Tips to Enhance Data Privacy With Advanced Encryption Techniques

by Uneeb Khan

Data transmission is surging at unprecedented rates, and data privacy is becoming crucial for a business’s basic existence. Enhancing data privacy with advanced encryption techniques is becoming mandatory in the present world. Data encryption converts data from a readable format to a crumpled piece of information. Data encryption can be activated on documents, files, messages, or any other form of communication over a network. Encryption techniques must be heterogeneous to safeguard sensitive information from hackers. 

As cyber-attacks increase and data leaks hike, encryption techniques are evolving daily to strengthen data privacy. The experts who provide managed IT services in Philadelphia will help you implement the latest data encryption technologies that ensure data security by engaging a competent strategy. In this blog, let’s review some practical tips for improving data privacy using advanced encryption techniques. 

1. Understanding  Encryption Fundamentals

Encryption is the main part of data privacy. It converts plaintext data into ciphertext using mathematical algorithms and encryption keys. Decryption is the reverse process. The two primary types of encryption are symmetric and asymmetric encryption.

Symmetric Encryption

This method requires the sender and receiver to access the same key, so the recipient must have the key before the message is decrypted. This method works best for closed systems with less risk of third-party intrusion. Symmetric encryption is faster than asymmetric encryption. However, on the negative side, both parties need to confirm that the key is stored securely and available only to the software that requires it. Prominent symmetric encryption algorithms include AES (Advanced Encryption Standard), which provides high security and efficiency.

Asymmetric Encryption

This method employs two keys for the encryption process: public and private keys. Furthermore, they are mathematically linked. The user goes with one key for encryption and the other for decryption. You can also start with any key that fits your choice. RSA ( Rivest-Shamir-Adleman)and ECC (Elliptic Curve Cryptography) are the common asymmetric encryption algorithms. 

2. Implementing End-to-end Encryption (E2EE)

End-to-end encryption (E2EE) ensures that data remains encrypted from the sender to the recipient, lessening the risk of interception by a third party. It is a type of messaging that keeps messages private from everyone.                                                                                                               

3. Secure Key Management

Proper key management is essential to maintaining the integrity of encryption systems. Organizations should employ secure key storage mechanisms, implement key rotation policies, and enforce strict access controls to safeguard encryption keys from unrecognized access.

4. Data Masking and Tokenization

Data masking and proof techniques protect sensitive data while preserving its usability. Data masking involves replacing sensitive information with fabricated but realistic values. On the other hand, tokenization substitutes sensitive data with non-sensitive tokens. It reduces the risk of exposure in case of any violation.

5. Multi-factor Authentication (MFA)

Multi-factor Authentication (MFA) acts as an outer layer of security. Many verification questions are raised before the client uses the particular data and the security is confirmed. This multiple set of queries ensures that only the authenticated person reaches it. Combining passwords with biometric authentication or one-time code improves data privacy by reducing the likelihood of unauthorized penetration.

6. Data-at-rest Encryption

Encrypting data stored in databases, file systems, and storage devices protects it from unauthorized access. Data-at-rest encryption ensures that sensitive information remains encrypted and inaccessible without proper authentication. 

7. Systematic Security Audits and Updates

While conducting regular security audits, any weaknesses in the encryption techniques are identified and can be corrected on time. It is necessary to keep the encryption software and systems up-to-date to reduce evolving threats and vulnerabilities. 

8. Employee Training and Awareness

Employees in every organization should be aware of the need for data privacy and, thus, the encryption techniques. Training programs must cover encryption fundamentals, secure data handling procedures, and guidelines for recognizing and reducing security threats. Periodic training awareness programs should be conducted to keep the workers up-to-date with progressive technologies in the field of data encryption. 

9. Compliance With Regulatory Standards

Compliance with regulatory standards directs the implementation of robust encryption measures to protect sensitive data and ensure regulatory compliance. That includes  GDPR (General Data Protection Regulation), HIPAA (Health Insurance Portability and Accountability Act), and PCI DSS (Payment Card Industry Data Security Standard).

10. Homomorphic Encryption

It enables computation on encrypted data without decrypting it, offering privacy-preserving data processing capabilities. Homomorphic encryption is of different types. It can be either additive or multiplicative while also being partially, somewhat, or fully homomorphically encrypted:

  • Partially homomorphic encryption: A systematic operation can be performed infinite times on the ciphertext. These schemes are relatively easy to design.
  • Somewhat homomorphic encryption: Here, a limited number of addition or multiplication operations are allowed instead of an infinite number of one operation. Designing a homomorphic encryption system that supports a set number of operations is more difficult than one operation infinite times.
  • Fully homomorphic encryption: This encryption mode allows for an infinite number of additions or multiplications for ciphertexts. Applications for any functionality can be run on encrypted inputs to produce an encrypted output.

11. Transport Layer Security  (TLS)

Transport Layer Security employs a diverse cryptographic algorithm to provide a secure communication channel. That includes symmetric encryption algorithms like AES (Advanced Encryption Standard) and asymmetric algorithms like RSA and Diffie-Hellman key exchange. TLS also supports various hash functions for message integrity, such as SHA-256. It ensures that data remains confidential and unaltered during transit.

12. Securing Cloud Services

In this digital era, when organizations are transitioning to the cloud, security is important. Its benefits include centralized security, reduced costs, reduced administration, and reliability. Strong encryption algorithms such as AES-256 are advised for encrypting sensitive data. The database should be equally secure when it comes to cloud storage. Leverage databases that support built-in encryption, like Transparent Data Encryption (TDE) for SQL databases.                                                                                               


In conclusion, enhancing data privacy with advanced encryption techniques requires a comprehensive approach that encompasses strong encryption algorithms, secure key management, end-to-end encryption, and ongoing monitoring and compliance efforts. By implementing these tips and best practices, organizations can significantly improve their data privacy posture and lessen the risk of data violations and unauthorized access.
