Abstract
Data is captured by a data capture apparatus in a manner to ensure authenticity of the data to the data capture apparatus. Transducer signaling is generated in response to physical excitation of one or more transducers, and is digitized to produce digital signaling. A cryptographic key is stored in association with the data capture apparatus. At least portions of the digital signaling are digitally signed based on the cryptographic key to produce an authenticatable set of captured data. A security boundary is provided within which the digitizing, storing, and digitally signing are performed. Production of the authenticatable set of captured data is prevented in response to a breach of the security boundary.
