In this work an efficient format-compliant encryption approach for regular languages is proposed, block-based cycle-walking. The approach can transparently trade-off security for efficiency and can be adjusted to the desired level of security. The relationship between the encryption of regular languages and the encryption of JPEG2000 bitstreams is established. Block-based cycle-walking for the ...

Future system development and management efforts must strive to institutionalize these gains and provide ongoing, incremental improvement in these areas. With the growth of e-commerce and further socioeconomic reliance on IT, the organizations that have achieved these gains will be well positioned to outdistance those who were less aggressive. Figure 1 depicts the silver linings and competitive...

Lantern Field is a communal, site-specific installation that takes shape as a spatially responsive audio-visual field. The public participates in the creation of the installation, resulting in shared ownership of the work between both the artists and participants. Furthermore, the installation takes new shape in each realization, both to incorporate the constraints and affordances of each speci...

A great deal of computation for JPEG2000 encoding is a redundancy when the compression rate is high. That is because many coded bit-streams will be truncated after the rate control of JPEG2000. In this paper, an effective scheme for JPEG2000 rate control is proposed. Through this scheme, the computation complexity for JPEG2000 entropy coding, that is, EBCOT Tier-I, can be greatly reduced almost...

Along with the spread of social media, it has become possible to extract events occurring in the real world in real time. A benefit of analysis using data with position information is that it can accurately extract an event from a target area to be analyzed. However, because social media data include few data with location information, the amount to analyze is insufficient for almost all areas:...

Navigation through large microscopical images is a potential benefit for histology or pathology teaching, quality of diagnosis in pathology or communication between pathologists in some telemedicine applications. However, the size of this kind of images is prohibitive for navigation with conventional techniques. This paper presents a system which constructs large microscopical images and descri...
