A system and method executed in one or more servers that interface with a Database Management System (DBMS) for signing and exchanging documents electronically with or without a PIV. If a PIV card is used, a card reader reads embedded private biometric key stored on the card and sends the private key to a node that has the corresponding public key on the X.509 certificate. The public key is derived from the private biometric key embedded in the PIV card as described above. Information contained in X.509 certificate is used to authenticate a user for example using the SSH protocol. If a PIV card is not used, the biometric data represents captured biometric data blocks, which are used to generate a biometric hash at a subscriber node. The subscriber node sends the biometric hash to a plurality of observer nodes that validate the hash by sending validation responses based on hash ledgers states at each observer node. If most of the observer nodes validate the biometric hash, the subscriber is authenticated for signing documents under any role a subscriber may have in an organization.

The invention provides a chromosomal aneuploid and copy number variation detecting method and application thereof. Particularly, sequencing is performed on whole genomes of to-be-detected samples, and sequencing data of the samples are obtained. When a certain chromosome in an embryonic cell is a trisomy chromosome or haplochromosome, the copy rate of the chromosome is increased or decreased compared with that of a normal diploid chromosome, information analysis is performed through biostatistics, and aneuploids can be accurately detected. An experimental result shows that the chromosomal aneuploid and copy number variation can be simply, rapidly and accurately detected through the method.

The invention discloses a living tissue mode detection method, a living tissue mode detection device, a biostatistics authentication method and a biostatistics authentication device. The invention allows reliable biometric authentication without risk of forgery or the like. The invention allows biometric authentication and biometric authentication. Detects the concave-convex distribution pattern of deep skin tissue covered by epidermal tissue to extract a unique pattern of living tissue. Biometric authentication is performed based on the detected pattern. The concavo-convex distribution pattern is optically detected by utilizing the difference in optical properties between the epidermis tissue and the deep skin tissue. In this case, long-wavelength light such as near-infrared light is used as illumination light projected onto skin tissue. A branched portion of a subcutaneous blood vessel was used as a portion to be detected. The portion to be examined is determined based on the structure of the bifurcation, in which case subcutaneous blood vessels can be used for biopsy identification.
