Data masking or data obfuscation is the process of modifying sensitive data in such a way that it is of no or little value to unauthorized intruders while still being usable by software or authorized personnel. Data masking can also be referred as anonymization, or tokenization, depending on different context.
The choice of tokenization as an alternative to other techniques such as encryption will depend on varying regulatory requirements, interpretation, and acceptance by respective auditing or assessment entities. This is in addition to any technical, architectural or operational constraint that tokenization imposes in practical use.
Vaultless tokenization. This is a type of tokenization used for payment processing that doesn’t require a token vault for storage. Instead, it uses cryptographic devices and algorithms to ...
Data masking of structured data is the process of obscuring (masking) specific data within a database table or cell to ensure that data security is maintained and sensitive information is not exposed to unauthorized personnel. [7]
Ultimately, your information is useless and unreadable to fraudsters when encryption and tokenization are used together. Even if a particular retailer you shopped at is hacked, your personal ...
Another early mechanism for format-preserving encryption was Peter Gutmann's "Encrypting data with a restricted range of values" [10] which again performs modulo-n addition on any cipher with some adjustments to make the result uniform, with the resulting encryption being as strong as the underlying encryption algorithm on which it is based.
Public-key encryption was first described in a secret document in 1973; [15] beforehand, all encryption schemes were symmetric-key (also called private-key). [ 16 ] : 478 Although published subsequently, the work of Diffie and Hellman was published in a journal with a large readership, and the value of the methodology was explicitly described ...
Format-preserving encryption (FPE), refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext) Blinding is a cryptography technique by which an agent can provide a service to a client in an encoded form without knowing either the real input or the real output.
