Abstract

XML (eXtensible Markup Language) is fast becoming the de facto standard for information exchange over the Internet. As more and more sensitive information gets stored in the form of XML, proper access control to the XML documents becomes increasingly important. However, traditional access control methodologies that have been adapted for XML documents do not address the performance issue of access control. This paper proposes a bitmap-indexing scheme in which access control decisions can be sped up. Authorization policies of the form (subject, object, and action) are encoded as bitmaps in the same manner as XML document indexes are constructed. These two are then efficiently pipelined and manipulated for 'fast' access control and 'secure' retrieval of XML documents. Index Terms--Information security, authorization enforcement, bitmap indexing, XML access control.

4. Color image retrieval technique based on color features and image bitmap

Abstract

The field of color image retrieval has been an important research area for several decades. For the purpose of effectively retrieving more similar images from the digital image databases, this paper uses the color distributions, the mean value and the standard deviation, to represent the global characteristics of the image. Moreover, the image bitmap is used to represent the local characteristics of the image for increasing the accuracy of the retrieval system. As the experimental results indicated, the proposed technique indeed outperforms other schemes in terms of retrieval accuracy and category retrieval ability. Furthermore, the total memory space for saving the image features of the proposed method is less than Chan and Liu's method. Keywords: Image bitmap; Color distribution; Content-based image retrieval; Standard deviation

Abstract

COMPRESSION REDUCES BANDWIDTH and storage requirements by removing redundancy and irrelevancy. Redundancy occurs when data is sent when it's not needed. Irrelevancy frequently occurs in audio and video signals because [...]
