Authenticating digital images is increasingly becoming important because digital images
carry important information and due to their use in different areas such as courts of law as …

One of the principal problems in image forensics is determining if a particular image is
authentic or not. This can be a crucial task when images are used as basic evidence to …

The computational workload is one of the key challenges in biometric identification systems.
The naïve retrieval method based on an exhaustive search becomes impractical with the …

This paper proposes a new hash-based indexing method to speed up fingerprint
identification in large databases. A Locality-Sensitive Hashing (LSH) scheme has been …

This paper presents VENICE, a new soft vector processor (SVP) for FPGA applications.
VENICE differs from previous SVPs in that it was designed for maximum throughput with a …

Cancelable biometric schemes have been widely studied to protect templates in biometric
authentication over networks. These schemes transform biometric features and perform …

Copy-move is one of the simple and effective operations to create digital image forgeries
due to the gradually evolved image processing tools. In recent years, SIFT-based approach …

Most current fingerprint indexing systems are based on minutiae-only local structures and
index local features directly. For minutiae local structure, missing and spurious neighboring …

Fingerprint indexing plays a key role in the automatic fingerprint identification systems
(AFISs) which allows us to speed up the search in large databases without missing …

This paper describes a new fingerprint indexing approach based on vector and scalar
features, obtained from ridge-line orientations and frequencies. A carefully designed set of …
