| Abstract | In-app embedded browsers are commonly used by app developers to display web content without having to redirect the user to heavy-weight web browsers. Just like the conventional web browsers, embedded browsers can allow the execution of web code. In addition, they provide mechanisms (viz., JavaScript bridges) to give web code access to internal app code that might implement critical functionalities and expose device resources. This is intrinsically dangerous since there is currently no means for app developers to perform origin-based access control on the JavaScript bridges, and any web code running in an embedded browser is free to use all the exposed app and device resources. Previous work that addresses this problem provided access control solutions that work only for apps that are built using hybrid frameworks. Additionally, these solutions focused on protecting only the parts of JavaScript bridges that expose permissions-protected resources. In this work, our goal is to provide a generic solution that works for all apps that utilize embedded web browsers and protects all channels that give access to internal app and device resources. Towards realizing this goal, we built Draco, a uniform and fine-grained access control framework for web code running on Android embedded browsers (viz., WebView). Draco provides a declarative policy language that allows developers to define policies to specify the desired access characteristics of web origins in a fine-grained fashion, and a runtime system that dynamically enforces the policies. In contrast with previous work, we do not assume any modifications to the Android operating system, and implement Draco in the Chromium Android System WebView app to enable seamless deployment. Our evaluation of the the Draco runtime system shows that Draco incurs negligible overhead, which is in the order of microseconds. |

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.
