Honor and Destruction: The Conflicted Object in Moral Rights Law

In 1990, the Copyright Act was amended to name visual artists, alone among protected authors, possessors of moral rights, a set of non-economic intellectual property rights originating in nineteenth-century Europe. Although enhancing authors\u27 rights in a user-oriented system was a novel undertaking, it was rendered further anomalous by the statute\u27s designated class, given copyright\u27s longstanding alliance with text. And although moral rights epitomize the legacy of the Romantic author as a cultural trope embedded in the law, American culture offered little to support or explain the apparent privileging of visual artists over other authors. What, if not a legal or cultural disposition toward visual artists, precipitated the enactment of a moral rights statute like the Visual Artists Rights Act of 1990 (\u27\u27VARA )? This Article demonstrates that the answer is less related to authorship concerns than would reasonably be surmised from a doctrine premised on the theory that a creative work embodies the author\u27s honor, personhood, and even soul

Alpha Channel Fragile Watermarking for Color Image Integrity Protection

This paper presents a fragile watermarking algorithm`m for the protection of the integrity of color images with alpha channel. The system is able to identify modified areas with very high probability, even with small color or transparency changes. The main characteristic of the algorithm is the embedding of the watermark by modifying the alpha channel, leaving the color channels untouched and introducing a very small error with respect to the host image. As a consequence, the resulting watermarked images have a very high peak signal-to-noise ratio. The security of the algorithm is based on a secret key defining the embedding space in which the watermark is inserted by means of the Karhunen–Loève transform (KLT) and a genetic algorithm (GA). Its high sensitivity to modifications is shown, proving the security of the whole system

Digital Image Access & Retrieval

The 33th Annual Clinic on Library Applications of Data Processing, held at the University of Illinois at Urbana-Champaign in March of 1996, addressed the theme of "Digital Image Access & Retrieval." The papers from this conference cover a wide range of topics concerning digital imaging technology for visual resource collections. Papers covered three general areas: (1) systems, planning, and implementation; (2) automatic and semi-automatic indexing; and (3) preservation with the bulk of the conference focusing on indexing and retrieval.published or submitted for publicatio
