• RSA (Rivest-Shamir-Adleman) is a foundational public-key cryptosystem ideal for secure data transmission.
• Elliptic curve cryptography (ECC) provides equivalent security to RSA with smaller key sizes, making it efficient for mobile devices.

Hashing:

• SHA-256 is a part of the SHA-2 family, commonly used for integrity verification and digital signatures.
• Specifically designed for password hashing, bcrypt includes built-in salt to protect against rainbow table attacks.

Other techniques:

• Format-preserving encryption (FPE) encrypts data while maintaining its original format, useful for structured data like credit card numbers.
• Homomorphic encryption allows computations on encrypted data without decrypting it first.

Key considerations for implementation:

• Choose appropriate algorithms based on security requirements and performance needs.
• Implement secure key management practices, including generation, storage, and rotation.
• Use strong, randomly generated keys of sufficient length.
• Encrypt data both at rest and in transit.
• Regularly update and patch encryption systems to address vulnerabilities.

For example, implementing AES encryption can help your company safeguard customer data effectively, preventing the data leakage.

Data masking and redaction

Protecting sensitive information during processing and storage can be achieved through data masking and redaction techniques.

Data masking

This group of approaches is reversible and preserves data format and some utility. Used for testing and access control.

• Substitution replaces sensitive data with realistic but fictitious values.

Original: 1 2 3 4 5
Substituted: 8 9 7 6 2
Each number is replaced with another value that maintains the same format but does not reveal the original data.

• Shuffling mixes values within a dataset to obscure original information.

Original: 1 2 3 4 5
Shuffled: 4 1 5 3 2
The values are the same, but their positions are randomized, which prevents direct associations.

• Nulling out replaces sensitive data with null values.

Original: 1 2 3 4 5
Nulling out: _ _ _ _ _ (or “null null null null null”)
All sensitive data is replaced with nulls, effectively hiding the original information.

• Dynamic masking masks data on-the-fly for unauthorized users, maintaining data utility for specific processes or users.

Original: 1 2 3 4 5
Dynamic masking (for unauthorized users): X X 3 X X
Only specific elements (like ‘3’ here) remain visible depending on the access level, ensuring utility while maintaining security for sensitive parts.

Data redaction

Apart from data masking, these approaches are yypically irreversible, providing strong protection but limiting future utility. Used for legal and classified information.

• Blacking out permanently removes or obscures text in documents.

Original: 1 2 3 4 5
Blacked Out: █ █ █ █ █
The original data is obscured by black blocks, making it unreadable and unrecoverable.

• Deleting removes sensitive data portions completely.

Original: 1 2 3 4 5
Deleted: ” “
All data is removed, leaving a blank space or no content at all, ensuring the sensitive data cannot be retrieved.

• Replacing replaces characters with asterisks or placeholders to obscure original data.

Original: 1 2 3 4 5
Replaced: * * * * *
Each value is replaced with an asterisk or another placeholder, maintaining the data structure but obscuring the specific content.

Best practices

• Choose techniques based on data sensitivity and use case.
