Protection of intellectual property in digital contents has been a subject of research for many years and led to the development of various techniques. Digital fingerprinting scheme is an important class of these techniques. The goal of fingerprinting scheme is to deter people from illegally redistributing digital data. But, the problem of known anonymous fingerprinting schemes is that, being based on computationally unspecified black boxes: secure multiparty computation or minimum disclosure proofs of knowledge. Their complexity is much too high to be implemental in real application. Still less, buyer's memory and computation power is very small in mobile communication. We present an anonymous fingerprinting scheme for mobile communication using mobile agent, which is efficient and feasible from a practical view. The basic primitive used is a proxy certificates. Our proposal satisfies that (1) only the buyer can know the fingerprinted copy however the mobile agent executes its computations instead of him/her, and (2) it reduces amount of the buyer's computations to the minimum and risk about exposure of the buyer's private information which will be occurred owing to delegation.

The proposed method takes advantage of spectral information content in the hyperspectral images, EO-1 hyperion, to find road candidates. The assumption of this approach assumes that each pixel in the hyperspectral images is composed of a linear mixing of the reflectance from various components of the Earth's surface. The algorithm derived from the statistical and linear model is used to highlight the targets - road features and to suppress the background features of a scene. After road detection, all potential road candidates have been presented in the detected image. The objective is to avoid predicting uncertain road points and setting complex criteria to form the road network. Finally, the detected road segments will be traced and connected to generate skeletonized results. This proposed approach could be used to detect other linear features, such as a drainage network, from the hyperspectral imagery as well. In this way, the vectorized image could be produced to provide additional thematic layers for further spatial analysis in GIS applications.

Database systems have become the most crucial constructing components of data stores underlying modern application systems. Popular role-based access control model by Sandhu R.S. and E.J. Coyne proposed a way to manage users' access rights. However, employees playing several roles sometimes acquire access rights above their duties. These employees, for their own benefits, are capable of accessing data illegally, modifying or inserting data temporary then illegally outputting data, and finally changing data back to their original status that satisfy integrity of database contents. Usually databases are updated through record overwriting or deleting and are difficult to trace each user transaction. Hence, owners of these database systems, potentially, might become victims of data temporary misuse by criminals. Ooi, Goh, and Tan proposed a dimension space transformation concept based on indexing bitemporal databases1998, which states the concept of transforming one-dimensional time domain to two-dimensional x-y coordinates. We first study state-of-the-art of access control methods, then address role conflicts in access rights, and finally discuss the Bitemporal relation with valid and process time attributes. We further propose an approach, recording database usage trails and transparent to general users, to accomplish all record queries and changes, including insertion, deletion, modification, and retrieving, referenced Ooi, Goh, and Tan's work. Hopefully, this approach might facilitate achieving forensic objects of database traceability and accountability.
数据库系统已成为现代应用系统中最重要的数据存储构件。流行的基于角色的访问控制模型Sandhu R.S.和E.J. Coyne提出了一种管理用户访问权限的方法。然而，扮演多个角色的员工有时会获得超出其职责的访问权。这些员工为了自己的利益，可以非法访问数据，临时修改或插入数据，然后非法输出数据，最后将数据更改回满足数据库内容完整性的原始状态。通常数据库是通过覆盖或删除记录来更新的，很难跟踪每个用户事务。因此，这些数据库系统的所有者可能会成为犯罪分子临时滥用数据的受害者。Ooi, Goh, and Tan提出了一种基于索引双时数据库的维度空间转换概念(1998)，该概念陈述了将一维时域转换为二维x-y坐标的概念。本文首先研究了访问控制方法的最新进展，然后讨论了访问权限中的角色冲突，最后讨论了有效时间属性和进程时间属性之间的双时间关系。我们进一步提出了一种方法，记录数据库使用轨迹并对一般用户透明，以完成所有记录的查询和更改，包括插入，删除，修改和检索，参考了Ooi, Goh和Tan的工作。希望这种方法能够促进实现数据库可跟踪性和问责制的取证对象。

Malicious executables are computer programs, which may cause damages or inconveniences for computer users when they are executed. Virus is one of the major kinds of malicious programs, which attach themselves to others and usually get executed before the host programs. They can be easily planted into computer systems by hackers, or simply down loaded and executed by naive users while they are browsing the Web or reading e-mails. They often damage its host computer system, such as destroying data and spoiling system software when they are executed. Thus, to detect computer viruses before they get executed is a very important issue. Current detection methods are mainly based on pattern scanning algorithms. However, they are unable to detect unknown viruses. An automatic heuristic method to detect unknown computer virus based on data mining techniques, namely decision tree and naive Bayesian network algorithms, is proposed and experiments are carried to evaluate the effectiveness the proposed approach.

