked data were verified through tests conducted by 51job.
The cause of these cases is the lack of data encryption. Performing processing such as encryption or locking can prevent such leakage events.
II. Reasons and countermeasures for file information leakage on the computer
In recent years, companies and users have faced heavy losses due to the leakage of confidential and personal files stored on computers. To address this issue, the use of Renee SecureSilo software can effectively prevent computer file leakage.
Renee Secure Silo is highly popular encryption software known for its convenience and security. Users can create a private disk to safeguard their files effectively.
Easy to modify – The software utilizes a virtual disk for encryption, allowing for easy modification. Simply create a virtual disk, store files, and close it when not in use. This process is highly convenient. Additionally, unlike RAR/ZIP/7ZIP, editing files in the SecureSilo virtual disk is quick, with modifications or new additions saved in under 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.

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 Silo” 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. To delete the private disk, open the software and go to the encrypted file interface. Click on “Edit Silo,” then select “Delete.” Confirm the deletion by selecting “Yes” in the pop-up prompt box. Finally, enter the password to complete the process.
III. Causes and countermeasures of information leakage in remote information transmission
If we fail to encrypt transmitted files, not only can others read and identify the information, but it can also be stolen. However, this issue can be resolved by using two professional software options for secure remote file transfer.
(1) Renee File Protector
Renee File Protector is a popular file encryption software that allows users to encrypt files in gfl or exe format. It ensures safe transmission and prevents information leakage during remote transmission. Note that if encryption is in gfl format, the recipient will also need to download Renee File Protector to decrypt it. No additional software is required for encryption in exe format.
