| Abstract | PERG is a pattern matching engine designed for locating pre-defined byte string patterns (rules) from the ClamAV virus signature database in a data stream. This paper presents PERG-Rx, an extension of PERG that adds limited regular expression support for wildcard patterns used by rules that represent polymorphic viruses. To reduce the amount of state needed to track so many regular expressions, PERG-Rx employs a lossy scheme which increases the rate of false positives detected as the required state grows. The scalability and dynamic updatability of the PERG-Rx architecture to database updates are also evaluated. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
