A New Phase Unwrapping Algorithm Based On Three Wavelength Phase Shift Profilometry Method, Limei Song, Xiaoxiao Dong, Jiangtao Xi, Yanguang Yu, Chaokui Yang

Dr Yanguang Yu

Phase Shift Profilometry (PSP) method is widely used in 3D shape measurement. The advantage of the PSP method is that it is less sensitive to the surface reflectivity variations and the object can be measured point by point. But if only a single wavelength λ₁ is used, the step height cannot be larger than λ₁/4. In order to measure step height object, Gray Code (GC) and Multi-Wavelength Phase Shift Profilometry (MWPSP) method are used. But the GC method cannot solve the problem of the objects with a variety of colors under different illumination. The shortcoming of MWPSP …

Partially Overlapped Range Images Registration Based On Fringe Pattern Profilometry, Xiaochen He, Jiangtao Xi, Yanguang Yu

Dr Yanguang Yu

Registration of two three-dimensional (3-D) point sets is a fundamental problem of 3-D shape measurement and modeling pipeline. This paper investigates the automatic pair-wise method to register partially overlapped range images generated by self-developed fringe pattern profilometry (FPP) system. The method is based on the classic iterative closest point (ICP) algorithm but combined with several extensions to adapt to the experimental data. Firstly, the distance function for correspondence finding is modified to be the weighted linear combination of positions and Euclidean invariant features for improving the probability of convergence. In addition, outliers can be discarded through robust statistics and adaptive …

Fast Quality-Guided Phase Unwrapping Algorithm For 3d Profilometry Based On Object Image Edge Detection, Ke Chen, Jiangtao Xi, Yanguang Yu

Dr Yanguang Yu

A main challenge associated with 3-dimentional fringe pattern profilometry (3D-FPP) systems is the unwrapping of phase maps resulted from complex object surface shapes with both robustness and speed guaranteed. In this paper we propose a new quality-guided phase unwrapping algorithm. In contrast to the conventional quality-guided methods, we classify pixels on wrapped phase map into two types by detecting edge pixels on object image: high quality (HQ) pixels corresponding to smooth phase changes and low quality (LQ) ones to rough phase changes. In order to improve the computational efficiency, these two types of pixels are unwrapped by means of different …

Towards Qos-Based Web Services Discovery, Jun Yan, Jingtai Piao

Dr Jun Yan

The current UDDI-based web services discovery technologies are designed to discover services which can satisfy consumers’ functional requirements. The consumers’ non-functional requirements such as quality of services are largely ignored in discovery. This may lead to the problem that the services returned from discovery are ineffective and even useless. To solve this problem, this paper presents an approach to achieving QoS-based Web services discovery. Data structures are proposed for both service providers and service consumers to describe non-functional information about services. A serial of algorithms are developed for matching and ranking services according to consumers’ non-functional requirements.

A Generic Construction Of Dynamic Single Sign-On With Strong Security, Jinguang Han, Yi Mu, Willy Susilo, Jun Yan

Dr Jun Yan

Single Sign-On (SSO) is a core component in a federated identity management (FIM). Dynamic Single Sign-on (DSSO) is a more flexible SSO where users can change their service requirements dynamically. However, the security in the current SSO and DSSO systems remain questionable. As an example, personal credentials could be illegally used to allow illegal users to access the services. It is indeed a challenging task to achieve strong security in SSO and DSSO. In this paper, we propose a generic construction of DSSO with strong security. We propose the formal definitions and security models for SSO and DSSO, which enable …

Insc: An Iterative Negotiation Approach For Service Compositions, Q He, Yun Yang, Jun Yan, Hai Jin

Dr Jun Yan

The service-oriented paradigm offers support for engineering service-based systems (SBSs) based on service compositions. The selection of services with the aim to fulfil the quality constraints for SBSs and to achieve the optimisation goals is a critical and challenging issue. In particular, when the quality-of-service (QoS) constraints for a SBS are severe, it is often difficult to find an optimal solution for the SBS. Exploiting the competition among service providers can help SBS developers obtain favourable QoS offers for the component services of SBSs and increase the possibility of finding optimal solutions for the SBSs. In this paper, we present …

