We present an analysis of a new technique for the authentication of ID cardholders, based
on the integration of a biometrics-based authentication system with digital watermarks. The …

We present a new integrity watermark based on hologram techniques for document
authentication. We focus on ID-Card watermarks. The main goal is to illustrate the use of …

One major application domain for digital watermarks is copyright protection. Besides the
design of watermarking algorithms, technologies for copyright holder identification have to …

In this paper we analyze chances and challenges with respect to the security of using
biometrics in ID documents. We identify goals for ID documents, set by national and …

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 …

Identity documents, such as ID cards, passports, and driver's licenses, contain textual
information, a portrait of the legitimate holder, and eventually some other biometric …

Problem of fake image in ID card spreads all over the world eg false Thai national ID card in
Thailand. This problem is quite difficult to detect because appearances of human face …

Authentication of digital documents is an important concern as digital documents are
replacing the traditional paper-based documents for offcial and legal purposes. This is …

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

Digital documents play a major role in modern era. They are easy to generate, modify and
manage. The easy modifiable property of digital document makes it more vulnerable to …
