Privacy Enhancing Technology Types and Use Cases

There are a variety of different types of privacy-enhancing technologies (PETs), each with its own unique advantages and disadvantages. In this article, we will explore some of the most commonly used PETs, as well as their key use cases.

What is Privacy-Enhancing Technology (PET)?

Protection is the right of people to control or impact how their data might be gathered, utilized, and put away, as well as by whom and how that data might be revealed. What information individuals give ought not to be followed back to them straightforwardly or from measurable results.

This last prerequisite makes it difficult for ventures to gather and investigate client information to conduct bits of knowledge, to further develop dynamic cycles, and quantify the exhibition of items, clinical preliminaries, or promotion crusades, particularly as this information is frequently imparted to outsiders

Types of Privacy-Enhancing Technologies:

1. Encryption:

Encryption is a process of transforming readable data into an unreadable format using a cryptographic key. This makes it extremely difficult (if not impossible) for unauthorized individuals to access the data. Common uses for encryption include protecting email messages, online communications, and stored data (such as files on a computer).

The most unmistakable and normal type of protecting information is encryption. Encryption is a reversible process that switches information over completely to an indiscernible structure called cipher text; decoding the cipher text changes over the information back into its unique structure (alluded to as plaintext).

Why Encryption

The motivation behind encryption and decoding is to permit just approved clients to get to the plaintext involving a key for change. Regardless of whether unapproved clients gain admittance to the scrambled information or cipher text, they cannot peruse it without having admittance to the key.

Cryptographic calculations, called figures, make arbitrary series of characters to address the basic information. These calculations have relating cryptographic keys, which are likewise strings of characters, and these are utilized together to change the fundamental information into cipher text.

The more drawn out and more intricate cryptographic keys are, the harder it is for an enemy to figure out the code and unravel the basic plaintext information. Encryption can utilize a similar key to both scramble and unscramble information, or different keys.

2. Anonymization:

Anonymization is a process of making data anonymous, such that the identities of individuals cannot be determined from the data itself. This is often done by removing personal identifiers (such as names, social security numbers, and addresses) from data sets. Anonymization can be used to protect the privacy of individuals while still allowing the data to be used for research or other purposes.

The term anonymization is utilized comprehensively in protection conversations and can mean de-ID by and large, or then again allude to explicit methods. For the motivations behind this report, anonymization is the act of eliminating direct, or circuitous, identifiers from a dataset.

Anonymization is one of the first privacy-enhancing methods utilized across businesses and associations; however, it has since ended up being moderately shaky assuming different information sources are joined. The expulsion of identifiers from information can be a manual or computerized process. For mechanized processes, it is vital to affirm that the right data is being eliminated. As talked about above, it is moreover vital to consider when the expulsion of data is attainable for the utilization case.

The expulsion of identifiers from information can be a manual or mechanized process. For robotized processes, it is vital to affirm that the right data is being taken out. As talked about above, it is moreover essential to consider when the evacuation of data is doable for the utilization case. The significant downside to anonymization is that data that was eliminated from datasets can be remade by consolidating data from various sources.

Privacy Introduce

In the 1990s, Dr. Latanya Sweeney tracked down that information that prohibited direct identifiers (name, address, telephone number, and so on) might in any case be utilized to recognize people when joined with different data sets, it is openly accessible to incorporate those that. In particular, she viewed that 87% of the U.S. populace could be recognized by utilizing just their date of birth, orientation, and compress code.

The capacity to extraordinarily distinguish people by joining information from numerous sources has just expanded as the information age and assortment on a worldwide scale has expanded, and delicate informational collections have been uncovered through information breaks. New regulations, like GDPR, recognize this shortcoming and don’t consider eliminating data an adequately solid type of de-ID.

3. Blockchain:

Blockchain is a distributed database that allows for secure, transparent, and tamper-proof record-keeping. It is often used to store digital assets (such as cryptocurrencies) and has potential applications in other areas such as supply chain management and identity verification. Check RemoteDBA.

A blockchain comprises many blocks that themselves consist of hashed bunches of exchanges. An exchange contains information that should be shared safely. Transactions are gathered inside a block in view of the size of the block. The block is sent over to the organization in a synchronized manner that permits every hub to store a duplicate of the blockchain.

4. Zero-knowledge proofs:

Zero-knowledge proofs are a type of cryptographic protocol that allows one party (the prover) to prove to another party (the verifier) that they know a certain piece of information, without revealing any other information. This can be used to verify identities or transactions without disclosing sensitive data.

ZKP is a bunch of cryptographic calculations that empower data to be approved without uncovering information that demonstrates it. It assumes an essential part in character validation. A singular’s age, for instance, can be confirmed with ZKP without revealing their genuine date of birth.

Zero-Knowledge Proofs are again one of the top utilized instances of the best security improving innovations utilized generally across organizations. This innovation utilizes cryptographic calculations in a way to such an extent that it permits affirmation of information without unveiling the hidden information which confirms something very similar.

It upgrades the capacity of a party to demonstrate they have data accessible about another party. Adding further to accommodation, the earlier party needs to disperse no other valuable data about the reality to the last option.

In the space of character verification, the uses of ZKPs can have a vital effect. For instance, ZKPs can be a convenient innovation for verification of a singular’s age without uncovering touchy data, for example, birth date. Essentially they back information minimization and conservation. Further adding to that, ZKPs likewise advance the joining of security as a non-debatable component in return engineering.

5. Trusted platform modules:

Trusted platform modules (TPMs) are hardware devices that store cryptographic keys and perform other security-related functions. They are often used in conjunction with encryption to provide an additional layer of security.

Key Use Cases for Privacy-Enhancing Technologies:

1. Data security:

As mentioned above, encryption is commonly used to protect data from unauthorized access. This is especially important for sensitive data such as financial information or personal health records.

2. Communication privacy:

Anonymization and encryption can be used to protect the privacy of communications, such as email messages or online chats.

3. Identity verification:

Zero-knowledge proofs can be used to verify someone’s identity without revealing any other information about them. This has applications in areas such as online banking and access control.

4. Supply chain management:

Blockchain can be used to track the movement of goods through a supply chain, from production to delivery. This can help to ensure that products are not counterfeit and that they are delivered on time.

5. Research:

Anonymization allows data to be used for research purposes while still protecting the privacy of individuals. This is important for fields such as medicine, where data from human subjects is often used.

These are just a few of the many different types of privacy-enhancing technologies that are available. Each has its own unique advantages and disadvantages, so it is important to choose the right one for your specific needs. In general, however, these technologies can be used to improve the privacy of data, communications, and transactions.
