A hash is kinda trash. Or, more precisely, not only will hashing data not anonymize it, but regulators, including the Federal Trade Commission, consider hashed identifiers to be personal information.

In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

Imagine taking a block of data and turning it into a unique string of characters. Like giving it a digital nickname that never changes (unless the data does!). That’s a hash. Whether the original data ...

Hashing techniques have emerged as critical tools in the management and retrieval of large-scale image and multimedia datasets. By mapping high-dimensional data into compact binary codes, these ...

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...
