How do I encrypt my audio files?

If you’ve got your MP3/WAV files ready for transcription services, it can be a good idea to encrypt them to keep the data secure – especially if the content is sensitive. 

File encryption helps protect the content of your files by encrypting them (converting them into a code). Only someone who has the correct encryption key (ie. a password) can decrypt this back into an understandable format. 

The good news is, there are many options to choose from, some more simple than others. 



Using 7-Zip or an Alternative Zip Programme

A popular way of encrypting your audio files is by using a free programme such as 7-Zip. When using this, you’ll have the choice of using a password to encrypt the file.

In order to encrypt the MP3/WAV, it will need to compress the file into a zip file – so don’t compress it beforehand. A zip file is basically a squashed down version of your MP3 file.

You can either use 7-Zip or download a similar zip file compression software onto your computer which includes the option of adding a password. 



Encrypting Files on Windows

If you are using Windows hardware on a computer or laptop, you can encrypt your files within your computer system. 

First off, locate your required audio file within your computer system. Right-click on this, or press and hold, and select ‘properties’ from the options which appear. 

Then, select the ‘advanced’ tab and tick the ‘encrypt contents to secure data’ box. Make sure that you then select ‘ok’ when closing the advanced attributes window. Click apply and then select ‘ok’. 

Windows file encryption only protects your files against anyone who gets their hands on your computer. This type of encryption is connected to your Windows account, so when you log into your computer, the files will decrypt automatically due to the operating system. However, if someone else were to log into your computer from another account and attempt to access your files, they would not be able to get to the ones that were encrypted under your username.



Encrypting Files on Mac

Encrypting on a Mac works a little differently than Windows. This way allows you to password protect your folder.

Create the folder you would like to encrypt, containing the audio file with sensitive content. Then, go to Disk Utility. Once this is opened, click ‘File’, then ‘New Image’, and then ‘Image from Folder’. This will open up your documents, where you can locate your folder and select a method of encryption. 

Create a strong password here and click save. You’ll be ready to go!



Or, cut out the fuss and upload through our safe and secure, encrypted website uploader!

At Transcribe It, we use multiple methods of encryption to keep your files stored securely. This confidentiality is paramount to us, and we are very committed to ensuring our customers feel confident that their information is protected. 

All of our files are kept in an encrypted AWS (Amazon Web Services) bucket. As Amazon is held responsible for the security of the data kept on here, they continuously monitor their cloud infrastructures for unusual and suspicious-looking activity. AWS also offers tools and special features that allow us to see exactly what is happening, which can help to identify activity such as attempts of unauthorized access.

AWS is also held within a UK-based data centre, so UK GDPR regulations are adhered to. The ICO also regulates data protection in the UK, offering advice and guidance and taking enforcement action where appropriate.

When our transcribers work with the files, they are saved on a hard drive which is encrypted with 256 bit AES encryption. 

We regularly review our standard of encryption and make sure it is as up to date as possible.
