It's trivial to reverse cryptographic hash functions if you know the input consists of names, social security numbers, etc. from a limited set of possible values.
Robustness of Practical Perceptual Hashing Algorithms to...
Perceptual hashing algorithms (PHAs) are widely used for identifying illegal online content and are thus integral to various sensitive applications. However, due to their hasty deployment in...

Concrete ML: Privacy Preserving ML framework using Fully Homomorphic Encryption (FHE), built on top of Concrete, with bindings to traditional ML frameworks.
Introducing OpenAI Privacy Filter
OpenAI Privacy Filter is an open-weight model for detecting and redacting personally identifiable information (PII) in text with state-of-the-art accuracy
How Google is Making Private AI Practical with Homomorphic Encryption
Today we're excited to showcase HEIR, the latest powerful tool added to our Private Computing Toolkit. HEIR is an open source compiler that unlocks cryptographically-sec…
Privacy, human rights, and Tornado Cash
I am more worried about privacy than crypto crime.
Differential Privacy
A robust yet accessible introduction to the idea, history, and key applications of differential privacy—the gold standard of algorithmic privacy protection
Differential Privacy
In 1977 Dalenius articulated a desideratum for statistical databases: nothing about an individual should be learnable from the database that cannot be learned without access to the database. We give a general impossibility result showing that a formalization of Dalenius’ goal along the lines of semantic security cannot be achieved. Contrary to intuition, a variant […]
Tinfoil - Private AI
AI that keeps your data private at all times. Fast, powerful, and verifiable, thanks to secure hardware enclaves.
Apple Intelligence Promises Better AI Privacy. Here’s How It Actually Works
Private Cloud Compute is an entirely new kind of infrastructure that, Apple’s Craig Federighi tells WIRED, allows your personal data to be “hermetically sealed inside of a privacy bubble.”
FR#163 – Decrypting Matrix
On the convergence towards private data on social networking protocols, and the connection to Matrix
Bab
Bab is a family of secure hash functions, heavily inspired by BLAKE3. Bab hashes allow for streaming verification of strings, similar to the BLAKE3-based Bao algorithm. We discuss several optimization techniques that go beyond the Bao specification. Further, unlike BLAKE3 and Bao, Bab digests allow for constant-sized length proofs of their strings.
Hash Functions for GPU Rendering – Nathan Reed’s coding blog
Pixels and polygons and shaders, oh my!
