Abstract: In various embodiments, systems and methods for generating attested video image data are provided. In some embodiments, an ISP pipeline incorporates a secure cryptographic signing mechanism to digitally sign content-based outputs in a way that attests to the authenticity of the process by which the content was processed before output from the camera. The ISP pipeline may include a hardware security module that inputs video image data from an image sensor, and generates an attestation package that includes attestations about the video content, in combination with an attestation of how it was produced, and signs those attestations together using a key to produce an output comprising attested media data. The ISP pipeline may apply supplemental attestations to the attestation package representing facts associated with the video content that evidence the authenticity. The digital signature applied to the attestation package may use a zero-knowledge proof to describe the signing key.

Abstract: Methods and systems described herein involve using long cell-free DNA fragments to analyze a biological sample from a pregnant subject. The status of methylated CpG sites and single nucleotide polymorphisms (SNPs) is often used to analyze DNA fragments of a biological sample. A CpG site and a SNP are typically separated from the nearest CpG site or SNP by hundreds or thousands of base pairs. Finding two or more consecutive CpG sites or SNPs on most cell-free DNA fragments is improbable or impossible. Cell-free DNA fragments longer than 600 bp may include multiple CpG sites and/or SNPs. The presence of multiple CpG sites and/or SNPs on long cell-free DNA fragments may allow for analysis than with short cell-free DNA fragments alone. The long cell-free DNA fragments can be used to identify a tissue of origin and/or to provide information on a fetus in a pregnant female.

Abstract: Methods and systems are described herein that include using multiplexed digital amplification reactions to measure the sizes of a plurality of nucleic acid molecules. In various embodiments, the digital amplification reactions use multiple pairs of separate forward and reverse primer pairs to amplify targeted regions of the nucleic acid molecules, where the targeted regions are separated by a specified number of base pairs.

The methods and systems are particularly useful for determining the size distributions of the nucleic acid molecules, or classifying a pathology of a subject from whom the nucleic acid molecules are sampled. Advantageously, the methods and systems can measure the sizes of long nucleic acid molecules without relying on inefficient amplification of very long amplicons.