Privacy-Preserving Decentralized Key-Policy Attribute-Based Encryption, Jinguang Han, Willy Susilo, Yi Mu, Jun Yan

Dr Jun Yan

Decentralized attribute-based encryption (ABE) is a variant of a multiauthority ABE scheme where each authority can issue secret keys to the user independently without any cooperation and a central authority. This is in contrast to the previous constructions, where multiple authorities must be online and setup the system interactively, which is impractical. Hence, it is clear that a decentralized ABE scheme eliminates the heavy communication cost and the need for collaborative computation in the setup stage. Furthermore, every authority can join or leave the system freely without the necessity of reinitializing the system. In contemporary multiauthority ABE schemes, a user's …

Improved Certificateless Signature Scheme Provably Secure In The Standard Model, Yong Yu, Yi Mu, Guilin Wang, Q Xia, B Yang

Dr Guilin Wang

Certificateless cryptography shares many features of identity-based cryptography and partially solves the problem of key escrow. Three certificateless signature schemes without random oracles were found in the literature. However, all the schemes suffer from some common drawbacks. First, by obtaining a signature on a message and replacing the public key of a signer, an adversary can forge valid signatures on the same message under the replaced public key. Secondly, all the schemes require a relatively large size of public parameters. The authors propose a new certificateless signature scheme, which exhibits an improvement on the existing schemes. Compared with the previous …

Provably Secure Single Sign-On Scheme In Distributed Systems And Networks, Jiangshan Yu, Guilin Wang, Yi Mu

Dr Guilin Wang

Distributed systems and networks have been adopted by telecommunications, remote educations, businesses, armies and governments. A widely applied technique for distributed systems and networks is the single sign-on (SSO) which enables a user to use a unitary secure credential (or token) to access multiple computers and systems where he/she has access permissions. However, most existing SSO schemes have not been formally proved to satisfy credential privacy and soundness of credential based authentication. To overcome this drawback, we formalise the security model of single sign-on scheme with authenticated key exchange. Specially, we point out the difference between soundness and credential privacy, …

On The Invisibility Of Designated Confirmer Signatures, Fubiao Xia, Guilin Wang, Rui Xue

Dr Guilin Wang

As an important cryptographic primitive, designated con- rmer signatures are introduced to control the public veria- bility of signatures. That is, only the signer or a semi-trusted party, called designated conrmer, can interactively assist a verier to check the validity of a designated conrmer sig- nature. The central security property of a designated con- rmer signature scheme is called invisibility, which requires that even an adaptive adversary cannot determine the valid- ity of an alleged signature without direct cooperation from either the signer or the designated conrmer. However, in the literature researchers have proposed two other related properties, called impersonation …

A Pairing-Free Id-Based One-Pass Authenticated Key Establishment Protocol For Wireless Sensor Networks, Rehana Yasmin, Eike Ritter, Guilin Wang

Dr Guilin Wang

Due to resource constraints and unique features of wireless sensor networks (WSNs), designing a key establishment protocol is much harder for WSNs than for traditional wired and wireless counterparts. In this paper, we propose a new efficient and secure ID-based one-pass authenticated key establishment protocol between an outside user and a sensor node. The proposed protocol does not require sensor nodes to compute any expensive pairing function. Moreover, it imposes very light computational and communication overheads and also provides scalability. We analyze security and efficiency of the proposed protocol by comparing firstly the session key establishment protocols for WSNs and …

Incorporation Of Radius-Info Can Be Simple With Simplemkl, Xinwang Liu, Lei Wang, Jianping Yin, Lingqiao Liu

Dr Lei Wang

Recent research has shown the beneﬁt of incorporating the radius of the Minimal Enclosing Ball (MEB) of training data into Multiple Kernel Learning (MKL). However, straightforwardly incorporating this radius leads to complex learning structure and considerably increased computation. Moreover, the notorious sensitivity of this radius to outliers can adversely affect MKL. In this paper, instead of directly incorporating the radius of MEB, we incorporate its close relative, the trace of data scattering matrix, to avoid the above problems. By analyzing the characteristics of the resulting optimization, we show that the beneﬁt of incorporating the radius of MEB can be fully …
