Eigenplaces: Segmenting Space through Digital Signatures

Digital signatures

Defining Digital Space Through a Visual Language

approach of design at first glance. But there is just as in design the possibility to deal with larger constructs abstractly.. Programming is a way of interfacing the medium in its own language. The programming languages are two way communication devices that allow the description of processes in human and machine readable terms. Programming is capable of describing process and structures that ...

Segmenting Actions in Velocity Curve Space

Reliable segmentation of actions performed by objects, is critical to the understanding of semantic content in a video. Deciding which portion of object motion sequence is a distinct action unit, however, is often d@@ult, even for humans. We seem to hierarchically compose actions By noting characteristic changes in the nature of motion. This paper present an action segmentation algorithm that m...

Matrix Signatures: From MACs to Digital Signatures

We present the first general implementation to provide the properties of digital signature using MACs in a system consisting of any number of untrusted clients and n servers, up to f of which are Byzantine. At the heart of the implementation is a novel matrix signature that captures the collective knowledge of the servers about the authenticity of a message. Matrix signatures can be generated o...

Digital Signatures for Automobiles?!

Identifying and tracking vehicles is of major importance for today’s logistics. The common non-electronic solutions are both easy to forge and difficult to use over distances. Combining the successful technologies of digital signatures and the Global Positioning System allows the secure identification of any car and checking its location. Both types of information can improve the fleet manageme...
