  • PII Redaction and Reversible Tokenization in Production LLM Systems: Architecture, NER Latency, and Streaming De-Anonymization

    In enterprise production environments, forwarding unsanitized prompt payloads to third-party model providers or logging raw agent execution traces exposes organizations to severe regulatory liability. Under frameworks such as GDPR Article 4(1), the HIPAA Safe Harbor standard, and the California Privacy Rights Act (CPRA), personally identifiable information (PII) including patient health identifiers, Social Security numbers, credit card data, full names, and personal email addresses cannot be tra

  • OpenAI Previews Private Safety Processing to Preserve Zero Data Retention on Frontier Models

    OpenAI has previewed Private Safety Processing, a safety architecture designed to detect multi-turn misuse patterns across frontier model interactions while maintaining Zero Data Retention (ZDR) privacy guarantees for enterprise API customers. Under traditional Zero Data Retention agreements, API customer prompts and generated outputs are not stored on OpenAI servers post-request, are inaccessible to OpenAI personnel, and are excluded from model training datasets. However, evaluating requests s

  • OpenAI's Computer History turns your Mac activity into a searchable ChatGPT memory

    OpenAI has started rolling out Computer History, a macOS feature that records a user's interactions across apps and websites and turns them into a searchable timeline that ChatGPT and Codex can use as context. Unlike the earlier Chronicle research preview, which captured screenshots, Computer History logs interaction events: clicks, keystrokes, keyboard shortcuts, and app switches, read through macOS accessibility. OpenAI says it does not capture screenshots, screen recordings, microphone input

  • Twitch lets streamers block their content from Amazon's generative AI training

    Twitch lets streamers block their content from Amazon's generative AI training Twitch has quietly added a control that lets creators stop their streams, clips, and chat from being used to train Amazon's generative AI models. The setting, labeled "Training for Generative AI," sits in the Security and Privacy tab of account settings and is live now, but it arrives with a design that puts the burden on users to find it. What the toggle actually blocks Flipping the control off excludes a d

  • Researchers can now read the hidden reasoning inside frontier AI APIs

    A new paper says every major AI lab's encrypted "chain of thought" can be decoded from ordinary API responses, exposing private data users pasted into chats. Since OpenAI's o1, frontier labs have hidden their models' step-by-step reasoning behind cryptographic signatures, fearing rivals would distill it. The protection was supposed to be a hard confidentiality barrier. It was not. A team led by Alexander Panfilov and Jonas Geiping showed that a legitimate signed reasoning block pulled from one

  • Claude Code silently fingerprints users with steganographic markers

    Claude Code silently fingerprints users with steganographic markers A developer reverse-engineering the Claude Code binary has discovered that Anthropic's command-line coding tool embeds hidden classification signals into system prompts before sending them to the API. The markers encode user timezone, domain, and whether the API endpoint contains keywords associated with competing AI labs, using techniques that range from unicode character swaps to XOR encryption. The findings were published
