Tokenization

Simple Definition for Beginners: Tokenization is a process of substituting sensitive data with non-sensitive tokens to protect it from unauthorized access. Common Use Example: When making a payment online, your credit card number is tokenized, replacing it with a unique token that can be used for transactions without revealing the actual card details. Technical Definition for Professionals: Tokenization is a security technique that replaces sensitive data, such as credit card numbers or personal identifiers, with non-sensitive tokens. Key aspects of tokenization include: · Data Substitution: Replacing sensitive data elements with unique tokens that have no intrinsic value. · Token Mapping: Maintaining a mapping table that links tokens to their original data for reversibility. · Data Security: Protecting sensitive data at rest and in transit by using tokens that are meaningless outside the system. · Token Format: Tokens can be numeric or alphanumeric, generated using encryption or randomization techniques. · Compliance: Tokenization is often used to comply with data protection regulations like PCI DSS for payment data security.
