Method For Data Exchange Between A Transmitter/Receiver Unit On A Filter Element And A Further Transmitter/Receiver Unit

Defensive Publications Series

The paper is based on the task of enabling secure data exchange between a transmitter/receiver unit on a filter element and another transmitter/receiver fangs unit. This task is solved according to the paper. The method according to the paper is used for data exchange between a transmitter/receiver unit on a filter element and a further transmitter/receiver unit outside the filter element. With the help of the data exchange, in which a data signal is transmitted in encrypted form, a filter element can be identified, for example, so that the installation of a non-matching filter element in a filter housing can …

Retrieval-Augmented Generation (Rag) Classification And Access Control, Assaf Namer, Robert Lagerström, Gopinath Balakrishnan, Brandon Maltzman

Defensive Publications Series

Retrieval-augmented generation, a technique to improve the accuracy of responses of large language models (LLM), can result in an expanded attack surface for the LLM and an increased potential for exfiltration of sensitive data. This disclosure describes techniques to reduce the attack surface for LLMs that use retrieval-augmented generation. In a data upload phase, access permissions of data resources are recorded and quantified. Implicit permissions granted by the LLMs to different principals are assessed. If a data classification scheme is added to the data resources, a score can measure the risk of a prompt provided to the LLM, thus forestalling …

Computationally Efficient Hdr Video Using A Packed Video Gain Map, Na

Defensive Publications Series

Gain map is a set of techniques that provide a consistent high dynamic range (HDR) appearance of visual content across devices based on an adaptation of the content to the capabilities of the display. When gain maps are applied to video, the reconstructed video frames require two decodes, one for the base frame and another for the gain-map frame, thereby doubling processing requirements. This disclosure describes techniques that reduce the number of decodes in gain-mapped video by scaling down the resolution of the gain-map frames and by packing them together into one frame. Gain map decodes that are conventionally performed …
