Abstract: Systems and methods for analyzing genomic information can include obtaining a sequence read including genetic information; identifying, within a graph representing a reference genome, a plurality of candidate mapping positions that relate to the genetic information, the graph comprising nodes representing genetic sequences and edges connecting pairs of nodes; determining, by means of a computer system, whether an alignment with the graph surrounding each of the plurality of candidate mapping positions is advanced or basic; and performing for each candidate mapping position, by means of the computer system, a local alignment based on whether the local alignment is advanced or basic. The advanced local alignment can include a first-local-alignment algorithm, and the basic local alignment includes a second-local-alignment algorithm. Based on the local alignments, the mapped position of the sequence read can be identified within the genome.

Abstract: Systems and methods for protecting information stored in private references that are available to be queried—e.g., graph-based sequence references that users query through an interface, providing short reads to obtain the results of an alignment against the reference sequence—analyze the query and/or alignment results to determine whether the query represents an attack. The analysis may be performed before returning results to a user, and in some cases before performing the alignment.

Abstract: Embodiments of the invention protect information stored in graph-based sequence references by “watermarking” the graph with uniquely identifiable information. The watermark identifies the graph or version thereof in a detectable but nonintrusive manner. In one embodiment, insertions and/or deletions are introduced into regions of the graph.
