Abstract

The invention relates to a computerized method for compressing genome sequencing data. The method comprises the following steps: comparing the genome sequencing data with reference sequencing data; obtaining one or more differential read sequences, each of the one or more differential read sequences being a read sequence of the genomic sequencing data that is different from a corresponding read sequence of the reference sequencing data; and obtaining compressed genomic sequencing data by compressing the one or more difference segment sequences using a statistical compression method or using an assembly method with a probabilistic data structure. In some embodiments, the method also has the step of assembling the plurality of reads to form reference data. In some embodiments, the method also has the step of storing the compressed genomic data in the blockchain.
