How are you?Hope so everyone would be safe and sound just like me as I am also safe Alhamdulillah...

Today my topic for discussion is privacy preserving cryptographic protocols.

Source

Privacy preserving cryptographic protocols are designed for the protection of sensitive data but they remain still able for sharing of data and for making analysis. These are the protocols which are used for ensuring that personal data would remain confidential still when they will be processed or shared with any third party.Msin motive behind is for maintainence of privacy while still permitting for useful computations and insights.

There are different types of privacy preserving cryptographic protocols which are below;

Homomorphic Encryption

Homographic encryption is used for enabling of computations on encrypted data without any need of decryption.

Secure Multi-Party Computation

Secure multi party computation is used for permitting of multiple parties for jointly computation of a function without exposing their inputs.

Zero-Knowledge Proofs

Zero knowledge proofs are used for enabling of one party for proving a statement without exposing any underlying or sensitive data.

Differential Privacy

Differential privacy is used for adding noise to data for preventing individual identity and for maintainence of aggregate accuracy.

Secret Sharing

Secret Sharing is used for spliting of data into shares which makes it tough for reconstruction without all shares.

Now I am going to talk about applications of these protocols.

• Security of sensitive data sharing and for collaboration.

• Used for privacy preserving machine learning and in artificial intelligence field.

• Used for securing voting systems.

• Used for analysis of confidential information and for reporting.

• Used for identification ,verification and authentication of sensitive information.

There are some of benefits of these protocols that are below;

• Helpful in protection of sensitive information

• Useful for enabling of secure data sharing and collaboration

• Useful for maintainence of data transparency and security

• Supporting of compliance with data protecting regulations

• Facilitation of security and privacy data analysis

** Some of associated challenges and limitations are here;**

• It cause computational expenses and efficiency

• It involves with much complexity and scalability issues.

• Leads to difficult key management and distribution in proper way.

• Difficulty in standardization and interoperability.

• More disturbance in balancing of privacy and utility

**Some future directions could be followed are here;

• Trying in more developments and advancements in cryptographic techniques

• We can interfering with emerging technologies like blockchain, quantum computing etc.

• Working for development of high efficient and scalable protocols is important.

• Significant adoption and standardization could be kept in mind.

• ddressing legal and societal implications could be another important thing to follow.

By usage of privacy-preserving cryptographic protocols many users and particularly organizations can helps in protection of sensitive data while giving leverage to data for deeper insight , development and innovation.
