The determination of an identity from noisy biometric measurements is a continuing
challenge. In many applications, such as identity‐based encryption, the identity needs to be …

In this paper, we propose an invertible authentication watermarking algorithm which can
detect block-wise malicious manipulations in biometric images. Our method uses an …

We present algorithms to reliably generate biometric identifiers from a user's biometric
image which in turn is used for identity verification possibly in conjunction with cryptographic …

Because making digital images secure runs into the substantial challenge of owner
authentication, many security schemes based on cryptography, steganography and …

Digital watermarking is a process by which we can embed the message in security key as
watermark to provide copyright protection to various text, image, audio and video …

We propose a robust technique for watermarking relational databases using voice as a
biometric identifier of ownership. The choice of voice as the distinguishing factor is …

In the present digital era, the number of ways to misuse multimedia data increases day by
day. The availability of high image editing tools can change the image so it becomes …

In cancelable biometrics, a template undergoes a random-like transformation process such
that it is disposable and a new template for the same identity can be re-generated for new …

In recent literature, privacy protection technologies for biometric templates were proposed.
Among these is the so-called helper-data system (HDS) based on reliable component …

With the wide spread utilization of biometric identification systems, establishing the
authenticity of biometric data itself has emerged as an important research issue. We present …
