| Abstract | This paper describes a semi-automatic system to capture and label a reasonable size biometric database. In our case, the biometric to be assessed are footstep signals, but the system could be extendable to other biometrics. Extra biometric data such as the voice and video recordings of the face and the gait are used to assist the database labelling to minimise the error. Thus, audio identifier recordings are used to automatically label the database with a speaker recognition system achieving results of 0.15% of equal error rate (EER) of person verification using Gaussian mixture models (GMM). Also, a footstep detector system has been developed to reduce the presence of invalid signals from the database having a percentage of less than 1% of correct footsteps miss-classified using features from the ground reaction force (GRF) and using a support vector machine (SVM) classifier. To date, more than 20,000 footstep signals have been collected from more than 100 people, which is well beyond previously reported databases. The database is collected in different sessions which will allow us to study how different factors such as footwear, the person carrying a load or different walking speeds affect the recognition of persons using their footsteps. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
