How Can Privacy Enhancing Technologies Help Different Sectors?

With continuing large-scale data breaches and leaks, it has become apparent that you need better ways to protect your information. The global cybercrime damage in 2021 amounted to $16.4 billion a day. It shows that current security practices are not working and that you must find new ways to protect your data.

There are many privacy enhancing technologies, each with strengths and weaknesses. This article will explore how such technologies can help different sectors.

Financial Sector

Data encryption is a security method that encodes information and cannot be decrypted or accessed unless the user has the correct encryption key. For example, data encryption protects information, such as credit card numbers, online banking details, and transaction records in the finance sector. Several data encryption algorithms are used to encode and decode it. The Advanced Encryption Standard (AES) is the most common type of algorithm. AES uses a symmetric-key algorithm, which means the same key is used to encode and decode data. AES is a block cipher that encrypts data in blocks of 128 bits. The larger the block size, the more secure the encryption. AES can use three key sizes: 128, 192, or 256 bits. The U.S. government uses AES with a 256-bit key to protect classified information.

Healthcare Sector

It is crucial to have privacy when it comes to healthcare. There are many ways in which technologies can ensure privacy and help the healthcare sector. One way is by providing that only authorized personnel access patient information.

Another way is ensuring that patient information is not shared with any third party without the patient’s consent.

Healthcare organizations can also use modern technologies to anonymize patient data. It will help protect their identities while allowing researchers to access the data for studies.

Privacy enhancing computation is a powerful tool that can help the healthcare sector in many ways. Therefore, it is essential to implement these technologies to protect patient privacy and data security.

Retail Sector

If you are in the retail sector, you know that customer data is essential to your success. But what happens when that data falls into the wrong hands?

That’s where such technologies come in. These can help protect your customers’ info while allowing you to use it for marketing and other purposes.

Some of the ways the technologies can help the retail sector include:

  • Providing a way for customers to opt out of data collection
  • Allowing customers to choose what info is shared and with whom
  • Giving customers control over how their information is used
  • Helping businesses keep customer data secure

Government Sector

Government firms like the U.S. Census Bureau handle a great deal of sensitive information. In the past, this data was collected and stored on paper, then processed by hand. Unfortunately, this system was inefficient, leaving the information vulnerable to tampering and theft.

When private information is stored electronically, it can be accessed and shared more easily than paper records by expert hackers. With the advent of computers, government agencies began to digitize their data collection and storage processes. It helped improve efficiency and privacy but also created new risks.

Government agencies increasingly turn to modern computation methods to protect the sensitive information they collect and store. These can help to prevent unauthorized access to data.


Whether you are a business, government institution, or individual, there are many ways that you can use privacy enhancing technologies to protect your data. These technologies can help you keep your data safe from hackers, ensure that your communications are private, and help you prevent identity theft.
