Barriers to Black-Box Constructions of Traitor Tracing Systems
two-party computation Secure Multiparty Computation
2015/12/21
Reducibility between different cryptographic primitives is a fundamental problem in modern
cryptography. As one of the primitives, traitor tracing systems help content distributors recover
the ident...
Side Ratio Constrain Based Precise Boundary Tracing Algorithm for Discrete Point Clouds
Laser Scanning (LiDAR) Edge detection Aerial Photogrammetry Feature Extraction
2015/12/8
Boundary tracing of discrete points is an important step to building model reconstruction using LiDAR data, its result directly effects the location regularization of building corners and the reconstr...

The error of the height estimates are precisely quantified by comparison with the 3D model height. This paper discusses the development and testing of the inversion of tree height from simulations of ...
A traitor tracing system enables a publisher to trace a pirate decryption box to one of the secret keys used to create the box. We present the first traitor tracing system where ciphertext size is "co...
Multiparty Key Exchange, Efficient Traitor Tracing, and More from Indistinguishability Obfuscation
Multiparty Key Exchange Effi cient Traitor Tracing
2015/8/5
Our traitor tracing system is fully collusion resistant with short ciphertexts, secret keys,
and public key. Ciphertext size is logarithmic in the number of users and secret key size is
independent ...
A Novel Optical Encoding Scheme for Network Node Tracing in All-Optical Reconfigurable Wavelength Routing Networks
Optical Encoding Scheme Network Node All-Optical Reconfigurable Wavelength Routing Networks
2009/7/17
An optical prime-number-encoded tag is employed as distinct network node identifier so as to realize network node tracing in reconfigurable wavelength routing networks, via prime number multiplication...
The contact and immersion ultrasound methods compared using the ray tracing method
biometry ultrasound measurement immersion and contact method ray tracing
2009/7/14
The goal of this article was to compare the contact and immersion ultrasound methods using
simulated data. The pursued changes were interrelated with both the axial length of the eye and
with partia...
Skew ray tracing and error analysis of optical elements with ellipsoid boundary surfaces
skew ray tracing error analysis
2008/4/6
Utilizing a ray tracing approach based upon Snell’s optical laws and a 4×4 homogeneous coordinate transformation matrix, this study conducts a systematic analysis of the errors induced in the paths of...
