Fingerprint Watermarking with Tamper Detection [PDF]

open access: yes, 2006
This paper proposes a watermarking method to embed watermark data into fingerprint images, without corrupting their features. The method does not require original fingerprint image to be able to detect tamper and thus authenticate the image.

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

open access: yesAdvanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Tamper detection, localization and self-recovery using slant transform with DNA encoding for medical images

open access: yesResults in Engineering
This work proposes an improved self-embedding semi-fragile watermarking scheme for a smart healthcare system using telemedicine. The watermark is produced by encoding the Slant Transform (ST) coefficients of each block of the host image.

Detecting multiple copies in tampered images [PDF]

open access: yes2010 IEEE International Conference on Image Processing, 2010
Copy-move forgeries are parts of the image that are duplicated elsewhere into the same image, often after being modified by geometrical transformations. In this paper we present a method to detect these image alterations, using a SIFT-based approach. First we describe a state of the art SIFT-point matching method, which inspired our algorithm, then we ...

Tamper detection for ubiquitous RFID-enabled supply chain

open access: yes, 2005
Security and privacy are two primary concerns in RFID adoption. In this paper we focus on security issues in general and data tampering in particular. Here we present a conceptual framework to detect and identify data tampering in RFID tags.

Deep Learning Inverse Design of Phase‐Change Reconfigurable Terahertz Metadevices for Multidimensional Secure Communication

open access: yesAdvanced Materials, EarlyView.
A deep learning inverse‐design framework is established to create versatile reconfigurable terahertz metadevices. By synergizing deep learning with phase‐change materials, this approach enables on‐demand customization of multidimensional electromagnetic responses.

Scalable Task Planning via Large Language Models and Structured World Representations

open access: yesAdvanced Robotics Research, EarlyView.
This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...
