Keyword search on encrypted data allows one to issue the search token and conduct search operations on encrypted data while still preserving keyword privacy. In the present paper, we consider the keyword search problem further and introduce a novel notion called attribute-based proxy re-encryption with keyword search (ABRKS), which introduces a promising feature: In addition to supporting keywo...

In the current information age, the dominant method for information search is by providing few keywords to a search engine. Keyword search is currently one of the most important operations in search engines and numerous other applications. In this paper we propose a new text indexing technique for improving the performance of keyword search. Our proposed technique not only speeds up searching o...

Keyword search on encrypted data enables one to search keyword ciphertexts without compromising keyword security. We further investigate this problem and propose a novel variant, dubbed certificateless keyword search on encrypted data (CLKS). CLKS not only supports keyword search on encrypted data, but also brings promising features due to the certificateless cryptography. In contrast to the ce...

Keyword search in XML Database is to provide access on XML database by overcoming keyword ambiguity. Here users are allowed to search on XML database using keyword search like Text Databases. A novel IR style approach which well captures XML’s hierarchical structure, and works well on pure keyword query independent of any schema information of XML data. A search engine prototype called XReal is...

In this paper, we explore how keyword ambiguity can affect search advertising performance. Consumers arrive at search engines with diverse interests, which are often unobserved and nontrivial to predict. The search interests of different consumers may vary even when they are searching using the same keyword. In our study, we propose an automatic way of examining keyword ambiguity based on proba...

In recent years, consumer-centric cloud computing paradigm has emerged as the development of smart electronic devices combined with the emerging cloud computing technologies. A variety of cloud services are delivered to the consumers with the premise that an effective and efficient cloud search service is achieved. For consumers, they want to find the most relevant products or data, which is hi...

Conventional search engines nd Web pages by using keyword matching. Two disadvantages for keyword matching are: (i) the order of keywords is ignored; and (ii) the approximate queries submitted by users are beyond the method of keyword matching can handle. Using keyword matching for Web page search is not satisfactory. This paper proposes a Web search system, named ApproxSeek, to facilitate Web ...
