Abstract

The present disclosure proposes a method for checking integrity of an Al model using distributed ledger technology (DLT) and a system thereof. The proposed method leverages the state-of-the-art watermarking mechanism and ties it up with DLT to generate proof of origin (provenance) in a tamper-proof way. The Al model is registered on the distributed ledger (DL) by uploading full checksum, selective checksums, watermark data and at least the predefined output of the watermark data, a unique model ID is received upon registration. The ownership and integrity of Al model is then determined by matching the model and the output of the watermark data followed by verification of the full and selective checksum of the Al model.

The invention relates to a micromechanical pressure sensor element as well as a pressure sensor system comprising such a pressure sensor element. The pressure sensor element establishes an electric contact in the event of a specified first pressure being applied. For this purpose, the pressure sensor element has a membrane which can be moved or deflected by an applied pressure. A first cavity into which the membrane can be deflected is provided below the membrane. The invention is characterized in that two contact elements are provided which come into contact with each other, in particular via a mechanical contact, on the basis of a first applied pressure being exceeded so that an electric contact is established. At least one first contact element, which is directly or indirectly connected to the membrane, and a second contact element, which is directly or indirectly connected to the cavity base, are provided.