We introduce a human surveillance system, which integrated technologies of face tracking, face detection, and face recognition to authenticate personal identity in real time. The system located all of the faces in the view quickly and tracked them all the time even though people crossed. Facial features of a selected target were estimated, and the personal identity was justified. In our designation, spatial and temporal information over a number of continuous frames were accumulated and combined to make the system more stable and robust to unexpected human activities. More than 60 persons of an experiment were trained and recognized in the natural environment. Each of them was effectively authenticated by the system in terms of recognition accuracy and performance.

As the rapid progressing of mobile communication systems, personal communication systems have been brought new problems on the security aspects by the new communication technologies. Public-key cryptography technologies offer solutions to many of the existing security problems in communication system. The RSA algorithm is the most popular public-key cryptosystem. We consider how to effectively implement the RSA algorithm on assembler of Texas Instruments TMS320C55x family. Many wireless and mobile devices include the TMS320C55x chip. We propose an efficient method to implement modular exponentiation operation based on TMS320C55x. By the experiments, our implementation method can perform about 6 times of 1024 bits RSA encryption/decryption operations in one second.

In the past several years, there has been an explosive growth in digital imaging technology and applications. Since digital images and video are now widely distributed via the Internet and various public channels, there is an urgent need for copyright protection against unauthorized data reproduction. Digital watermarking is an effective and popular technique for discouraging illegal copying and distribution of copyrighted digital image information. Furthermore, it can also provide an alternative solution for image authentication. A robust watermarking and image authentication technique is proposed. The proposed scheme includes two parts. The first is a robust watermarking scheme performed in the frequency domain, which can be used to prove the ownership. The second is a standard signature process, which can be used to prove the integrity of the image. The input of the signature process is the edge properties extracted from the image. The signature can be correctly verified when the image is incidentally damaged such as lossy compression.

One function of the Police Scientific Development Branch (PSDB) is to improve the expertise of the UK Government when it purchases intelligent CCTV systems for security and policing applications. To meet this aim, PSDB evaluates and reports on the performance of such systems. To help PSDB to assess these systems rapidly, PSDB is creating a library of representative video footage to form the basis of a video test imagery library (VITAL). In the future, VITAL is used to help to establish baseline standards for performance. PSDB also intends that extracts of VITAL is published on the Internet to guide researchers on the types of footage that require automatic classification. PSDB expects VITAL footage to centre on four scenarios: parked vehicle detection; abandoned luggage detection; outdoor, sterile-zone intruder detection; and doorway surveillance. The contents of the standard video footage is taken from a larger collection set, and be weighted to contain examples of imagery that are on the boundaries of the processing capabilities of current machine-vision technology. PSDB is generating a comprehensive specification through wide consultation and plans to start collecting VITAL imagery in the autumn of 2003.

In public key cryptosystem, it is very important to protect and authenticate a user's public key. In the past, many schemes have been proposed. However, most of the schemes require one or more authorities to authenticate the public key. In the authority-based scheme, since an authority can know user's private keys or generate false certificates, we can impersonate any user at any time. Therefore, it is required such a scheme as an authority cannot know the secret information of users and a security of system does not wholly depend on an authority. In recent years, Zhan et al. proposed a new key authentication scheme, called ZLYH-scheme, which is requires no authority to authenticate a user's public key. However, it still has a weakness that can guess password. We show that ZLYH-scheme has some weakness. To overcome this disadvantage, we propose an improved key authentication scheme. In our scheme, it does not require the secret password table and an attacker cannot guess the password.

Panoramic images, especially focused images, have many applications in surveillance, robot navigation, art, etc. Described here is a CCD camera with a hyperboloidal mirror for acquiring panoramic focused images. This optical imaging system can greatly simplify the process of acquiring an omni-directional view in real time, thereby presenting panoramic still images or offering a panoramic full motion video. With this panoramic imaging system, we propose a novel approach for motion tracking of multiobjects mainly based on the idea of tracking windows. Experimental results are presented with a sequence of frames to demonstrate the superior performance of the proposed algorithm.
