In fingerprinting, a signature, unique to each user, is embedded in each distributed copy of a multimedia content, in order to identify potential illegal redistributors. This paper investigates digital fingerprinting problems involving millions of users and a handful of colluders. In such problems the rate of the fingerprinting code is often well below fingerprinting capacity, and the use of co...

Keywords: Co-utility Multicast fingerprinting Anonymous fingerprinting Game theory a b s t r a c t In conventional multicast transmission, one sender sends the same content to a set of receivers. This precludes fingerprinting the copy obtained by each receiver (in view of redistribution control and other applications). A straightforward alternative is for the sender to separately fingerprint an...

Digital fingerprinting of multimedia data involves embedding information in the content signal and offers protection to the digital rights of the content by allowing illegitimate usage of the content to be identified by authorized parties. One potential threat to fingerprinting is collusion, whereby a group of adversaries combine their individual copies in an attempt to remove the underlying fi...

As the markets of digital contents over computer networks become more popular, illegal redistribution of contents by a buyer becomes the more serious problem. To deter illegal redistribution, various fingerprinting schemes have been proposed. The fingerprinting schemes enable merchants to embed information which identifies the original buyer to the purchased content. Identifying the original bu...

Advertisers are increasingly turning to fingerprinting techniques to track users across the web. As web browsing activity shifts to mobile platforms, traditional browser fingerprinting techniques become less effective; however, device fingerprinting using built-in sensors offers a new avenue for attack. We study the feasibility of using motion sensors to perform device fingerprinting at scale, ...

background and objectives: traditional polyherbal oils are still in use in persian traditional medicine (ptm). most of these formulations are prepared via traditional procedures such as maceration of herbs in oils or evaporating aqueous herbal extracts in boiling or heating oils as the vehicle. thus, their quality control, standardization and authentication are real challenges due to the lack o...

Coding methods for fingerprinting digital information are considered, with the aim of deterring users from copyright violation. A general model for discrete fingerprinting is presented, along with a simple embedding method for text documents. Different types of attacks are discussed, including attacks from colluding pirates. Some preliminary results are derived for random fingerprinting codes. ...

Global control of tuberculosis is increasingly dependent on rapid and accurate genetic typing of Mycobacteriumtuberculosis. Spoligotyping is a first-line genotypic fingerprinting method for M.tuberculosis isolates. An international online database (SpolDB4) of spoligotype patterns has been established wherein a clustered pattern (shared by ≥2 isolates) is designated a shared international type ...

Fingerprinting protocol applies a watermarking technique to embed a fingerprinting information in a digital content such as music, image, movie, etc.. The cryptographic protocol is studied by many researchers, but how to apply watermarking techniques is not remarked. In this paper, we study the problem to implement the watermarking techniques in the fingerprinting protocol, and then propose an ...
