This paper presents a new method for robust data hiding in curves and highlights potential applications including digital fingerprinting of map document for trace and track purposes. We parameterize a curve using the B-spline model and add a spread spectrum sequence to the coordinates of the B-spline control points. In order to achieve robust fingerprint detection, we propose an iterative align...

Location fingerprinting is a widely used technique for indoor localization. Traditional fingerprinting methods are generally in point-type, where the received signal strength indicators (RSSI) at discrete points are trained in the offline phase and used as reference in the online phase. This type of radio map requires many human efforts to calibrate and does not take into account the spatial re...

Protecting sensitive information from unauthorized disclosure is a major concern of every organization. As an organization’s employees need to access such information in order to carry out their daily work, data leakage detection is both an essential and challenging task. Whether caused by malicious intent or an inadvertent mistake, data loss can result in significant damage to the organization...

We extend the concept of two-level fingerprinting codes, introduced by Anthapadmanabhan and Barg (2009) in context of traceability (TA) codes [1], to other types of fingerprinting codes, namely identifiable parent property (IPP) codes, secure-frameproof (SFP) codes, and frameproof (FP) codes. We define and propose the first explicit non-trivial construction for two-level IPP, SFP and FP codes.

An audio fingerprint is a compact digest derived from perceptually relevant aspects of a recording. Fingerprinting technologies allow the monitoring of audio content without the need of meta-data or watermark embedding. However, additional uses exist for audio fingerprinting and some are reviewed in this article.

Total DNA of Streptococcus uberis from cows with mastitis was analyzed by DNA amplification fingerprinting (DAF) and compared with restriction endonuclease fingerprinting (REF). DAF grouped 22 strains into 15 distinct patterns, while REF grouped them into 12 patterns. These results suggest that DAF is a useful technique for subtyping strains of S. uberis.

Separating codes, initially introduced to test automaton, have revived lately in the study of fingerprinting codes, which are used for copyright protection. Separating codes play their role in making the fingerprinting scheme secure agains coalitions of pirates. We provide here better bounds, constructions and generalizations for these codes.

Title of dissertation: RANDOM CODES AND GRAPHS FOR SECURE COMMUNICATION Nagaraj Prasanth Anthapadmanabhan Doctor of Philosophy, 2009 Dissertation directed by: Professor Alexander Barg Department of Electrical and Computer Engineering This dissertation considers two groups of problems related to secure communication. The first line of research is devoted to theoretical problems of copyright prot...

The rapid expansion of smartphones’ market coupled with the advances in mobile computing technology has opened up doors for new mobile services and applications. Quite a few of these services require the knowledge of the exact location of their handsets. Although, existing global positioning systems (GPS) perform best in outdoor environments, they have poor performance indoors. This has initiat...

Repetitive sequence-based polymerase chain reaction fingerprinting was used to characterize 23 vancomycin-nonsusceptible enterococcal isolates from 2003 to 2004. Five genetically related clusters spanned geographically distinct referring centers. DNA fingerprinting showed infant-to-infant transmission from referring institutions. Thus, community healthcare facilities are a source of vancomycin-...
