You can’t un-ring a bell, but you might be able to un-hash an email, depending on whom you ask. In order for marketers to safely use hashes for targeted advertising, they must stay abreast of the ...

Passwords are the keys to our online identities, and as a result, they’re also near the top of the target list for attackers. There have been countless breaches in the last few years in which ...

The National Institute of Standards and Technology (NIST) this week opened a competition to develop a new cryptographic hash algorithm, a tool that converts a file, message or block of data to a short ...

Audio hashing transforms raw audio signals into compact, fixed-length representations that capture perceptual characteristics, thereby facilitating rapid identification and verification of audio ...

Hashing refers to the process of using an algorithm to transform data of any size into a unique fixed sized output (e.g., combination of numbers). To put it in layman’s term, some piece of information ...

Last week, the Technology Workgroup of the Massachusetts State HIE Advisory Committee was asked to address an interesting policy and technology question. When a payload of data (a clinical summary, a ...

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

Researchers have found a new way to attack the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates that secure major websites, making it more urgent than ever to retire it ...

Image hashing is a critical technology in digital imaging that converts a visual representation into a compact, binary code uniquely reflecting its perceptual content. This technique is especially ...
