DATA SECURITY
ENCRYPTION
Ever feel like your data needs a bodyguard? Enter
Encryption. Encryption scrambles your data using
a secret key, making it unreadable to anyone
without the key. Imagine it like a locked box -
only someone with the key can access what's
inside! Protects data in transit (HTTPS) and at
rest (hard drives).

MASKING
KEEPING IT DISCREET
Working with sensitive data but don't need the
real thing? Masking is here to help! Masking
replaces real data (like Social Security numbers)
with realistic but fictional substitutes. Think
of it like putting on a disguise to protect your
identity! Protects data privacy in development
and testing.

STEGANOGRAPHY
SECRETS IN UNEXPECTED PLACES
Did you know you can hide messages in plain
sight? Steganography is like magic! This
technique embeds messages within other files,
like images or audio, making them invisible to
the naked eye. While not super common today, it
can be used for secure communication.

ENCODING
SPEAKING THE SAME LANGUAGE
Data needs a translator sometimes! Encoding
converts data into a different format for easier
transfer and processing. Imagine translating a
language so different systems can understand each
other. Ensures data is in the correct format
(e.g., HTML encoding).

TOKENIZATION
REPLACING SENSITIVE DATA WITH TOKENS
NFT
Worried about credit card details during
transactions? Tokenization is your knight in
shining armor! This clever method replaces
sensitive data with unique tokens. A separate
system securely stores the link between the
tokens and the original data. Protects sensitive
information during transactions (e.g., credit
cards).

PSEUDONYMIZATION
PROTECTING PRIVACY WHILE STUDYING DATA
An important tool for data analysis,
Pseudonymization helps protect privacy. This
process replaces personal identifiers (like
names) with pseudonyms. Data can still be
analyzed for trends, but it doesn't directly
identify individuals. Enables privacy-enhancing
data analysis (e.g., research).

HASHING
THE DATA FINGERPRINT
Ever wonder if your data has been tampered with?
Hashing can tell! Hashing creates a unique
fingerprint (hash) for your data. Any changes to
the data will result in a different hash,
indicating tampering. Used for password storage,
file integrity checks, and digital signatures.
