A cluster of bacteremia episodes with Klebsiella pneumoniae was noted in patients in a hematology-oncology ward during a 3-week period. Random amplified polymorphic DNA (RAPD) analysis, a novel technique for generating chromosomal fingerprints from bacterial isolates, was used as an aid to the epidemiological investigation of this cluster. For each of the two patients from whom multiple isolate...

Latent Overlapped fingerprints are frequently encountered in latent fingerprints lifted from crime scenes. Overlapping occurs when the same location of an object is touched by one or more fingers several times. It is necessary to separate such latent overlapped fingerprints into component fingerprints so that existing fingerprint matchers can recognize them. In fact, fingerprint examiners usual...

We specify a system for authentication and key derivation using genetic fingerprints which prevents the recovery of biometric information from data stored for verification. We present a detailed security analysis based on es­ timates of the entropy of the DNA data and formal security results. The scheme is shown to be robust and efficient by analysing the typical frequency and structure of erro...

Overlapped fingerprints are frequently encountered in latent fingerprints lifted from crime scenes. It is necessary to separate such overlapped fingerprints into component fingerprints so that existing fingerprint matchers can recognize them. The most crucial step in separating overlapped fingerprints is the separation of mixed orientation fields into component orientation fields. In this paper...

With the rapid progress of generation technology, it has become necessary to attribute origin fake images. Existing works on image attribution perform multi-class classification several Generative Adversarial Network (GAN) models and obtain high accuracies. While encouraging, these are restricted model-level attribution, only capable handling images generated by seen with a specific seed, loss ...

Restriction mapping involves cleaving DNA clones at specific sites with enzymes to produce a set of fragments. These fragments have characteristic lengths which together constitute a multiset (a set allowing repeated elements) called the “fingerprint” of the clone. Clones that overlap with each other share common restriction fragments as long as the region of overlap contains at least two enzym...
