Counterpublic and counterprivate: Zoe Leonard,David Wojnarowicz,and the political aesthetics of intimacy

In this paper we explore the space that dyadic intimacy plays within the counterpublic world-building of political activism. We reflect on a particular encounter between the artists and ACT UP activists Zoe Leonard and David Wojnarowicz by offering two readings of what we call the “counterprivate” relation between the two. In the first part of our argument, we contend that the counterprivate couple form (found in our case study of Leonard and Wojnarowicz) occasions a space of provisional leave from the normative affective, aesthetic, and identity-based impulses which tend to emerge in social movement group formation. Despite established critiques of the private, dyadic intimacy of the couple within social movement theory and queer and feminist cultural studies, we highlight the value of counterprivate couples – not in place of the collective world-building that is made possible by political organizing and collective identity, but as a necessary aesthetic complement to collective, participatory politics. In the second part of our argument, we read the intimacy between Leonard and Wojnarowicz as a private moment of expressed doubt that has subsequently been institutionalized into a public discourse through the context of art. Here the counterprivate couple form in turn becomes a counterpublic mode of collective world-making once more. This transformation from counterprivate relation to public discourse occasions a practice of collective subject formation (in the institutional terrain of art) that affirms doubt, curiosity, and poetic beauty as part of the reproductive labor involved in political participation.     

Enhancing security of fingerprints through contextual biometric watermarking

This paper presents a novel digital watermarking technique using face and demographic text data as multiple watermarks for verifying the chain of custody and protecting the integrity of a fingerprint image. The watermarks are embedded in selected texture regions of a fingerprint image using discrete wavelet transform. Experimental results show that modifications in these locations are visually imperceptible and maintain the minutiae details. The integrity of the fingerprint image is verified through the high matching scores obtained from an automatic fingerprint identification system. There is also a high degree of visual correlation between the embedded images, and the extracted images from the watermarked fingerprint. The degree of similarity is computed using pixel-based metrics and human visual system metrics. The results also show that the proposed watermarked fingerprint and the extracted images are resilient to common attacks such as compression, filtering, and noise.
